Description

{locking structure of wiring connector}

The present invention relates to a wiring connector fixing structure, and more specifically, to a wiring connector fixing structure capable of fixing a wiring connector that electrically connects different wirings to a vehicle.

Unless otherwise indicated herein, the matters described in this identifier are not prior art to the claims of this application, and their description in this identifier is not intended to be an admission that they are prior art.

In order to connect circuits composed of parts used in automobiles, wiring connectors can be used. The wiring connector is installed at the end of the wiring and electrically connects between the wirings or between the wirings. Such a wiring connector can be fixed to the vehicle via a wiring clip. Fig. 1 is a perspective view illustrating a conventional wiring connector and a wiring clip. As illustrated in Fig. 1, the wiring clip and the wiring connector can be fastened to each other as the formed protrusion of the wiring clip and the formed protrusion of the wiring connector are caught with each other.

However, since the direction in which the conventional wiring clip is inserted into the wiring connector is limited, if another component is located on the side where the insertion starts or the wiring connector is placed in a position where it is difficult to insert the wiring clip, the fastening work becomes difficult. In addition, after the wiring clip and the wiring connector are fastened, if a separation work to release the fastening is required, the worker must use a removal tool to separate the wiring clip and the wiring connector. Using a tool to separate the wiring clip and the wiring connector is disadvantageous in terms of workability compared to quickly separating them by hand.

Therefore, industrial sites require technology related to wiring connectors that can improve the efficiency of connecting and disconnecting operations of wiring connectors.

Republic of Korea Patent No. 10-2204446 (announced on January 19, 2021) Republic of Korea Utility Model Registration No. 20-0438134 (Public Notice 2008.01.22)

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wiring connector fixing structure capable of easily fixing a wiring connector and easily releasing the fixed wiring connector.

In order to solve the above problems, the present invention proposes a wiring connector fixing structure that connects a counterpart installed in a vehicle and a wiring connector that electrically connects different wiring, the wiring connector fixing structure comprising: a support portion that extends to a predetermined length and protrudes from one surface of an outer surface of the wiring connector; and a plate portion that includes a cantilever that extends from the support portion and is formed to have a cross-section larger than a cross-section of the support portion, and is formed radially by being cut at predetermined angles around a central axis penetrating the support portion on a peripheral surface; wherein the cantilever portion is detachably coupled to the counterpart.

In addition, the cantilever beam may have sliding grooves formed in the longitudinal direction on the outer surface facing the counterpart, and engaging protrusions may be formed on the basic surface and one of the two side surfaces forming the sliding groove, respectively, and the basic surface.

In addition, on another surface among the outer surfaces of the wiring connector, the support portion, the plate portion and the cantilever or the coupling portion of the counterpart detachably coupled with the cantilever may be selectively formed in the same shape.

In addition, the wiring connector fixing structure is characterized in that the connecting portion includes a pair of guide walls formed in a wall shape that are spaced apart from each other and face each other in a parallel manner, a cover wall extending from one end of the guide wall toward the other guide wall, and a catch stopper that is protruded on a central surface portion between the pair of guide walls and catches on the catch.

Meanwhile, in a wiring connector fixing structure that connects a counterpart installed in a vehicle and a wiring connector that electrically connects different wiring, the wiring connector fixing structure comprises: a support portion that extends to a predetermined length and is formed protrudingly on one side of an outer surface of the counterpart; a plate portion that extends to the support portion and is formed to have a cross-section larger than a cross-section of the support portion, and includes a cantilever that is formed radially by being cut at predetermined angles around a central axis passing through the support portion on the circumferential surface; and the cantilever portion can be detachably connected to the wiring connector.

In addition, the cantilever beam may have sliding grooves formed in the longitudinal direction on the outer surface facing the wiring connector, and engaging protrusions may be formed on the basic surface and one of the two side surfaces forming the sliding groove, respectively, and the basic surface.

In addition, the support portion, the plate portion and the cantilever or the connecting portion of the wiring connector detachably connected to the cantilever may be selectively formed in the same shape on another surface among the outer surfaces of the counterpart.

