Underwater electromagnetic shedding connector

Abstract

An underwater electromagnetic drop connector comprises a plug assembly, a socket assembly and an outer protection assembly; the plug assembly comprises a plug outer tube, a first ejection mechanism and a locking mechanism; the first ejection mechanism and the locking mechanism are both arranged in the plug outer tube, and the locking mechanism is arranged at the center line of the plug outer tube;the socket assembly comprises an electromagnetic unlocking mechanism, a socket outer tube, a tail cover, a coil outer sleeve and a locking sleeve which are coaxially arranged. The outer protection assembly comprises a connecting cover, a protection cover, a second ejection mechanism and a threaded sleeve. The electromagnetic connector can be normally separated in deep water, the coil cannot be exposed in seawater, and the coil can be repeatedly used.

Description

technical field [0001] The invention belongs to the technical field of communication connectors, in particular to an underwater electromagnetic shedding connector. Background technique [0002] With the development of the national marine strategy, more and more weapons and equipment need to be dragged underwater. Signals are transmitted between the weapons and the parent body through shedding connectors and composite cables. When an emergency occurs underwater, it needs to be disconnected. The connection between the two protects the rapid evacuation of the mother body. At present, most of the connectors with underwater release function use strong mechanical pull-off, which requires external connection to provide a large mechanical pull. The operation steps are cumbersome and the response speed is slow. There is an urgent need for underwater electromagnetic release connectors that can be remotely controlled.

Problems solved by technology

At present, most of the connectors with underwater release function use strong mechanical pull-off, which requires external connection to provide a large mechanical pull. The operation steps are cumbersome and the response speed is slow. There is an urgent need for underwater electromagnetic drop-off connectors that can be remotely controlled.

[0003] Publication number: CN110086036A's invention patent "a new type of double-layer sealed electromagnetic shedding connector" can solve the corrosion problem at sea and enable the connector to be used at sea, but it still has the following defects: it is only suitable for the environment above the sea surface. When used in deep water areas, the external seawater pressure is much higher than the separation force between the socket and the outer protection component. The connector can only complete the separation of the socket and the plug once driven by electromagnetic force, and then the seawater will squeeze the socket inward, and the socket and the shell cannot be separated. Separated, the electromagnetic shedding function cannot be realized in a deep water environment; after the connector is separated, the electromagnetic coil is placed in the protective cover. Since the protective cover is installed outside the transmitter, the electromagnetic coil will be damaged due to long-term exposure to seawater. Maintenance high cost
