For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. It should be noted that the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0016] like Figure 1-Figure 3 The circuit breaker capable of quick connection comprises a housing 1, a connection board 2, a spring sheet 3, a push rod 4, and a flexible rib 1a.

[0017] The shell 1 is a conventional circuit breaker shell, and is provided with a plurality of protrusions or grooves for fixing components; a groove 1d is transversely provided on the shell 1; a limiting surface 1b and a limiting surface 1c are also provided on the shell 1; the limiting surface 1b is located on the left side of the limiting surface 1c; the flexible rib 1a is cantilevered and mounted on the limiting surface 1b; the flexible rib 1a is elastic.

[0018] The terminal block 2 is L-shaped, and is installed in the groove 1d on the shell 1, and the terminal block 2 can move left and right along the groove 1d; the terminal block 2 is located between the limiting surface 1b and the limiting surface 1c; the limiting surface 1b and the limiting surface 1c are used to limit the distance of the terminal block 2 moving left and right; the flexible rib 1a is used to reset the terminal block 2 after it moves to the left.
