Conventionally, when the height of an LED mounted on a circuit board is adjusted, the length of the lead is set to be relatively long, and the lead is appropriately bent and adjusted. For this reason, not only the height adjustment is troublesome, but also the mounting of the LED is unstable. Further, when the standard of the LED to be mounted or the display position of the case is different, it is necessary to adjust the height each time, which is very troublesome.

There is also a holder for holding the LED at a predetermined height. However, this holder cannot be automatically mounted because it is a loose product. When mounting an LED on a circuit board, the LED and the holder are not connected to each other. Must be assembled at the same time,
There is a problem that it takes time and effort. The present invention has been made in view of the above points, and has been made in view of the above.
It is an object of the present invention to provide a taping LED holder that accurately holds the height of D from a circuit board and that can be automatically mounted.

[0005]

According to the present invention, there is provided an LED holder for holding an LED mounted on a circuit board at a predetermined height from the circuit board. A pedestal portion for providing the LED at a predetermined height position,
The lower part comprises two legs extending downward from the lower surface of the pedestal part at a predetermined interval, and the lower part is fixed to the tape along the longitudinal direction, and the leg part is cut at a predetermined position. The LED is taken out from the tape, mounted on the circuit board, and mounted thereon.

[0006] The taping LED holder is mounted on an automatic insertion machine, and the LED holder is cut off the leg from a predetermined position, taken out from the tape, and inserts the leg into a hole formed at a predetermined position on the circuit board. It is fixed. Then
The LED is transported above the LED holder by the mounting machine,
The lead is inserted and mounted in a hole formed in the circuit board through a slit in the pedestal portion. LED is L
The tip of the lead is soldered to a circuit pattern formed on the back surface of the circuit board in a state where the lead is placed in contact with the upper surface of the base of the ED holder. Thereby, the LED is accurately mounted on the circuit board at a predetermined height position.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a taping LE according to the present invention.
FIG. 2 is a front view in which a part of the D holder is partially cut away.
FIG. 3 is a perspective view of the LED holder of FIG.
FIG. 4 is a sectional view taken along the line III-III of FIG.
It is sectional drawing which follows VI.

As shown in FIG. 1, the taping LED holder 1 has a large number of LED holders 5 arranged at predetermined intervals along one longitudinal direction on one side (upper side) of a band-shaped mount (hereinafter referred to as “tape”) 2. Each leg 7 is adhered and fixed to the tape 2 by the adhesive tape 3. In the tape 2, feed holes 2a are formed in the center at predetermined intervals. The LED holder 5 includes a pedestal portion 6 on which the LED is mounted, and two legs 7, 7 extending downward from both left and right sides of the pedestal portion 6. The pedestal portion 6 is provided with slits 6c and 6d from the upper surface 6a to the lower surface 6b in the vertical direction at the center of the front and rear surfaces of the prism, and has a substantially H shape in plan view. Upper surface 6a of base 6
Is approximately the same size as the bottom surface of the LED 9 (FIG. 5) so that it does not protrude outward when the LED 9 is mounted, and the height h is Is a predetermined height in accordance with the mounting height (specification) of.
The width a and the interval (pitch) b of the slits 6c and 6d are L
Leads 9a and 9b extending downward from the lower surface of the ED 9 are set to be insertable.

The leads 9a and 9b of the LED 9 have different widths in order to distinguish the polarities. If the widths of the slits 6c and 6d are set in accordance with the widths, it is effective to prevent erroneous LED assembly. It is. Also, the slits 6c and 6d
Alternatively, a small hole may be used. The legs 7, 7 are opposed to each other with a predetermined interval (pitch) c, and the upper end and the lower end are connected by connecting portions 7a (FIG. 3) and 7b, respectively, to form a rectangular frame. It is formed by stamping a metal plate. As shown in FIG. 3 and FIG.
Are arranged so as to cross the center of the lower part in the left-right direction, and are integrally molded with a resin member. And LE
The size and height h of the upper surface 6a of the pedestal portion 6 of the D holder 5 and the width a and the pitch b of the slits 6c and 6d are determined by L to be used.
The setting is made in accordance with the ED standard, the specifications of equipment using the LED, and the like.

Hereinafter, a procedure for mounting the LED holder and the LED on the circuit board will be described. The taping LED holder 1 shown in FIG. 1 is mounted on an automatic insertion machine (not shown), and the tape 2 is sequentially fed through the feeding hole 2a. LE
In the D holder 5, the legs 7, 7 are cut to a predetermined length (indicated by a two-dot chain line), taken out of the tape 2, and pierced to a position where the LED 9 of the circuit board 11 is to be mounted as shown in FIG. The legs 7, 7 are inserted into the holes 12, 12, and the tips protruding from the rear surface are bent and fixed so as not to deviate. In this way, L is attached to the circuit board 11 by the automatic insertion machine.
The ED holder 5 is mounted and fixed. The pedestal portion 6 of the LED holder 5 is mounted vertically with the lower surface 6b in contact with the circuit board 11.

Next, the LED 9 is transported above the LED holder 5 by the mounting machine, and the leads 9a and 9b are inserted through the holes 13 and 13 formed in the circuit board 11 through the slits 6c and 6d of the pedestal 6. You. The LED 9 has a lower surface 9c placed in contact with an upper surface 6a of the pedestal portion 6 of the LED holder 5, and the tips of the leads 9a, 9b are
1 is soldered to a circuit pattern formed on the back surface. Thereby, the LED 9 is accurately and stably mounted on the circuit board 11 at a predetermined height from the circuit board 11.
