Rapid wet plugging electric connection structure

Abstract

The invention discloses a rapid wet plugging electric connection structure, which comprises a base, a cover shell is plugged to the top of the base, a magnetic induction switch is fixedly connected to the top of the cover shell, an insertion rod is plugged into the base, a fixing block sleeves the bottom of the insertion rod, two rapid dismounting head mounting seats are arranged on the inner bottom wall of the base, and a magnetic induction switch is fixedly connected to the bottom of the rapid dismounting head mounting seats. And a quick-release head female head and a quick-release head male head are respectively inserted into the two quick-release head mounting seats. The invention relates to the technical field of underwater electric connection and quick wet plugging. According to the quick wet-plugging electric connection structure, the second pin is inserted to push the O-shaped ring, water in the quick-release female head can be discharged through the drainage groove to release pressure, the quick-release male head is continuously pushed, the O-shaped ring wraps the drainage groove to realize sealing, pressure is generated in the sealing cavity, the quick-release male head is continuously pushed at the moment, the internal pressure is increased, and the quick-release male head is inserted into the sealing cavity. The O-shaped ring is pushed in the sealing pressure relief groove due to the internal pressure, the internal pressure is balanced, and therefore the effect of rapid insertion connection is achieved.

Description

technical field [0001] The invention relates to the technical field of underwater electrical connection and fast wet plugging, in particular to a fast wet plugging electrical connection structure. Background technique [0002] Underwater electrical connection technology is widely used in various underwater equipment. In actual use, many underwater equipment have the need to realize fast plugging and unplugging of electrical connections underwater, such as: quick battery replacement, replacement of various functional modules, etc. . [0003] When the existing quick wet plug electrical connection structure is in use, all contact pins are designed in the same sealed cavity, and plugging and unplugging underwater will cause internal water ingress, electrolysis or short circuit of the contact pins, which cannot meet the needs of underwater plugging and unplugging. Demand, although the connector with end face seal can realize underwater plugging, but when pulling out, if the exte...

Problems solved by technology

[0003] When the existing quick wet plug electrical connection structure is in use, all contact pins are designed in the same sealed cavity, and plugging and unplugging underwater will cause internal water ingress, electrolysis or short circuit of the contact pins, which cannot meet the needs of underwater plugging and unplugging. Demand, although the connector with end face seal can realize underwater plugging, but when pulling out, if the external water pressure is too large, it will be difficult to pull out. It is designed for active power-off situations, power-on and power-off operations and plug-in operations There is no logical relationship, so it is very easy to misuse, resulting in live plugging and unplugging, resulting in electrolysis of connectors and even equipment damage
