Underwater wet-type electric connector capable of being plugged and unplugged in electrified mode

Abstract

The invention relates to an underwater wet-type electric connector capable of being plugged and unplugged in an electrified mode. The underwater wet-type electric connector comprises a male plug bodyand a female socket body, wherein the top end of the male plug is provided with a first-stage locking groove, and a slidable pin assembly, an attached second-stage locking groove and a non-slidable second-stage locking claw are nested in the male plug; and the female socket is internally provided with a first-stage locking claw and a jack assembly which are matched with the male plug. During plugging, the two stages of locking mechanisms are matched with each other, and contact pins are matched with the jacks, so that the electric connector is sealed and locked; and during pull-out, the second-stage locking structure is separated before the first-stage locking structure. In the whole plugging process, a conductive inner core of the contact pin is always in a sealed insulating environment,and underwater hot plugging can be realized. The electric connector has a dual-oil-charging pressure balance structure, can adapt to different deep water pressures, and can prolong the service life; and the connection mode is direct and fast, the insulation sealing performance is good, and accidental disengagement can be effectively prevented. After being matched with the electric connector, underwater electric equipment can be economically and efficiently assembled, connected, disassembled, replaced and the like.

Description

technical field [0001] The invention relates to the technical field of pluggable electrical connectors, in particular to a live pluggable underwater wet electrical connector. Background technique [0002] At present, the relatively popular marine research fields, such as deep-sea oil and gas resource development, deep-sea exploration and scientific research, and underwater weapon platforms, have a large number of underwater electrical equipment, which need to be connected to sea surface carriers or shore-based facilities through cables to form an electrification circuit. Only in order to work underwater for a long time, the connection between cables and electrical equipment is inseparable from electrical connectors, and traditional electrical connectors are divided into waterproof and non-waterproof. The working principle of the common waterproof electrical connector is: place it underwater after being plugged tightly on the water surface, and isolate the internal electrical...

AI Technical Summary

Problems solved by technology

However, the existing underwater wet connectors still cannot realize live plugging and unplugging. The reason is that the male plug with pins is exposed to seawater after being pulled out from the female socket, and the mutual insulation between the core circuits fails.

Once this type of electrical connector is passively separated due to the interference of external accidental loads, the circuits of each pin will be short-circuited in sea water, which may cause burning of the cable line, resulting in reduced production and shutdown of equipment, and severe electric shock accidents on the power supply on the water surface , and even cause a fire
