specific Embodiment 2

[0080] Specific embodiment 2 of the connector assembly of the present application: The difference between this embodiment and embodiment 1 is that the limit structure is different. Stop fit, outer side and varus edge stop fit. As another example, the circumferential blocking protrusion may be a single protrusion or a plurality of protrusions distributed at intervals along the circumferential direction.

specific Embodiment 3

[0081] Specific embodiment 3 of the connector assembly of the present application: The difference between this embodiment and embodiment 1 is that no sealing ring is provided, and the cooperation between the circumferential stopper protrusion and the inversion edge is used to avoid impurities from the inversion edge and the inversion edge. The gaps between the circumferential stop protrusions enter the inner cavity of the protective sleeve connector.

specific Embodiment 4

[0082] Embodiment 4 of the connector assembly of the present application: The difference between this embodiment and Embodiment 1 is that the sealing ring receiving groove is arranged on the inversion edge, and the sealing ring can be prevented from coming out by means of gluing or the like. For another example, the sealing ring can be replaced by an annular sealing gasket (with a rectangular cross-section), and at this time, the sealing ring receiving groove may not be provided. As another example, the sealing ring can be replaced by sealing packing.

Abstract

The invention relates to a connector assembly and a plug. The plug is used for a double-sheath cable. The connector assembly comprises a cable connector and a protective sleeve connector. The cable connector comprises a first locking cap, and the first locking cap is used for being connected with a first external thread on a corresponding socket; and the protective sleeve connector comprises a tail housing which is used for being fixedly connected with a protective sleeve of the double-sheath cable. A second locking cap is used for being connected with a second external thread on the socket; the second locking cap can move backwards relative to the tail housing; and a limiting structure is arranged between the second locking cap and the tail housing and used for preventing the second locking cap from being separated from the tail housing forwards. In use, the second locking cap is moved backwards relative to the tail housing so as to expose the first locking cap of the cable connector,and then, the second locking cap is moved forwards to make the second locking cap reach the connecting place. According to the plug provided by the invention, different lengths of cables with sheathsand protective sleeves do not need to be arranged, so that the assembly difficulty of the plug and the double-sheath cable can be reduced, and the tearing of the protective sleeve can be avoided.

Description

technical field [0001] The invention relates to a connector assembly and a plug. Background technique [0002] When the external environment is relatively harsh, a double-layer connection connector assembly is usually used. The inner layer connection in the double-layer connection realizes signal transmission, and the outer layer connection protects the inner layer connection from the erosion of external sand, stone and rain. [0003] The balise transmission unit (BTM) of the common train control on-board equipment includes the on-board BTM module, the balise antenna and the ground balise, and the three form a point communication system. The feeder connection between the vehicle-mounted BTM module and the transponder antenna uses the connector assembly of the above-mentioned double-layer connection form, specifically: the BTM feeder is a double-sheathed cable, including a sheathed cable 205 and a surrounding set on a sheathed A protective sheath 206 outside the cable 205 , ...
