Generally, this type of lamp socket device considering waterproofness and vibration resistance has elasticity such as rubber as described in Japanese Utility Model Publication No. 2649469 published by the Japan Patent Office. A conductive terminal and a wedge-based lamp are housed in a hollow socket body with a bottom formed of a material. Inserts the lamp socket device, which has a flange with a diameter larger than the outer diameter of the cylindrical portion of the socket body, into the cylinder formed in the mounting housing containing the auto-by-meter, for example, from the outer bottom surface of the mounting housing. A bulging portion (locking portion) is provided in the middle of the cylindrical portion of the socket body and locked to the upper edge of the cylinder, and is engaged with the cylinder of the mounting housing. However, in the conventional example, when the lamp socket device is engaged in the cylinder of the mounting housing, a bulging portion (an engaging portion) which is provided around the cylindrical portion of the socket main body and engages with the upper end edge of the cylinder is provided. It had to be inserted while being crushed all around the inner wall, and the workability was extremely poor. In particular, the portion of the cylindrical portion corresponding to the base of the conductive terminal is thinner than the other portions in order to secure a space for accommodating the conductive terminal, and the base of the conductive terminal is located inside. Therefore, the amount of collapse was small and the resistance was large.

As a method of solving such a situation, oil or the like was applied around the socket body or the inner wall of the cylinder, but there were problems in terms of workability and control of the applied amount.

The present invention has been made in view of the above points, and has been made while maintaining waterproofness and vibration resistance. It is an object of the present invention to provide a lamp socket device that can be easily mounted on a housing with a lamp. Disclosure of the invention

The electric cord connected to the conductive terminal is connected to the bottom side of the socket main body. The conductive terminal is pulled out from the pair of holes, and a clamping piece is bent at substantially right angles from both sides of the base of the conductive terminal, and an edge-base lamp is inserted and clamped from the opening side of the socket body. In a lamp socket device in which a sealing portion of a lamp is sandwiched by a piece and the locking portion is engaged with a socket receiver provided in a mounting housing, the locking portion corresponds to at least a base of the conductive terminal. Except for places It is provided.

Further, a hollow portion is provided in the socket body corresponding to at least the locking portion on the side orthogonal to the sealing portion of the lamp. BRIEF DESCRIPTION OF THE FIGURES

FIG. 1 is an exploded perspective view of a lamp socket device showing an embodiment of the present invention, FIG. 2 is a cross-sectional view when the lamp socket device is inserted, and FIG. FIG. 4 is a front view of the lamp socket device excluding the lamp, and FIG. 5 is a rear view of the lamp socket device. BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described with reference to the accompanying drawings.ゥ The edge-based lamp 1 has a spherical portion 2 and a sealing portion 3. The hollow bottomed socket body 4 is made of rubber, which is an elastic material, and is provided with a hollow cylindrical portion 5 and a flange portion 6 having a diameter larger than the cylindrical portion 5 around the bottom of the cylindrical portion 5. It is. Lamp 1 spherical inside the upper part of the socket body 4 A circular first space portion 7 in which a part of the portion 2 is stored is formed, and a substantially rectangular second space portion 8 is formed in the middle of the inside.

A pair of conductive terminals 9 are accommodated in the second space 8 so as to face each other. The conductive terminals 9 are formed by bending holding pieces 11 from both sides of the base 10 at substantially right angles. An inward curved portion 12 is formed on the upper side of 11, and the sealing portion 3 of the lamp 1 is held between the curved portions 12. An electric cord 13 is crimped and fixed to the lower side of the base 10, and the electric cord 13 is drawn out of the socket body 4 through a pair of holes 14 formed on the bottom side of the socket body 4. I have.

Then, when this socket body 4 is inserted into the cylindrical socket receiver 16 provided in the mounting housing 15 through the lower insertion hole as shown in FIG. 2, the upper edge of the socket receiver 16 is used. In the case of the example, the locking portion 18 that is engaged with the step 17 is a portion corresponding to the base 10 of the conductive terminal 9, that is, excluding the thin portion of the cylindrical portion 5 where the base 10 of the conductive terminal 9 is located. It is provided around the cylindrical portion 5 of the socket body 4. The locking portion 18 is located below the curved portion 12 formed on the holding piece 11. The cylindrical portion 5 between the flange portion 6 and the locking portion 18 is provided with a projection 19 that comes into contact with the inner wall of the socket receiver 16.

FIG. 3 shows a cross section of the lamp 1 in a direction orthogonal to the sealing portion 3 (a side cross section in FIG. 2). The socket is formed from the lower side of the curved portion 12 formed on the holding piece 11 of the conductive terminal 9. A hollow portion 20 is provided in a thick portion extending to the bottom of the main body 4.

The method of inserting the lamp socket device configured as described above into the socket receiver 16 is as follows. The lamp socket device is inserted into the cylindrical socket receiver 16 formed integrally with the mounting housing 15 from the lamp 1 side. Although the locking part 18 of the main body 4 is inserted into the inner wall of the socket receiver 16 while being crushed, the socket body 4 corresponding to the base 10 of the conductive terminal 9 that is most susceptible to resistance when inserting the socket body 4 Since the locking portion 18 is not provided at a portion where the thickness is small, there is no crushing at that portion, and the workability of inserting the socket body 4 into the socket receiver 16 is good. Also, a hollow portion 2 is formed on a side perpendicular to the sealing portion 3 of the lamp 1 and in a thick portion from the lower side of the curved portion 12 formed on the holding piece 11 of the conductive terminal 9 to the bottom of the socket body 4. When the socket body 4 is inserted into the socket receiver 16, the locking portions 18 where the hollow portions 20 are provided are socketed. Since it is inserted into the center of the main body 4 while being bent, there is no crush at that part, the workability of inserting the socket main body 4 into the socket receiver 16 is good, and there is no need to apply oil or the like. The lamp socket device inserted into the socket receiver 16 in this manner is mounted on the mounting housing 15 with the lower end of the locking portion 18 locked by the stepped portion 17 of the socket receiver 16. The flange portion 6 is in close contact with the bottom surface of the mounting housing 15 to close the insertion hole of the socket receiver 16 to prevent water or the like from entering. Further, by providing a projection 19 between the flange portion 6 and the locking portion 18, the projection 19 is in close contact with the inner wall of the socket receiver 16, so that water or the like is further prevented from entering. In addition, since the socket body 4 is formed of rubber, which is a flexible material, external vibrations and impacts applied to the mounting housing 15 are attenuated and transmitted to the lamp 1, so that the lamp 1 is not broken and does not break. Are better.

Although the socket receiver 16 is formed integrally with the mounting housing 15 in the present embodiment, a separate member may be mounted and fixed to the mounting housing 15. Further, the socket receiver 16 may not have a portion above the stepped portion 17. Industrial applicability

As described above, the present invention is suitable for a lamp socket device exposed to an external atmosphere and used in a vibrating atmosphere.
