[0002] A circuit breaker, also known as an automatic switch or air switch, is an electrical device used to protect circuits from damage caused by overloads and short circuits.

[0003] A smart circuit breaker is an electrical device that integrates the functions of a traditional circuit breaker with modern electronic technology, communication technology, and intelligent functions.

[0004] The existing intelligent circuit breaker has the following shortcomings:

[0005] Currently, the common method for connecting circuit breakers and cables is the bolt-plate connection method. The specific operation involves accurately inserting the cable terminals into the circuit breaker's connection port, and then tightening the bolts corresponding to each connection hole in sequence. The clamping force generated by the pressure plate achieves a stable connection between the terminals and the circuit breaker. However, this method requires tightening the bolts in the connection holes, which is cumbersome and time-consuming. At the same time, the installation process requires a large amount of operating space and manpower. In large-scale construction or work in confined spaces, this greatly increases the difficulty of construction and reduces installation efficiency. Utility Model Content

The shaft end of the slide rod 104 is fixedly connected to the inner wall of the first slider 102, so that the two ends of the first compression spring 106 are connected to ensure normal use in the future.

[0027] like Figure 3 As shown, the outer wall of the first connecting plate 101 is fixedly connected with a first limiting rod 105. The inner wall of the first limiting rod 105 is slidably connected to the outer wall of the block 103. By setting the first limiting rod 105, the stability of the block 103 when sliding back and forth can be improved.

[0028] like Figure 2 and Figure 3 As shown, the outer wall of the first connecting plate 101 is fixedly connected with a connecting cylinder 110. The inner wall of the connecting cylinder 110 is slidably connected to the outer wall of the connecting rope 107. By setting the connecting cylinder 110, the stability of the connecting rope 107 during movement can be improved.

[0029] like Figure 3 As shown, the outer wall of the second slider 112 is fixedly connected with a limiting plate 109, and the inner wall of the second connecting plate 108 is fixedly connected with a second limiting rod 113. The outer wall of the second limiting rod 113 is slidably connected to the inner wall of the second slider 112, and the outer wall of the second slider 112 is fixedly connected to one end of the connecting rope 107. The limiting plate 109 can limit the wiring terminal, and the second limiting rod 113 can guide the second slider 112 to slide stably up and down within the second connecting plate 108.

[0030] like Figure 4 and Figure 5 As shown, the equipment component 2 includes a circuit breaker body 201. Connection ports 204 are provided on both the front and back of the circuit breaker body 201. A set of sealing boxes 203 are slidably connected to the top of the circuit breaker body 201. Bolts 205 are threaded through the top of each sealing box 203. A housing 209 is fixedly connected to one side of the top of the sealing box 203. A baffle 210 is hinged to the top of the housing 209. A sensor interface 208 and a communication interface 207 are provided on the outer wall of the housing 209. The bottom threads of the bolts 205 penetrate the inner wall of the sealing boxes 203. The bolts 205 facilitate the user's disassembly and assembly of the sealing boxes 203. The sensor interface 208 allows connection to various sensors. The communication interface 207 enables the circuit breaker body 201 to communicate with a remote monitoring center or other external devices.

[0031] like Figure 4 and Figure 5 As shown, a pull rod 202 is provided through the inner wall of the sealing box 203. A sealing ring 206 is fixedly connected to the top of the sealing box 203.

Through the pull rod 202, the insulating pad 211 and the third compression spring 212, a secondary restriction function can be achieved on the wiring terminals.

[0032] The usage and working principle of this device are as follows: After the terminal block on the cable is inserted into the connector 204, the user needs to push the corresponding block 103 so that it moves closer together on the first limiting rod 105. During this process, the block 103 will drive the first slider 102 to move, causing the slider 104 and the first compression spring 106 to be compressed. At the same time, the connecting rope 107 is stressed and moves inside the connecting cylinder 110, driving the connected second slider 112 to slide on the second limiting rod 113. The second compression spring 111 is thus compressed, and the limiting plate 109 moves down or up accordingly. When the blocks 103 move closer together to the appropriate position, the user releases the blocks 103. At this time, the first compression spring 106... The elastic force will reset the first slider 102, and the connecting rope 107 and the second slider 112 will no longer be restrained. The second slider 112, with the help of the elastic force of the second compression spring 111, applies force to the limiting plate 109, causing the limiting plate 109 to move to the outside of the connection port 204, initially fixing the wiring terminal in the connection port 204. After the initial fixing is completed, the user pulls the corresponding pull rod 202 upward, and the third compression spring 212 and the insulating pad 211 are subjected to force. The insulating pad 211 moves upward. When it is pulled to a certain position and the pull rod 202 is released, the insulating pad 211 will apply force to the wiring terminal again with the help of the elastic force of the third compression spring 212, realizing secondary fixing and ensuring that the wiring terminal is stably connected to the circuit breaker body 201.
