Description

Technical Field

[0001] The invention relates to the technical field of high-voltage cable connectors, in particular to a self-locking and repeatedly socket-inserted high-voltage cable connector. Background Art

[0002] A high-voltage cable connector is an electrical connection device used in high-voltage power transmission systems. Its main function is to safely and reliably connect and disconnect high-voltage cables to achieve power transmission and distribution. High-voltage cable connectors are mainly composed of four basic structures: contactors, insulators, plastic shells and accessories. They can be connected at both ends of the cable for mutual plugging. They are usually used in power systems, substations, wind power generation, solar power generation and other fields.

[0003] Reference patent application number CN202220146816.5 is an outdoor high-voltage cable connector. The prior art ensures the fixing effect between the first positioning plate and the second positioning plate by rotating the positioning screw into the threaded groove inside the guide rod when the guide hole of the first positioning plate contacts the guide rod on the surface of the second positioning plate. This can prevent the first circular shell from loosening or falling off from the second circular shell, thereby ensuring the normal use of the cable connector. However, the patent has the following shortcomings:

[0004] When the male head and the female head are connected, they are locked by positioning the screw rod and the thread groove. However, the threaded connection structure has poor stability during use, and it is cumbersome and time-consuming to install them one by one. It is easy to loosen under the swing and vibration of the high-voltage cable for a long time, resulting in disconnection, posing a safety risk. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a self-locking and repetitive socket-type high-voltage cable connector, which solves the problems that the threaded connection structure has poor stability during use, is cumbersome to install one by one, and is prone to loosening and disconnection due to the swing and vibration of the high-voltage cable for a long time.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A self-locking and repetitive socket-insertion high-voltage cable connector, comprising a connector body, the connector body comprising a male head and a female head, and further comprising:

[0007] Two groups of connection components are respectively arranged at the top and bottom of the connector body, and the connection components include a connection plate fixed to the surface of the male head, a plug rod is fixedly connected to the surface of the connection plate, and a fixing plate is fixedly connected to the surface of the female head;

[0008] A locking assembly, arranged inside the fixing plate, for limiting the insertion rod;

[0014] Preferably, the mounting assembly comprises a screw rod fixed on the surface of the rigid sealing ring, and one end of the screw rod passes through the outside of the hollow annular plate and is threadedly connected to a hand nut.

[0015] Preferably, a support frame is fixedly provided inside the male connector, and a pin is provided inside the support frame, a socket adapted to the pin is fixedly connected to one side of the female connector, and cables are provided at the ends of the male connector and the female connector facing away from each other.

[0016] Preferably, a heat dissipation mechanism is provided inside the male head, and the heat dissipation mechanism includes two heat absorbing shells fixed to the inner wall of the male head, a plurality of heat conducting plates are fixedly connected to the inner wall of the male head, and one side of the heat conducting plate is connected to the surface of the heat absorbing shell, an inner cavity is provided inside the heat absorbing shell, a plurality of heat dissipation rods are fixedly connected to the surface of the heat absorbing shell, and a heat dissipation channel connected to the inner cavity is provided inside the heat dissipation rods.

[0020] (2) The self-locking and repetitive socket-type high-voltage cable connector has an elastic sealing ring that enters the sealing groove when the male head and the female head are connected to seal the connection, thereby improving the waterproof effect. At the same time, the sealing component can compensate for the elastic force lost by the elastic sealing ring under the action of the elastic component, thereby extending the service life of the sealing component and improving the sealing performance.

[0021] (3) The self-locking and repetitive socket-type high-voltage cable connector has a connector body that conducts internal heat to a heat-absorbing shell through a heat-conducting plate. The heat enters the heat-absorbing shell and is conducted out of the connector through a heat dissipation channel of a heat dissipation rod, thereby dissipating heat inside the connector and improving the high-temperature resistance of the high-voltage cable connector.
