Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a vehicle lamp, and more specifically, to an improvement in a connection structure for connecting a plurality of lamp sockets with a ground cord.

[Background of the invention]

Conventionally, in a vehicle lamp equipped with a plurality of lamps such as a rear combination lamp, an earth cord B is wired to each lamp socket A, as shown in FIGS. 1 and 2, for example. A core wire attachment portion d is formed on a terminal c fixed to a lamp socket a, and an earth cord b is connected to one end of the core wire attachment portion d and the other end of the core wire attachment portion d of the adjacent terminal. Earth cords b are wired between terminals c. The ground cord b is connected to the core wire attachment portion d by manual crimping using a single-action crimping machine. Note that f is a screw for fixing terminal c to lamp socket a.

By the way, in conventional vehicle lamps, the ground cord b is wired between the terminal c and the terminal c provided in the lamp socket a, so when assembling the ground cord b, the dimension between the terminals c and It is necessary to cut a plurality of wires according to the size of the wire, and each ground cord b must be stripped to expose the core wire, which is a time-consuming problem. In addition, since two earth cords b are connected to each terminal, the number of man-hours required for connection increases, and it is difficult to perform the connection work since it is necessary to bundle each core wire one by one. Moreover, since the connection work is performed manually using a single-movement clasp, quality is likely to vary. Furthermore, as the number of lamps and lamp sockets a increases, not only the number of terminals c increases, but also the number of ground cords b, which increases the number of cutting and connecting steps.

In view of the above-mentioned circumstances, the applicant constructed a single earth cord for connecting each lamp socket, attached a terminal made of a metal plate to each lamp socket, and provided the terminal with cut and raised pieces facing each other. to form a core holding part of the ground cord, and the ground cord forms a core exposed part by removing the covering at a position corresponding to the core wire holding part of each terminal, and the exposed core part is connected to the core wire of the terminal. A patent is pending for a solution to the above-mentioned problem by caulking the holding part, but if this is done, the ground cord will move around each terminal as a fulcrum due to vibrations during vehicle operation, and the exposed core wire will be damaged. I learned that there is a risk of wire breakage at the core wire holding part.

[Purpose of the invention]

The present invention further improves the conventional vehicle lighting device as described above, and makes it possible to easily connect the ground cord to each terminal, while eliminating the risk of the ground cord breaking at each terminal due to vibrations during vehicle operation. The purpose of this invention is to provide a vehicle lighting device that does not cause any nuisance.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention includes a core wire holding part and a cord holding part that can hold the core wire of the earth cord and the coated cords on both sides of the core wire by caulking. and the ground cord is composed of one piece,
A core wire exposed portion from which the covering portion has been removed is provided at a position corresponding to the core wire holding portion in each terminal of the ground cord, and the core wire exposed portion has a length that can be inserted into the core wire holding portion, and the core wire exposed portion and the covering on both sides thereof are provided. The cord is held by the core wire holding part and the cord holding part by caulking.

[Embodiments of the invention]

Next, one embodiment of the present invention will be described with reference to FIGS. 3 to 5.

3 to 5 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 disposed in each of the lamp sockets 1, and a single earth cord 3 is connected to each terminal 2. are doing.

That is, the terminal 2 is
As shown in the figure, it is a flat plate made of a conductive metal plate and has a screw insertion hole 21 on one side, and is connected to each lamp socket 1 by a screw 4 passing through the screw insertion hole 21. It can be fixed. Also, at one end of each terminal 2, there is a core wire holding part 2 for connecting the ground cord 3.
2, and cord holding portions 23 on both the left and right sides thereof. The core wire holding part 22 is formed by curving into a U-shape holding pieces 22b and 22c extending from opposing edges of the end edge part 22a of the terminal, and the cord holding part 23 is formed by curving into a U-shape. Core wire holding part 2
Holding pieces 23b and 23c formed slightly longer than the core wire holding portion 22 by separating the intervals on both sides of the
It is formed by curving it into a letter shape. This core wire holding part 22
The core wire exposed portion 3a of the earth cord 3 is positioned between them, and the core wire 3a is caulked as shown in FIG.

The core wire exposed portion 3a exposes the core wire by removing the covering portion of the earth cord 3 at a position corresponding to each terminal 2. Further, the exposed core portion 3a has a width slightly larger than the width of the core wire holding portion 22 in order to facilitate positioning and connection. To actually connect the ground cord 3 and each socket 1, first swage the exposed core wire 3a of the ground cord 3 and the covering parts 3b on both sides to the terminal 2, and then attach the terminal 2 with the screw 4.
Fix it to socket 1 with.

As described above, the vehicle lamp according to the present invention has a terminal 2 disposed in each lamp socket 1;
One core wire holding portion 22 and cord holding portions 23 on both sides thereof are provided, and the core wire holding portion 22 and cord holding portions 23 cover the exposed core portion 3a of the earth cord and the adjacent earth cord. Compared to the conventional one, since the covering parts on both sides of the exposed core wire are supported by the cord holding part 23, they do not move and the earth cord is not likely to break at the terminal. do not have. Furthermore, since it is no longer necessary to cut the earth cord 3 into multiple pieces, the number of cutting steps can be greatly reduced, and since the covering portion of only one earth cord 3 is stripped, the stripping work can be automated. becomes possible. Also, the core wire exposed portion 3a of this earth cord 3
Unlike conventional wires that are attached to the ends, the core wires are bundled together and there is no need to bundle the core wires each time during caulking, making it possible to perform the caulking process smoothly and to automate the caulking process. This makes it possible to reduce variations in quality.

Furthermore, if the number of lamps and lamp sockets increases, the number of terminals 2 will also increase.
The length of the earth cord 3 can be changed accordingly, and this makes it easy to cope with the increase in the number of lamps, since the connection work between the earth cord 3 and the terminal 2 only increases by one step. be able to.

Although the illustrated embodiment shows an example in which the terminal 2 is fixed to the lamp socket 1 with the screw 4, the present invention is not necessarily limited to fixing with the screw. For example, the terminal may be inserted into the lamp socket. It can be applied to things that are engaged or integrally formed.

In the above embodiment, when the width of each terminal 2 is wide, it is possible to provide the core wire holding part 22 and the cord holding part 23 at an appropriate distance as described above. If the dimensions are narrow, the core wire holding part 22 and the cord holding part 23 may not be provided as shown in FIGS. 4 and 5. In such a case, as shown in FIGS. 6 and 7, a core wire holding part 22 consisting of holding pieces 22b and 22c is formed on both sides of the approximate center of the end edge 22a of the terminal, and the terminal The cord holding part 24 may be formed by providing one extension piece 23d having a length capable of holding the cord 3 at the outer end thereof.

〔Effect of the invention〕

As detailed above, the vehicle lamp of the present invention has
Since a core wire holding part and a cord holding part are formed at each terminal of a plurality of lamp sockets, and a single earth cord is used to connect each terminal, the work of connecting each terminal is simplified. In addition, since the coated cords on both sides of the core wire holding portion of each terminal are held by the cord holding portions, there is no risk of the exposed core wire moving, thus eliminating the risk of the ground cord breaking at the terminal portion. be able to.
