Description

Technical Field

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

[0002] like Figure 7 As shown, currently, the rectifier bridge plate 1 and the insulating bushing 2 are usually riveted together using rivets 8. The operator first pre-installs the rivets 8 in the mounting hole of the rectifier bridge plate 1, then puts the insulating bushing 2 into the mounting hole, and finally uses a riveting tool to complete the riveting and fastening, ensuring that the insulating bushing 2 and the rectifier bridge plate 1 are stably attached and achieve the insulation function.

[0003] The above riveting method not only significantly increases labor costs and consumable costs of rivets 8, but also has many technical problems: low assembly efficiency, reliance on manual or semi-automated operation, and susceptibility to human factors leading to poor assembly consistency; improper pressure control during riveting can easily result in false riveting or over-riveting, and rivets 8 and molds need to be replaced for different product specifications, resulting in poor versatility and high changeover costs. Utility Model Content

[0004] In view of the above-mentioned defects in the existing technology, the present invention provides a rectifier bridge structure, which simplifies the assembly process of the rectifier bridge plate and the insulating bushing, improves the assembly efficiency, and reduces labor costs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A rectifier bridge structure includes a rectifier bridge plate and an insulating bushing. The insulating bushing is provided with a snap-fit ​​structure. The rectifier bridge plate is provided with a mounting hole adapted to the insulating bushing and a snap-fit ​​part that cooperates with the snap-fit ​​structure. The snap-fit ​​structure and the snap-fit ​​part snap together to fix the insulating bushing in the mounting hole.

[0007] The snap-fit ​​structure includes a connecting seat connected to the side of the insulating bushing, elastic arms protruding along the axial direction of the insulating bushing on opposite sides of the connecting seat, and snap-fits disposed at the ends of the elastic arms.

[0008] The connecting seat is provided with a mounting groove that is adapted to the snap-fit ​​part, and the two elastic arms are disposed on the groove wall of the mounting groove.

[0009] The buckle is a buckle hole, and the two opposite sides of the buckle part are respectively provided with a first buckle protrusion that cooperates with the buckle hole.

[0010] Both the card hole and the first card protrusion are wedge-shaped.

[0011] The buckle is a second buckle protrusion. The buckle part is provided with a buckle surface and a through hole for the two elastic arms to pass through. The through hole passes through the buckle surface, and the two second buckles are buckled on the buckle surface after passing through the through hole.

[0012] There are two through holes, and each of the two through holes corresponds to one of the two elastic arms.

[0013] A positioning structure is provided between the rectifier bridge plate and the connecting seat.

[0014] The positioning structure includes a positioning hole disposed on the rectifier bridge electrode plate and a positioning post disposed on the connector and adapted to the positioning hole.

[0015] The connecting seat is connected to multiple insulating bushings.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] The rectifier bridge structure provided by this utility model features a snap-fit ​​structure on the insulating bushing and a snap-fit ​​part on the rectifier bridge plate that mates with the snap-fit ​​structure. Since the snap-fit ​​structure is a highly efficient connection method, it achieves self-locking between the insulating bushing and the rectifier bridge plate without the need for additional fasteners. Furthermore, the assembly operation is simple, simplifying the assembly process, significantly shortening the assembly time, greatly improving assembly efficiency, and effectively reducing labor costs. Simultaneously, the snap-fit ​​structure also has the advantage of easy disassembly and maintenance. Therefore, the rectifier bridge structure provided by this utility model simplifies the assembly process between the rectifier bridge plate and the insulating bushing, improves assembly efficiency, and reduces labor costs.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 3 As shown, this embodiment discloses a rectifier bridge structure, including a rectifier bridge plate 1 and an insulating bushing 2. The insulating bushing 2 is provided with a snap-fit ​​structure. The rectifier bridge plate 1 is provided with a mounting hole 11 that matches the insulating bushing 2 and a snap-fit ​​part 12 that cooperates with the snap-fit ​​structure. The snap-fit ​​structure and the snap-fit ​​part 12 snap-fit ​​together to fix the insulating bushing 2 in the mounting hole 11.

[0029] In this embodiment, the rectifier bridge structure features a snap-fit ​​structure on the insulating bushing 2 and a snap-fit ​​part 12 on the rectifier bridge plate 1 that mates with the snap-fit ​​structure. Since the snap-fit ​​structure is a highly efficient connection method, it achieves self-locking between the insulating bushing 2 and the rectifier bridge plate 1 without the need for additional fasteners. Furthermore, the assembly operation is simple, simplifying the assembly process, significantly shortening the assembly time, greatly improving assembly efficiency, and effectively reducing labor costs. Simultaneously, the snap-fit ​​structure also has the advantage of easy disassembly and maintenance. Therefore, this rectifier bridge structure simplifies the assembly process between the rectifier bridge plate 1 and the insulating bushing 2, improves assembly efficiency, and reduces labor costs.

