Abstract

The utility model provides an optical cable terminal box playing fixing and protecting actions at the junction of an optical cable and a pigtail fiber. The utility model is characterized in that a junction of an optical cable fiber core and a pigtail fiber core are protected through a steel core thermal shrinkage protection tube. An optical cable fixing seat block anchor ear and a fiber plate cover are both provided with a latex foam sheet, playing the protective action of fixing, anti-vibration and anti-damage. The utility model has the advantages of low cost and reasonable design, suitable for junctions of an optical cable terminal less than 60 cores and a pigtail fiber.

Description

GPZ

The utility model relates to a kind of termination box, particularly optical cable and there is GPZ fixing and protective effect the tail optical fiber junction.

Termination box of the prior art, the fibre core dish stays big inadequately, and the bending radius of fibre core causes attenuation value bigger than normal less than the requirement of fibre core bending techniques in the fibre core dish, the quality of influence transmission; Optical cable and tail optical fiber is fixing not firm among some termination box, and when external force carrying optical cable or tail optical fiber, fibre core is vibrated easily in the box, gently then influences transmission quality, and the heavy then disconnected fibre core that shakes interrupts transmitting.

The purpose of this utility model is intended to avoid deficiency in the prior art and provides a kind of convenient and practical, GPZ firm and with low cost.

The purpose of this utility model is achieved in that

A kind of GPZ; it is characterized in that by stainless steel box body, aluminium sheet fibre core dish, soft rubber winding displacement groove, tail optical fiber inlet wire plate, optical cable inlet wire plate, optical cable fixed head, fixedly the optical cable anchor ear, fixedly optical cable pine protecting pipe, steel core pyrocondensation protection tube, fine disk cover plate and optical cable fixedly saddle anchor ear etc. form, wherein:

(1) 12 wire casing ditches is arranged in the soft rubber winding displacement groove, the 1-5 that is arranged in parallel row;

(2) tail optical fiber inlet wire plate is fixed on the box body with CARBURIZING FURNACE FOR STAINLESS FASTENER, 1-5 row aperture is arranged, every row 1-12 hole;

(3) optical cable inlet wire plate is formed by a monoblock or by 1 bulk and the split of 1-6 fritter, and the centre has 1-6 to enter the cable hole to be fixed on the box body with CARBURIZING FURNACE FOR STAINLESS FASTENER;

(4) 1-6 half slot arranged in the middle of the optical cable fixed head;

(5) fixedly optical cable anchor ear bottom surface and optical cable surface of contact are stained with the sponge film;

(6) steel core pyrocondensation protection tube is used to protect optical cable fibre core and tail optical fiber fibre core junction, and it is embedded soft rubber winding displacement groove, covers with fine disk cover plate and is fixed.

---the surface of contact of described fine disk cover plate bottom surface and steel core pyrocondensation protection tube all posts the sponge film.

---described optical cable fixedly saddle anchor ear inner face also is pasted with the sponge film that shields.

Below in conjunction with drawings and Examples the utility model is further described;

Fig. 1 is the utility model general assembly structural drawing;

Fig. 2 is a tail optical fiber inlet wire plate elevation view, has 1-3 to arrange 12 heart yearn grooves;

Fig. 3 is an optical cable inlet wire plate elevation view;

Fig. 4 is an optical cable fixed head cut-open view, and the sponge film is arranged in the two halves ring recess;

Fig. 5 sponge film (under fixing compressing tablet 9-1) synoptic diagram;

Fig. 6 is that sponge film synoptic diagram is pasted in fine disk cover plate bottom surface.

1 is the stainless steel box body among the figure, and 2 is aluminium sheet fibre core dish, 2-1 fibre core dish ear (fixedly cable dish fibre core is used); 3 is soft rubber winding displacement groove, and 4 is tail optical fiber inlet wire plate, and 5 is optical cable inlet wire plate; 6 is the optical cable fixed head, and 7 are fixing optical cable anchor ear, and 7-1 is a screw; 8 are screw (screw rod in the middle of have 2 holes), and 9 be soft rubber winding displacement groove, and 9-1 is fixing compressing tablet; 10 are the loose protecting pipe of fixing optical cable; 11 is tail optical fiber, and 12 is optical cable, and 12-1 is an optical cable pine protecting pipe; 12-2 is the optical cable fibre core; 12-3 is an optical cable strengthening core, and 13 are the protection ground wire, and 14 is steel core pyrocondensation protection tube; 15 is the fixed bin body opening; 16 are fixing ground wire hole, and 17 be that box body coils connecting hole with fibre, and 18 is fine disk cover plate bottom surface.

Implementation process: optical cable is entered in the box body, fix with the optical cable anchor ear, strengthening core is fixed with φ 12mm screw and is connected the protection ground wire, pine sheath fibre core has two places to fix with nylon cable tie in fiber reel, the optical cable fibre core coils to embed in the soft rubber wire casing after a week in dish again and is connected (with the protection of pyrocondensation protection tube) with the tail optical fiber fibre core, the tail optical fiber fibre core coils a circle after soft rubber winding displacement groove is fixed with fixing compressing tablet in fiber reel, draw through the tail optical fiber fairlead and to insert fiber optic again, optical cable is fastening with two φ 16mm screws with optical cable holder piece and anchor ear; Fixedly the sponge film of saddle and optical cable anchor ear inner face plays fixedly antivibration, measuring body protective effect, errorless on inspection after, cover fine disk cover plate and fix with box body.

The utility model is made of stainless steel and organic glass, termination box than import is inexpensive, the fiber reel dish of design is stopped enough big, fibre core coiling bending radius is greater than 2.5cm, surpass the fibre core bending techniques and require (125 μ m * 40 times), there are optical cable and tail optical fiber solid and reliable again, do not damage fibre core, not influenced by external force vibration at the termination box internal fixation.
