Abstract

PURPOSE:To hold a plurality of LEDs vertically and horizontally and to enhance their positional accuracy by providing a substrate connector having an elastic section and a boss, providing a LED upper retainer, and providing a hook and a removal preventive protrusion rib at an end. CONSTITUTION:Sidewalls 1a, 1b and an intermediate holding member 1c are composed of elastic members, and pressed to be broadened at the time of inserting LEDs. A holder 1 is provided horizontally, a hook securing rib 14 is provided at an upper retainer 5, a hook 4 to be connected to the holder 1 is provided at its end, and a recess is formed at the retainer 5. When a lower LED 9 is first inserted, a protrusion 3 and a round LED holder 13 are pressed to be broadened, and an upper LED 9 is thereafter pressed to be held from above. Thereafter, the retainer 5 is connected to prevent it from floating. Since the LED can be displayed in a small space and the LED can be accurately positioned, problems, such as a light leakage of the LED, wrong assembling and insertion in a housing can be solved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an LED fixing device suitable for vertically and horizontally arranging a plurality of LEDs on a single substrate such as a television receiver.

[Conventional technology]

In the conventional device, as described in Utility Model Application No. 60-166157, an LED lamp is fitted into a semi-cylindrical holding part using a hook part using a hinge part. It is not possible to install the LED, and there is no positioning in the left and right direction.
Since the claws are not prevented from falling inward, there is a risk that the cover arm may come off the claws.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into consideration the arrangement and holding of a plurality of LEDs vertically and horizontally with respect to the substrate (there was a problem that the LED position accuracy 9 was poor in workability and the hook part easily came off).

An object of the present invention is to hold a plurality of LEDs vertically and horizontally to improve the positional accuracy of the LEDs (preventing the lamp from floating).

[Means for solving problems]

The above purpose has an arrow-shaped board fitting part with an elastic part and a boss, and the holding part is vertically and horizontally aligned.

A plurality of cylindrical holding parts are provided, and the holding parts and a hinge are provided.

This is achieved by providing an upper side portion above the LED connected at a screw portion, and providing the tip portion 5 with a hook that fits into the holding portion and a protrusion to prevent the hook from slipping off.・[Function] When installing the LED, the board fitting part is inserted into the board, and the LED is installed in order from the lower holding part.
When the ED is installed, the hook is fitted into the lip to prevent the hook from coming off, and the LED is fixed to each holding part.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.
This will be explained from the diagram. The LED mounting device of the present invention includes an arrow-shaped board fitting part 8 that fits with the board 12, a board positioning boss 7 provided in front of the arrow-shaped board fitting part 8, and a pair of left and right protrusions provided in the vertical direction. 3 and a semi-cylindrical round LED holding part 13. The holding part 1 has a first side wall 1α, a second side wall 1h, and an intermediate holding member 1c.

Recesses are provided in the side walls 1α, IA and the intermediate holding member 1c, depending on the shape of the LED.

It has a shape similar to the round LED holding part 13 and the square LED holding part 2.

The side walls 1α, IA and the intermediate holding member 1c are made of elastic members, and are designed to be expanded when the LED is inserted. Furthermore, a hook fixing lip 14 is provided on the holding part 1 which also forms the above-mentioned shape in the horizontal direction, and on the upper holding part 5 connected to the holding part 1 through the hinge part 6. A hook portion 4 that fits into the holding portion 1 is provided. The upper holding part 5 is also provided with a recessed part.

Further, a square LED holding part 2 is provided in the holding part 1 so that a square LED can also be attached to the holding part 1. First, lower LED 9
When inserting the LED, the protruding part 3 and the round LED holding part 15 are elastic, so they are pushed apart, and then the upper LED is inserted.
Press and hold 9 from above. Thereafter, to prevent the LED 9 from floating, the upper presser 5 is fitted into the holding part 1 using the hook part 4. According to the invention.

The LED 9 can be easily held vertically and horizontally on the substrate 12. Furthermore, the upper presser 5 has the effect of accurately aligning the position of the LED 9 and the hole of the casing 10. Furthermore, even if downward force is applied to the upper valve part 5 during work as shown in Fig. 4, the hook 4 will come off because the holding part 1 is sandwiched between the hook fixing lip 14 and the hook 4. Never. Although this embodiment is a device that holds two LEDs vertically and horizontally, it is possible to fix three or more LEDs by providing a continuous holding section. It is also effective for attaching cylindrical or prismatic electronic components (such as light emitting diodes) other than LEDs.

〔Effect of the invention〕

According to the present invention, since multiple LEDs can be held vertically and horizontally, the LEDs can be displayed in a small space and the position of the LEDs can be accurately displayed. This has the effect of solving problems such as poor insertability.
