JP-A-2005-19188

  In the above structure, the connector housing fitted in the shield shell is likely to be displaced to the open side of the shield shell, and may be detached from the shield shell. Therefore, in order to prevent the displacement of the connector housing, it is conceivable to attach a plate member so as to close the open side of the shield shell, and hook the connector housing on the plate member to support it. However, such a method is not preferable from the viewpoint of increasing the number of parts by the number of plate members, and additionally requiring a new work of attaching the plate members, which complicates parts management and increases manufacturing costs.

  The present invention has been completed based on the above circumstances, and is a shielded connector that can prevent the connector housing from being displaced toward the open side of the shield shell while avoiding an increase in the number of parts and work processes. For the purpose of provision.

As means for achieving the above object, the invention of claim 1 is directed to a connector housing fitted into a device-side housing housed in a shield case, an electric wire led out from the rear surface of the connector housing, A shield shell which accommodates the connector housing and is attached to the shield case so as to be conductive, and an opening for fitting the connector housing opens in the shield shell in a direction substantially perpendicular to the lead-out direction of the electric wire. The shield shell is a shield connector attached to the shield case with the surface on the side where the opening is provided facing the shield case, and the front end of the connector housing is attached to the front end of the shield shell. Front restricting portion for restricting the displacement of the portion in the opening direction of the opening Provided, the front restricting portion is concave or convex, in the connector housing and the mating regulating portion is provided to be fitted to the front restricting portion, the rear end portion of the shield shell A rear restricting portion that restricts the electric wire from being displaced in the opening direction of the opening is provided, and the shield shell includes a holding portion that holds the restricting state of the front restricting portion in the shield shell. The connector housing is provided so as to protrude toward the housing space side, and the connector housing is provided with a locking holding portion that is locked from the front with respect to the holding portion, and the holding portion and the locking holding portion At least one of them is characterized in that it can be elastically bent in the crossing direction with respect to the fitting direction of the front restricting portion and the fitting restricting portion .

The invention of claim 2 is the one described in claim 1, when the connector Howe sequencing is assembled to the shield shell along the fitting direction of the fitting regulating portion and the front restricting portion, the holding portion And at least any one of the surfaces facing each other in the latch holding portion is characterized in that a guide surface that is inclined with respect to the fitting direction is provided.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the front restricting portion is a concave shape, and the fitting restricting portion is a protrusion that is fitted into the front restricting portion. The front portion restricting portion is a hole portion that is formed through the front wall portion of the shield shell to communicate the accommodating space with the external space.

The invention of claim 4 is characterized in that, in the invention described in claim 3 , the projecting end of the protruding portion reaches an outer position from the outer peripheral surface of the shield shell.

<Invention of Claim 1>
The front end portion of the shield shell is provided with a front portion restricting portion that restricts displacement of the front end portion of the connector housing in the opening direction of the opening portion, and the shield shell holds the restricted state of the front portion restricting portion. A holding part is provided. In addition, a rear portion restricting portion that restricts the electric wire from being displaced in the opening direction of the opening portion is provided at the rear end portion of the shield shell. As a result, the connector housing is restricted from displacement in the opening direction of the opening portion of the shield shell at both front and rear end portions.
Thus, according to the configuration of the present invention, the connector housing is displaced in the opening direction of the opening only by assembling the connector housing to the shield shell without taking measures such as directing the plate member to the opening. As a result, it can be prevented from coming off the shield shell.

In addition, since at least one of the holding portion and the locking holding portion can be elastically bent in the crossing direction with respect to the fitting direction of the front restricting portion and the fitting restricting portion, the connector housing is fitted with this fitting. Even when the holding portion and the locking holding portion come into contact with each other when assembled to the shield shell along the direction, at least one of them bends and retracts in the crossing direction with respect to the fitting direction. When the connector housing reaches the normal position, the retracted holding portion or the locking holding portion is elastically restored and locked to each other. As a result, when the connector housing is assembled to the shield shell, even if the holding portion and the locking holding portion come into contact with each other, it will not interfere with the assembly work, so avoid contact between the front restriction portion and the fitting restriction portion. Thus, the connector housing may not be inserted obliquely with respect to the fitting direction. Therefore, the connector housing can be assembled smoothly.

