This kind structure covered wire cable is fixedly the time, and plastic cement sawtooth salient point can be broken because of pulling capacity, easily causes covered wire cable to come off.And pulling capacity is when excessive, and covered wire cable can Yin Lali and pull out, thereby causes Insertion Loss bad.

Summary of the invention

Because the problems referred to above that prior art exists, the purpose of this utility model is to propose a kind of covered wire cable exocuticle fastener, it mainly spins synthetic fibre line and clamp covered wire cable epidermis and clamping by extruding and divides three kinds of mode actings in conjunction of half formula plastic parts to fix covered wire cable, can effectively solve the problems referred to above that prior art exists.

For achieving the above object, a kind of covered wire cable exocuticle fastener of the present utility model comprises an optic fibre guide plastic parts, a metal clip and covered wire cable location guiding plastic parts; Be provided with metal bearing through hole at described optic fibre guide plastic parts front end, and by the spacing and clamping one metal step bearing of this metal bearing through hole, be provided with covered wire cable location guiding plastic parts guide groove and metal clip gathering sill in the rear end, described covered wire cable location guiding plastic parts inserts in the described optic fibre guide plastic parts along this covered wire cable location guiding plastic parts guide groove, and described metal clip snaps in along this metal clip gathering sill and fixes this optic fibre guide plastic parts.

As further feature of the present utility model, described optic fibre guide plastic parts, metal clip, covered wire cable location guiding plastic parts integral body are respectively square structure.

As further feature of the present utility model, the protection of 1.25 ceramic cores groove, bare fibre guide channel and the bare fibre gathering sill that are provided with stopper slot in the described optic fibre guide plastic parts and connect successively.

As further feature of the present utility model, also be provided with square groove on the described optic fibre guide plastic parts, described metal clip gathering sill is located at the side of described optic fibre guide plastic parts; Described metal clip is provided with a plurality of pinches, and it cooperates fixing respectively with described square groove, metal clip gathering sill.

As further feature of the present utility model, described covered wire cable location guiding plastic parts front end is provided with the optical fiber gathering sill, and the middle part is provided with square groove and limited step, and the rear end is provided with covered wire cable and limits groove.

Owing to adopt above technical scheme, covered wire cable exocuticle fastener of the present utility model is compared with existing design, has the following advantages:

1. the utility model fiber alignment can be visual, guarantees that fibre junction is inserted and stable, can not cause disconnected fine and produce extra Insertion Loss;

2. the utility model simplicity of design not only reduces difficulty of processing, and reduces processing cost;

3. the utility model device fixedly during optical cable, repeats loading and unloading without any need for specific purpose tool, and construction intensity is little.

The utility model adopts full hand mode, spins synthetic fibre line and clamp covered wire cable epidermis and clamping by the extruding of metal clip and divides three kinds of mode actings in conjunction of half formula plastic parts to fix covered wire cable, draws towing tension greater than 50N, can fixedly secure.
