Description

Combination switch assembly for vehicles

technical field

The present invention relates to a combination switch assembly for a vehicle, wherein a portion for connecting wiring to a combination switch mounted on a steering column of a vehicle is improved.

Background technique

A general vehicle steering device includes: a substantially tubular steering column; a steering shaft rotatably supported in the steering column; and a steering wheel mounted on a front end portion of the steering shaft. A combination switch is installed on the steering column. The combination switch has an operating lever. The operating lever is manually operated by the driver who turns the steering wheel. The combination switch can operate a plurality of switch units by operating one operating lever up, down, left, and right.

The operating lever can be swung toward the steering wheel, that is, toward the front end side of the steering shaft. For example, by temporarily swinging the operation lever, the headlights can be blinked, or the washer fluid of the wiper device can be sprayed temporarily. Such a combination switch is known from Patent Document 1. As shown in FIG.

A combination switch known from Patent Document 1 includes a base mounted on a steering column and a plurality of lever switches mounted on the base. Each of the lever switches has an operation lever that can be swung toward the steering wheel.

A switch-side connector is formed on a surface opposite to the steering wheel on the housing of the lever switch. The switch-side connector must be located at a position separated from the steering shaft radially outward by a fixed distance or more from the steering shaft. Usually, a wiring-side connector provided on the wiring is connected to the switch-side connector by insertion. The space around the switch side connector is narrow. There may be cases where a sufficient space for connection of the wiring side connector and wiring routing cannot be secured around the switch side connector. The wiring cannot be kept with sufficient slack depending on how the wiring is drawn during wiring. In particular, since thick wiring is difficult to bend, it is difficult to maintain slack.

The dimension (depth dimension, thickness) of the combination switch in the direction of the steering axis is small. That is to say, the depth dimension of the combination switch is smaller than the dimension in the direction not along the steering axis, that is, smaller than the width. Furthermore, the case and the base of each lever switch are resin molded products. It is therefore taken into account that when the operating lever is swung towards the steering wheel, the combination switch is slightly elastically deformed along the steering axis. As a result, an external force may act on the portion connecting the wiring-side connector to the switch-side connector. Such external force is disadvantageous in improving the connectivity of the connectors with each other.

Contents of the invention

The technical subject of this invention is providing the technique which can improve the connection property of the wiring side connector with respect to the switch side connector.

According to the invention of Claim 1, there is provided a combination switch assembly for a vehicle, including: a combination switch capable of being mounted to a steering column for covering a steering shaft; and wiring for connecting to the combination switch, the combination switch It has an operation lever that can be swung toward the steering wheel mounted on the steering shaft, and the wiring-side connector provided on the above-mentioned wiring can be connected to the switch-side connector provided on the above-mentioned combination switch. The switch assembly is characterized in that a wire holding member independent from the wire side connector and located near the wire side connector is installed on the wire, and a wire holding member for hooking the wire is installed on the combination switch. The hooking portion of the holding member is arranged at a position where the wire holding member can be hooked in a state where the wire side connector is connected to the switch side connector.

As described in item 2, it is preferable that the above-mentioned wiring holding member is constituted by: a band that is directly attached to an electric wire group composed of a plurality of covered electric wires in the above-mentioned wiring; The belt is integrally formed and hooked on the above-mentioned hooking portion.

As described in solution 3, it is more preferable that the above-mentioned clip is formed as a branch shape with two legs for clamping the above-mentioned hook part in an elastic manner, and the front ends of the two legs are provided with The two locking protrusions facing each other are used to be hooked on the hooking portion when the hooking portion is sandwiched by the two legs.

As described in claim 4, it is more preferable that the engaging portion is located radially outward of the steering shaft relative to the steering shaft relative to a position of the switch-side connector.

Invention effect

In the invention of Claim 1, the wire holding member independent from the wire-side connector and positioned near the wire-side connector is attached to the wire. On the other hand, in addition to the switch-side connector, a hook portion is provided on the combination switch. Therefore, the connection state of the wire-side connector to the switch-side connector can be maintained by hooking the wire holding member to the hook portion. That is, an external force in a direction to cause the wiring-side connector to fall does not act on the portion where the wiring-side connector is connected to the switch-side connector. Therefore, the connectivity of the wiring-side connector to the switch-side connector can be improved. For example, even when the casing of the combination switch is a resin molded product and the depth dimension of the combination switch is smaller than other dimensions, the connection between the connectors can be maintained satisfactorily.

