Abstract
The utility model relates to a power supply cable connector, concretely to a two-core waterproof connector. The two-core waterproof connector comprises a plug and a socket which respectively possess respective housings, insulating members and internal conductors. The front end of the plug housing is inserted into a splicing aperture of the socket housing; the plug housing is sleeved with a locking screw nut which is axially limited through a circular crossette on the plug housing and is in cooperation connection with outside threads on the socket housing through internal threads on the end portion of the locking screw nut. The root of the crossette orientated to the socket side is provided with a sealing ring slot equipped with a sealing ring; the outer edge of the splicing aperture of the socket housing is provided with a conical surface contacting with the sealing ring. The waterproof effect of the two-core waterproof connector can meet higher use requirements, insulating members with special glass sintering structures are not needed, and manufacturing process is simplified; two pairs of jacks and pins with opposite installation positions are employed to realize conductive connection in the two-core waterproof connector and misoperation of inversed inserting can be avoided.
Description
Technical field
The utility model relates to a kind of feed cable connector, specifically is a kind of two core water-proof connectors.
Background technology
The conventional power source cable connector generally includes plug and socket, and plug and socket has shell, insulating part and inner wire separately respectively.For the higher connector of waterproof requirement, the insulating part that glass sintering forms is set between its inner wire and the shell usually, infiltrate the cable back segment to prevent water; For two core connectors, the anti-misoperation of inserting takes place for comprising that two pairs cooperatively interact and contact pin and jack in its inner wire easily in the installation process.
Summary of the invention
The utility model technical problem to be solved is, provide a kind of simple in structure, be easy to make, peg graft conveniently, two core water-proof connectors of good waterproof performance.
The two core water-proof connectors of the utility model include plug and socket; Plug and socket has shell, insulating part and inner wire separately respectively; The front end of plug body is inserted in the spliced eye of jack housing; Be set with a locking nut on the plug body, locking nut is by the annular convex shoulder axial limiting on the plug body, and locking nut is connected through the internal thread of its end and the external screw thread on the jack housing; Said convex shoulder has seal groove and is mounted with sealing ring towards the root of socket one side, and the spliced eye outer rim of jack housing is provided with the conical surface that can contact with sealing ring.
The inner wire of said plug comprises a jack and a contact pin, and the inner wire of socket comprises a contact pin and jack that adapts with plug simultaneously.
The utility model is realized the inner and outer sealing of connector through the structure that on the plug and socket shell, is provided with, and waterproof effect can satisfy higher instructions for use, need not to use the insulating part of special glass sintering structure, the manufacturing process of simplification; Adopt two pairs of opposite jacks of installation site to realize that with contact pin the conduction of two in-core conductors is connected, can guarantee can not occur instead to insert misoperation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
