The utility model discloses a drag chain cable of a servo power line, which comprises a support bar on which a limited piece is arranged, a flexible wire is respectively arranged between the limited pieces, an insulating layer is wrapped on the limited piece, an outer protective layer is wrapped on the insulating layer, and a step is arranged on the outer protective layer. The four flexible wires can be separated by the ring-shaped uniformly set stopper. As the front and rear adjacent stopper have a certain distance, the bending space is reserved for the center of the whole cable. During the bending process of the whole towline cable, the bending part will be connected by the step due to the setting of the step, and the gap between the step and the front and rear adjacent stopper can leave the bending space for the outer protective layer At the same time, the thickness of the outer protective layer at the position where the steps are set is small, and the flexibility at the bend is better, so as to reduce the damage to the soft wire against the pressure, protect the soft wire, and solve the problem that the outer protective layer and the insulating layer at the bend have a great impact on the soft wire against the pressure, and cause great damage to the soft wire.

伺服动力线拖链线缆
本技术涉及伺服动力线拖链线缆。
技术介绍
在设备单元需要来回移动的场合,为了防止电缆纠缠、磨损、拉脱和散乱,常把电缆放入电缆拖链中,对电缆形成保护,并且电缆还能随拖链实现来回移动,这种可以跟随拖链进行来回移动而不易磨损的高柔性专用电缆便叫拖链电缆,通常也可称之拖曳电缆,坦克链电缆。现有的拖链线缆整体采用绝缘层包裹四个软线,并在绝缘层外部包裹一层外保护层,绝缘层多为牛皮纸,而外保护层采用软质聚氯乙烯制成,因而整体拖链线缆可配合拖链弯曲,存在的不足之处有:外保护层多紧密包裹内部软线,整体线缆没有为其自身设置弯曲空间,弯曲处外保护层和绝缘层对软线抵压力很大,对软线伤害很大。
技术实现思路
本技术的目的在于提供伺服动力线拖链线缆,以解决上述
技术介绍
中提出弯曲处外保护层和绝缘层对软线抵压力很大,对软线伤害很大的问题。为实现上述目的,本技术提供如下技术方案:伺服动力线拖链线缆,包括支撑筋,所述支撑筋上布设有限位片,所述限位片之间分别装设有软线,所述限位片上包裹有绝缘层,所述绝缘层上包裹有外保护层,所述外保护层上布设有台阶。优选的,所述支撑筋为圆形结构。优选的,所述限位片为方片结构,前后相邻的限位片之间的距离不大于三厘米。优选的,所述限位片的截面厚度不大于两毫米。优选的,所述台阶为圆环形凹槽结构。与现有技术相比,本技术的有益效果是:通过环形均匀设置的限位片,可将四个软线分隔开,由于前后相邻的限位片带有一定的距离,为整体线缆中心留出弯折空间, ...
