Description

Technical Field

[0001] This utility model relates to an industrial control device, and more specifically, to a circuit board structure and a PLC touch screen all-in-one machine. Background Technology

[0002] PLC touch screen all-in-one machine, also known as PLC touch screen all-in-one machine, industrial control touch screen all-in-one machine, PLC all-in-one machine, etc., is a highly integrated industrial control device that integrates a touch screen, PLC and input / output terminals. It uses a programmable memory to store instructions for performing logical operations, sequential control, timing, counting and arithmetic operations. It controls various types of mechanical equipment or production processes through digital or analog input and output. It has the advantages of user-friendly human-machine interaction, strong logic processing capability, good stability and durability.

[0003] Common components of PLC touch screen all-in-one machines can be found in "Housing Structure and PLC Controller" published in Chinese Patent Publication No. CN218499391U and "A Novel PLC Touch Screen Control All-in-One Machine" published in Chinese Patent Publication No. CN112492781A. They are mainly composed of a front frame, a rear cover, a touch LCD screen, a PLC board, an integrated circuit board, and input / output terminals. All components are integrated and installed in a housing consisting of a front frame and a rear cover.

[0004] As the functional requirements of PLC touch screen all-in-one machines increase and users demand more customization, the number of functional modules that need to be connected to their circuit boards is also growing. Due to the size limitations of the circuit boards, a single circuit board can no longer meet the requirements. Stacking multiple circuit boards is a feasible technical solution. Communication connections need to be established between multiple circuit boards, so the structure of the circuit boards needs to be improved to facilitate the wiring connections between the circuit boards and the integration of different functional modules.

[0005] In addition to the input and output terminals integrated on the circuit board, many functions require communication connections using interfaces such as USB-A and USB-C. However, the orientation of the USB-A and USB-C interfaces of the PLC touch screen all-in-one machine varies depending on the installation and usage scenario. The interfaces of the existing PLC touch screen all-in-one machines are either located on the back or on the side. When developing products with different interface orientations, it is often necessary to redesign the circuit board. This repetitive development work leads to a longer product development cycle and increased costs. Summary of the Invention

In addition, its USB female connector welding port has vertical and horizontal mounting holes connected in parallel. The corresponding vertical or horizontal mounting holes can be selected on the same circuit board according to the orientation of the USB female connector, which meets the installation needs of USB female connectors with different orientations and reduces the cost of repeated development.
