The connector of claim 9, wherein: the shell part is the screw thread shell part, and the screw thread shell part is including interior casing subassembly and shell body subassembly, and interior casing subassembly is located in the shell body subassembly, and interior core part is installed in interior casing subassembly, and the shell body subassembly is arranged in realizing headstock locking with adaptation connector casing threaded connection, interior casing subassembly is including the front end inner shell and the tail end seal structure that are connected.

13. The connector of claim 12, wherein: the inner wall of the outer shell assembly is provided with an inverted hanging structure along the circumferential direction, and the outer wall of the inner shell component is provided with an adaptive inverted hanging structure which is in blocking fit with the inverted hanging structure along the axial direction.

14. The connector of claim 12, wherein: the tail end sealing structure comprises a connecting cap connected with the front end inner shell, the rear end of the connecting cap is a cavity formed by a plurality of circumferentially distributed elastic claws, an elastic rubber ring for a cable to pass through is arranged in the cavity,

after the connector and the adaptive connector are plugged and locked, the tail end conical surface in the outer shell assembly extrudes the elastic claw, and the elastic claw extrudes the elastic rubber ring, so that the inner cavity of the elastic rubber ring is reduced and the cable is extruded to realize sealing protection.

15. The connector of claim 14, wherein: and a stop surface matched with the tail end sealing structure in an axial stop manner is arranged in the tail end of the outer shell assembly to prevent the inner shell assembly from being separated from the tail end of the outer shell assembly.

16. The connector of claim 12, wherein: and a tensile surface is arranged in the inner shell assembly, and the tensile surface is matched with the axial stop at the rear end of the support sleeve to realize the tensile protection of the inserting core component.

17. The connector of claim 12, wherein: the tail of the outer shell component is provided with a protective spring sleeved outside the cable, so that the bending resistance of the cable is improved.

18. Connector assembly, including plug-in connection's connector and adaptation connector, the connector includes the casing part and installs the interior core part in the casing part, its characterized in that: the core component is as claimed in any one of claims 1-8.

19. The connector assembly of claim 18, wherein: the shell component and the adaptive connector shell realize radial rotation stopping after opposite insertion through the headstock rotation preventing structure.
