[0053] like Figures 1-9 As shown, a circuit breaker assembly 100 according to an embodiment of the present invention includes: an insulating housing 1, a plurality of conductive plates 41 and a cutting device.

[0054] Multiple conductive plates 41 are arranged at intervals in the insulating shell 1, and the multiple conductive plates 41 include a first conductive plate 42 and a second conductive plate 43. The cutting device includes a first cutting device 2 and a second cutting device 3. The first cutting device 2 and the second cutting device 3 are both arranged in the insulating shell 1. The first cutting device 2 is used to break the first conductive plate 42, and the second cutting device 3 is used to break the second conductive plate 43.

[0055] The circuit breaker assembly 100 is a device capable of carrying current in a normal circuit and interrupting current in an abnormal circuit under specified conditions. When a severe overload, short circuit, or undervoltage fault occurs in an electrical system, particularly a high-voltage circuit, the circuit breaker assembly automatically disconnects the conductive circuit. The circuit breaker assembly 100 is safe, reliable, highly automated, and widely applicable.

[0056] Specifically, the circuit breaker assembly 100 is provided with an insulating shell 1, which can be set as an integral part made by injection molding, etc., and the insulating shell 1 is set at the outermost side of the circuit breaker assembly 100, which can provide support and protection for the internal components of the circuit breaker assembly 100, and an installation space can be formed in the insulating shell 1. The components of the circuit breaker assembly 100 can all be installed in the installation space of the insulating shell 1, thereby improving the integration of the circuit breaker assembly 100. The insulating shell 1 is set to an insulating material, which can insulate the internal components of the insulating shell 1 from the outside, ensure the operational reliability of the internal components, and avoid conduction from the inside of the insulating shell 1 to the outside, thereby improving the installation safety.

[0057] Furthermore, a conductive plate 41 is installed in the insulating shell 1. The conductive plate 41 can be set to multiple, at least part of the multiple conductive plates 41 extends outside the insulating shell 1 and can be connected to the external circuit for conduction. The multiple conductive plates 41 are arranged at intervals in the insulating shell 1 and can play the role of transmitting current and connecting electrical equipment in the conductive circuit. A first conductive plate 42 and a second conductive plate 43 are provided among the multiple conductive plates 41. The first conductive plate 42 and the second conductive plate 43 are also distributed at intervals to avoid mutual interference. The first conductive plate 42 and the second conductive plate 43 can be connected to two conductive circuits respectively.

[0058] The circuit breaker assembly 100 is also provided with a cutting device. There are two cutting devices, which are respectively provided as a first cutting device 2 and a second cutting device 3. The first cutting device 2 and the second cutting device 3 are both installed in the insulating shell 1, and the first cutting device 2 and the second cutting device 3 are spaced apart in the insulating shell 1. The first cutting device 2 is provided corresponding to the first conductive plate 42, and the first cutting device 2 can move toward the first conductive plate 42 to break the first conductive plate 42, thereby cutting off the circuit where the first conductive plate 42 is located. The second cutting device 3 is provided corresponding to the second conductive plate 43, and the second cutting device 3 can move toward the second conductive plate 43 to break the second conductive plate 43, thereby cutting off the circuit where the second conductive plate 43 is located, thereby protecting the conductive circuit and the electrical components in the conductive circuit.

[0059] The two cutting devices and the plurality of conductive plates 41 are all integrated and installed in the insulating shell 1, thereby reducing the space occupied by the circuit breaker assembly 100. The structure is simple and the setting is highly integrated, which can reduce the setting cost and thus improve the lightweight. The insulating shell 1 is provided to ensure the structural stability of the circuit breaker assembly 100 during and after the operation, so as to improve the safety of the circuit breaker assembly 100. In actual setting, the first cutting device 2 and the second cutting device 3 can be set to synchronous action or to separate action, that is, the first cutting device 2 and the second cutting device 3 can be set to simultaneously cut the first conductive plate 42 and the second conductive plate 43, or the second cutting device 2 can be set to not work when the first cutting device 2 cuts the first conductive plate 42, or the first cutting device is not work when the second cutting device 3 cuts the second conductive plate 43, thereby improving the flexibility of use. The number of corresponding cutting devices can be set according to the actual number of circuits, that is, the cutting device is not limited to being set to two.

