Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment manufacturing technology, and more specifically, it relates to a prefabricated control cabinet. Background Technology

[0002] In the electrical and automation industry, control cabinets are the core carriers of equipment operation. They require the installation of cable trays, guide rails, and various terminal blocks to achieve the orderly arrangement of electrical components and the connection of wiring. The traditional delivery mode for control cabinets is "semi-finished cabinet + on-site assembly": after the main cabinet is delivered, the construction personnel need to process the mounting plates on-site (such as drilling or punching holes), and cut the length of the cable trays and guide rails separately before assembling and fixing them one by one.

[0003] This traditional method has significant drawbacks: 1. Low machining accuracy: Manual drilling on site can easily lead to deviations in the hole positions of the mounting plate, affecting the assembly stability of electrical components; 2. Cumbersome and inefficient process: The cable trays and guide rails need to be cut piecemeal and installed section by section, which takes a long time and the wiring is messy and disorganized, increasing the difficulty of later maintenance. 3. Numerous safety hazards: burrs and sharp edges produced during on-site processing can easily damage the cable insulation layer and may even injure operators; 4. Poor adaptability: Different projects require repeated customization of opening and cutting schemes, resulting in high material waste.

[0004] Therefore, developing an integrated, prefabricated, and prefabricated control cabinet to solve the pain points of on-site processing has become a technological breakthrough direction urgently needed by the industry. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a prefabricated control cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated control cabinet, comprising a cabinet body, an internally fixedly connected mounting plate, and a plurality of precision-machined holes on the surface of the mounting plate; the surface of the mounting plate is provided with wire grooves, guide rails, and terminals that match the precision-machined holes, the wire grooves, guide rails, and terminals being prefabricated to a specified length and having fixing holes on their surfaces that match the precision-machined holes; the wire grooves, guide rails, and terminals are assembled to the mounting plate through the precision-machined holes on the surface of the mounting plate, and then fixedly mounted to a designated position on the cabinet body through the fixing holes, forming a prefabricated set structure.

[0007] Preferably, the precision-machined holes of the mounting plate include: a first type of hole for fixing the wire groove, a second type of hole for fixing the guide rail, and a third type of hole for fixing the wiring terminal. Each type of hole is digitally verified to ensure precise matching with the mounting holes of the corresponding components.

[0008] Preferably, the lengths of the cable trays and guide rails are customized according to the internal space of the cabinet body, and the fixing holes correspond one-to-one with the precision machining holes, with a deviation of ≤0.1mm.

[0009] Preferably, the mounting plate is fixed to the back or side wall of the main body of the cabinet through the mounting plate fixing holes, forming an integrated structure.

[0010] Preferably, the cable tray is used to fix the cable, the guide rail is used to install electrical components, and the terminal block is used to standardize the wiring.

[0011] This utility model provides a prefabricated control cabinet with the following advantages: 1. No on-site processing: The mounting plate holes are automatically processed by CNC machine tools, generating no debris and avoiding damage to cables or personnel from burrs / flashes. 2. Optimization of construction period and cost: Eliminates the on-site cutting and installation steps of cable trays and guide rails, reducing labor costs and material waste; 3. Precise and stable installation: The mounting holes of the components and the mounting holes of the wire trough guide rails are matched to ensure that the installation positions of the wire troughs and guide rails are consistent, with an offset of ≤0.1mm, to avoid poor circuit contact caused by assembly misalignment; 4. High quality consistency: Factory machine manufacturing has a high degree of consistency (stable hole diameter / position tolerance), and the product reliability is better than that of on-site manual operation; 5. Low operating threshold: The assembly process does not require skilled electricians; ordinary workers can complete the cabinet fixing and wiring, reducing reliance on manpower. 6. High-frequency turnover: Prefabricated complete cabinets can be stored and transported in a standardized manner, doubling the utilization rate of production and storage space and improving the efficiency of traditional scattered component storage by 50%.