In addition, the above-mentioned hanging cantilever can be elastically hinge-rotated about the fixed end by an external force applied to the free end.

Additionally, a reinforcing rib may be formed protruding on the outer surface of the fixed end of the above-mentioned hanging cantilever.

Additionally, the counterpart may be a wiring clip including an anchor portion that is inserted into and fixed in an anchor hole formed in the vehicle.

Additionally, the counterpart may be a wiring harness protector that accommodates and protects a wiring harness in which a plurality of wires are bundled together.

According to the problem-solving means of the present invention as examined above, various effects including the following can be expected. However, the present invention is not established only when all of the following effects are exhibited.

First, the present invention can improve workability by allowing the wiring connector to be easily combined and separated with a counterpart such as a wiring clip.

In addition, the present invention can significantly reduce the possibility of damage to the wiring connector or the counterpart when the wiring connector and the counterpart are separated.

In addition, the present invention can accommodate various paths of wiring connected to a wiring connector by allowing the coupling angle between a counterpart or other wiring connectors to be adjusted to various angles.

As shown in these drawings, the wiring connector (CN) fixing structure (10) of the present invention relates to a wiring connector (CN) fixing structure (10) that can fix a wiring connector (CN) that electrically connects different wirings to a vehicle. The wiring connector (CN) fixing structure (10) of the present invention includes a support portion (100) and a plate portion (200). Specifically, the support portion (100) is formed to protrude and extend to a predetermined length on one side of an outer surface of the wiring connector (CN). The plate portion (200) is formed to extend to the support portion (100) and have a cross-section larger than the cross-section of the support portion (100), and includes a cantilever (220) that is formed radially by being cut at predetermined angles around a central axis (CA) passing through the support portion (100) on the circumferential surface. In addition, the cantilever (220) can be detachably coupled to a counterpart (CP). Here, the counterpart (CP) refers to a component that is installed in a vehicle and connected to a wiring connector (CN). Examples of the counterpart (CP) include a wiring clip that includes an anchor portion that is inserted and fixed into an anchor hole formed in a vehicle, and a wiring harness protector that accommodates and protects a wiring harness in which a plurality of wirings are bundled together. The counterpart (CP) is not limited to a wiring clip or a wiring harness protector, and may be various types of components that are installed in a vehicle and fix a wiring harness. Each component will be described in detail below.

The support member (100) may be formed on the outer surface of the wiring connector (CN). The support member (100) may be formed to protrude and extend to a predetermined length on one side of the outer surface of the wiring connector (CN). The support member (100) may be formed integrally with the wiring connector (CN) from the same material. Since the wiring connector (CN) is generally manufactured from a synthetic resin material, the support member (100) may also be formed from the same material.

The plate portion (200) formed by extending to the support portion (100) is formed to have a cross-section larger than the cross-section of the support portion (100). The plate portion (200) may be formed integrally with the support portion (100) using the same material. The support portion (100) may be formed in a plate shape having a predetermined thickness. The support portion (100) may be formed in a circular or polygonal plate shape, but is preferably formed in a polygonal plate shape. When the plate portion (200) is formed in a polygonal plate shape, the end surface of the free end of the cantilever (220) included in the plate portion (200) becomes flat, so that the area where the cantilever (220) is caught or comes into contact with the cover wall (320) of the coupling portion (300) described later becomes larger, thereby increasing the coupling force between the cantilever (220) and the coupling portion (300).

The plate portion (200) can be cut at predetermined angles around a central axis (CA) that penetrates the support portion (100) on the circumferential surface. The central axis (CA) penetrates the support portion (100) and the plate portion (200). That is, cut portions (210) can be formed at predetermined angles around the central axis (CA) that penetrates the upper and lower surfaces of the plate portion (200). As the cut portions (210) are formed in the plate portion (200), cantilever beams (220) can be formed at predetermined angles.

