[0002] Circuit breakers are an important part of the electrical industry. When the circuit is working properly, the circuit breaker can close and disconnect the circuit. When a circuit fault occurs, the circuit breaker can automatically cut off the circuit to avoid endangering the safety of staff and the normal operation of equipment due to circuit faults. Due to the need for integrated intelligent remote control of circuit breakers, a remote control module needs to be added to the side of the circuit breaker, and the remote control module needs to take power or sample from the incoming or outgoing line ends of the circuit breaker. The power taking structure of an intelligent circuit breaker refers to a structure used to provide electrical energy for the control circuit and auxiliary devices such as sensors of the circuit breaker. These power taking structures usually need to obtain energy from the main circuit to realize real-time monitoring and control of the state of the circuit breaker.

[0029] Please refer to Figures 1-3 , a power-taking structure of a circuit breaker in this embodiment includes a PCB board 1 and several power-taking pieces 2 inserted on the PCB board 1. The PCB board 1 is fixed on the circuit breaker. A fixing component is arranged between the power-taking piece 2 and the PCB board 1, and the fixing component facilitates quickly fixing the power-taking piece 2 on the PCB board 1. The fixing component includes an insertion block 3 fixedly connected to the outer wall of the power-taking piece 2 and inserted into the inner side of the PCB board 1, an adjustment plate 5 slidably mounted on the outer wall of the PCB board 1, and a limit plate 7 fixedly connected to the bottom of the adjustment plate 5 and inserted into the upper end of the power-taking piece 2.

[0030] In this embodiment, an elastic piece 4 is fixedly connected to the bottom of the power-taking piece 2, and the number of elastic pieces 4 at the bottom of each power-taking piece 2 is set to two. By arranging the elastic piece 4, it is convenient for the power-taking piece 2 to stably contact the conductive part of the wiring board of the circuit breaker when inserted into the circuit breaker, improving the connection stability. At the same time, jacks adapted to the insertion blocks 3 are provided on the inner side of the PCB board 1, and the number of insertion blocks 3 on the outer side of each power-taking piece 2 is set to two. Through the provided jacks, it is convenient for the insertion blocks 3 to be stably docked with the PCB board 1, and the insertion blocks 3 are used to position the power-taking piece 2, facilitating the installation of the power-taking piece 2. In addition, slots adapted to the limit plates 7 are provided at the upper ends of the power-taking pieces 2, and the cross-section of the limit plate 7 is in an inverted U shape. Through the provided slots, it is convenient to achieve stable docking between the limit plate 7 and the power-taking piece 2, and the limit plate 7 can play a good limiting role on the power-taking piece 2, facilitating the fixing of the power-taking piece 2.

[0031] It should be noted that both the power-taking piece 2 and the elastic piece 4 are made of conductive metal, and the conductive metal includes copper and aluminum. The power-taking piece 2 and the elastic piece 4 made of conductive metal contact the conductive part of the wiring board of the circuit breaker to form power-taking. Under the elastic action of the elastic piece 4, the contact with the conductive part of the wiring board of the circuit breaker is closer and firmer, and the power-taking effect is good.

[0032] It should be added that a convex plate 6 is fixedly connected to the outer wall of the adjustment plate 5. By arranging the convex plate 6, it is convenient to grasp the adjustment plate 5 and facilitate the adjustment of the position of the adjustment plate 5.

[0033] Please refer to Figure 2, in this embodiment, an elastic component is provided between the adjusting plate 5 and the PCB board 1. The provided elastic component facilitates the elastic adjustment of the position of the fixing component.

Among them, the lower end of the spring 12 is fixedly connected to the upper end of the connecting rod 10, and the upper end of the spring 12 abuts against the inner wall of the fixing cylinder 11. The cooperation of the connecting rod 10 and the fixing cylinder 11 can play a guiding role for the spring 12, enabling the spring 12 to stretch and contract stably. The elastic action of the spring 12 facilitates the elastic adjustment of the positions of the mounting block 8, the adjusting plate 5, and the limiting plate 7, facilitating the loading and unloading of the power-taking piece 2.

The cooperation of the slider 9 and the sliding groove 13 can play a guiding role for the mounting block 8 and the adjusting plate 5.

[0036] The working principle of the above embodiment is as follows:

[0037] When this application is in use, the PCB board 1 is fixed on the circuit breaker. When the power-taking piece 2 is connected to the circuit breaker, by pushing the convex plate 6 to drive the adjusting plate 5 and the limiting plate 7 to move upward, and driving the mounting block 8 and the connecting rod 10 to move upward, the connecting rod 10 squeezes the spring 12. The plug block 3 on the power-taking piece 2 is kept in butt joint with the PCB board 1, and the spring 12 elastically resets the adjusting plate 5 and the limiting plate 7 again, so that the limiting plate 7 is kept in butt joint with the power-taking piece 2, and the convenient fixing of the power-taking piece 2 can be realized.
