[0008] The circuit breaker is provided with two limiting plates connected by connecting columns at the top and bottom. Multiple limiting holes are evenly arranged on the limiting plates, and multiple wires and rubber sleeves pass through the multiple limiting holes respectively.
[0009] The bottom of the rubber sleeve is set in a ring shape, and an annular step is provided at the edge of the upper surface of the ring structure. The bottom of the rubber sleeve is set in a frustum shape above the step. The diameter of the limiting hole is between the outer diameter of the top edge and the bottom edge of the frustum structure. The limiting plate squeezes the circuit breaker until it contacts the lower surface of the step and stops. The bottom of the rubber sleeve deforms and extends, sealing the gap between the bottom of the limiting hole and the side of the conductor and the circuit breaker.
[0010] Preferably, the top of the circuit breaker is provided with a horizontal groove, the conductor is located at the center of the horizontal groove, and the limiting plate is inserted into the horizontal groove, and the width of the limiting plate is equal to the width of the horizontal groove.

[0014] In summary, this utility model has the following beneficial technical effects:
[0015] 1. A rubber sleeve is provided at the top of the conductor extending from the circuit breaker. The rubber sleeve can effectively prevent the conductor from being damaged by direct friction, pulling and other external factors at the connection point with the circuit breaker, extend the service life of the conductor, and ensure the stability of the circuit.
[0016] 2. The limit plate can restrict the vertical displacement of the circuit breaker, preventing the circuit breaker from becoming loose or misaligned due to vibration, collision or other factors. In conjunction with the rubber sleeve, it can keep the wire connection parts neat.
[0017] 3. The bottom of the rubber sleeve is deformed and extended by compression, which can improve the stability of the circuit breaker assembly and seal the gap between the side of the conductor and the circuit breaker, further enhancing the protection of the conductor connection part. It effectively prevents dust, moisture and other impurities from entering the connection gap between the conductor and the circuit breaker, reducing the risk of electrical faults caused by impurities.

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0026] An automated electrical engineering power distribution circuit breaker, with reference to Figure 1 , Figure 3 , Figure 4 and Figure 5 It includes multiple circuit breakers 1, and wires 2 connected to the top and bottom of the circuit breakers 1. The wires 2 are covered with a rubber sleeve 6 at the top of the circuit breaker 1 to protect the wires 2. The rubber sleeve 6 can effectively prevent the wires 2 from being damaged by direct friction, pulling and other external factors at the connection point with the circuit breaker 1, extend the service life of the wires 2, and ensure the stability of the circuit.
[0027] Multiple circuit breakers 1 are provided with two limiting plates 3 connected and squeezed by connecting columns 4 at the top and bottom, which can install multiple circuit breakers 1 together, facilitate centralized control and management, make efficient use of space, and improve system reliability.
[0028] The limiting plate 3 is evenly provided with multiple limiting holes 7, and multiple wires 2 and rubber sleeves 6 pass through multiple limiting holes 7 respectively. On the one hand, the limiting plate 3 can limit the vertical displacement of the circuit breaker 1 and prevent the circuit breaker 1 from becoming loose or misaligned due to factors such as vibration and collision; on the other hand, through cooperation with the rubber sleeves 6, it can achieve the regularization of the connection parts of the wires 2.
[0029] Reference Figure 3 The bottom of the rubber sleeve 6 is set in a ring shape, and an annular step 8 is provided at the edge of the upper surface of the ring structure. The bottom of the rubber sleeve 6 is set in a frustum shape above the step 8, which can be used to guide the sliding of the limiting plate 3. The diameter of the limiting hole 7 is located between the outer diameter of the top edge and the bottom edge of the frustum structure. The limiting plate 3 presses the circuit breaker 1 until it contacts the lower surface of the step 8 and stops. The bottom of the rubber sleeve 6 deforms and extends, which can improve the stability of the circuit breaker 1 after assembly, and seal the gap between the bottom of the limiting hole 7 and the side of the conductor 2 and the circuit breaker 1. This further enhances the protection of the connection part of the conductor 2, effectively prevents dust, water vapor and other impurities from entering the connection gap between the conductor 2 and the circuit breaker 1, and reduces the risk of electrical faults caused by impurities.
[0030] Furthermore, the limiting hole 7 is designed in the shape of a frustum, and the limiting hole 7 is designed to be narrower at the top and wider at the bottom, so that the limiting hole 7 can quickly fit into the bottom frustum-shaped structure of the rubber sleeve 6, resulting in better stability and sealing effect.
[0031] Reference Figure 2The top of the circuit breaker 1 is provided with a horizontal groove 5, the conductor 2 is located at the center of the horizontal groove 5, and the limiting plate 3 is inserted into the horizontal groove 5. The width of the limiting plate 3 is equal to the width of the horizontal groove 5. The cooperation between the horizontal groove 5 and the limiting plate 3 allows the limiting plate 3 to be installed more stably on the circuit breaker 1, improving the stability of the overall structure, while ensuring that the position of the conductor 2 at the connection point is accurate and not easily deviated.
[0032] Reference Figure 1 and Figure 4 The top and bottom ends of the connecting post 4 penetrate the top and bottom of the two limiting plates 3, respectively. A nut is threaded onto the protruding part of the connecting post 4, facilitating tightening of the connecting post 4 and ensuring a tight connection between the two limiting plates 3. This firmly secures the circuit breaker 1 between them, further enhancing the stability of the overall structure. The side of the connecting post 4 contacts the nearest circuit breaker 1. The contact point on the connecting post 4 with the circuit breaker 1 is designed as a regular square prism to prevent the connecting post 4 from rotating relative to the circuit breaker 1, ensuring the reliability of the connection structure and avoiding problems such as component loosening caused by the rotation of the connecting post 4.
[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
