Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a PLC cabinet that is convenient for wiring. Background Art

[0002] In the field of industrial automation control, a PLC cabinet is a control cabinet specially used to install programmable logic controllers (PLCs) and related electrical equipment. A PLC cabinet is usually an integrated device consisting of a metal cabinet, mounting plate, power supply, input and output modules, communication modules, controllers, etc. It provides a stable, safe, easy-to-operate and maintain working environment for the PLC system. The cabinet structure is reasonably designed to facilitate the installation and disassembly of equipment, with clear identification and wiring, so that operators can quickly and accurately find the required equipment and lines, and provide convenient maintenance channels and operating space to facilitate equipment inspection and maintenance.

[0003] Traditional PLC cabinets have obvious deficiencies in cabling design. Generally speaking, in order to achieve the connection between internal and external devices, traditional PLC cabinets will set wire holes on the cabinet body so that cables can pass through these wire holes for connection;

[0004] However, the position of the wire holes on the traditional PLC cabinet is fixed, which brings a problem. In actual applications, due to the different requirements of the PLC cabinet in different application scenarios, the equipment installed inside will also be different, and the difference in equipment will directly lead to changes in the wiring direction. In this case, the wire holes in the fixed position often cannot adapt well to different wiring requirements. Therefore, in the later application process, in order to meet the actual wiring requirements, it is often necessary to open additional wiring holes. Such operations not only increase the complexity and tediousness of the work, but may also have a certain impact on the overall structure and performance of the PLC cabinet. In addition, when the line needs to be adjusted or expanded, the existing PLC cabinet is often difficult to meet the needs, which brings great difficulties to maintenance and upgrades.
