Problems solved by technology

[0003] Since the optical cable is easily subjected to mechanical loads such as bending and torsion during use, if the torsion resistance of the produced optical cable is not good enough, after repeated torsion and bending, the cable core of the optical cable will fail due to conductor breakage, and This kind of fracture has no external traces, so a large-scale fault detection cannot be carried out, and the user cannot find out the area where the accident is located, which greatly affects the electricity consumption in related fields, so the torsion test after the production of optical cables is very important.

Embodiment 1

[0038] The invention discloses a special communication optical cable torsion test system, such as figure 1 Shown, comprise frame platform 1, also comprise the torsion box 2 that is arranged on one end of the upper surface of frame platform 1, be arranged on the torsion driving device 3 in the torsion box 2, rotate and be arranged on the side wall of the torsion box 2 working surfaces and The twisting head 4 connected to the driving end of the twisting drive device 3, the tensioning slide 5 that is arranged on the opposite side of the frame table 1 and the working surface of the twisting box 2, the tensioning slide 5 and the twisting head 4 in the present invention The shortest optical cable detection length is one meter. Meanwhile, the frame platform 1 of the present invention is also provided with a guide rail for sliding the tensioning slide 5 and a distance between the tensioning slide 5 and the twisting head 4. Scale, the present invention is also arranged on the tightenin...

Embodiment 2

[0045] A special communication optical cable torsion test system, such as image 3 As shown, the difference between Embodiment 2 and Embodiment 1 is that in order to improve the fixing strength at both ends of the optical cable, in the present invention, the clamping groove 17 includes a straight groove 26 arranged on the side of the clamping block 16 away from the twisting head 4 , the straight groove 26 extends along the extension direction of the optical cable, and also includes a twisted groove 27 arranged on the side of the clamping block 16 close to the twist head 4, and the straight groove 26 communicates with the twisted groove 27; the two ends of the optical cable are put into In the straight groove 26 and the twisted groove 27, and then the twisted groove wall of the twisted groove 27 can limit the optical cable, strengthen the force on the optical cable along the extending direction of the optical cable, and avoid the two sides of the optical cable during the test. ...

Embodiment 3

[0047] A special communication optical cable torsion test system, such as Figure 4 , Figure 5 and Figure 6 As shown, the difference between the third embodiment and the first embodiment is that the various clamps 10 include clamp seats 34 respectively arranged on the torsion head 4 and the tensioning slide 5, and guides arranged on the opposite side walls of the two clamp seats 34. Groove 35, the introduction groove 35 extends along the extension direction of the optical cable, and also includes the same accommodating chamber 36 as the introduction groove 35 arranged in the clamp seat 34, and the 270 ° clamping fan disk 37 that is horizontally rotated and arranged in the accommodating chamber 36. The radial side wall of the 270° fan-shaped turntable in the initial state is in the same direction as the extension direction of the optical cable, and also includes a 90° clamping fan disk 38 and a 270° clamping fan that are slid and arranged in the accommodation cavity 36 along...

Abstract

The invention, which relates to the field of optical cable performance testing, discloses a special communication optical cable torsion test system and aims at providing a testing machine capable of carrying out fast and stable torsional tests on optical cables with different thicknesses. The test system comprises a rack bench, a torsion box arranged at one end of the upper surface of the rack bench, a torsion drive device arranged in the torsion box, a torsion head being arranged on the side wall of the working surface side of the torsion box in a rotating manner and being connected with a drive end of the torsion drive device, a tightening sliding base arranged at one side, opposite to the working surface of the torsion box, of the rack bench in a sliding manner, a tightening guide wheelarranged at one end, away from the working surface of the torsion box, of the rack bench, a tensioning rope arranged between the tightening guide wheel and the tightening sliding base in a sliding manner, a weight hook seat arranged at one end, going around the tightening guide wheel and being away from the tightening sliding base, of the tensioning rope, and diversified clamps being arranged atthe torsion head and the tightening sliding base and being used for fixing optical cables. Therefore, fast and stable torsional tests on optical cables with different thicknessescan be realized by onemachine.

Description

technical field [0001] The invention relates to the field of optical cable performance detection, more specifically, it relates to a special communication optical cable torsion test system. Background technique [0002] The special communication optical cable is composed of a core, a protective layer and an outer sheath composed of several optical fibers (generally ranging from several cores to thousands of cores). It is used at a specific wavelength, made of special materials and has special functions. [0003] Since the optical cable is easily subjected to mechanical loads such as bending and torsion during use, if the torsion resistance of the produced optical cable is not good enough, after repeated torsion and bending, the cable core of the optical cable will fail due to conductor breakage, and This kind of fracture has no external traces, so a large-scale fault detection cannot be carried out, and the user cannot find out the area where the accident is located, which g...
