Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conductive hanger plate portion provided on an outer surface of a microphone case and electrically connected to a circuit board in the microphone case, and the hanger on the hanger plate portion. It is provided in a state where conduction by direct contact with the plate part is prohibited,
A conductive hanger knob electrically connected to a circuit board in the microphone, and when the hanger knob is hooked on the conductive microphone hanger, the hanger plate and the hanger knob are connected via the microphone hanger. The present invention relates to a hanger switch structure for a microphone configured to be electrically connected to.

[0002]

2. Description of the Related Art As shown in FIG. 10, a microphone 3 connected to a main body of a communication device via a cord 1 has a hanger knob 5 having a shaft portion 5a and a flange portion 5b on its back surface.
There is a structure in which the shaft portion 5a of the hanger knob 5 is inserted into the slit 7a of the microphone hanger 7 so that the microphone 3 can be hooked on the microphone hanger 7.

Then, the microphone 3 having such a configuration
In, the microphone 3 is the microphone hanger 7
There is a device equipped with a mechanism called a hanger switch for detecting that the device is hooked on.

A conventional hanger switch structure for a microphone will be described with reference to FIGS. 10 and 11, which is a sectional view taken along the line AA in FIG. As shown in FIG. 10, a hanger plate 9 made of a conductive plate is arranged on the back side of the microphone 3. Four substantially C-shaped slits 9a are formed near the four corners of the hanger plate 9, and therefore, a tongue-shaped elastic pressing portion 9b is formed inside the slit 9a.

As shown in FIG. 11, the elastic pressing portion 9b is formed in a spherical shape protruding toward the back side. A circular through hole 9c is formed in the center of the hanger plate 9. A cylindrical portion 3 in which a stepped through hole 3a is formed at a position facing the hanger plate 9 in the microphone 3.
c is formed.

An insulating ring 11 made of a cylindrical insulating material with a flange is inserted into the through hole 9c of the hanger plate 9 and the cylindrical portion 3c of the microphone 3 so as to press the hanger plate 9 from the back side of the microphone 3. . The shaft portion 5 of the knob 5 is provided on the inner cylindrical surface of the insulating ring 11.
a is inserted, and the knob 5 is screwed through the through hole 3a.
It is fixed at 3. The hanger knob 5 is made of a conductive material.

Therefore, the insulating ring 11 prevents the knob 5 and the hanger plate 9 from being brought into direct conduction with each other. On the other hand, the microphone hanger 7 is also made of a conductive material. Further, as shown in FIG. 10, the base end portion is attached to the upper part of the microphone hanger 7, and the tip end side is made of a conductive material extending in the slit 7a direction. Is provided.

Then, when the microphone 3 is hooked on the microphone hanger 7, as shown in FIG. 11, the elastic pressing portion 9a of the hanger plate 9 is inserted into the microphone hanger 7.
Dent 5 on the hanger knob 5 flange 5b
The protrusion 8a of the support spring 8 engages with c. Therefore, when the hanger knob 5 is hooked on the microphone hanger 7, the hanger plate 9 and the hanger knob 5 are electrically connected via the microphone hanger 7.

[0009]

In the above conventional structure, the mounting feeling and the holding force when the hanger knob 5 is hooked on the microphone hanger 7 are different from those of the elastic pressing portion 9b of the hanger plate 9 to the microphone hanger 7. Depends on pressing force.

However, the elastic pressing portion 9b is formed by projecting the inside of the substantially C-shaped slit 9a formed by punching the hanger plate 9 into a spherical shape. Therefore, the pressing force is substantially determined by the diameter and width of the substantially C-shaped slit, but the size of the hanger plate 9 and the relationship with the hanger knob 5 reduce the degree of freedom in design and give the desired wearing feeling. There are problems that are difficult to obtain.

Further, when the microphone 3 is hooked on the microphone hanger 7 or when the microphone 3 is detached from the microphone hanger 7, the impact acting on the microphone 3 is concentrated on the elastic pressing portion 9b, so that the elastic pressing portion 9b is not affected. There is also the problem that fatigue is fast and durability is low.

The present invention has been made in view of the above problems, and a first object thereof is to provide a hanger switch for a microphone that is comfortable to wear. A second problem is to provide a hanger switch for a microphone having improved durability.
