The connecting wires between the circuit board bodies 203 are stored through the storage grooves 301c on the mounting blocks 301 and the elastic buckles 303, which solves the problem that it is inconvenient to connect the layers of the multi-layer circuit board.

[0045] Specifically, the mounting block 301 is provided with multiple mounting blocks and is movably connected to the front and rear ends inside the protective shell 1. The front end face of the mounting block 301 is provided with storage slots 301c on both sides. Multiple lifting plates 302 are movably connected to the front end of the mounting block 301. The upper and lower surfaces of the lifting plates 302 are fixedly connected with elastic buckles 303.

The lifting plates 302 are used to drive the elastic buckles 303 to move up and down. The elastic buckles 303 are used to snap the connecting wires into the lifting plates 302.

[0046] Furthermore, fixing rods 301a are welded to both the upper and lower ends of the rear end face of the mounting block 301. The rear end of the fixing rod 301a passes through the sliding groove on the front and rear end faces of the protective shell 1 and extends to the outside of the protective shell 1. The rear end of the fixing rod 301a is threadedly connected to a fastening nut 301b, and multiple fastening nuts 301b are respectively attached to the front and rear end faces of the protective shell 1.

A positioning plate 302b is fixedly connected to the other outer wall of the lifting plate 302. A second threaded rod 302d is threadedly connected to the outer wall of the positioning plate 302b away from the lifting plate 302 through a U-shaped seat 302c. One end of the second threaded rod 302d is threadedly connected to the inside of one of the threaded blind holes 301e. The other end of the second threaded rod 302d is fixedly connected to a knob 302e.

[0050] The rest of the structure is the same as in Example 1.

[0051] The operation process of this embodiment is as follows: loosen the fastening nut 301b and push the mounting block 301. When the mounting block 301 moves to the designated position, tighten the fastening nut 301b. Then, rotate the second threaded rod 302d through the knob 302e, so that the second threaded rod 302d moves out of the threaded blind hole 301e and pushes the lifting plate 302. When the lifting plate 302 moves to the designated height, rotate the second threaded rod 302d again, so that the second threaded rod 302d moves into the new threaded blind hole 301e. Finally, the connecting wires are sequentially snapped into the elastic buckle 303 and the storage slot 301c, thereby realizing the storage of the connecting wires between the layers of the multilayer circuit board.
