[0033] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0034] like Figure 1 As shown, a grounding circuit breaker of this utility model includes a circuit breaker 1. The circuit breaker 1 includes a main body 101. Anti-accidental contact mechanism 2 is provided on both sides of the main body 101. The anti-accidental contact mechanism 2 includes two mounting brackets 201. The two mounting brackets 201 are fixedly connected to both sides of the main body 101. The outer surface of the two mounting brackets 201 is provided with a sliding groove 202. A sliding rod 209 is provided in the sliding groove 202. A slider 203 is slidably connected on the sliding rod 209, and the slider 203 engages with the sliding groove 202 and slides.

[0035] The outer surfaces of the two sliders 203 are provided with screw holes 205, and the outer surface of the main body 101 is provided with a cover 206. The two sides of the cover 206 are provided with side ears 207. The two side ears 207 are fixedly connected to the sliders 203 by fixing bolts 208.

[0036] The bottom of slider 203 abuts against spring 204, and the other end of spring 204 abuts against slide groove 202. Anti-accidental contact mechanisms 2 are provided on both sides of the main body 101. Two mounting brackets 201 are fixed to both sides of the main body 101. A slide rod 209 is located in the slide groove 202 of the mounting bracket 201. Sliding slider 203 slides on the slide rod 209 and engages with the slide groove 202. The bottom of slider 203 is abutted against by spring 204. A retainer 206 is connected to slider 203 via side ears 207 and fixing bolts 208. When the circuit breaker is operating normally, retainer 206 can prevent accidental contact with operating handle 104; during operation, pushing retainer 206 causes slider 203 to slide, and after operation, spring 204 resets it, ensuring operational safety.

[0037] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The anti-accidental contact mechanism 2 is made of engineering plastic, and the cover 206 is made of transparent plastic. This material, corrosion-resistant and impact-resistant, allows the anti-accidental contact mechanism 2 to maintain stable performance in harsh working environments, extending its service life and reducing maintenance costs. The transparent plastic cover 206 allows operators to directly observe the position and status of the operating handle 104 without opening it, enabling more accurate opening and closing operations when operating the circuit breaker. This avoids operational errors caused by poor visibility and improves the overall convenience and safety of the circuit breaker.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 An operating handle 104 is located on the lower outer surface of the main body 101, and multiple fastening screws 103 are located on the upper outer surface of the main body 101. The operator can directly operate the handle 104 to perform the opening and closing actions of the circuit breaker. This design is ergonomic and convenient for manual operation. Simultaneously, the multiple fastening screws 103 on the upper outer surface of the main body 101 provide a secure connection, tightly fixing the main body 101 to other related components. This prevents components from loosening due to vibration or other reasons during circuit breaker operation, thereby ensuring the stability and reliability of the entire circuit breaker structure and guaranteeing its normal operation.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the main body 101 is provided with multiple terminals 102, the number of which matches the number of fastening screws 103. These terminals 102 are key components for connecting the circuit breaker to external circuits, enabling current transmission and signal exchange. The matching number of terminals 102 with the fastening screws 103 ensures that during installation, the screws securely fix the wires or other components connected to the terminals 102, effectively reducing problems such as increased resistance and overheating caused by poor contact, ensuring stable circuit transmission, and improving the electrical performance and safety of the circuit breaker.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4The shape of the shield 206 conforms to the outer contour of the operating handle 104 and can completely cover the movement trajectory of the operating handle 104 in the opening and closing states. This design allows the shield 206 to form a comprehensive protective barrier around the operating handle 104. Regardless of whether the operating handle 104 is in the open or closed position, or in any intermediate state during the opening and closing process, the shield 206 can effectively prevent personnel or other objects from accidentally touching the operating handle 104, avoiding unplanned operation of the circuit breaker due to accidental contact, and providing a reliable guarantee for the safe and stable operation of the circuit breaker.

