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 3 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 watertight electrical connector in the marine field, which provides an oil-filled jack that can be plugged and unplugged under water, and includes a plug and a socket that cooperate with each other. The plug includes an outer shell and an inner shell, and the inner shell includes an elastic connector. The outer wall and the rigid inner tank are equipped with several independent cylindrical socket components inside the oil chamber. When the plug of the present invention enters the water, exits the water or is inserted and pulled out underwater, the deformation of the pressure balance film of the oil-filled chamber of the plug can adjust the pressure balance inside and outside the oil-filled chamber, so that there is no pressure gradient inside and outside the oil chamber, realizing deep-sea sealing and underwater plugging and unplugging , The connection and disconnection of pins and sockets are all carried out in insulating oil, which can effectively annihilate the arc generated during connection and separation, and realize live plugging and unplugging.

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...
