Due to its high control precision, servo motors are widely used in equipment with relatively high requirements for process precision, processing efficiency, and working reliability, such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, and automated production lines. In a servo motor, a connecting cable is generally used to connect the control board and the power board connector. Since the servo motor will generate certain vibrations during operation, the current connecting cable cannot clamp and route the wire harness, resulting in loosening at the joint of the connecting cable after long-term operation. Therefore, a connecting cable for servo motor control is needed.
