[0002] Electrical control cabinet wiring is a crucial step in ensuring the safe and stable operation of electrical systems. It must follow scientific design principles, strict process standards, and standardized operating procedures. Its core objective is to achieve reliable connections between electrical components and meet the requirements of control logic, safety protection, and ease of maintenance. This includes component division, incoming and outgoing wiring methods, and connection forms. When dividing components, components with similar functions and close wiring should be integrated. For example, thermal relays and contactors should be placed close together to shorten wiring distances and facilitate heat dissipation.

[0003] Electrical control cabinet terminal blocks are key components for achieving electrical connections between equipment within the cabinet. Their core functions include providing stable wire connection points, transmitting control signals and power, and securing cables to prevent loosening. In some electrical control cabinets, the outgoing wires are connected to the relays inside the cabinet only by copper lugs, causing the weight of the outgoing wires at the bottom of the cabinet to affect the connection. Therefore, a locking structure for electrical control cabinet terminal blocks is needed to lock the outgoing terminal blocks to the cabinet base plate, preventing the weight of the outgoing wires from pulling the terminal blocks downwards, thereby improving the stability and reliability of the electrical control cabinet terminal block connections.

When terminal 19 contacts, it may cause damage to the surface of the latter, thereby improving the protection of the outgoing terminal 19. The bottom of the rotating plate 2 and the fixed plate 1 are respectively welded with ear block 12 and groove block 13. A bolt rod 14 is installed through the ear block 12 and groove block 13. The surface of the bolt rod 14 is threaded with a nut block 15. An elastic washer 16 is sleeved on the surface of the bolt rod 14. The elastic washer 16 fits in contact with the groove block 13. The setting of the elastic washer 16 increases the friction on the surface of the bolt rod 14, and avoids the bolt rod 14 from loosening due to external force vibration, thereby improving the stability of the fastening between the bolt rod 14 and the nut block 15. The bottom end of the outgoing terminal 19 passes through the control cabinet housing 18, the fixed plate 1 and the rotating plate 2 in sequence. The bottom of the rotating plate 2 is provided with an arc-shaped groove 17 that matches the groove block 13. The top of the fixed plate 1 is fixedly connected to the control cabinet housing 18. The outgoing terminal 19 is provided in the inner cavity of the control cabinet housing 18.

[0025] Example 2:

[0026] Figure 1-4This invention illustrates a locking structure for the wiring terminals of an electrical control cabinet according to an embodiment of the present invention. The structure includes a fixed plate 1; a rotating plate 2 is rotatably connected to the bottom of the fixed plate 1; a telescopic T-shaped plate 3 is welded to the surface of the fixed plate 1; a clamping plate 4 and a connecting plate 5 are welded to the surface of the telescopic T-shaped plate 3; a sliding groove 6 is provided at the bottom of the fixed plate 1; a slider 7 is slidably connected to the inner wall of the sliding groove 6; a pivot 8 is integrally formed at the bottom of the slider 7; an arc-shaped groove 9 adapted to the pivot 8 is provided at the bottom of the rotating plate 2; ear blocks 12 and groove blocks 13 are welded to the bottoms of the rotating plate 2 and the fixed plate 1, respectively; a bolt rod 14 is installed through the ear blocks 12 and the groove blocks 13; a nut block 15 is threaded onto the surface of the bolt rod 14; an arc-shaped groove 17 adapted to the groove blocks 13 is provided at the bottom of the rotating plate 2; a control cabinet housing 18 is fixedly connected to the top of the fixed plate 1; and a terminal block 19 is provided inside the control cabinet housing 18.

[0027] Working Principle: When using this utility model, the user rotates the hand-held rotating plate 2, which drives the inner wall of the arc-shaped groove 9 to move the dial shaft 8. This causes the dial shaft 8 to drive the clamping plate 4 to engage with the outgoing terminal 19 via the connecting plate 5 and the telescopic T-shaped plate 3. During this process, the sliding groove 6 and the slider 7 work together to limit the movement of the dial shaft 8, preventing it from shaking during movement and thus improving the stability of the dial shaft 8. Meanwhile, the groove block 13 moves within the inner cavity of the arc-shaped groove 17. Subsequently, the bolt rod 14 and the nut block 15 work together to lock the ear block 12 and the groove block 13, thereby fixing the positions of the fixing plate 1 and the rotating plate 2. This allows the clamping plate 4 to engage with and lock the outgoing terminal 19, achieving a lock between the wiring terminal of the cabinet and the cabinet base plate. This prevents the weight of the wiring from pulling down on the wiring terminal, thereby improving the stability and reliability of the electrical control cabinet wiring terminal connection.

[0028] In summary, the locking structure for the wiring terminals of this electrical control cabinet utilizes a rotating plate 2 to actuate the pivot 8. This pivot 8, through the connecting plate 5 and the telescopic T-plate 3, drives the clamping plate 4 to engage and clamp the outgoing terminal 19. Subsequently, the bolt rod 14 and the nut block 15 work together to lock the ear block 12 and the slot block 13, thereby fixing the positions of the fixing plate 1 and the rotating plate 2. This allows the clamping plate 4 to engage and clamp the outgoing terminal 19, achieving the goal of locking the wiring terminals of the cabinet outgoing lines to the cabinet base plate. This prevents the weight of the outgoing lines from pulling down on the wiring terminals, thereby improving the stability and reliability of the electrical control cabinet wiring terminal connections.
