Described block is " 7 " the font block that is formed on gland both sides, and step trough is formed at the top of described gland, and described step trough matches with " 7 " font block.The block of this structure can not only promote the bulk strength of gland, also can improve the stability that gland and base coordinate.
" U " shape groove is formed at the bottom of described V-shaped groove base, should arranging of " U " shape groove can clamp the optical fiber of imbedding, and prevents that it is offset, and guarantees the reliability that optical fiber connects.
Described V-shaped groove assembly and fiber fixed seat, oversheath are integrated assembling, on V-shaped groove assembly, be equipped with the snap close sliding before and after an energy, the rear portion of described snap close arranges linked switch, and described tail cover is linked with snap close, during assembling tail cover, tail cover interlock snap close reach locking fiber alignment.On snap close, increased fiber alignment linked switch, after optical fiber penetrates, in tail cover locking optical cable, the anchor switch that links completes V-type groove inner fiber and optical fiber in being embedded in ceramic body to dock.
The main body of described snap close is annular solid, and the rear portion of described annular solid arranges the linked switch of the automatic butt optical fiber that extends annular solid, on described linked switch, forms draw-in groove.Tail puts and forms fixture block or the projection that draw-in groove matches, when locking tail when cover screw-home movement fiber alignment step of having taken advantage of a situation that links
Described tail cover is M6 nut, and the rear portion of described fiber fixed seat forms the insertion piece matching with nut, and the inner of described insertion piece forms zigzag fixture block.Greatly dwindled small product size,
Described tail cover is square tail cover, and the unidirectional elasticity in formation both sides, rear portion of described fiber fixed seat is inserted piece, and the outside portion that described elasticity is inserted piece forms fixture block, described fixture block and square tail cover snapping.
The front portion of described fiber fixed seat arranges elastic bayonet lock, the unidirectional clamping bronze gong of described elastic bayonet lock cap.
The utlity model has following advantage:
1.V type groove both sides are designed with continuous baffle plate, and the intensity that has not only increased V-type groove prevents distortion, and V-type bowl assembly precision-fit prevents from mating cream loss, this structure not only makes device work more stable, can also greatly extend the serviceable life of device.
2. existing quick coupler often needs to use a lot of auxiliary small tools, has also needed tightening nuts, lock fiber switch, more a plurality of steps such as oversheath has been installed and carries out joint connection in site.The utility model integrated design product and V-type groove fiber alignment automatic switch, single stepping can be realized optical fiber and reliably dock, and has solved the defect that former such devices needs a plurality of steps assemblings, has greatly improved installation effectiveness, reduces assembling difficulty.
3. existing FC product needed has a lot of parts to spell system, the utility model FC type Realization of Product integrated design, and flexible bayonet socket one direction blocks and connects bronze gong cap, prevents screw cap-falling.
4. the tail end of fiber fixed seat adopts M6 nut to reduce small product size or the outer cable of plug-in type tail cover fixed fiber, easy to operate, fixing reliable.
