Description

Technical Field

[0001] This utility model belongs to the technical field of integrated circuit breakers, and in particular relates to integrated primary and secondary circuit breakers. Background Technology

[0002] A primary and secondary integrated circuit breaker is an intelligent switching device that highly integrates primary equipment (high-voltage conductive circuit) and secondary equipment (measurement, protection, control and communication functions) into one unit.

[0003] Traditional integrated primary and secondary circuit breakers typically require connecting different conductors to the connecting post and measuring unit separately. The existing connection method usually uses the terminals on the conductors and bolts to lock them to the metal conductive plate, leaving them exposed to the outside environment. Over time and under the influence of different environments, this method can lead to severe corrosion of the bolts and metal conductive plate, which affects the stable output of current and also has a certain impact on the accurate use of the circuit breaker.

The connector 261 will then be connected to the metal conductive post 23, thus connecting the wire 26 to the metal conductive post 23. Then, thread the locking ring 25 on the wire 26 to the threaded ring 24, ensuring a stable connection between the connector 261 and the metal conductive post 23, improving conductivity.

The cable management mechanism 3 is located on the front and back of the base 1 and is used to organize the wires 26. The metal conductive plate 22 and the metal conductive post 23 are integrated. The connector 261 is inserted into the metal conductive post 23. The protruding ring 262 is used to limit the connector 261 during installation.

[0018] The inner ring of the locking ring 25 is threadedly connected to the outer ring of the threaded ring 24. The top of the inner side of the locking ring 25 contacts the top of the convex ring 262. When the threaded ring 24 is not connected to the wire 26, it is threadedly connected to the sealing cap 27. The sealing cap 27 is used to seal the threaded ring 24. The terminal block 21 has three connection ports.

[0019] The base 1 has two positioning blocks 14 fixedly connected to both the front and back. The cable management mechanism 3 includes a fixing plate 31 set on the outside of the base 1.