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The shield 206 is detachably connected to the slider 203 via side ears 207 and can move synchronously with the slider 203 within the slide groove 202. This detachable design allows the shield 206 to be easily removed from the slider 203 for replacement or cleaning when damaged, contaminated, or requiring regular maintenance, reducing maintenance costs and difficulty. Simultaneously, the shield 206 moves synchronously with the slider 203, ensuring that it remains in a suitable protective position when the operator pushes it to operate the operating handle 104, providing continuous and effective protection for the operating handle 104 throughout the entire operation.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The extension direction of the slide groove 202 is perpendicular to the movement direction of the operating handle 104. This structural layout allows the movement direction of the cover 206 within the slide groove 202 to form a reasonable spatial relationship with the movement direction of the operating handle 104, achieving effective protection and flexible operation of the operating handle 104 within a limited space. When the operator needs to operate the operating handle 104, they can easily push the cover 206 in a direction perpendicular to the movement of the operating handle 104, causing the cover 206 to slide within the slide groove 202, exposing the operating handle 104 for operation, thus saving space and improving operational convenience.

[0043] See Figure 1 , Figure 2 , Figure 3 , Figure 4The shield 206 is detachably connected to the slider 203 via the side lug 207 and can move synchronously with the slider 203 within the slide groove 202. This detachable connection allows for easy and quick replacement of the shield 206 in case of damage or aging, reducing maintenance costs and complexity. Furthermore, the shield 206's synchronous movement within the slide groove 202 ensures that when the operator pushes the shield 206 to operate the operating handle 104, the shield 206 remains in a suitable protective position and does not lose its protective function due to movement. This ensures continuous and effective protection for the operating handle 104 throughout the entire operation, guaranteeing operator safety.

[0044] In implementation, firstly, anti-accidental contact mechanism 2 is set on both sides of the main body 101. The anti-accidental contact mechanism 2 is fixed to both sides of the main body 101 by two mounting brackets 201. There is a sliding rod 209 in the sliding groove 202 opened on the mounting bracket 201. The slider 203 is slidably connected to the sliding rod 209 and engages with the sliding groove 202 to slide. At the same time, the bottom of the slider 203 is abutted by a spring 204. When the circuit breaker is in normal state, the cover 206, with its shape conforming to the outer contour of the operating handle 104 and its ability to completely cover the movement trajectory of the operating handle 104 in the opening and closing state, effectively prevents personnel from accidentally touching the operating handle 104, avoids unplanned opening and closing of the circuit breaker due to accidental contact, and ensures stable circuit operation and equipment and personnel safety.

[0045] Secondly, side ears 207 are provided on both sides of the cover 206, which are fixedly connected to the slider 203 by fixing bolts 208. The cover 206 can move synchronously with the slider 203 in the slide groove 202. The extension direction of the slide groove 202 is perpendicular to the movement direction of the operating handle 104. When the operating handle 104 needs to be operated, the cover 206 can be pushed. The cover 206 drives the slider 203 to move along the slide groove 202, and the spring 204 is compressed. After the operation is completed, the spring 204 restores its deformation and pushes the slider 203 and the cover 206 to reset. This facilitates operation while providing continuous protection.

[0046] Furthermore, the anti-accidental touch mechanism 2 is made of engineering plastic, which has the characteristics of corrosion resistance and impact resistance. It can adapt to complex and harsh working environments, extend service life, and reduce maintenance costs. The cover 206 is made of transparent plastic, which allows operators to directly observe the position and status of the operating handle 104, thereby improving the accuracy and efficiency of operation. Moreover, the cover 206 is detachably connected to the slider 203 through the side ear 207, which facilitates installation, disassembly and maintenance when the cover 206 is damaged or needs cleaning.

[0047] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0048] 1. The anti-accidental contact mechanism is ingeniously designed. Through the cooperation of sliders, springs, etc., the cover can move and reset with the operation, effectively blocking accidental contact, avoiding unplanned opening and closing, ensuring the safety of circuit breaker operation, and solving the safety hazard problem of easy accidental contact in traditional circuit breaker operation.

[0049] 2. The materials are reasonably selected, the engineering plastics are durable, the transparent plastic cover is easy to observe, and the detachable connection makes maintenance convenient, which solves the problems of poor durability, inconvenient observation and complicated maintenance of traditional protective devices.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
