Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to a highly insulating conductive foam. Background Technology

[0002] Conductive foam refers to conductive fabric wrapped around flame-retardant sponge. After a series of treatments, it achieves good surface conductivity and can be easily fixed to the device requiring shielding with adhesive tape. Shielding materials with different cross-sectional shapes, installation methods, UL ratings, and shielding effectiveness are available. Existing conductive foams, when in use, have their entire bottom covered with double-sided adhesive. This results in significant adhesive residue on the shielding device during subsequent replacements, making cleaning difficult. It also consumes a large amount of material, and the solid inner surface of the conductive foam leads to high overall material density and waste. Furthermore, conductive foam itself has low resilience, resulting in poor cushioning and insulation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a highly insulating conductive foam, solving the technical problem of excessive material usage in conductive foam.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a highly insulating conductive foam, comprising multiple continuously arranged bodies, which are inserted and fixed together. Each body is composed of a foam core and a conductive cloth, and the conductive cloth is bonded and attached to the foam core.

[0005] The middle part of the main body is an "O" shape with an opening, forming a hollow structure. The two ends of the main body extend outward and form an outer bend and an inner bend. An outer fold edge is provided on the outer bend and an inner fold edge is provided on the inner bend. The outer fold edge and inner fold edge of adjacent main bodies are adapted to each other and inserted and fixed.

[0006] Preferably, an adhesive layer is provided at the bottom of the body near the outward bend, and a protective patch is attached to the bottom of the adhesive layer.

[0007] Preferably, the adhesive layer is double-sided tape.

[0008] Preferably, the inner side of the body is fixed with a cladding layer, and a flame-retardant layer is disposed inside the cladding layer.

[0009] Preferably, the flame-retardant layer is specifically aluminum hydroxide flame retardant.

[0010] Preferably, the inner side of the outer bend is provided with a slanted side that blocks one end of the inner bend.

[0011] By employing the above technical solution, this utility model provides a highly insulating conductive foam, which has at least the following beneficial effects:

[0012] 1. This highly insulating conductive foam, by setting out outer and inner bends, only applies double-sided adhesive to the bottom of the outer bend, which reduces the amount of double-sided adhesive used, saves materials, and facilitates later cleaning. At the same time, since the outer and inner bends of adjacent bodies are adapted and interlocked, the inner bend without double-sided adhesive can be interlocked with the outer bend of the adjacent body to form a fixed structure, ensuring overall sturdiness while reducing material usage.

[0013] 2. This highly insulating conductive foam, by making the middle position of the body into an "O" shape with an opening and forming a hollow structure, can further reduce the amount of material used and increase the overall height of the conductive foam, thereby improving its resilience and insulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Conductive foam is extremely lightweight and possesses electromagnetic shielding properties, ensuring permanent electrostatic protection for products. Its light weight also reduces surface impedance and makes it unaffected by environmental humidity. Conductive 102 foam also exhibits excellent corrosion and oxidation resistance, fully meeting the needs of high-tech enterprises in optoelectronics, microelectronics, aerospace, communications, military, and chemical industries for novel antistatic materials.

[0023] Due to the technical drawback of existing technologies, which require a large amount of materials, please refer to... Figures 1-4 This utility model provides a highly insulating conductive foam, which only has double-sided adhesive on the bottom of the outer bend 103, reducing the amount of double-sided adhesive used, saving materials and facilitating later cleaning. It includes multiple continuously arranged bodies 1, which are inserted and fixed together. Each body 1 consists of a foam core 101 and a conductive cloth 102, which is bonded and covered to the foam core 101. In use, the protective patch 106 at the bottom of the body 1 is peeled off to expose the double-sided adhesive, and then the body 1 is bonded to the shielding device with the double-sided adhesive. When connecting subsequent bodies 1, the inner bend 104 on the adjacent body 1 is first inserted into the outer bend 103 on the previous body 1, and then the subsequent body 1 is bonded.

[0024] Because the inner side of existing conductive foam is solid, firstly, the overall material density is high, leading to material waste; secondly, the conductive foam itself has low resilience, resulting in poor cushioning and insulation. To address this issue, please refer to... Figure 2 The middle position of the main body 1 is an "O" shape with an opening, forming a hollow structure. The two ends of the main body 1 extend outward to form an outer bend 103 and an inner bend 104. The outer bend 103 is provided with an outer folded edge, and the inner bend 104 is provided with an inner folded edge. The outer folded edge and inner folded edge between adjacent main bodies 1 are adapted to each other and inserted and fixed. By making the middle position of the main body 1 an "O" shape with an opening and forming a hollow structure, on the one hand, the amount of material used can be further reduced, and on the other hand, the overall height of the conductive foam can be increased, thereby improving its resilience and insulation. In addition, the inner bend 104 without double-sided adhesive can be inserted into the outer bend 103 of the adjacent main body 1 to form a fixed structure, thereby reducing the amount of material used while ensuring overall firmness.

[0025] When in use, the main body 1 needs to be attached to the shielding device. Therefore, an adhesive layer 105 is provided at the bottom of the main body 1 near the outer bend 103. A protective patch 106 is attached to the bottom of the adhesive layer 105. The protective patch 106 protects the adhesive layer 105. When in use, the protective patch 106 can be peeled off to expose the adhesive layer 105.

[0026] Furthermore, the adhesive layer 105 is specifically double-sided adhesive; both sides of the double-sided adhesive are sticky, so that the body 1 can be attached to the shielding device.

[0027] When the shielding device catches fire, a cladding layer 107 is fixed inside the body 1, and a flame-retardant layer 108 is provided inside the cladding layer 107; the flame-retardant layer 108 is used to retard the fire part of the shielding device, thereby reducing damage to other devices.

[0028] Furthermore, the flame retardant layer 108 is specifically an aluminum hydroxide flame retardant.

[0029] Since the inner bend 104 of the adjacent body 1 is inserted into the outer bend 103, by providing a beveled edge on the inner side of the outer bend 103 to block one end of the inner bend 104, the movement of the inner bend 104 is restricted by using the beveled edge to block one end of the inner bend 104, thereby avoiding the problem of the inner bend 104 detaching when squeezing the body 1.
