Description
Technical field
The utility model relates to the connector technique field, particularly a kind of fusing type optical fiber quick connector.
Background technology
In optical communication network, often need to continue to optical fiber, fibre junction has generally dual mode: a kind of is the cold joint mode, can not use the dress instrument, can be succinctly fast mode optical fiber is flexibly connected, but shortcoming be decay larger, disconnected fine easily, in case break down, difficulty is searched reparation; Another kind is the welding mode, generally be in fusion joining disk with behind the fused fiber splice, at tail end optical fiber is carried out the end face connector again and makes, carry out secondary and connect, its advantage is firm and reliable connection, shortcoming is that the secondary link cost is high, efficient is low.How effectively to solve the defective and the deficiency that exist in the existing fiber continuation method, become the focus of research in the industry.
The utility model content
The purpose of this utility model be to provide a kind of easy and simple to handle, connect accurately, signal attenuation is very little, merging precision is high and solid and reliable optical fiber quick connector.
For achieving the above object, the utility model is by the following technical solutions:
A kind of fusing type optical fiber quick connector described in the utility model, comprise ceramic insertion core, fixed cover, casing seat and heat-shrink tube, described ceramic insertion core one end is inserted in the fixed cover, the ceramic insertion core other end is inserted in the casing seat, described casing seat is arranged with support seat near on fixed cover one end, the casing seat middle part is arranged with spring, be arranged with rear branch holder on the described spring, described heat-shrink tube one end is located in the casing seat, and the heat-shrink tube other end places in the rear branch holder, and described fixed cover is arranged with shell outward.
Further, be provided with dust cap between described ceramic insertion core outer end and the fixed cover.
Further, described rear branch holder outer end is provided with the toothholder mouth, and described toothholder mouth is provided with the tail cover outward.
Further, the longitudinal angle of clip tooth is 7～8 degree in the described toothholder mouth.
The utility model beneficial effect is: when fibre junction, the utility model will be originally need to welding and fixing in fusion joining disk, carry out again secondary and connect, being optimized to does not need fusion joining disk and directly fusion point is put into connector construction and connect.When carrying out the optical fiber continued access with the utility model, reduce the optical fiber tie point, thereby directly reduced the trouble spot, reduced the decay of light contact.The utlity model has and save cost, connection is accurate, solid and reliable, signal attenuation is little and merging precision is high advantage.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of fusing type optical fiber quick connector described in the utility model comprises ceramic insertion core 4, fixed cover 3, casing seat 5 and heat-shrink tube 8, spring 6, rear branch holder 9 and shell 2.Above-mentioned parts consist of the utility model agent structure.
When connecting with the utility model, be provided with optical fiber in the described ceramic insertion core 4, the optical fiber of ceramic insertion core 4 one ends is convenient to socket connection through the PC end face of gluing and solidifying, grinding moulding; Ceramic insertion core 4 other ends are inserted in the casing seat 5, and the optical fiber that ceramic insertion core 4 inserts the end in the casing seat 5 stretches out ceramic insertion core 4 end faces and passes casing seat 5, stretches out preferred Φ 0.9 tight tube fiber of optical fiber of ceramic insertion core 4 end faces.Covered wire cable one end that needs to connect penetrates in the rear branch holder 9 from rear branch holder 9 rear ends, covered wire cable penetrates to be put into heat sealing machine with the optical fiber that passes casing seat 5 behind the front cutting crust of ends in the rear branch holder 9 and carries out the arc heat welding, be provided with heat-shrink tube 8 in the welding outsourcing again, again heat-shrink tube 8 pyrocondensation on heat sealing machine is fixed, optical fiber is connected reach the permanent technique effect that firmly connects.After connecting, described heat-shrink tube 8 can place in the casing seat 5, in order to it effectively is coated and fixed.
The end that described ceramic insertion core 4 is provided with the PC end face is inserted in the fixed cover 3, in order to tighten up ceramic insertion core 4.Be provided with dust cap 1 between described ceramic insertion core 4 outer ends and the fixed cover 3, reach dustproof technical purpose.Be provided with shell 2 outside the described fixed cover 3, can play preventing effect.
Described casing seat 5 is arranged with support seat 7 near on fixed cover 3 one ends, and casing seat 5 middle parts are arranged with spring 6, reach the technical purpose of fixed sleeve base 5.Described spring 6 tightens cover rear branch holder 9.
Described rear branch holder 9 outer ends are provided with toothholder mouth 10, and the described toothholder mouth 10 outer tail covers 12 that are provided with can effectively tighten up covered wire cable.For further tightening up covered wire cable, avoid move left and right, be provided with clip tooth 11 in the described toothholder mouth 10, described clip tooth 11 embeds in the leather sheath of covered wire cable, plays good fixation.
The longitudinal angle of described toothholder mouth 10 interior clip tooths 11 is 7～8 degree, after in the leather sheath of embedding covered wire cable, toothholder mouth 10 interior up and down both sides have the crown section of clip tooth 11 substantially to be on two parallel lines, and it is consistent that crown embeds the interior degree of depth of leather sheath, both reached and clamped, do not injure again the effect of optical fiber.
A kind of fusing type optical fiber quick connector described in the utility model, adopt front end ceramic insertion core 4 guide-localizations, the middle-end welding is also passed through heat-shrink tube 8 fixed fibers, rear end clip tooth 11 clamps the structure of covered wire cable external diameter, leading portion has spring 6 in it, keep a constant elastic pressure, guaranteed the stability of fiber alignment.Because the high precision that ceramic insertion core 4 has guiding, guaranteed good alignment precision, because the welding mode has been adopted in the stage casing, aligning out of true that other cold joint mode produces, shortcoming that decay is large have been overcome, add heat-shrink tube 8, make its intensity with the same without the breakpoint optical cable, overcome and resolve fine obstructed common deficiency, the covered wire cable that back segment clip tooth 11 clamps outdoor introducing clamps unlikely getting loose, and above structure has low decay, high precision docking, connects accurately and reliably technique effect.
The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
