Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a button switch in a radio, stereo amplifier, cassette deck, or similar electronic equipment.

Conventionally, a bushing switch button in the electronic device has a bushing knob 1 as shown in FIG. 2 directly connected to a bushing shaft extending from a bushing switch body disposed inside the device.

That is, the connecting end of the bushing knob 1 is integrally formed with a frame 2 that fits into the bushing shaft of the bushing switch body. Therefore, when this bushing knob 1 is connected to the bushing shaft, the knob 1 will be connected to the bushing shaft. It became immovable in any direction, up, down, left or right with respect to the bush axis.

According to such a conventional bushing switch button, when the bushing knob 1 is connected to the bushing shaft of the bushing switch body, its axial center is perfectly positioned.

Therefore, if there is an error in the installation of the design panel 3 on the front of the electronic device as shown in Figure 1, or in the installation of the switch body to the chassis, there will be a misalignment between the bushing knob 1 and the knob hole in the design panel 3. This has the disadvantage that the bushing knob gets caught on the side of the knob hole in the design panel, making it difficult to turn the bushing knob on and off smoothly.

Therefore, an object of the present invention is to eliminate the drawbacks in the structure of the conventional button switch button described above, so that even when the center of the button shaft of the switch body and the center of the knob hole of the design panel do not exactly match, The object of the present invention is to provide a structure for a button switch that enables smooth operation.

Hereinafter, the structure of the bushing switch button according to the present invention will be described in more detail with reference to the preferred embodiments of the present invention shown in the accompanying drawings.

3 and 4 show the structure of a bushing switch button according to the present invention.

The structure of this bushing switch button consists of a joint 6 connected to a bushing shaft 5 extending from a bushing switch body 4, and a bushing knob 1 connected to the joint so as to be movable vertically and horizontally.

More specifically, the joint 6 has a frame body 2 which is surrounded on the top and bottom and front and back, and a bushing shaft 5 is attached to the rear wall of the frame body.
An open lower part is formed to accommodate the receiver.

In addition, protrusions 8 a and 8 b are formed on the inner surfaces of the earthen wall and the lower wall of the frame, respectively, and these protrusions allow the bushing shaft 5 to be fitted into the frame 2 through the open lower part. At this time, the bushing shaft 5 is engaged with a groove 9 formed around the bushing shaft 5 to achieve mutual connection.

On the other hand, on the front side of the frame body 2, there are flanges 10 a , 10 formed at the connecting ends of the bushing knobs 1 and projecting upward and downward.
Groove portion 11 that fits and holds b in a horizontally slidable manner.
A connecting portion 12 having all b is formed.

A hole 14 is formed in the center of the rear wall 13 of this connecting part 12, and the hole 14 is formed so that the bushing knob 1 can be inserted into the connecting part 1.
2. When the bushing knob 1 is fitted and connected by sliding as shown by the arrow 15 in FIG. Uke accepts 16.

This protrusion 16 is small compared to the size of the hole 14,
Therefore, the bushing knob 1 produces a moderate play with respect to the connecting portion 12 of the joint 6.

Further, when the bushing knob 1 is fitted into the connecting part 12, the notch part 17 formed to avoid the rod part of the bushing knob is also formed to be relatively thicker than the rod part.

Therefore, from these configurations, the bush knob 1 is connected to the joint 6.
It is possible to freely move vertically, horizontally, and horizontally with respect to the connecting portion 12 within the range where the play occurs.

As a result, according to the configuration of the bushing switch button of the present invention, even if the central axes of the bushing knob hole in the panel 3 and the bushing shaft 5 of the bushing switch body 4 do not exactly match, the discrepancy can be corrected by adjusting the bushing knob. This can be corrected by vertically and horizontally moving the joint 6 of No. 1.

Therefore, the bushing knob 1 does not get caught in the bushing knob hole in the panel, and the bushing knob can operate extremely smoothly, and there is no need to accurately center the bushing shaft and the panel knob hole as described above. This also improves work efficiency in assembling electronic equipment.