[0060] According to the circuit breaker assembly 100 of the embodiment of the present invention, by integrating multiple conductive plates 41 and two disconnecting devices into an insulating housing 1, the space occupied by the circuit breaker assembly 100 can be reduced. The structure is simple and the installation is highly integrated, which can reduce the installation cost and thus improve the lightweight. In addition, the provision of the insulating housing 1 can improve the structural strength and ensure the structural stability of the circuit breaker assembly 100 during and after operation, thereby improving the safety of the circuit breaker assembly 100, achieving better use effects, and expanding the scope of application.

[0061] In some embodiments, the insulating housing 1 is a one-piece structure, which can further improve the integration of the circuit breaker assembly 100. Specifically, the insulating housing 1 can be configured as a one-piece piece manufactured by injection molding. Injection molding can increase the production speed of the insulating housing 1, thereby improving the production efficiency of the insulating housing 1. The insulating housing 1 is disposed at the outermost side of the circuit breaker assembly 100 to provide support and protection for the internal components of the circuit breaker assembly 100. The one-piece structure of the insulating housing 1 also improves the structural strength of the insulating housing 1, ensuring that the conductive plate 41 located inside the insulating housing 1 is separated from the outside world, thereby improving operational reliability.

[0062] In some embodiments, the insulating shell 1 includes an intermediate baffle 11, which is arranged between the first conductive plate 42 and the second conductive plate 43. The first cutting device 2 is configured to apply a force toward the intermediate baffle 11 to the first conductive plate 42 to disconnect the first conductive plate 42, and the second cutting device 3 is configured to apply a force toward the intermediate baffle 11 to the second conductive plate 43 to disconnect the second conductive plate 43.

[0063] Specifically, the plurality of conductive plates 41 and the two cutting devices are all arranged in the insulating housing 1, and an intermediate baffle 11 is provided in the insulating housing 1. The intermediate baffle 11 can be provided in the middle of the installation space of the insulating housing 1, thereby dividing the installation space of the insulating housing 1 into two parts, such as Figure 3 and Figure 8 As shown, the first conductive plate 42 and the second conductive plate 43 are spaced apart and distributed in the insulating shell 1, and the first conductive plate 42 and the second conductive plate 43 can be respectively located in two installation spaces, that is, the intermediate baffle 11 can be set between the first conductive plate 42 and the second conductive plate 43.

[0064] Furthermore, the first cutting device 2 is arranged on the side of the first conductive plate 42 away from the intermediate baffle 11, and the first cutting device 2 can apply a breaking force toward the intermediate baffle 11 to the first conductive plate 42 to break the first conductive plate 42. The second cutting device 3 is arranged on the side of the second conductive plate 43 away from the intermediate baffle 11, and the second cutting device 3 can apply a breaking force toward the intermediate baffle 11 to the second conductive plate 43 to break the second conductive plate 43. An intermediate baffle 11 is provided between the first conductive plate 42 and the second conductive plate 43, thereby improving the structural strength of the portion of the insulating shell 1 located between the two cutting devices to ensure the structural stability of the circuit breaker assembly 100 during and after the operation, thereby improving the safety of the circuit breaker assembly 100.

[0065] It can be understood that the two cutting devices act independently of each other, and each cutting device acts on its own conductive plate 41. In this way, when only one of the conductive plates 41 needs to be cut, only the corresponding cutting device can be operated. At the same time, the cutting device corresponding to the other conductive plate 41 can be well isolated from the cutting device that has been acted on by the intermediate baffle 11, thereby avoiding the interference of the first cutting device on the later cutting device when the two cutting devices are performing the cutting operations one after another, that is, avoiding the impact of the first-acting cutting device on both conductive plates 41, thereby achieving effective separation of the two cutting devices, ensuring the safety of the structure, and realizing accurate and independent control of the two conductive plates 41.

[0066] When the first cutting device 2 and the second cutting device 3 work at the same time, the first conductive plate 42 and the second conductive plate 43 can be cut off at the same time. At this time, the intermediate baffle 11 can isolate the mutual interference and arcing between the broken parts of the first conductive plate 42 and the second conductive plate 43, thereby ensuring the safety of the structure.

[0067] In some embodiments, a first weak portion 421 and a second weak portion 422 are provided on the first conductive plate 42. When the first cutting device 2 impacts the first conductive plate 42, the first weak portion 421 is disconnected, and a portion of the first conductive plate 42 is flipped around the second weak portion 422 toward the middle baffle 11.