<Invention of Claim 2 >
When the connector housing is assembled to the shield shell, since at least one of the surfaces facing each other in the holding portion and the locking holding portion is provided with a guide surface, when these surfaces come into contact with each other, As compared with the case where the guide surface is not provided, it becomes difficult to be caught and the assembling work can be performed more smoothly.

<Invention of Claim 3 >
Since the front restricting portion is formed through the front wall portion of the shield shell and communicates with the housing space of the connector housing in the shield case and the external space, the protrusion of the connector housing is inserted into the front restricting portion. You can see what is being done from the outside. Thereby, regulation by a front part regulation part is made reliably.

<Invention of Claim 4 >
Since the protruding end of the protrusion reaches an outer position from the outer peripheral surface of the shield shell, this protrusion is less likely to come off from the front restricting portion than when it does not penetrate the wall of the shield shell, and the connector housing is more reliable. Can be prevented from being displaced in the opening direction of the opening.

(See also 9). As shown in FIG. 3, the locking pieces 25 are provided at two locations, one at each terminal accommodating portion 21 </ b> A, and are extended in a cantilevered manner from the rear surface of the fitting portion 22 toward the rear. ing. The locking piece 25 is provided at a position spaced downward from the upper end of the fitting portion 22, and the upper and lower sides of the locking piece 25 are open, so that the vertical direction (the fitting of the protruding portion 24 and the restriction window 36 is fitted). It is possible to bend elastically in the direction intersecting the alignment direction. The locking piece 25 is formed at a position that fits in the accommodation space S of the shield shell 30.

  At a position near the rear end on the upper surface of the locking piece 25, a locking projection 26 protruding upward from the upper surface is provided. The rear side surface 26A of the locking projection 26 is substantially perpendicular to the upper surface of the locking piece 25, while the front side surface is a housing side guide surface 26B that is inclined forward.

  The connector housing 20 and the front end portion of the electric wire 10 led out from the connector housing 20 are covered with a shield shell 30 from above. 6, 7, and 8 are a plan view, a front view, and a rear view of the shield shell 30.

  The shield shell 30 is made of aluminum die cast, and includes a housing portion 31 that houses the connector housing 20 and the ends of the electric wires 10, and an attachment portion 32 that is attached to the shield case.

  The accommodating portion 31 includes a plate-like lid plate portion 33 that covers the upper surface side of the connector housing 20 and the lead-out portion of the electric wire 10, and a side wall portion 34 that hangs downward along the periphery of the lid plate portion 33. As a whole, it is formed in a shallow dish shape that opens downward (substantially perpendicular to the direction in which the electric wire 10 is led out). The side wall 34 is suspended until the lower end reaches the lower surface position of the housing main body 21. And the internal space of the accommodating part 31 becomes the accommodating space S where the lower surface was open | released largely, and the connector housing 20 is engage | inserted from the opening part 35 of a lower surface. A substantially front half portion of the accommodating portion 31 is a housing-corresponding portion 31A having substantially the same shape as the connector housing 20, and a substantially latter half portion has a width capable of accommodating the lead-out portions of the three electric wires 10 arranged in the width direction. Moreover, it is set as the electric wire corresponding | compatible part 31B which makes the inclination which goes up toward back a little. When the connector housing 20 is housed in the regular position in the housing space S, the upper surface, the side surface, and the front surface of the connector housing 20 abut against the inner circumferential surface of the shield shell 30, and the connector housing 20 contacts the shield shell 30. On the other hand, it does not move upward, laterally, and forward.

