The utility model relates to the technical field of wire harnesses, in particular to an easily-wired separable wire harness, which comprises a plurality of groups of insulating sheaths and a connecting plate, leads are arranged in the insulating sheaths, two sliding grooves are formed in the connecting plate, sliding pins are connected in the sliding grooves in a sliding manner, the tops of the sliding pins are fixedly connected with lower clamps, and the lower clamps are fixedly connected with the lower clamps. One side of each lower clamping hoop is rotationally connected with an upper clamping hoop, the upper clamping hoops are connected with the lower clamping hoops through screws, limiting grooves are formed in the positions, located on one sides of the sliding grooves, of one sides of the interiors of the connecting plates, lock pins are fixedly connected to the positions, located in the limiting grooves, of one sides of the sliding pins, and locking nuts are in threaded connection with the exteriors of the lock pins. The beneficial effects of the utility model lie in that the corresponding wires are separated and limited through the corresponding upper clamp and the lower clamp, so that the wiring process is simple and clear, line connection can be quickly and accurately completed, line connection errors are effectively avoided, the wiring efficiency is greatly improved, and the wiring time and labor cost are saved.
