A fiber deployment jig for double card position, is characterized in that, this fiber deployment jig comprises screw, the first nut, C type jig, the second nut, clip assembly, the 3rd nut and screw rod; Screw passes a sidewall of the first nut and C type card, stretches into C type jig inner; Screw rod is successively through another sidewall being fixed on C type jig after the 3rd nut, clip assembly, the second nut;
Clip assembly is made up of plastics fastener and two rubber sheaths, plastics fastener is made up of the first fastener of symmetrical shape and the second fastener, all have mounting hole and two semicylindrical openings in first fastener and the second fastener, the semicylindrical opening that the first fastener is relative with position after the second fastener combination is combined into cylindrical hole; Two cylindrical hole axis are parallel to each other, and two cylindrical holes are with mounting hole axis is mutually vertical and not at same plane, two cylindrical holes are distributed in mounting hole axis both sides; Mounting hole is unthreaded hole, after screw rod penetrates mounting hole, has gap between mounting hole hole wall and screw rod; Two rubber sheaths are respectively charged into two cylindrical holes of same plastics fastener; Manhole in rubber sheath is for placing optical fiber.
Preferably, this fiber deployment jig comprises cushion pad further, is arranged on the end that screw stretches into C type jig inside.
Preferably, two cylindrical holes in plastics fastener are arranged relative to mounting hole rotational symmetry.
Preferably, between described second nut and clip assembly, plain cushion and bullet pad are installed; 3rd also installs plain cushion and bullet pad between nut and clip assembly.
Preferably, screw overlaps with screw axis.
Beneficial effect:
The utility model is closely fixed on by geodesic structure by C type card and screw rod, sensor fibre is through rubber sheath, then by nut, sensor fibre is tightly wrapped in rubber sheath, ensure sensing optical fiber and kept by geodesic structure being out of shape consistent, and can the tightness that sensing optical fiber is fixed to be regulated.
The fixing of more optical fiber can be provided by arranging multiple clip assembly simultaneously.