  The attachment portion 32 is formed in a portion corresponding to the fitting portion 22 of the connector housing 20 on the lower surface of the shield shell 30, specifically, a portion extending from the front side edge on the periphery of the opening 35 to the substantially front half portion on the side edge. . The attachment portion 32 has a plate shape protruding outward from the peripheral edge of the opening 35, and a portion along the front side edge protrudes by a certain width, and a portion along the side edge gradually protrudes rearward. The width is increased. Bolt holes 32 </ b> A penetrating in the vertical direction are formed at two places in total in the width direction both ends of the attachment portion 32, one place at a time. The shield shell 30 is attached to the shield case with the opening 35 facing the upper surface of the shield case, is bolted at the bolt hole 32A position, and is connected to the shield case so as to be conductive.

  A restriction window 36 (corresponding to the front restriction part of the present invention) is formed in the front side wall part 34F along the front edge of the cover plate part 33 in the side wall part 34 of the shield shell 30. 9 is a side sectional view showing a state in which the protrusion 24 is fitted to the restriction window 36 and the locking piece 25 is locked to the holding protrusion 38, and FIG. The side sectional view showing the state which separated connector housing 20 and shield shell 30 was shown.

  The restricting windows 36 are provided at two positions in the front side wall portion 34F near the both ends in the width direction, in other words, at positions corresponding to the protruding portions 24 of the connector housing 20. Each restricting window 36 passes through the front side wall portion 34F in the front-rear direction (the protruding direction of the protruding portion 24), and communicates the housing space S of the shield shell 30 with the external space. Each restricting window 36 opens from a position corresponding to the upper surface of the mounting portion 32 to the front end portion of the lid plate portion 33, has a rectangular shape slightly longer in the width direction when viewed from the front, and has a cross section of the protruding portion 24. The shape is almost the same as the shape. The projecting portions 24 are fitted into the restricting windows 36 from the rear (inside the shield shell 30), respectively, and the projecting end of the projecting portion 24 is positioned forward of the front side wall portion 34 </ b> F of the shield shell 30 in a properly fitted state. It has come to. In addition, the lower side surface of the peripheral surface forming the restriction window 36 and the upper surface of the mounting portion 32 connected to the lower side surface constitute a restriction surface 36A that can contact the lower surface 24A of the protruding portion 24 from the lower side. The regulation surface 36A extends over the entire lower surface 24A of the protrusion 24.

  Further, in the rear side wall portion 34R along the rear edge of the cover plate portion 33 in the side wall portion 34 of the shield shell 30, a lead-out port 37 (corresponding to the rear portion regulation portion of the present invention) through which the electric wire 10 is led is formed. ing. The outlet 37 penetrates the rear side wall portion 34R in the front-rear direction (wall thickness direction), and the electric wire 10 connected to the connector housing 20 can be led out rearward. The lead-out port 37 has a wide cross-sectional shape through which the three electric wires 10 arranged in parallel in the width direction can be collectively inserted, and both end portions in the width direction have a semicircular arc shape recessed on both sides. In addition, the part derived | led-out from the shield shell 30 in the electric wire 10 is surrounded by the shield member (not shown) which comprises the flat cylinder shape which consists of a braided wire, and is collectively shielded.

  A holding projection 38 (corresponding to the holding portion of the present invention) is provided at a substantially central portion in the front-rear direction on the lower surface of the cover plate portion 33 of the shield shell 30, in other words, at the rear end portion of the housing corresponding portion 31A in the cover plate portion 33. Is provided. The holding protrusions 38 are arranged at two positions, one at a position corresponding to the locking piece 25 of the connector housing 20. Each holding projection 38 projects downward from the lower surface of the lid plate portion 33 (on the housing space S side in the connector housing 20), and its projecting end is a position slightly below the center in the height direction in the housing space S, in other words. As a result, the position of the upper surface of the locking piece 25 is almost the same. The front side surface 38A of the holding projection 38 is substantially perpendicular to the lower surface of the lid plate portion 33. When the connector housing 20 is fitted in the accommodation space S of the shield shell 30 in a normal state, this front side surface The rear side surface 26A of the locking projection 26 of the locking piece 25 is in contact with 38A from the front. On the other hand, the rear side surface of the holding projection 38, that is, the surface on the side facing the housing side guide surface 26B when the connector housing 20 is assembled, is a shell side guide surface 38B inclined upward.

