Abstract
A backplate, or network circuit card assembly having a backplate is provided having an elongated section with one or more stem sections extending therefrom in a first direction. Each stem section includes heads that extend in a second direction. The heads may be positioned from an unbiased position to a biased position, where the biased position brings the heads into sufficient proximity with one another to allow the combined heads to pass through a hole of the printed circuit card. Once through, the heads are released to secure the printed circuit card with the stem section. The heads may also provide a surface that contacts a grounding plane of the printed circuit card.
Claims34
A backplate for retaining a substrate to a computer chassis, comprising:
- a body having an elongated section, and a top section substantially perpendicular to the elongated section for attaching the backplate to the computer chassis;
- a first stem section extending from the elongated section in a first direction;
- and
- a first and second head extending from the first stem section in a second direction, each head having a distal tip section that deflects from an unbiased position to a biased position that is proximate the other head, the first and second head each being dimensioned to fit within a hole on the substrate when biased towards one another to secure the substrate to the first stem section.
A backplate for retaining a substrate to a computer chassis, comprising:
- a body having an elongated section, and a top section substantially perpendicular to the elongated section for attaching the backplate to the computer chassis;
- a top stem section extending from the elongated section in a first direction and including a first and second stem, said first and second stem of the top stem section each having a head that extends in a second direction;
- a bottom stem section extending from the elongated section in the first direction and including a first and second stem, said first and second stem of the bottom stem section each having a head that extends in the second direction;
- the head of the first and second stems in each stem section being spaced apart, each head able to deflect from an unbiased position distal to the other head to a biased position proximate to the other head, the heads of each stem section combining to insert into a hole of a substrate when in the biased position.
A network circuit card assembly, comprising:
- a substrate having a plurality of holes;
- a backplate having an elongated section, and a top section substantially perpendicular to the elongated section for attaching the backplate to the computer chassis;
- a top stem section extending from the elongated section in a first direction and including a first and second stem, said first and second stem of the top stem section each having a head that extends in a second direction;
- a bottom stem section extending from the elongated section in the first direction and including a first and second stem, said first and second stem of the bottom stem section each having a head that extends in the second direction;
- the head of the first and second stems in each stem section being spaced apart, each head able to deflect from an unbiased position distal to the other head to a biased position proximate to the other head, the heads of each stem section combining to insert into the hole of the substrate when in the biased position.
