Description

[Detailed Description of the Invention] <Technical Field of the Invention> This invention relates to a cord clamp for a vehicle lamp. More specifically, the present invention relates to a cord clamp provided on a synthetic resin base such as a lamp body or a back cover of a vehicle lamp.

<Prior art and its problems> Rear combination lamps, which are generally installed on automobiles among vehicle lighting equipment, are equipped with multiple types of lighting equipment such as back clamps, tail and stop lamps, turn signal lamps, etc., and the light source bulbs of these lighting equipment are A large number of electric wire cords for supplying power to the lamp are arranged on the back of the lamp body and inside the back cover. If these many electric wire cords are not arranged in an orderly manner, they may get caught in other parts when the lamp is assembled, damaging the electric wire cords, causing shortcuts, or interfering with the assembly. Further, when taking things in and out of the trunk room, there is a danger that the electric wire cord may be caught and broken, making it impossible to turn on the light and causing an accident such as a rear-end collision.
Therefore, it has been conventional practice to provide a cord clamp on the lamp body or back cover, and to insert and hold the above-mentioned large number of electric wire cords into the cord clamp. The structure of such a conventional cord clamp is shown in FIG.

As shown in Figure A of the same figure, holding pieces b and c having hook-shaped cross sections are erected on a synthetic resin base a of the lamp body and back cover with their upper end protrusions facing each other. And the code e is the above-mentioned holding pieces b and c.
It passes through the gap between the upper end protrusions and is held in the space between the holding pieces b and c. Figure b in the same figure shows a cross section where the cord e is inserted into the gap between the upper end protrusions of the holding pieces b and c, and the gap width of the holding pieces b and c is somewhat narrower than the diameter L of the cord e. This prevents the cord e from slipping out of the holding space. Actually, the gap width is 1.5 mm for the diameter of cord e, which is 2.2 mm. Therefore, when the cord e is clamped to the holding pieces b and c, one cord from a bundle of five to eight cords is sequentially inserted into the holding pieces b and c.

However, when inserting multiple cords into a bundle into the holding piece one by one as described above, it is necessary to forcefully push each cord into the holding piece, and furthermore, the cords must be bundled in advance. The work of clamping the cord was complicated and time consuming, as it was necessary to position the vinyl tape so that the winding position did not overlap with the holding piece position.

<Purpose of the invention> This invention eliminates the drawbacks of conventional cord clamps as described above, and provides a cord clamp for vehicle lights that can easily clamp multiple cords in bundles and improves work efficiency. It is something to do.

<Structure of the invention> Therefore, in order to achieve the above purpose, the present invention has the following features:
In a cord clamp, holding pieces facing each other are provided on a base made of synthetic resin, sandwiching the cord placement position, and are provided with a claw for preventing the cable from coming off, which is connected to the upper end of the holding piece. This is a cord clamp for a vehicular lamp, in which a tab for opening and expanding is formed on a piece in the opposite direction to the claw.

<Embodiment of the invention> Next, an embodiment of the invention will be described with reference to FIGS. 1 to 5. FIG. 1 shows an overall perspective view of the cord clamp A, in which holding pieces 3 and 5 are placed on a base 1 made of flexible synthetic resin such as polypropylene, and are opposed to each other with the position where the cord 2 is to be placed in between. has been erected. As shown in the figure, one of the holding pieces 3 is provided with a claw 31 at the upper end for preventing the cord 2 from coming off, and a knob 4 facing oppositely to the claw 31. This knob piece 4 is formed to be inclined upward. Note that the through hole 6 shown directly below the knob piece 4 is created by punching out the mold when molding the knob piece 4. The other holding piece 5 is provided with a claw 51 facing the claw 31. These claws 31 and 51 are opposed to each other with a gap slightly narrower than the diameter of the cord 2 to prevent the cord 2 from slipping out from this gap. In addition, a rib 52 is provided on the back surface of the holding piece 5 so that the cord 2
This prevents bending during insertion.

To insert the cord 2 into the clamp A, as shown in FIG. 2, push down the knob 4 provided on the holding piece 3 in the direction of the arrow P shown in the figure with your finger 7, and the holding piece 3 will have appropriate flexibility. Deflects from. Then, the gap between the claws 31 and 51 is widened and the code 2 is connected to the arrow T shown in the figure.

direction and returns to the original position again, maintaining the gap between the claws 31 and 51 in the original state, and preventing the cord 2 from slipping out. In this way, the present invention takes advantage of the flexibility of the synthetic resin material to widen the gap between the claw pieces 31 and 51 by pushing down the knob piece 4 provided on one of the holding pieces 3, thereby tightening the cord. 2, it is possible to easily insert even a bundle of 5 to 8 cords 2. Moreover, by releasing the knob 4, the cord 2 will not slip out.

FIG. 4 shows a modification of the holding piece 5.
A claw piece 5b is provided on the partition wall 5a between the light chambers as shown in the figure, and the insertion of the cord 2 in this case is the same as described above.

FIG. 5 shows an example in which the cord clamp A of the present invention is applied to a back cover 10 of a vehicle lamp, in which a socket holder 8 is attached to the back cover 10.
a, 8b are integrally provided in a protruding manner, and light source bulbs 9, 9 are inserted into these socket holders 8a, 8b.
A plurality of cords 2, 2 coming out from the socket holders 8a, 8b are fixed to the cord clamp A in a bundled state.

<Effects of the invention> As detailed above, since the cord clamp for the vehicle lamp of the present invention is constructed as described above, it is not necessary to insert multiple cords one by one into the holding piece as in the conventional case. By being able to easily insert the cords in a bundle without having to do anything, and by being able to insert the cords regardless of the wrapping position of the vinyl tape that makes the cords into a bundle, the work efficiency of cord assembly is significantly improved, and the cords do not come out easily. It has remarkable effects such as being able to prevent
