Description

Technical Field

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

[0002] The rectifier bridge is the core component that converts alternating current (AC) to direct current (DC). Most existing rectifier bridges are integrated structures, where the rectifier diodes, electrode leads, and insulating shell are fixed as an inseparable whole through injection molding or encapsulation. However, this integrated encapsulation causes the heat dissipation paths of each rectifier diode to overlap, making it easy for heat to accumulate inside. This leads to increased component operating temperature, poor heat dissipation efficiency, and reduced lifespan. Furthermore, when a single rectifier diode fails, the entire rectifier bridge must be replaced, making it impossible to replace the faulty component individually. This can easily lead to resource waste and high maintenance costs. Therefore, we propose a split rectifier bridge structure. Utility Model Content

[0017] like Figure 1-4As shown, the split rectifier bridge structure proposed in this utility model includes a split base assembly 1, a rectifier diode assembly 2, and a split top cover assembly 3. The split base assembly 1 includes a base body 11, which is made of insulating and high-temperature resistant material. Multiple sets of heat dissipation holes are opened at the bottom of the base body 11. The split top cover assembly 3 includes a top cover body 31, which is made of heat-dissipating metal material. Multiple sets of component slots 6 are correspondingly opened on both the base body 11 and the top cover body 31. A heat-conducting layer 7 is provided in each component slot 6, and the mounting end of the heat-conducting layer 7 is fixedly connected to the inner wall of the component slot 6. Multiple sets of mounting plates 12 are provided inside the base body 11, and heat dissipation blocks are provided at the corresponding positions of each mounting plate 12 inside the top cover body 31. 32. The mounting end of the mounting plate 12 is installed correspondingly to the inner wall of the heat-conducting layer 7 in the base body 11, and the mounting end of the mounting plate 12 is fixedly connected to the inner wall of the heat-conducting layer 7 in the base body 11. The mounting end of the heat dissipation block 32 is installed correspondingly to the inner wall of the heat-conducting layer 7 in the upper cover body 31, and the mounting end of the heat dissipation block 32 is fixedly connected to the inner wall of the heat-conducting layer 7 in the upper cover body 31. The setting of the heat-conducting layer 7 can enable the heat on the mounting plate 12 and the heat dissipation block 32 to be quickly conducted, thereby ensuring the long-term stable operation of the rectifier bridge as a whole. A thermally conductive silicone grease layer 33 is provided on one side of the heat dissipation block 32, and the mounting end of the thermally conductive silicone grease layer 33 is fixedly connected to one side of the heat dissipation block 32. The setting of the thermally conductive silicone grease layer 33 can enable the separate upper cover assembly 3 and the separate base assembly to be connected. When assembled, the rectifier diode body 21 and the heat sink 32 fit together more closely, eliminating contact gaps. Each set of base bodies 11 has fastening bolts 13 at four corner positions. Mounting holes are provided at each of the four corner positions on the base body 11. Threaded holes are provided at each of the four corner positions on one side of the top cover body 31. The mounting ends of the fastening bolts 13 are installed corresponding to the mounting holes, and are rotatably connected to the inner wall of the mounting holes. The top ends of the fastening bolts 13 are installed corresponding to the bolt holes, and are threadedly connected to the inner wall of the bolt holes. The fastening bolts 13 ensure a secure fit when the base body 11 and the top cover body 31 are assembled. Each set of fastening bolts 13 has threaded holes at each of the four corner positions on one side of the base body 11. Each body 11 is equipped with a positioning post 14. The mounting end of the positioning post 14 is installed corresponding to one side of the base body 11 and is fixedly connected to one side of the base body 11. The lower end of the positioning post 14 is polygonal. The polygonal shape of the positioning post 14 can better limit the position of the upper cover body 31 when it is installed with the base body 11, thereby ensuring the stability of the upper cover body 31 when it is in the equipped state. The top of the positioning post 14 is columnar. A positioning hole is opened on the upper cover body 31 corresponding to the position of each group of positioning posts 14. The top of the positioning post 14 is installed corresponding to the positioning hole and is slidably connected to the positioning hole. The positioning post 14 can position the upper cover body 31.Multiple sets of heat dissipation fins 34 are provided on one side of the upper part of the upper cover body 31. These fins are evenly and vertically arranged along the upper side of the upper cover body 31, and their mounting ends are fixedly connected to one side of the upper cover body 31.

