Abstract

A circuit card retainer for securing a circuit card within a circuit card receiving channel to mitigate the possibility of a circuit card connector jarring loose from a motherboard slot during transit or other vibration or shock causing activity. The circuit card retainer securely retains an inner edge of the circuit card upon insertion of the circuit card, and allows the circuit card to be extracted only if the groove abutment is flexed away from the inner edge of the circuit card, thereby removing the obstruction caused by the groove abutment.

Claims

1. A circuit card retainer comprising

a surface plane having a groove for receiving an edge of a circuit card, and

said groove comprising an abutment wherein said abutment is movable to enable said abutment to be displaced upon insertion of the circuit card, and wherein said abutment prevents movement of the circuit card out of said circuit card retainer unless said abutment is moved independent of the circuit card and in a manner to permit such removal.

2. The circuit card retainer of claim 1, further comprising

a first and a second ridge parallel to each other and integral to said surface plane defining said groove for receiving the edge of the circuit card, and

said abutment is integral to a flexible portion of said groove such that said abutment allows the circuit card to be inserted into said groove by flexing away from the edge of the circuit card, and prevents the circuit card from being extracted from said groove unless said abutment is flexed away from the edge of the circuit card in a manner to permit such removal.

3. The circuit card retainer of claim 2 further comprising

a third and a fourth ridge parallel to each other and in vertical alignment with said first and second ridge and integral to said surface plane further defining said groove, and

said groove comprising an inclined surface which rises from said surface plane to a maximum surface level in the direction of said groove and then returns to said surface plane from the maximum surface level at approximately a perpendicular angle thereby forming said abutment.

4. The circuit card retainer of claim 3, further comprising

one or more tabs located on a side of said surface plane opposite said first and second ridge, wherein said tabs allow said circuit card retainer to be attached to an appropriate and corresponding surface within a computer system for receiving said tabs.

5. The circuit card retainer of claim 2, further comprising

a press tab integral to said flexible portion of said groove, said press tab providing a structure wherein the proper application of pressure on said press tab causes said abutment to flex away from the edge of the circuit card.

6. The circuit card retainer of claim 2, wherein said abutment can be positioned integrally to said flexible portion of said groove at various positions along said groove such that said circuit card retainer can accommodate circuit cards of varying height.

7. A circuit card retainer comprising

a surface comprising one or more circuit card receiving channels wherein each circuit card receiving channel comprises

a groove for receiving an edge of a circuit card, and

said groove comprising an abutment wherein said abutment is movable to enable said abutment to be displaced upon insertion of the circuit card, and wherein said abutment prevents movement of the circuit card out of said circuit card retainer unless said abutment is moved independent of the circuit card and in a manner to permit such removal.

8. The circuit card retainer of claim 7, further comprising

a first and a second ridge parallel to each other and integral to said surface plane defining said groove for receiving the edge of the circuit card, and

said abutment is integral to a flexible portion of said groove such that said abutment allows the circuit card to be inserted into said groove by flexing away from the edge of the circuit card, and prevents the circuit card from being extracted from said groove unless said abutment is flexed away from the edge of the circuit card in a manner to permit such removal.

9. The circuit card retainer of claim 8, further comprising

a third and a fourth ridge parallel to each other and in vertical alignment with said first and second ridge and integral to said surface plane further defining said groove, and

said second groove comprising an inclined surface which rises from said surface plane to a maximum surface level in the direction of said groove and then returns to said surface plane from the maximum surface level at approximately a perpendicular angle thereby forming said abutment.

10. The circuit card retainer of claim 8, further comprising

a press tab integral to said flexible portion of said groove, said press tab providing a structure wherein the proper application of pressure on said press tab causes said abutment to flex away from the edge of the circuit card.

11. The circuit card retainer of claim 8, wherein said abutment can be positioned integrally to said flexible portion of said groove at various positions along said groove such that said circuit card retainer can accommodate circuit cards of varying height.

12. The circuit card retainer of claim 8, wherein said surface can be located in various positions within a computer system such that said circuit card retainer can accommodate circuit cards of varying length.

13. A circuit card retainer comprising

a receiving groove for receiving an edge of a circuit card wherein said edge of said circuit card defines a plane perpendicular to the circuit card and said edge comprises a top corner, said receiving groove comprising an abutment wherein said abutment circumscribes said top corner of said circuit card edge when said circuit card is fully received in said receiving groove and thereby substantially prevents withdrawal of the fully received circuit card from the receiving groove,

said abutment being movable out of the plane defined by the circuit card edge to enable removal of said circuit card from the receiving groove.

14. A circuit card retainer comprising

a surface comprising one or more receiving grooves, each receiving groove for receiving an edge of a circuit card wherein said circuit card edge comprises a top corner, said receiving groove comprising an abutment wherein said abutment circumscribes said top corner of said circuit card edge when said circuit card is fully received in said receiving groove and thereby substantially prevents withdrawal of the fully received circuit card from the receiving groove,

said abutment being movable apart from the surface to enable removal of said circuit card from the receiving groove.
