Description

Technical Field

[0001] This utility model belongs to the field of circuit breaker wiring technology, specifically an intelligent circuit breaker wiring device and its circuit breaker. Background Technology

[0002] Intelligent circuit breakers integrate microprocessors, sensors, communication modules, and other components. Sensors can monitor parameters such as current, voltage, power, and temperature in the circuit in real time and transmit this data to the microprocessor for analysis and processing. Currently, the technology is mature and can be networked for control. An intelligent circuit breaker is 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. Terminal blocks are used to facilitate the connection of wires. They are actually a metal plate sealed in insulating plastic with holes at both ends for inserting wires and screws for tightening or loosening. During circuit installation and wiring, terminal blocks often serve as a bridge connecting circuit breakers to other electrical equipment or wires.

[0003] Utility model patent application publication number 202420009895.4 discloses a wiring device and circuit breaker for a circuit breaker, including a base and a cover. Independent wiring chambers are provided between the base and the cover. Openings are formed on both sides of each wiring chamber. Conductive components are connected within the wiring chambers, and a transfer platform is provided within each chamber. An external connection channel is provided on the base directly opposite the wiring chambers. Positioning holes are provided on the inner wall of the external connection channel. The conductive components are fixed to the base by fasteners passing through the positioning holes and the conductive components themselves. One end of the conductive component is connected to the transfer platform, and the other end extends to the outside of the external connection channel. When connecting the circuit breaker externally, a closed busbar connection structure is formed, eliminating the need to consider the size of the connecting copper busbars and the creepage distance requirements between them. This meets the wiring needs of various circuit breakers, improving versatility. Furthermore, the wiring device allows for quick and convenient connection, reducing the workload of actual circuit breaker external wiring.

[0004] As can be seen from the above patent, there is an intelligent circuit breaker wiring device and its circuit breaker. However, it still has shortcomings in actual use. The most obvious one is that the wiring device on the current circuit breaker usually uses bolts and clamps to connect the lines. After the lines are connected, the bolts and clamps are usually directly exposed to the environment. Although there is a protective shell during use, before the protective shell is installed, the exposed bolts and clamps are easily affected by external impacts, which can cause deformation or loosening, affecting the connection stability and reducing the efficiency of the wiring device. Therefore, we propose an intelligent circuit breaker wiring device and its circuit breaker. Utility Model Content

[0016] In the scheme of this application:

[0017] By setting mounting slots on the terminals, the rotating shaft and L-shaped baffle are supported by the mounting slots. The longitudinal movable frame drives the movable rod and plastic toothed plate to move longitudinally. Since the plastic toothed plates are respectively engaged on the side of the two sets of plastic gears that are close to each other, the plastic toothed plates can drive the two sets of plastic gears to rotate relative to each other when they move. The plastic gears drive the connecting rod and rotating shaft to rotate, and the rotating shaft drives the L-shaped baffle to rotate and rotate the L-shaped baffle into the wiring slot. This can protect the bolts and pressure plates, reduce the impact of external forces on the bolts and pressure plates, and prevent deformation or loosening. This ensures the stability of the connection and improves the efficiency of the wiring device.

[0018] By setting two sets of movable plates inside the movable frame, and a spring between the two sets of movable plates, the spring applies an elastic force to the movable plates, and the movable plates drive the limit rod to move into the positioning hole on the positioning block, thereby limiting the movable frame and locking it after movement, which is convenient to use.
