Abstract

A gap filler member apparatus for blocking air flow through a gap existing between an edge of a first electronics board and a surface of a second electronics board that is disposed generally perpendicular to the first electronics board, where the first and second electronics boards are coupled by at least one pair of connectors and disposed within an electronics equipment enclosure, to block air flow through the gap. The apparatus has at least one rib extending therefrom, with the base portion being secureable to the surface of the second electronics board. A rib extends away from the base portion and has a height approximately equal to a height of the gap, and a length at least as long as a length of the gap so that the rib at least substantially blocks air flow through the gap.

Claims

1. A gap filler member apparatus for blocking air flow through a gap existing between an edge of a first electronics board and a surface of a second electronics board that is disposed generally perpendicular to said first electronics board, where the first and second electronics boards are coupled by at least one pair of connectors and disposed within an electronics equipment enclosure, to block air flow through the gap, the apparatus comprising:

a base portion having at least one rib extending therefrom, said base portion adapted to be secured to said surface of said second electronics board; and

said rib extending away from said base portion and having a height approximately equal to a height of said gap formed between said first and second electronics boards, and a length of the rib being at least as long as a length of the gap, such that said rib at least substantially blocks the gap to prevent air flow through the gap.

2. The apparatus of claim 1, wherein said surface of said base portion is adapted to be adhered to said second electronics board via an adhesive.

3. The apparatus of claim 1, wherein said base portion includes an additional rib spaced apart from said rib and extending generally parallel to said rib, and having dimensions at least substantially equal to said rib, to block an additional gap existing between an additional electronics board coupled to said second electronics board adjacent to said first electronics board.

4. The apparatus of claim 3, wherein said base portion, said rib and said additional rib form a U-shape when viewed from an end of said apparatus.

5. The apparatus of claim 1, wherein said base portion includes:

a cutout to enable a portion of said pair of connectors to project therethrough when said connectors are engaged with one another; and

wherein portions of said base portion extend from opposite sides of said cutout so that said apparatus may be placed flush against said second electronics board and over said engaged connectors.

6. The apparatus of claim 5, wherein the base portion is secured to the second electronics board.

7. The apparatus of claim 1, wherein said base portion includes:

a cutout having dimensions sufficient to enable a portion of said pair of connectors to project therethrough when said connectors are engaged with one another; and

an additional rib spaced apart from said rib such that said base portion, said rib and said additional rib form a U-shape when viewed from one end of the apparatus; and

wherein the rib and additional rib extend perpendicularly from said base portion along a full length of said base portion so that said cutout is positioned at an intermediate point along a length of said base portion.

8. The apparatus of claim 1, wherein the apparatus comprises an integrally formed component formed from plastic.

9. The apparatus of claim 1, wherein the apparatus simultaneously blocks said gap and an additional gap, wherein said gap and said additional gap are present on opposite sides of said pair of connectors when said pair of connectors are coupled together.

10. A gap filler member apparatus for blocking air flow through a gap existing between an edge of a first electronics board and a surface of a second electronics board that is disposed generally perpendicular to said first electronics board, where the first and second electronics boards are coupled by a pair of connectors and disposed within an electronics equipment enclosure, to block air flow through the gap, the apparatus comprising:

a base portion having a pair of ribs extending perpendicularly therefrom, said base portion adapted to be secured to said surface of said second electronics board such that said ribs extend on opposite sides of said pair of connectors when said pair of connectors is coupled together; and

said ribs extending away from said base portion and having a height approximately equal to a height of said gap formed between said first and second electronics boards, and a length of each said rib being at least as long as a length of the gap, such that one of the ribs blocks the gap to prevent air flow through the gap.

11. The apparatus of claim 10, wherein the apparatus has a U-shape when viewed from one end thereof.

12. The apparatus of claim 11, wherein the apparatus includes a cutout formed in said base portion between said pair of ribs.

13. The apparatus of claim 12, wherein the cutout has dimensions enabling said pair of connectors to project therethrough when said apparatus is positioned adjacent said second electronics board.

14. The apparatus of claim 10, wherein the apparatus comprises an integrally formed component.

15. The apparatus of claim 10, wherein a first one of the pair of ribs blocks the gap, and wherein a second one of the pair of ribs blocks an additional gap formed by an additional first electronics board mounted on said second electronics board.

16. A method for blocking air flow through a gap existing between an edge of a first electronics board and a surface of a second electronics board that is disposed generally perpendicular to said first electronics board, where the first and second electronics boards are coupled by at least one pair of connectors and disposed within an electronics equipment enclosure, the method comprising:

providing a base portion having at least one rib extending generally perpendicular from the base portion;

positioning said base portion adjacent said surface of said second electronics board; and

providing said rib with a height approximately equal to a height of said gap formed between said first and second electronics boards, and a length at least as long as a length of the gap; and

using said rib to at least substantially block the gap to prevent air flow through the gap.

17. The method of claim 16, wherein said providing a base portion having at least one rib further comprises providing a base portion having a pair of parallel ribs extending generally parallel to one another.

18. The method of claim 17, further comprising securing said base portion to said second electronics board.

19. The method of claim 16, wherein said providing a base portion having at least one rib comprises providing an integrally formed component having said rib and an additional rib extending perpendicularly from said base portion.

20. The method of claim 19, further comprising forming said base portion with a cutout having dimensions enabling said connectors to project through the cutout.
