Abstract
PURPOSE: The title shielding material having improved moldability, reliability to keep electric stability for a long period of time, and electromagnetic wave shielding action, by adding uniformly electrically-conductive material pieces to a synthetic resin.
CONSTITUTION: Thin pieces of an electrically-conductive material (e.g., aluminum) with a thickness of about 0.02mm in a constant amount are ejected from the nozzle to a thermoplastic synthetic resin in a molten state by heating and the pieces are distributed in the resin uniformly and cooled to give the desired shielding material. A connector wherein the shielding material as an external supporter is applied to a joint of a connector and a coaxial cable, or a cabinet, e.g., an electronic device, whose internal and external surfaces are coated with the shielding material prevents the electromagnetic wave generated in outer sources and absorbs the electromagnetic wave generated in inner sources, and exhibits improved effect.
EFFECT: The preparation of the shielding material is easier than a conventional method forming an electrically conductive thin film on the surface of a material, the release and bond removal of the electrically conductive material will not occur, and it has raised reliability.