A cantilever (220) detachably coupled with a counterpart (CP) has a fixed end and a free end, and is formed in multiple pieces centered on a central axis (CA). The cantilever (220) is formed radially with respect to the central axis (CA). As illustrated in (c) of FIGS. 9 and 10, the multiple cantilever (220) enables the counterpart (CP) to be coupled with the wiring connector (CN) at various angles with respect to the central axis (CA). That is, the multiple cantilever (220) enables the coupling angle at which the counterpart (CP) and the wiring connector (CN) are coupled to be adjustable. The coupling angle can become more diverse as the number of cantilever (220) increases. However, since the cross-sectional area of the fixed end of the cantilever (220) generally decreases as the number of cantilever (220) increases, the possibility of the fixed end of the cantilever (220) being broken can increase. Therefore, in order to prevent breakage of the cantilever beam (220) and ensure a certain degree of freedom in the coupling angle, it is preferable to provide eight cantilever beams (220) arranged at 45-degree intervals.

The cantilever (220) has one fixed end and the other free end, so that when an external force is applied to the free end, it can be hinge-rotated elastically. Since the cantilever (220) itself has elastic properties, it can be hinge-rotated around the fixed end. When the external force is removed from the free end of the cantilever (220), it can be restored to its original state. As illustrated in FIG. 11, when an external force is applied to the free end of the cantilever (220) and the cantilever (220) is hinge-rotated, the engagement state between the engagement step (223) of the cantilever (220) and the engagement stopper (330) of the joint (300), which will be described later, can be released. However, when an external force is applied to the free end of the cantilever (220), stress is concentrated on the fixed end of the cantilever (220), and there is a risk that the fixed end may be broken. Accordingly, a reinforcing rib (225) can be formed protrudingly on the outer surface of the fixed end of the cantilever beam (220). The outer surface on which the reinforcing rib (225) is formed is the surface opposite to the surface on which the sliding groove (221) is formed, and is the surface facing the support member (100). The reinforcing rib (225) can reduce the possibility of the fixed end of the cantilever beam (220) being broken.

The cantilever (220) is slidably inserted into the space formed by the guide wall (310) and the cover wall (320) of the counterpart (CP) to be described later, and a pair of cantilever (220) positioned symmetrically, i.e., oppositely, with respect to the central axis (CA) can be caught on the catch stopper (330) to be described later. The cantilever (220) can have a sliding groove (221) formed along the longitudinal direction on the outer surface facing the counterpart (CP). Since the sliding groove (221) is formed on each cantilever (220), they are connected to each other at a portion passing through the central axis (CA) of the plate portion (200). As shown in FIGS. 7 and 8, due to the communicating portion of the sliding groove (221), when the cantilever (220) is slidably inserted into the outer surface of the counterpart (CP), the cantilever (220) can be slidably inserted without being caught by the catch stopper (330) until it is completely fixed to the connecting portion (300) of the counterpart (CP).

A catch (223) may be formed by protruding from the basic surface (221a) of the sliding groove (221). The sliding groove (221) may be formed of a basic surface (221a) and two side surfaces (221b). The two side surfaces (221b) are two side surfaces connected to both edges of the basic surface (221a). The catch (223) is a portion that catches the catch stopper (330) of the connecting portion (300) to be described later. The surface of the catch stopper (223) facing the outside of the sliding groove (221) may be formed to be inclined. The catch stopper (223) with the inclined surface (223a) formed can easily ride over the catch stopper (330) with the inclined surface (330a) formed later. This will be described later. It is preferable that the catch (223) be formed at a position adjacent to the free end of the cantilever (220) on the base surface (221a) of the sliding groove (221). When the catch (223) is formed at a position adjacent to the free end of the cantilever (220), when an external force is applied to the free end of the cantilever (220) to release the engaging state of the catch (223) and the engaging stopper (330), the hinge rotation angle of the cantilever (220) required to release the engaging state of the catch (223) and the engaging stopper (330) can be minimized. Since the size of the external force to release the engaging state of the catch (223) and the engaging stopper (330) is also minimized, a worker can easily release the engaging state of the catch (223) and the engaging stopper (330) with a small force.