The combined use of the separate base assembly 1 and the separate upper cover assembly 3 forms a multi-path heat dissipation structure, optimizing heat dissipation efficiency. The component operating temperature is significantly lower than that of an integrated rectifier bridge, extending its service life. The rectifier diode assembly 2 includes rectifier diode bodies 21 correspondingly disposed within each mounting plate 12. The mounting ends of the rectifier diode bodies 21 are mounted corresponding to one side of the mounting plate 12. Multiple sets of pin holes are formed on the rectifier diode bodies 21, and the mounting ends of the rectifier diode bodies 21 are slidably connected to the pin holes. The rectifier diode bodies 21 can be inserted into one side of the mounting plate 12 through the pin holes. Multiple sets of pin sleeves 22 are provided on both sides of each rectifier diode body 21. The multiple sets of pin sleeves 22 are respectively sleeved outside the pins of the rectifier diode bodies 21, and the mounting ends of the pin sleeves 22 are fixedly connected to the outside of the pins of the rectifier diode bodies 21. Multiple sets of elastic conductive clips 23 are provided inside each set of pin sleeves 22, and the mounting ends of the elastic conductive clips 23 are fixedly connected to the inner wall of the pin sleeve 22. The pin sleeve 22 has a hollow cylindrical structure, and the multiple sets of elastic conductive clips 23 are arranged along the inner wall of the pin sleeve 22. The mounting plate 12 is arranged at intervals, with electrode connection posts 24 on both sides of the rectifier diode body 21. The mounting end of the electrode connection post 24 is fixedly connected to one side of the rectifier diode body 21. The surface of the electrode connection post 24 is provided with a gold-plated conductive layer. When the pin sleeve 22 is engaged with the electrode connection post 24, the elastic conductive clip 23 tightly wraps the outer wall of the electrode connection post 24. The pin sleeve 22 and the corresponding electrode connection post 24 are matched and engaged to form an electrical connection. The elastic conductive clip 23 inside the pin sleeve 22 cooperates with the gold-plated layer of the electrode connection post 24 to ensure reliable electrical connection and avoid poor contact caused by vibration or temperature change. The rectifier diode assembly 2 is installed in a plug-in form on one side above the mounting plate 12 on the split base assembly 1. When a single component is damaged, only the split top cover assembly 3 needs to be disassembled and the faulty component replaced, without the need for overall replacement, which greatly reduces maintenance costs. A sealing ring 4 is fitted around the outer ring of the base body 11 and the upper cover body 31 on their adjacent sides. Assembly grooves are formed on the outer periphery of both the base body 11 and the upper cover body 31 on their adjacent sides. The inner ring of the sealing ring 4 is installed correspondingly to the inner wall of the assembly groove, and the inner ring of the sealing ring 4 fits tightly against the inner wall of the assembly groove. The sealing ring 4 can seal the gap between the split base assembly 1 and the split upper cover assembly 3 when they are assembled, thereby preventing external rainwater from entering the rectifier bridge and damaging the rectifier diode assembly 2. A latching assembly 5 is provided around the base body 11 and the upper cover body 31. The latching assembly 5 includes... The hook 51 is provided on one side of the base body 11 and the seat 52 is provided on one side of the top cover body 31.

When the base body 11 and the top cover body 31 are in a conversion state, the hook 51 and the seat 52 are locked together. The setting of multiple sets of locking components 5 can further improve the stability of the split base component 1 and the split top cover component 3 when they are in an assembled state.

[0018] In this embodiment, the operator first assembles the heat-conducting layer 7 into the component slots 6 of the base body 11 and the upper cover body 31, then installs the mounting plate 12 onto the inner wall of the heat-conducting layer 7 on the base body 11, and then inserts the rectifier diode assembly 2 into the mounting plate 12. At this time, it is ensured that the pin sleeve 22 and the electrode connection post 24 are engaged, thereby completing the assembly of the rectifier diode assembly 2. Then, the operator assembles the heat dissipation block 32 with the thermal grease layer 33 into the heat-conducting layer 7 on the upper cover body 31, and then installs the split upper cover assembly 3. The upper side of the split base assembly 1 is installed accordingly, and the positioning post 14 is inserted into the positioning hole on the upper cover body 31. Then the operator presses down the upper cover body 31, so that the card holder 52 is guided by the inclined surface of the card hook 51 and the card hook 51 is locked in the inner side of the card holder 52. At this time, one side of the thermal grease layer 33 is tightly attached to the upper side of the rectifier diode body 21.
