A live pluggable underwater wet electrical connector

Abstract

The invention relates to a live pluggable underwater wet electrical connector, which comprises a male plug body and a female socket body. The top of the male plug is provided with a first-level locking groove, which is nested with a slidable pin assembly and an attached second-level locking groove, and a non-slidable second-level locking claw; the female socket is equipped with a male A primary locking claw and jack assembly that matches the plug. When mating, the two-stage locking mechanism cooperates and the pins and sockets cooperate to make the electrical connector sealed and locked; when pulling out, the secondary locking structure separates before the primary locking structure. The conductive inner core of the pin is always in a sealed and insulated environment during the entire insertion and extraction process, which can realize underwater live insertion and extraction. The invention has a double oil-filled pressure balance structure, can adapt to different deep water pressures, and can improve the service life; the connection method is direct and fast, the insulation and sealing performance is good, and accidental detachment can be effectively prevented. After matching the present invention, work such as assembly, connection, disassembly and replacement of underwater electrical equipment can be carried out economically and efficiently.

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
