Description

Technical Field

[0001] The utility model relates to a snap-on release of a circuit breaker, belonging to the technical field of circuit breakers. Background Art

[0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breakers are also called automatic switches. The commonly known as "air switches" also refer to low-voltage circuit breakers. They are an electrical appliance that has both manual switching functions and can automatically perform loss of pressure, undervoltage, overload and short-circuit protection. Circuit breakers are usually equipped with short-circuit protection mechanisms, also known as snap-type electromagnetic releases. When the current passing through the circuit breaker increases to a certain value, the electromagnetic release causes the circuit breaker to trip quickly, thereby achieving the function of circuit protection.

[0003] The publication number of the comparative patent document is: "The circuit breaker release of CN219696368U includes a circuit breaker body, a release body is slidably connected to the right side of the circuit breaker body, a slider is slidably connected to the front side of the circuit breaker body, blocks are slidably connected to the left and right sides of the slider, a moving rod is fixedly connected to one side of the block, and the moving rod is slidably connected to the inside of the slider."

[0004] The above patent still has the following problems in actual use: although the patent can be used for daily circuit protection operations, in actual use, the circuit breaker and the release are fastened and installed by a fixed clip. Although the L-shaped clip can be easily assembled during installation, it is difficult to deform during disassembly, resulting in the clip breaking, which makes the release installation less convenient. In addition, the connected wires of the circuit breaker and the release are only laid on top of them, which is not convenient to classify and arrange them, making the connected wires complicated, and the arrangement of the release line is not beautiful enough.
