Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and specifically to a space-optimized miniature circuit breaker. Background Technology

[0002] Miniature circuit breakers (MCBs) play a crucial role as essential protective devices in low-voltage power distribution systems, particularly in residential, commercial, and industrial applications. With the rapid development of smart grids and the Internet of Things (IoT), modern MCBs not only need basic overload and short-circuit protection but also require the integration of more intelligent functions, such as remote monitoring, status indication, fault diagnosis, and temperature monitoring, to meet the demands of intelligent management in modern power distribution systems.

[0003] Currently, the market offers a wide variety of miniature circuit breakers (MCBs), including products with different numbers of poles, tripping characteristics, and levels of intelligence, capable of adapting to various complex power distribution environments and application scenarios. With the development of electronic and miniaturization technologies, some advanced MCBs can even achieve advanced functions such as communication with host computers, parameter setting, and historical data recording. Furthermore, the manufacturing process of MCBs has been continuously optimized, significantly improving product reliability, accuracy, and service life, providing strong support for the safe and stable operation of electrical systems.

[0004] However, despite continuous advancements in miniature circuit breaker (MCB) technology, several pressing issues remain in practical applications. Due to limited internal space, existing MCBs present significant challenges when adding more intelligent functions, leading to a substantial increase in circuit board complexity. The limited space cannot accommodate a sufficient number of integrated components, hindering the effective installation of functional components such as motors. This severely restricts the functional expansion and performance improvement of intelligent MCBs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a space-optimized miniature circuit breaker. Through the space optimization structure of the recessed drive element, the internal space is redistributed in a three-dimensional manner, which significantly improves the space utilization rate and provides sufficient installation space for intelligent functional components.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A space-optimized miniature circuit breaker, comprising: The circuit breaker housing has an upper space and a lower space inside. Multiple gears are disposed inside the circuit breaker housing; A sinking gear, wherein the sinking gear is disposed in the lower space from the upper space; The circuit board is disposed within the upper space; The downward configuration of the downward gear increases the usable area of ​​the upper space, providing installation space for the circuit layout of the circuit board.

[0007] This utility model is further configured as follows: The sinking gear includes a first sinking gear and a second sinking gear, which are meshed together and are disposed in the lower space.

[0008] It also includes a motor, which is located below the circuit board and occupies the vertical space released after the sinking gear sinks down.

[0009] The first sinking gear is fixed in the lower space by the first support base, and the second sinking gear is fixed in the lower space by the second support base.

[0010] Compared with the prior art, the present invention has the following beneficial effects: Significantly improved space utilization: By redistributing the three-dimensional space through the sunken gear, the usable area of ​​the upper space increases, providing ample installation space for circuit boards and intelligent functional components, and completely solving the space limitation problem of traditional planar layout.

[0011] The integration of intelligent functions has been greatly improved: the space freed up by the sinking gear allows for the integration of more intelligent functional components on the circuit board than the traditional layout, supporting the simultaneous integration of multiple intelligent functions such as motors, remote monitoring modules, and status indicators, thus meeting the functional requirements of modern intelligent miniature circuit breakers.

[0012] The mechanical transmission performance remains stable: the gear transmission system after sinking can still maintain its original mechanical performance and reliability, without affecting the basic protection function of the circuit breaker. Attached Figure Description

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figure 1 As shown, this utility model provides a space-optimized miniature circuit breaker, which mainly includes a circuit breaker housing (1).

[0017] like Figure 2 , Figure 3 As shown, the circuit breaker housing (1) adopts a standard miniature circuit breaker housing structure, and the interior is divided into an upper space (2) and a lower space (3) through spatial design. The upper space is mainly used to install the circuit board, and the lower space is mainly used to accommodate the recessed gear transmission components. The above-mentioned layered design achieves effective separation of mechanical transmission function and circuit control function.

[0018] Multiple gears are installed inside the circuit breaker housing (1) to form a drive transmission system. The sinking gear (5) is a part of the multiple gears, which is sinking from its original position in the upper space (2) to the lower space (3), freeing up the upper installation space.

[0019] like Figure 4 , Figure 5 As shown, the sinking gear (5) includes a first sinking gear (9) and a second sinking gear (10), which are connected by gear meshing and are set together in the lower space (3). The first sinking gear (9) is fixed in the lower space by the first support seat (17), and the second sinking gear (10) is fixed in the lower space by the second support seat (18), ensuring the precise positioning and stable operation of the gear transmission.

[0020] A partition plate (15) is provided inside the circuit breaker housing (1) to divide the interior of the circuit breaker housing into an upper space (2) and a lower space (3). The circuit board (7) is set in the upper space (2), making full use of the space released by the sinker gear. The area of ​​the circuit board is 30-40% larger than that of a traditional planar layout circuit board, making it possible to integrate more electronic components.

[0021] The motor (14) is located below the circuit board, occupying the vertical space released after the sinking gear is lowered. The motor is fixed to one side of the circuit board by a mounting bracket (19).

[0022] Through the space optimization design of the recessed gear, the number of integrated intelligent functional components increases compared to the traditional layout. This significant improvement in integration enables miniature circuit breakers to simultaneously integrate multiple intelligent functions such as remote monitoring modules, status indication systems, fault diagnosis functions, and temperature monitoring devices.

[0023] The three-dimensional spatial layout not only improves the integration of functions, but also reserves ample space for future functional upgrades, greatly enhancing the product's scalability and market adaptability.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the protection scope of this utility model should still fall within the scope of the claims of this utility model.
