Description

Technical Field

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

[0002] A rectifier bridge is an important electronic component, mainly used to convert alternating current (AC) to direct current (DC). It is widely used in circuits, especially in equipment that requires step-down rectification.

[0003] The rectifier bridge has pins, but the pin distribution is not positioned. During transportation, the pins are easily bent due to stress. Furthermore, when disassembling the rectifier bridge, the solder layer on the four pins needs to be melted before the entire rectifier bridge can be removed. However, since the solder on the bottom layer of the pins can still stick between the pins and the PCB, it is not conducive to disassembling the rectifier bridge. Therefore, we propose a rectifier bridge with a positioning mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rectifier bridge with a positioning mechanism to solve the problems mentioned in the background art, such as the pins being easily bent due to force during the transportation of rectifier bridges, and the need to melt the solder layer on the four pins before disassembling the entire rectifier bridge, which is not conducive to disassembling the rectifier bridge because the solder at the bottom of the pins will stick between the pins and the PCB.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rectifier bridge with a positioning mechanism, comprising a rectifier bridge body, a pin connected to the right side of the rectifier bridge body, a spring connected to the lower part of the rectifier bridge body, a bottom shell connected to the lower end of the spring, a first threaded hole in the middle of the rectifier bridge body, and a second threaded hole in the middle of the bottom shell.

[0006] The bottom shell has a sliding groove on its side and a positioning hole on its upper wall.

[0007] A mounting plate is installed on the right end of the rectifier bridge body. A movable rod passes through the mounting plate. A positioning rod is installed on the left end of the movable rod. A positioning plate is connected to the right end of the movable rod. A protective hole is provided on the positioning plate.

[0008] Preferably, the bottom shell forms an elastic structure with the rectifier bridge body through a spring, and the bottom shell is sleeved on the outside of the rectifier bridge body.

[0009] Preferably, the movable rod slides through the slide groove, and the slide groove has an "L" shaped structure.

[0010] Preferably, the position of the protective hole corresponds one-to-one with the position of the pin, and the inner wall of the protective hole is a rubber pad.

[0011] Preferably, the positioning rod engages with the positioning hole, and the total height of the positioning rod and the moving rod is less than the height of the slide groove.

[0012] Preferably, the positions of the first threaded hole and the second threaded hole are arranged corresponding to each other, and the first threaded hole and the second threaded hole are connected by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The rectifier bridge with positioning mechanism presses the rectifier bridge body into the bottom shell, and moves the moving rod into the slide groove and slides in the slide groove. The positioning plate is moved to the pin end. The spring force is used to lock the positioning rod at the end of the moving rod into the positioning hole to limit the positioning plate. The moving rod and the positioning plate are used to support and position the pin and protect it to prevent it from bending under force.

[0015] (2) When the rectifier bridge with positioning mechanism is disassembled, as the solder layer on the pin melts away, the pin fixing becomes loose. With the spring force, the rectifier bridge body and pin move upward, popping out the rectifier bridge body, making it easy to pull out and disassemble the rectifier bridge body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 The present invention provides the following technical solution: a rectifier bridge with a positioning mechanism, including a rectifier bridge body 1, a pin 2 connected to the right side of the rectifier bridge body 1, a spring 3 connected to the lower part of the rectifier bridge body 1, a bottom shell 4 connected to the lower end of the spring 3, a first threaded hole 12 opened in the middle of the rectifier bridge body 1, and a second threaded hole 13 opened in the middle of the bottom shell 4.

[0024] Furthermore, the bottom shell 4 forms an elastic structure with the rectifier bridge body 1 through the spring 3. The bottom shell 4 is sleeved on the outside of the rectifier bridge body 1. When the rectifier bridge body 1 is disassembled, it can be lifted upward by the elastic force between the bottom shell 4 and the rectifier bridge body 1, making it easy to disassemble.

[0025] Furthermore, the positions of the first threaded hole 12 and the second threaded hole 13 are respectively set to correspond to each other. The first threaded hole 12 and the second threaded hole 13 are connected by bolts, so that the rectifier bridge body 1 can be compressed into the bottom shell 4 and then installed and fixed with bolts.

[0026] A sliding groove 5 is provided on the side of the bottom shell 4, and a positioning hole 6 is provided on the upper wall of the sliding groove 5; an mounting plate 7 is installed on the right end of the rectifier bridge body 1, a moving rod 8 passes through the mounting plate 7, a positioning rod 11 is installed on the left end of the moving rod 8, and a positioning plate 9 is connected to the right end of the moving rod 8, and a protective hole 10 is provided on the positioning plate 9.

[0027] Furthermore, the movable rod 8 slides through the slide groove 5, which has an "L" shaped structure, allowing the movable rod 8 to smoothly move into and within the slide groove 5 to adjust the position of the positioning plate 9.

[0028] Furthermore, the positions of the protective holes 10 correspond one-to-one with the positions of the pins 2. The inner wall of the protective holes 10 is a rubber pad, which allows the protective holes 10 to be fitted onto the outside of the pins 2 one by one to support and protect them.

[0029] Furthermore, the positioning rod 11 engages with the positioning hole 6, and the total height of the positioning rod 11 and the moving rod 8 is less than the height of the slide groove 5, so that the positioning rod 11 and the moving rod 8 can slide smoothly in the slide groove 5. When the positioning rod 11 engages with the positioning hole 6, the position of the moving rod 8 is limited.

[0030] Specifically, the rectifier bridge body 1 can be pressed down, causing the rectifier bridge body 1 to compress and store force on the spring 3. The moving rod 8 moves down with the rectifier bridge body 1 and moves into the slide groove 5 through the slot. The moving rod 8 is then pushed to the right, causing it to slide on the slide groove 5 and the mounting plate 7, thereby pushing the positioning plate 9 to the right until the positioning plate 9 moves to the right end of the pin 2. The pressure on the rectifier bridge body 1 is released, and the spring 3 controls the rectifier bridge body 1 to move up and reset, thereby causing the moving rod 8 to move up and engage the positioning rod 11 installed at the end of the moving rod 8 into the positioning hole 6, thus limiting the position of the moving rod 8 and stabilizing the position of the positioning plate 9. The moving rod 8 and the positioning plate 9 are used to support and position the pin 2 and protect it.

[0031] When installing the rectifier bridge, press down on the rectifier bridge body 1 to move the positioning rod 11 out of the positioning hole 6, and move the moving rod 8 to the left to drive the positioning plate 9 to move to the left, releasing the support positioning of the pin 2. Then, use bolts to engage with the first threaded hole 12 and the second threaded hole 13 to lock the rectifier bridge body 1 and the bottom shell 4 onto the installation equipment, and solder the pin 2. At this time, the spring 3 between the rectifier bridge body 1 and the bottom shell 4 is in a compressed state. When disassembling the rectifier bridge, remove the bolts that fix the rectifier bridge body 1 and the bottom shell 4, melt the solder layer on the pin 2, and the pin 2 will be loosened. With the elastic force of the spring 3, push the rectifier bridge body 1 and the pin 2 upward, popping out the rectifier bridge body 1, making it easy to pull out and disassemble the rectifier bridge body 1. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
