Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] Example 1:

[0032] This embodiment provides a circuit breaker that is easy to use and install, including a top cover 1 and a base 2, as well as a sliding module 3 and a fixing module 4. The sliding module 3 is installed on the base 2 and is used to slide and cooperate with the mounting bracket 5 on the distribution box in the X direction.

[0033] Fixed module 4 includes:

[0034] The clamping assembly includes a first clamping block 43 and a second clamping block 44, both of which are movable along the Z direction and mounted on the base 2 for abutting against the mounting bracket 5 on the distribution box along the Z direction.

[0035] The first control screw 41 is rotatably mounted on the base 2 and threadedly connected to the first clamping block 43;

[0036] The second control screw 42 is rotatably mounted on the base 2 and threadedly connected to the second clamping block 44.

[0037] In this technical solution, the first clamping block 43 and the second clamping block 44 are movably mounted on the base 2 along the Z-axis. By rotating the first control screw 41 and the second control screw 42, the first clamping block 43 and the second clamping block 44 are moved closer to each other or further apart, thereby realizing the installation and removal of the circuit breaker on the mounting bracket 5. A guide mechanism connected to the first clamping block 43 and the second clamping block 44 is also provided on the base 2. The guide mechanism can be a guide rod or a guide rail, which guides the movement of the first clamping block 43 and the second clamping block 44.

[0038] Furthermore, the first control screw 41 passes through the sliding module 3 and includes a first guide section 411 and a first threaded section 412. The first guide section 411 is located above the sliding module 3 along the Z direction, and the first threaded section 412 is located below the sliding module 3 along the Z direction.

[0039] Furthermore, the second control screw 42 passes through the sliding module 3 and includes a second guide section 421 and a second threaded section 422. The second guide section 421 is located below the sliding module 3 along the Z direction, and the second threaded section 422 is located above the sliding module 3 along the Z direction.

[0040] The first clamping block 43 is disposed above the sliding module 3 along the Z direction, the first guide section 411 is disposed through the first clamping block 43 along the Z direction, and the second threaded section 422 is threadedly connected to the first clamping block 43; the second clamping block 44 is disposed below the sliding module 3 along the Z direction, the second guide section 421 is disposed through the second clamping block 44 along the Z direction, and the first threaded section 412 is threadedly connected to the second clamping block 44.

[0041] With the above structural design, the movement of the first clamping block 43 and the second clamping block 44 can be guided without the need for an additional guiding mechanism, making the structure simpler and more practical.

[0042] In summary, when installing the circuit breaker in the distribution box, the installation position of the circuit breaker on the mounting frame 5 is first determined by inserting the sliding module 3 on the base 2 into the slide rail 6 of the mounting frame 5. Then, the position of the circuit breaker is adjusted along the X-axis by sliding the sliding module 3 and the slide rail 6. Next, the first clamping block 43 and the second clamping block 44 are driven to move closer to each other along the Z-axis by rotating the first control screw 41 and the second control screw 42. The first clamping block 43 and the second clamping block 44 clamp the mounting frame 5 along the Z-axis, thereby achieving a secure connection of the circuit breaker on the mounting frame 5. The operation is simple, and the installation and disassembly are convenient, making it highly practical.

[0043] Example 2:

[0044] This embodiment provides a circuit breaker that is easy to use and install. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0045] Furthermore, the sliding module 3 includes:

[0046] The mounting base 31 has a mounting groove 32 on its end face along the Y direction, and a through hole is provided on the side wall of the mounting groove 32 along the Z direction.

[0047] Roller 33 is rotatably disposed in mounting groove 32, and part of roller 33 is exposed through through hole to fixed base 31;

[0048] The portion of the roller 33 exposed on the fixed base 31 is used for rolling contact with the mounting bracket 5 on the distribution box.

[0049] In this technical solution, a rotatable roller 33 is provided on the fixed seat 31 of the sliding module 3. The roller 33 makes rolling contact with the slide rail 6 of the mounting frame 5, which makes the circuit breaker slide more smoothly on the mounting frame 5 and effectively reduces the friction force, thereby reducing wear and extending service life.

[0050] Furthermore, the sliding module 3 also includes:

[0051] A cover plate, hinged to a fixed base 31, is used to seal the opening of the mounting groove 32.

[0052] This structural design facilitates the installation and removal of the roller 33 within the fixed base 31. At the same time, the cover plate can also provide some protection against dust, thereby reducing dust accumulation in the mounting groove 32 and preventing a large amount of dust from adhering to the surface of the roller 33 and affecting its use.

[0053] Furthermore, the fixing seat 31 is integrally connected with the base 2.

[0054] Through this structural design, the fixing base 31 can be directly integrally processed with the base 2, which is convenient for production. The integral structure also enhances the connection strength between the fixing base 31 and the base 2, making the structure more stable and highly practical.

[0055] Example 3:

[0056] This embodiment provides a circuit breaker that is easy to use and install. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0057] Furthermore, the fixed module 4 also includes:

[0058] Anti-slip pads are provided on the end face of the clamping block that contacts the mounting bracket 5.

[0059] In this technical solution, several insulating rubber protrusions are provided on the surface of the anti-slip pad that is used to contact the mounting bracket 5. Through this structural design, the contact area between the clamping block and the mounting bracket 5 is increased, thereby increasing the friction during clamping and effectively improving the clamping stability.

[0060] Furthermore, the fixed module 4 also includes:

[0061] The sleeve 45 is installed on the control screw. The sleeve 45 can be made of insulating rubber. The sleeve 45 is fitted on the end of the control screw for the operator to hold. The operator can operate the control screw to rotate by holding the sleeve 45, which effectively improves the comfort of operation, avoids hand scratches, and is highly practical.

[0062] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
