Description
Technical field
The invention belongs to electrical connector technical fields, and in particular to a kind of multi-functional optical fiber quick connector.
Background technology
Optical fiber is writing a Chinese character in simplified form for optical fiber, is a kind of fiber made of glass or plastics, can be used as light conduction tool.It passes
Defeated principle is the total reflection of light.Fine optical fiber is encapsulated in plastic sheath so that it can be bent and be unlikely to be broken.It is logical
Often, light pulse is sent to optical fiber by the emitter of one end of optical fiber using light emitting diode or beam of laser, optical fiber it is another
The reception device at end detects pulse using light-sensitive element.Optical fiber connector is that detachable (activity) is carried out between optical fiber and optical fiber
The device of connection, it gets up two end face precision docking of optical fiber, so that the light energy of launching fiber output can be to greatest extent
Ground is coupled in reception optical fiber, and makes to influence to minimize caused by system since it intervenes optical link, this is optical fiber
The basic demand of connector.Optical fiber connector can be divided into the single mode of common silica-based optical fibers by the difference of transmission medium and multimode connects
Device is connect, it is also other such as using plastic cement as the optical fiber connector of transmission medium；It can be divided by connector structure type：FC、SC、
ST, LC, D4, DIN, MU, MT etc. various forms.Wherein, ST connectors be commonly used in wiring unit end, as fibre distribution frame,
Optic module etc.；And SC and MT connectors are commonly used in network equipment end.By fiber end face shape point have FC, PC (including SPC or
) and APC UPC；Point for also having single and multicore (such as MT-RJ) is divided by fiber number.Optical fiber connector is widely used, and kind is numerous
More, in actual application, we are distinguish generally according to the difference of fibre-optic connector structure.To a certain extent,
Optical fiber connector affects the reliability and properties of optical transmission system.
Existing optical fiber connector is complicated for operation when connecting two optical fiber, effectively optical fiber cannot be fixed, separately
When two fiber end faces of external docking, the interval between fiber end face cannot be reduced, it is difficult to ensure quality of connection and optical signal coupling
Close stability.
