Description

technical field [0001] The invention relates to the fields of mechanical engineering and optical communication, and proposes a novel device for fast positioning, clamping and loosening of optical cables. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications, using one or more optical fibers placed in a sheath as a transmission medium, and used individually or in groups. Communication cable assemblies. The optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are components such as a waterproof layer, a buffer layer, and an insulated metal wire as required. [0003] The fixing device of the optical cable is used to clamp the optical cable to prevent the axial movement of the optical cable during tensile, torsion and other mechanical performance tests. It first applies pressure to the outer sheath of the optic...

Problems solved by technology

After the test is over, first screw the bolt back, hold the metal sleeve, open the clamp, peel off the cloth, and take out the optical cable. The operation is cumbersome

When adjusting the bolt to control the friction force, it depends entirely on the subjective judgment of the operator, which is not easy to control accurately, and may cause damage to the optical cable or insufficient clamping force, causing the optical cable to move axially

At the same time, because the replaceable sleeve inside the fixing device is made of metal parts, the friction coefficient with the optical cable is small, and the friction force generated is small. At the same time, the metal hardness is high, which is easy to damage the optical cable, and the way of cloth wrapping is also very irregular. The force is difficult to control accurately, and the work efficiency is low. Based on the existing operation process, it takes about 3 to 4 minutes to complete a full-cycle optical cable clamping and disassembly process, and the work efficiency is very low.
