Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a holder for a light emitting element used when attaching a display light emitting element to a substrate.

[Conventional technology]

2. Description of the Related Art Some electronic devices such as television receivers are configured such that a light emitting element used for channel display etc. is attached indirectly or directly to a board (printed board) using a holder.

One method for attaching a light emitting element to a printed circuit board using a holder as described above is to attach a light emitting element 2 to a sub-board 3 using a holder 1, as shown in FIG. Then, this sub-board 3 is attached to a printed circuit board 4, the lead terminals 2B of the light emitting elements 2 are electrically connected to the printed circuit board 4, and the light emitting section 2A is mounted so as to face the opening 5A of the panel 5.

Furthermore, the method of using a light emitting element holder (Utility Application No. 59-38730) proposed earlier by the present applicant is
As shown in FIG. 6, the holder 6 is attached to the printed circuit board 7. Then, the light emitting part 8A of the light emitting element 8 is held in the holding part 6A of this holder 6, and the lead terminal 8B is electrically connected to the printed circuit board 7.
In this method, the light emitting section 8A is attached so as to face the opening 9A of the panel 9.

[Problem that the invention attempts to solve]

The configuration shown in FIG. 4 uses the sub-board 3 to attach the light-emitting element 2 to the printed circuit board 4, so
It is necessary to attach the sub-board 3 to the printed circuit board 4 (mechanically fixing it and electrically connecting it), which makes the structure complicated and the assembly process complicated.

Further, the configuration shown in FIGS. 5 and 6 has a holder 6
There are problems such as the large size and limited usable range.

This idea was made in view of the above-mentioned problems, and it is a holder for light emitting elements that can be easily attached to a printed circuit board without the need for sub-boards, wiring, etc., and requires only a small space. This is what we provide.

[Means for solving problems]

Figures 1a and b are perspective views and back views showing one embodiment of this invention, Figures 2a and b are explanatory diagrams showing how a light emitting element is supported by a holder, and Figure 3 is a partial cross section showing how the holder is used. It is a diagram.

In these figures, reference numeral 11 indicates a holder mounted on the substrate, and an element mounting portion 11A and a pair of holes 11B are provided on the upper front side of this 11. The hole 11B faces the rear surface of the holder 11, and a lead terminal guide surface 11C is provided extending from above to below in a direction perpendicular to the hole 11B. Further, at the bottom of the holder 11, a pair of engaging portions 11D, 1 projecting left and right from the base.
1D is provided, and multiple dowels 1 are placed on the bottom of the base.
1E is provided, and this dowel 11E is provided with a claw 11F for preventing it from coming off. Note that 11G is a rib constituting a part of the base of the holder 11, and the guide surface 11C is separated into left and right sides by this rib 11G. Also, rib 11
As shown in FIGS. 1b and 1d, G is formed to be slightly narrower than the distance d between the holes 11B and 11B through which the lead terminals are inserted, and extends left and right in the base portion to form the lead terminals 12B. is an engaging portion 11D that is locked, and the inner surface of the protruding portion of this engaging portion 11D is formed to be slightly higher than the guide surfaces 11C, 11C.

Reference numeral 12 denotes a light emitting element, which is composed of a light emitting section 12A and a pair of lead terminals 12B.

Reference numeral 13 denotes a printed circuit board, which is provided with an opening 13A through which the dowel 11E is inserted, and a hole 13B through which the lead terminal 12B is inserted.

Reference numeral 14 designates a panel for electronic equipment, etc., and is provided with an opening 14A through which the light emitting section 12A faces.

[Effect]

Next, the operation of attaching the light emitting element 12 to the printed circuit board 13 using the holder 11 of this invention will be explained.

First, as shown in FIG. 2a, when the lead terminal 12B of the light emitting element 12 is inserted into the hole 11B of the holder 11, the light emitting part 12A can be positioned in the element mounting part 11A.

Next, using the guide surface 11C, lead terminal 12B
The pair of lead terminals 12B are separated by the rib 11G, and the tip of the lead terminal 12B is slightly opened and engaged as shown in FIG. 1b. When the part 11D is locked, the locked state is maintained by the elasticity of the lead terminal 12B, and the light emitting element 12 can be supported by the holder 11 as shown in FIG. Similarly, it is ready to be mounted on the printed circuit board 13. That is, when the lead terminal 12B is inserted into the hole 13B and the dowel 11E is inserted into the opening 13A in the state shown in FIG. The light emitting element 12 can be attached and the lead terminals 12B can be soldered to the wiring of the printed circuit board 13.

Then, when this printed circuit board 13 is attached to a predetermined position of an electronic device, the light emitting section 12A is attached to the panel 1.
4 opening 14A.

In the above embodiment, if the lead terminal 12B of the light emitting element 12 is relatively hard and difficult to deform, the rib 11G separating the lead terminal 12B from short-circuiting may not be provided.

[Effect of idea]

As explained above, the light emitting element holder of this invention inserts the lead terminal of the light emitting element into the hole of the holder, bends it along the guide surface, opens the tip slightly, and locks it in the engaging part. This has the advantage that the light emitting element and the holder can be integrated, and the light emitting element can be attached extremely easily and reliably. Furthermore, since the structure is such that the light emitting element can be mounted on the board in this attached state, the light emitting element can be mounted on the board using only a holder, and the light emitting element and the board can be electrically connected without using wires or the like. Furthermore, since the holder supports only one light emitting element, other light emitting elements or electronic components can be freely replaced, and the number and spacing of the light emitting elements can be freely set.
