Detailed description of the invention

Fig. 1 is a kind of anti-interference weak-current cable structural schematic diagram that the utility model first embodiment provides；

Specific embodiment

The embodiments described below are only the use of the new type a part of the embodiment, instead of all the embodiments.Base In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts There are other embodiments, fall within the protection scope of the utility model.

Refering to fig. 1, a kind of anti-interference weak-current cable that the utility model first embodiment provides a comprising signal wire Group, the signal line group include two signal wires, signal wire internal shield 7 and signal wire external screen around signal line group periphery Layer 6 is covered, the every signal wire includes signal wire core 9 and the signal line insulating layer 8 around signal wire core periphery；One is dynamic Line of force group, the power line group include two power lines, and the every power line includes power wire core 4 and around power line The power line insulating layer 3 of core periphery；One cable outer layer wraps up the signal line group and power line group, from inside to outside according to Secondary includes a cable shield 2 and a restrictive coating 1；One strengthening core 5 is filled in the signal line group and the power line group Between gap in.