In the invention of claim 2, the band of the wiring holding member is directly attached to the group of electric wires composed of a plurality of covered electric wires in the wiring. Therefore, it is possible to more reliably restrict the external force acting on the wiring-side connector from the wiring. As a result, the connectivity between the connectors can be maintained even more favorably. For example, compared with the case where the wire holding member is attached to the corrugated tube covering the wire, the external force acting on the wire-side connector from the wire can be sufficiently restricted. In addition, since the clip of the wire holding member can be hooked to the hooking portion, the hooking operation of the wire holding member to the hooking portion is facilitated.

In the invention of Claim 3, the two legs of the branched clip have two locking protrusions. When the hooking portion is clamped by the two legs, the two locking protrusions are hooked on the hooking portion. Therefore, in the process of connecting the wiring-side connector to the switch-side connector, it is possible to perform the work of inserting and hooking the clip into the hooking portion. That is, since a series of operations including the connector connection operation and the clip engagement operation can be performed simply and easily, it is possible to suppress as much as possible an increase in the number of assembly man-hours for wiring to the combination switch. Therefore, the productivity of the vehicle can be maintained.

In the invention of claim 4, the hook portion is located on the radially outer side of the steering shaft than the position of the switch-side connector with respect to the steering shaft. Here, it is assumed that the combination switch undergoes a slight elastic deformation along the steering axis, for example when the operating lever is swiveled towards the steering wheel. In this case, the external force due to the elastic deformation can be received by the hooking portion and the hooking portion of the wire holding member. Therefore, the hook portion can sufficiently suppress the external force acting on the portion connecting the wiring-side connector to the switch-side connector.

The wiper switch includes a wiper switch unit and a washer switch unit.

When the first operation lever 32 at the neutral position is swung vertically, the wiper switch unit is switched. According to the switching operation of the wiper switch unit, a wiper motor (not shown) drives a wiper blade (not shown).

Further, the first operating lever 32 can be pivotally operated toward the steering wheel 13 attached to the steering shaft 12 (in the direction of the arrow R2). By repeatedly swinging the first operating lever 32 located at the neutral position toward the steering wheel 13, the washer switch unit is turned on and off. According to this on-off operation, a washer pump (not shown) operates to spray washer fluid onto the windshield.

The second switch unit 40 is used as, for example, a turn signal switch unit. The second switch unit 40 (turn signal switch unit 40 ) is composed of a case 41 , a lamp switch (not shown) built in the case 41 , and a second operating lever 42 for operating the lamp switch. The second control lever 42 is mounted on the left side in the vehicle width direction of the housing 41 in a swingable manner, and can be moved in the vertical direction (arrow R3 direction) in the state assembled to the steering column 11 . swing operation. The lamp switch includes a right-turn lighting switch unit, a left-turn lighting switch unit and a passing switch unit.

When the second operation lever 42 located in the neutral position is swung in the lifting direction, the right turn lighting switch is turned on. According to the turning-on operation of the right turn lighting switch unit, the right indicator light (not shown) blinks. When the second operation lever 42 is swung in the downward direction, the left turn lighting switch is turned on. According to the turning-on operation of the left-turn lighting switch unit, the left indicator light (not shown) blinks.

Further, the second operating lever 42 can be pivotally operated toward the steering wheel 13 attached to the steering shaft 12 (in the direction of the arrow R4). By repeatedly swinging the second control lever 42 at the neutral position toward the steering wheel 13 , the on-off operation of the passing switch unit is performed. According to this switching operation, the left and right headlights (not shown) blink.

As described above, the combination switch 21 has two operating levers 32 and 42 that can be swung toward the steering wheel 13 attached to the steering shaft 12 . The two operating levers 32 , 42 are located on both sides in the vehicle width direction with respect to the steering shaft 12 , and extend outward from the two housings 31 , 41 in the vehicle width direction. In addition, although the relationship between each control lever 32, 42 and a load was demonstrated as an example, it can set arbitrarily.

The common base 22 and the left and right casings 31 and 41 are resin molded products. As shown in FIG. 2 , the combination switch 21 has a small dimension Th in the direction along the steering shaft 12 (direction along the center line CL of the steering shaft 12 ), that is, a depth dimension Th (thickness Th). That is to say, the depth dimension Th of the combination switch 21 is smaller than the dimensions Hi and Wi in the direction not along the steering shaft 12 , that is, smaller than the height Hi and the width Wi.

