Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a valve mounting opening formed in a rear wall of a housing which opens to the front, and a valve socket holding the valve is engaged with the valve mounting opening to hold the valve in the housing. Vehicle lighting fixtures.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5 (A), a valve mounting opening 1c is formed in a rear wall 1b of a housing 1 having an opening 1a on the front surface, and the opening 1a covers the outer lens 2.
And the inner lens 3 are closed to form the lamp chamber 4, and the bulb socket 6 holding the bulb 5 is engaged with the bulb mounting opening 1c so that the bulb 5 located in the lamp chamber 4 is retained in the housing 1. A vehicular lamp 7 is known.

As shown in FIG. 6, the valve 5 has a flat base portion 5a at one end thereof. By inserting the base portion 5a into the valve holding portion 6a of the valve socket 6, the valve holding portion 6a is inserted into the valve holding portion 6a. It is sandwiched by provided terminals (not shown) and electrically connected.

The valve socket 6 is provided with an annular flange portion 6b and a pair of engaging claws 6c, 6c projecting from the flange portion 6b, and the valve socket 6 is inserted into the valve mounting opening 1c while holding the valve 5. Installing.

On the other hand, when replacing the valve 5, the engaging claw 6
The valve socket 6 can be detached from the housing 1 by releasing the engagement state of c and 6c and pulling out the valve socket 6 integrally with the valve 5.

[0006]

By the way, in the vehicular lamp 7 configured as described above, when the bulb 5 is replaced, the bulb socket 6 is detached from the housing 1 integrally with the bulb 5. When pulled out, as shown in FIG. 5 (B), the bulging base end portion 5b of the valve 5 comes into contact with the opening edge portion of the valve mounting opening 1c, and in particular, the center of the bulging base end portion 5b is displaced. If the pulling out is continued while being in contact with the opening edge of the bulb mounting opening 1c, the bulb 5 may drop from the bulb socket 6 and the bulb 5 may remain in the lamp chamber 4.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicular lamp capable of preventing the bulb from falling off when the bulb socket is pulled out.

[0008]

In order to achieve the object, the invention according to claim 1 has a valve mounting opening formed in a rear wall of a housing which is open to the front and holds the valve in the valve mounting opening. In the vehicular lamp holding the bulb socket, the gist is that the housing is provided with a rib that is proximate to an opening edge portion of the bulb mounting opening and extends toward the front surface.

[0009]

In the above-mentioned structure according to claim 1,
A rib formed on the rear wall of the housing with a valve mounting opening opening to the front, holding a valve socket holding the valve in the valve mounting opening, proximate the opening edge of the valve mounting opening, and extending toward the front. Is provided in the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a vehicular lamp of the present invention will be described with reference to the drawings.

In FIG. 2A, the vehicle lamp 10 is
A housing 11 having an open portion 11a on the front surface, an outer lens 12 and an inner lens 13 that close the open portion 11a, a lamp chamber 14 formed by closing the open portion 11a with the lenses 12 and 13, and a housing. 11 and a valve body 15 held in a valve mounting opening 11c formed in a rear wall 11b.

The valve body 15 is provided with a valve 5 and a valve socket 6 holding the valve 5. still,
Since the valve 5 and the valve socket 6 are the same as the above-described conventional valve 5 and valve socket 6, the detailed description of the structure is given the same reference numerals and omitted.

When the bulb socket 6 with the bulb 5 held therein is inserted into the lamp chamber 14 side, the engaging claws 6c and 6c are formed.
c contacts the opening edge of the bulb mounting opening 11c and bends toward the optical axis, and when the tips of the engaging claws 6c and 6c are located in the lamp chamber 14, the bending is released and the engaging claws 6c and 6c. And collar part 6
The opening edge portion of the valve mounting opening 11c is sandwiched with b, and the housing 11 is mounted by this sandwiching.

The number, positions, shapes, etc. of the engaging claws 6c, 6c are not particularly limited, and if the valve 5 is inserted and held in the valve socket 6, for example, the valve socket is used. A type in which 6 is rotated and attached to the housing 11 (see FIG. 1B) may be used.

On the other hand, in the housing 11, as shown in FIG.
As shown in (B), an annular rib 11d is provided so as to be close to the opening edge portion of the valve mounting opening 11c and surround the opening edge portion.

When the valve main body 15 is mounted on the housing 11, the rib 11d extends substantially parallel to the optical axis of the valve main body 15 toward the open portion 11a side, and has an extended length and an annular diameter (internal). The peripheral surface is the size of the valve body 15, the length in the direction along the optical axis, or the valve mounting opening 11c.
The diameter is set to 26 mm (for example, diameter 26 mm, extension length 10 mm).

By the way, the rib 11d has, in addition to the above-described annular shape, for example, as shown in FIGS. 3 (A) and 3 (B), when the valve body 15 is pulled out, in the pulled out state, the surface of the base portion 5a of the valve 5 is removed. May be provided in a circular arc shape corresponding to a portion facing to, that is, a portion where the bulging base end portion of the valve 5 comes into contact with the opening edge portion of the valve mounting opening 11c.

Incidentally, FIG. 3A shows an insertion type of the valve body 15, and FIG. 3B shows an insertion rotation type of the valve body 15. Further, reference numerals 11e and 11e in FIG. 3B are recesses for inserting the engaging claws 6c and 6c which are opened to the valve mounting opening 11c.

Further, as shown in FIG. 4, by forming a reflecting surface 11f along the parabolic surface at the tip of the rib 11d, the light distribution is improved and the appearance of the rib 11d is improved (from the outside 1
It is difficult to understand the existence of 1d).

In the above structure, when the valve body 15 is pulled out from the housing 11 by replacing the valve 5 or the like, even if the pulling out direction is slanted as shown in FIG. The leading end of the valve abuts on the rib 11d, and its withdrawal angle and the deviation of the valve mounting opening 11c to the outside of the opening edge are restricted, so that the valve 5 can be withdrawn without falling off.

A rear wall 11b is provided between the valve mounting opening 11c and the rib 11d because the engaging claws 6c, 6c are engaged with each other.
Part (opening edge) of the valve 5
There is a case where the bulging base end portion 5b of the valve abuts on a part thereof, but since the contact at this time is an R-shaped corner portion between the outer wall of the valve 5 and the bulging base end portion 5b, the catching is extremely small. The valve body 15 is slightly guided by the corner portion, and the valve body 15 does not deviate from the center of the valve mounting opening 11c, so that the valve 5 does not drop from the valve socket 6 due to withdrawal.

[0022]

As described above, in the vehicular lamp of the present invention, the housing is provided with the rib that is close to the opening edge portion of the bulb mounting opening and extends toward the front surface. It is possible to prevent the valve from falling off when pulling out the valve socket.
