Description

[Detailed Description of the Invention] This invention relates to a mechanism for fixing a power push switch of a push-button tuner to the front panel of the tuner.

The power push switch of the push button tuner is turned on and off by pressing the tuning knob.
That is, when the tuning knob is pressed, it performs the function of operating a power switch, and when it is rotated, it moves the core back and forth within the coil to set the frequency. Therefore, in a push-button tuner, it is necessary to provide a push switch connected to the tuning shaft near the shaft of the tuning knob (tuning shaft). Conventionally, in order to attach this push switch to a tuner, as shown in FIG. and then screwed in two tightening screws E to secure it. However, when fixing with this mechanism, two screw holes had to be cut into the edge of the push switch C, making the tapping operation cumbersome. Another disadvantage was that securing the switch requires tightening two screws, which is time-consuming. Furthermore, since two screws are required, there is also the inconvenience of a large number of parts.

This invention features a push switch fixing mechanism for a push button tuner that allows the push switch to be attached to the front panel with just one screw by engaging the locking piece on the push switch side with the notch in the tongue provided on the front panel. The purpose is to provide

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

Figures 2 and 3 show first and second embodiments of the present invention, in which the front plate of a switch is fixed to the back of the front panel. That is, the front panel 1 of the push button tuner
A tuning shaft 2 is attached so as to be movable forward and backward, and a mounting hole 4 for mounting a push switch 3 is provided diagonally above the tuning shaft 2. Next to this attachment hole 4, a recess (or hole may be used) 5 for positioning is provided. Further, a tongue piece 6 is provided below the mounting hole 4 in the front panel and projects at right angles toward the back side of the front panel 1, and a notch 7 is formed here.
is formed. As this notch 7, the second
As shown in the figure, even if it is groove-shaped with one end open,
Alternatively, a slit-like structure as shown in FIG. 3 may be used. On the other hand, there is a screw hole 9 with a female thread in the upper part of the front plate 8 of the push switch 3, and a positioning projection 10 is provided next to the screw hole 9. Furthermore, a locking piece 11 is provided on the lower edge of the front plate 8 to protrude downward.

In addition, an operating rod 12 for ON/OFF operation is protruded from the center of the switch, and a notch 13 is provided at the tip of the rod. 14.

In order to attach the push switch 3 to the front panel 1 according to the first and second embodiments, the locking piece 11 of the push switch 3 is first inserted into the notch 7 provided in the tongue piece 6 of the front panel 1.

Next, the notch 13 provided at the tip of the operating rod 12 of the push switch 3 is fitted into the groove 14 of the tuning shaft 2. After that, align the positioning protrusion 10 provided on the switch 3 with the recess 5 provided on the front panel, insert the screw 16 into the mounting hole 4, and screw this screw 16 into the screw hole 9 of the switch 3. , tighten the front panel and switch.

Next, a third embodiment of the present invention will be described with reference to FIG. In this second embodiment, the front plate of the switch is fixed to the front side of the front panel. That is, the front panel 1 of the push button tuner 3 is provided with a screw hole 4A with a female thread in the diagonal upper part, while the upper part of the front panel 8 of the push button switch 3 is provided with a mounting hole 9A.

In order to attach the push switch 3 to the front panel 1 according to the second embodiment, the locking piece 11 of the push switch 3 is first inserted into the notch 7 provided in the tongue piece 6 of the front panel 1. Next, the notch 13 provided at the tip of the operating rod 12 of the push switch 3 is fitted into the groove 14 of the tuning shaft 2. After that, a positioning protrusion 10 provided on the switch 3
and the recess 5 provided in the front panel, insert the screw 16 into the mounting hole 9A, screw this screw 16 into the screw hole 4A of the front panel 1, and tighten the front panel 1 and the switch 3. .

As described above, according to the present invention, it is possible to fix the push switch to the front panel using only one screw, which reduces the number of installation steps and also reduces the number of parts by omitting the screw. There is an effect. Furthermore, when manufacturing parts, it is only necessary to erect one tap on the switch side, which has the advantage of simplifying manufacturing work.

It should be noted that if the front panel and the switch are provided with positioning recesses and protrusions as in the illustrated embodiment, there is an effect that the two can be fixed more accurately. Furthermore, if the notch 7 is made into a slit as shown in FIG. 3, the locking piece 11 will not move in the lateral direction.
Fixation becomes more reliable.
