Novel electric connection structure of adapter coupling box of cloth paving machine

The invention belongs to the technical field of cloth paving machines and particularly relates to a novel electric connection structure of an adapter coupling box of the cloth paving machine. The novel electric connection structure comprises a relay, a fuse, a rectifying bridge and a silicon controlled rectifier, wherein pins of the relay, the fuse, the rectifying bridge and the silicon controlled rectifier are inserted at corresponding positions of the front face of a PCB (Printed Circuit Board) and are fixed by soldering tin; a plugging head for plugging a signal wire of a power supply device is arranged at the edge of the front face of the PCB; the relay, the fuse, the rectifying bridge, the silicon controlled rectifier and each pin of the plugging head are connected with a relative control circuit of the cloth paving machine in a manner of distributing a plurality of layers of wires in the PCB, so as to from a complete adapter coupling box circuit board; an aluminum plate used for dissipating heat is fixedly arranged on the back face of the PCB; the PCB is mounted on a shell of the cloth paving machine; and the aluminum plate is clung to the shell of the cloth paving machine. The novel electric connection structure of the adapter coupling box of the cloth paving machine has the advantages that the problems that previous pin wires are not reliably welded, the quantity of electric wires is more, and the layout of the electric wires is disordered and the like are solved; and the PCB is mounted on the shell of the cloth paving machine so that the aluminum plate is clung to the shell of the cloth paving machine to carry out heat dissipation and the heat dissipation cost is reduced.
