Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for a lighting fixture in which a light emitter is mounted on a printed circuit board.

More specifically, in lighting fixtures used for cassette decks, etc., it is possible to attach the lighting fixture to the mounting plate without requiring a connector or other connecting device to supply power to the light emitting body of the lighting fixture, and without using mounting screws. The present invention proposes a lighting fixture mounting device that can be mounted on a cassette deck, and an embodiment of the present invention used for a cassette deck will be described below with reference to FIGS. 1 to 3.

In Fig. 1, 1 is a synthetic resin fixture whose surface is plated with resin, 2 is a rectangular cylindrical reflecting part with one end open, and 33 is provided on the left and right outer surfaces of the reflecting part 2. The positioning rib 44 is a mounting leg piece that protrudes rearward from the front edge and has a hook portion 55 at its tip, and the reflecting portion 2, the positioning rib 33, and the mounting leg piece 44 are integrally formed. Reference numeral 6 indicates a lighting device having a light emitting body, such as a pilot lamp 8, attached to the printed circuit board 7; 99, a square engagement hole drilled in the printed circuit board 7; and 10, 10, 10, 10, small holes provided in the printed circuit board 7. It is a circular hole. 11 is a mounting plate made of synthetic resin, 12 is a square window hole drilled in the mounting plate 11, 13 and 13 are insertion holes provided on both sides of the window hole, and 14, 14, 14, and 14 are for engagement at the tips. It is an elastic rib provided with protrusions 15, 15, 15, 15.

Next, the procedure for attaching the lighting fixture 6 to the mounting plate 11 will be explained.

First, from the front side of the mounting plate 11, the mounting leg piece 44 of the mounting tool 1 is inserted into the insertion hole 1313 of the mounting plate 11, and the reflecting part 2 is inserted into the window hole 12, respectively. Next, the lighting fixture 6 is attached to the mounting plate 11 from the back side. That is, the lighting fixture 6
The hook portion 55 of the mounting leg piece 44 of the fixture 1 is engaged with the engagement hole 99 of the printed circuit board 7 constituting the
The mounting plate 11 and the printed circuit board 7 are sandwiched between the positioning rib 33 of the mounting tool 1 and the hook portion 55 of the mounting leg piece 44. Furthermore, the elastic rib 1 of the mounting plate 11
4, 14, 14, 14 engagement protrusions 15, 15,
15, 15 into the small circular holes 10, 1 of the printed circuit board 7
0, 10, 10, and the elastic ribs 14, 14
The printed circuit board 7 is pressed toward the hook portion 55 of the mounting leg piece 44 of the fixture 1 (in the direction of arrow A in FIG. 2).

Therefore, even if there are variations in the thickness of the mounting plate 11, the thickness of the printed circuit board 7, the distance between the tip of the positioning rib 3 of the mounting fixture 1 and the hook portion 5 of the mounting leg piece 4, etc., the mounting fixture 1 and The lighting fixture 6 can be reliably attached to the mounting plate 11. Further, since the engaging protrusions 15 of each elastic rib 14 engage with each small circular hole 10 of the printed circuit board 7, the printed circuit board 7 is reliably positioned. Conversely, when the lighting fixture 6 is to be removed from the mounting plate 11, the lighting fixture 6 may be removed in the reverse order to the above-described procedure.

As described above, according to the lighting fixture mounting device shown in this embodiment, the lighting fixture 6 can be attached to the mounting plate 1 without using screws.
1 can be easily attached or removed.

In FIG. 2, 18 is a transparent or semi-transparent synthetic resin display plate fixed to the front part of the fixture 1.
For example, display characters indicating the noise reduction function of the tape deck are drawn on this display board, and when the noise reduction circuit of the tape deck is operating, the pilot lamp 8 of the lighting device 6 lights up, and the display board 1
The display character 8 is illuminated to indicate that the noise reduction circuit is operating. In order to supply power to the pilot lamp 8 of the lighting device 6, the printed circuit board 7 of the lighting device 6 is connected to the main printed circuit board (not shown) of the tape deck via a lead wire (not shown).

Furthermore, in FIG. 3, 16 is a level meter with a built-in light emitting diode fixed to the mounting plate 11;
17 is a push button. and level meter 16,
The mounting plate 11 to which the push button 17, lighting fixture 6, and fixture 1 are attached is the front panel of the tape deck (not shown).
mounted on.

As described above, according to the lighting fixture mounting device according to the present invention, a lighting fixture in which a light emitter is mounted on a printed circuit board can be easily and reliably mounted on a mounting plate without using screws, thereby reducing assembly man-hours. This can be significantly reduced. Furthermore, since parts such as connectors are not used, costs can be reduced.
