Slots 7 are provided at one end of the fixing plates 6, pressing plates are provided in the slots 7, the other ends of the pressing plates all extend to the end faces of the adjacent substrates 1, and are all in contact with the end faces of the adjacent substrates 1.

[0020] In this embodiment, a plurality of positioning grooves are recessed on one side of each substrate 1, a plurality of positioning parts are protruded on the other side of each substrate 1, the positioning parts on the substrates 1 are all inserted into the positioning grooves of the adjacent substrates 1, the cross sections of the positioning parts and the positioning grooves are both trapezoidal structures, one end of each positioning part is in contact with the bottom surface of the corresponding positioning groove, and the other end of each positioning part is flush with the end face of the substrate 1.

[0021] In this embodiment, the locking components all include bearings and bolts 8. The bearings are all installed in the through holes 11, the bolts 8 are all installed in the inner rings of the bearings, screw holes are provided on the inner wall surfaces of the wiring grooves 4 opposite to the inner rings of the bearings, one ends of the bolts 8 are all threadedly connected to the screw holes, and the conductive plates can be quickly installed and disassembled by means of threaded connection, which increases the convenience of operation.

[0022] In this embodiment, the fixing plates 6 and the pressing plates are all made of metal materials, insulating layers 10 are installed at the exposed ends of the pressing plates, one side surfaces of the insulating layers 10 are all in contact with the fixing plates 6 on the adjacent substrates 1, and the insulating layers are made of insulating plastic materials, so that they can abut against the adjacent fixing plates, which increases the stability of the pressing plates and avoids loosening.
