The whole displacement SC type hot melting field assembly connector adopts the whole moving design concept and fully considers that in actual use of the connector, bare fibers cannot bend by using the heat shrinkable tube with double reinforced ribs in a certain space, so that the connector is more stable in performance and is greatly enhanced in reliability.
Description
Technical field
The utility model belongs to communication network device technical field optical fiber and uses apparatus field, the joints of optical fibre that especially a kind of field by using thermal welding mode continues.
Background technology
At present, the field splicing connector that uses on the market is the mechanical splice connector mostly, and the connector of producing the hot melt continuation method is seldom arranged.There are defectives such as unstable properties, the life-span is short, the field splicing success ratio is low at the mechanical splice connector that uses now; Now on the market at the connector of the external hot melt continuation method of usefulness because the design problem in the mechanism; Make connector spring cisco unity malfunction; And the bare fibre of rear portion welding is in stressed case of bending always during connector work; It is too big, unstable to insert loss, and is easy to disconnected fibre, makes its performance, life-span all can't satisfy relevant country and industry standard.
The employing of the traditional hot draw that uses in the fibre junction at present be the mode of single reinforcement, be out of shape together on one side single reinforcement causes heat-shrink tube when reinforcement is out of shape, to drive optical fiber when pyrocondensation easily, make the fibre-optical bending decay become big, even disconnected fine.
Summary of the invention
For solving the problems of the technologies described above; Improve easily broken fibre in the fibre junction, performance, life-span can't be satisfied problems such as GB, and the utility model is pressed into one with the tail optical fiber in ceramic insertion core and the rear portion welding pyrocondensation rod; Common advance and retreat; And spring is external, make when spring can operate as normal optical cable, weld and the ceramic core retraction that advances jointly.The utility model adopts technical scheme following:
Comprise shell 1, retaining ring spare 10 is connected with white straight cover 8 buckles in shell 1 inside, and spring 9 and the ceramic core print seats 11 in spring 9 inside are positioned at retaining ring spare 10; Pottery core print seat 11 can be movable in internal taping spare 10, and ceramic core print seat 11 and ceramic core 7 consolidations also comprise connector 2; Heat-shrink tube 3, tailstock 4, tailstock 4 tail ends are provided with to be renovated; When renovating closure and tailstock 4 constitute complete external thread, also comprise a nut 5 that the internal thread that cooperates with external thread is arranged.Heat-shrink tube 3 has 2 reinforcements, lays respectively at heat-shrink tube 3 left and right sides.
Aramid fiber in the optical cable is wrapped on the external thread, and is tightened by the internal thread of nut 5.
The utility model heat-shrink tube has been abandoned the mode of single reinforcement of the traditional hot draw; Use two reinforcements, because use behind two reinforcements after the heat-shrink tube pyrocondensation, bare fibre is positioned at dummy section in the middle of two reinforcements; And certain space is arranged; Bare fibre just can never be crooked like this, makes connector performance more stable, and reliability strengthens greatly.And solved the present use external product spring situation unstable, easily broken fibre of can't working, decay, dependable performance is stable, can do to be used for FTTX and communication machine room on a large scale.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the embodiment of the invention is done further detailed explanation.
The present technique scheme comprises shell 1, and shell 1 inner interior retaining ring spare 10 is connected more existing connector with white straight cover 8 buckles; This programme has strengthened spring 9, and spring 9 and the ceramic core print seats 11 in spring 9 inside are positioned at retaining ring spare 10, and ceramic core print seat 11 can be movable in internal taping spare 10; Pottery core print seat 11 and ceramic core 7 consolidations, ceramic core 7 can operate as normal like this, also comprises connector 2; Heat-shrink tube 3, tailstock 4, tailstock 4 tail ends are provided with to be renovated; When renovating closure and tailstock 4 constitute complete external thread, also comprise a nut 5 that the internal thread that cooperates with external thread is arranged.Heat-shrink tube 3 has 2 reinforcements, lays respectively at heat-shrink tube 3 left and right sides.
During concrete the use, prepare earlier, take out heat sealing machine and matched clamp, take out the connector loose mail in the packing, whether inspection lower union joint 2 is intact; Then utilize corresponding anchor clamps to open stripping connector 2 and covered wire cable 6 with driving the stripping pincers respectively; The heat sealing machine of then packing into successively again, welding is accomplished the back and is taken out, and puts pyrocondensation rod 3, and puts into heating region to it, baking good back taking-up; Put tailstock 4 then, and compress optical cable 6 with renovating on the tailstock 4; The nut 5 of screwing on is at last locked, and accomplishes this operation.
After the welding, use the heat-shrink tube 3 of two stainless steel reinforcements that optical cable 6, the bare fibre of the good connector 2 of welding, ceramic core print seat 11 are fixed into integral body, and protection (tailstock 4 is an one with ceramic core print seat 11 clampings) in tailstock 4.For connector tensile strength is strengthened; We have adopted the mode of screw thread to clamp the rubber-insulated wire cable; If single core diameter Ф 3.0MM or diameter Ф 2.0MM optical cable; What we adopted is that the aramid fiber in the optical cable is fixed in the screw thread, makes the present invention no matter continue or continue with traditional indoor cable with the skin cable, and tensile strength can both be more than or equal to 50N.
The utility model utilizes the principle of SC connector to combine with the principle of fused fiber splice; Innovated inner structure; Structure when making whole moving to this connector, the distortion that the optical fiber of avoiding produces at certain space, and then can have influence on the practical effect and the reliability of this product.But also fully take into account the actual situation of user; Hot melting way is still main flow both at home and abroad at present; Mechanical splice still lets and has defectives such as unstable properties, the life-span is short, the field splicing success ratio is low; This has invented positive good utilisation ready-made equipment, very convenient during actual the use, owing to be that the fusing mode unfailing performance that adopts is protected.
Though the present invention is described through embodiment, embodiment is used for limiting the present invention.Those skilled in the art can make various distortion and improvement in the scope of spirit of the present invention, but equally within the protection domain of invention.What therefore protection scope of the present invention should be defined with the application's claim protection domain is as the criterion.
