[0029] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, a fixing device for a radiator MOS tube is used to fix the MOS tube on a radiator 500. Referring to Figure 6 As shown, screw holes for fixing the MOS tube are provided on one surface of the radiator 500 in contact with the MOS tube, and it includes: a base 100 and a cover plate 200. Specifically, a groove 110 matching the shape of the radiator 500 is formed on the front surface of the base 100. The cover plate 200 is detachably connected to the front surface of the base 100, and a plurality of card slots 210 corresponding to the screw holes one by one are formed on the cover plate 200. The shape of the card slots 210 matches that of the MOS tube.

[0030] In the embodiments of the present application, a groove 110 matching the radiator 500 is provided on the base 100. The radiator 500 can be placed in the groove 110, thereby realizing the limitation of the horizontal displacement of the radiator 500. After the radiator 500 is placed in the groove 110, the cover plate 200 is installed on the base 100. The card slots 210 on the cover plate 200 correspond to the screw holes on the radiator 500. Therefore, after the MOS transistor is placed in the card slots 210, the MOS transistor can be directly fixed on the radiator 500 through bolts. The present application does not require manual visual alignment, and the MOS transistor can be conveniently fixed on the radiator 500. The operation is simple, the working efficiency is high, and the labor cost is low.

[0031] In the above embodiments, a groove 110 matching the shape of the radiator 500 is provided on the front surface of the base 100, which means that a groove 110 capable of exactly accommodating the radiator 500 is provided on the upper surface of the base 100. After the radiator 500 is placed in the groove 110, a horizontal plane limitation can be formed on the radiator 500 to prevent the radiator 500 from moving back and forth or left and right. At the same time, card slots 210 are provided on the cover plate 200, and the card slots 210 correspond one by one to the screw holes, which means that when the MOS transistor is placed in the card slots 210, the screw hole installation positions of the MOS transistor exactly align with the screw holes of the radiator 500. Therefore, the MOS transistor and the radiator 500 can be directly fixed together through bolts to achieve close contact without manual visual alignment, which is worry-free and labor-saving, improves the processing efficiency, and saves labor costs.

[0032] It should be noted that the cover plate 200 is detachably connected to the front surface of the base 100, which means that the cover plate 200 can be covered and fixed on the base 100 during installation, wrapping the radiator 500 in the groove 110 to form a fixation in the vertical direction of the radiator 500. The cover plate 200 can be fixed to the base 100 by means of snap connection, or can be fixed and detached from the base by means of a third-party fixture, the cooperation of bolts and screw holes, or other detachable connection methods.

[0033] In some embodiments of the present application, positioning posts 120 are provided on the front surface of the base 100, and card holes matching the positioning posts 120 are provided on the cover plate 200.

[0034] In this embodiment, by providing the positioning posts 120 on the base 100 and the card holes on the cover plate 200, when installing, directly align the card holes with the positioning posts 120 and press down to complete the installation of the cover plate 200 and the base 100, which is simple and convenient.

[0035] In some embodiments of the present application, there are two positioning posts 120, and the two positioning posts 120 are respectively provided on the base 100 on both sides of the groove 110.

[0036] In this embodiment, the two positioning posts 120 are respectively arranged on both sides of the groove 110, so that the left and right sides of the cover plate 200 can be clamped through the positioning posts 120, improving the stability of the overall structure.

[0037] It should be noted that in this application, the two positioning posts 120 are relatively arranged on both sides of the groove 110 in a diagonal manner, which can further improve the stability of the structure. Of course, in addition to arranging the two positioning posts 120 in a diagonal manner, a symmetric arrangement on the same horizontal line or other arrangement methods can also be adopted.

[0038] In some embodiments of this application, an insulating sheet 300 is further included. The insulating sheet 300 is used to isolate the MOS transistor from the radiator 500, and an opening matching the screw hole is provided on the insulating sheet 300.

[0039] In this embodiment, adding an insulating sheet 300 between the MOS transistor and the radiator 500 can achieve insulation between the MOS transistor and the radiator 500.

[0040] Reference Figure 4 As shown, since insulation needs to be achieved between the MOS transistor and the radiator 500, the radiator 500 can be made of an insulating material. If the radiator 500 is made of a non-insulating material, an insulating sheet 300 needs to be provided between the MOS transistor and the radiator 500. The insulating sheet 300 is provided with openings corresponding one by one to the screw holes on the radiator 500, which means that when the MOS transistor and the radiator 500 are fixed by bolts, the bolts can extend into the screw holes on the radiator 500 through the openings on the insulating sheet 300, avoiding obstruction of the bolts by the insulating sheet.

[0041] In some embodiments of this application, an insulating sheet fixing plate 400 is arranged between the cover plate 200 and the insulating sheet 300, and an opening 410 adapted to the card slot 210 is arranged in the middle area of the insulating sheet fixing plate 400.

[0042] In this embodiment, an insulating sheet fixing plate 400 is arranged between the cover plate 200 and the insulating sheet 300, and the insulating sheet 300 is fixed through the insulating sheet fixing plate 400, which can prevent the insulating sheet 300 from moving and improve the stability of the overall structure.

[0043] Reference Figure 5As shown, the shape of the edge of the insulating sheet fixing plate 400 is similar to that of the cover plate 200. The insulating sheet fixing plate 400 is also provided with a clamping hole that cooperates with the positioning post 120 for clamping. An opening 410 is provided in the middle area of the insulating sheet fixing plate 400. The shape of the opening 410 is adapted to the card slot 210, which means that the area of the opening 410 on the insulating sheet fixing plate 400 is greater than or equal to the area of the card slot 210 on the cover plate 200. In this way, when the insulating sheet fixing plate 400 is installed between the cover plate 200 and the insulating sheet 300, the insulating sheet fixing plate 400 will not block the MOS transistor.

[0044] Reference Figure 1 As shown below, the overall installation process of the present application will be described:

[0045] Before installation, the base 100, the cover plate 200, the insulating sheet 300, the insulating sheet fixing plate 400, and the radiator 500 are in a split structure;

[0046] First, place the radiator 500 in the groove 110 of the base 100, then place the insulating sheet 300 on the radiator 500, align the opening on the insulating sheet 300 with the screw hole on the radiator 500, and then align the clamping hole of the insulating sheet fixing plate 400 with the positioning post 120 on the base 100 for clamping to fix the insulating sheet 300. Then, align the clamping hole of the cover plate 200 with the positioning post 120 for clamping to form an integral body of the base 100, the cover plate 200, the insulating sheet 300, the insulating sheet fixing plate 400, and the radiator 500. Finally, place the MOS transistor into the card slot 210 and fix the MOS transistor to the radiator 500 with bolts to complete the installation.

[0047] It should be noted that the above is only one installation method of the present application. When only the base 100 and the cover plate 200 are present, the installation steps of the corresponding insulating sheet 300 and the insulating sheet fixing plate 400 can be removed.

[0048] The present application also relates to an electronic device, and the above-mentioned radiator MOS transistor fixing device is provided inside the electronic device.

[0049] The electronic device of the present application can be any power device with an internal MOS transistor, such as a high-power switching power supply, a source-load integrated machine, a source meter, etc.

[0050] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
