  • EMI shielding gasket having a consolidated conductive sheathing
    Patent number: 6462267
    Abstract: An electromagnetic interference (EMI) shielding gasket. The gasket is formed as having a resilient core member of an indefinite length which is sheathed in an electrically conductive fiber mesh member. A thermoplastic member is incorporated within the fiber mesh member for consolidating at least a portion of the fiber mesh member. The consolidation is effective to maintain the integrity of the fiber mesh member at an end of the gasket when the gasket is terminated to a determinable length.
    Type: Grant
    Filed: July 19, 1999
    Date of Patent: October 8, 2002
    Assignee: Parker-Hannifin Corporation
    Inventors: George H. Spies, Richard A. Hamel, Jonathan E. Mitchell, William Lionetta, James A. Bradley
  • Method of terminating an EMI shielding gasket
    Patent number: 5996220
    Abstract: Method of terminating at least one end of an EMI shielding gasket having an indefinite length. A resilient core member of an indefinite length is sheathed within an electrically conductive fiber mesh member. A thermoplastic member is incorporated within the conductive fiber mesh member, and then is heated to effect its melting which, in turn, effects the consolidation of at least a portion of the fiber mesh member. The gasket so formed then is terminated to a determinable length having an end through a consolidated portion of the fiber mesh member. The consolidated portion is effective to maintain the integrity of the fiber mesh member at the terminated end.
