Embodiment
Below in conjunction with accompanying drawing 1-8 and specific embodiment, invention is described in further detail:
A kind of optical cable is drawn and is connect distributing cabinet, comprises casing 1, is arranged on the chamber door 5 in casing 1 front, upper reason coil holder 13, tap frame 6, lower reason coil holder 14 and the remaining coil holder 7 be arranged on from top to bottom in casing 1, is arranged on being used for drawing and connecing drawing of optical cable 8 and connect hole 2 and side fixed mount 15 and draw the plugging mechanism connecing hole 2 for shutoff on casing 1 sidewall 11;
The upper trunking 132 that described upper reason coil holder 13 is formed by upper reason line tooth 131 and adjacent upper reason line tooth 131 is formed; Described tap frame 6 is made up of " V " shape draw-in groove 61 and the jump ring 62 be arranged on " V " shape draw-in groove 61 liang of madial walls; The lower trunking 142 that described lower reason coil holder 14 is formed by lower reason line tooth 141 and adjacent lower reason line tooth 141 is formed; Described remaining coil holder 7 comprises reason terminal 71, is fixedly installed the main fixed mount 72 of resonable terminal 71 front end; Described side fixed mount 15 is fixedly installed on casing 1 sidewall; Described drawing connects hole 2 and is arranged on casing 1 diapire;
Described drawing connects hole 2 side and is provided with and more than onely crosses line case breach 21 and case screw 12, described plugging mechanism comprises: baffle plate 3, be arranged on the fixed strip 31 of baffle plate 3 side, what be arranged on baffle plate 3 side crosses line plate breach 32 and O-ring seal, described fixed strip 31 is provided with plate screw 33, described plate screw 33 is corresponding with case screw 12, described line plate breach 32 of crossing is corresponding with case breach 21 and form string holes, described O-ring seal comprises: " C " type rubber cushion 4 of a side opening and with rubber cushion 4 with the use of glue wedge 41, described rubber cushion 4 is provided with board slot 42, described glue wedge 41 is provided with wedge groove 43, described board slot 42 is corresponding with wedge groove 43, the annular groove that described board slot 42 wedge groove 43 is formed and string holes match.Drawing and connecing hole 2 is rectangles, and described case breach 21 is two, and is separately positioned on the minor face drawing and connect hole 2 correspondence, and to be rectangles connect hole 2 and match with drawing described baffle plate 3, and described plate breach 32 is two and formation corresponding with case breach 21 two string holes.Case screw 12 is evenly arranged on to draw and connects on long limit corresponding to 2 two, hole, described plate screw 33 and case screw 12 one_to_one corresponding.Fixed strip 31 lateral surface is fixedly connected with baffle plate 3 medial surface, and described baffle plate 3 is identical with sidewall 11 thickness.
Optical cable entirety drawn in inlet body 1, carry out tap operation, optical cable discrepancy casing is sealed by O-ring seal, do not need the optical fiber of tap directly fixing, be fixed to after needing the optical fiber of tap to cut open on tap frame, lateral fiber directly with treat that tapping fiber cable welds, just can complete optical cable tap; Avoid unnecessary optical fiber disjunction and welding, not only decrease workload and work difficulty, also shorten work period and construction cost, inherently improve owing to welding the signal attenuation brought.
For adapting to new body structure, new construction method must be used, reducing welding job amount, simplify and use step, increase work efficiency.
Implement by the following method during casing practicality construction, a kind of tapping fiber cable does not cut off construction method, implements according to the following steps: the first step: will the optical cable 8 of tap be needed to reserve sufficient length, and the light arranging technical scheme is herein drawn and connect case;
Second step: optical cable cartonning,
1) complete optical cable 8 is connect hole 2 draw in casing 1 by drawing;
2) respectively two rubber cushions 4 are stuck in the position that optical cable 8 enters casing 1, then are in place by two glue wedges 41, wrapped by cable together with rubber cushion 4, board slot 42 wedge groove 43 correspondence becomes annular groove;
3) annular groove that two O-ring seals are formed is stuck on plate breach 32, by inside casing 1, the plate breach 32 of baffle plate 3 is stuck in annular groove;
4) by case screw 12 and plate screw 33, baffle plate 3 is fixed on the sidewall 11 of casing 1 by outside casing 1 with screw;
3rd step: the optical cable 8 entering casing 1 is fixed on the main fixed mount 72 of casing 1 diapire;
4th step: strip off optical cable 8 external insulation is protected, and is fixed on the reason terminal of remaining coil holder 7 by not needing the optical fiber of tap;
5th step: tap:
1) will the optical fiber of tap be needed to cut off, and be fixed in the upper and lower trunking 142 of lower reason line tooth 141 of lower reason coil holder 14, the optical fiber free end cut off be for subsequent use;
2) tap cable enters in casing 1 by the string holes on wall box, fixes, then arrive casing 1 top, strip off cable external protection via side fixed head 15;
3) tap optical fiber free end will be needed, on the upper reason line tooth 131 being fixed on reason coil holder 13 and for subsequent use in upper trunking 132;
4) needing the naked fibre of welding through the process of nanometer pincers, having been welded by tap optical fiber through special optical fiber splicer, installing sheath additional;
5) by sheath holding in " V " shape draw-in groove 61 of tap frame 6, fixed by jump ring 62;
6th step: close chamber door 5, complete operation.
For adapting to new body structure, new construction method must be used, reducing welding job amount, simplify and use step, increase work efficiency; Drawing and connect hole 2 inner side edge can also be device for fixing screen on headrest, be used for quantity diameter not wait turnover cable.
