Problems solved by technology

Due to the pressure of seawater, it is very difficult to separate the connectors. Even if the separation is under the pressure of seawater, the seawater must enter the cavity after the separation of the connectors, causing leakage and electrode corrosion under electrochemical action. At present, it is specially used in seawater. All connectors are required to be connected on land and then used in seawater, but under some specific conditions, there is a need to plug and unplug connectors underwater

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] The present invention provides an oil-filled jack that can be plugged and unplugged underwater. The jack is installed inside the plug, such as figure 1 As shown, the plug structure includes an outer shell and an inner shell 1. The outer shell is used to fix and connect with the socket shell. Since the shape of the outer shell can be matched according to actual needs, a common connector shell on the market can be selected, so it is no longer required. repeat.

[0025] The inner casing 1 is provided with an outer wall of elastic material and a rigid inner tank 3, and the inner tank 2 is provided with a number of pressure balance holes for adjusting internal and external pressure, and the outer wall of the pressure balance hole is covered. In this embodiment, the inner tank is divided into front and rear parts, the inner tank 3 is cylindrical, the front and rear p...

Abstract

The invention relates to a water-tight electric connector for an ocean field, and provides an oil-charging jack capable of hot plugging under water. The oil-charging jack comprises a plug and a socket which are matched mutually; the plug comprises an outer shell and an inner shell; the inner shell comprises an elastic outer wall and a rigid inner container; a plurality of independent cylindrical jack components are arranged in an oil cavity. When the jack is plugged into water, out of water or under water, by the deformation of a plug oil-charging cavity pressure balance membrane, balance of pressures inside and outside an oil-charging cavity is regulated, so that a pressure gradient does not exist inside and outside the oil cavity, deep sea sealing and plugging under water are realized, switching on and switching off of a contact pin and the jack are carried out in insulating oil, an electric arc generated during switching on and separating can be effectively annihilated, and hot plugging is realized.

Description

technical field [0001] The invention relates to a watertight electrical connector in the marine field, in particular to an oil-filled jack that can be plugged and unplugged underwater. Background technique [0002] Ordinary electrical connectors cannot be immersed in water, because usually water contains electrolytes and can conduct electricity, especially seawater has better conductivity, and can short-circuit conductors immersed in water. At present, there are dry plug / underwater connectors and wet plug / underwater connectors in the domestic market. These two connectors cannot be plugged and unplugged in deep water. Due to the pressure of seawater, it is very difficult to separate the connectors. Even if the separation is under the pressure of seawater, the seawater must enter the cavity after the separation of the connectors, causing leakage and electrode corrosion under electrochemical action. At present, it is specially used in seawater. All connectors are required to b...
