Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp in which a fitting portion of a socket is fitted in a fitting hole provided in a rear portion of a housing and the socket is mounted in the housing.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as a vehicle lamp, one shown in FIGS. 4 to 6 is known. 4 to 6, reference numeral 1 denotes a housing having a lens (not shown) attached to a front opening, and a rear portion 2 of the housing 1 has a fitting hole 3 for a socket. The fitting hole 3 is formed with an annular groove 4 and recesses 5 ... That extend from the end surface 2a of the rear portion 2 to the annular groove 4.

On the other hand, the socket 7 to which the valve 6 is attached is formed with a fitting portion 7a which fits into the fitting hole 3, and the fitting portion 7a is provided with projections 8 ... ing. 9 is an O-ring.

To mount the socket 7 in the housing 1, the projections 8 of the socket 7 are inserted into the recesses 5 of the fitting hole 3 and the fitting portion 7 a is fitted into the fitting hole 3. Then, when the projections 8 ... Enter the annular groove 4, the socket 7 is rotated by a predetermined angle so that the projections 8 ... This engagement is intended to prevent the socket 7 from coming off.

[0005]

[Problems to be solved by the device]

 However, in such a vehicular lamp, in order to prevent the socket 7 from coming off, it is necessary to rotate the socket 7 to engage the projections 8 with the annular groove 4. There was a problem that it was difficult to automate the line for installing the. Further, since the socket 7 is rotated, the workability is poor, and the reaction force of the O-ring prevents the socket 7 from being set to a position rotated by a predetermined angle, which makes it difficult to find the position where the valve 6 is normally mounted. There were many problems.

The present invention has been made in view of the above problems, and an object thereof is to mount a socket by simply inserting the socket into a fitting hole of a housing without rotating the socket. The purpose is to provide lighting.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention fits a fitting part of a socket for mounting a valve into a fitting hole provided at a rear part of a housing having a lens mounted on a front opening, and mounts the socket on the housing. In a vehicular lamp, a guide groove is provided in the fitting hole along the fitting direction and a recess is provided in the guide groove, and a projection for entering the guide groove is provided in the fitting portion of the socket, and the projection is provided in front of the projection. The protrusion is provided with an engaging portion that engages with the recess when the socket is inserted into the guide groove and attached to the housing.

[0008]

[Action]

 According to this invention, with the above structure, when the protrusion provided on the fitting portion of the socket is inserted into the guide groove provided in the fitting hole of the housing and the socket is attached to the housing, the locking portion provided on the protrusion is It engages with the recess provided in the guide groove.

[0009]

【Example】

 An embodiment of a vehicular lamp according to the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, reference numeral 20 denotes a housing having a lens (not shown) attached to a front opening, and a fitting hole 22 is provided in a rear portion 21 of the housing.

In this fitting hole 22, guide grooves 23 are provided at four locations along the direction in which a socket 30 described later is fitted, and a recess 24 is formed in each guide groove 23. The recess 24 has a contact surface 24a that is orthogonal to the fitting direction.

On the other hand, the fitting portion 31 of the resin socket 30 is provided with a protrusion 32 that enters the guide groove 23, and the protrusion 32 is provided with an engaging portion 33 that engages with the recess 24. Has been. The engaging portion 33 has an inclined surface 33a and a locking surface 33b for locking the contact surface 24b. Further, the protrusion 32 has a notch 34 so that it can be elastically deformed. Reference numeral 35 is a valve attached to the socket 30, and 36 is an O-ring.

To mount the socket 30 on the housing 20, the protrusion 32 of the socket 30 is inserted into the guide groove 23 of the housing 20, and the fitting portion 31 of the socket 30 is inserted into the fitting hole 22 of the housing 20 from the direction of the arrow. Insert it. With this insertion, the protrusion 32 is guided by the inclined surface 32a into the guide groove 23 and elastically deforms, whereby the engaging portion 33 enters the guide groove 23, and the fitting portion 31 is fitted into the fitting hole 22. It will be done.

When the fitting portion 31 is fitted into the fitting hole 22 to the predetermined position shown in FIG. 3, the restoring force of the protrusion 32 causes the engaging portion 33 of the protrusion 32 to engage with the recess 24 of the guide groove 23. It By this engagement, the engagement surface 33b of the engagement portion 33 is engaged with the contact surface 24a of the recess 24, and the socket 30 is attached to the housing 20. The locking prevents the socket 30 from coming off.

As described above, the socket 30 can be attached to the housing 20 only by inserting the fitting portion 31 of the socket 30 into the fitting hole 22 of the housing 20, so that the line for attaching the socket 30 can be easily automated. Moreover, since it is not necessary to rotate the socket 30, the mounting work thereof is simple. Further, since the socket 30 is not rotated, the reaction force of the O-ring 36 is not generated, and as a result, the valve 36 can be easily mounted in the proper position.

[0016]

[Effects] According to the present invention, the socket can be attached to the housing simply by inserting the fitting portion of the socket into the fitting hole of the housing. Therefore, it is easy to automate the line for attaching the socket and rotate the socket. Since it is not necessary to do so, the mounting work is simple. Further, since the socket is not rotated, the reaction force of the O-ring interposed between the socket and the housing is not generated, and as a result, it becomes easy to position the valve properly.
