Apparatus, assembly and system for enhancing EMI shielding

An assembly for use in providing EMI shielding for a circuit card, the assembly comprising:

• a circuit card;
• a fastener;
• and, a shielding apparatus comprising:
• a body providing EMI shielding and including an attaching portion extending therefrom, the attaching portion has a proximal end portion with a folded segment, the proximal end portion having a planar segment extending in an opening in the body for controlling EMI leakage and positions the attaching portion so that the fastener can fasten the attaching portion to the circuit card such that a fastener head portion of the fastener is directly engaged in juxtaposed relationship with a first card surface so that the head portion does not extend generally beyond a predetermined distance from the first card surface.

An assembly for use in providing EMI shielding for a PCI card, the assembly comprising:

• a PCI card;
• a fastener;
• and, a shielding apparatus attached to the PCI card by the fastener;
• the apparatus comprising a body providing EMI shielding and including an attaching portion extending therefrom, the attaching portion has a proximal end portion with a folded segment, the proximal end portion has a planar segment extending in an opening in the body for controlling EMI leakage and positions, the folded segment positions the attaching portion so that the fastener fastens the attaching portion to the PCI card such that a head portion of the fastener is directly engaged with a first PCI card surface so that the head portion does not extend generally beyond a predetermined distance from the first PCI card surface.

An electronic enclosure providing for EMI shielding, the enclosure comprising:

• a housing assembly including an opening for allowing passage of a connector and/or wiring, and a shield member adapted to position and mount a circuit card adjacent the opening;
• wherein the shield member is an EMC shield member positioned within the enclosure adjacent the opening and constructed so as to retain an end portion of a circuit card assembly therein;
• and
• an assembly for use in providing EMI shielding for a circuit card, the assembly comprising:
• a circuit card;
• a fastener;
• and a shielding apparatus attached to the circuit card by the fastener;
• the apparatus comprising a body providing EMI shielding and including an attaching portion extending therefrom, the attaching portion has a proximal end portion with a folded segment, the proximal end portion has a planar segment extending in an opening in the body and the folded segment positions the attaching portion so that the fastener fastens the attaching portion to a circuit card such that a fastener head portion directly engages a card surface so that the head portion does not extend generally beyond a predetermined distance from the card surface.

A computer system comprising:

• an electronic enclosure providing for EMI shielding, the enclosure comprising:
• a housing assembly including an opening for allowing passage of cables and/or connectors, and a shield member adapted to position and mount a circuit card adjacent the opening;
• wherein the shield member is an EMC shield member positioned within the enclosure adjacent the opening and constructed so as to retain an end portion of a PCI card assembly therein;
• and
• an assembly for use in providing EMI shielding for a PCI card, the assembly comprising:
• a PCI card;
• a fastener;
• and, a shielding apparatus attached to the PCI card by the fastener;
• the apparatus comprising a body providing EMI shielding and including an attaching portion extending therefrom, the attaching portion has a proximal end portion, the proximal end portion has a planar segment extending in an opening in the body for controlling EMI leakage, the proximal end portion has a folded segment which positions the attaching portion so that the fastener fastens the attaching portion to the PCI card such that a fastener head portion is directly engaged in juxtaposed relationship with a card surface so as not to extend generally beyond a predetermined distance from the card surface.
