Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to an electrical control cabinet connector positioning component. Background Technology

[0002] An electrical control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. It typically contains relays, circuit breakers, terminal blocks, switching power supplies, and wiring harnesses for connecting various components.

[0003] Generally, electrical control cabinets use either copper busbars or flexible wire harnesses for connections. Copper busbars are inherently more rigid than flexible wire harnesses, and although they require customization based on the internal component layout, they offer better stability after installation. Flexible wire harnesses, however, are different. When connecting circuit breakers and terminals with screws, the harness connectors rely solely on the screws for fixing, leaving the harness itself loose. This not only affects the aesthetics of the control cabinet but also creates play at the connectors, posing a risk of poor contact. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide an electrical control cabinet connector positioning component.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0026] Please see Figure 1-9 This utility model provides a technical solution: an electrical control cabinet connector positioning assembly, including a cabinet body 1, a cabinet door 2 on the front side of the cabinet body 1, the cabinet door 2 being hinged to the front side of the cabinet body 1, a row of circuit breakers 3 and a set of wiring terminals 4 being installed on the front of the inner cavity of the cabinet body 1, a first wire harness 6 being provided on the top of the circuit breaker 3, a relay 5 being installed at the bottom of the inner cavity of the cabinet body 1, and several second wire harnesses 7 being connected between the circuit breaker 3 and the wiring terminals 4;

[0027] A wire harness connector positioning mechanism is provided between the circuit breaker 3 and the terminal block 4. The wire harness connector positioning mechanism includes a mounting plate 8. Two screws 9 are inserted into the front side of the mounting plate 8. The mounting plate 8 is installed inside the cabinet 1 by the screws 9. Several connecting blocks 10 are fixedly connected to the front side of the mounting plate 8. A fixing plate 11 is fixedly connected to the front side of the connecting blocks 10. A movable plate 12 is provided on the front side of the fixing plate 11. The cross-section of the fixing plate 11 and the movable plate 12 is arc-shaped. Buffer pads 13 are fixedly connected to the inner sides of the fixing plate 11 and the movable plate 12. A toggle block 14 is fixedly connected to the front side of the movable plate 12.

[0028] A first connecting plate 15 is fixedly connected to the left side of the movable plate 12. A first fixing block 16 is provided at the bottom of the first connecting plate 15 near the rear side. The first fixing block 16 is fixedly connected to the left side wall of the connecting block 10. A limiting hole 18 is provided on the first fixing block 16. A limiting rod 17 is movably inserted through the inner cavity of the limiting hole 18. The limiting rod 17 is fixedly connected to the bottom of the first connecting plate 15. The limiting rod 17 matches the limiting hole 18. Two second connecting plates 19 are fixedly connected to the right side of the movable plate 12. A second fixing block 20 is provided between the two second connecting plates 19. The second fixing block 20 is fixedly connected to the right side wall of the connecting block 10. A through hole 23 is provided on the second fixing block 20. A connecting rod 22 is movably inserted through the inner cavity of the through hole 23. A spring 21 is movably sleeved on the outer edge of the connecting rod 22 near the bottom end. The two ends of the connecting rod 22 are fixedly connected to the two second connecting plates 19 respectively. The top of the second fixing block 20 is in contact with the adjacent second connecting plate 19.

[0029] Working Principle: This utility model discloses a positioning assembly for an electrical control cabinet connector. During use, the movable plate 12 is pushed upward by the lever 14. The movable plate 12 drives the first connecting plate 15 and the second connecting plate 19 to move upward. The first connecting plate 15 drives the limiting rod 17 to move upward, and the second connecting plate 19 drives the connecting rod 22 to move upward. The connecting rod 22 moves within the cavity of the through hole 23, while the spring 21 is compressed. After the limiting rod 17 moves upward away from the limiting hole 18, the movable plate 12 is flipped. The movable plate 12 flips around the connecting rod 22 to move away from the fixed plate 11. Then, the second wire harness 7 is placed in front of the fixed plate 11, and the two ends of the second wire harness 7 are connected to the wiring ports of the circuit breaker 3 and the terminal 4 with screws. Then, the lever 14 is pushed upward. Movable plate 12 is moved and flipped to the front of fixed plate 11. At this time, limit rod 17 is directly above limit hole 18. Then, the upward force on movable plate 12 is released, and movable plate 12 moves downward under the action of spring 21. Movable plate 12 drives limit rod 17 through limit hole 18 through first connecting plate 15, thereby fixing movable plate 12 to the front of fixed plate 11. Movable plate 12 and fixed plate 11 fix the second wire harness 7, thereby preventing the second wire harness 7 from shaking and thus preventing the second wire harness 7 from detaching from circuit breaker 3 and terminal 4. This makes the connection between the second wire harness 7 and circuit breaker and terminal stable, thereby realizing the effective positioning of the connector position inside the electrical control cabinet and ensuring the firmness of the connection between electrical components.

[0030] When it is necessary to replace one of the second wire harnesses 7, simply push the movable plate 12 on the front side of the second wire harness 7 upward, and then flip the movable plate 12 so that the movable plate 12 flips to the fixed plate 11, thereby releasing the second wire harness 7 from its restraints and disassembling the second wire harness 7. The operation is simple and convenient.
