Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker wiring mechanism. Background Art
[0002] The world's earliest circuit breaker appeared in 1885. It was a simple structure consisting of a traditional blade and a blade holder. In 1905, air circuit breakers with free tripping devices began to appear, marking the initial development of circuit breaker technology. At the end of the 20th century, with the development and popularization of miniaturized computers, intelligent circuit breakers came into being, ushering circuit breaker technology into a new stage of development.
[0003] The development of arc extinguishing devices in circuit breakers has evolved from mechanical to electronic and now to intelligent types. Vacuum arc extinguishing devices and SF6 gas arc extinguishing devices are currently the two most commonly used types. Circuit breaker operating mechanisms have evolved from electromagnetic to spring to hydraulic mechanisms. Modern operating mechanisms require low power, high performance, high reliability, and modularity. Circuit breakers are categorized by voltage level into medium voltage, high voltage, extra-high voltage, and ultra-high voltage. Currently, the highest voltage for circuit breakers has reached 1100 kV, meeting the power system's demand for high-voltage equipment.
[0004] Circuit breakers are widely used in power systems, communications systems, and other fields. In power systems, circuit breakers protect power supplies, prevent grid failures, and maintain grid stability. In communications systems, circuit breakers protect telephone lines and network equipment from overvoltage, overcurrent, and other factors.
[0005] Existing circuit breaker wiring mechanisms connect the live wires to the circuit breaker, typically using screws to directly squeeze the live wires and the circuit breaker's conductor together. However, when the live wires are composed of multiple strands of copper wire, simply squeezing and fixing them with screws is not enough to securely secure the live wires to the circuit breaker's conductor. Utility Model Content

The bottom of the centralized clamp is provided with a connecting hole, and a terminal post is fixedly installed inside the wiring module, and the terminal post is adapted to the connecting hole.
[0008] As a further description of the above technical solution: the adjustment mechanism includes two ball screws, the thread directions of the two ball screws are opposite, the two ball screws are respectively threadedly connected to one side of the two centralized clamps, and a connecting plate is fixedly connected between the two ball screws.
[0009] As a further description of the above technical solution: the top end of the ball screw is slidably connected to a rotating rod, the top end of the rotating rod passes through the top of the wiring module and rotates with the wiring module, and the lower end of the ball screw at the bottom is rotatably connected to a telescopic column, and the telescopic column is fixedly installed inside the wiring module.
[0010] As a further description of the above technical solution: a receiving groove is provided on one side of each of the two central clamps, and the connecting piece is arranged inside the receiving groove, and the connecting piece and the receiving groove are adapted to each other.
[0011] As a further description of the above technical solution: a connecting groove is provided on the top of the central clamp, an adjusting bolt is threadedly connected to the top of the wiring module, and the bottom end of the adjusting bolt passes through the top of the wiring module and contacts the bottom of the connecting groove.
