[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0024] Please refer to Figs. 1-3 The present application provides a technical solution: a large-current shunt module for direct current power, comprising an insulating shell, a plug assembly 9 installed on the insulating shell for connecting to an external power source, and a plurality of connectors 12 for shunting current, a power distribution structure for electrically connecting the plug assembly 9 and the connectors 12 is further arranged in the insulating shell, and an assembly structure is arranged on the insulating shell, and the insulating shell is assembled and fixed with accessories through the assembly structure.

[0025] The plug assembly 9 is an interface for current to enter the shunt module, used for connecting an external power source. The connector 12 is an interface for current to be led out of the shunt module, also in the form of a plug, used for distributing current to other parts of the system.

[0026] The large direct current of the external power source is introduced into the power distribution structure through the plug assembly 9, and is transmitted to the plurality of connectors 12 connected with the copper bars, achieving the purpose of current shunting.

[0027] The design of the assembly structure ensures the stability and reliability of the shunt module under various operating conditions, ensures the physical stability of the shunt module, and also improves the adaptability and long-term reliability of the module to environmental changes, thereby ensuring the stable operation of the entire direct current power system.

[0028] Specifically, as shown in Figs. 1-3 The insulating shell includes a fixed lower shell 1 and an upper shell 2, the plug assembly 9 is fixed on the upper shell 2, and the connector 12 is fixed with the lower shell 1; the lower shell 1 and the upper shell 2 are injection molded by insulating plastic.

[0029] The lower shell 1 is the bottom structure of the insulating housing, typically made of plastic or other insulating materials. It supports the internal components of the shunt module and provides electrical insulation. The upper shell 2 is the top structure of the insulating housing module. Together with the lower shell 1, it encloses the entire shunt module and protects the internal components from the external environment. Sealant is injected between the lower shell 1 and the upper shell 2 to ensure the housing's tightness and prevent moisture, dust, and other contaminants from entering.

[0030] The insulating shell is made of plastic material, which has good insulation properties, is light in weight, and is easy to process and form. The use of plastic material reduces the weight of the shell and the weight of the entire shunt module, making it easy to install and transport. At the same time, it provides good electrical insulation, ensuring the safe operation of the shunt module and preventing electrical failures and short circuits.

[0031] Specifically, such as Figs. 1-3 As shown, the power distribution structure includes a positive copper bus 6 and a negative copper bus 7 fixed between the plug assembly 9 and multiple connectors 12; the positive copper bus 6 and the negative copper bus 7 are the main conductive components in the shunt module, which are responsible for distributing the introduced large current to different parts of the module.

[0032] A signal control board 8, which coordinates current detection and control, is installed in the insulating housing. This board is responsible for monitoring and controlling the flow of current, providing overcurrent protection to reduce safety risks caused by overcurrent heating. It contains sensors, microcontrollers, or other electronic components to monitor parameters such as current and voltage and adjust current distribution accordingly.

[0033] Specifically, such as Fig. 1 and Fig. 3 As shown, the assembly structure includes a step screw 5 and a hook 10. The hook 10 is fixed to the insulating housing by a fixing bolt 11. A hole groove is formed in the insulating housing to fit the step screw 5, and a buffer component is provided in the hole groove.

[0034] Hook 10 secures the shunt module to the external structure, ensuring it does not loosen or shift during operation. Working in conjunction with the external retaining clip, hook 10 enhances the module's stability and security. Fixing bolt 11, a standard or custom bolt used to secure hook 10 to the shunt module, provides the primary connection force between the shunt module and the mounting surface, ensuring its stability and long-term reliability.

[0035] The buffer component is a buffer pad 4, the inner wall of which is formed with a polygonal inner hole for fitting the step screw 5 to pass through, and the outer portion of the buffer pad 4 forms an I-shaped structure, and the buffer pad 4 is fixed inside the hole groove through the inwardly recessed groove of the I-shaped structure.

[0036] The step screw 5 is matched with the buffer pad 4 through a flexible multi-edge inner hole, which allows the shunt module to make small spatial position adjustment when subjected to external force, thereby reducing the impact of external force on the module. The buffer pad 4 has a certain deformation space, which allows the shunt module to make small spatial position adjustment when subjected to external force, without damaging the module or losing electrical connection. The design of the assembly component ensures the stability and reliability of the shunt module under various operating conditions, and the design of the buffer pad 4 and the flexible multi-edge inner hole reduces the stress during installation, improves the durability and life of the module. The design of the step screw 5 and the hook provides flexible installation options, so that the shunt module can adapt to different installation environments and requirements.

[0037] The sealing plug 3 corresponding to the hole slot is arranged on the insulating shell, and the sealing plug 3 is inserted into the hole slot to seal and cover the step screw 5. The main function of the sealing plug 3 is to close the opening part of the shunt module, prevent external moisture, dust, impurities and the like from entering the inside of the module, and protect the internal electrical components from environmental factors. In a humid or water-rich environment, the sealing plug 3 can effectively prevent moisture from entering, avoid electrical short circuit or corrosion problems caused by high humidity, and the sealing plug 3 can prevent dust from accumulating inside the module, reduce the wear and tear of the electrical contact points and the reduction of the insulation performance of the dust. The sealing plug 3 and the hole slot adopt a simple plug-in design, which makes the external maintenance and cleaning of the module more convenient, because the sealing plug 3 can be simply replaced to restore the sealing performance of the module.

[0038] The above description of the embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
