[0019] Example

[0020] To address the aforementioned technical problems, this embodiment provides a torsion-resistant signal cable, such as... Figure 1 As shown, the cable includes an outer sheath 10 and a core wire group 20 disposed within the outer sheath 10. The core wire group 20 consists of several groups of power control core wire groups 21 and signal core wire groups 22. Filler 23 is filled between the groups of signal core wire groups 22. A power control core wire group 21 is disposed between every two signal core wire groups 22. A first protective layer 30 covers the outer periphery of the core wire group 20 and the inner side of the outer sheath 10. The cable is constructed by the core wire group consisting of the power control core wire group 21 and the signal core wire group 22. Group 20, with filler 23 filling between core wire groups 20, and a power control core wire group 21 set between every two signal core wire groups 22, so that the core wire group 20 can ensure the roundness and extensibility of the product shape through the arrangement structure of core wire group 20 and filler 23. Furthermore, by covering the core wire group 20 with a first protective layer 30, the inner conductor of the core wire group 20 is effectively protected and the twisted core structure is stabilized, which greatly improves the torsional life of the cable and ensures the stability of the dispensing machine during use.

[0021] Specifically, the control core wire group 21 includes a first insulation layer 211, and a power control core 212 is provided inside the first insulation layer 211. By providing the power control core 212, the conductor of the power control core is made of ultra-fine tin-plated copper, which can effectively prevent the conductor from oxidizing and corroding, and has low resistance and good conductivity. Furthermore, by covering the power control core 212 with the first insulation layer 211, current can be effectively prevented from leaking from the conductor to the outside, thus preventing short circuits and electric shock risks.

[0022] Furthermore, the first insulation layer 211 is made of PP material, which has good mechanical properties, thus effectively extending the service life of the cable.

[0023] In the above scheme, the signal core wire group 22 comprises a second protective layer 221 and a pair of twisted signal wire core 222 arranged in the second protective layer 221, and the pair of twisted signal wire core 222 is further covered by a second insulating layer 223. By arranging the pair of twisted signal wire core 222, the pair of twisted signal wire core 222 adopts an extremely thin and soft concentric twisted conductor, so that the conductor wear resistance and flexibility can be improved. By further covering the pair of twisted signal wire core 222 with the second insulating layer 223, the wire core conductor can effectively shield external electromagnetic interference, and the normal operation of the equipment can be ensured. By further covering the second insulating layer 223 with the second protective layer 221, the pair of twisted core structure and the second insulating layer 223 can be effectively protected, and the pair of twisted core structure can be effectively stabilized.

[0024] As a preferred embodiment, the second insulating layer 223 is made of FEP material. The FEP material has high mechanical strength and low dielectric constant, so that the cable can maintain stable performance in a wide temperature and frequency range during use.

[0025] Specifically, the first protective layer 30 is composed of a first aluminum foil layer 301, a first braided layer 302 and a first PTFE tape layer 303. By adopting the double-layer shielding of the first aluminum foil layer 301 and the first braided layer 302, the interference of electromagnetic radiation on electronic equipment can be effectively reduced. By further wrapping the first aluminum foil layer 301 and the first braided layer 302 with the first PTFE tape layer 303, the anti-twist performance of the cable can be effectively improved.

[0026] Further, the second protective layer 221 is composed of a second braided layer 2211, a second PTFE tape layer 2212 and a first inner coating layer 2213. The second braided layer 2211 is composed of 0.08mm single-silk tinned copper wire braiding, so that the conductivity and softness of the cable can be effectively improved. By further wrapping the second braided layer 2211 with the second PTFE tape layer 2212 and the first inner coating layer 2213, the pair of twisted core structure can be effectively protected.

[0027] As a preferred embodiment, the diameter of the power control wire core 212 is 0.05mm.

[0028] As a preferred embodiment, the diameter of the pair of twisted signal wire core 222 is 0.08mm.

[0029] In the above scheme, the cable outer coating 10 is made of PVC material. The PVC material has the characteristics of wear resistance, low temperature resistance and high softness, so that the cable can be effectively protected from physical and mechanical damage from the outside, and the integrity of the cable can be protected.

[0030] In summary, in one or more embodiments of the present application, the cable sheath and the core wire group arranged in the cable sheath are provided, the core wire group is composed of a plurality of power control core wire groups and signal core wire groups, the filler is filled between the plurality of signal core wire groups, the power control core wire group is arranged between every two signal core wire groups, and the first protective layer is coated on the outer periphery of the core wire group and inside the cable sheath. By arranging the core wire group composed of the power control core wire group and the signal core wire group, filling the filler between the core wire groups, and arranging the power control core wire group between every two signal core wire groups, the core wire group can ensure the product shape to be round and the extensibility through the arrangement structure of the core wire group and the filler. By coating the first protective layer on the outer periphery of the core wire group, the conductor in the core wire group is effectively protected and the twisted core structure is stable, the torsional life of the cable is greatly improved, and the stability of the dispensing machine in use is ensured.
