Abstract

A first planar prong adjacent to and parallel with, an exterior of the side of the enclosure. A second planar prong parallel to and spaced from an interior of the side of the enclosure and compress a first compressible gasket against the side of the enclosure. Furthermore, the second planar prong forms a first compartment between a first side of the second planar prong and the interior of the side of the enclosure, parallel to and spaced from an interior of the side of the enclosure. A planar base of the first planar prong and the second planar prong, adjacent to a cover of the enclosure. A first planar member having one end coupled perpendicular to a second side of the second planar prong and support a second compressible gasket in a second compartment formed between the planar member and the cover.

Claims (46)

1. A device for attenuating propagation of electromagnetic emissions when in an installed position of an enclosure that includes a cover and a side, the device comprising:

a two-prong member having:

a first planar prong substantially adjacent to and substantially parallel with an exterior of the side of the enclosure,

a second planar prong substantially parallel to and spaced from an interior of the side of the enclosure, configured to compress a first compressible gasket against the side of the enclosure, and forming a first compartment between a first side of the second planar prong and the interior of the side of the enclosure, and

a planar base of the first planar prong and the second planar prong substantially adjacent to the cover;

a first planar member having one end coupled substantially perpendicular to a second side of the second planar prong and configured to support a second compressible gasket in a second compartment formed between the planar member and the cover.

2. The device of claim 1 , further comprising:

a second planar member with a first end coupled to an end of the second planar prong, opposite the planar base and a second end coupled to a second end of the first planar member, opposite the one end of the first planar member.

3. The device of claim 1 , wherein the first compressible gasket is compressed to at least 40 percent of an initial height of the first compressible gasket and the second compressible gasket is compressed to at least 40 percent of an initial height of the second compressible gasket.

4. The device of claim 1 , wherein the device is a conductive material.

5. The device of claim 1 , wherein the first compressible gasket is coupled to the second planar prong and the second compressible gasket is coupled to the first planar member.

6. The device of claim 1 , wherein the first compressible gasket and the second compressible gasket are made of EMI shielding material.

7. A kit for attenuating propagation of electromagnetic emissions when in an installed position of an enclosure that includes a cover and a side, the kit comprising:

a first compressible gasket;

a second compressible gasket;

a device having:

a two-prong member having:

a first planar prong substantially adjacent to and substantially parallel with an exterior of the side of the enclosure,

a second planar prong substantially parallel to and spaced from an interior of the side of the enclosure, configured to compress a first compressible gasket against the side of the enclosure, and forming a first compartment between a first side of the second planar prong and the interior of the side of the enclosure, and

a planar base of the first planar prong and the second planar prong substantially adjacent to the cover;

a first planar member having one end coupled substantially perpendicular to a second side of the second planar prong and configured to support a second compressible gasket in a second compartment formed between the planar member and the cover.

8. The kit of claim 7 , the device further comprising:

a second planar member with a first end coupled to an end of the second planar prong, opposite the planar base and a second end coupled to a second end of the first planar member, opposite the one end of the first planar member.

9. The kit of claim 7 , wherein the first compressible gasket is compressed to at least 40 percent of an initial height of the first compressible gasket and the second compressible gasket is compressed to at least 40 percent of an initial height of the second compressible gasket.

10. The kit of claim 7 , wherein the device is a conductive material.

11. The kit of claim 7 , wherein the first compressible gasket is coupled to the second planar prong and the second compressible gasket is coupled to the first planar member.

12. The kit of claim 7 , wherein the first compressible gasket and the second compressible gasket are made of EMI shielding material.

13. A system for attenuating propagation of electromagnetic emissions, the system comprising:

an enclosure having:

a cover, and

a side;

a first compressible gasket;

a second compressible gasket;

a device having:

a two-prong member having:

a first planar prong substantially adjacent to and substantially parallel with an exterior of the side of the enclosure,

a second planar prong substantially parallel to and spaced from an interior of the side of the enclosure, configured to compress a first compressible gasket against the side of the enclosure, and forming a first compartment between a first side of the second planar prong and the interior of the side of the enclosure, and

a planar base of the first planar prong and the second planar prong substantially adjacent to the cover;

a first planar member having one end coupled substantially perpendicular to a second side of the second planar prong and configured to support a second compressible gasket in a second compartment formed between the planar member and the cover.

14. The system of claim 13 , the device further comprising:

a second planar member with a first end coupled to an end of the second planar prong, opposite the planar base and a second end coupled to a second end of the first planar member, opposite the one end of the first planar member.

15. The system of claim 13 , wherein the first compressible gasket is compressed to at least 40 percent of an initial height of the first compressible gasket and the second compressible gasket is compressed to at least 40 percent of an initial height of the second compressible gasket.

16. The system of claim 13 , wherein the device is a conductive material.

17. The system of claim 13 , wherein the first compressible gasket is coupled to the second planar prong and the second compressible gasket is coupled to the first planar member.

18. The system of claim 13 , wherein the enclosure is a conductive material.

19. The system of claim 13 , wherein the first compressible gasket and the second compressible gasket are made of EMI shielding material.
