Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, and in particular to a circuit breaker that is easy to wire. Background Technology

[0002] A circuit breaker is a switching device used to distribute electrical energy and protect power lines and motors. It can close, carry, and interrupt current, and can carry and interrupt current under abnormal circuit conditions for a certain period of time. When the circuit is overloaded, short-circuited, or undervoltage, the circuit breaker can automatically disconnect the circuit, thereby protecting the safety of power distribution lines and electrical equipment.

[0003] Currently, when connecting circuit breakers, bolts are used to connect the metal coil to the circuit breaker. Using bolts requires tools such as screwdrivers, which is cumbersome and the confined space restricts operation. Therefore, we propose a circuit breaker that is easy to wire to solve the above problems. Utility Model Content

A conductive plate 5 is fixedly connected to the inner bottom wall of the circuit breaker body 1. Two connecting plates 6 are fixedly connected to the inner side wall of the circuit breaker body 1. Bearings 12 are embedded in the outer surfaces of the two connecting plates 6. A connecting rod 7 is fixedly connected to the inner rings of the two bearings 12. A first sliding groove plate 8 is fixedly connected to the inner top wall of the circuit breaker body 1. A first toothed plate 9 is slidably connected to the outer surface of the first sliding groove plate 8. A second sliding groove plate 11 is fixedly connected to the inner top wall of the circuit breaker body 1. A second toothed plate 13 is slidably connected to the outer surface of the second sliding groove plate 11. A pressure plate 14 is fixedly connected to the bottom surface of the second toothed plate 13. A pressure plate 14 is fixedly connected to the outer surface of the connecting rod 7. Two gears 10 are connected, one of which meshes with the first gear plate 9, and the other gear 10 meshes with the second gear plate 13. A protective mechanism 2 is provided on the outer surface of the circuit breaker body 1. A pressing mechanism 3 is fixedly connected to the inner bottom wall of the circuit breaker body 1. A limit mechanism 4 is fixedly connected to the outer surface of the connecting rod 7. An inlet is provided on the outer surface of the circuit breaker body 1. By moving the first gear plate 9, the gear 10, the connecting rod 7 and the ratchet 404 can be driven to rotate, so that the gear 10 drives the second gear plate 13 and the pressure plate 14 to move downward. The pressure plate 14 will press the metal wire core onto the conductive plate 5, thereby completing the connection between the circuit breaker body 1 and the metal wire core. The operation is simple and convenient, and the wiring efficiency is improved.

[0023] The protective mechanism 2 includes an isolation cover 201. Two first magnetic blocks 202 are fixedly connected to the outer surface of the isolation cover 201.

The pressing block 303 is pushed towards the pressing soft seat 305 by the first elastic element 302, which can fix the line between the pressing block 303 and the pressing soft seat 305, making the line connection more stable.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, remove the rubber protective sleeve outside the line, remove the isolation cover 201, pull the first pull ring 304 upward to move the metal wire core of the line onto the conductive plate 5, move the first toothed plate 9 to drive the gear 10, connecting rod 7 and ratchet 404 to rotate, the gear 10 drives the second toothed plate 13 to move downward, so that the pressure plate 14 presses the metal wire core onto the conductive plate 5, release the first pull ring 304, under the action of the first elastic element 302, the pressing block 303 presses the rubber protective sleeve of the line onto the pressing soft seat 305, the limiting plate 401 will restrict the rotation of the ratchet 404 to prevent the second toothed plate 13 and the pressure plate 14 from moving upward, and install the isolation cover 201 on the circuit breaker body 1.