As shown in FIG. 2, on the back surfaces 31a, 41a of the housings 31, 41 of the first and second switch units 30, 40, that is, on the surfaces 31a, 41a opposite to the steering wheel 13 (refer to FIG. 1 ). , the switch-side connectors 33, 43 are integrally formed, respectively.

The first switch-side connector 33 provided on the first switch unit 30 can be connected to the first wiring by inserting the first wiring-side connector 53 from the back surface 31a side of the casing 31 of the first switch unit 30 . The side connector 53 is connected. The first wiring side connector 53 is provided at one end of the first wiring 50 .

The second switch side connector 43 provided on the second switch unit 40 can be connected to the second wiring side connector 63 by inserting the second wiring side connector 63 from the back surface 41a side of the casing 41 of the second switch unit 40 . The side connector 63 is connected. The second wiring side connector 63 is provided at one end of the second wiring 60 .

Each of the switch side connectors 33 and 43 is located at a position separated from the steering shaft 12 (with respect to the center line CL of the steering shaft 12 ) by a fixed distance L1 and L2 radially outward of the shaft 12 .

The first wiring 50 includes an electric wire group 52 composed of a plurality of covered electric wires 51 . The second wiring 60 includes an electric wire group 62 composed of a plurality of covered electric wires 61 . The plurality of covered electric wires 51 and 61 are electric wires each having an electrically insulating coating layer applied to the surface of each conducting wire. The conductor consists of, for example, a wire or a stranded wire. The number of the plurality of covered electric wires 51 , 61 is determined according to the number of terminals of the respective switch side connectors 33 , 43 . The electric wire groups 52, 62 are aggregates of a plurality of covered electric wires 51, 61, respectively. In this manner, the wiring-side connectors 53 , 63 provided on the wiring lines 50 , 60 can be connected to the switch-side connectors 33 , 43 provided on the combination switch 21 .

And the respective wirings 50, 60 are covered by protective tubes 54, 64, respectively, thereby protecting them from external damage. The protective tubes 54 and 64 are formed of, for example, corrugated tubes. However, regarding the parts 55, 65 near the ends connected to the wiring side connectors 53, 63 among the wirings 50, 60, that is, the non-covered parts 55, 65, the plurality of covered electric wires 51, 61 are not covered. The protective tubes 54 and 64 are covered and directly exposed to the outside.

A "combination switch assembly 20 for a vehicle" is constituted by a combination switch 21 and two wires 50 and 60 for connecting to the combination switch 21 .

Each switch built in the combination switch 21, that is, the first and second switch units 30, 40 directly turns on and off a load with a large capacity (lamp and motor), and flows a large current. Such a switch is usually called a direct control switch. Since the wirings 50 and 60 are connected to the combination switch 21 through which a large current flows, relatively thick wires are used. Since the thick wiring 50, 60 is difficult to bend, it is difficult to maintain slack.

On the first and second wiring 50, 60, the first and second wiring retainers located near the first and second wiring side connectors 53, 63, that is, on the non-covered parts 55, 65 are installed respectively. Parts 56, 66. The first and second wiring holding members 56 and 66 are separate members from the first and second wiring side connectors 53 and 63 .

On the other hand, the combination switch 21 is provided with first and second hooking portions 34 , 44 for hooking the first and second wiring holding members 56 , 66 . The first and second hooking parts 34, 44 are arranged at positions where the first and second wiring side connectors 53, 63 are connected to the first and second switch side connectors 33, 43. In the state, the positions of the first and second wire holding members 56 and 66 can be hooked.

In detail, the first hooking portion 34 is a member for hooking the first wiring holding member 56 attached to the first wiring side connector 53 , and is located near the first switch side connector 33 . The first hook portion 34 is located on the “outer side” of the steering shaft 12 in the radial direction than the position of the first switch-side connector 33 with respect to the steering shaft 12 .

The second hooking portion 44 is a member to be hooked by the second wiring holding member 66 attached to the second wiring side connector 63 , and is located near the second switch side connector 43 . The second hook portion 44 is located “inward” in the radial direction of the steering shaft 12 relative to the steering shaft 12 from the position of the second switch-side connector 43 . In addition, this 2nd hook part 44 can be located in "outer side" similarly to the 1st hook part 34. As shown in FIG.

