Description

Deepwater connector Technical Field The utility model belongs to the technical field of connectors, and relates to a deepwater connector. Background Underwater electrical equipment and devices are also widely used when mining resources in deep sea. And the equipment and the device are reliably connected through the deepwater connector to ensure stable electric transportation. Among them, the deep water connector is required to have extremely high water pressure resistance and water resistance. The existing deepwater connector has the defects of poor water tightness, insufficient durability and short service life, and can cause economic loss and reduce the overall resource exploitation efficiency. Disclosure of utility model The utility model aims to provide a deepwater connector and aims to solve the problems of poor sealing effect and short service life of the connector in the prior art. In order to achieve the purpose, the deep water connector comprises a plug and a socket, wherein the socket comprises a socket shell and a conductive structure positioned in the socket shell, the plug comprises a connecting portion, a main body portion and a sealing portion, the connecting portion comprises a first connecting portion and a second connecting portion, the first connecting portion is cylindrical, a pin assembly is arranged in the second connecting portion and is nested in the first connecting portion, one end of the main body portion stretches into and is nested between the first connecting portion and the second connecting portion, the outer surfaces of the main body portion and the second connecting portion are in threaded connection, the sealing portion is arranged at the other end of the main body portion, when the plug is matched with the socket, the second connecting portion is inserted into and abuts against the inner surface of the socket shell, the first connecting portion is in threaded connection with the outer surface of the socket shell, the pin assembly is electrically connected with the conductive structure, and sealing glue is filled in the inner portion of the socket shell and the main body portion. Further, a first sealing ring is arranged on the outer surface of the socket shell, and a second sealing ring is arranged between the second connecting part and the socket shell. Further, the number of the second sealing rings is two. Further, the deepwater connector further comprises a tail cap, and the tail cap is sleeved on the periphery of one end, far away from the connecting part, of the main body part in a threaded connection mode. Further, a third sealing ring is arranged between the tail cap and the main body part. Further, the plug housing, the connecting portion, the main body portion and the tail cap are made of TC4 titanium alloy. Further, the pin assembly comprises a plurality of groups of pins and insulating rubber cores arranged around the pins, and the conductive structure comprises a plurality of groups of conductive columns with jacks and insulating rubber cores arranged around the conductive columns. Further, a glue wrapping layer is further arranged at one end, far away from the connecting portion, of the main body portion. The utility model has the beneficial effects that by arranging the sealing part, the sealant and the sealing ring, the gap between each component of the connector and external connecting equipment is reduced, and the water tightness and the reliability are increased.
