Photoelectric composite underwater plug connector

Abstract

The invention relates to a photoelectric underwater plugging connector. A plug is composed of an outer shell, a plug housing, a plug core, a first lip-shaped sealing element, an electrical contact pin A, a fiber plugging core B, a first adapter base and a first tail connecting element. A socket consists of a second tail connecting element, a second adapter base, a socket housing, a socket core, a socket sliding block, a second lip-shaped sealing element, an electrical contact pin C and a fiber plugging core D. When extending out of the inner cavity of the plug housing slightly, the left end of the first lip-shaped sealing element is closed and sealed; when retracting into the inner cavity of the plug housing, the left end of the first lip-shaped sealing element opens; when extending into the inner cavity of the socket sliding block, the right end of the second lip-shaped sealing element is closed and sealed; and when the socket sliding block separates from the right end of the second lip-shaped sealing element, the right end of the second lip-shaped sealing element opens and the outer shell and the socket housing are buckled and connected. Therefore, the operation is simple; underwater plugging is realized; the workload is reduced substantially; and underwater equipment can be repaired or replaced conveniently.

Description

technical field [0001] The invention relates to the field of underwater detection, in particular to a photoelectric composite underwater plug-in connector for underwater signal transmission. Background technique [0002] Due to the needs of the military and the further exploration and development of marine resources, photoelectric composite underwater plug connectors, as an indispensable and important part of underwater systems, are increasingly used underwater. At present, underwater plug-in connectors are widely used in underwater large-scale engineering projects such as underwater detection arrays, port acoustic-magnetic monitoring, and underwater weapon trajectory. The use of photoelectric composite underwater plug-in connectors facilitates these engineering projects Network interconnection between base stations and detection nodes in different areas and between these base stations, detection nodes and control terminals is established.

Problems solved by technology

[0003] Conventional photoelectric composite underwater plug-in connectors generally include plugs and sockets. The transmission of photoelectric information is realized through the insertion of plugs and sockets. The operation is relatively simple. However, due to the constraints of current sealing technology, the existing underwater photoelectric composite connections The connector can only be docked with the plug and socket on the land bank or on the water surface, and then put it into the water as a whole to work, and it cannot be plugged and unplugged underwater. This is very difficult for system laying, because the plugged connector needs to be Putting the entire system into the water requires a considerable amount of work and high laying costs. In addition, when repairing or replacing other underwater equipment, the entire system needs to be pulled out again, which is very inconvenient
