And one end (not shown) of the second terminal plate 7 is engaged with one end 7a of the second terminal plate 7, and is held by the engagement with the plates 6 and 7.

[0004] The second terminal plate 7 electrically connects one electrode of the battery and the other metal opening 3 a of the bulb 3.

The operation switch 2 is also electrically connected to the third and fourth terminal plates 8 and 9 so as to switch between a mode in which the valve 3 is always turned off, a mode in which the valve 3 is turned on, and a mode in which the valve 3 is automatically turned on and off in conjunction with opening and closing of the door. It can be connected to.

The third and fourth terminal plates 8 and 9
Is electrically connected to the other electrode of the battery,
Depending on the mode position of the operation switch 2, the first terminal plate 6 and one of the third and fourth terminal plates 8 and 9 are electrically connected to each other. Are electrically connected.

By the way, as shown in FIG. 3B, the first and second terminal plates 6 and 7 are provided in a direction from the operation switch 2 to the bulb 3 in order to realize a compact lamp body. It is formed in a predetermined shape by a combination of a direction intersecting with the direction. Therefore, each part is arranged in the housing 1 in a state of being very close to each other, and is locked by a claw member 10 formed integrally with the housing 1 as shown in FIG.

The claw member 10 is connected to the first terminal plate 6.
And a connecting portion 7 extending from the valve holding portion 7a of the second terminal plate 7 toward the operation switch 2 and intersecting the mounting surface 1b.
b and a contact portion 10b that comes into contact therewith.

[0009]

By the way, in the vehicle interior light 5 configured as described above, the claw member 10 is
The contact surface 10a is simply the upper surface 6 of the first terminal plate 6.
a, the first terminal plate 6 may be displaced along the mounting surface 1b depending on, for example, the operation of the operation switch 2 or the impact when the occupant touches the lamp body. If the direction of displacement is the direction shown by the arrow A in FIG. 3B, that is, if the direction of displacement approaches the valve holding portion 7a of the second terminal plate 7, there is a problem that an electric short circuit occurs. Had occurred.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a vehicle interior light capable of preventing a possibility that adjacent terminal plates come into contact with each other to cause an electric short circuit. Things.

[0011]

According to the present invention, an operation switch rotatably held by a housing is provided to achieve the object .
A valve located approximately at the center of the housing from the switch
And extending in a direction crossing this direction.
A plurality of terminal plates are provided on the housing.
And two of the plurality of terminal plates
The valve is held, and the multiple
Based on the number of terminal plate connections selected
In the vehicle interior light where
The plate is formed with an engagement recess that opens at the edge of the plate.
The terminal plates are separated from the housing
An abutting portion to be engaged and an engaging protrusion which resiliently engages with the engaging recess.
It is essential that the elastic claw member formed with is formed integrally with the projection .

[0012]

In such a structure, the engagement opening at the edge is provided.
A mating recess is formed in the terminal plate and
An engaging projection is formed on the protruding elastic claw member, and
When the separated state of each terminal plate is maintained,
The engagement recess is elastically engaged with the engagement projection to
The movement of the minal plates approaching each other was restricted
Therefore, even if an occupant touches the lamp body by operating the operation switch or receives an impact when the occupant touches the lamp body, the separated state is maintained, and the first terminal plate and the second terminal plate come into contact with each other to cause an electric short circuit. Nothing.

[0013]
