Background technology
Optical cable is the prevailing transmission medium of optical communications industry, and optical fiber loose tube is the important composition part of optical cable, to ensure the performance of optical cable, optical fiber has a range of remaining long in Loose tube, for needing first to detect its excess fiber length before next procedure production after Loose tube production in production process, further according to the technique that remaining long result determines next procedure.And detect long mode more than sleeve pipe at present typically all using pure manual type, i.e., directly with scissors sleeve pipe is cut off on disk, then manually stretch and measured on meter ruler.This mode is different due to the dynamics that different people is used so that remaining long testing result can have larger error, affects the setting of next procedure technique.
The content of the invention
It is an object of the invention to overcome the defect of prior art, there is provided one kind can make optical fiber loose tube customized cut-off under constant-tension state, the error that human factor is caused is reduced, it is ensured that testing conditions conforming remaining long detection means during different human users.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
Remaining long detection means, excess fiber length for optical fiber loose tube is detected, the device has a supporting table, scale is provided with supporting table, 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 stretched along length of the scale direction and is connected with a balancing weight, and balancing weight is by a pulley stretch optic fibre Loose tube；One cutting knife is distributed in optical fiber loose tube and stretches on direction, and cutting knife is used to cut off optical fiber loose tube.
Such scheme is further：The balancing weight connects a clip by steel wire rope, and steel wire rope is located at pulley, the respective end of clip grip optical fiber Loose tube.
Such scheme is further：A safety rope is drawn on the pulley, the safety rope system connects balancing weight or steel wire rope.
Such scheme is further：The scale and supporting table integral production combine formation.
The present invention utilizes balancing weight stretch optic fibre Loose tube, optical fiber loose tube customized cut-off under constant-tension state can be made, the error that human factor is caused is reduced, it is ensured that the uniformity of testing conditions during different human users, advantageously arrange in the technique for instructing next procedure, improve the yield rate of product.
Further advantage of the present invention is simple structure, and cost of investment is low, easy to operate, meets industry utilization and extention.
Description of the drawings：
Accompanying drawing 1 is one example structure schematic diagram of the present invention.
Specific embodiment：
The technique effect of the design, concrete structure and generation of the present invention is described further below with reference to accompanying drawing, to be fully understood from the purpose of the present invention, feature and effect.
Refering to shown in Fig. 1, being presently preferred embodiments of the present invention schematic diagram, the present invention is about a kind of remaining long detection means, excess fiber length for optical fiber loose tube is detected, the device has a supporting table 1, is provided with scale 2 in supporting table 1, scale 2 and the integral production of supporting table 1 or combines formation.Compressing member 3 is provided with 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 stretched along the length direction of scale 2 and is connected with a balancing weight 5, balancing weight 5 by the stretch optic fibre Loose tube 4 of a pulley 6, make optical fiber loose tube can under constant-tension state fixed length.One cutting knife 7 is distributed in optical fiber loose tube 4 and stretches on direction, and cutting knife 7 is used to cut off optical fiber loose tube 4, to obtain the optical fiber loose tube length of needs.The structure can reduce the error that human factor is caused, it is ensured that the uniformity of testing conditions during different human users, advantageously arrange in the technique for instructing next procedure, improve the yield rate of product.
Shown in Fig. 1, the balancing weight 5 of the present embodiment connects a clip 8 by steel wire rope 51, and steel wire rope 51 is located at pulley 6, the respective end of the grip optical fiber Loose tube 4 of clip 8.And a safety rope 61 is drawn on pulley 6, the safety rope 61 is to connect balancing weight 5 or steel wire rope 51.Detection Yu Changshi, first one end of optical fiber loose tube 4 is pulled to into the left alignment with scale 2, then the pressed fiber Loose tube 4 of compressing member 3 is passed through, and the other end of optical fiber loose tube 4 is pulled at pulley 6, the other end of optical fiber loose tube 4 is clamped by clip 8, in the presence of balancing weight 5, optical fiber loose tube 4 is straightened, and Jing after scale 2 is measured, cutting knife 7 cuts off optical fiber loose tube 4 in relevant position, obtain the optical fiber loose tube 4 of fixed length, then optical fiber therein, the length of detection fiber are further taken out, it is assumed that the length of optical fiber loose tube 4 is L, the length of optical fiber is L1, then（L1-L）/ L*1000 ‰, that is, obtain optical fiber excess length in optical fiber loose tube 4.Balancing weight 5 is connected with clip 8 by steel wire rope 51, bypasses pulley 6, and the steel wire rope 51 between a connection balancing weight 5 of safety rope 61 and clip 8 is drawn at the heart axle of pulley 6（Certainly safety rope 61 can also connect balancing weight 5）, safety rope 61 is in unstrained state, when cutting knife 7 cuts off optical fiber loose tube 4, balancing weight 5 can fall down, then the safety rope 61 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.
