Abstract

Abstract A card holder (10) for a card (11), such as a PCB, includes a bottom member (13) and a top cover (14) which easily snap together to enclose the card (11) therebetween. The bottom member (13) may be made from a precision hot-flow semi-solid aluminum forging operation, and the top cover (14) may be made as an aluminum stamping. The overall assembly of the card holder (10) has high mechanical strength and rigidity, and the top member (14) merely serves as a cover. A substantially complete EMI shielding is provided, and both members are hard anodized for electrical insulation. The card holder (10) is cost-effective, yet rugged and reliable, and the anodizing provides a pleasing product appearance. An injection molding operation is not necessary, and a separate plastic part is eliminated.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 112 words
A card holder for a card used in computers and related equipment comprising: a single unitary bottom member fabricated from a metal having a high strength modulus and adapted to serve directly as a rigid frame for a card; and a stamped top member adapted to be snapped over said bottom member after a card has been disposed in said bottom member to complete the assembly of the card holder, whereby upon disposing said card in said bottom member and assembling said card holder, said bottom member provides high mechanical strength and rigidity and said top member serves merely as a cover without being required to generate mechanical strength in the assembly.
Claim 2
Dependent Claim 112 words
A card holder for a card used in computers and related equipment comprising: a single unitary bottom member fabricated from a metal having a high strength modulus and adapted to serve directly as a rigid frame for a card; and a stamped top member adapted to be snapped over said bottom member after a card has been disposed in said bottom member to complete the assembly of the card holder, whereby upon disposing said card in said bottom member and assembling said card holder, said bottom member provides high mechanical strength and rigidity and said top member serves merely as a cover without being required to generate mechanical strength in the assembly.
Claim 3
Dependent Claim 23 words
The card holder of claim 1, wherein the unitary bottom member is formed as a hot-flow semi-solid precision forging of an aluminum material.
Claim 4
Dependent Claim 18 words
The card holder of claim 1, wherein the unitary bottom member is formed as a die-cast aluminum casting.
Claim 5
Dependent Claim 45 words
The card holder of claim 2, wherein the top member comprises an aluminum stamping, wherein the aluminum material of the members provides good EMI shielding, and wherein each of the members is hard anodized, thereby providing for electrical insulation between the card and the members.
Claim 6
Dependent Claim 12 words
The card holder of claim 4, wherein the card comprises a PCB.
Claim 7
Dependent Claim 54 words
The combination of claim 4, wherein the bottom member has respective longitudinal side ribs, each of which is provided with a longitudinal ledge, and wherein the bottom member further has a pair of spaced-apart transverse ribs communicating with the ledges, such that the card is supported upon the longitudinal ledges and transverse ribs, respectively.
Claim 8
Dependent Claim 54 words
The card holder of claim 4, wherein the top member has respective side edges, each of which is provided with a pair of spaced-apart hooks, and wherein the bottom member is provided with a pair of spaced-apart cooperating recesses receiving the hooks, such that the top member is snapped on to the bottom member.
Claim 9
Dependent Claim 21 words
The card holder of claim 4, further including a separate thin insulation layer disposed between the card and the bottom member.
