The method mainly comprises the fields of nuclear power stations, railways, communication, petrifaction, passenger cars, electric power and the like. Its main function is to connect and fix the cable, guarantees its high waterproof performance, fire behaviour and the electromagnetic compatibility function of requirement simultaneously. Thereby effectively forming long-term stable effective protection for the cable and the equipment.

When the existing cable, the connector and the box body are assembled, the connector is firstly installed on a wiring end of the cable, then the wiring end of the cable is inserted into the box body and is connected with a wiring terminal in the box body, and then the connector and the box body are fixed through bolts.

In the prior art, patent document CN109546609A discloses a double-locking quick-plugging electromagnetic compatible connector, in which the connection terminal of the cable has a connection piece and is connected to the connection terminal in the box body through the connection piece. When the wiring end of cable was inserted into the box, the connecting hole of connection piece was not aimed at with the binding post in the box under the many conditions, consequently need rotate the back with the connection piece for after the connecting hole on the connection piece aimed at with binding post, can accomplish the connection again with the connection piece suit on binding post.

However, when the connector is mounted, the electromagnetic shield layer of the cable is compressed and fixed to the cable connection tube of the connector by deformation of the compression ring. Under this structure, lead to between cable and the joint to be the locking structure, electromagnetic shield layer and cable conductor can't rotate for the joint promptly. Therefore, when the cable is connected with the box body, when the connecting hole in the connecting sheet is not aligned with the wiring terminal in the box body, the connecting sheet can only be rotated forcibly to be connected with the movable cable and the electromagnetic shielding layer in parallel, and the electromagnetic shielding layer is damaged easily after being rotated forcibly and deformed, so that the shielding effect on the cable is influenced, and an improved space exists.
