[Detailed Description of the Invention] Industrial Application Field The present invention is directed to LEDs used in telephones, intercoms, etc.
(Light Emitting Diode) Holding Device.

Conventional technology Conventionally, this type of LED needs to be mounted at a constant height with respect to the substrate, and for this reason, the LED is held at a constant height with respect to the substrate using a cylindrical or prismatic spacer. ing. Hereinafter, an example of the above-mentioned conventional technology will be explained with reference to the drawings.

Lead 5 of LED 51 as shown in FIGS. 3 and 4.
A protrusion 53 is provided in the middle of the two. On the other hand, the spacer 54 is formed in a cylindrical (or prismatic) shape, and the lead 5
A groove (or hole) 55 for inserting the 2 is formed.

Then, connect the lead 52 of the LED 51 to the groove 5 of the spacer 54.
Insert into 5 1. , the protrusion 53 of the +7- door 52 is connected to the spacer 54.
In this state, the lead 52 of the LED 51 is inserted into the lead insertion hole 57 of the board 56, and the bottom surface of the spacer 54 is brought into contact with the board 56.

Since the positioning between the LED 51 and the substrate 56 is performed using the leads 52 of the LED 51 and the holes 57 of the substrate 56, there is play and the LED 51 is bent, making it difficult to attach it to an accurate position. Particularly in the case of a rectangular LED 51, the bending becomes noticeable and the appearance is poor. Furthermore, since the lead 52 of the LED 51 is not held in a fixed state by the spacer 54, when the lead 52 of the LED 51 is inserted into the hole 57 of the board 56, the spacer 54 may fall off, and the LE
The lead 52 of the D51 is hidden in the spacer hole, making it difficult to see and difficult to insert into the hole 57 of the board 56. Further, since the LED 51 is not held in a state where it is not removed, if the board 51 is moved or reversed after inserting the lead 52 into the hole 57 of the board 56 and before soldering, the LED 51 will be removed from the board. 56, and by reversing the board 56 during soldering, the LED 51 may fall off the board 56.
It may fall off or float up. Soldering using a dip also has a problem in that the LED 51 is soldered in a state that it is lifted off the board 56 due to vibrations when moving the dip tank.

The present invention solves the problems of the prior art, and it is possible to easily position the LED leads with respect to the board, and also to easily position the LED leads with respect to the holes in the board. It can be inserted securely, and the L
