The invention discloses a wiring connecting device for industrial production and assembly of a circuit board, comprising a box body and a clamping block, wherein a fixing rod is welded along a horizontal direction inside the box body, and a clamping block is welded at a vertical center of the fixing rod. In this invention, the device may be configured to press a button block, so that that clam block is driven to move upward, A conductive wire can be placed into two semicircular clips, so that that conductive line contact each other, realize wiring, Convenient connection of conductive wires, Notools required, easy to use, the semicircular clip block of the device is fixed with a conductive block, The inner side of the conductive block is provided with a bump, so that the conductive wire can be fixed, the connection is stable, no looseness occurs, the safety is improved, and the device is convenient to be replaced and repaired. The device can be used for wiring a single line, and the whole device does not need to be disassembled when a single line is connected.
