Description

Technical Field

[0001] The utility model relates to the technical field of conductive foam, in particular to a high-temperature resistant conductive foam. Background Technique

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. There are different cross-sectional shapes, installation methods, UL grades and shielding effectiveness shielding materials to choose from.

[0003] In view of the above-related technologies, the flame-retardant sponge is wrapped with conductive cloth inside, but the internal heat conduction performance is not good. During the long-term conduction process, the heat release inside is very slow, and the temperature inside the flame-retardant sponge rises rapidly, which will affect the current conduction and reduce the transmission effect.

[0004] Therefore, the utility model provides a high-temperature resistant conductive foam to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a high-temperature resistant conductive foam, which solves the above problems.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: a high-temperature resistant conductive foam, including a foam body, an insulating sleeve is installed on the outer wall of the foam body, a flame-retardant sleeve is installed on the outer wall of the insulating sleeve, a conductive cloth is installed on the outer wall of the flame-retardant sleeve, a shielding layer is installed on the outer wall of the conductive cloth, a number of heat dissipation rods are evenly installed inside the foam body, and heat dissipation openings are provided at the positions corresponding to the foam body, the insulating sleeve, the conductive cloth, the shielding layer and the flame-retardant sleeve on the heat dissipation rods.

[0007] Through the above technical solutions, the foam body has good high-temperature resistance and heat dissipation effects, and can shield external ionization interference.

[0008] Furthermore, the inner walls of a number of heat dissipation openings are in contact with the outer walls of the corresponding heat dissipation rods.

[0009] Through the above technical solutions, the heat dissipation rods can conduct the heat inside the foam body and dissipate it through the heat dissipation openings.

[0010] Furthermore, a number of reinforcing ribs for improving the overall strength of the foam body are evenly installed inside the foam body. The number of the reinforcing ribs is in a "square" shape, and connecting rods are fixedly installed on one side of the number of the reinforcing ribs close to each other.

[0011] Through the above technical solutions, the cooperation between the reinforcing ribs and connecting rods can improve the overall strength of the foam body and prevent deformation or damage when subjected to external impact.

[0012] Furthermore, connecting seats are fixedly installed at both ends of the foam body, and an assembly frame is fixedly installed on the side wall of the connecting seat on the left side. A matching magnetic ring is fixedly installed on the inner wall of the assembly frame.

[0013] Through the above technical solution, the assembly frame and magnetic ring can work together to attract and connect with other foam bodies.

[0014] Furthermore, an installation body is fixedly installed on the side wall of the connecting seat located on the right side, and an adsorption seat is fixedly installed on the bottom of the installation body.

[0015] With the above technical solution, the mounting body and the adsorption seat can work together with the assembly frame and the magnetic ring for use.

[0016] Furthermore, the adsorption seat is hollow inside, and the adsorption seat and the magnetic ring can be adsorbed and fixed.

[0017] By employing the above technical solution, the hollow interior of the adsorption base can reduce its overall weight.

[0018] Furthermore, an adhesive layer is installed on the bottom wall of the shielding layer, and a release film is adhered to the bottom of the adhesive layer.

[0019] Using the above technical solution, the release film can be removed and then quickly adhered to the foam body. Beneficial effects

[0020] This invention provides a high-temperature resistant conductive foam. Compared with the prior art, it has the following advantages:

[0021] (1) The high-temperature resistant conductive foam can be attached to the top of the workpiece by peeling off the release film and moving the foam body through the adhesive layer. Another foam body is then attached to the magnetic ring in the inner wall of the mounting frame on the left side of the attached foam body. This allows for the connection of multiple foam bodies for use. Through the cooperation of the shielding layer, conductive cloth, flame retardant sleeve, heat insulation sleeve, heat sink, heat dissipation port, reinforcing rib, and connecting rod, the shielding layer can prevent external ionization interference. The conductive cloth gives the foam body good conductivity. The flame retardant sleeve and heat insulation sleeve give the foam body good high-temperature resistance and prevent spontaneous combustion. The heat sink and heat dissipation port can dissipate the heat inside the foam body to the outside, providing good heat dissipation. The reinforcing rib and connecting seat give the foam body good strength, preventing deformation and damage when subjected to pressure or external impact. Attached Figure Description