[0068] Specifically, if Figure 3 As shown, a first conductive plate 42 is provided in the insulating shell 1, and the first conductive plate 42 is provided on one side of the intermediate baffle 11. A first cutting device 2 is provided corresponding to the first conductive plate 42. The first cutting device 2 can apply a force to the first conductive plate 42 to break the first conductive plate 42, and the first conductive plate 42 is provided with a first weak portion 421 and a second weak portion 422. The first weak portion 421 and the second weak portion 422 can both be set as a weakening groove or other structure that can weaken the local structural strength of the conductive plate 41. The structural strength of the first weak portion 421 and the second weak portion 422 is set to be lower than the structural strength of the rest of the first conductive plate 42, and the structural strength at the first weak portion 421 can be set to be lower than the structural strength at the second weak portion 422, that is, the thickness at the first weak portion 421 can be set to be smaller than the thickness at the second weak portion 422.

[0069] Furthermore, when the first cutting device 2 applies an impact force to the first conductive plate 42, the first weak portion 421 can be disconnected due to its low structural strength, and the structural strength of the second weak portion 422 is set to be greater than the structural strength of the first weak portion 421 and less than the structural strength of other parts of the first conductive plate 42. Therefore, while ensuring that the second weak portion 422 is not broken, part of the first conductive plate 42 can be flipped around the second weak portion 422 toward the middle baffle 11, so that the first cutting device 2 can break the first conductive plate 42, which can ensure the breaking reliability of the first conductive plate 42, and after being broken, the first conductive plate 42 can be flipped toward the middle baffle 11, thereby avoiding the first conductive plate 42 from affecting the remaining conductive plates 41, thereby ensuring the reliability of each conductive plate 41.

[0070] In some embodiments, the insulating shell 1 also includes a first rib 111, which is arranged on the side of the intermediate baffle 11 close to the first conductive plate 42, and the width of the first rib 111 close to the first weak portion 421 is greater than the width of the first rib 111 close to the second weak portion 422.

[0071] Specifically, if Figure 4 and Figure 8As shown, the insulating shell 1 is also provided with a first rib 111, which can be set as a plate-like structure, and the first rib 111 is arranged on the side of the insulating shell 1 close to the first cutting device 2, that is, the first rib 111 is arranged on the side of the intermediate baffle 11 close to the first conductive plate 42, the first rib 111 is connected to the intermediate baffle 11, and the first rib 111 can be connected to the intermediate baffle 11 by a connector or integral molding. When the first cutting device 2 breaks the first conductive plate 42, part of the first conductive plate 42 can move toward the first rib 111. The intermediate baffle 11 is provided with the first rib 111, which can improve the structural strength of the intermediate baffle 11, and thereby improve the overall structural strength of the insulating shell 1.

[0072] Furthermore, when the first cutting device 2 impacts the first conductive plate 42, the first weak portion 421 can be disconnected, and part of the first conductive plate 42 can be flipped around the second weak portion 422 toward the first rib 111, so that the first weak portion 421 of the first conductive plate 42 can approach the first rib 111, and the width of the first rib 111 close to the first weak portion 421 is set to be greater than the width of the first rib 111 close to the second weak portion 422, that is, the width of the first rib 111 close to the first weak portion 421 is set to a, and the width of the first rib 111 close to the second weak portion 422 is set to b, and a>b is satisfied, which can improve the structural strength of the first rib 111 close to the first weak portion 421, and thus avoid the first rib 111 from breaking after the first weak portion 421 approaches the first rib 111, thereby ensuring the reliability of the first rib 111.

[0073] In some embodiments, the thickness of the intermediate baffle 11 near the first weak portion 421 is greater than the thickness of the intermediate baffle 11 near the second weak portion 422. When the first cutting device 2 impacts the first conductive plate 42, the first weak portion 421 can be disconnected, and a portion of the first conductive plate 42 can be flipped around the second weak portion 422 toward the intermediate baffle 11, so that the first weak portion 421 of the first conductive plate 42 can approach the intermediate baffle 11. Setting the width of the intermediate baffle 11 near the first weak portion 421 to be greater than the width of the intermediate baffle 11 near the second weak portion 422 can improve the structural strength of the intermediate baffle 11 near the first weak portion 421, thereby avoiding the intermediate baffle 11 from breaking after the first weak portion 421 approaches the intermediate baffle 11, thereby ensuring the reliability of the intermediate baffle 11.

