The embodiment of the utility model provides a drag chain cable structure for transmitting digital signals, which comprises a control cable unit and a signal cable unit, the control cable unit and the signal cable unit are arranged in a total braid layer in parallel, the axis directions of the control cable unit and the signal cable unit are parallel, and the total braid layer is covered with a total sheath. According to the embodiment of the utility model, the original cable structure is changed into the flat structure, so that the signal cable is prevented from being extruded by the control cable in the reciprocating motion process, the signal transmission quality is ensured, the mechanical performance of the cable is improved, the drag chain test is increased from 5 million times to more than 10 million times, and the service life of the cable is prolonged. 本申请实施例提供了一种传输数字信号的拖链电缆结构，包括控制电缆单元和信号电缆单元，所述控制电缆单元和信号电缆单元并列设置于总编织层内，所述控制电缆单元和信号电缆单元的轴线方向平行，所述总编织层外覆盖有总护套。本实用新型实施例通过将原有电缆结构变更为扁状结构，避免了往复运动过程中信号电缆被控制电缆挤压，
