Description

Technical Field

[0001] The present invention relates to the technical field of rectifier bridge installation, and specifically to a rectifier bridge installation device with convenient use. Background Technique

[0002] The rectifier bridge belongs to a common electronic component. Generally, it has a large inductive load, so there will be no current interruption during operation. This enables the rectifier bridge to be widely used in the conversion from alternating current to direct current. When installing the rectifier bridge, the pins are usually welded to the main board, and then the rectifier bridge is fixed to the heat sink through bolts.

[0003] However, in actual use of the prior art, since the rectifier bridge is generally vertically installed on the main board, when the rectifier bridge needs to be installed on the heat sink through bolts, the bolts must be tightened from both ends of the rectifier bridge. However, usually there are many other various electronic components on the main board, and damage may be caused to other electronic components during the process of tightening the bolts in the rectifier bridge. This makes it inconvenient to tighten the bolts in the rectifier bridge. When the rectifier bridge and the heat sink are installed by some other plugging methods, the connection will be loose, resulting in the thermal conductive silicone behind the rectifier bridge not being able to fit tightly with the heat sink, affecting the heat dissipation of the rectifier bridge. At the same time, there is more than one rectifier bridge on some main boards, and they are of different sizes, which is not convenient to install with the heat sink at the same time.

[0034] The rectifier bridge assembly includes a rectifier bridge body 201.

[0036] The adsorption installation positioning component includes a magnet column 301, and the magnet column 301 is movably connected to the inner wall of the installation hole 204. One end of the magnet column 301 away from the vertical heat conducting plate 101 is an arc structure, and the maximum diameter of the end of the magnet column 301 away from the vertical heat conducting plate 101 is greater than the diameter of the middle part of the magnet column 301. The diameter of the middle part of the magnet column 301 is adapted to the inner diameter of the inner wall of the installation hole 204.

Two installation grooves 305 are opened at one end of the vertical heat conducting plate 101 corresponding to the locking column 304, and the surface of the locking column 304 is movably connected to the inner wall of the installation groove 305. The number of the installation grooves 305 is two, and the two installation grooves 305 are arranged vertically up and down. A magnet plate 306 is fixedly embedded in the middle of the end of the vertical heat conducting plate 101 away from the rectifier bridge body 201, and the magnet plate 306 is located between the two installation grooves 305. According to the different sizes of the rectifier bridge body 201, the two locking columns 304 can be divided into multiple combination modes, that is, both of the two locking columns 304 are located on the inner wall of the top installation groove 305, the two locking columns 304 are respectively located on the inner walls of the upper and lower installation grooves 305, and both of the two locking columns 304 are located on the inner wall of the bottom installation groove 305. Thus, through the adsorption installation positioning component, the positioning installation of the rectifier bridge bodies 201 with different sizes can be completed, which is convenient for simultaneously locking and installing a plurality of rectifier bridge bodies 201 with the vertical heat conducting plate 101.

[0038] The locking assembly includes a threaded column 401 which is rotatably connected to the middle of the horizontal heat conducting plate 102 and the mounting base plate 104. The threaded column 401 respectively passes through and extends to the upper and lower ends of the horizontal heat conducting plate 102 and the mounting base plate 104 in an active manner. Two threaded tubes 402 are respectively threadedly connected to the surface of the threaded column 401. The thread directions of the surface of the threaded column 401 corresponding to the two threaded tubes 402 are opposite. A movable plate 403 is fixedly installed on the surface of the threaded tube 402. A rotating groove 404 is formed at one end of the movable plate 403 corresponding to the locking column 304. A clamping driving plate 405 is rotatably arranged on the inner wall of the rotating groove 404. One end of the clamping driving plate 405 corresponding to the locking column 304 is of an arc-shaped structure. The surfaces of the arc-shaped structure of the clamping driving plate 405 and the surface of the locking column 304 are both roughened. Spring pieces 406 are fixedly installed at one ends of the two clamping driving plates 405 away from the vertical heat conducting plate 101.

[0039] Pin shafts are respectively fixedly installed at both ends of the clamping driving plate 405, and the pin shafts are rotatably connected to the inner wall of the rotating groove 404. Two auxiliary clamping plates 407 are fixedly arranged at one end of the vertical heat conducting plate 101 away from the rectifier bridge body 201. The bottom of the auxiliary clamping plate 407 at the top is horizontally coplanar with the plane where the top of the mounting groove 305 at the top is located, and the top of the auxiliary clamping plate 407 at the bottom is horizontally coplanar with the plane where the bottom of the mounting groove 305 at the bottom is located. The two movable plates 403 are both located between the two auxiliary clamping plates 407. The threaded column 401 passes through and extends to the upper and lower ends of the auxiliary clamping plate 407 in an active manner. A second fixing gasket 408 is fixedly installed on the surface of the threaded column 401 corresponding to the position between the bottom auxiliary clamping plate 407 and the mounting base plate 104. A driving turning head 409 is fixedly installed at the top of the threaded column 401. One end of the auxiliary clamping plate 407 corresponding to the mounting groove 305 is of an arc-shaped structure, and the arc-shaped structures of the auxiliary clamping plate 407 and one end of the auxiliary clamping plate 407 corresponding to the locking column 304 are both smoothly arranged.

