Abstract

The invention relates to an underwater wet plugging pressure balance electrical connector, which belongs to the technical field of underwater electrical connection. It includes a socket main body and a plug main body; the socket main body includes a socket housing and an electrical connection module sealed and arranged in the socket housing; the electrical connection module is provided with a dynamic sealing stop piston, and the stop piston passes through the socket housing; the socket housing is provided with an oil The electrical connection module is arranged in the oil chamber, and the oil chamber is also provided with a first balance soft bag communicating with the outside world; the plug body includes a plug housing and a plug disposed in the cavity of the plug housing. pin, when electrically connected, the plug shell is socketed with the socket shell, and the pin pushes the stop piston and inserts it into the corresponding electrical connection module. The liquid-filled pressure balance design is adopted to minimize or even eliminate the internal and external pressure difference of the underwater connector, improve the compression resistance, and reduce the plug-in force required for wet plug-in. The stop piston can ensure the dynamic sealing performance required for underwater wet insertion, and balance the pressure of seawater through the first balance soft bag.

Description

technical field [0001] The invention relates to the technical field of underwater electrical connection, in particular to an underwater wet-plugging and plugging pressure-balanced electrical connector. Background technique [0002] According to statistics, the vast majority of failure cases in the offshore engineering field are caused by connector failure. There are three main technical difficulties in underwater wet plugging connectors: first, it is necessary to maintain sealing and insulation performance during the dynamic process of plugging and unplugging; second, it is possible to reduce or even eliminate the internal and external pressure difference of the underwater connector so that Adapt to changes in the external pressure environment, improve the ability to resist deep sea pressure, and reduce the insertion force; third, it is difficult to fill the interior with liquid. [0003] The patent application document with publication number CN107910699A discloses a press...
