Description

[Detailed Description of the Invention] The present invention relates to a switch fixing structure that has a simple partial structure and can be easily attached and detached.

Conventional mounting structures include, for example, fixing the switch 1 to the support plate 2 with screws 3 as shown in FIG. 1a, or caulking the switch 4 to the support plate 6 with several protrusions 5 as shown in FIG. are equal. However, in the case of b, it is difficult to remove the switch, and it may be necessary to replace the switch when changing the pattern or repairing the telephone in the field, so it was desired that the switch be easy to attach and detach.

The present invention aims to improve these drawbacks and provide a switch fixing structure that can be easily attached and detached. The drawings will be explained in detail below.

FIG. 2 is a perspective view showing a switch fixing structure according to an embodiment of the present invention. 7 is a switch, 8 is a mounting plate, 9 is a support plate, and the mounting plate 8 is provided with two positioning protrusions 10 and one fixing protrusion 11. The fixing protrusion 11 is formed in an L-shape and has a slope 11b on its inner edge.
The support plate 9 has holes 1 corresponding to the protrusions 10 and 11.
2 and 13 are provided. Figure 3a shows the protrusion 10,1
1 is inserted into the holes 12 and 13, respectively, and FIG. 3b is a diagram when the switches are moved by the dimension A after being inserted and they fit into each other.

In FIG. 3b, the protrusion 15 of the hole 12 fits into the hole 14 of the protrusion 10 to position the switch,
A protrusion 17 is fitted into the groove 16. In this state, the tip 11a of the protrusion 11 is located at the entrance of the groove 13a of the hole 13, so the protrusion 11
When bent, the tip 11a enters the groove 13a and the inclined surface 11b abuts against the support plate 9, stopping the upward movement of the switch 7 and pressing the switch 7 against the support plate 9.
Then, the fitting between the groove 16 and the protrusion 17 is locked to fix the switch 7 to the support plate 9. To remove the switch 7, unbend the protrusion 11 and insert the tip 11a into the groove 1.
3a and return the switch 7 by the A dimension, both fittings can be released and the switch 7 can be easily removed.

FIG. 4 shows another embodiment of the present invention, in which the fixing protrusion 1
8 in the opposite direction, and the hole 19 is L-shaped. The rest is the same as the previous example.

As explained above, according to the present invention, the fitting of the switch support plate can be locked or released by bending and unbending the fixing protrusion at only one point, making it easy to attach and detach the switch and convenient for maintenance and replacement. It is.
