Problems solved by technology
In the prior art, PLC is often used to realize the control function in the low-voltage electrical module. Since the existing similar products use welding technology to connect the components to each other, the wiring operation is relatively cumbersome, especially when multiple PLCs are connected in parallel, the wiring workload is large, low efficiency
The connection method of the existing peer products is a snap connection, which is inconvenient to disassemble and not convenient for daily maintenance and repair

The invention relates to a connection structure of a PLC and a relay. The connection structure comprises a box body composed of an insulating shell and a separation board; a line pressing frame is embedded in the insulating shell; the upper end of the insulating shell is provided with a relay socket; the relay socket is provided with an electric conduction shifting fork; the electric conduction shifting fork comprises a supporting arm; the supporting arm is rotationally connected onto the insulating shell through a rotation shaft; one end of the supporting arm is provided with a connection contact; and a PLC component pin clamping structure is embedded in the insulation shell. According to the connection structure of the PLC and the relay of the invention, the pins of a component can be directly clamped into positioning grooves, so that quick connection can be realized, convenience can be brought about, and time can be saved; the connecting component bayonet is arranged in the insulating shell, and an electric conduction connecting component can be in matched connection with the connecting component bayonet, so that quick connection between adjacent PLC modules can be realized, and wiring workload can be greatly reduced, and wiring efficiency can be improved; and the rotary electric conduction shifting fork is adopted, so that quick connection can be realized, and when routine maintenance of the relay is performed, or a malfunctioned relay is replaced, the relay can be taken out only with shifting the shifting fork required.
Description
technical field [0001] The invention relates to the electrical field, in particular to a wire connection device for low-voltage electrical appliances, in particular to a connection structure between a PLC and a relay. Background technique [0002] Programmable logic controller (hereinafter referred to as PLC) is widely used in industrial automation control. In the prior art, PLC is often used to realize the control function in the low-voltage electrical module. Since the existing similar products use welding technology to connect the components to each other, the wiring operation is relatively cumbersome, especially when multiple PLCs are connected in parallel, the wiring workload is large, low efficiency. The existing products of the same industry are connected by a buckle connection, which is inconvenient to disassemble and not convenient for daily maintenance and repair. Contents of the invention [0003] The purpose of the present invention is to provide a connec...
