Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicular lamp, and more specifically, to an improvement in a connection structure for connecting a plurality of lamp sockets using all earth cords.

Conventionally, in a vehicle lamp equipped with a plurality of lamps such as a rear combination rung, a ground cord b is wired to each rung socket a, as shown in Figs. 1 and 2. , a core wire attachment portion d is formed on the terminal C fixed to the lamp socket a, and one end of the core wire attachment portion d and the core wire attachment portion d of the terminal adjacent thereto.
Connect the ground cord BK to the other end of each terminal C.
The ground cord b'6 is wired between them. To connect the ground cord bi to the core wire attachment part d, the connection is made by manually crimping using a single-action crimping machine.

Note that f is a screw for fixing terminal c to a when the lamp is fully installed.

By the way, in conventional vehicle lights, the ground cord B6 is wired between the terminal C and the terminal C provided in the socket A, so when assembling, the ground cord B6 is wired between the terminals C and B6. Since it has to be cut into multiple pieces according to the dimensions, and the sheathing at both ends of each earth cord 5 must be stripped to expose the entire core wire,
The problem is that it takes a lot of time. Also, the terminal
Since two ground cords (b) are fully connected for each individual, the number of man-hours required for connection increases, and since it is necessary to bundle each core wire one by one during connection work, it is difficult to perform connection work. Moreover, since the connection work is performed manually using a single-movement clasp, variations in quality are likely to occur. Furthermore, as the number of lamps and rung sockets a increases, terminal C
Not only does this increase, but the number of earth cords b also increases, which has the disadvantage of further increasing the number of cutting and connecting steps.

In view of the above circumstances, the present invention provides an earth cord 2z-10
It is an object of the present invention to provide a vehicular lamp which is composed of a book, and which can easily connect an earth cord and a terminal, thereby improving quality and reducing costs.

The details of the present invention will be explained below with reference to FIGS. 3 to 7. 3 to 7 show an embodiment of a vehicle lamp according to the present invention.

The vehicle lamp according to the present invention has a plurality of lamp sockets 1 to which lamps (not shown) are to be mounted, a terminal 2 is arranged in each lamp socket 1, and one earth cord 3 is connected to each terminal 2. That is, each of the terminals 2 is made of a processed conductive metal plate, and is formed integrally with the flat plate 21, as shown in FIG. 4, and has a screw insertion hole 23. It can be fixed to each lamp socket 1 with a screw 4 passing through the screw insertion hole 23. Further, each terminal 2 is formed with a core wire holding portion 24 for connecting the earth cord 3. The core wire holding part row is curved in an iU shape with an extension piece 24b formed as an extension and a cutout piece 24c formed on opposite edges of the one end 24a of the flat plate 21, and a ground cord is inserted between the two. 3 core wire exposed part 3
1. By inserting and caulking the extension piece 271b
The core wire exposed portion 31 can be held by both the cutout piece 24c and the cutout piece 24c. The core wire exposed portion 31 is
The core wires of the earth cord 3 are exposed by removing the covering portions at positions corresponding to the respective terminals 2. Therefore, by holding the core wire exposed portion 31 in the core wire holding portion U, the grounding cord 3 can be connected to each lamp socket 1. In order to facilitate connection, the width 1 is slightly larger than the width of the core wire holding portion U. In addition, in order to actually connect the ground cord 3 and each socket 1, connect the terminal 2 to the core wire exposed part 31 of the ground cord 3 in advance, and fix the terminal 2 to the socket 1 with the full screw 4. . 5 is the main terminal.

As described above, in the vehicle lamp according to the present invention, one core wire holding portion 24 is provided on the terminal 2 disposed in each lamp socket 1, and each core wire holding portion row exposes the core wire of the ground cord 3. Since the portion 31 is held, the ground cord 3 can be configured as a single piece.

As a result, compared to the conventional method, it is not necessary to cut the earth cord into multiple pieces, so the cutting man-hours can be greatly reduced, and the entire covered part of only one earth cord 3 can be stripped. This makes it possible to automate the stripping process. Further, since each terminal 2 is provided with only one core wire holding portion 24, the connection work between each terminal 2 and the earth cord 3 can be performed by a single caulking process. In that case, the core wire exposed portion 31 provided in the middle of the earth cord 3 is different from the core wire exposed portion 31 provided at the end.
Since the core wires are bundled together, there is no need to bundle the core wires individually during caulking, so the caulking process can be performed smoothly, and it is also possible to automate the caulking process, minimizing variations in quality. I can do it.

Furthermore, if the number of lamps and lamp sockets 1 increases, the number of terminals 2 will also increase, and the length of the earth cord 3 will have to be changed accordingly and an exposed core portion 31 will have to be provided. As a result, an increase in the number of lamps by one lamp requires only one additional step of connecting the ground cord 3 and the terminal 2, so it can be easily handled.

Although the illustrated embodiment shows an example in which the terminal 2 is fixed to the rung socket 1 with the screw 4, the present invention is not necessarily limited to fixing with screws, and, for example, the terminal may be fixed to the rung socket 1. It can also be applied to those that are inserted into and engaged with each other, or those that are integrally formed.

As described above, according to the present invention, one core wire holding portion is formed in each terminal provided in each lamp socket, and each core wire holding portion is provided with a core wire holding portion for a single earth cord. Since each rung socket and the ground cord can be connected by holding the parts together, the connection between the ground cord and the terminal can be completed by caulking only once, compared to the conventional method. Since the core wire exposed part in the middle of the ground cord is gathered together and there is no need to bundle it, the crimping process can be performed completely smoothly, and the crimping process can be automated.・Variations in quality are minimized. quality can be improved.
