Description

[Detailed description of the invention] The present invention relates to a component holding device, and is particularly applicable to work associated with attaching display parts such as multiple light emitting diodes and lamps to a chassis board, and assembly work of attaching a cabinet to a board assembly. It is an object of the present invention to provide a component holding device configured to easily perform the following operations.

Currently, in devices such as tape recorders, light emitting diodes and the like are used as display components that fit into openings in device cabinets and can be observed from the outside.

This light emitting diode needs to be mechanically fixed to the cabinet and electrically connected to a board located away from the cabinet.

A conventional mechanism for holding light emitting diodes in a cabinet and chassis is constructed as shown in FIG.

In the figure, a light emitting diode 1 has its lead 2 a
, 2b are inserted through the through hole of the rubber bushing 3 and further inserted into the hole of the board 4 and soldered, and the light emitting part 1a is placed on the top surface of the bushing 3 and attached to the board 4.

Further, the light emitting portion 1a partially fits into the opening 5a of the cabinet 5.

Another light emitting diode 6 is also mounted using a bushing 7 in the same way as the light emitting diode 1 described above.

Since a bushing is used for each light emitting diode, especially when mounting a large number of light emitting diodes on the same board, it is necessary to pass many leads through the bushing through holes one by one, making the work cumbersome. There was a drawback.

Further, the bushing has the role of determining the position of the light emitting part with respect to the substrate 4 and preventing the pair of leads from coming into contact with each other.
It is placed on top.

For this reason, when the lead is inserted into the hole in the board, the light emitting diode is unstable to hold, making it impossible to use a lead cutter, and also making it impossible to solder with flow solder, resulting in poor workability. was there.

Furthermore, due to variations in soldering work, it becomes difficult to position the light emitting portion of each light emitting diode to fit into the opening of the cabinet, resulting in poor workability.

For this reason, the above method of holding light emitting diodes is actually limited to cases where extremely short bushings are used or when a small number of light emitting diodes are used.

The present invention eliminates the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

FIG. 2 is an exploded perspective view of one embodiment of the component holding device according to the present invention, and FIGS. 3 and 4 are respectively the I in FIG.
FIG. 2 is a cross-sectional view taken along a vertical plane including lines II-III and I-IV.

In FIG. 2, the light emitting diode holding member 10 has a substantially U-shape and is integrally molded from synthetic resin.

The holding member 10 includes a pair of hanging arm portions 10a, 10b,
It consists of a horizontal frame portion 10C1 and a side wall portion 10d.

Reference numeral 10e denotes an elastic arm section, which is formed between a pair of notches in the hanging arm section 10a, and has a locking claw 10f formed at its lower end.

The other hanging arm part 10b also has an elastic arm part 10g and a locking claw 10h.

Further, the horizontal frame portion 10C has a convex frame 101 and a plurality of stepped holes 10j.

The shape and dimensions of the concave stepped portion 10k of the stepped hole 10j are as follows:
As shown in FIGS. 3 and 4, the light emitting portion 11a of the light emitting diode 11 is properly fitted and held without any play.

Further, the dimensions of the hanging arm portions 10 a and 10 b are determined in consideration of the distance between the board 12 and the cabinet 13 in the assembled state of the equipment.

The substrate 12 has a pair of claw engaging holes 12a, 12b, and two holes 12C, 12d corresponding to each stepped hole 10j.
...... is the perforation.

Next, the assembly work order when using the above-mentioned holding member 10 will be explained.

First, the pair of elastic arms 10e and 10g are deformed inward, and the locking claws 10f and 10h are inserted into the holes 12a.
, 12b.

Thereby, the holding member 10 has hanging arm parts 10a, 1
0b and the lower end surfaces of the side wall portions 10d are fixed to the substrate 12 by making them contact the substrate.

Next, the plurality of light emitting diodes 11 are connected to the leads 14 a
, 14 through the stepped hole 10j from the b side, and each lead 14
a, 14b are inserted into the holes 12C912d, and the free ends protruding toward the lower surface of the substrate are bent, and the light emitting part 11a is fitted into the concave stepped part 10k.

In this state, the plurality of light emitting diodes 11 are held relatively stably with respect to the substrate 12.

The above operation is easier and faster than the conventional method using rubber bushings, even when a large number of light emitting diodes are to be installed.

Therefore, the incomplete assembly is subjected to a flow solder machine and each folded portion is automatically soldered without causing any inconvenience such as misalignment of the light emitting diode.

As a result, the light emitting portion 11a of each light emitting diode 11 is accurately positioned and fixed relative to the substrate 12, as shown in FIGS. 3 and 4.

Furthermore, the incomplete assembly can be passed through a lead cutter without causing any inconvenience, and the portion of the lead that protrudes excessively toward the lower surface of the substrate is automatically cut and removed.

Still further, since the pair of leads of each light emitting diode is held in an expanded state, the leads are prevented from shorting without the use of special insulating means.

Next, as shown in FIGS. 3 and 4, the opening 13a of the cabinet 13 is fitted into the frame 10i, and the cabinet 13 is fixed to the substrate 12.

At this time, there is no problem such as misalignment of the light emitting portion 11a of each light emitting diode 11, so this work is also easily performed.

In addition, in the above embodiment, the holding member 10 is attached to the locking claw 1.
Although the holding member 10 is fixed to the substrate 12 using 0 f and 10 h, the present invention is not limited thereto, and the holding member 10 can also be fixed to the substrate 12 using screws or the like.

Furthermore, the device of the present invention is applicable not only to light emitting diodes but also to lamps and the like.

As described above, the component holding device of the present invention is provided with a convex frame that fits into the part facing the cabinet opening, and is electrically connected to the board within this convex frame. A plurality of stepped holes for fitting and holding a plurality of electrical components are provided, a leg is provided to separate the cabinet and the board, and a lock is provided on the leg for directly fixing the cabinet to the board. Since the claws are integrally provided, when multiple parts are installed in the cabinet, each part fits in the stepped hole and is securely held in position. There is no variation, there is no need for rubber bushings as in the past, and it is electrically connected to the board, so multiple parts can be assembled by simply fitting the convex frame into the cabinet opening. At the same time, it can be installed accurately on the cabinet, and even if an external force is applied to the cabinet or the board, the cabinet and the board are mechanically fitted together by the holding member, so there is no possibility of mutual displacement. Without,
As a result, this external force does not directly act on the parts, so the parts are not damaged, and multiple parts can be attached to the board without difficulty.Furthermore, the flow soldering equipment and lead cutter It has features such as being able to be applied without any problems and improving work efficiency.
