Description

Technical Field

[0001] The present invention relates to a twisted-pair cable processing system, a cutting method for cutting a pair of core wires of a twisted-pair cable using the twisted-pair cable processing system, and an untwisting method for untwisting a pair of core wires of a twisted-pair cable using the twisted-pair cable processing system. Background Art

[0002] In the prior art, when it is necessary to crimp terminals on a pair of exposed core wires of a twisted-pair cable, the outer sheath at one end of the twisted-pair cable needs to be removed so that the pair of core wires at one end of the twisted-pair cable are exposed. The exposed pair of core wires of the twisted-pair cable are then untwisted manually. The exposed pair of core wires then need to be cut so that the length of the exposed pair of core wires is equal to a predetermined length. In the prior art, the twisted-pair cable is first manually placed and positioned on a clamping mechanism, and then the exposed pair of core wires of the twisted-pair cable is cut using a cutting mechanism. The length of the exposed core wires of the twisted-pair cable after cutting depends on whether the cable can be placed in the predetermined position on the clamping mechanism. Since the cut end surface of the outer sheath of the twisted-pair cable is not necessarily very flat, it is sometimes impossible to place the twisted-pair cable in the predetermined position, resulting in a large deviation between the length of the exposed pair of core wires of the twisted-pair cable after cutting and the predetermined length.

[0003] Furthermore, in the prior art, since a pair of core wires of a twisted-pair cable needs to be untwisted manually, production efficiency is reduced. Summary of the Invention