Hereinafter, the first hooking portion 34 and the first wire holding member 56 will be described in detail based on FIGS. 3 to 6 . In addition, since the 2nd hook part 44 has the same structure as the 1st hook part 34, the same code|symbol is attached|subjected, and description is abbreviate|omitted. Since the second wiring holding member 66 has the same structure as the first wiring holding member 56 , the same reference numerals are used and description thereof will be omitted.

As shown in FIGS. 3 and 4 , the first wiring holding member 56 is a resin integrally molded product, and is composed of the following parts: a band 71 , which is directly attached to the non-covered portion 55 of the first wiring 50 by On an electric wire group 52 constituted by a plurality of covered electric wires 51 ; and a clip 75 integrally formed with this band 71 .

The belt 71 is composed of a flexible belt-shaped belt main body 72 and a buckle 73 integrally provided at the proximal end of the belt main body 72 . The length of the belt main body 72 can be adjusted and locked by inserting the front end portion of the belt main body 72 into the buckle portion 73 .

The procedure for attaching the first wiring holding member 56 to the first wiring 50 is as follows. First, the band main body 72 is directly wound around the electric wire group 52 in the non-covering portion 55 of the first wiring 50 . Next, the front end portion of the belt main body 72 after being wound is inserted into the buckle portion 73 and fastened. Thereby, the installation operation|work of the 1st wire holding member 56 with respect to the 1st wire 50 is completed.

The clip 75 is a member that is clipped and clipped to the first clip 34 . In detail, as shown in FIGS. 4 and 5 , the clip 75 is formed in a branched shape having two legs 76 , 76 . Taking the bent molded product as an example, the clip 75 is formed in a substantially U-shaped shape by bending a strip plate having a width Hc in the plate thickness direction. In this clip 75 , a portion 77 corresponding to a bent portion is a closed end 77 (base ends 77 of the two leg portions 76 , 76 ). In this clip 75 , a portion 78 opposite to the closed end 77 is an open end 78 .

The two leg parts 76 and 76 can be elastically deformed in the directions of approaching and separating from each other with the base end 77 as a reference, that is, they have elasticity. Two guiding protrusions 79 , 79 facing each other are formed on front end portions 76 a , 76 a of the two leg portions 76 , 76 . The two guide protrusions 79 , 79 protrude from the respective leg portions 76 , 76 in directions facing each other, and are formed over the entire width Hc of the respective leg portions 76 , 76 . These two guiding protrusions 79 , 79 are formed in an inclined shape in a direction narrowing from the open end 78 side of the clip 75 toward the closed end 77 side.

On the inner surface of the substantially U-shaped clip 75, a hook auxiliary member 81 formed along the inner surface is provided. The elastic deformation of the respective leg portions 76 , 76 of the clip 75 in the direction of mutual approach and distance is assisted by the hook assist member 81 .

The hooking auxiliary part 81 is made of an elastic plate, such as a "spring steel plate", and is integrated with the clip 75 by insert molding on the clip 75, for example. In more detail, the hook auxiliary member 81 is formed by bending a strip plate having the same width Hc as the clip 75 in a substantially U-shape in the thickness direction, that is, it is formed to have two elastic legs 82 , 82 . branched.

The two elastic legs 82 and 82 can be elastically deformed in the directions of approaching and moving away from each other based on the base end 83 (closed end 83 of the hooking auxiliary part 81 ), that is, elastic. On the front end portions 82a, 82a of the two elastic leg portions 82, 82, two locking convex portions 84, 84 facing each other are formed. The two locking protrusions 84 , 84 are folded back from the front ends 82 a , 82 a of the elastic legs 82 , 82 in directions facing each other, and are formed over the entire width Hc of the elastic legs 82 , 82 .

Furthermore, the two locking protrusions 84, 84 are structured as hooking claws, and the locking claws are formed so as to be spaced apart from each other in a direction narrowing from the open end 85 side toward the closed end 83 side of the hooking auxiliary member 81. inclined shape. Therefore, the two locking protrusions 84 , 84 can hold the first locking portion 34 elastically. Furthermore, the two locking protrusions 84 , 84 are supported by the back surfaces of the guiding protrusions 79 , 79 of the two leg portions 76 , 76 .

