Slotted fabric over foam electromagnetic interference gaskets

1. A gasket of indefinite length for the mitigation of electromagnetic interference (EMI), the gasket comprising a series of sections of resiliently compressible core material wrapped in an electrically-conductive outer layer, each section having a base, the sections joined at their bases by strips of the electrically-conductive outer layer, wherein:

the electrically-conductive outer layer is electrically-conductive metallized fabric, and the resiliently compressible core material is a foam core;

the electrically-conductive metallized fabric is adhered to the foam core by way of an adhesive;

the gasket further comprises a bottom;

the electrically-conductive metallized fabric is wrapped around the foam core such that the electrically-conductive metallized fabric comprises two bottom portions on the bottom of the gasket, where the bottom portions do not meet and thus result in a gap therebetween; and

the gasket further comprises a strip of pressure sensitive adhesive adhered to the bottom of the gasket along its length, the strip of pressure sensitive adhesive covering the gap between the bottom portions of the electrically-conductive metallized fabric.

2. The gasket of claim 1 , wherein the spaces between adjacent sections are slots, the slots and the sections each having respective lengths, and wherein the ratio of the length of the section to the length of the slot is 1:1 or greater.

3. The gasket of claim 2 , wherein the ratio of the length of the section to the length of the slot is 2:1 or greater.

4. The gasket of claim 3 , wherein the ratio of the length of the section to the length of the slot is 3:1.

5. The gasket of claim 2 , wherein each section of conductive outer layer in the slots further comprises at least some residual foam.

6. The gasket of claim 2 , wherein the gasket is substantially free of halogen, and/or wherein the gasket further comprises an effective amount of flame retardant so as to achieve a flame retardance rating pursuant to the Underwriters Laboratories Standard No. 94 of V0.

7. The gasket of claim 1 , wherein the gasket is substantially free of halogen, and/or wherein the gasket further comprises an effective amount of flame retardant so as to achieve a flame retardance rating pursuant to the Underwriters Laboratories Standard No. 94 of V0.

8. The gasket of claim 1 , each section further comprising a face having the shape of a sideways capital D, the straight portion of the capital D being the base of the section.

9. An electronic device including the gasket of claim 1 .

10. A reel including the gasket of claim 1 reeled thereon.

11. An EMI shielding gasket of indefinite length comprising a resilient foam core wrapped in an electrically-conductive outer layer, the gasket having a substantially flat bottom of the electrically-conductive outer layer, the gasket further comprising a series of slots, wherein each slot is a gap in the gasket where the substantial majority of the resilient foam core and all the electrically-conductive outer layer except that which comprises the bottom of the gasket have been cut and removed from the gasket, wherein:

the electrically-conductive outer layer is electrically-conductive metallized fabric adhered to the resilient foam core by way of an adhesive, and wherein the gasket further comprises a bottom and a strip of pressure sensitive adhesive adhered to the bottom of the gasket along its length; and

the electrically-conductive metallized fabric is wrapped around the resilient foam core such that the electrically-conductive metallized fabric comprises two bottom portions on the bottom of the gasket, wherein the bottom portions do not meet and thus result in a gap therebetween, wherein the strip of pressure sensitive adhesive covers the gap between the bottom portions of the electrically-conductive metallized fabric.

12. The gasket of claim 11 , wherein the gasket further comprises a face having the shape of a sideways capital D, the straight portion of the capital D being a base of the gasket.

13. An EMI shielding gasket of indefinite length comprising a resilient foam core wrapped in an electrically-conductive metallized fabric that is adhered to the resilient foam core by way of an adhesive, the gasket having a substantially flat bottom of the electrically-conductive metallized fabric, the gasket further comprising a series of slots, wherein each slot is a gap in the gasket where the substantial majority of the resilient foam core and all the electrically-conductive metallized fabric except a bottom portion of the electrically-conductive metallized fabric that defines the substantially flat bottom of the gasket have been cut and removed from the gasket, wherein:

the slots and the sections each having respective lengths;

the ratio of the length of the section to the length of the slot is 1:1 or greater;

each section of the electrically-conductive metallized fabric in the slots further comprises at least some residual foam;

the gasket is substantially free of halogen; and

the gasket comprises an effective amount of flame retardant so as to achieve a flame retardance rating pursuant to the Underwriters Laboratories Standard No. 94 of V0;

wherein the electrically-conductive metallized fabric is wrapped around the resilient foam core such that the bottom portion of the electrically-conductive metallized fabric comprises two bottom portions that define the substantially flat bottom of the gasket;

wherein the bottom portions of the electrically-conductive metallized fabric do not meet and thus result in a gap therebetween; and

wherein the gasket further comprises a strip of adhesive adhered to the substantially flat bottom of the gasket along its length, the strip of adhesive covering the gap between the bottom portions of the electrically-conductive metallized fabric.

14. The gasket of claim 13 , wherein the residual foam has a height substantially the same as a thickness of the electrically-conductive metallized fabric.

15. The gasket of claim 13 , wherein the slots extend across an entire width of the gasket.

16. The gasket of claim 13 , wherein the slots have open end portions along each side of the gasket.

17. The gasket of claim 13 , wherein the slots extend across an entire width of the gasket such that the slots have open end portions along each side of the gasket.
