A kind of mechanical fiber optic cold joint connector
Technical field:
The utility model relates to optical fiber align device technique field, is specifically related to a kind of mechanical fiber optic cold joint connector.
Background technology:
Along with people growing to communication bandwidth requirements, optical fiber has been used for wireline communication network in a large number, needs to carry out a large amount of fibre junction work in the construction of fiber optic network, and traditional fibre junction generally adopts the thermal welding mode of arc heated.The optical fiber cold connection mode generally adopts two fibre junctions of structure realization such as mechanical crimping, and obtains lower connecting loss.Compare with thermal welding, cold joint is continuous to continue easily and fast, need not to carry advantages such as equipment and power supply, the repairing of be fit to that Fiber to the home wiring and optical cable project.
The optical fiber cold connection device that uses in the optical fiber engineering mainly adopts V-type groove structure or capillary pipe structure at present, make two fiber end faces in V-type groove or kapillary, dock, butt joint is afterwards at the cover plate of V-type groove or the both sides plus-pressure of V-type groove, make the distortion of V-type groove clamp bare fibre, and by tightening up optical fiber jacket clamp optical fiber jacket.But the main shortcoming of existing this structure is: clamping force is added on the optical fiber jacket, because clamping device generally adopts plastic material, this material at high temperature can expand, and can draw back two optical fiber, makes connecting loss become big.If optical cable applies pulling force at cold joint connector two ends, the pulling force that applies is in case greater than the friction force of stepping up to produce, and what then optical cable will have no to stop is drawn out.Simultaneously, can't observe the butt joint situation of optical fiber in light optical fiber guiding.
The utility model content:
The purpose of this utility model provides a kind of mechanical fiber optic cold joint connector, and it adopts the method for temperature compensation block, has compensated because the optical fiber that the temperature rising causes is drawn back node.The butt joint situation that the mode of view window can be observed fibre junction point is opened in employing.Employing is from locked claw, thereby tightens up claw, produced the situation of drawing tighter and tighter.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises loam cake 1, base 2, fiber guide 3, skylight 4, groove 5, optical fiber fixed claw 6, temperature compensation block 7, rotary connecting joint 8, described loam cake 1, base 2 is by the hook snap close that is connected, the upper end of loam cake 1 is provided with skylight 4, loam cake 1, the inside of base 2 is provided with groove 5, fiber guide 3 is arranged on loam cake 1, in the groove 5 of base 2 inside, described loam cake 1, the two ends of base 2 are provided with optical fiber fixed claw 6, temperature compensation block 7, optical fiber fixed claw 6, temperature compensation block 7 is fixed on loam cake 1 by rotary connecting joint 8, base 2 two ends.
Described fiber guide 3 is cylinder upper end notching construction.
Described fiber guide 3 can be glass, pottery, metal and fiber optic fibers, plastic guide piece.
The utility model principle of work: when knob was tightened, knob promoted temperature compensation block, and temperature compensation block promotes claw, and claw is owing to the pressure of base and loam cake generation can tighten up, thus the clamping optical cable.When temperature raise, loam cake and base can outwards expand, and the simultaneous temperature compensation block also expands, and the pressure of the generation of expanding is pressed in and makes on the claw that claw inwardly moves, and claw drives the optical cable motion, and the optical fiber that causes is drawn back node because temperature raises thereby compensated.
The utlity model has following beneficial effect: it adopts the method for temperature compensation block, has compensated because the optical fiber that the temperature rising causes is drawn back node.The butt joint situation that the mode of view window can be observed fibre junction point is opened in employing.Employing is from locked claw, thereby tightens up claw, produced the situation of drawing tighter and tighter.

Fig. 1 is the utility model structural representation.
Embodiment:
Referring to Fig. 1, this embodiment is by the following technical solutions: it comprises loam cake 1, base 2, fiber guide 3, skylight 4, groove 5, optical fiber fixed claw 6, temperature compensation block 7, rotary connecting joint 8, described loam cake 1, base 2 is by the hook snap close that is connected, the upper end of loam cake 1 is provided with skylight 4, loam cake 1, the inside of base 2 is provided with groove 5, fiber guide 3 is arranged on loam cake 1, in the groove 5 of base 2 inside, described loam cake 1, the two ends of base 2 are provided with optical fiber fixed claw 6, temperature compensation block 7, optical fiber fixed claw 6, temperature compensation block 7 is fixed on loam cake 1 by rotary connecting joint 8, base 2 two ends.
Described fiber guide 3 is cylinder upper end notching construction.
Described fiber guide 3 can be glass, pottery, metal and fiber optic fibers, plastic guide piece.
Scribble optical fiber coupling cream in the described optical fiber gathering sill, the general transparent material that adopts of optical fiber guiding is so that observe the situation that internal optical fiber continues.
The handshaking procedure of optical fiber align device of the present utility model may further comprise the steps: 1, with the coat of two optical fiber of wire-stripping pliers strip off, expose 125 microns bare fibres, and cleaning optical fiber.2, two optical fiber are penetrated knob, temperature compensation block, claw successively respectively from both sides, penetrate the optical fiber guiding at last, thus the company's of realization root fiber alignment.3, screw knob, knob promotes the temperature oriented module, and the temperature temperature compensation block promotes claw, and claw is owing to the pressure of base and loam cake generation can tighten up, thus the clamping optical cable.
The utility model principle of work: when knob was tightened, knob promoted temperature compensation block, and temperature compensation block promotes claw, and claw is owing to the pressure of base and loam cake generation can tighten up, thus the clamping optical cable.When temperature raises, loam cake and base can outwards expand, and the simultaneous temperature compensation block also expands, and the pressure of the generation of expanding is pressed in and makes on the claw that claw inwardly moves, claw drives the optical cable motion, and the optical fiber that causes is drawn back node because temperature raises thereby compensated.
The utlity model has following beneficial effect: it adopts the method for temperature compensation block, has compensated because the optical fiber that the temperature rising causes is drawn back node.The butt joint situation that the mode of view window can be observed fibre junction point is opened in employing.Employing is from locked claw, thereby tightens up claw, produced the situation of drawing tighter and tighter.