In this way, on the front end portions 76a, 76a of the two leg portions 76, 76, two locking protrusions 84, 84 facing each other are provided for clamping by the two leg portions 76, 76. In the case of the hooking portion 34 , it is hooked on the hooking portion 34 .

The first hook portion 34 is an elongated bar linearly extending rearward from the rear surface 31a of the case 31 of the first switch unit 30 , that is, to the opposite side with respect to the steering wheel 13 (see FIG. 1 ). , and parallel to the first switch-side connector 33 . Therefore, with respect to the direction in which the first wiring side connector 53 is connected to the first switch side connector 33 (arrow A1 direction in FIG. The direction of the arrow A2) is the same.

Furthermore, the first engaging portion 34 is formed in an I-shaped cross-section, and consists of a vertical plate-shaped core material 91 and two horizontal plate-shaped flanges 92, 92 integrally formed on the upper end and lower end of the core material 91. constitute. That is, the two flanges 92 , 92 are at positions perpendicular to the core material 91 . Since the first hook portion 34 has an I-shaped cross section, it has high bending rigidity and torsional rigidity. Therefore, it is possible to sufficiently withstand the external force transmitted from the first wiring 50 via the clip 75 .

Furthermore, the interval Hf between the flanges 92 and 92 is set slightly larger than the width Hc of the clip 75 . Therefore, insertion of the clip 75 into the first hook portion 34 is facilitated. In addition, the clip 75 held by the first hook portion 34 is restricted from tilting by the flanges 92 , 92 . Therefore, the clamping state of the clip 75 with respect to the 1st hook part 34 becomes stable.

As shown in FIG. 5 , the thickness t1 of the core material 91 is slightly larger than the gap S1 between the guiding convex parts 79 and 79 of the two leg parts 76 and 76 . The gap S1 between the guiding convex parts 79 and 79 of the two leg parts 76 and 76 is larger than the gap S2 between the front ends 84a and 84a of the two locking convex parts 84 and 84 (t1>S1>S2) .

The procedure for hooking the clip 75 to the first hooking portion 34 is as follows. First, as shown in FIG. 5 , the clip 75 is inserted into the front end of the first hook portion 34 from the side of the open end 78 , that is, from the direction of the arrow A2 . Then, the two guiding protrusions 79 , 79 are expanded by the core material 91 .

The clip 75 is further inserted into the core material 91 . Then, the two locking protrusions 84 , 84 are expanded by the core material 91 . At this time, the front ends 84a, 84a of the two locking convex parts 84, 84 advance while biting into the plate surface of the core material 91 .

Then, as shown in FIG. 6 , the clip 75 is inserted to a predetermined position with respect to the first hook portion 34 , for example, to the closed end 83 of the hook auxiliary member 81 . In this state, the front ends 84a, 84a of the two locking protrusions 84, 84 are bitten into and hooked by the biasing force of the legs 76, 76 of the clip 75 and the biasing force of the hooking auxiliary member 81. The board face of the core material 91 . Thus, the hooking operation of the clip 75 with respect to the first hooking portion 34 is completed.

Although the situation is as described above, as shown in FIG. Same as it. For this reason, the direction of the U-shaped cross section of the clip 75 is set to a direction perpendicular to the belt surface of the belt-shaped belt main body 72 , that is, the belt width direction.

Next, an example of the connection procedure of the combination switch 21 in a state where the first wiring 50 is attached to the steering column 11 (see FIG. 1 ) will be described based on FIGS. 3 and 4 . First, the first wiring 50 to which the first wiring holding member 56 is mounted is prepared. Next, the first wiring side connector 53 is connected to the first switch side connector 33 . Next, the clip 75 is inserted into the first hook portion 34 to complete the connection work.

As a result, the wire holding member 56 can be hooked to the hook portion 34 in a state where the wire side connector 53 is connected to the switch side connector 33 . That is, the two leg portions 76 , 76 elastically sandwich both surfaces of the core material 91 of the first hooking portion 34 via the hooking auxiliary member 81 . And as shown in FIG. 6, the front-end|tip 84a, 84a of the two locking convex parts 84, 84 bites into and engages with the both surfaces of the core material 91. As shown in FIG.

Therefore, it is possible to sufficiently restrict the clip 75 from coming off in the detachment direction (direction of arrow A3 in FIG. 6 ) with respect to the first hooking portion 34 . Therefore, the hooked state of the wiring side connector 53 with respect to the 1st hooking part 34 is extremely firm. No external force in the detachment direction acts on the portion where the first wiring side connector 53 is connected to the first switch side connector 33 .