Next, the operation and effect of the present embodiment configured as described above will be described.
A restriction window 36 is formed on the front side wall portion 34F of the shield shell 30, and the protrusion 24 of the connector housing 20 is fitted in each restriction window 36. At this time, the regulation surface 36A that is continuous with the lower surface of the regulation window 36 is in contact with the lower surface 24A of the projection 24 from below, and the projection 24 is restricted from being displaced downward.

Further, the shield shell 30 is provided with a holding projection 38, and the locking piece 25 of the connector housing 20 is locked to the holding projection 38. At this time, the rear side surface 26A of the locking projection 26 of the locking piece 25 is in contact with the front side surface 38A of the holding projection 38 from the front, and the connector housing 20 is rearward, that is, the projection 24 of the connector housing 20 is The displacement of the shield shell 30 in the direction away from the restriction window 36 is restricted. Thereby, it is avoided that the connector housing 20 is displaced backward in the accommodation space S, and the protrusion 24 is removed from the restricting window 36, and displacement restriction to the opening 35 side of the connector housing 20 is maintained.
Thus, the connector housing 20 is restricted from being displaced downward, that is, toward the opening 35 at the position of the protrusion 24.

In addition, a lead-out port 37 is formed in the rear side wall portion 34 </ b> R of the shield shell 30, and the electric wire 10 is led out from the lead-out port 37. At this time, the lower side surface 37 </ b> A of the peripheral surface forming the outlet 37 supports the electric wire 10 from the lower side, and the electric wire 10 is restricted from being displaced toward the opening 35. Here, since the rigidity of the electric wire 10 is relatively high, the displacement of the connector housing 20 toward the opening 35 can be restricted by restricting the displacement of the electric wire 10.
In this way, the connector housing 20 is restricted from being displaced toward the opening 35 at the position of the restricting window 36 and the position of the outlet 37 of the shield shell 30, that is, both the front and rear ends.

  As described above, according to the configuration of the present embodiment, the connector housing 20 is attached to the shield shell 30 only by assembling the connector housing 20 to the shield shell 30 without taking measures such as allocating the plate member to the opening 35. It can be prevented from being displaced to the side and thus coming off from the shield shell 30.

  Here, the assembly of the connector housing 20 to the shield shell 30 is performed as follows. FIG. 11 is a side sectional view showing a state where the connector housing 20 is assembled to the shield shell 30.

  First, the electric wire 10 is led out to the external space through the outlet 37 from the accommodation space S side of the shield shell 30. Next, the connector housing 20 is positioned so that the protrusion 24 of the connector housing 20 faces the restriction window 36 of the shield shell 30, and is in a posture that is horizontal with respect to the fitting direction of the protrusion 24 and the restriction window 36. To do. Here, the protrusion 24 has not yet been fitted into the restriction window 36, and the connector housing 20 is located in the housing space S at a position higher than the normal assembly position by the height of the protrusion 24. At this time, the locking projection 26 of the locking piece 25 is positioned behind the holding projection 27 of the shield shell 30, and is located behind the housing side guide surface 26 </ b> B and the holding projection 38 which are the front side surfaces of the locking projection 26. The shell side guide surface 38B, which is a side surface, faces the shell side guide surface 38B.