[0040] Auxiliary positioning components are provided at both ends of the vertical heat conducting plate 101. The auxiliary positioning components include guide posts 501, and the guide posts 501 are fixedly installed at one end of the opposite surfaces of the horizontal heat conducting plate 102 and the mounting base plate 104. The guide posts 501 fixedly penetrate and extend to the upper and lower ends of the auxiliary clamping plate 407. One end of the movable plate 403 corresponding to the position of the guide post 501 is fixedly installed with a guide tube 502, and the guide tube 502 is movably connected to the surface of the guide post 501. A positioning post 503 is fixedly installed on the surface of the guide tube 502 at the bottom. A positioning hole 504 is opened in the middle of the mounting base plate 104 corresponding to the position of the positioning post 503. By providing the guide posts 501 and the guide tubes 502, the up and down movement of the movable plate 403 can be guided. When a locking operation is performed and the movable plate 403 at the bottom is driven to move downward, the movable plate 403 will drive the guide tube 502 at the bottom to move downward. Furthermore, the guide tube 502 at the bottom will pass through the positioning hole 504 through the positioning post 503 and be inserted into the reserved hole on the main board, so that the device is firmly installed.

[0041] Working principle: When in use, one end of the magnet column 301 of the invention is inserted into the inner wall of the mounting hole 204 first. Since the diameter of the middle part of the magnet column 301 is adapted to the inner diameter of the inner wall of the mounting hole 204, the magnet column 301 is not easily detached from the inner wall of the mounting hole 204. The space reserved during the welding of the rectifier bridge body 201 is sufficient to place the rotating arm 303 and the locking column 304, that is, the presence of the rotating arm 303 and the locking column 304 does not affect the welding of the pin 203. Then, the pin 203 is welded at the corresponding position of the main board. At this time, the rectifier bridge body 201 is in a vertical state. The vertical heat conducting plate 101 is moved to one end position of the rectifier bridge body 201, and the vertical heat conducting plate 101 is located at the end with a smaller diameter of the magnet column 301. At the same time, the vertical heat conducting plate 101 is placed at the position of the reserved hole for the vertical heat conducting plate 101 on the main board, that is, the positions of the threaded column 401 and the positioning column 503 correspond to the positions of the reserved holes on the main board. At this time, under the action of magnetic attraction between the magnet plate 306 and the magnet column 301, the magnet column 301 drives the rectifier bridge body 201 to tend to fit on the surface of the vertical heat conducting plate 101 through the first fixing gasket 302. At this time, according to the required shape and size of the rectifier bridge body 201, the rotating arm 303 is rotated with the magnet column 301 as the rotation axis, and the two rotating arms 303 drive the locking column 304 to be placed inside the mounting groove 305. At the same time, the magnet column 301 cooperates with the first fixing gasket 302 to drive the rectifier bridge body 201 to approach one end of the vertical heat conducting plate 101. At this time, the positioning installation between the rectifier bridge body 201 and the vertical heat conducting plate 101 is completed. Then, the positioning installation between the rectifier bridge body 201 and the vertical heat conducting plate 101 at other positions can be carried out. When all the rectifier bridge bodies 201 are respectively completed with the positioning installation with the vertical heat conducting plate 101 through the adsorption installation positioning assembly, at this time, a tool is used to drive the driving turning head 409 to rotate, and the driving turning head 409 drives the threaded column 401 to rotate. Furthermore, the threaded column 401 drives the two threaded tubes 402 to move away from each other, and the threaded tubes 402 drive the two movable plates 403 to move away from each other. Furthermore, the movable plates 403 drive the clamping driving plate 405 to move towards the position of the locking column 304. Since the clamping driving plate 405 is rotatably connected to the inner wall of the rotating groove 404, when the clamping driving plate 405 clamps the locking column 304 in cooperation with the auxiliary clamping plate 407, under the continuous driving action of the movable plate 403, the clamping driving plate 405 will rotate on the inner wall of the rotating groove 404. At the same time, since the surfaces of the arc-shaped structure of the clamping driving plate 405 and the surface of the locking column 304 are both roughened, and the arc-shaped structures of the auxiliary clamping plate 407 and the ends corresponding to the locking column 304 position of the auxiliary clamping plate 407 are respectively rounded, the clamping driving plate 405 will drive the locking column 304 to move towards one end of the vertical heat conducting plate 101.Furthermore, the locking post 304 cooperates with the rotating arm 303, the first fixing gasket 302 and the magnet post 301 to drive the rectifier bridge body 201 to closely fit on the surface of the vertical heat conducting plate 101, and the heat dissipation silica gel 202 forms a closely fitting relationship with the vertical heat conducting plate 101. Since the driving turning head 409 is located at the top of the horizontal heat conducting plate 102, when operating to lock the rectifier bridge body 201 on the surface of the vertical heat conducting plate 101, the tool is used to operate on the driving turning head 409 vertically, so that other electronic components on the main board will not be damaged. By setting the spring piece 406, the relative rotation of the two clamping driving plates 405 can be buffered. At the same time, when the two movable plates 403 approach each other, the spring piece 406 can make the two clamping driving plates 405 return to the initial state. And when the driving turning head 409 drives the threaded column 401 to rotate, the threaded column 401 will be threadedly connected with the reserved hole on the main board, so that the threaded column 401 cooperates with the second fixing gasket 408 to firmly install the whole device above the main board.