The description of Example 1 is summarized as follows. As shown in FIG. 2, on the first and second wiring 50, 60, a connector 53 that is independent from the first and second wiring side connectors 53, 63 and located on the first and second wiring side is installed. , 63 near the first and second wiring holding members 56,66. On the other hand, in addition to the first and second switch-side connectors 33 and 43 , the combination switch 21 is provided with first and second hook portions 34 and 44 . Therefore, by hooking the first and second wiring holding members 56, 66 to the first and second hooking portions 34, 44, the first and second wiring-side connectors 53, 63 can be maintained relative to each other. The connection state of the first and second switch-side connectors 33 and 43 .

That is to say, the first and second wiring side connectors 53, 63 are connected to the first and second switch side connectors 33, 43, and the first and second wiring side connectors are not affected. External force in the direction in which the side connectors 53 and 63 fall off. Therefore, the connectivity of the first and second wiring-side connectors 53 and 63 to the first and second switch-side connectors 33 and 43 can be improved.

For example, even when the housings 31, 41 of the combination switch 21 are resin molded products and the depth dimension Th of the combination switch 21 is smaller than other dimensions Wi, Hi, the relationship between the connectors 33, 53 can be maintained well. Between and the connectivity between the connectors 43, 63.

Moreover, as shown in FIGS. 2 to 4, the bands 71, 71 of the first and second wire holding members 56, 66 are directly mounted on the first and second wires 50, 60, which are made of a plurality of covered wires. On the wire group 52,62 that 51,61 constitutes. Therefore, the external force acting on the first and second wiring side connectors 53 , 63 from the first and second wiring 50 , 60 can be more reliably restricted. Therefore, the connectivity between the connectors 33 and 53 and between the connectors 43 and 63 can be maintained further favorably.

For example, compared with the case where the first and second wire holding members 56, 66 are attached to the protective tubes 54, 64 covering the first and second wires 50, 60, The external force acting on the first and second wiring side connectors 53 , 63 by the first and second wiring 50 , 60 . In addition, since the clips 75, 75 of the first and second wiring holding members 56, 66 can be clipped and clipped on the first and second clips 34, 44, the first and second clips are easily performed. And the hooking operation of the second wiring holding members 56 and 66 with respect to the first and second hooking parts 34 and 44 .

Furthermore, as shown in FIGS. 5 and 6 , the two leg portions 76 , 76 of the branched clip 75 of the first wiring holding member 56 have two locking protrusions 84 , 84 . When the first hooking portion 34 is sandwiched by the two leg portions 76 , 76 , the two locking protrusions 84 , 84 are hooked to the first hooking portion 34 .

Therefore, in the step of connecting the first wiring-side connector 53 to the first switch-side connector 33 , it is possible to insert and hook the clip 75 into the first hooking portion 34 . That is, since the series of operations of connecting the first connectors 33, 53 and the clipping operation can be performed simply and easily, the first wiring 50 can be suppressed as much as possible relative to the combination switch 21. An increase in assembly man-hours. Therefore, the productivity of the vehicle can be maintained. The effect is the same with respect to the relationship between the second hook portion 44 and the second wire holding member 66 shown in FIG. 2 , and description thereof will be omitted.

Furthermore, as shown in FIG. 2 , the first hook portion 34 is located on the radially outer side of the steering shaft 12 relative to the position of the first switch-side connector 33 with respect to the steering shaft 12 . Here, it is assumed that, for example, when the first operating lever 32 is swung toward the steering wheel 13 , the combination switch 21 is slightly elastically deformed along the steering shaft 12 (see FIG. 1 ). In this case, the external force due to the elastic deformation can be received by the engaging portion between the first engaging portion 34 and the first wiring holding member 56 . Therefore, the external force acting on the portion connecting the first wiring-side connector 53 to the first switch-side connector 33 can be sufficiently suppressed by the first hooking portion 34 .

Example 2

A combination switch assembly for a vehicle according to Embodiment 2 will be described based on FIGS. 7 to 9 . FIG. 7 is shown correspondingly to FIG. 3 described above. FIG. 8 is shown correspondingly to FIG. 4 described above. The vehicle combined switch assembly 120 of the second embodiment is characterized in that the clips 75, 75 of the first embodiment shown in FIGS. 2 to 6 are changed to the clips 175 shown in FIGS. The other structures are the same as those of Embodiment 1 shown in FIGS. 1 to 6 above, so descriptions thereof are omitted.