[0074] In some embodiments, the first rib 111 is integrally formed on a side of the middle baffle 11 close to the first conductive plate 42 , and the width of the first rib 111 is configured to gradually decrease along the distribution direction of the first weak portion 421 and the second weak portion 422 .

[0075] Specifically, if Figure 4 and Figure 8 As shown, the insulating shell 1 is also provided with a first rib 111, which is arranged on the side of the intermediate baffle 11 close to the first conductive plate 42, and the first rib 111 can be connected to the intermediate baffle 11 by integral molding. The first rib 111 and the intermediate baffle 11 are arranged to be integrally molded to improve the connection reliability between the first rib 111 and the intermediate baffle 11. When the first cutting device 2 breaks the first conductive plate 42, part of the first conductive plate 42 can move toward the first rib 111. The intermediate baffle 11 is provided with the first rib 111, and the first rib 111 can be set as a triangular plate. The triangle has stability, thereby ensuring the structural strength of the intermediate baffle 11, so as to improve the overall structural strength of the insulating shell 1.

[0076] Furthermore, when the first cutting device 2 impacts the first conductive plate 42, the first weak portion 421 can be disconnected, and part of the first conductive plate 42 can be flipped around the second weak portion 422 toward the first rib 111, so that the first weak portion 421 of the first conductive plate 42 can approach the first rib 111, and the width of the first rib 111 is set to gradually decrease along the distribution direction of the first weak portion 421 and the second weak portion 422, so that the width of the first rib 111 close to the first weak portion 421 can be set to be greater than the width of the first rib 111 close to the second weak portion 422, thereby improving the structural strength of the first rib 111 close to the first weak portion 421, so as to avoid the first rib 111 from breaking after the first weak portion 421 approaches the first rib 111, thereby ensuring the reliability of the first rib 111.

[0077] In some embodiments, a third weak portion 431 and a fourth weak portion 432 are provided on the second conductive plate 43. When the second cutting device 3 impacts the second conductive plate 43, the third weak portion 431 is disconnected, and a portion of the second conductive plate 43 is flipped around the fourth weak portion 432 toward the middle baffle 11.

[0078] Specifically, if Figure 3 As shown, a second conductive plate 43 is provided in the insulating shell 1, and the second conductive plate 43 is provided on one side of the intermediate baffle 11. A second cutting device 3 is provided corresponding to the second conductive plate 43. The second cutting device 3 can apply a force to the second conductive plate 43 to break the second conductive plate 43, and the second conductive plate 43 is provided with a third weak portion 431 and a fourth weak portion 432. The third weak portion 431 and the fourth weak portion 432 can both be set as weakening grooves, etc. The structural strength of the third weak portion 431 and the fourth weak portion 432 is set to be lower than the structural strength of the rest of the second conductive plate 43, and the structural strength at the third weak portion 431 can be set to be lower than the structural strength at the fourth weak portion 432, that is, the thickness at the third weak portion 431 can be set to be smaller than the thickness at the fourth weak portion 432.

[0079] Furthermore, when the second cutting device 3 applies an impact force to the second conductive plate 43, the third weak portion 431 can be disconnected due to its low structural strength, and the structural strength of the fourth weak portion 432 is set to be greater than the structural strength of the third weak portion 431 and less than the structural strength of other parts of the second conductive plate 43. Therefore, while ensuring that the fourth weak portion 432 is not broken, part of the second conductive plate 43 can be flipped around the fourth weak portion 432 toward the middle baffle 11, so that the second cutting device 3 can break the second conductive plate 43, which can ensure the breaking reliability of the second conductive plate 43, and after being broken, the second conductive plate 43 can be flipped toward the middle baffle 11, thereby preventing the second conductive plate 43 from affecting the remaining conductive plates 41, thereby ensuring the reliability of use of each conductive plate 41.

Setting the width of the intermediate baffle 11 near the third weak portion 431 to be greater than the width of the intermediate baffle 11 near the fourth weak portion 432 can improve the structural strength of the intermediate baffle 11 near the third weak portion 431, thereby avoiding the intermediate baffle 11 from breaking after the third weak portion 431 approaches the intermediate baffle 11, thereby ensuring the reliability of the intermediate baffle 11.