[0030] The snap-fit ​​structure in this embodiment includes a connecting seat 3 connected to the side of the insulating bushing 2, elastic arms 4 protruding along the axial direction of the insulating bushing 2 on opposite sides of the connecting seat 3, and snap-fits at the ends of the elastic arms 4. By placing the snap-fit ​​structure on the side of the insulating bushing 2, the assembly of the insulating bushing 2 and the rectifier bridge plate 1 is not affected, while ensuring the structural strength and assembly efficiency of the connection, and providing the possibility for subsequent maintenance.

[0031] In this embodiment, the connector 3 is provided with a mounting groove 31 that matches the snap-fit ​​part 12, and two elastic arms 4 are provided on the groove wall of the mounting groove 31. By providing the mounting groove 31, the connector 3 and the snap-fit ​​part 12 are precisely engaged, ensuring a clean and smooth appearance of the rectifier bridge structure.

[0032] In this embodiment, the buckle is a buckle hole 5, and the two opposite sides of the buckle part 12 are respectively provided with a first buckle protrusion 13 that cooperates with the buckle hole 5.

[0033] To ensure ease of assembly, reliable connection, and structural durability of the card hole 5 and the first card protrusion 13, this embodiment preferably features a wedge shape for both the card hole 5 and the first card protrusion 13.

[0034] In order to improve the assembly accuracy of the rectifier bridge plate 1 and the insulating bushing 2, a positioning structure is provided between the rectifier bridge plate 1 and the connecting seat 3 in this embodiment.

[0035] Specifically, the positioning structure includes positioning holes provided on the rectifier bridge plate 1 and positioning posts 6 provided on the connecting seat 3 and adapted to the positioning holes.

[0036] To further improve assembly efficiency, in this embodiment, the connecting seat 3 is preferably connected to multiple insulating bushings 2.

[0037] To further improve the connection strength between the insulating bushing 2 and the snap-fit ​​structure, this embodiment preferably integrates the insulating bushing 2 and the snap-fit ​​structure.

[0038] In this embodiment, during the assembly of the rectifier bridge structure, the positioning post 6 is first aligned with the positioning hole and the insulating bushing 2 is aligned with the mounting hole 11. Then, axial pressing is performed. When the two elastic arms 4 elastically deform and automatically rebound, causing the locking hole 5 to snap onto the first locking protrusion 13, the insulating bushing 2 and the rectifier bridge plate 1 can be fastened in one go without the need for riveting parts and riveting fixtures, which greatly improves the assembly accuracy and assembly efficiency of the rectifier bridge plate 1 and the insulating bushing 2.

[0039] Example 2:

[0040] This embodiment is basically the same as Embodiment 1, except that:

[0041] like Figures 4 to 6 As shown, in this embodiment, the buckle is a second buckle protrusion 7. The buckle part 12 is provided with a buckle surface 15 and a through hole 16 for two elastic arms 4 to pass through. The through hole 16 passes through the buckle surface 15, and the two second buckles 7 are buckled on the buckle surface 15 after passing through the through hole 16.

[0042] To ensure the snap-fit ​​effect, this embodiment preferably provides two through holes 16, with each of the two through holes 16 corresponding to one of the two elastic arms 4.

[0043] To ensure ease of assembly between the second latching protrusion 7 and the latching surface 15, this embodiment preferably features a wedge-shaped second latching protrusion 7, and the second latching protrusion 7 is provided with a beveled surface that has a guiding function.

[0044] In this embodiment, the connecting seat 3 is connected to two insulating bushings 2. The two insulating bushings 2 can achieve precise positioning with the rectifier bridge plate 1. Therefore, in this embodiment, no positioning structure is set between the rectifier bridge plate 1 and the connecting seat 3. This setting further simplifies the structure and reduces production costs. In practical applications, positioning structures can be selected according to actual needs.

[0045] The above details two embodiments of the rectifier bridge structure of this utility model; further embodiments are not described here. In summary, the rectifier bridge structure provided by this utility model simplifies the assembly process of the rectifier bridge plate 1 and the insulating bushing 2, improves assembly efficiency, reduces labor costs, and has good economic benefits.
