Description
Technical Field
[0001] This utility model relates to the technical field of gasket products, and in particular to a multifunctional gasket assembly for computer motherboard power interfaces. Background Technology
[0002] The motherboard power connector is a crucial component of computer hardware, responsible for providing a stable power supply to the motherboard and ensuring the normal operation of the entire computer system. During computer operation, the power connector is subjected to mechanical stress, especially when plugging and unplugging the power cable, which may generate impact forces. Furthermore, the computer may be subjected to vibration during handling or use, all of which can damage the power connector and the motherboard. Additionally, to ensure a good electrical connection between the power connector and the motherboard, a material with stable conductivity is needed. Moreover, in certain special conditions, such as environments with strong electromagnetic interference, materials with electromagnetic shielding capabilities are also required for the motherboard power connector. Therefore, a motherboard power connector gasket with cushioning, shock absorption, and conductivity is essential. It not only protects the connector from mechanical damage but also provides a stable electrical connection and electromagnetic shielding, making it one of the key components ensuring the stable operation of computers and other electronic devices.
[0003] Existing pads for electronic devices cannot simultaneously provide optimal cushioning and shock absorption as well as conductivity, and cannot adequately meet the requirements of computer motherboard power interfaces for electrical connection stability and mechanical structure reliability. Utility Model Content
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-functional gasket assembly for computer motherboard power interfaces. This multi-functional gasket assembly can provide superior buffering and shock absorption, conductivity and electromagnetic shielding functions, and can well meet the requirements of computer motherboard power interfaces for electrical connection stability and mechanical structure reliability.
[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0006] A multifunctional gasket assembly for a computer motherboard power connector includes a gasket body, which comprises a base film and a conductive foam assembly. The base film has an adhesive surface. The conductive foam assembly includes a conductive foam block and a conductive cloth disposed on one side of the conductive foam block. The conductive cloth is disposed on the adhesive surface of the base film. The side of the conductive foam block facing away from the conductive cloth is the adhesive surface, used to mate with the power connector. A release film is also provided on the base film at the conductive foam assembly. A portion of the conductive cloth contacts the release film, and the release surface of the release film contacts the conductive cloth.
[0007] Furthermore, the gasket body is disposed on one side of the material strip, and a roll of material pad film is arranged on the other side of the material strip. A padding strip is provided on the side of the roll of material pad film that is close to the material strip.
[0008] Furthermore, the width of the roll pad film is greater than the width of the strip, and both sides of the roll pad film are provided with padding strips extending along the length of the roll pad film.
[0009] Furthermore, the shim strip is a textured silicone shim strip, which is bonded to the roll pad film via an adhesive layer.
[0010] Furthermore, the gasket body is fixed to the material strip by an adhesive film strip.
[0011] Furthermore, the conductive foam assembly includes multiple conductive foam blocks, the arrangement of which on the base film is adapted to the power interface of the power motherboard.
[0012] Furthermore, the conductive cloth is a single-sided adhesive conductive cloth, which is bonded to the conductive foam block through the adhesive side.
[0013] Furthermore, a conductive copper foil assembly is provided on the bottom film near the conductive foam assembly. The conductive copper foil assembly includes a conductive double-sided adhesive layer and a copper foil component. The conductive double-sided adhesive layer is used to cooperate with the power interface of the computer motherboard.
[0014] Furthermore, the conductive copper foil assembly also includes a silicone protective film, the silicone protective film having an adhesive surface that mates with the copper foil, and the side of the silicone protective film facing away from the adhesive surface mates with the adhesive surface of the base film.
[0015] Furthermore, the bottom membrane is also provided with positioning holes.
[0016] The beneficial effects of this utility model are:
[0017] The multifunctional gasket assembly of this utility model includes a base film and a conductive foam assembly. The conductive foam assembly includes a conductive cloth and a conductive foam block. The conductive cloth and the conductive foam block work together to provide better and more stable conductivity, providing a stable conductive path between the power interface and the motherboard, reducing contact resistance and impedance, and ensuring a good electrical connection between the power interface and the motherboard. The conductive cloth and the conductive foam block also provide electromagnetic shielding. The conductive foam block provides better cushioning and shock absorption, protecting the power interface from mechanical damage.
[0018] In this invention, a release film is also provided on the bottom film at the conductive foam component. A portion of the release film is in contact with the conductive foam component, and the release surface of the release film is in contact with the conductive foam component. Since the conductive foam block is made by foaming and has many pores, if the bottom film is directly bonded to the conductive foam component, the conductive foam block and conductive cloth are easily delaminated when the bottom film is removed after the gasket is applied to the power interface, thus affecting the impedance and conductivity stability. By designing the release film to partially contact the conductive foam component, the adhesion between the conductive foam component and the bottom film can be ensured, while the difficulty of removing the bottom film can be reduced, and the delamination of the conductive cloth and conductive foam block can be avoided.
[0019] To further provide better conductivity, this invention also includes a conductive copper foil assembly. A silicone protective film is provided between the conductive copper foil assembly and the base film. The conductive copper foil assembly adheres better to the base film through the silicone protective film. The adhesive side of the base film is attached to the conductive foam assembly, and the adhesive side of the silicone protective film is attached to the conductive copper foil assembly. The two films with different adhesive properties are specifically attached to the surfaces of different materials, which can achieve a better adhesion effect.
