Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vehicular lamp in which a housing is provided with a harness holding plate for holding a harness for supplying electric power to a lamp.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a harness holding plate 4 for holding a tubular harness 3 in which a plurality of cords 3'for supplying electric power to a bulb (lamp) 2 are bundled together is synthesized. 2. Description of the Related Art A vehicular lamp integrally formed with a resin housing 1 is known. Reference numeral 5 is a valve 2
It is a socket for mounting. As shown in FIG. 4, the harness holding plate 4 of this type of vehicle lamp has a harness holding hole 6 formed through the plate in the plate thickness direction, and a harness holding plate 4 facing the harness holding hole 6 from the side surface of the harness holding plate 4. It is provided with opposed peripheral walls 8 and 9 that face each other with a guide space 7 interposed therebetween. The facing wall surfaces of the facing peripheral walls 8 and 9 are tapered surfaces 8a and 9a in which the distance between the wall surfaces in the guide space 7 is narrower toward the harness holding hole 6 and the minimum clearance is smaller than the diameter of the harness 3. Has been done. In the harness holding plate 4 having such a configuration, by pushing the harness 3 from above the guide space 7, the opposing peripheral walls 8 and 9 are forcibly expanded in the arrow X direction in the drawing, and the harness 3 is held in the harness holding hole. It is fitted in 6 and facing peripheral walls 8 and 9
Returns to the original posture and the harness 3 is held.

[0003]

However, in the harness holding plate 4 of this type, a structure that alleviates the internal stress generated when the opposing peripheral walls 8 and 9 are forcedly expanded in the X direction, in other words, positively, is positively applied. It does not have a structure that causes bending. Therefore, when the wall thickness A of the harness holding plate 4 is reduced so that the opposing peripheral walls 8 and 9 are bent, a bending stress mainly concentrates and cracks are generated in the vicinity of both side portions C of the harness holding hole 6 having low strength, and the cracks face each other. There is a problem that the peripheral walls 8 and 9 may be broken. In addition, the opposing peripheral wall 8,
If the wall thickness A of 9 is not broken, the bending of the opposing peripheral walls 8 and 9 is reduced, and the tapered surfaces 8a and
There has been a problem that the minimum gap B between the 9a has to be increased and the harness 3 is easily pulled out.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicular lamp capable of securely holding the harness and preventing the harness from coming off while avoiding damage to the harness holding plate. I am trying.

[0005]

In order to achieve the above object, the invention according to claim 1 is for a vehicle in which a housing is provided with a harness holding plate for holding a harness for supplying electric power to a lamp. In the lamp, the harness holding plate has a harness holding hole penetratingly formed in a plate thickness direction,
A side wall of the harness holding plate and a facing peripheral wall facing each other with a guide space sandwiching the guide space guiding the harness toward the harness holding hole, and the facing peripheral wall has a wall surface facing the guide space facing the harness holding hole. The distance between each other is narrowed and the minimum gap is made smaller than the diameter of the harness to form a tapered surface, and one of the opposing peripheral walls has a cutting space so as to bend when being pushed into the harness holding hole from the guide space. The flexible piece is characterized in that it returns when the harness is fitted into the harness holding hole.

According to the first aspect of the invention, the internal stress generated when the harness is pushed into the guide space and the opposite peripheral wall is expanded is relieved by the bending of the flexible piece. Then, this flexible piece functions as a member for preventing the harness from slipping out of the harness holding hole.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a bottom view showing an embodiment of the vehicular lamp of the present invention. A housing 11 made of synthetic resin is provided with lamp mounting portions 12 and 13 for mounting a lamp. Below the lamp mounting portion 12, a harness holding plate 14 that holds the harness 3 (see FIG. 3) for supplying electric power to the lamp is provided integrally with the housing 11.

As shown in FIG. 1 (B), the harness holding plate 14 has a harness holding hole 15 formed through the same cylindrical shape as the harness 3 in the plate thickness direction, and a harness 3 from the side surface of the harness holding plate 14. Opposing peripheral walls 17 and 1 that face each other with a guide space 16 that guides the harness toward the harness holding hole 15 interposed therebetween.
8 is provided. Opposing peripheral walls 17 and 18 are guide spaces 16
Further, the wall surface side is tapered toward the harness holding hole 15, and the minimum clearance is tapered surfaces 17a and 18a whose diameter is smaller than the diameter of the harness 3.

One of the opposing peripheral walls 17 is formed with a cutting space 19 so as to bend when the harness 3 is pushed into the harness holding hole 15 from the guide space 16, and bends as shown by a chain double-dashed line in FIG. 1 (A). It is a flexible piece that can be.
As shown by the solid line in FIG. 1 (A), this flexible piece slides the harness 3 on the tapered surface 18a while the harness holding hole 1
The size is set so that the harness 17 is restored when it is fitted in the connector 5, and the tip portion 17b thereof presses the harness 3. The excision space 19 is such that, when the harness 3 is pushed from the guide space 16 and fitted into the harness holding hole 15, the flexible piece (opposing peripheral wall) 17 is bent and a range where the above-mentioned return can be secured. Of course, the diameter of the harness 3 and the size of the harness holding plate 14 are appropriately designed.

According to the vehicular lamp including the harness holding plate 14 having such a structure, the internal stress generated when the harness 3 is pushed into the guide space 16 and the opposite peripheral walls 17 and 18 are expanded, the flexible piece. It is relieved by the bending of. Moreover, since only the opposing peripheral wall 17 is made a flexible piece and the opposing peripheral wall 18 is made less likely to bend than the opposing peripheral wall 17, the opposing peripheral wall 1
The taper surface 18a of 8 can be used as a reference surface for pushing the harness 3 in sliding contact therewith, and the harness 3 can be used as a reference surface.
If the inner peripheral wall 17 is pushed in while being pressed toward the eight side, the opposing peripheral wall 17 can be prevented from being damaged without being bent excessively.

Further, this flexible piece has a harness holding hole 15
It functions as a member for preventing the harness 3 fitted into the connector from coming off. Further, by the prevention of the slip-out, it is possible to prevent the cord from being bitten with time between the vehicle lamp and the vehicle body panel.

In this embodiment, the harness holding hole has a columnar shape, but it may have a prismatic shape which is aligned with the shape of the harness. Further, although the opening of the guide space is provided in the upper surface portion of the harness holding plate, it may be provided in the side surface portion of the harness holding plate due to the relationship with the wiring and the like. Furthermore, it is also possible to push the respective cords one by one, instead of grouping the plural cords together.

[0014]

As described above, according to the present invention, the internal stress generated when the harness is pushed into the guide space and the opposing peripheral wall is expanded is relieved by the bending of the flexible piece, and the flexible piece is relaxed. Functions as a member for preventing the harness from slipping out of the harness holding hole, so that the harness holding plate is prevented from being damaged and the harness is securely held to prevent the harness from slipping out. It is possible to prevent the generated cord from being caught.
