Embedded aluminum foil foam

Abstract

The invention discloses embedded aluminum foil foam. The embedded aluminum foil foam includes a foam body and an aluminum foil coating layer, wherein the outer side of the foam body is coated with thealuminum foil coating layer; an embedment groove is formed in the foam body and includes an opening end and a tensioning end, wherein the opening end is located at one side of the foam body, and thetensioning end is located in the deep of the foam body; the aluminum foil coating layer further includes an embedded part, wherein the embedded part stretches into the tensioning end through the opening end of the embedment groove, and the end of the embedded part is matched with the tensioning end through a filling part. According to the embedded aluminum foil foam, the embedment groove is formedin the foam body so that the aluminum foil coating layer at the outer side can stretch into the embedment groove; the overall embedded aluminum foil foam can be inserted into a thin-wall flange structure of an electronic element and then is attached and fixed, so that the embedded aluminum foil foam is good in stability and does not easily fall; the embedded end of the aluminum foil coating layeris matched with the tensioning end through the filling part, therefore, the situation can be avoided that aluminum foil slips out, and a shielding effect is ensured.

Description

technical field [0001] The invention relates to an embedded aluminum foil foam. Background technique [0002] Aluminum foil foam is made of flexible pure aluminum foil and glass fiber composite aluminum foil cloth instead of conductive cloth to wrap flame-retardant foam. It has excellent metal shielding performance and high temperature resistance, and is often used in electronic components; the existing aluminum foil Most of the flame-retardant foam is a simple aluminum foil-wrapped structure. This kind of aluminum foil foam has the disadvantages that the aluminum foil is easy to loosen and easily damaged; in actual use, when it is necessary to install foam on the thin-walled flange structure of electronic components, Usually, two pieces of aluminum foil foam are separately installed on both sides of the thin wall, and then the two pieces of foam are bonded and fixed, but the shielding effect of this arrangement is poor, and the two pieces of foam are easy to be glued and se...