More specifically, as shown in FIGS. 7 and 8 , the clip 175 is a member that is clipped and clipped to the first clip 34 , and is integrally formed with the above-mentioned belt 71 . The clip 175 is formed in a branched shape having two legs 176 , 176 . Taking the bent molded product as an example, the clip 175 is formed in a substantially U-shaped shape by bending a strip plate having a width Hc in the plate thickness direction. In this clip 175, a portion 177 corresponding to a bent portion is a closed end 177 (base ends 177 of the two leg portions 176, 176). In this clip 175 , a portion 178 opposite to the closed end 177 is an open end 178 . The direction of the U-shaped cross section of the clip 175 is set to be a direction perpendicular to the belt surface of the belt-shaped belt main body 72 , that is, the belt width direction.

The two leg parts 176 and 176 can be elastically deformed in directions of approaching and separating from each other with the base end 177 as a reference, that is, they have elasticity. Therefore, the two leg portions 176 , 176 can hold the first hook portion 34 elastically. Two locking protrusions 179 , 179 facing each other are formed on front end portions 176 a , 176 a of the two leg portions 176 , 176 . The two locking protrusions 179 , 179 protrude from the respective leg portions 176 , 176 in directions facing each other, and are formed over the entire width Hc of the respective leg portions 176 , 176 .

The two locking protrusions 179 , 179 are formed in an inclined shape in a direction narrowing from the open end 178 side of the clip 175 toward the closed end 177 side, that is, with respect to the inner surfaces of the leg portions 176 , 176 . Formed into a substantially right triangle shape. Therefore, the end surfaces 179a, 179a of the two locking protrusions 179, 179 near the closed end 177 are formed in a hook shape at right angles to the inner surfaces of the leg portions 176, 176 .

As shown in FIG. 9 , the thickness t1 of the core material 91 is set to be substantially the same as the interval t2 between the two leg portions 176 , 176 . The first hooking portion 34 has two locking recesses 93 , 93 to which the two locking protrusions 179 , 179 are caught when sandwiched between the two leg portions 176 , 176 . That is, locking recesses 93 , 93 are respectively formed on both surfaces of the vertical plate-shaped core material 81 . As shown in FIGS. 8 and 9 , the two locking recesses 93 , 93 are formed over the entire interval Hf between the flanges 92 , 92 . The two locking recesses 93 , 93 are formed in a substantially right-angled triangle shape substantially matching the shape and size of the two locking protrusions 179 , 179 . Therefore, the end surfaces 93 a , 93 a of the two locking recesses 93 , 93 near the front end of the core material 91 are formed in a hook shape at right angles to the plate surface of the core material 91 .

Next, an example of the connection sequence of the first wiring 50 to the combination switch 21 in the state attached to the steering column 11 (see FIG. 1 ) will be described based on FIGS. 7 and 8 . First, the first wiring 50 to which the first wiring holding member 56 is mounted is prepared. Next, the first wiring side connector 53 is connected to the first switch side connector 33 . Next, the clip 175 is inserted into the first hooking portion 34 to complete the connection work.

As a result, the wire holding member 56 can be hooked to the hook portion 34 in a state where the wire side connector 53 is connected to the switch side connector 33 . That is, the two leg portions 176 , 176 elastically sandwich both surfaces of the core material 91 of the first hook portion 34 . At the same time, the two locking protrusions 179 , 179 are engaged with the two locking recesses 93 , 93 . 9, end surfaces 179a, 179a of hook-shaped locking protrusions 179, 179 are hooked on end surfaces 93a, 93a of hook-shaped locking recesses 93, 93.

Therefore, it is possible to sufficiently restrict the clip 175 from coming off in the detachment direction (arrow A3 direction in FIG. 9 ) with respect to the first hook portion 34 . Therefore, the hooked state of the wiring side connector 53 with respect to the 1st hooking part 34 is extremely firm. No external force in the detachment direction acts on the portion connecting the first wiring side connector 53 to the first switch side connector 33 .

According to the second embodiment, the same functions and effects as those of the first embodiment described above are exhibited.

In the present invention, the combined switch 21 may be a so-called integrated switch in which the components of the first and second switch units 30 and 40 are incorporated into one housing.
