[Detailed Description of the Invention] The present invention relates to an improved structure of a push-fit type lamp socket device for illuminating a display section of a motorcycle instrument, which is exposed to an external atmosphere and used in a vibrating atmosphere, for example. be.

Conventionally, there has been a socket of this type in which a cylindrical body made of an elastic body is press-fitted into a metal outer cylinder, as disclosed in Japanese Utility Model Publication No. 51-39408.
However, since the electrical cord is still led out from the bottom of the socket, it may be difficult to guide the electrical cord in the direction of routing, and the electrical cord may get in the way. This can lead to inconveniences such as the need to push and install the instrument into the instrument case.

In view of the above-mentioned circumstances, this invention prevents electrical failures in a vibrating atmosphere, suppresses water temperature and dust intrusion in the external atmosphere, and facilitates the guidance of a pair of electrical cords led out from the bottom of the socket. The purpose of this device is to provide a lamp socket device with a lamp socket device, and its characteristic structure is that a hollow socket body with a bottom is formed of a flexible material such as rubber, and a lamp body is mounted on the top of the socket body. A first space part is formed to surround and support the spherical part of the socket body, and a second space part is formed in the lower part of the socket body to support a pair of conductive terminals, and a second space part is formed in the second space part to support a pair of conductive terminals. A pair of conductive terminals connected to an electrical cord are housed and arranged, and a wedge-based lamp body is inserted through the upper opening of the socket body to support the lamp body on the pair of conductive terminals, and the lamp body is supported by the pair of conductive terminals. A pair of holes are formed in the bottom wall for guiding the electrical cord outward, and a pair of grooves for supporting the electrical cord midway through the socket body are formed in the outer bottom surface of the socket body. The lamp socket device is shaped so that the pair of electric cords can be guided along the outer bottom surface of the socket body.

An embodiment of the present invention will be described below with reference to the accompanying drawings FIGS. 1 to 6.

A hollow socket body 1 with a bottom is made of a flexible material such as rubber and has a certain shape, and a first space portion 2 is formed inside the upper part of the body 1.
However, a second space part 3 communicating with the first space part 2 is formed on the inside of the lower part, and the first and second space parts 2 and 3 face each other toward the center of the inside of the socket body 1. It is divided by a step 4.

A pair of holes 5 communicating with the second space 3 are formed on the outer bottom surface of the socket body 1, and two grooves 6 are formed in parallel with the outer bottom surface and communicating with the holes 5. is taking shape.

A pair of substantially U-shaped conductive terminals 7 are inserted into the second space 3 of the socket body 1 at a distance above the hole 5, and at this time, the terminals 7 are inserted into the space. The terminal 7 is housed and held in the portion 3 and is disposed so as to bias the opening side thereof in a closing direction, and the open free end of the terminal 7 is bent outward to come into contact with the stepped portion 4.

Attached to the lower end of each of the terminals 7 are the free ends of two independent electrical cords 8, which are connected to the socket body 1.
They are each led out from the hole 5 on the outer bottom surface of the hole 5, are bent almost orthogonally from the base, and are stretched along a pair of grooves 6 communicating with the hole 5 to be shaped.

The lamp body 10 has a filament 12 enclosed within a spherical portion 11, and a portion of a thin lead wire 13 connected to the filament 12 is led out to the outside.

The lower end of the lamp body 10 is shaped flat as a sealing part 14, and the thin lead wire 13 led out to the outside is bent upward along this sealing part 14.

By inserting the lamp body 10 into the socket body 1, the flat sealing portion 14 is inserted into the second part of the socket body 1.
clamped between the conductive terminals 7 inserted into the space 3 of the
At the same time, the thin lead wire 13 and the terminal 7 are connected to form an electric line, and a part of the spherical portion 11 of the lamp body 10 is disposed within the first space 2 of the socket body 1.

