Problems solved by technology

[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

Embodiment 1

[0070] Figure 1-2 Provides front and top views of equipment for fixing the lay length of twisted-pair cables, including:

[0071] Pay-off system 20, used to transport two exposed wires C;

[0072] The extruder 10 is used to extrude each of the exposed wires C conveyed by the pay-off system 20, so that they have sheaths respectively, and the sheaths are connected to form a one-piece sheath, so that the Conductor C becomes a cable with a one-piece sheath;

[0073] and a wire take-up system 30, configured to twist the cables according to a predetermined lay length to form twisted-pair cables, and wind up the twisted-pair cables. The direction indicated by the arrow is the moving direction of the wire C and the cable.

[0074] image 3 A schematic structural view of the pay-off system 20 is shown, the pay-off system 20 includes: a pay-off device 21, and the pay-off device 21 further includes:

[0075] Wire roller 211, which can be used for winding the two exposed wires C;

Embodiment 2

[0114] Such as Figure 11 As shown, the difference between this embodiment and the first embodiment is only that the motor driving the take-up roller 311 to rotate may be a servo motor 312a.

[0115] When the motor that drives the take-up roller 31 to rotate is a servo motor 312a, a speed sensor 314 is also provided between the take-up roller 311 and the guide wheel set 322; and a control system connected to the speed sensor 314 ; The control system is used to calculate the conveying speed of the twisted-pair cable according to the moving distance of the twisted-pair cable detected by the speed sensor in unit time, and adjust the conveying speed according to the conveying speed The torque and rotational speed of the servo motor 312a, preferably, the speed sensor 314 can be a photoelectric pulse generator.

[0116] In summary, in the equipment and method for fixing twisted-pair cable lay length of the present invention, it adopts extruder to extrude two exposed wires, so that ...

Abstract

The invention discloses a device and method for fixing the stranding pitch of a twisted-pair cable. The device comprises a pay-off system, an extruding machine and a take-up system, wherein the pay-off system is used for conveying two bare wires; the extruding machine is used for performing extrusion molding on the bare wires conveyed by the pay-off system so as to enable the wires to have sheathes respectively, wherein the sheathes are mutually connected into a one-piece sheath so as to form an inseparable cable; and the take-up system is used for stranding the cable according to a predetermined stranding pitch so as to form a twisted-pair cable and winding the twisted-pair cable. According to the invention, the device adopts the extruding machine to perform extrusion molding on the two bare wires so as to enable the wires to have sheathes respectively, the sheathes are connected into the one-piece sheath, the wires are turned into an inseparable cable, the cable is further stranded according to the predetermined stranding pitch so as to form the twisted-pair cable, so that the stranding pitch of the twisted-pair cable is ensured to be unchanged in the using process. In addition,the two wires of the twisted-pair cable are partially loosened or dislocated, and thus the quality of signal transmission is improved.

Description

technical field [0001] The invention relates to wire and cable technology, in particular to a twisted pair cable manufacturing equipment. Background technique [0002] Twisted pair cables are widely used in various electrical equipment as power, especially signal transmission components. In modern communication, sensing and control technology, electromagnetic interference in the air and lines is ubiquitous. These interferences seriously affect 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. The interference generated by the electromagnetic signal o...
