[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. In thermal power plants, the generated electrical energy needs to be transported, and circuit breakers are used to control the on / off state of the energy during transportation.

[0003] The existing equipment has the following drawbacks: However, the locations of circuit breakers, wires, and connection ports will have exposed metal ports. When debris falls between two wires, it can reduce the phase-to-phase insulation and cause a short circuit, posing a certain safety hazard.

[0004] Therefore, this application proposes an anti-accidental-touch electrical circuit breaker to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-accidental contact electrical circuit breaker to solve the problem that when debris falls between two wiring terminals, it can cause a short circuit due to reduced phase-to-phase insulation, posing a certain safety hazard.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit breaker designed to prevent accidental contact, comprising:

[0007] An anti-touch mechanism is provided between two leads on the circuit breaker body to isolate the two leads;

[0008] The anti-contact mechanism includes:

[0009] A mounting bracket is provided on the circuit breaker body;

[0010] The isolation plate is adjustable and can be installed inside the mounting base;

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 This utility model provides a technical solution: an anti-accidental-touch electrical circuit breaker, comprising:

[0030] The anti-touch mechanism 4 is made entirely of insulating material and is installed between the two leads 2 on the circuit breaker body 1 to isolate the two leads 2.

[0031] The anti-touch mechanism 4 includes:

[0032] Mounting base 41 is mounted on the circuit breaker body 1;

[0033] The isolation plate 42 is height-adjustable and installed inside the mounting base 41;

[0034] The fasteners 43 are provided on both sides of the isolation plate 42 and are used to fix the isolation plate 42 to the circuit breaker body 1.

[0035] It should be noted that during operation, multiple leads 2 are installed on the terminals 3 on the circuit breaker body 1. Then, a protective mechanism 4 is installed between two leads 2. The fixing piece 43 is removed from both sides of the circuit breaker body 1, and then the isolation plate 42 is removed from the inside of the mounting base 41. The isolation plate 42 can then isolate the two leads 2, preventing debris from falling between the two leads 2 and causing a short circuit in the circuit breaker body 1. The anti-contact mechanism 4 is set between the two leads 2 of the circuit breaker body 1, which can effectively isolate the two leads 2. When the operator operates or maintains the circuit breaker, even if they accidentally touch the anti-contact mechanism, they will not directly come into contact with the live leads 2, which greatly reduces the probability of electric shock accidents and protects the life safety of the operator.

[0036] In one embodiment, the circuit breaker body 1 has a mounting groove 101 for the isolation plate 42 to move. The mounting base 41 includes a mounting ring 411 disposed inside the mounting groove 101 and an elastic member 412 disposed inside the mounting ring 411. The upper end of the mounting ring 411 is open.

[0037] This design is for reference. Figure 4 The circuit breaker body 1 has an installation groove 101 for the isolation plate 42 to move, which provides clear positioning and guidance for the installation of the isolation plate 42 and its related components. During the installation process, the installer can quickly and accurately install the mounting base 41 and the isolation plate 42 and other components onto the circuit breaker body 1 according to the position and shape of the installation groove 101, which reduces the installation time and difficulty and improves the installation efficiency. The upper end of the installation ring 411 is open, which makes it more convenient to install the elastic element 412 and the subsequent installation of the isolation plate 42.

[0038] In one embodiment, the partition plate 42 includes a partition plate 421 sleeved on the mounting ring 411, a telescopic plate 423 sleeved on the partition plate 421, and a pressing block 422 disposed at the lower end of the telescopic plate 423 and sleeved inside the mounting ring 411. The upper end of the mounting ring 411 is provided with a limiting ring for restricting the pressing block 422. The pressing block 422 is installed at the upper end of the elastic member 412. Limiting grooves 41101 for moving the partition plate 421 are provided at the corresponding positions of the partition plate 421 on both sides of the mounting ring 411.

[0039] This design is for reference. Figure 6 ,as well as Figure 7The telescopic plate 423 allows the height of the isolation plate 42 to be adjusted according to actual needs. When the spacing between the leads 2 changes, the telescopic plate 423 can extend or retract to adjust the overall height of the isolation plate 42, ensuring that the isolation plate 42 can always effectively isolate the leads 2. This flexibility allows the anti-misoperation circuit breaker to adapt to circuit breaker bodies 1 of different specifications and layouts. When it is necessary to inspect or connect the leads 2, the length of the telescopic plate 423 can be adjusted to lower the isolation plate 42 for easy operation. After the operation is completed, the isolation plate 42 can be raised again for isolation, meeting the needs of different operation stages.

[0040] In one embodiment, the fastener 43 includes connecting blocks 424 disposed on both sides of the telescopic plate 423, a fixing plate 431 disposed on the side of the connecting block 424 away from the telescopic plate 423, and fixing bolts 432 disposed on the fixing plate 431 for fixing the fixing plate 431 to the circuit breaker body 1. The upper end of the limiting groove 41101 is provided with a limiting block 4211 for limiting the connecting block 424.

[0041] This design is for reference. Figure 6 ,as well as Figure 7 Remove the fixing bolt 432 from the circuit breaker body 1, and then pull the fixing plate 431 upward, so that the connecting block 424 drives the telescopic plate 423 to be pulled out from the inside of the partition 421, isolating the two leads 2. The telescopic plate 423 and the partition 421 are in transition fit, which can maintain a stable connection when the telescopic plate 423 is pulled out from the partition 421, ensuring the stability of the telescopic plate 423 when isolating the leads 2, and effectively preventing the isolation plate 42 from affecting the isolation effect due to loosening. The limiting block 4211 at the upper end of the limiting groove 41101 restricts the connecting block 424 to prevent the telescopic plate 423 from detaching from the inside of the partition 421.

[0042] In one embodiment, the partition 421 has moving slots 42101 on both sides for the connecting block 424 to move, and a storage slot 42102 for placing the telescopic plate 423 is provided at the upper end of the partition 421.

[0043] This design is for reference. Figure 7 The movable slots 42101 on both sides of the partition 421 provide a clear moving path for the connecting block 424. When the partition 42 is raised or lowered, the connecting block 424 can move smoothly in the movable slots 42101 without being obstructed by the partition 421. The storage slot 42102 at the upper end of the partition 421 provides a dedicated storage space for the telescopic plate 423. When the telescopic plate 423 is in the retracted state, it can be neatly placed in the storage slot 42102, avoiding interference or damage to other components that may be caused by the random placement of the telescopic plate 423.

[0044] In one embodiment, the circuit breaker body 1 has a fixing groove 102 for installing fixing bolts 432.

[0045] This design is for reference. Figure 6 ,as well as Figure 7 The fixing groove 102 provides a clear positional guide for the installation of the fixing bolt 432. During the installation process, the operator does not need to perform additional measurement and positioning operations. He only needs to align the fixing bolt 432 with the fixing groove 102 for installation, which greatly saves installation time and improves installation efficiency.
