Then, the upper wire harness 32 is closed, and finally the manual bolt 33 is tightened to ensure the stability of the upper wire harness 32 after it is closed. This utility model, through the wire harness mechanism 3, ensures the stability of the connection of the PCB board bodies 1 by fixing the two ends of the lower wire harness 31 to the two PCB board bodies 1 respectively. The upper wire harness 32 and the lower wire harness 31 are connected to form an open and close structure. The upper wire harness groove 321 and the lower wire harness groove 311 guide and clamp the interconnecting wires 2 to prevent the interconnecting wires 2 from loosening, thereby improving the reliability of the PCB board body 1.
