Through the technical scheme, the hinge line and the aviation socket are tightly matched to realize insulation and sealing of the hinge line in a low vacuum environment, and meanwhile, the locking and looseness prevention of the connecting device can be realized through the locking spring and the locking tail pipe.

For example, the taper angle of the conical surface may be 10 °, and the conical surface has high surface accuracy.

According to one embodiment of the application, the stress cone may be made of silicone rubber, and is conical overall with a taper angle of 10 °.

Specifically, the conical surface of the stress cone is tightly matched with the conical surface (conical hole) in the epoxy socket, so that the sealing and insulation between the hinge line (plug) and the epoxy socket are realized. Under the action of the compression unit, the stress cone is wholly compressed.

That is, the limiting groove can limit the movement of the compression ring in the epoxy socket to translational movement, and can prevent the compression ring from rotating.

The epoxy socket has high strength to prevent being knocked.

According to one embodiment of the application, the epoxy socket 2 is provided with external threads, the locking tail pipe 8 is provided with internal threads, and the external threads and the internal threads are matched to realize the connection of the locking tail pipe 8 and the epoxy socket 2.

That is, the internal and external screw thread can be matched to realize the integral compression of the connecting device.

Specifically, the epoxy socket and the transition joint can be prefabricated in advance, and the epoxy socket is installed in a die for manufacturing the zero-flux module and the transition joint is connected with a zero-flux coil in the module when the zero-flux module is manufactured. The epoxy sockets and transition joints become part of the module after the zero flux module is fabricated. When the plug is manufactured, firstly, the insulated rubber-insulated wire of the hinge line is stripped for a certain length, then the locking tail pipe, the locking spring, the compression ring, the stress cone and the stop ring are sequentially sleeved on the cable, silicone oil can be smeared for lubrication in the process of sleeving the cable on the stress cone, then the wire pressing head of the hinge line is in pressure connection with the hinge line, and finally, the stop ring and the stress cone are moved to the designated position. Thus, the plug assembly is completed.

During installation, the cone cavity in the epoxy socket and the stress cone on the plug can be cleaned, then the stress cone is smeared with silicone oil on the cone cavity and the stress cone, and then force is transferred to the locking spring through the threaded fit on the locking tail pipe and the epoxy socket, so that the stress cone is in a compressed state through the compression ring.
