[0003] However, in actual use, the twisted pair wires used for signal transmission will inevitably be bent and twisted, so the lay length of the twisted wires will inevitably change, and the two insulated wires will inevitably be partially loose and misplaced, resulting in the failure of external interference signals offset, the signal transmission quality of the twisted-pair cable is not guaranteed

[0073] figure 1 Provides a front view of equipment for securing twisted-pair cable lay, including:
[0074] pay-off system 20 for conveying two separable sheathed wires;
[0075] The ultrasonic plastic welding machine 10 is used to weld the sheath of the wire conveyed by the pay-off system 20, so that the two wires form an inseparable cable;
[0076] and a wire take-up system 30 for twisting the cable according to a predetermined laying distance to form a twisted pair cable, and winding the twisted pair cable;
[0077] A control system (not shown), which is respectively connected with the wire pay-off system 20 , the ultrasonic plastic welding machine 10 and the wire take-up system 30 , for controlling the wire pay-off system 20 , the ultrasonic plastic welding machine 10 and the wire take-up system 30 operation.
[0078] Further, combining Figure 2-3 It can be seen that the pay-off system 20 includes:
[0079] Two wire rolls 21, which can be used for winding two wires; ...

Abstract
The invention discloses a device and a method for fixing twisted-pair cable laying distance. The device comprises a pay-off system for conveying two detachable sheathed wires; An ultrasonic plastic weldingmachine for welding the sheath of the wire to form an inseparable cable; and an ultrasonic plastic weldingmachine for twisting the cable according to a predetermined lay length to form a twisted pair cable, and performing the twisting on the twisted pair cable. Winding take-up system. The method includes wire assembly, wire welding, twisted pair cable fabrication, and twisted pair cable winding. The invention adopts ultrasonic plastic weldingmachine to melt and weld the sheath of the wire to make it into an inseparable cable, and further twist the cable according to a predetermined twisting distance to form a twisted pair cable, so as to ensure the twisted pair The wire lay length does not change during use, and the two wires of the twisted pair will not be partially loosened and misaligned, so as to improve the quality of signal transmission.
Description
technical field [0001] The present invention relates to wire and cable technology, in particular to a device and method for fixing twisted-pair cable lay length. Background technique [0002] Twisted pair cables are widely used in various electrical equipment as power, especially signal transmission elements. In modern communication, sensing and control technology, electromagnetic interference in the air and lines is everywhere, which seriously affects the quality of signal transmission, especially in microelectronic circuit transmission and long-distance transmission, electromagnetic interference will cause signal distortion. Therefore, the signal transmission line must have the necessary ability to shield electromagnetic interference. In the prior art, twisted pair cables are usually used to overcome the above problems, that is, two insulated wires are twisted into a spiral shape, so that they are combined with each other, so that the back and forth The interference gener...
