Description

Technical Field

[0001] This utility model relates to the field of rectifier bridge technology, and in particular to a novel rectifier bridge. Background Technology

[0002] A rectifier bridge is a key electronic component that converts alternating current (AC) to direct current (DC), and it is widely used in power supply equipment, industrial control, and home appliances. A traditional rectifier bridge typically consists of a base, a rectifier chip, and electrode plates, which are fixed together using a soldering process. Its core function relies on stable conduction and effective heat dissipation between the rectifier chip and the electrode plates to ensure the reliability and durability of the device during long-term operation.

[0003] However, existing rectifier bridges have significant shortcomings in structural design and installation processes. Firstly, traditional electrode plates often employ a straight-plate design, relying on soldering for connection to external circuits. This results in cumbersome installation steps and limited contact area, making them susceptible to decreased conductivity or localized overheating due to poor soldering. Secondly, the lack of a precise positioning structure between the rectifier module and the base case makes misalignment during assembly prone to occur, affecting heat dissipation efficiency and overall stability. Furthermore, traditional soldering processes hinder rapid assembly and disassembly, making later maintenance or replacement difficult, and the high temperatures during soldering can cause thermal damage to the rectifier chip. Utility Model Content

[0004] This invention provides a rectifier bridge with optimized structure, convenient installation, and efficient heat dissipation.

[0005] The technical solution adopted by this utility model is as follows: a novel rectifier bridge, including a bottom shell, a cover plate disposed on the top of the bottom shell, and a rectifier module installed inside the bottom shell. The rectifier module includes a base plate, a rectifier chip mounted on the base plate, and an electrode sheet welded to the base plate and electrically connected to the rectifier chip. The electrode sheet is L-shaped and passes through the cover plate.

[0006] As a further improvement of this utility model, a plurality of positioning blocks are fixedly connected to the inner wall of the bottom shell, and positioning grooves that cooperate with the positioning blocks are provided on all four sides of the bottom plate.

[0007] As a further improvement of this utility model, the cover plate is fixedly snapped onto the top of the bottom shell, and the cover plate is provided with multiple through holes for the electrode plates to pass through.

[0008] As a further improvement of this utility model, the top wall of the electrode sheet extends downward with a protrusion and a mounting hole is provided at the top wall of the electrode sheet and the protrusion.

[0009] As a further improvement of this utility model, the inner surface of the mounting hole is provided with mounting threads.

[0010] The beneficial effects of this utility model are as follows: By adopting an L-shaped electrode plate and a mounting hole with mounting threads, combined with the precise matching of the bottom shell positioning block and the bottom plate positioning groove, and the snap-fit ​​structure of the cover plate, this utility model significantly improves the ease of installation, contact area and heat dissipation efficiency of the rectifier bridge, while ensuring the accuracy of assembly and the reliability of electrical connection, thereby optimizing the overall performance stability and maintenance convenience of the rectifier bridge.

[0015] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0017] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] This utility model provides the following: Figure 1-3 The novel rectifier bridge shown includes a base shell 1, a cover plate 2 disposed on the top of the base shell 1, and a rectifier module installed inside the base shell 1. The rectifier module includes a base plate 3, a rectifier chip 4 mounted on the base plate 3, and an electrode plate 5 soldered to the base plate 3 and electrically connected to the rectifier chip 4. The electrode plate 5 is L-shaped and passes through the cover plate 2.

[0019] like Figure 2 As shown, in this utility model, multiple positioning blocks 7 are fixedly connected to the inner wall of the bottom shell 1, and positioning grooves 8 that cooperate with the positioning blocks 7 are provided on all four sides of the bottom plate 3. In the actual installation process, the cooperation between the positioning blocks 7 and the positioning grooves 8 can quickly and accurately determine the position of the rectifier module in the bottom shell 1, avoid the offset during installation, and greatly improve the accuracy of assembly.

[0020] like Figure 2 As shown, in this utility model, the cover plate 2 is fixedly snapped onto the top of the bottom shell 1. The cover plate 2 is provided with multiple through holes 9 for the electrode plates 5 to pass through, which makes the installation and disassembly of the cover plate 2 easier, without the need for complicated tools or cumbersome operations, thus improving the efficiency of later maintenance and replacement of parts.

[0021] like Figure 2 and Figure 3 As shown, in this utility model, the top wall of the electrode sheet 5 extends downward with a protrusion, and a mounting hole 6 is provided at the top wall and the protrusion of the electrode sheet 5. The inner surface of the mounting hole 6 is provided with a mounting thread, so that when the electrode sheet 5 is connected to the external circuit, it can be fastened by screws or other connecting parts passing through the mounting hole 6. Compared with the traditional welding method, it not only increases the contact area and improves the conductivity, but also effectively avoids various problems caused by poor welding. At the same time, it facilitates the installation and disassembly of the electrode sheet and further enhances the maintenance convenience of the rectifier bridge.

[0022] Working Principle: In practical implementation, the rectifier chip 4 is first installed on the base plate 3. Then, the electrode plate 5 is passed through the through hole 9 on the cover plate 2 and soldered to the base plate 3, electrically connected to the rectifier chip 4, completing the initial assembly of the rectifier module. Next, the assembled rectifier module is placed into the bottom shell 1, aligning the positioning grooves 8 on the four sides of the base plate 3 with the positioning blocks 7 on the inner sidewall of the bottom shell 1 to ensure accurate installation of the rectifier module. Then, the cover plate 2 is snapped onto the top of the bottom shell 1. Finally, screws and other connectors are used to pass through the mounting holes 6 on the top wall and protrusions of the electrode plate 5 to securely connect the electrode plate 5 to the external circuit. In this way, AC power enters the rectifier bridge, is converted into DC power by the rectifier chip 4, and is then transmitted to the external circuit through the electrode plate 5, realizing the function of the rectifier bridge in converting AC power to DC power. Moreover, thanks to the optimized structural design, the efficiency, stability, and reliability of the rectifier bridge during operation are ensured.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
