[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor under the premise that the scope of protection of the present application is involved.

[0021] The size of the existing insulating high-thermal-conductivity silicone gasket is usually preset and cannot be changed once determined. The fixed size makes them unable to effectively cover the entire contact surface when facing larger-sized electronic components, resulting in insufficient heat transfer. Due to the limited heat conduction effect, the silicone gasket cannot effectively dissipate heat in this case, thereby affecting its application on larger power or larger volume electronic components. This characteristic significantly limits the use range of the silicone gasket, especially in scenarios requiring higher heat management capability, which cannot meet the demand. Please refer to Figures 1-4The embodiment provides an insulating high-thermal-conductivity silica gel gasket, which comprises a silica gel gasket body 1, a frame 2 arranged outside the silica gel gasket body 1, and a splicing assembly 3 arranged on both sides of the frame 2. The splicing assembly 3 comprises an elastic sheet 31 arranged on one side of the frame 2. The elastic sheet 31 is shaped like >. The outer wall of the elastic sheet 31 is coated with at least three smooth layers of paint. The material of the smooth layers of paint comprises, but is not limited to, epoxy resin, polyurethane and acrylic resin material. In the application process, the elastic sheet 31 is placed in a rectangular groove 34. Due to the special > shape, when the elastic sheet 31 is placed in the rectangular groove 34, the shape of the elastic sheet 31 will change. Specifically, when the elastic sheet 31 enters the rectangular groove 34, due to the design of the shape, the elastic sheet 31 will be compressed or bent at the opening of the compression groove 351. Due to the smooth layer of paint, the friction between the surface and the contact surface is significantly reduced, the occurrence of wear is reduced, the smooth coating ensures the smoothness of the surface, further improves the wear resistance and service life, prolongs the service life, and improves the overall performance and stability. The inner wall of the elastic sheet 31 is fixed with a connecting rod 32. The end of the connecting rod 32 away from the elastic sheet 31 is fixed with a rectangular block 33. The inner wall of the other side of the frame 2 is provided with a rectangular groove 34. The inner wall of the rectangular groove 34 is provided with a regulating groove 35. The regulating groove 35 is communicated with the compression groove 351 and the outlet groove 352 and is composed of the compression groove 351 and the outlet groove 352. The height ratio of the compression groove 351 to the outlet groove 352 is 1:2. In order to expand the use range, a plurality of silica gel gasket bodies 1 can be spliced. Specifically, the elastic sheet 31 on one side of one frame 2 is aligned with the compression groove 351 on the other side of another frame 2 and is placed into the rectangular groove 34, so that the elastic sheet 31 changes in shape during the placement process. When the elastic sheet 31 is completely placed into the rectangular groove 34, the elastic sheet 31 returns to the original state by its own elastic property. At this time, the elastic sheet 31 cannot be taken out in reverse, and the rectangular block 33 is matched with the compression groove 351, so that the splicing of the plurality of silica gel gasket bodies 1 is completed. When it is necessary to split, the frame 2 is slid, the elastic sheet 31 slides in the rectangular groove 34, the elastic sheet 31 moves away from the compression groove 351 and is connected with the outlet groove 352, the height ratio of the compression groove 351 to the outlet groove 352 is 1:2, the elastic sheet 31 smoothly leaves the rectangular groove 34, and thus the two silica gel gasket bodies 1 are split. By splicing a plurality of silica gel gasket bodies 1, the use range of the silica gel gasket body 1 can be flexibly expanded to meet different size requirements. The cooperation of the elastic sheet 31, the compression groove 351 and the rectangular groove 34 ensures that the spliced silica gel gasket body 1 is firm and not easy to be disassembled. By adjusting the height ratio of the compression groove 351 to the outlet groove 352, the elastic sheet 31 can be easily slid and separated from the rectangular groove 34, which is convenient for splitting. The splicing structure is suitable for silica gel gasket bodies 1 that need to be flexibly combined and split, especially when a large area is needed, the size can be quickly spliced and adjusted.

[0022] As Figure 2As shown, the inside of the silicone gasket body 1 is provided with a filler with high thermal conductivity while maintaining the insulating property of the silicone gasket body 1, and the material of the filler includes but is not limited to aluminum nitride, silicon nitride, aluminum oxide, and graphite powder material. The thermal conductivity of silicone itself is low, so a filler with high thermal conductivity is selected to enhance its thermal conductivity while maintaining the insulating property of silicone. The filler can improve the thermal conductivity of the material without significantly affecting its electrical insulation properties. The top and bottom of the silicone gasket body 1 are provided with a thermal conductive layer 4, and the thermal conductive layer 4 is flush with the frame 2. The material of the frame 2 and the thermal conductive layer 4 includes but is not limited to beryllium copper alloy material. The thermal conductive layer 4 is provided on the top and bottom of the silicone gasket body 1, which can improve the heat conduction effect and help dissipate heat. The material of the thermal conductive layer 4, such as beryllium copper alloy, has excellent thermal conductivity and can quickly conduct the heat generated by the heating device to the heat sink. The frame 2 is made of beryllium copper alloy, which has high strength, high hardness, small elastic hysteresis, corrosion resistance and other excellent properties. These characteristics of beryllium copper alloy ensure that the frame 2 will not deform when subjected to external pressure (such as the weight of the heat sink), thereby providing additional structural support. Place the heating device at the bottom of the frame 2 flush with the frame 2 and the thermal conductive layer 4, and place the heat sink on the top of the frame 2 flush with the frame 2 and the thermal conductive layer 4. The silicone gasket body 1 acts as a thermal interface material responsible for transferring heat between the heat sink, the heating device and the frame. The heat sink is located on the top of the frame 2 and is flush with the frame 2 and the thermal conductive layer 4, ensuring efficient heat transfer. Due to the high thermal conductivity of beryllium copper alloy, the heat sink can quickly dissipate heat and prevent excessive temperature from affecting stability.

[0023] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
