Description

Plug-in modular circuit breaker Technical Field

[0001] This utility model relates to a low-voltage circuit breaker, and more particularly to a pluggable modular circuit breaker, belonging to the field of electrical equipment technology. Background Technology

[0002] Circuit breakers are essential devices for circuit protection, quickly cutting off power when an abnormality is detected in the circuit, thus protecting the safety of the circuit and equipment. Existing circuit breakers all use an integrated design, with both primary and secondary circuits housed in the same casing. Damage to any part requires replacing the entire circuit breaker. Due to the limited space and compact installation within distribution boxes, replacing the entire circuit breaker is time-consuming and can cause prolonged power outages in the distribution area, affecting power supply reliability and user satisfaction. Summary of the Invention

[0003] The purpose of this invention is to provide a pluggable modular circuit breaker, which has a simple structure, facilitates quick plugging and unplugging of modules and replacement, and improves the efficiency of maintenance and repair.

[0004] The present invention adopts the following technical solution: a pluggable modular circuit breaker, including a circuit breaker base, a top cover and a module. The top cover is installed on the circuit breaker base. The top cover has a cavity. The module is installed in the cavity. The cavity has a first through hole at the bottom. An adapter plate is installed on the back of the top cover corresponding to the cavity position. The adapter plate has a socket. The socket passes through the first through hole.

[0005] Preferably, the module includes a bottom shell and a cover, with an elastic support provided on the side of the bottom shell, a concave limiting platform provided on the side of the cavity, and a square hole provided on the inner side of the concave limiting platform to match the elastic support.

[0006] Preferably, the elastic support is an "L"-shaped support with a free end at the top. A limiting block is provided at the free end, and the limiting block normally locks the concave limiting platform.

[0007] Preferably, the limiting block is an inverted triangle formed on the outer side of the "L"-shaped bracket.

[0008] Preferably, the cover has guide slots, the power board and the main board are installed inside the module, the main board has long pins, the power board has a second through hole, the long pins pass through the second through hole and the corresponding slot on the cover, the power board has pins, and the pins pass through another corresponding slot on the cover.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. The plug-in modular structure allows for quick plugging and unplugging and replacement of modules without disassembling the entire circuit breaker, greatly improving maintenance efficiency, reducing maintenance and replacement costs, and enhancing the economic efficiency of the equipment.

[0011] 2. The upper cover cavity has a recessed limiting platform on its side, facilitating easy insertion and removal of the module by hand. Simultaneously, the elastic support on the side of the module deforms easily during insertion and automatically pops outward to limit movement after insertion, making operation simple and quick.

[0012] 3. After the module is inserted, the inverted triangular limit block 3-5 formed by its free end abuts against the limit platform, which can effectively prevent the module from loosening, ensure reliable fixation, and ensure the stable operation of the circuit breaker.

[0013] 4. The design of the adapter plate makes the electrical connection between the module and the circuit breaker base more reliable, and also facilitates compatibility and replacement of different types of modules. Attached Figure Description

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] As shown in Figure 1, the pluggable modular circuit breaker includes a circuit breaker base 1, a top cover 2, and a module 3. The top cover 2 is mounted on the circuit breaker base 1 and has a cavity 2-1. The module 3 is installed in the cavity 2-1. The cavity has a first through hole 2-2 at its bottom. An adapter plate 4 is installed on the back of the top cover 2 corresponding to the cavity position. The adapter plate has a socket 4-1 that passes through the first through hole 2-2. By placing the module in a specially designed hollow area on the top cover, it is easy to quickly assemble and disassemble the module for maintenance or replacement, thus modularizing the main components.

[0022] Specifically, module 3 includes a bottom shell 3-1 and a cover 3-2. An elastic bracket 3-4 is provided on the side of the bottom shell, and a recessed limiting platform 2-3 is provided on the side of the cavity 2-1. A square hole 2-4 matching the elastic bracket is provided on the inner side of the recessed limiting platform. The elastic bracket on the side of the module serves both as a guide for insertion and as a positioning element.

[0023] Specifically, the elastic bracket 3-4 is an "L"-shaped bracket with a free end at the top. A limiting block is installed at the free end, which normally locks the concave limiting platform 2-3. After the elastic bracket is inserted into the square hole, the outer elastic is released to lock the concave limiting platform for limiting and blocking.

[0024] Specifically, the limiting blocks 3-5 are inverted triangles formed on the outer side of the "L"-shaped bracket. This structure can effectively provide a limiting function.

[0025] Specifically, the cover 3-2 has guide slots 3-3. The power board 6 and the main board 5 are installed inside module 3. The main board has long pin headers 5-1, and the power board has a second through hole 6-2. The long pin headers 5-1 pass through the second through hole 6-2 and the corresponding slots 3-3 on the cover 3-2. The power board also has header pins 6-1, which pass through another corresponding slot on the cover. The power board 6 and the main board 5 are connected at the corners by connecting posts 6-3. This structural design facilitates the routing of header pins from the main board and the power supply, adapting to the overall modular design.

[0026] When inserting the module, the user pinches the upper end of the module's elastic support with their fingers, causing the support to retract inwards and smoothly enter the square hole. After insertion, the elastic support returns to its original position, and the inverted triangular limiting block presses against the back of the limiting platform 2-3, preventing the module from loosening. Once the module is in place, the guide slot 3-3 of module 3 inserts into the first through hole 2-2 of cavity 2-1, and the pins 5-1 and 6-1 on the circuit board insert into the socket 4-1 on adapter board 4, achieving electrical connection between the module and adapter board 4.

[0027] The pluggable modular circuit breaker of this invention has a simple structure, which facilitates the quick plugging and unplugging and replacement of modules, improves the efficiency of maintenance and repair, and reduces replacement costs, thus having high practicality and economy.

[0028] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
