[0002] A circuit system refers to a system used for power transmission, which requires the use of a large number of electrical components in the process of power transmission. Common electrical components include switches, power cabinets and transformers. A circuit breaker refers to a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time. When a short circuit or leakage occurs in the circuit, the circuit breaker can quickly disconnect the circuit to avoid greater harm caused by the operation of the circuit. Circuit breakers generally connect wires to the connectors of the circuit breaker through positioning bolts, which takes a long time, especially in construction sites where circuit changes are frequent.

[0003] When used in electrical fields such as construction sites, the speed of disconnecting and connecting multiple circuit breakers will be seriously affected. It is not only dangerous but also inconvenient to perform quick wiring operations. Since the electrical connection wires are not convenient to fix, it is more troublesome to connect the electrical connection wires to the circuit breakers, which often causes the connection points of the electrical connection wires to be exposed to the external environment.

In this way, mutual interference between cables can be avoided, and the stability and reliability of electrical connection can be ensured.

[0023] The fixing fork 602 forms a connection structure with the connection port 604 through the first locking valve 603. The connection structure is provided with two groups to reduce the area of ​​the connection exposed to the outside. It can be directly connected to reduce the risk of connection. It only needs to insert the cable.

[0024] The left connection groove 605 and the right connection groove 606 are axially symmetrically distributed with the second locking valve 607.

The sub-valve 3 and the main valve 4 are used to control the switching on and off of the circuit. The sub-valve 3 is used to control different branch circuits, and the main valve 4 controls the circuit state of the combined circuit as a whole. The locking device 6 is used to ensure that the circuit breaker is firmly fixed during use to prevent loosening due to vibration or other reasons. A single circuit presses the first locking valve 603 to press the fixing fork 602 downward and lock it with the line port, so that the connection port 604 is not exposed to the outside and is locked inside. The combined circuit is connected and inserted together through the left connection groove 605 and the right connection groove 606, and then locked in the same way. After the upper connection is made, in order to ensure that the folded part of the line is not easily broken, an auxiliary device 7 is used to protect the line segment at the connection.
