Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light emitting diode fixing device, and more particularly, it is an object of the present invention to provide a light emitting diode fixing device that absorbs errors in each component and enables uniform mounting and fixing.

In stereo receivers and the like, light emitting diodes are often used as display elements due to design and power consumption considerations.

However, since the light emitting diode has a special shape and its head must be inserted into a hole in the front panel so that it can be seen from the front, it must be accurately mounted and fixed in the correct position.

The present invention has been developed in view of the above points, and will be described below based on embodiments and with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention, and FIG. 2 is a rear view thereof, in which 1 is a front panel having a hole 2, and 3 is a head 4 inserted into the hole 2 of the front panel 1. 5 is a printed circuit board to which the legs (terminals) 6 of the light emitting diode 3 are connected and fixed with electrical and mechanical strength, and 7 is a molded member fixed to the front panel 1.

Thus, the molded member 7 has a hole 8 having a larger diameter than the hole 2 of the front panel 1, a flange portion 10 for preventing light leakage from the body portion 9 of the light emitting diode 3, and a front surface of the printed circuit board 5. It integrally includes four contacting bosses 11 and a locking piece 13 having a claw 12 that contacts the rear surface of the printed circuit board 5.

Incidentally, the printed circuit board 5 has two parts as shown in FIG.
It has a dimension smaller than the distance between the two locking pieces 13.

Therefore, between the printed circuit board 5 and the locking piece 13,
A gap is created to provide freedom in the vertical direction.

When assembling, first align the holes on the back side of the front panel 1 and attach the molded member 7. Then, using the elasticity of the locking piece 13, align the light emitting diode 3 fixed to the printed circuit board 5 with the arrow. When inserted in direction B, the locking pieces 13 are pushed apart by the elasticity.

When the head 4 of the light emitting diode 3 is inserted into the hole 2 of the front panel 1 through the hole 8 of the molding member 7, the return force of the locking piece 13 in the direction of arrow A causes the light emitting diode 3 to
is attached and fixed in a predetermined position together with the printed circuit board 5.

The light emitting diode 3 is fixed by attaching the printed circuit board 5 to the boss 11.
and the locking pieces 13, and are held together.

Since the light emitting diode 3 and the printed circuit board 5 are only held between each other, the light emitting diode 3 and the printed circuit board 5 can be moved relatively freely in the vertical and horizontal directions.
The positioning of the light emitting diode 3 and the head 4 of the light emitting diode 3 can be easily performed, and manufacturing errors can be absorbed.

Further, the adjustment in the front-back direction is performed using the elastic force of the printed circuit board 5.

That is, the light emitting diode 3 is connected from the surface of the printed circuit board 5.
The distance to the head 4 is sometimes set to a predetermined value when soldering, but when mounting and fixing, a dimensional error may occur due to the relationship with the boss 11 and the like.

However, since the printed circuit board 5 has elasticity, the dimensional error can be absorbed, and the dimensional adjustment in the front-rear direction can be performed accurately.

Since the light emitting diode fixing device according to the present invention formed as described above uses the printed circuit board 5, it has the advantage that the electrical connection between the terminal 6 of the light emitting diode 3 and the lead wire 14 is easy. have

In addition, since the fixation is performed only by clamping, and there is freedom in the front and back, left and right, and up and down directions, there is an advantage that dimensional errors can be fully absorbed, and the light emitting diode 3
It has the advantage that it can be easily replaced.

Further, the light emitting diode fixing device according to the present invention has a simple structure and good workability, so it is practical and has various advantages such as being useful for reducing costs.