The aforementioned support portion (100), plate portion (200), cantilever (220), and coupling portion (300) may be selectively formed in the same shape on other surfaces of the outer surface of the wiring connector (CN). As illustrated in FIG. 10, multiple support portions (100), plate portions (200), cantilever (220), and coupling portions (300) may be formed on multiple surfaces of the wiring connector (CN). In this case, the counterpart (CP) on which the coupling portion (300) is formed may be selectively coupled to the cantilever (220) formed on any one of the multiple surfaces of the wiring connector (CN). In other words, the degree of freedom of coupling between the counterpart (CP) and the wiring connector (CN) may be increased.

In addition, when the coupling portion (300) is formed in the wiring connector (CN), the wiring connector (CN) on which the coupling portion (300) is formed and another wiring connector (CN) on which the support portion (100), the plate portion (200), and the cantilever (220) are formed can be coupled to each other. In addition, a counterpart (CP) on which the support portion (100), the plate portion (200), and the cantilever (220) described later are formed can be detachably coupled to the coupling portion (300) of the wiring.

The joint (300) formed on the counterpart (CP) is a portion that is joined to the cantilever (220). As illustrated in FIG. 4, the joint (300) may include a guide wall (310), a cover wall (320), and a catch stopper (330). The guide walls (310) are formed as a pair, and may be formed in a wall shape that is spaced apart from each other and faces each other in parallel. The distance at which the pair of guide walls (310) are spaced apart from each other is preferably equal to or slightly smaller than the distance between the end faces of the free ends of the pair of cantilever beams (220), in terms of ease of joining and joining force between the cantilever beam (220) and the joint (300). The cover wall (320) may be formed to extend from one end of the guide wall (310) toward the other guide wall (310). The cover wall (320) covers the cantilever (220) and can prevent the cantilever (220) from being detached. The cantilever (220) can be slidably inserted into the space formed by the guide wall (310) and the cover wall (320). The catch stopper (330) can be formed to protrude on the central surface portion between the pair of guide walls (310). The catch stoppers (330) can be formed as a pair so that they can be caught on the catch protrusions (223) of the pair of cantilever beams (220). The pair of catch stoppers (330) can be caught on each of the pair of catch protrusions (223). In addition, the catch stoppers (330) can be formed so that the surfaces facing each other are inclined. As shown in FIGS. 7 and 8, when the cantilever (220) is slidably inserted into the joint (300), the catch step (223) formed with the inclined surface (223a) can easily pass over the catch stopper (330) formed with the inclined surface (330a). When the catch step (223) passes over the inclined surface (330a) of the catch stopper (330), the cantilever (220) is elastically deformed and hinge-rotated around the fixed end, and when the catch step (223) completely passes over the catch stopper (330), the cantilever (220) can be elastically recovered and restored to its original state.

As illustrated in FIG. 5, the plate portion (200) including the support portion (100) and the cantilever (220) formed on the aforementioned wiring connector (CN) can be formed in the same shape as the counterpart (CP). At the same time, the joining portion (300) including the guide wall (310), the cover wall (320), and the catch stopper (330) of the aforementioned counterpart (CP) can be formed in the same shape as the wiring connector (CN). In this case as well, the aforementioned contents are equally applicable, so a detailed description thereof will be omitted.

As described above, the counterpart (CP) can be a wiring clip, a wiring harness protector, etc. In FIG. 6, FIG. 7, FIG. 10, etc., it can be seen that the counterpart (CP) is formed as a wiring clip or a wiring harness protector.

As seen above, the wiring connector (CN) fixing structure (10) of the present invention can improve workability by allowing the wiring connector (CN) to be easily coupled and separated from a counterpart (CP) such as a wiring clip. In addition, the present invention can significantly reduce the possibility of damage to the wiring connector (CN) or the counterpart (CP) when the wiring connector (CN) and the counterpart (CP) are separated. In addition, the present invention can adjust the coupling angle between the counterpart (CP) coupled to a certain wiring connector (CN) or another wiring connector (CN) to various angles, thereby enabling the invention to respond to various paths of wiring connected to the wiring connector (CN).
