Description

Wire harness structure capable of adaptively adjusting tension Technical Field The utility model relates to the technical field of wire harnesses, in particular to a wire harness structure capable of adaptively adjusting tension. Background In modern industrial equipment, automation systems and vehicles, wiring harnesses are widely used as an important component of electrical connections in various control circuits and power transmission systems. Conventional wire harness structures are typically composed of wires and connectors, and are often routed in a straight or simple manner, lacking an effective mechanism for adjusting the tension of the wire harness. When the length of the wire harness is slightly longer than the installation space, the phenomenon of loosening and sagging easily occurs, so that the wire harness is rubbed with other mechanical parts, and further the insulation layer is abraded and even the wires are broken, so that the potential safety hazard is large. In addition, when the existing wire harness structure faces complex working conditions such as environmental vibration, temperature change or mechanical displacement, dynamic adaptive tension adjustment cannot be realized, and therefore stability and reliability of electrical connection are affected. Particularly, in some occasions with high vibration or frequent movement (such as robots, rail transit equipment and the like), the problem that the wire harness is fatigued and damaged due to uneven stress is particularly remarkable, and therefore, a wire harness structure capable of adaptively adjusting tension is needed to solve the problem. Disclosure of Invention The utility model aims to provide a wire harness structure capable of adaptively adjusting tension, which has the advantages of automatically adjusting tension, preventing the wire harness from loosening and sagging and prolonging the service life, and solves the problems of abrasion, breakage and unstable connection of the traditional wire harness caused by length redundancy or environmental vibration. In order to achieve the aim, the utility model provides the technical scheme that the wire harness structure capable of adaptively adjusting tension comprises a wire and a connector, wherein the wire is provided with a tensioning mechanism; The connector is fixedly arranged at the front end and the rear end of the wire, the tensioning mechanism comprises a tensioning box, a sliding block, a spring and a pulley, two groups of damping sliding grooves which are parallel to each other are formed in the upper end face of the tensioning box, the sliding block and the spring are arranged in the damping sliding grooves and are in sliding connection with the tensioning box, the pulley is arranged on the sliding block and is in rotating connection with the sliding block, and the wire is wound on the pulley and is in sliding connection with the pulley.
