Backplate for securing a circuit card to a computer chassis

A backplate for retaining a substrate to a computer chassis, comprising:

• a body having an elongated section and a top section orthogonal to the elongated section for attaching the backplate to the computer chassis;
• a first and second tab set aligned longitudinally on the elongated section;
• each tab set having at least a first tab and a second tab extending from the elongated section, the first and second tabs of each tab set being longitudinally offset and laterally spaced apart to define a slot for retaining the substrate;
• said first tab of each tab set including a first tang that extends into the slot for engaging a fastener hole on the substrate, and a distal contact surface for contacting a ground plane on the substrate;
• and
• said second tab of each tab set being curved to have a maximum deflection region extending into the slot and a rounded end that combines with the first tab to form an enlarged mouth for the slot.

A backplate for retaining a substrate to a computer chassis, comprising:

• a body, having an elongated section and a top section orthogonal to the elongated section for attaching the backplate to the computer chassis;
• a first and second tab set aligned longitudinally on the elongated section;
• each tab set having at least a first tab and a second tab extending from the elongated section, the first and second tabs of each tab set being longitudinally offset and laterally spaced apart to define a slot for retaining the substrate;
• said first tab of each tab set including a first tang that extends into the slot for engaging a first fastener hole on the substrate, and a distal contact surface contacting a grounding plane on the inserted substrate;
• and
• said second tab of each tab set including a second tang that extends into the slot for engaging a second fastener hole on the substrate.

A network circuit card assembly, comprising:

• a substrate having a plurality of fastener holes;
• a backplate having an elongated section, and a top section orthogonal to the elongated section for attaching the backplate to the computer chassis;
• a first tab set having a first and second tab, each tab extending from the elongated section, the first and second tabs being longitudinally offset and laterally spaced apart to define a longitudinal slot for retaining the network circuit card;
• and
• a first biased tang that is extended laterally from the first tab to engage one of the fastener holes on the substrate of the network circuit card.

A backplate for coupling a substrate to a computer chassis, the backplate comprising:

• an elongate body;
• a plurality of tab sets, each tab set including a plurality of tabs that extend from the elongate body and combine to form a longitudinal slot for retaining the substrate;
• and
• a plurality of biased tangs, each of the plurality of tangs being laterally extendible from one of the plurality of tabs in each of the plurality of tab sets to engage a fastener hole in the substrate.

A backplate for coupling a substrate to a computer chassis, the backplate comprising:

• an elongate body;
• a first tab extending from the elongate body;
• a second tab extending from the elongate body to form a longitudinal slot with the first tab for receiving the substrate;
• and
• a first tang that is extended from the first tab into the longitudinal slot, the tang being biased to retain the substrate when the substrate is received in the longitudinal slot.
