Description

Technical Field

[0001] The utility model relates to the technical field of silicone gaskets, in particular to a heat-conducting silicone gasket which is convenient to position. Background Art

[0002] The function of thermally conductive silicone sheets is to dissipate heat, improve the heat dissipation effect, and protect electronic components from overheating damage. Thermally conductive silicone sheets can reduce the thermal resistance of electronic components, quickly conduct the heat generated by the components to the radiator or heat sink, increase the heat dissipation rate, and maintain the normal operating temperature of the components. At the same time, thermally conductive silicone sheets can also fill uneven surfaces, improve the quality of heat dissipation contact, reduce contact resistance, and improve thermal conductivity. However, when existing thermally conductive silicone sheets are bonded to the surface of electronic components, they are usually aligned with the surface of the electronic components little by little after tearing off the protective film on the surface of the substrate. The process is time-consuming and requires repeatedly tearing off the thermally conductive silicone sheets adhered to the surface of the electronic components to correct the position, which affects the adhesion and increases the overall time consumption. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a thermally conductive silicone gasket that is easy to position, so as to solve the problem that some thermally conductive silicone gaskets proposed in the above background technology need to repeatedly correct the bonding position when bonding with the surface of components, which increases the overall time consumption and affects the adhesion.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat-conducting silicone gasket that is easy to position, comprising a heat-conducting silicone body, a U-shaped bar is fixedly connected between the back and both sides of the heat-conducting silicone body, three evenly arranged positioning components are installed on the U-shaped bar, and one side of the three positioning components is respectively in contact with the back and both side surfaces of the heat-conducting silicone body;

[0005] The positioning assembly includes a sleeve frame structure fixedly inserted on the U-shaped bar, and the inner walls on both sides of the sleeve frame structure are provided with sliding grooves. The side of the sleeve frame structure close to the thermal conductive silicone body is provided with an open groove. An extension block is slidably installed inside the sleeve frame structure, and one side of the extension block is in contact with the outer surface of the thermal conductive silicone body, and protruding blocks extending into the interior of the sliding groove are fixedly installed on both sides of the extension block.

[0006] Preferably, the thermally conductive silicone body comprises a thermally conductive silicone base material and two protective films arranged up and down, and the two protective films are respectively glued to the top surface and the bottom surface of the thermally conductive silicone base material.

[0007] Preferably, the combined height of the frame structure and the extension block is greater than the thickness of the thermally conductive silicone body, and the outer surface of the upper protective film is fixedly connected to the inner wall of the recessed portion of the U-shaped strip.

[0008] Preferably, a plurality of evenly arranged through grooves are formed on the top of the U-shaped strip, and one side of the through grooves is connected to the outer surface of the protective film.

[0009] Preferably, a convex tear piece is fixedly connected to the middle of the front sides of the two protective films, and the convex tear piece is arranged in a rectangular shape.

[0010] Preferably, an adhesive layer is provided on opposite sides of the two outwardly convex tearing pieces, and a ball-moving structure is fixedly connected to one side of one of the outwardly convex tearing pieces.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, when the thermal conductive silicone gasket is driven to fit onto the covered object, due to the gravity of the extension block in the positioning component, it slides downward along the inside of the sleeve frame structure, increasing the overall height of the positioning component, so that when the thermal conductive silicone sheet is fitted onto the surface of the covered object, one side of the three positioning components is preferentially fitted onto the back and both sides of the covered object, thereby ensuring that when the subsequent thermal conductive silicone gasket is fitted, its rear edge and both side edges can be aligned with the edge of the covered object, thereby playing an effective positioning role and improving the pasting efficiency and effect.

[0013] 2. In the present invention, the two protruding tearing pieces for facilitating tearing off the protective film are attached to the front middle part of the thermally conductive silicone body in the initial state, so as to prevent the protective film from being separated from the thermally conductive silicone body due to accidental contact of the protruding tearing pieces.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] To solve the problem that some existing thermal conductive silicone gaskets need to be repeatedly corrected when they are attached to the surface of components, which increases the overall time consumption and affects the adhesion, please refer to Figure 1-Figure 4 , an embodiment provided by the utility model:

