An underwater electromagnetic shedding connector

Abstract

An underwater electromagnetic shedding connector, including a plug assembly, a socket assembly and an outer protection assembly, the plug assembly includes a plug outer tube, a first ejection mechanism and a locking mechanism, the first ejection mechanism, the lock The tightening mechanisms are all arranged inside the outer tube of the plug, and the locking mechanism is arranged at the center line of the outer tube of the plug; the socket assembly includes an electromagnetic unlocking mechanism arranged coaxially, an outer tube of the socket, a tail cover, and a coil Outer jacket and locking sleeve, the outer protection assembly includes a connection cover, a protective cover, a second ejection mechanism and a screw sleeve; the electromagnetic connector of the present invention can be normally disengaged in deep water, the coil will not be exposed to seawater, and the coil can Use repeatedly.

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] Although some connectors can solve the corrosion problem at sea, so that the connector can be used at sea, there are still the following defects: it is only suitable for the environment above the sea surface, and when used in deep water areas, the external seawater pressure is much higher than that of the socket and the outer protection components The separation force, the connector can only complete the separation of the socket and the plug once driven by the electromagnetic force, and then the seawater will squeeze the socket inward, the socket and the shell cannot be separated, and 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, and the maintenance cost is high.
