For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] like Figures 1 to 3 As shown, the utility model provides a flame-retardant conductive foam, including a foam body 100, and a clip 200 installed on the foam body 100, the foam body 100 includes a foam layer 110, a flame-retardant layer 120 located outside the foam layer 110, a reinforcement layer 140 located outside the flame-retardant layer 120, a heat-resistant layer 130 located outside the reinforcement layer 140, and a conductive cloth layer 150 located outside the heat-resistant layer 130, the flame-retardant layer 120 is wrapped in the foam layer 110, the reinforcement layer 140 is wrapped in the flame-retardant layer 120, the heat-resistant layer 130 is wrapped in the reinforcement layer 140, the conductive cloth layer 150 is wrapped in the heat-resistant layer 130, the clip 200 is clipped to the outer surface of the conductive cloth layer 150, and the clip 200 is made of elastic material. The provided clip 200 can be used to splice multiple foam bodies 100. The splicing is simple and convenient, and the number of splicing can be selected according to needs. It has strong applicability and avoids waste. The provision of the soft magnetic sheet 300 makes it easy to adsorb the foam body 100 on an object, which is easy to disassemble and assemble without leaving any traces of bonding.
[0023] The clamping member 200 is arranged in a cross shape. The clamping member 200 is provided with four clamping slots 210 . The four clamping slots 210 are arranged in an L shape. The clamping member 200 is clamped on the foam body 100 through the clamping slots 210 .
[0024] There are multiple clamping parts 200 and multiple foam bodies 100, and multiple clamping parts 200 are respectively clamped at multiple corners of the foam body 100. Multiple foam bodies 100 are clamped by multiple clamping parts 200. When a larger area of anti-static protection is required, multiple foam bodies 100 can be connected by using multiple clamping parts 200 to increase the use area.

[0025] The diameter of the slot 210 increases from the outside to the inside, the longitudinal section of the slot 210 is trapezoidal, and the diameter of the outer side of the slot 210 is smaller than the thickness of the foam body 100. Since the clamping piece 200 is made of elastic material and the diameter of the slot 210 increases from the outside to the inside, when a corner of the foam body 100 is installed in the slot 210, the two sides of the slot of the clamping piece 200 will be pressed against the foam body 100 by elastic force due to the elasticity of the clamping piece 200, thereby ensuring the stability of the foam body 100 when splicing.
[0026] It also includes a soft magnetic sheet 300 installed on the foam body 100. The soft magnetic sheet 300 is adhered to the outer surface of the conductive cloth layer 150. There are multiple soft magnetic sheets 300 and they are arranged at intervals.
