BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a light emitting diode for mounting a printed circuit board used for a display unit constituting an apparatus such as an electronic apparatus.

[0002]

2. Description of the Related Art In recent years, a light emitting diode mounted on a printed circuit board has been widely used as a display method of a display unit constituting an apparatus such as an electronic apparatus. FIG.
FIG. 6 is an external perspective view of a display unit of the conventional display unit.
5 is a sectional view taken along the line AA in FIG. 5, and FIG. 7 is an external perspective view of a printed circuit board portion of a display unit of the display unit. In these figures, a display window is provided on the front panel 1, and a transparent acrylic plate 2 is fixed on the back surface with an adhesive or the like. 3
Is a light emitting diode, 4 is a printed circuit board, and a plurality of light emitting diodes 3 are usually used side by side in view of the configuration of the display unit. The light emitting diodes 3 are arranged at the same height from the printed circuit board 4 and are insulated so that the lead wires 3a of the light emitting diodes 3 do not come into contact with each other. A heat-resistant tube 5 having a uniform length is inserted into the wire 3a and soldered to the printed circuit board 4, so that the transparent acrylic plate 2 can be seen through the front face. However, in this case, the integrated circuit 6 and the like other than the light emitting diode 3 on the printed circuit board 4 which constitute the circuit of the printed circuit board 4 can be visually recognized at the same time. The metal fitting 7 is provided on the printed circuit board 4. The bracket 7 has square holes 8 corresponding to the number of light emitting diodes 3.
The display portion 3b of the light emitting diode 3 can be viewed from the front, and only the display portion 3b of the light emitting diode 3 and the metal fitting 7 can be seen from the front surface of the transparent acrylic plate 2.

[0003]

However, the above-mentioned conventional structure has the following problems. Even if a plurality of light emitting diodes 3 are arranged neatly in a straight line, the light emitting diode 3 itself is supported by a thin lead wire 3a, so it is very difficult to arrange the light emitting diodes 3 neatly in a straight line, and the surface is uneven. . Further, the square holes 8 of the metal fittings 7 can be aligned with the outer shape of the display portion 3b of the light emitting diode 3 as much as possible, and the arrangement of the light emitting diodes 3 can be forcibly corrected by the square holes 8 so that they can be aligned neatly. But metal fittings 7
The display portions 3b of a plurality of light emitting diodes 3 must be incorporated into the square hole 8 at a time. In this case, if the positions of the square holes 8 and the light emitting diodes 3 are slightly displaced, the integration is very difficult. It was difficult. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned problem and to easily mount a metal fitting even when a plurality of light emitting diodes are arranged in a concave and convex manner, and to make the light emitting diodes lined up in a straight line.

[0004]

According to the present invention, in order to solve the above-mentioned problems, as many light emitting diodes as the number of light emitting diodes attached to the printed circuit board are provided with holes through which the display portions of the light emitting diodes can be seen. The first metal fitting and the second metal fitting for blindfold are provided.

[0005]

According to the present invention, in a display unit for displaying by a light-emitting diode mounted on a printed circuit board, a plurality of light-emitting diodes arranged in a concave and convex manner are formed by a first metal fitting and a second metal fitting. Since the pinching is forcibly corrected by the peephole, the light emitting diodes can be arranged neatly in a straight line, and by using two metal fittings, the fitting of the metal fitting to the light emitting diode can be performed. Incorporation can be facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. In FIG. 7, a heat-resistant tube 5 is inserted into a lead wire 3a of a plurality of light emitting diodes 3 mounted on a printed circuit board 4, as described in the prior art. The height of the light emitting diodes 3 is made uniform and the light emitting diodes 3 are insulated so that the lead wires 3a of the light emitting diodes 3 do not come into contact with each other. In this state, since the light emitting diodes 3 are supported by the thin lead wires 3a and soldered, the light emitting diodes 3 are not aligned in a straight line but are shifted and attached to irregularities.

FIG. 1 is an external perspective view of a display unit of a display unit showing one embodiment of the present invention, FIG. 2 is a sectional view taken along line BB of FIG. 1, and FIG. 3 is a plan view of a first metal fitting according to the present invention. FIG. 4 is a plan view of the second metal fitting according to the present invention. In these figures, the first metal fitting 11 is provided with square holes 12 in a number corresponding to the number of light emitting diodes 3 so that the display portion 3b of the light emitting diode 3 can be seen. Light emitting diode
The size of the display unit 3b of the light emitting diode 3 is sufficiently large so that the display unit 3b is not affected by the unevenness due to the displacement when the diode 3 is mounted on the printed circuit board 4. Therefore, one end faces of the display portions 3b of the plurality of light emitting diodes 3 arranged in an uneven manner are brought into contact with one end faces of the square holes 12 of the first metal fitting 11, and the light emitting diodes 3 are formed through the square holes 12. The first metal fitting 11 is attached to the printed circuit board 4 so that the display section 3b can be seen. The second metal fitting 13 is provided with a square hole 14 similar in size and number to the square hole 12 provided in the first metal fitting 11, and the second metal fitting 13 is attached to the first metal fitting 11. At this time, the display portion 3b of the light emitting diode 3 is sandwiched between one end face of the square hole 14 of the second metal fitting 13 and one end face of the square hole 12 of the first metal fitting 11. With this configuration, the light emitting diodes 3 can be aligned neatly in a straight line by correcting the deviation of unevenness when the light emitting diodes 3 are attached to the printed circuit board by the square holes of the first metal fitting and the second metal fitting.

When a plurality of light emitting diodes are mounted on a printed circuit board, it is natural that the mounting pitch differs depending on the purpose and purpose of display. Therefore, the square holes provided in the first metal fitting and the second metal fitting are not provided by the number corresponding to the number of the light emitting diodes, but by the total number of the light emitting diodes.
Of course, there is a possibility that a long hole can be seen through the window. Further, the shape of the light emitting diode is not limited to a square shape but may be a round shape, and these are not excluded from the scope of the present invention.

[0009]

As described above in detail, according to the present invention, in a display unit for displaying by a light emitting diode mounted on a printed circuit board, a plurality of light emitting diodes arranged two-dimensionally are provided. The light emitting diodes can be easily arranged in a straight line because they are sandwiched between the square holes of the metal fittings, and the square holes of each metal fitting have a sufficient margin by using two metal fittings. The size can be increased, and even if a plurality of light emitting diodes are arranged, it can be easily incorporated. Therefore, it is possible to provide a display unit in which the arrangement of the light emitting diode displays is beautiful and the operation efficiency is high.
