Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a plug connector that can be detachably attached to a microphone body. More specifically, this invention relates to a plug connector that can be detachably attached to a microphone body. More specifically, it is a plug connector that does not generate contact noise when the microphone body and the plug connector are attached and detached. Regarding microphone plug connectors.

[Technical background of the invention] Generally, the main body of a vocal microphone is provided with a socket member that includes three male contacts for positive, negative, and grounding, and a mixer, amplifier, etc. are connected to this socket member. Alternatively, a plug connector having a cord to be connected to a reproduction device such as a speaker is detachably fitted. According to this, 1
Although it is convenient for handling because you can selectively use a number of microphones with the cord, and the microphone and cord can be separated as necessary, when the playback device is turned on, the plug connector Contact noise occurs when the microphone is attached and detached. The instantaneous input of this contact noise is large and unpleasant, and in some cases, there is a risk of damaging the playback device. Therefore,
Conventionally, each time a plug connector and a microphone body are connected or disconnected, the power to the playback device is turned off or the attenuator is set to infinity to disable the playback device.

[Purpose of the invention] Therefore, the purpose of this invention is to connect and disconnect from the microphone body without causing contact noise by simply pressing the plug connector or the pressing knob for the connection lock provided on the microphone body. The purpose of the present invention is to provide a microphone plug connector that allows for

[Example] Hereinafter, an example of this invention shown in the drawings will be described in detail.

As shown in FIG. 1, the microphone main body 3 has a cylindrical grip portion 1,
A sound collection section 2 is provided at the tip, and on the other hand,
At the rear end, a socket member A including three signal pins, a positive male contact 4, a negative male contact 5, and a grounding male contact 6, is provided as shown by the dotted line in the figure, similar to the conventional microphone body. .

According to this invention, the plug connector 7 can be detachably fitted into the socket member A of the microphone body 3 without generating contact noise. That is, this plug connector 7 has a cylindrical housing 8 formed to fit into the socket member A, and one end of the housing 8 has a cylindrical housing 8 that corresponds to each of the male contacts 4 to 6. A positive female contact 9, a negative female contact 10, and a grounding female contact 11 are provided, and
A lock knob 12 is provided at the top of the housing 8. This lock knob 12 has a nozzle support member 1 whose one end is pivotally supported by the housing 8.
A protrusion 14 is provided on the upper surface of the knob support member 13 to engage with a recess (not shown) formed in the socket member A. The knob support member 13 is elastically supported by a knob return spring 16 provided in a recess 15 in the housing 8 so as to be movable downward. The upper end of the contact pin 17 is in contact with the lower surface of the other end of the knob support member 13 . The lower end of this contact pin 17 has a recess 15
It is located in a switch case 18 that is integrally provided with the housing 8 at the lower part of the switch case 18 . Inside the switch case 18 is a conductive contact pin return spring 2 whose one end is fixed to a rivet 19 and which always elastically pushes the contact pin 17 upward.
0 is set. A lead wire 21 connected to the negative female contact 10, for example, is connected to the rivet 19. Further, the switch case 18 is provided with a rivet 22 so as to come into contact with the spring 20 when the contact pin 17 is pushed down against the elastic force of the return spring 20. A lead wire 23 connected to the positive female contact 9, for example, is connected to the rivet 22.

A horizontal groove 24 is provided on the rear end side surface of the lock knob 12.
A malfunction prevention slide stopper 25 provided on the housing 8 is fitted into the horizontal groove 24. This slide stopper 25
is a stopper knob 26 protruding onto the housing 8.
By sliding the housing 8 in the axial direction, the fitting with the lateral groove 24 is released. In addition, the lead wires 21 and 23 and the grounding female contact 11
The lead wires 27 connected to the connector are both connected to a plug jack 28 in a known manner.

Next, the case of connecting this plug connector 7 to the microphone main body 3 will be explained. First, slide the stopper knob 26 from the position shown in FIG.
2 can be pressed downward. When the lock knob 12 is pressed downward against the elastic force of the knob return spring 16, the contact pin 17 descends against the elastic force of the return spring 20, and the return spring 20 releases the rivet 22. as shown by the dotted line in Figure 2. As a result, the lead wire 21 is electrically connected to the lead wire 23 via the rivet 19, the return spring 20, and the rivet 22. Therefore, by inserting the plug connector 7 into the microphone main body 3 in this state, no contact noise is generated. Then, when the pressing force of the rib 12 is released, the return spring 20 returns to the position shown by the solid line in FIG. 2, and the conduction between the lead wires 21 and 23 is interrupted. On the other hand, when removing the plug connector 7 from the microphone main body 3, the same operation as described above is performed to short-circuit the lead wires 21 and 23, and the plug connector 7 can be removed without generating noise. Note that in the case of a capacitor type microphone etc. that uses an external power supply, it is necessary to short-circuit the positive side lead wire 23 and the negative side lead wire 21 as in the above embodiment, but in the case of a dynamic type microphone etc. 2
All you have to do is short-circuit the two lead wires.

Further, the slide stopper 25 is provided to prevent the knob 12 from being pressed by mistake when the microphone main body 3 and the plug connector 7 are connected. By forming a groove on the back surface of the transverse groove 25 and providing the housing 8 with a spring that elastically engages with this groove, the fitting and disengagement with the transverse groove 24 can be maintained in a clickable manner.

[Effects] As is clear from the above description of the embodiment, according to this invention, predetermined lead wires are short-circuited in connection with the operation of the lock knob that is pressed when attaching to and detaching from the microphone body, so noise generation is prevented. It is possible to completely prevent this, and there is no need to disable the reproducing device each time it is attached or detached, unlike in the conventional case, which is extremely convenient in practice.

In the above embodiment, the plug connector 7 is inserted into the microphone main body 3 by pressing down the knob 12 with a finger.
If the projection 14 is configured to be pushed down by the inner wall surface of the socket member A of the microphone body 3 and then elastically engaged in a recess (not shown) when inserting the knob, it is necessary to press the knob with your finger. There isn't.
