Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, and in particular to a heat sink with movable pins. Background Technology

[0002] In the past, power supply products used fixed-pin heatsinks. The position of these fixed pins varied depending on the PCB layout, resulting in multiple part numbers and increasing material control burden. PCB design required consideration of the fixed pin positions and safety clearances, further complicating PCB layout. Specifically, fixed-pin heatsinks required careful consideration of position and safety clearances from the initial PCB layout stage, significantly complicating PCB routing. The fixed-pin positions of heatsinks were determined by the PCB layout, and different pin positions for the same heatsink increased mold costs. Different pin positions necessitated separate part numbers, further increasing material management burden.

[0003] Therefore, it is necessary to provide a heat sink with movable pins, which can unify the materials and move the heat sink fixing pins according to the PCB hole positions, so as to achieve multiple uses of one material. Utility Model Content

[0034] Please see Figures 1-4 As shown, this utility model provides a heat sink with movable pins, including a vertical support plate 1 and a pin plug 4. Multiple heat sinks 2 are fixed on the vertical support plate 1, with gaps between the heat sinks 2. A base plate 3 is provided at the bottom of the vertical support plate 1. The bottom surface of the base plate 3 protrudes downwards to form two relatively spaced strips arranged along the length of the base plate 3. The pin plug 4 includes a vertical plate 401, with pins 402 at its bottom. A lower horizontal plate 403 and an upper horizontal plate 404 are fixed on the same side of the vertical plate 401, spaced apart. A retaining plate 406 is provided on the lower horizontal plate 403, inclined upwards towards the vertical plate 401. A bending plate 405, bent towards the vertical plate 401, is provided on the bottom surface of the upper horizontal plate 404 away from the vertical plate 401. In use, the lower horizontal plate 403 is located below the base plate 3, and the bending plate 405 is located on the top surface of one of the heat sinks 2. The number of pins 402 is two. In use, the bending plate 405 is located on the top surface of the heat sink 2, which is closest to the base plate 3. The movable pins (i.e., pin inserts 4) are assembled onto the heat sink, and their positions on the heat sink 2 are adjusted according to the PCB location. Then, a riveting machine is used to stamp the riveting grooves on the heat sink. To reduce PCB traces, considering pin layout factors, the PCB layout can be performed first, and heat sink pins can be placed in any empty space. This allows for material standardization; the heat sink fixing feet can be moved according to the PCB hole positions, achieving multiple uses from a single material. Multiple uses from a single material reduce additional mold costs caused by differences in fixing foot positions, thus lowering costs.

[0035] In one implementation, the pin plug-in 4 is made of an elastic material and is flexibly mounted on the base plate 3 and the heat sink 2, making installation convenient. Alternatively, the pin plug-in 4 can be fixed to the base plate 3 and the heat sink 2 by riveting or welding. It should be further noted that any other components used to achieve the above effects should fall within the inventive concept of this utility model and should be protected within its scope.

[0036] In one embodiment, the heat sink 2 has multiple grooves on its top surface and multiple hemispherical protrusions on its bottom surface. The hemispherical protrusions are staggered to increase the heat sink area and improve heat dissipation performance. The heat sink can be equipped with a fan to dissipate heat from the heat sink.

[0037] In one embodiment, the heat sink further includes a fixing member 5, which secures the pin insertion plug 4 to the base plate 3 and the heat sink 2. The fixing member 5 is a fastening screw, which is screwed onto the lower horizontal plate 403. Rotating the fastening screw mounts the pin insertion plug 4 onto the base plate 3 and the heat sink 2. Twisting the fastening screw causes it to contact the base plate 3, thereby causing the pin insertion plug 4 to move downwards, pressing the bending plate 405 against the heat sink 2, thus forming a fixed connection.

[0038] Please see Figures 5-7 As shown, in another embodiment, the fixing member 5 includes a housing 501, which is fixed to the lower horizontal plate 403. The housing 501 has a first vertical sliding groove 502 and a first horizontal sliding groove 503 inside. The top of the first vertical sliding groove 502 communicates with the outside, and the first horizontal sliding groove 503 communicates with the first vertical sliding groove 502. A second horizontal sliding groove 504 communicates with the first horizontal sliding groove 503 above it, and a second vertical sliding groove 505 communicates with the second horizontal sliding groove 504 above it. A third vertical sliding groove 506 communicates with the second vertical sliding groove 505 below it, and the third vertical sliding groove 506 communicates with the second horizontal sliding groove 504. A top rod 507 is provided inside the first vertical sliding groove 502, and an elastic rod 508 is provided at the top of the top rod 507. A lever 509 is provided on the outer wall of the rod 507 near the second vertical slide groove 505. A limiting rod 510 is provided in the first horizontal slide groove 503. A stop block 511 is provided on the top of the limiting rod 510. The stop block 511 is located in the second horizontal slide groove 504. A baffle 512 is provided in the second vertical slide groove 505. A stop rod 513 is provided on the bottom surface of the baffle 512. The stop rod 513 is partially located in the third vertical slide groove 506. A lever 514 that cooperates with the lever 509 is provided on the outer wall of the baffle 512 near the top rod 507. A first pull rod 515 and a second pull rod 516 are provided on the outer wall of the housing 501. The first pull rod 515 is connected to the top rod 507, and the second pull rod 516 is connected to the limiting rod 510. Both the baffle 512 and the limiting rod 510 are connected to a return spring. The elastic rod 508 includes an outer rod, the bottom of which is connected to the top rod 507. The top surface of the outer rod is recessed downward to form a groove, and an inner rod is slidably connected in the groove. A spring is fixed at the bottom of the inner rod.

[0039] After adjusting the position of the pin plug 4, push the first pull rod 515 to move the top rod 507 upward. The elastic rod 508 abuts against the base plate 3, causing the bending plate 405 to press against the top surface of the heat sink 2, thus fixing the pin plug 4 to the heat sink. During the upward movement of the top rod 507, the lever 509 contacts the lever 514 and drives it upward. The stop rod 513 releases the limit on the stop block 511, and the second pull rod 516 is pulled, so that the limiting rod 510 is located below the top rod 507, providing support and limiting it. To remove, pull the first pull rod 515 upward and pull the second pull rod 516 to the left. The top rod 507 will automatically move downward under gravity, or pull the first pull rod 515 downward to reset, releasing the fixation of the pin plug 4. Alternatively, a third pull rod can be provided to move the baffle 512. Preferably, a spring is provided to push the baffle 512 downward, pushing the limiting rod 510 towards the top rod 507 (right in the figure). In this way, only the first pull rod 515 needs to be pushed upward to lock the position of the top rod 507 under the action of the spring. It should be further noted that any other components used to achieve the above effect should fall within the inventive concept of this utility model and should be within the protection scope of this utility model.

[0040] Working principle: Locate the mounting position of the heat sink on the PCB board. Based on the position of the opening on the PCB board, adjust the relative position of the pin plug 4 on the heat sink 2 so that the pin 402 is aligned with the opening on the PCB board. Then fix the pin plug 4 by riveting or other methods, and then install the heat sink. There is no need to consider the compatibility between the heat sink and the PCB hole position, making positioning more convenient. It can maximize the compatibility of the heat sink, reduce the difficulty of operation, and improve the efficiency of operation.

[0041] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
