[0002] Flexible connecting wires are used to connect circuit breakers and circuits. They are mainly used to transmit current and provide power distribution. They guide current from the circuit breaker to the circuit or equipment that needs power supply. The flexible connecting wires are connected between the input and output ends of the circuit breaker to guide and transmit the electrical energy in the circuit.

[0003] However, it still has the following disadvantages in actual use:

After bundling, the single wire consists of more than 1,000 strands, and the single wire does not jump strands and the total number of single wires is not less than 3. The current guide production is not only higher than the national standard requirements, but also has a complex process structure. Utility Model Content
