[0002] With the development of smart grid in my country, the realization of intelligent control of electrical appliances has become more and more urgent under the premise of requiring safe operation of the grid. Small circuit breakers with automatic reclosing have been vigorously developed, and various transmission mechanisms and linkage devices have emerged. When developing the reclosing device of small circuit breakers, the actuator shakes compared with the circuit breaker assembly when working due to the loose connection between the actuator and the circuit breaker assembly, which leads to the inability of the actuator to accurately and reliably promote the circuit breaker assembly to achieve opening and closing actions.

[0003] In particular, when there are a large number of circuit breakers, the transmission stroke of the transmission mechanism is long. Once the actuator shakes, it is very easy for the circuit breaker assembly to not be properly linked and tripped, and after tripping, the tripping mechanism may not return to the specified position, resulting in the failure to close the switch, which in turn causes the circuit breaker assembly to fail to open and close normally, and users cannot use electricity normally.

[0010] As a preferred technical solution of the present utility model: the latch is a hollow structure, and the latch and the enclosure are connected via reinforcing ribs.

[0011] By adopting the above technical solution, the beneficial effect of the utility model is as follows: two covers are used to cover the circuit breaker assembly, so that the contact area between the cover and the circuit breaker assembly is increased to ensure the stability of the two covers after installation, and then the connection parts on the two covers can be used to fix the actuator on one side of the circuit breaker assembly while protecting the circuit breaker assembly, so that the actuator can be stably and reliably located on one side of the circuit breaker assembly.

DETAILED DESCRIPTION

[0018] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a circuit breaker that is convenient for fixing an actuator, comprising a circuit breaker assembly 1 composed of a plurality of circuit breakers with the same structure, and an actuator 4 is movably installed on one side of the circuit breaker assembly 1; a first cover plate 2 is provided at the upper end of the circuit breaker assembly 1, and a second cover plate 3 is provided at the lower end of the circuit breaker assembly 1; after the first cover plate 2 and the second cover plate 3 are covered on the circuit breaker assembly 1, the first cover plate 2 is connected to the first connecting hole 5 provided at the upper end of the actuator 4 through the first connecting portion 22 provided thereon, and is connected to the second connecting hole 6 provided at the bottom of the actuator 4 through the second connecting portion 30 provided on the second cover plate 3.

[0020] In summary, two covers are used to cover the circuit breaker assembly 1, so that the contact area between the cover and the circuit breaker assembly 1 is increased to ensure the stability of the two covers after installation. Then, while the cover is used to protect the circuit breaker assembly 1, the connecting parts on the two covers can be used to fix the actuator 4 on one side of the circuit breaker assembly 1, so that the actuator 4 can be stably and reliably located on one side of the circuit breaker assembly 1.

[0021] Based on this, the movable connection between the actuator 4 and the circuit breaker assembly 1 can be achieved through a simple structural setting, which facilitates the installation and replacement of the actuator 4. In particular, the reliable connection between the two cover plates and the circuit breaker assembly 1 is utilized, so that the actuator 4 installed on the two cover plates has a reliable and stable working position, so as to reduce the problem of incomplete closing or opening of the circuit breaker assembly 1 caused by shaking of the actuator 4 during operation.

[0022] Furthermore, since the second cover plate 3 is also provided with a third connection portion 31 having the same structure as the second connection portion 30, after the second connection portion 30 and the third connection portion 31 are inserted into the second connection hole 6, and after the first connection portion 22 is inserted into the first connection hole 5, the connection line of the first connection portion 22, the second connection portion 30 and the third connection portion 31 is in a triangular shape. That is, after the first connection portion 22, the second connection portion 30 and the third connection portion 31 are connected to the actuator 4, the connection line of the three connection portions is in a triangular shape, so the stability of the actuator 4 after being connected to the first cover plate 2 and the second cover plate 3 can be further improved, thereby ensuring the stable and reliable operation of the actuator 4, so as to solve the problem that the circuit breaker assembly 1 is not completely opened or closed due to a long stroke.

[0023] On the basis of the above solution, since the first cover plate 2 and the second cover plate 3 are both provided with a latch 21 on one side facing the circuit breaker assembly 1, and are inserted into the circuit breaker assembly 1 through the latch 21, after the latch 21 is adapted and connected with the socket on the circuit breaker assembly 1, the stability of the first cover plate 2 and the second cover plate 3 after being combined with the circuit breaker assembly 1 can be ensured. Furthermore, since the latch 21 is a hollow structure, it is convenient for the bolt to pass through the latch 21 and be connected with the circuit breaker assembly 1, so the stability of the two cover plates after being connected with the circuit breaker assembly 1 can be further ensured.

[0024] At the same time, since the first cover plate 2 and the second cover plate 3 are both provided with through holes 23 for the wires to pass through on the sides facing the circuit breaker assembly 1 , it is convenient for the wires to be connected to the wiring terminals on the circuit breaker assembly 1 .

[0025] In order to reduce the phenomenon of the first cover plate 2 and the second cover plate 3 being concave in the process of being fixed to the circuit breaker assembly 1, a surrounding plate 20 is further provided at the outer edge of the through hole 23, and after the first cover plate 2 and the circuit breaker assembly 1 are closed, the side of the surrounding plate 20 away from the first cover plate 2 abuts against the circuit breaker assembly 1. Therefore, the surrounding plate 20 can be used to enhance the anti-twisting ability of the cover plate, and the surrounding plate 20 can also be used to support the cover plate on the circuit breaker assembly 1 to avoid the phenomenon of the cover plate being concave in the process of tightening.

[0026] Furthermore, since the latch 21 and the enclosure 20 are connected by the reinforcing ribs 24, the reinforcing ribs 24 can be used to further enhance the structural strength of the first cover plate 2 and the second cover plate 3, thereby ensuring that the two cover plates will not be concave in the middle, warped at both ends, or twisted along the central axis of the cover plates after being fixed.

[0027] In summary, by optimizing the structure of the two cover plates, the cover plates have sufficient structural strength after installation, thereby ensuring the stability of the actuator 4 after connection with the cover plates, thereby ensuring that the actuator 4 can reliably and accurately realize the opening and closing actions of the circuit breaker assembly 1.

[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