[0021] A heat-conducting silicone gasket that is easy to position comprises a heat-conducting silicone body 1, a U-shaped bar 2 is fixedly connected to the back and both sides of the heat-conducting silicone body 1, three evenly arranged positioning components 3 are installed on the U-shaped bar 2, and one side of the three positioning components 3 is respectively in contact with the back and both side surfaces of the heat-conducting silicone body 1;

[0022] Specifically, the positioning component 3 includes a sleeve frame structure 301 fixedly plugged into the U-shaped bar 2, and the inner walls of both sides of the sleeve frame structure 301 are provided with sliding grooves 302. The opening groove is provided on one side of the sleeve frame structure 301 close to the thermal conductive silicone body 1, so that the extension block 303 installed inside the sleeve frame structure 301 can be fitted with the outer surface of the thermal conductive silicone body 1 like one side of the surface of the sleeve frame structure 301. Both sides of the extension block 303 are fixedly provided with protruding blocks 304 extending into the interior of the sliding groove 302, and the extension block 303 can be fixedly installed with the protruding blocks 304 extending into the interior of the sliding groove 302. The protruding block 304 and the sliding groove 302 are matched to prevent the extension block 303 from sliding up and down inside the sleeve frame structure 301 under the action of external force, and prevent the two from being out of contact. The thermal conductive silicone body 1 includes a thermal conductive silicone substrate 101 and a protective film 102 glued to the top and bottom surfaces of the thermal conductive silicone substrate 101. The combined height of the sleeve frame structure 301 and the extension block 303 is greater than the thickness of the thermal conductive silicone body 1. The outer surface of the upper protective film 102 is fixedly connected to the inner wall of the concave part of the U-shaped strip 2.

[0023] Furthermore, by tearing off the protective film 102 at the lower middle part of the thermally conductive silicone gasket, and then moving the thermally conductive silicone gasket to the top of the object to be covered, and then driving it to move downward, during this process, due to the gravity of the extension block 303 itself, the three positioning components 3 slide downward along the inside of the frame structure 301, thereby increasing the overall height of the positioning component 3, so that one side of it is preferentially attached to the back and both sides of the covered object, so as to ensure that when the thermally conductive silicone gasket is attached downward, its rear edge and both side edges are aligned with the edge of the uncovered object, and then play a positioning role when the thermally conductive silicone gasket is used, so that it is convenient to paste it on the surface of the covered object, and it is successful at one time, ensuring the effect of subsequent pasting; in addition, in the positioning component 3, the height of the frame structure 301 is consistent with the thickness of the thermally conductive silicone body 1, and when the bottom of the extension block 303 is pushed upward, it can shrink into the space inside the frame structure 301, thereby changing the overall height between the two, and then ensuring the flatness of multiple thermally conductive silicone gaskets when stacked.

[0024] Reference Figure 1 As shown, a plurality of evenly arranged through grooves 201 are provided on the top of the U-shaped strip 2, and one side of the through groove 201 is interconnected with the outer surface of the protective film 102. The setting of the through groove 201 can reduce the contact area between the U-shaped strip 2 and the surface of the protective film 102, making it convenient to tear off the U-shaped strip 2 and separate it from the upper protective film 102 after the thermal conductive silicone body 1 is bonded to the surface of the covered object.

[0025] Reference Figure 1 , Figure 2 and Figure 4 As shown, the middle of the front of the two protective films 102 are fixedly connected with a convex tear sheet 4, and the convex tear sheet 4 is arranged in a rectangular shape, and the two convex tear sheets 4 are provided with an adhesive layer 401 on the opposite side, and one side of the convex tear sheet 4 is fixedly connected with a ball-moving structure 402;

[0026] Specifically, in the initial state of the thermally conductive silicone gasket, an outwardly protruding tear piece 4 with a ball-pull structure 402 is adhered to the front side of the thermally conductive silicone body 1 through an adhesive layer 401, while another outwardly protruding tear piece 4 is adhered to the outer surface of the previous outwardly protruding tear piece 4 through the adhesive layer 401, so as to tightly fit the outwardly protruding tear piece 4 to the thermally conductive silicone body 1, thereby effectively preventing the outwardly protruding tear piece 4 from causing the protective film 102 to separate from the thermally conductive silicone body 1 due to accidental contact. When the protective film 102 needs to be torn off later, a pulling force toward the front side is applied to the ball-pull structure 402 in advance, so as to break the two outwardly protruding tear pieces 4 off the thermally conductive silicone body 1.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
