極３と接続する電極４とを有している。In FIG. 1, this embodiment includes a modular plug 21 that is attached to the telephone body 1, a modular connector 22 that is inserted into the modular plug 21 and connects a signal line, a solenoid 24 that moves a lock part 27, and a solenoid 24 that moves a lock part 27. A key part 29 for inputting a preset number to move the solenoid drive circuit 28 and the lock part 27.
The modular plug 21 is connected to the telephone main body 1.
The modular jack 22 has an electrode 3 that also serves as a spring and connects to the tip of the cord 9 connected inside, and a pawl 23 that is connected to a lock part 27 to semi-fix the modular jack 22. It has a recess 26 for being semi-fixed, and an electrode 4 that is connected to the cord 8 of the signal line from the outside and connected to the electrode 3 inside the modis plug 21.
次に、本実施例の動作について説明する。Next, the operation of this embodiment will be explained.

ュラジャク２２を手で差し抜くことができる。When removing the modular jack 22, enter the preset number from the key part 29, and the solenoid drive circuit 28
detects this and analyzes whether the input number is a preset number, and if the numbers match, a signal is sent from the output terminal of the solenoid drive circuit 28 to the solenoid 24 while the last input button is pressed. When the driving current flows, the lock part 27 is operated in one direction of the telephone packing machine main body of the solenoid 24, and the part of the pawl 23 connected to the lock part 27 is pulled.
The module jack 22 can be inserted and removed by hand without being caught by the pawl 23 of the recess 26.