[0020] This utility model's multifunctional gasket assembly can simultaneously provide superior cushioning and shock absorption, conductivity, and electromagnetic shielding, thus effectively meeting the stability requirements of electrical connections and the reliability requirements of mechanical structures in computer motherboard power interfaces. Furthermore, this multifunctional gasket assembly is convenient, time-saving, labor-saving, and cost-effective in use. Attached Figure Description

Detailed Implementation
[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0028] like Figures 1 to 5 As shown, this utility model provides a multifunctional gasket assembly for a computer motherboard power interface, which includes a gasket body 1.
[0029] This multi-functional gasket assembly can be used for roll products. Specifically, such as... Figure 1 As shown, several gasket body components 1 are bonded to one side of a material strip 3 by adhesive film strips 2. A roll of material padding film 4 is arranged on the other side of the material strip 3. The width of the roll of material padding film 4 is greater than the width of the material strip 3, and both sides of the roll of material padding film 4 have shims 5 extending along its length on the side closest to the material strip. The material strip 3 is made of antistatic release film material, and its release surface contacts the gasket body components 1. The shims 5 are textured silicone shims, which are attached to the roll of material padding film 4 by an adhesive layer on one side. Through the design of the roll of material padding film 4 and the shims 5, a certain degree of isolation can be achieved between the roll layers during winding, and the shims 5 prevent the gasket body components 1 from being subjected to external pressure, thus avoiding deformation and thinning of the gasket body components.
[0030] The gasket body 1 includes a base film 11 and a conductive foam assembly 12. The base film 1 has an adhesive side and an opening 112 adapted to a power interface. The conductive foam assembly 12 includes a conductive foam block 121 and a conductive cloth 122 disposed on one side of the conductive foam block 121. The conductive foam block 121 is adhesive on one side, meaning the side facing away from the conductive cloth 122 is the adhesive side, used to mate with the power interface. The conductive cloth 122 is adhesive on one side, meaning the side closest to the conductive foam block 121 is the adhesive side, used to bond and adhere to the conductive foam block 121. The side of the conductive cloth 122 without an adhesive side is attached to the adhesive side of the base film 11. The adhesive side of the conductive foam block 121 is in contact with the material strip 3.
[0031] The conductive cloth 122 and the conductive foam block 121 work together to provide better and more stable conductivity, providing a stable conductive path between the power interface and the motherboard, reducing contact resistance and impedance, and ensuring a good electrical connection between the power interface and the motherboard. The conductive cloth 122 and the conductive foam block 121 also provide electromagnetic shielding. The conductive foam block 121 provides better cushioning and shock absorption, protecting the power interface from mechanical damage.
[0032] The number of conductive foam blocks 121 can be set to multiple, and the layout of these multiple conductive foam blocks 121 on the bottom film 11 is adapted to the power interface of the power motherboard.
[0033] On the adhesive side of the base film 11, a release film 13 is also provided at the conductive foam assembly. Only a portion of the conductive cloth 122 is in contact with the release film 13, and the release surface of the release film 13 is in contact with the conductive cloth 122. The partial contact between the release film 13 and the conductive foam assembly 12 ensures the adhesion between the conductive foam assembly 12 and the base film 11, while also reducing the difficulty of removing the base film 11 during use. This prevents delamination between the conductive cloth 122 and the conductive foam block 121, ensuring that the impedance is not affected and improving the conductivity stability and electrical connection stability.
[0034] To further improve conductivity, a conductive copper foil assembly 14 is provided on the adhesive side of the base film 11 near the conductive foam assembly. The conductive copper foil assembly 14 includes a conductive double-sided adhesive layer 141, a copper foil component 142, and a silicone protective film 143 arranged sequentially from top to bottom. The conductive double-sided adhesive layer 141 is used to cooperate with the power interface of the computer motherboard. The silicone protective film 143 has an adhesive surface that cooperates with the copper foil component 142, and the side of the silicone protective film 143 facing away from this adhesive surface is attached to the adhesive surface of the base film 11. The silicone protective film 143 allows the copper foil component 142 to adhere better to the base film 11.
[0035] In order to better position the pad body 1 in conjunction with the power interface during use, the bottom film 1 is also provided with a positioning hole 111. The design position of the positioning hole 111 can be designed according to the power interface structure.

In this embodiment, the conductive foam block 121 is model BZF7006, with an adhesive strength ≥1.2 kg / sq inch, surface resistance ≤0.13 Ω / sq inch, and a thickness of 0.6 mm. In this embodiment, three conductive foam blocks 121 are used. The conductive cloth 122 is adhesive on one side, meaning the side closest to the conductive foam block is the adhesive side, used to bond and attach to the conductive foam block 121. In this embodiment, the conductive cloth 122 is model LH-952, with an adhesive strength ≥0.7 kg / inch, surface resistance ≤0.05 Ω / sq inch, vertical resistance ≤0.03 Ω / sq inch, and a thickness of 0.03 mm. The side of the conductive cloth 122 without adhesive is attached to the adhesive side of the base film 11; the adhesive side of the conductive foam block 121 is in contact with the material strip 3.
[0041] On the adhesive side of the bottom film 11, a release film 13 is also provided at the conductive foam assembly. Only a small portion of the conductive cloth 122 in the conductive foam assembly 12 contacts the release film 13, and the release surface of the release film 13 contacts the conductive cloth 122. In this embodiment, the release film 13 is model 28PP003W, with a release force of 3±2g / 25mm and a thickness of 0.031mm.
[0042] To further improve conductivity, a conductive copper foil assembly 14 is provided on the adhesive side of the base film 11 near the conductive foam assembly. The conductive copper foil assembly 14 includes a conductive double-sided adhesive layer 141, a copper foil component 142, and a silicone protective film 143 arranged sequentially from top to bottom.
