Underwater anti-short circuit separate electric connector

Abstract

The electric connector is composed of socket and plug. Wire out port of the socket is connected to back shell body of the socket, and unlocking sheath is connected to releasing gear. The unlocking sheath via sidestep pulls movement of front shell body of the socket. Connecting rod connected to insulator module in middle of socket is setup on the unlocking sheath. Through the connecting rod, the unlocking sheath drives axial motion of the insulator to turn signal inside the socket on / off. After unlocking, through water inlet troughs on plug and socket, water enters into insertion face of the connector in order to realize balance between inner and outer hydraulic pressures. The plug with two jacks is installed in insulator module. One end of the plug is always contacted to connector pins, and the other end is assorted to connector pins to implement turning electric signal on / off. With simple structure, the invented electric connector prevents short circuit reliably.

Description

technical field [0001] The invention relates to an underwater anti-short-circuit separation electrical connector, which can realize separation in deep water environment, and the socket can reliably prevent short-circuit during and after separation of products, that is, after the mating surface of the socket is short-circuited by water, the back of the socket (cable parts) contacts will not short circuit, and can be used in various underwater cable networks to play the role of electrical signal connection and separation. Background technique [0002] Foreign underwater anti-short-circuit separation electrical connectors, such as the 8810-76H series products produced by the French SOURIAU company, have a cable-type separation method. This type of electrical connector does not have a hydraulic pressure balance mechanism, and the underwater separation force is relatively large (underwater 300m when >1700N). Moreover, the product does not have an anti-short-circuit mechanism....

AI Technical Summary

Problems solved by technology

[0002] Foreign underwater anti-short-circuit separation electrical connectors, such as the 8810-76H series products produced by the French SOURIAU company, have a cable-type separation method. This type of electrical connector does not have a water pressure balance mechanism, and the underwater separation force is relatively large (underwater 300m When >1700N)

Moreover, the product does not have an anti-short-circuit mechanism. After the head seat is separated, the contacts of the socket wiring part are short-circuited, so the product must be separated when the power is off.

[0003] There are domestic underwater anti-short-circuit separation electrical connectors, such as: YSF1 products, the separation method is a pull-rod mechanical separation, and the water pressure balance method is to store oil in the connection mechanism to achieve balance. The balanced water pressure effect is better, but the oil storage The operation is cumbersome, it takes several hours to store oil at a time, the efficiency is low, and the maximum separation depth can only reach 100m underwater

Although the product socket also has an anti-short-circuit structure, its structure is complex. The mating surface is sealed by potting and cannot be disassembled. Therefore, the anti-short circuit mechanism is not maintainable. Once a problem occurs, the socket must be replaced.
