(Function) In the present invention, the lamp socket is attached to the socket mounting portion of the appliance body, and the contacts of the lamp socket come into contact with the contacts of the end plate of the appliance body, thereby electrically connecting the lamp socket and the appliance body.

Furthermore, electric wires from the lighting device are connected by being inserted into self-chaining terminals of a terminal block provided on the end plate, and the lighting device is wire-connected to the contacts provided on the end plate.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an elongated frame-shaped instrument body made of a metal plate, and socket mounting portions 2 are formed at both ends of the instrument body 1. As shown in FIG. This socket attachment part 2 is a face plate 1 which becomes a reflective surface of the instrument main body 1! An angular fitting hole 3 is cut out at the end of the fitting hole 3, and engagement pieces 4 are protruded from the outer ends of both side edges of the fitting hole 3.

Furthermore, end plates 5 made of synthetic resin are attached to openings at both ends of the instrument body 1. A pair of contacts 6 are laterally arranged side by side on the inner side of the end plate 5, and a terminal block 7 is integrally protruded from the bottom of the pair of contacts 6.
A self-chaining terminal 8 connected to the pair of contacts 6 is provided at the terminal 8 .

A fitting step 9 is formed on the outer periphery of the end plate 5, and is fitted and fixed to the end opening of the instrument body 1 by the fitting step 9.

11 is a lamp socket, and this lamp socket 11 is
A lamp connecting portion 13 is provided on the inner side of the socket body 12 made of synthetic resin, and a fitting portion 14 corresponding to the fitting hole 3 is provided protruding from the lower part of the socket body 12. Engagement grooves 15 corresponding to the engagement pieces 4 are formed on both upper sides of the engagement portion 14, and the engagement grooves 15 corresponding to the engagement pieces 4 are formed on the outer surface side of the engagement portion 14 at positions corresponding to the pair of contacts 6, as shown in FIG. A pair of contacts 16 connected to the lamp connection part 13 are arranged in parallel.

Further, a cover part 17 that covers the fitting hole 3 is integrally provided at the lower part of the socket body 12, and an elastic part 19 is formed in the center of the cover part 17 through slits 18 on both sides. An L-shaped stopper 20 is provided protruding from the lower part of the elastic part 19.

Then, when assembling, please refer to Figures 3, 4 and 5.
As shown in the figure, the end plates 5 are attached to the openings at both ends of the appliance body 1, and the electric wires 21 for wiring from the lighting device arranged inside the appliance body 1 are inserted into the self-locking terminals 8 of the terminal block 7. and connect the wires.

Further, the lamp socket 11 is attached to the socket attachment portions 2 at both ends of the appliance body 1. That is, lamp socket I+
Fit the fitting part 14 into the fitting hole 3, then move the socket body 12 to the outer end side, and fit the fitting groove 1 on both sides of the fitting part 14.
5 is engaged with the engaging piece 4 and further slid, the pair of contacts 16 of the fitting part 14 are brought into contact with the pair of contacts 6 of the end plate 5, and at the same time, the stopper 20 is moved to the inner edge of the fitting hole 3. and attach the lamp socket 11. In this state,
The cover portion 17 closes the fitting hole 3.

In this way, the lamp sockets 11 are attached to opposite ends of the appliance main body 1, and the straight tube fluorescent lamp 22 is attached between the lamp connectors 13.

By doing the above, the lamp socket 11 is attached to the socket attachment part 2 of the appliance body 1, the contacts 16 of the lamp socket 11 come into contact with the contacts 6 of the appliance body 1, and the lamp socket 11 and the appliance body 1 are connected. electrically connected.

Note that when removing the lamp socket 11 from the appliance main body 1, as shown in FIG. 23, lift the elastic part 19, remove the stopper 20, move the lamp socket 11 inward in this state, position the fitting part 14 in the fitting hole 3, and pull it out.

In the above embodiment, the engaging piece 4 is provided in the fitting hole 3 of the appliance main body 1 and engages with the engaging groove 15 of the lamp socket It, but as shown in FIG. Instead of providing the engaging piece 4, the end plate 5 is provided with engaging pieces 4m on both sides connected to the fitting hole 3, and the engaging groove 15 of the lamp socket 11 is engaged with the retaining pieces 41 on both sides. You can do it like this. In addition, when a pair of contacts 6 are provided on the terminal block 7 as in this embodiment,
A pair of contacts 1 are provided on the bottom surface of the fitting part 14 of the lamp socket 11.
6 may be provided.
