Description

Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker housing. Background Technology

[0002] In power systems, circuit breakers are key devices for ensuring the safe operation of circuits, and their performance and reliability are of paramount importance. The circuit breaker housing is an important component that protects the internal circuit components, providing not only physical support for the internal components but also effectively resisting interference from external environmental factors.

[0003] Traditional circuit breaker housings have wiring ports on the side for circuit connections. However, in practical use, when these ports are not in use, the lack of effective protection leads to several drawbacks. Dust, moisture, and other impurities can easily enter the housing through the ports, adhering to the surfaces of circuit components. Long-term accumulation can cause corrosion, short circuits, and other malfunctions, affecting the normal operation of the circuit breaker and reducing its lifespan and reliability. Furthermore, small foreign objects can also enter through the ports, damaging the delicate internal circuit structure. Therefore, developing a circuit breaker housing structure that can effectively seal the wiring ports and prevent impurities from entering is of significant practical importance.

[0012] The beneficial effects of this utility model are:

[0013] 1. When the wiring port is not in use, the sealing plate mechanism can block the wiring port. The slots on the main plug plate correspond to the wiring ports. After the secondary plug plate is inserted into the plug plate slot, it can block the slots and wiring ports, effectively reducing the possibility of dust, moisture and other impurities entering the casing. This effectively avoids corrosion and short circuit problems of circuit components caused by impurities, and ensures a clean and stable operating environment for the internal circuits of the circuit breaker.

[0014] 2. The sealing plate mechanism is designed for excellent convenience and flexibility. The arc-shaped spring on the main insert plate matches the arc-shaped concave surface of the slot's inner wall, making the insertion and removal of the main insert plate smoother and ensuring easy disassembly. The lever on the secondary insert plate slides into the guide groove on the main insert plate, allowing operators to easily control the sealing and opening of the slot by moving the lever. This simple and convenient operation enhances the user experience.

[0015] 3. In addition, after wiring the connector, you can insert the secondary plug to cover the wiring hole, which can reduce the entry of dust.

[0016] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
