The on-off of signals in the circuit is controlled by the insertion and separation of the contact pin contact element and the jack contact element; the plug insulator assembly and the socket insulator assembly are the same in mounting size, free combination of different modules can be achieved, the hole cavities are various in types, contact pieces for mixing signals such as high frequency, low frequency, power and optical fibers can be mounted at the same time, through holes for mounting the air channel assembly are reserved, different using requirements of customers are met, and the air channel assembly is designed into mutually independent structures and does not influence each other.

The principle and the implementation of the present invention are explained herein by using specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope. In summary, the content of the present specification should not be construed as a limitation of the present invention.
