Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer rectifier technology, specifically a rectifier that is easy to adjust. Background Technology
[0002] Traditional rectifiers have significant design flaws in terms of adjustment and maintenance. First, they generally use miniature potentiometers for parameter adjustment, which requires tools such as screwdrivers and makes precise adjustment difficult in the confined space of the chassis, especially posing a risk of electric shock when the equipment is powered on. Second, the heat sink and circuit board are often fixed with bolts, and this rigid connection requires complete disassembly of the heat sink to access the underlying components during maintenance, greatly increasing the difficulty and time cost of maintenance.
[0003] The existing patent announcement number CN223121060U discloses a transformer rectifier that is easy to adjust, including a rectifier body and "a bracket set at the bottom of the rectifier body, a connecting block fixed on one side of the rectifier body; a threaded rod set on the inner wall of the connecting block and installed horizontally, a snap-fit block threadedly connected to the outer side of the threaded rod, and a push rod fixed at one end of the threaded rod." This utility model can easily snap the rectifier body to the bracket by setting a snap-fit mechanism, thereby facilitating the disassembly and installation of the rectifier and improving the installation efficiency of the main body. However, it does not have the function of internal adjustment and quick disassembly, and repeated disassembly and assembly can easily cause thread stripping or PCB board deformation. The fixed design of its internal output terminals results in extremely poor wiring flexibility. When it is necessary to connect cables of different wire diameters, it is impossible to adjust the terminal spacing according to the actual space requirements. In multi-output applications, it is easy to cause cables to cross and entangle, which affects heat dissipation and increases the risk of short circuit. This design that lacks modular consideration greatly reduces the adaptability of the equipment under complex working conditions.
[0004] Based on this, a rectifier that is easy to adjust is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0013] In one alternative: a mounting plate is fixedly connected to the lower surface of the rectifier box, and the mounting plate has several mounting holes around its perimeter.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through its modular mechanical design and installation components, effectively improves the adjustability and maintenance efficiency of the rectifier. The sliding cooperation between the mounting rail and the T-block allows for free adjustment of the terminal spacing, adapting to the wiring needs of cables of different diameters and reducing the risk of short circuits caused by cable tangling. The spring and limit post linkage design of the limiting component allows for single-handed operation to lock the terminal position, effectively improving the rectifier's adjustment performance.

[0021] 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.
[0022] In one embodiment, such as Figures 1-5 As shown, a rectifier that is easy to adjust includes a rectifier box 1. An installation component is provided in the middle of the rectifier box 1.

Several terminals 17 are slidably arranged on the upper surface of the mounting rail 13. A T-shaped block 18 is fixedly connected to the lower center of each terminal 17. The T-shaped blocks 18 are slidably connected to the inner side of the T-shaped groove 15. Each terminal 17 is provided with a limiting component on one side and is fixed above the mounting rail 13 by the limiting component; In this embodiment, the rectifier box 1 serves as the main frame. The mounting guide rail 13 inside it is slidably mounted with the T-shaped block 18 at the bottom of the terminal 17 through the T-shaped groove 15. The user can move the terminal 17 laterally along the guide rail to the target position. The baffle 14 prevents the terminal 17 from slipping off, and the mounting port 16 facilitates the initial insertion of the T-shaped block 18. The limiting component pushes the limiting post 22 into the limiting hole 24 through the preload of the spring 21 to fix the terminal 17.
[0023] In one embodiment, such as Figure 5 As shown, the limiting assembly includes a limiting seat 19, on which a pair of extrusion plates 20 are symmetrically arranged. The lower end of the extrusion plate 20 penetrates the upper surface of the limiting seat 19 and is slidably disposed on the inner side of both ends of the limiting seat 19. Several springs 21 are fixedly connected to one side of the lower end of the extrusion plate 20. One end of the spring 21 is fixedly connected to the inner side of the limiting seat 19. A limiting post 22 is fixedly connected to the other side of the lower end of the extrusion plate 20. One end of the limiting post 22 is slidably connected to one side of the lower end of the limiting seat 19. The limiting seat 19 is slidably connected to the T-slot 15 through a slider 23. When the extrusion plates 20 on both sides are pressed, the springs 21 are compressed, causing the limiting post 22 to exit the limiting hole 24 and unlock. After being released, the springs 21 return to their original position, and the limiting post 22 re-enters the limiting hole 24. The symmetrically designed extrusion plates 20 ensure balanced force distribution.
[0024] In one embodiment, such as Figure 5 As shown, a slider 23 is fixedly connected to the lower middle part of the limiting seat 19. The slider 23 is slidably connected to the inner side of the T-shaped groove 15. The limiting seat 19 is slidably set by the slider 23 and the T-shaped groove 15.
[0025] In one embodiment, such as Figure 4 As shown, the mounting guide rail 13 has several limiting holes 24 arrayed on both sides. The limiting post 22 is snapped into the adjacent limiting hole 24. The spring 21 is compressed to make the limiting post 22 exit the limiting hole 24 and unlock. After being released, the spring 21 returns to its original position and the limiting post 22 re-enters the limiting hole 24. The symmetrically designed extrusion plate 20 ensures balanced force.
[0026] In one embodiment, such as Figure 3 As shown, the heat dissipation assembly includes a mounting base 7, which is fixedly connected to one side of the rectifier box 1. A fixing plate 8 is provided above the mounting base 7. Several limiting grooves 10 are correspondingly opened on adjacent sides of the mounting base 7 and the fixing plate 8. Several heat dissipation fins 11 are arrayed inside the limiting grooves 10. An anti-sliding block 12 is fixedly connected to one side of each heat dissipation fin 11. The other end of each heat dissipation fin 11 passes through an adjacent heat dissipation hole 6 and is located outside the rectifier box 1. It is positioned in the limiting groove 10 by the blocking of the anti-sliding block 12 and cooperates with a terminal 17 on one side to prevent the heat dissipation fin 11 from sliding, forming a vertical fixation. The fastening bolts 9 press the fixing plate 8 onto the mounting base 7, so that the heat dissipation fins 11 are clamped and fixed. The exposed part of the heat dissipation fin 11 exchanges heat with the external air through the heat dissipation hole 6.
[0027] In one embodiment, such as Figure 3 As shown, the upper surface of the fixing plate 8 is provided with fastening bolts 9 and is fixed to the mounting base 7 by means of fastening bolts 9. The fastening bolts 9 are used to fix the fixing plate 8 and the mounting base 7.

[0030] The above embodiment discloses a rectifier that is easy to adjust. The rectifier box 1 is fixed by the mounting plate 4 and the mounting hole 5. The rectifier box 1 then serves as the main frame. The mounting guide rail 13 inside it is slidably installed with the T-shaped block 18 at the bottom of the terminal 17 through the T-shaped groove 15. The user can move the terminal 17 laterally to the target position along the guide rail. The baffle 14 prevents the terminal 17 from slipping off, and the mounting port 16 facilitates the initial insertion of the T-shaped block 18. The limiting component pushes the limiting post 22 into the limiting hole 24 by the pre-tightening force of the spring 21 to fix the terminal 17. Then, the anti-sliding block 12 is set in the limiting groove 10 and cooperates with the terminal 17 on one side to prevent the heat sink fin 11 from sliding, forming a vertical fixation. The fastening bolt 9 presses the fixing plate 8 onto the mounting base 7, so that the heat sink fin 11 is clamped and fixed. The exposed part of the heat sink fin 11 exchanges heat with the outside air through the heat dissipation hole 6. Moreover, the number of heat sink fins 11 can be flexibly increased or decreased according to the number of terminals.
