Description

Technical Field

[0001] The utility model relates to the technical field of cables, and in particular to a wear-resistant and corrosion-resistant signal line used for moving parts. Background Art

[0002] There are a large number of moving parts in automated production equipment, which are connected to the control unit through signal lines and controlled by the control unit to perform corresponding actions. During production, some signal lines will translate or bend with the moving parts, and frequently rub against the bearings or guide positioning parts. In addition, the signal lines may also be corroded by the lubrication system of the moving parts. These factors cause the cable surface to be easily worn or corroded, which in turn causes the signal line to break. It is not only easily affected by external signal interference, affecting the stability of the cable transmission signal, but also has the safety hazard of leakage. On the other hand, since the cable needs to translate or bend frequently, cables with better flexibility are generally selected as signal cables, but the inner core of the cable will still frequently rub against the inner wall of the outer sheath, resulting in core wire wear, which in turn affects the transmission of the signal.

[0024] Further, such as Figure 4 As shown, each core wire 1 is provided with a metal core 3, an insulating layer 4 and a shielding layer 5 in sequence from the inside to the outside.
