  • Patent number: 6653556
    Abstract: A conductive gasket includes: a non-conductive, elastic core; a flexible conductive cloth enclosing an outer surface of the core; a hot-melt adhesive inserted between the core and the conductive cloth to attach the core and the conductive cloth; a pressure sensitive adhesive (PSA) tape attached along the gasket to cover the ends of the conductive cloth; and a ridge formed on the PSA tape attached side of the conductive cloth. The conductive gasket is capable of forming a conduction path at all times between conductive members and enhances EMI/RFI shielding efficiency and contact reliability.

  • Patent number: 6355878
    Abstract: A clip type conductive gasket having a conductive metal finger strip that is fitted to a part of an electric or electronic apparatus to be electrically connected or electrically block electromagnetic interference (EMI) and particularly radio frequency interference (RFI). A conductive elastic body is dispensed on an upper portion of the conductive metal finger strip. According to the clip type conductive gasket, a physical binding force is increased, the electrical conductivity and the contact area is increased so that the contact resistance is lowered. Therefore, the manufacturing cost is lowered.
