Description

Technical Field

[0001] This utility model relates to the field of power electronics technology, and in particular to a centralized voltage module. Background Technology

[0002] In electrical systems, voltage modules play a crucial role, responsible for the rational distribution, precise control, and effective protection of power. However, traditional voltage module designs often employ a distributed layout. First, this distributed component layout makes the overall structure appear loose, occupying a significant amount of space and hindering the compactness and integration of electrical systems. Second, each component is installed independently, requiring separate wiring and fixing, leading to a cumbersome and complex installation process. Third, the numerous connection lines between components not only increase wiring difficulty but also increase the risk of poor contact and aging wiring. Furthermore, in traditional designs, the operating parts of components such as circuit breakers and sockets are often directly exposed, posing a significant safety hazard as operators may come into direct contact with live parts. Finally, in humid or underwater environments, the waterproof performance of traditional voltage modules often fails to meet requirements. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a centralized voltage module that is compact in structure, comprehensive in function, safe and reliable and easy to maintain.

[0004] To achieve the above objectives, this utility model employs a centralized voltage module comprising a housing, within which a circuit board is provided. The circuit board is respectively connected to a plug, terminals, a circuit breaker assembly, and a socket assembly. The plug is located at one end of the circuit breaker assembly and is electrically connected to the circuit board. The socket assembly is located at the other end of the circuit breaker assembly and is electrically connected to the circuit board. The terminals are located on one side of the circuit breaker assembly and are electrically connected to the circuit board. The circuit breaker assembly is plugged into and electrically connected to the circuit board. A panel is installed on the housing at the corresponding plug position, a terminal cover is installed on the housing at the corresponding terminal position, and a flip cover is installed on the housing at the corresponding circuit breaker assembly position.

[0005] The advantages of the above structure are as follows: by integrating the plug, terminal block, circuit breaker assembly and socket assembly into a single housing, modular and integrated design of electrical components is achieved. The housing is equipped with a panel, terminal cover and flip cover, which facilitates the installation, maintenance and replacement of internal electrical components. The plug, terminal block, circuit breaker assembly and socket assembly are all plugged into the circuit board, achieving a stable connection between electrical components.

[0006] This utility model further comprises at least three circuit breaker assemblies, each assembly including a circuit breaker body and a corresponding operating handle. The circuit breaker body is plugged into and electrically connected to the circuit board, and the operating handle is used to operate the opening and closing state of the corresponding circuit breaker body. By providing at least three sets of circuit breaker assemblies, one or more sets can be flexibly selected according to actual needs to meet the configuration requirements of different electrical systems. The design of the operating handle allows operators to safely and conveniently control the opening and closing state of the circuit breaker body, avoiding the risk of direct contact with live parts and enhancing system safety.

[0007] This utility model further comprises a socket assembly including a socket body mounted on a housing, an upper shell mounted on the socket body, and a top cover mounted on the upper shell. The upper shell contains a female connector, which is connected to the upper shell by screws. The socket body has a through cavity matching the female connector, through which several copper pins extend. The housing has through holes matching the positions of the copper pins. The copper pins pass through the housing and are inserted into a circuit board. The socket body has a keying rod on the inner wall corresponding to the copper pins. The female connector being connected to the upper shell by screws ensures a stable connection between the female connector and the upper shell, reducing poor contact caused by vibration or impact. The copper pins being inserted into the circuit board achieves a reliable electrical connection between the socket assembly and the circuit board, ensuring stable current transmission. The keying rod on the inner wall of the socket corresponding to the copper pins effectively prevents mis-insertion of the plug, ensuring that only a matching plug can be correctly inserted into the socket, thus improving safety.

[0008] This utility model is further configured such that plug clips are installed on both sides of the outer wall of the socket body, and the plug clips are C-shaped. The C-shaped plug clips can tightly wrap around the outside of the plug, providing additional support and fixing force to the plug, preventing the plug from easily falling off or loosening when subjected to external force.

[0009] This utility model is further configured with a snap-fit ​​cavity on the upper shell, wherein a foolproof snap-fit ​​is engaged within the snap-fit ​​cavity. The foolproof snap-fit ​​design effectively prevents users from accidentally inserting or removing the snap-fit ​​during operation.

[0010] This utility model is further configured such that the upper shell and the upper cover are connected by a thread, and a rubber ring is provided inside the upper cover, which is located on the inner side of the threaded connection between the upper shell and the upper cover. By using the rubber ring as a sealing element and placing it on the inner side of the threaded connection between the upper shell and the upper cover, dust, moisture or other impurities can be effectively prevented from entering the socket assembly, thereby protecting the internal electrical components from contamination and corrosion.

[0011] This utility model is further configured such that a first connector is mounted on the terminal cover, and a second connector is mounted on the housing on one side corresponding to the terminal cover. Through the cooperation of the first and second connectors, a stable connection is achieved between the terminal cover and the housing.

[0012] This utility model is further configured such that a grounding bolt is installed on one side of the housing corresponding to the panel. When a fault occurs inside the electrical equipment, such as a short circuit or leakage, the equipment casing may become live. The grounding bolt connects the equipment casing to the earth's potential, ensuring that the casing potential is always zero, thereby preventing electric shock accidents when personnel come into contact with it and effectively protecting personal safety.

[0013] This utility model is further configured with a housing comprising an outer shell and a cover plate disposed on the bottom of the outer shell. The combined design of the outer shell and the cover plate makes the overall structure of the housing more complete and stable.

[0014] This utility model is further configured such that both the first and second connectors are waterproof joints. Waterproof joints have excellent waterproof performance, effectively preventing moisture from entering the equipment and protecting internal electrical components from damage caused by moisture, corrosion, etc. Attached Figure Description
