The present invention relates to a vehicle interior light,
The present invention relates to a vehicle interior light in which a power supply unit and a power supply unit are electrically connected using a vehicle body panel.

[0002]

2. Description of the Related Art Conventionally, there is a vehicle interior light as shown in FIG. This vehicle interior light 1
A resin housing 3 formed in a predetermined shape along a vehicle body panel 2 electrically connected to a power supply unit (not shown), a lens 4 mounted on the housing 3, and a switch unit 5 are operated. A connection portion 7 for holding a bulb 6 whose lighting state is switched.

The connection section 7 has one terminal 8 electrically connected to the switch section 4 and the other terminal 9 partially located on the back surface of the housing 3.

As shown in FIG. 3 (B), the terminal 9 has a concave portion 9a fitted to a cylindrical holding projection 3a protruding from the rear surface of the housing 3, and a position protruding from the rear surface of the housing 3 similarly. And a positioning hole 9b which engages with the determining protrusion 3b. Further, the housing 3 is provided in the recess 9a with the body panel 2.
An insertion hole 9c into which the screw 10 is inserted when the screw is fixed to the housing 3 is formed coaxially with the screw hole 3c of the housing 3.

Accordingly, after the terminal 9 is fitted with the concave portion 9a in the holding projection 3a in the positioning state in which the positioning hole 9b is engaged with the positioning projection 3b, the screw 10 is inserted into the screw hole 3c and the insertion hole 9c. By inserting and tightening, it is electrically connected to the vehicle body panel 2 and power is supplied to the valve 6.

[0006]

By the way, in the vehicle interior light 1 configured as described above, the vehicle body panel 2 is brought into direct contact with the terminal 9 to be electrically connected to the power supply unit. Therefore, if there is a barrier such as dust between the vehicle body panel 2 and the concave portion 9a, the concave portion 9a separates from the vehicle body panel 2 and the electrical connection becomes incomplete. When tightening the recess 9
There was a problem that it was not possible to discover the presence of the barrier because a was not visible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and enables not only reliable electrical connection to a vehicle body panel but also external confirmation of an obstruction when a screw member is tightened. It is an object of the present invention to provide a vehicular interior light that can be used.

[0008]

According to the present invention, in order to achieve the object, a conductive body panel provided with a mounting hole is electrically connected to a power supply unit, and the body panel is provided on a back surface of a resin housing. And a stepped portion formed with a screw insertion hole coaxial with the mounting hole is formed on the side wall of the stepped portion along the back surface of the housing and having one end connected to a power supply portion. A slit for inserting an end into the step portion is formed, and the step portion is fixed to the vehicle body panel integrally with the other end of the wiring plate via a conductive screw member, and the vehicle body plate and the wiring plate are connected to each other. The point is that they are electrically connected via the screw member.

[0009]

In such a configuration, the step portion is fixed to the vehicle body panel integrally with the other end of the wiring plate via the conductive screw member, so that the vehicle body plate and the wiring plate are electrically connected via the screw member. Connected to.

[0010]

FIG. 1 shows an embodiment of a vehicle interior light according to the present invention.
This will be described with reference to FIG.

In FIG. 1, a vehicle interior light 11 includes a resin housing 13 formed in a predetermined shape along a vehicle body panel 12, a lens 14 detachably mounted on the resin housing 13, and a power supply (not shown). A connection unit 17 for holding a bulb 16 as a power supply unit whose lighting state is switched by operating a switch unit 15 electrically connected to one supply terminal (for example, plus) of the supply unit;

A mounting hole 12a for fixing the vehicle interior light 11 is formed in the vehicle body panel 12. Also, the vehicle body panel is electrically connected to the other supply terminal (for example, minus) of the power supply unit.

The resin housing 13 has a mounting hole 12a.
A step portion 13b protruding toward the rear surface side is formed so as to have a column-shaped concave portion 13a coaxial with. A semi-arc-shaped slit 13 communicating the outside of the back side of the resin housing 13 and the recess 13a is formed on the side wall of the stepped portion 13b.
c is formed. Further, a screw insertion hole 13d is formed at the center of the step portion 13b.

The connecting portion 17 is connected to one end of the valve 16 by one end.
8a and the other end of the bulb 16 at one end 1
And a terminal 19 as a connection plate held at 9a.

The other end 18b of the terminal 18 is fixed to the housing 13 via a screw 20, and is electrically connected to the switch section 15 via a lead (not shown) to supply power to the valve 16.

A screw insertion hole 19 is provided in the other end 19b of the terminal 19.
Are drilled. Further, the terminal 19 is connected to the other end 19b from the outside through the slit 13c through the recess 13a of the step portion 13b.
After being inserted into the housing, the housing 13 is fixed to the vehicle body panel 12 via a screw member 23 including a conductive screw 21 and a washer 22.

In the above configuration, the vehicle interior light 11
After the switch portion 15 and the terminal 18 are fixed to the housing 13, the other end 19 b of the terminal 19 is externally inserted into the recess 13 a through the slit 13 c from this state, and then the terminal 19 is connected to the housing 13 via the screw member 23. 13 and is fixed to the vehicle body panel 12.

The valve 16 is connected between the terminals 18 and 19.
Is provided, the lens 14 is mounted on the housing 13, and the switch unit 15 is connected to one of the supply terminals of the power supply unit.
8 is in a power supply state.

Since the vehicle body panel 12 is electrically connected to the other supply terminal of the power supply unit, the terminal 19 passes through the screw member 23 when the terminal 19 is fixed to the housing 13 by the screw member 23. The power is supplied.

At this time, the other end 19b of the terminal 19 before the screw member 23 is mounted is in a state of being exposed to the outside from the concave portion 13a. Since the obstruction can be confirmed and removed, the electric connection with the vehicle body panel 12 can be reliably performed via the screw member 23 by simply tightening the conductive screw member 23.

[0021]

As described above, in the vehicle interior light according to the present invention, the conductive vehicle body panel provided with the mounting hole is electrically connected to the power supply unit, and is provided on the back surface of the resin housing. A stepped portion formed in contact with the vehicle body panel and formed with a screw insertion hole coaxial with the mounting hole, and a wiring formed on a side wall of the stepped portion along the back surface of the housing and having one end connected to a power supply portion; A slit for inserting the other end of the plate into the step portion is formed, and the step portion is fixed to the vehicle body panel integrally with the other end of the wiring plate via a conductive screw member to thereby connect the vehicle body plate and the wiring. Since the plate and the plate are electrically connected via the screw member, not only the electrical connection with the vehicle body panel can be reliably performed, but also a check for an obstacle when the screw member is tightened is performed from outside. Ukoto can.