  Next, the connector housing 20 is advanced along the fitting direction. Then, the housing side guide surface 26B of the locking projection 26 comes into contact with the shell side guide surface 38B of the holding projection 38, and the locking projection 26 rides on the holding projection 38 while being guided by the shell side guide surface 38B. The locking piece 25 is elastically bent downward (in the direction intersecting with the fitting direction of the protrusion 24 and the restriction window 36).

  When the connector housing 20 is further advanced, the protrusion 24 is gradually fitted along the penetrating direction in the restriction window 36 (the fitting direction of the protrusion 24 and the restriction window 36). At the same time as the connector housing 20 reaches the normal position, the locking projection 26 gets over the holding projection 38 and the locking piece 25 is elastically restored, and the rear side surface 26A of the locking projection 26 is formed on the holding projection 38. The front side 38A is locked from the front. At this time, the front end surface of the connector housing 20 abuts against the inner peripheral surface of the shield shell 30 and the protrusion 24 and the restriction window 36 are fitted to each other, so that the connector housing 20 and the shield shell 30 are integrated. The shielded connector 1 is completed.

  Here, when the locking piece is not elastically deformable, when the locking piece comes into contact with the holding projection 38 during the advancement of the connector housing, the advancement may be hindered. For this reason, it is necessary to assemble in an oblique direction with the rear portion of the connector housing lowered so that the locking piece does not contact the holding projection 38. Then, the protrusion 24 must be fitted in an oblique direction with respect to the penetrating direction of the restricting window 36, and the assembling work becomes difficult. However, according to the configuration of the present embodiment, the locking piece 25 can be elastically bent in the crossing direction with respect to the fitting direction of the protrusion 24 and the restricting window 36, so that the locking piece 25 is held by the holding protrusion. When it comes into contact with 38, it bends and retracts in the crossing direction so as not to hinder the assembly work. Therefore, since the protruding portion 24 can be fitted along the penetration direction of the restricting window 36, the assembling work can be performed smoothly.

  Further, when the connector housing 20 is assembled to the shield shell 30, the opposing surfaces of the holding projection 38 and the locking projection 26 are the shell side guide surface 38 </ b> B and the housing side guide surface 26 </ b> B. Thereby, compared with the case where the guide surface is not provided in the mutually opposing surface, since this surface becomes difficult to catch, assembly | attachment operation | work can be performed more smoothly.

  Further, since the regulation window 36 penetrates the front side wall portion 34F of the shield shell 30 and communicates the accommodation space S and the external space, it can be seen that the projection 24 is fitted in the regulation window 36, The fitting state can be confirmed from the outside of the shield shell 30. Therefore, since the fitting state of the restriction window 36 and the protrusion 24 can be easily confirmed, the displacement restriction of the connector housing 20 toward the opening 35 can be made more reliable.

  Further, the protruding portion 24 is fitted into the restriction window 36 in a posture in which the protruding end protrudes forward from the front side wall portion 34F of the shield shell 30, that is, in a form penetrating from the accommodation space S of the shield shell 30 to the external space. Yes. As a result, the protrusion 24 is less likely to be removed from the restricting window 36 than when the protruding end reaches only the middle of the wall, so that the connector housing 20 is more reliably displaced toward the opening 35. Can be prevented.

  As described above, according to the present embodiment, the front side wall portion 34F of the shield shell 30 is provided with the restriction window 36 that restricts the displacement of the front end portion of the connector housing 20 toward the opening portion 35 side. The rear side wall portion 34R of the shield shell 30 is provided with a lead-out port 37 that restricts the electric wire 10 from being displaced toward the opening 35. Accordingly, the connector housing 20 is restricted from being displaced toward the opening 35 at both front and rear ends. Further, since the shield shell 30 is provided with a holding projection 38 that holds the fitting state of the regulation window 36 and the projection 24, the displacement regulation toward the opening 35 of the connector housing 20 is maintained. . Accordingly, it is possible to prevent the connector housing 20 from being displaced toward the opening 35 and thus coming off from the shield shell 30 while avoiding an increase in the number of parts and work processes.
