Abstract
An electromagnetic interference shielding gasket extends through a slot in a face plate assembly bracket arm from the underside thereof. The gasket is secured to the underside of the bracket arm to avoid the problem of the gasket peeling from the bracket arm when circuit card assemblies are inserted into and removed from slots in a shelf unit.
Claims6
In an electronic system having a shelf unit adapted to hold in respective parallel slots a plurality of circuit card assemblies side by side in a parallel array, wherein each circuit card assembly includes a circuit card and a face plate assembly, wherein each face plate assembly includes an elongated conductive C-shaped bracket having a pair of spaced parallel arms and a transverse spine connecting the pair of arms, and wherein the bracket is mounted to the circuit card so that an edge of the circuit card is adjacent to the transverse spine, a first of said arms is adjacent to a first side of the circuit card and a second of said arms is spaced from the second side of the circuit card, the improvement comprising:
- each bracket second arm is formed with at least one elongated slot having a major axis parallel to the circuit card edge;
- a respective conductive gasket extends through each elongated slot at a sufficient distance away from the respective circuit card to engage the first arm of the face plate assembly held in a next adjacent one of the slots of the shelf unit;
- and
- each gasket is secured to the bracket second arm along that surface of the bracket second arm which faces the respective circuit card.
In an electronic system having an enclosure with an aperture adapted to be closed by at least two components, wherein the periphery of the aperture lies substantially in a plane, wherein each component is associated with and mounted to a respective elongated conductive C-shaped bracket having a pair of spaced parallel arms and a transverse spine connecting the pair of arms, and wherein the transverse spine lies parallel to the plane and the bracket arms cross the plane when the respective component and associated bracket is mounted in the enclosure, the improvement comprising:
- each bracket second arm is formed with at least one elongated slot having a major axis which is parallel to the plane;
- a respective conductive gasket extends through each elongated slot at a sufficient distance away from the bracket second arm to engage a bracket first arm of a next adjacent component mounted in the enclosure;
- and
- each gasket is secured to the bracket second arm along that surface of the bracket second arm which faces the respective bracket first arm.
