Description
Technical field
The utility model relates to fiber optic cable production technical field, especially the excess fiber length detection technique field of optical fiber loose tube.
Background technology
Optical cable is the prevailing transmission medium of optical communications industry, and optical fiber loose tube is the important composition parts of optical cable, for ensureing the performance of optical cable, optical fiber has more than certain limit long in Loose tube, in production run, Loose tube needs first to detect its excess fiber length before producing for next procedure after producing, then according to the technique of remaining long result determination next procedure.And at present the remaining long mode of detection thimble generally all adopts pure manual type, namely on dish, direct scissors cuts off sleeve pipe, more manually stretchingly measures on meter ruler.The dynamics that this mode uses due to different people is different, makes remaining long testing result can there is larger error, affects the setting of next procedure technique.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides one can make optical fiber loose tube customized cut-off under constant-tension state, reduces the error that causes of human factor, testing conditions conforming remaining long pick-up unit when ensureing different human users.
For achieving the above object, the utility model adopts following technical scheme:
Remaining long pick-up unit, excess fiber length for optical fiber loose tube detects, this device has a brace table, brace table is provided with scale, one termination of scale is provided with compressing member, one end of optical fiber loose tube is fixed by compressing member, and the other end of optical fiber loose tube is then stretching along length of the scale direction and be connected with a balancing weight, and balancing weight is by a pulley stretch optic fibre Loose tube; One cutting knife is distributed on the stretching direction of optical fiber loose tube, and cutting knife is for cutting off optical fiber loose tube.
Such scheme is further: described balancing weight connects a clip by wire rope, and wire rope is located at pulley, the respective end of clip clamping optical fiber loose tube.
Such scheme is further: described pulley is drawn a safety rope, this safety rope system connects balancing weight or wire rope.
Such scheme is further: described scale and brace table integral production or be combined to form.
The utility model utilizes balancing weight stretch optic fibre Loose tube, optical fiber loose tube customized cut-off under constant-tension state can be made, reduce the error that human factor causes, ensure the consistance of testing conditions during different human users, advantageously in instructing the technique of next procedure to arrange, improve the yield rate of product.
A utility model again advantage is that structure is simple, and cost of investment is low, easy to operate, meets industry utilization and extention.
accompanying drawing illustrates:
Accompanying drawing 1 is the utility model one example structure schematic diagram.
embodiment:
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Consulting shown in Fig. 1, is preferred embodiment schematic diagram of the present utility model, the relevant a kind of remaining long pick-up unit of the utility model, excess fiber length for optical fiber loose tube detects, this device has a brace table 1, and brace table 1 is provided with scale 2, and scale 2 is with brace table 1 integral production or be combined to form.Compressing member 3 is provided with in a termination of scale 2, one end of optical fiber loose tube 4 is fixed by compressing member 3, the other end of optical fiber loose tube 4 is then stretching and be connected with a balancing weight 5 along scale 2 length direction, balancing weight 5 by a pulley 6 stretch optic fibre Loose tube 4, make optical fiber loose tube can under constant-tension state fixed length.One cutting knife 7 is distributed on the stretching direction of optical fiber loose tube 4, cutting knife 7 for cutting off optical fiber loose tube 4, to obtain the optical fiber loose tube length of needs.This structure can reduce the error that human factor causes, and ensures the consistance of testing conditions during different human users, advantageously in instructing the technique of next procedure to arrange, improves the yield rate of product.
Shown in Fig. 1, the balancing weight 5 of the present embodiment connects a clip 8 by wire rope 51, and wire rope 51 is located at pulley 6, the respective end of clip 8 grip optical fiber Loose tube 4.And on pulley 6, draw a safety rope 61, this safety rope 61 is connect balancing weight 5 or wire rope 51.Detect Yu Changshi, first one end of optical fiber loose tube 4 is pulled to the left justify with scale 2, then by compressing member 3 pressed fiber Loose tube 4, and the other end of optical fiber loose tube 4 is pulled to pulley 6 place, by the other end of clip 8 grip optical fibers Loose tube 4, under the effect of balancing weight 5, optical fiber loose tube 4 is straightened, after scale 2 measures, cutting knife 7 cuts off optical fiber loose tube 4 in relevant position, namely the optical fiber loose tube 4 of fixed length is obtained, and then the optical fiber taken out wherein, the length of detection fiber, suppose that the length of optical fiber loose tube 4 is L, the length of optical fiber is L1, then (L1-L)/L*1000 ‰, namely optical fiber excess length in optical fiber loose tube 4 is obtained.Balancing weight 5 is connected by wire rope 51 with clip 8, walk around pulley 6, draw the certain safety rope 61 of wire rope 51(that a safety rope 61 connects between balancing weight 5 with clip 8 at the axle place of pulley 6 and also can be connected balancing weight 5), safety rope 61 is in unstrained state, when cutting knife 7 cuts off optical fiber loose tube 4 time, balancing weight 5 can fall down, namely safety rope 61 then on pulley 6 can be in tensioning state when balancing weight 5 drops to certain altitude, hold balancing weight 5, prevent balancing weight 5 from dropping to the ground and break or hurt sb.'s feelings.
