Description

[Detailed Description of the Invention] The present invention relates to a light emitting diode mounting device for mounting a plurality of light emitting diodes on a printed wiring board, and is designed to enable simple, accurate, and stable mounting of light emitting diodes.

In recent years, there have been many cases in which a plurality of light emitting diodes are attached to a printed wiring board in a row and used for displaying devices.

In this case, the mounting of the individual light emitting diodes in relation to the outer casing of the device must be maintained accurately in terms of height, perpendicularity, etc. relative to the printed circuit board.

The present invention has a simple structure and can be installed efficiently, and one embodiment thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a light emitting diode holding plate made of elastic synthetic resin, and on the upper surface of the holding plate 1 there are claws 3a that protrude inwardly from the upper end of each light emitting diode to lock the light emitting diodes 2 from both sides.

A plurality of pairs of holding pieces 4a and 4b having 3b are integrally formed in a protruding manner.

The holding pieces 4 a and 4 b are formed at a plurality of locations depending on the number of light emitting diodes to be attached.

Further, on both ends of the lower surface of the holding plate 1, engaging pieces 6a and 6b having claws 5'a and 5b protruding outward at the tips are integrally formed. Holes 8a and 8b are provided in between, through which the anode button and cathode lead wires 7a and rb of the light emitting diode 2 are inserted, respectively.

Reference numeral 9 denotes a printed wiring board, and the board 9 has holes IQ a > 10 b into which the engaging pieces 6 at 6 b of the holding plate 1 are fitted and the claws 5 a and 5 b are engaged, and a lead wire Ta of the light emitting diode 2 . , rb are inserted into the hole 11a.

11b is formed.

The structure is as described above, and the assembly will be described next. First, the holding plate 1 is inserted from above the printed wiring board 9□ by inserting the engaging pieces 6a, 6b into the holes 10a.

, 10.bl, the engaging piece 6a bends inward as shown in FIG.
When a protrudes from the back surface of the holding plate 1, the claw 5a is engaged with the engaging piece 6.
When a returns, it engages with the lower surface of the holding plate 1, and this is done in the same way even when it is turned toward the engagement piece 6b, so that the holding plate 1 is held on the printed wiring board 9.

Next, when the light emitting diode 2 is inserted from above between the holding pieces 4a and 4b of the holding plate 1, the claw 3a.

3b, the holding pieces 4a, 4b are bent outward as shown in FIG.
a t a b locks the upper surface of the light emitting diode 2 , and the light emitting diode 2 is mounted on the holding plate 1 .

Note that when mounting the light emitting diode 2 on the holding plate 1, its lead wires 7a and 7b are inserted into the holes 8a>8b of the holding plate 1, and are further inserted into the holes 11a and 11 of the printed wiring board 9.
inserted into b.

After the light emitting diode is similarly held by the other holding pieces 4 a and 4 b in this way, the lead wires 7 a and 7 b of the light emitting diode 2 are connected to the printed wiring board 9 using a general soldering method or a soldering iron. By soldering to the copper foil 12, the plurality of light emitting diodes 2 are electrically connected to the printed wiring board 90 circuit.

When connecting the lead wires 7a and 7b to the printed wiring board 9 using the solder dip method described above, there is a fear that the engaging pieces S a t 6 b protruding from the lower surface of the printed wiring board 9 may melt due to solder heat. The holding plate 1 may be made of a heat-resistant synthetic resin such as Noryl resin, and although ABS resin or the like may be slightly deformed by heat, the light emitting diode will not fall off as a whole.

As described above, the present invention can stably and reliably mount a plurality of light emitting diodes on a printed wiring board at preset positions, and therefore, when the printed wiring board is incorporated into a device, the light emitting diodes can be mounted on the outer casing of the device. The positions of the diodes correspond to each other with high precision, which has a significant effect on reducing the number of parts and costs.
