Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention. Referring to the drawings, like numbers indicate like or similar elements throughout the views. The described embodiments are only some, not all embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-8, an easy-to-detach sealed connector with enhanced stability comprises a socket and a plug, both the socket and the plug are provided with a housing 1 and a base 2, a pin 7 or a jack 4 is arranged in the base 2, a sealing layer 5 is arranged between the rear end of the base 2 and the housing 1, the housing 1 of the socket is provided with a flange fixing plate, and a flange sealing ring 12 is arranged on the flange fixing plate; the base 2 is provided with 2 pairs of differential assemblies 8 and a plurality of pairs of single-core assemblies, and the differential assemblies 8 are arranged in the middle; and the outer side of the rear end of the plug shell 1 is provided with a grounding ring 3 and a side sealing ring 6. The rear end of the plug shell 1 is connected with a movable tail cover 9, an annular clamping groove 13 is formed in the middle of the tail cover 9, and symmetrical clamping notches 14 are formed in the rear end of the tail cover 9. The connector can be switched on and off by means of a socket and a plug. The sealing layer 5 is glue-pouring sealing, the sealing layer 5 can ensure the airtightness among the shell 1, the base 2 and the lead, and after the socket is connected with the plug, the contact surface can keep the airtightness through the flange sealing ring 12 so as to improve the waterproof performance of the connector. 2 pairs of differential assemblies 8 and a plurality of pairs of single-core assemblies provide the connection requirements of high-speed digital signals and control signals, and the differential assemblies 8 are arranged in the middle and are slightly interfered by the outside.
