Technical field
It the utility model is related to a kind of underwater optical fibre snap joint, the fast quick access of optical fiber between particularly a kind of underwater installation
Head.
Background technology
Underwater optical fibre snap joint is that one kind is used for subsurface communication Transmission system, is widely used in underwater robot ROV.Water
When lower robot works in water, water surface unit realizes the manipulation to robot by fiber optic communication, and robot is in Shui Zhongguan
The environment examined and under water depth highly etc. feed back to water surface one side by optical fiber transmission, realize human-computer exchange.Optical fiber
Transmission has bandwidth, and message capacity is big, loss is low, and repeater span is long, anti-electromagnetic interference capability is strong, without cross-talk, secrecy
Property is good, line footpath is thin, series of advantages, the application field such as in light weight, soft are more and more extensive.
Optical fiber is used to first have to solve the problems, such as to be how the sealing problem for carrying out optical fiber under water, it is ensured that underwater circuit
System is safe and reliable.The underwater optical fibre joint that uses both at home and abroad is mainly the armored fiber optic wire jumper through over cure at present, cost into
This costliness, order cycle time length, joint installing space is big, influences ROV integral layout.
Utility model content
The purpose of this utility model is, there is provided a kind of underwater optical fibre snap joint.The utility model is compact-sized, sealing
Reliably, make connection and signal transmission between optical fiber more convenient.
The technical solution of the utility model：A kind of underwater optical fibre snap joint, including pin end and female joint；The public access
Head is provided with the first externally threaded erection joint including rear end；The female joint includes set core, and the rear end for covering core is connected by anchor ear
There is flexible pipe；The leading inside of set core is provided with fiber coupler, and the front end outer side for covering core is provided with attaching nut；Erection joint front end is set
There is the second external screw thread being engaged with attaching nut.
In foregoing underwater optical fibre snap joint, the first externally threaded bottom of the erection joint is provided with the first sealing
Circle.
In foregoing underwater optical fibre snap joint, the set core front end outer side is provided with the second sealing ring.
In foregoing underwater optical fibre snap joint, second external screw thread is trapezoidal thread.
In foregoing underwater optical fibre snap joint, the fiber coupler is FC circular flange couplers.
Compared with prior art, the utility model cost is relatively low, compact-sized, reduces joint installing space；This practicality
It is new to be provided with multi-sealing structure, safe and reliable, convenient disassembly, make connection and signal transmission between optical fiber more convenient.
