BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp, such as a map lamp, which is attached to a vehicle body by removing the cover and operating from the opening of the lamp body, and is particularly excellent in workability and safety. Vehicle lighting.

[0002]

2. Description of the Related Art In a conventional vehicle lamp of this type, for example, a map lamp, generally, a lamp body having an opening, a light source bulb provided in the lamp body, and the light source bulb and a power source are connected to each other. Wiring and a cover that is detachably attached to the edge of the opening and covers the opening. And
When the lamp body is attached to the vehicle body, the cover is detached from the lamp body to open an opening, and the lamp body is operated to attach the lamp body to the vehicle body. Thus, by turning on the light source bulb, the light from the light source bulb is applied to a predetermined position.

[0003]

However, in the above-described conventional vehicle lamp, the cover is simply detachably attached to the edge of the opening of the lamp body and the opening is covered with the cover. When the main body is attached to the vehicle body, the cover removed from the lamp main body and the lamp main body are separate. For this reason, if the cover is accidentally dropped when it is removed, the cover may hit an operator and may be injured, or the cover may fall to the floor and be damaged. Also, while installing the lamp body to the vehicle body,
Since it is necessary to store and manage the removed cover, there is a problem that the work of mounting the lamp body becomes complicated.

An object of the present invention is to provide a vehicular lamp having good safety and workability.

[0005]

The present invention is characterized in that wiring for connecting a light source bulb and a power source is attached to a cover.

[0006]

The present invention has the above-described structure, and even if the cover is accidentally dropped when it is removed, the cover is connected to the lamp body through the wiring, so that the cover may hit an operator and cause injury. There is no risk that the cover will fall on the floor and be damaged. Further, since the removed cover and the lamp body are connected to each other via wiring, it is not necessary to store and manage the cover while the lamp body is attached to the vehicle body, and the workability is improved accordingly.

In the drawing, reference numeral 4 denotes a hollow, substantially cubical middle housing having an open bottom. A mounting boss portion 40 is provided on the upper portion of the middle housing 4, and a base 41 is fixed to the upper portion of the middle housing 4 by rivets.
A positive terminal / holder 42 and a negative terminal / holder 43 are fixed to the base 41 by rivets. The mounting boss portion 40 of the middle housing 4 and the mounting seat 22 of the upper housing 2 are mounted by a screw 231 with a bracket 6 described later interposed therebetween, and the lower surface opening of the middle housing 4 is attached to the lens of the lower housing 3. The two middle housings 4 are assembled to the upper housing 2 and the lower housing 3 by fitting them into the edge of the opening 30 for assembling.

In the figure, 5 is a lens. An engaging claw 50 is provided at the end of the lens 5. The engaging claw 50 of the lens 5 is engaged with the engaging groove 35 of the lower housing 3,
The two lenses 5 are detachably incorporated in the two openings 30 of the lower housing 3, respectively. The lens 5 and the middle housing 4 define two lamp chambers 51. In the figure, 6 is between the mounting seat 21 of the upper housing 2 and the mounting boss portion 32 of the lower housing 3, and between the mounting boss portion 40 of the middle housing 4 and the mounting seat 22 of the upper housing 2. It is a bracket interposing each. A bolt insertion hole (not shown) is attached to the bracket 6.
It is provided so as to correspond to the bolt insertion hole of the vehicle body 1 and the screw hole of the nut 10. Reference numerals 60 denote switches attached to the two openings of the lower housing 3, respectively. The upper housing 2, the lower housing 3, the middle housing 4, the lens 5, the bracket 6 and the like constitute a lamp body A of the map lamp.

In the drawing, 7 is a light source bulb. The two light source bulbs 7 are held by the plus terminal / holder 42 and the minus terminal / holder 43 respectively, and the two light source bulbs 7 are held by the two lamp chambers 5.
Each of them is located at a predetermined position within 1. In the figure,
Reference numeral 70 denotes a reflector arranged in the lamp chamber 51. The reflector 70 reflects the light from the light source bulb 7 and irradiates the reflected light to a predetermined position via the lens 5.

In FIG. 5, reference numeral 71 is a power source (battery). The power source 71 is connected to the two light source bulbs 7. That is, the power source 71 and the power source side connector 72 disposed in the lamp body A are connected by the first wiring 73, and the bulb side connector 74 and the above two positive terminals are paired with the power source side connector 72.

In the figure, reference numeral 8 denotes a cover having a size and shape capable of covering the operation opening 31 of the lower housing 3. An engagement claw 80 is provided on the inner surface of the cover 8, and an engagement step 81 is provided at the end of the cover 8. The valve side connector 74 is attached to the inner surface of the cover 8. The engaging claw 80 and the engaging stepped portion 81 of the cover 8 are engaged with the engaging convex portion 33 and the engaging portion 34 of the lower housing 3, respectively, and the cover 8 is attached to the lower housing 3 (the lamp body A). ), And covers the opening 31 for operation of the lower housing 3 (lamp body A).

The vehicular lamp of the present invention according to this embodiment has the above-described structure, and a method of mounting the lamp body A of the present invention on the vehicle body 1 will be described below. First, cover 8
Is removed from the lower housing 3, the connectors 72 and 74 are removed, and the opening 31 for operation is opened. At this time, even if the cover 8 is accidentally dropped when the cover 8 is removed, the cover 8 is connected to the lamp body A through the bulb-side connector 74 and the second wiring 75, so that the cover 8 is not exposed to the operator. There is no risk of injury by hitting it or its cover falling to the floor and being damaged. next,
The lamp body A is set on the vehicle body 1, and the bolt insertion hole on the vehicle body 1 side and the screw hole of the nut 10 are aligned with the bolt insertion hole on the lamp body A side. Then, the bolt 11 is inserted into the lamp body A through the opening 31 for operation, and the bolt 11 is inserted into the bolt insertion hole on the lamp body A side and the vehicle body 1.
The lamp body A is attached to the vehicle body 1 by being screwed into the screw hole of the nut 10 through the bolt insertion hole on the side. Then, the connectors 72 and 74 are incorporated, and the cover 8 is attached to the lamp body A to cover the operation opening 31. As described above, the removed cover 8 and the lamp body A are connected to each other through the bulb-side connector 74 and the second wiring 75. Therefore, it is necessary to manage the cover 8 while the lamp body A is attached to the vehicle body 1. The workability is improved accordingly.

Although the map lamp has been described in the above embodiments, the vehicle lamp of the present invention can be used for lamps other than the map lamp.

[0015]

As is apparent from the above, since the vehicular lamp of the present invention has the wiring for connecting the light source bulb and the power source attached to the cover, it may be accidentally dropped when the cover is removed. However, since the cover is connected to the lamp body via the wiring, there is no risk of the cover hitting an operator and being injured, or the cover falling to the floor and being damaged. Further, since the removed cover and the lamp body are connected to each other via wiring, it is not necessary to manage the cover while the lamp body is attached to the vehicle body, and the workability is improved accordingly.