That is, in the present invention, the flat sealing portion 14 of the lamp body 10 is crimped and clamped between a pair of substantially U-shaped conductive terminals 7 inserted into the lower second space portion 3 of the socket body 1, and the sealing portion 1
4 is connected to the terminal 7, and a part of the spherical portion 11 of the lamp body 10 is supported in the upper first space 2 of the socket body 1, thereby attaching the lamp body 10 to the socket body 1. It has the advantage that it can be stored stably, and that mechanical separation of the lamp body 10 from the socket body 1 due to applied vibrations and electrical connection failures caused by this can be well prevented.

Also, by bending the base of the cord 8 connected to the terminal 7 and extending outward from the outer bottom hole 5 of the socket body 1, and storing the middle of the cord 8 in the recessed groove 6 along the outer bottom surface, the abdomen of the thumb can be protected. Along the outer bottom surface of the socket body 1, the socket 1 and the main body 1 can be pushed and fixed together with the lamp body 10 into a hole in the outer bottom surface of an instrument case (not shown), so that the base of the cord 8 is inserted into the groove 6. The socket main body 1 does not rise significantly from its outer bottom surface in the longitudinal direction, and this has the advantage that handling during the above-mentioned work is facilitated, the wiring of the cord 8 can be routed neatly, and interference with other parts can be prevented. be.

In this case, depending on the situation, the electric cord 8 may be used as it is led out from the hole 5 without being placed along the groove 6.

In addition, the terminal 7 connected to the cord 8 is folded outward at its open free end to abut against the stepped portion 4 that partitions the first space portion 2 and the second space portion 3. code 8
Even if you pull the cord 8, the terminal 7 will not come out from the bottom hole 5 of the socket body 1.
By simply pulling the cord 8, the socket body 1 can be pulled out from the fixing member. For example, the lamp body 10 can be pulled out together with the cord 8.
This has the advantage that replacement work due to failure can be easily performed.

In addition, FIG. 7 shows another embodiment of the present invention,
In this case, the concave groove 6 has a circular groove 15 at its outer bottom that has almost the same diameter as the cord 8, and after the cord 8 is once fitted into the concave groove 6 having a smaller diameter, it is supported in the circular groove 15. By doing so, the cord 8 is pulled out and guided from the bottom surface of the socket body 1 along the concave groove 6.

As described above, the present invention has a bottomed hollow socket body 1 made of a flexible material such as rubber, and a first space surrounding and supporting the spherical portion 11 of the lamp body 10 in the upper part of the socket body 1. In addition to forming the portion 2, a second space portion 3 for supporting a pair of conductive terminals 7 is formed in the lower part of the socket body 1, and a pair of conductive terminals 7 connected to the electrical cord 8 are formed in the second space portion 3. The conductive terminal 7 is housed and arranged, and the socket body 1
A wedge base type lamp body 10 is inserted through the upper opening, and the lamp body 10 is supported by the pair of conductive terminals 7, and the electric cord 8 is led out to the bottom wall of the socket body 1. A pair of holes 5 are formed, and a pair of grooves 6 for supporting the electric cord 8 are formed on the outer bottom surface of the socket main body 1, extending through the holes 5 and along the outer bottom surface. A pair of electric cords 8 led out from the hole 5 to the outside of the lamp body 10 are bent to form the concave groove 6.
By inserting the above pair of electric cords 8 from the outside into the
Since it is possible to guide the socket body 1 along the outer bottom surface of the socket body 1, it is possible to prevent electrical failure in a vibrating atmosphere, and also to suppress the intrusion of water temperature and dust in the external atmosphere. Since the pair of electric cords 8 derived from the lamp can be easily guided and the push-fitting operation can be easily performed, the lamp socket device can be constructed functionally and economically, which is a practical advantage. has.

Furthermore, by making the diameter of the groove 6 slightly smaller than the diameter of the cord 8, it is possible to store and hold the cord 8 in the groove 6 more effectively.

In this case, when the cord 8 is routed, it is also possible to directly pull out the cord 8 from the hole 5 without having it run along the groove 6.
