[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle interior light, and more particularly to a vehicle interior light in which a power supply unit and a power-supplied supply unit are electrically connected using a vehicle body panel.

[0002]

[Prior art]

 Conventionally, as such a vehicle interior light, there is one as shown in FIG. The vehicle interior light 1 includes a resin housing 3 formed in a predetermined shape along a vehicle body panel 2 electrically connected to a power supply unit (not shown), and a lens 4 attached to the housing 3. , And a connecting portion 7 for holding a bulb 6 whose lighting state is switched by operating the switch portion 5.

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

As shown in FIG. 3B, the terminal 9 has a recessed portion 9 a that fits into a cylindrical holding projection 3 a that is projected on the back surface of the housing 3, and a position that is similarly projected on the back surface of the housing 3. The positioning projection 9b is provided with a positioning hole 9b. Further, an insertion hole 9c into which the screw 10 for fixing the housing 3 to the vehicle body panel 2 is inserted is formed coaxially with the screw hole 3c of the housing 3 in the recess 9a.

Therefore, the terminal 9 is fitted with the recess 9a in the holding projection 3a in a positioning state in which the positioning hole 9b is engaged with the positioning projection 3b, and then the screw 10 is inserted into the screw hole 3c and the insertion hole 9c. By being inserted and tightened, it is electrically connected to the vehicle body panel 2 and power is supplied to the valve 6.

[0006]

[Problems to be solved by the device]

 By the way, in the vehicle interior light 1 configured as described above, the vehicle body panel 2 and the terminal 9 are brought into direct contact with each other to be electrically connected to the power supply unit. If there is a blockage such as dust between the vehicle body panel 2 and the concave portion 9a, the electric connection becomes incomplete, and when the screw 10 is tightened, the concave portion 9a is externally connected. There was a problem that it was not possible to detect the existence of the obstacle because it was not visible.

The present invention has been made in view of the above circumstances. Not only can the electric connection with the vehicle body panel be surely made, but also an obstacle to be checked when the screw member is tightened is externally confirmed. It is an object of the present invention to provide a vehicle interior light that can be used.

[0008]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the object, a conductive vehicle body panel provided with a mounting hole is electrically connected to a power supply portion, and a back surface of a resin housing is in contact with the vehicle body panel and the mounting hole is provided. A step portion is formed by drilling a screw insertion hole coaxial with the step portion, and the side wall of the step portion extends along the back surface of the housing and has the other end of the wiring plate whose one end is connected to the power-supplied part in the step portion. A slit for insertion is formed, and the step portion is integrally fixed to the vehicle body panel with the other end of the wiring plate via a conductive screw member, and the vehicle body plate and the wiring plate are connected via the screw member. The main point is that they are electrically connected.

[0009]

[Action]

 In such a configuration, by fixing the step portion to the vehicle body panel integrally with the other end of the wiring plate via the conductive screw member, the vehicle body plate and the wiring plate are electrically connected via the screw member. It

[0010]

【Example】

 Next, an embodiment of the vehicle interior light of the present invention will be described with reference to FIGS.

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 attached to the resin housing 13, and a lens (not shown). And a connection part 17 for holding a bulb 16 as a power source supply part whose lighting state is switched by operating a switch part 15 electrically connected to one supply terminal (for example, plus) of the power supply part. There is.

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

The resin housing 13 is formed with a step portion 13b protruding toward the back surface so as to have a cylindrical recess 13a coaxial with the mounting hole 12a. In addition, a semi-arcuate slit 13c is formed on the side wall of the step portion 13b so as to connect the outside of the back surface of the resin housing 13 and the recess 13a. Further, a screw insertion hole 13d is formed at the center of the step portion 13b.

The connecting portion 17 includes a terminal 18 that holds one end of the valve 16 at one end 18a and a terminal 19 as a connecting plate that holds the other end of the valve 16 at one end 19a.

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

A screw insertion hole 19 is formed in the other end 19b of the terminal 19. In addition, the terminal 19 is inserted into the recess 13a of the step portion 13b from the outside through the slit 13c from the other end 19b, and then integrated with the housing 13 through a screw member 23 including a conductive screw 21 and a washer 22. It is fixed to the vehicle body panel 12.

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

After the valve 16 is provided between the terminals 18 and 19, the lens 14 is attached to the housing 13, and the switch unit 15 and one of the supply terminals of the power supply unit are connected to each other to thereby connect the switch unit. The terminal 18 is in the power supply state according to the operation status of 15.

Since the vehicle body panel 12 is electrically connected to the other supply terminal of the power supply unit, the terminal 19 is screwed into the screw member 23 when the terminal member 19 is fixed integrally with the housing 13 by the screw member 23. After that, the power is supplied.

At this time, since the other end 19b of the terminal 19 before mounting the screw member 23 is in a state of being exposed to the outside from the recess 13a, even when a blocking material such as dust adheres to the surface thereof, etc. Since the blocker can be confirmed and removed, by simply tightening the conductive screw member 23, the electrical connection with the vehicle body panel 12 can be surely made through the screw member 23.
