Abstract

The EMI shielding gasket includes an opening therein such that the gasket can be fitted around a shell portion of an electrical connector used on the chassis of an electronic apparatus. The gasket opening, which is defined by an interior edge, includes a plurality of teeth-like portions which are adapted and sized to grip a shell portion of the connector, holding the gasket in place on the connector during handling of the connector and/or assembly of the electronic device.

Claims

1. A shielding gasket for use with and metal shell electrical connectors assembly comprising:

a connector adapted for providing electric signal connection to and from an electronic apparatus, said connector having a smooth metal shell portion; and

a gasket member having an opening therein adapted so that the gasket member fits around the smooth metal shell portion of the electrical connector, the gasket member further adapted to fit between a facing surface of the connector and an interior surface of a chassis panel of the electronic apparatus, wherein the opening of the gasket member is defined by an interior edge having at least one edge portion therealong having a sharp element configured and arranged to bite into the smooth connector shell portion sufficiently to hold the gasket member in place on the connector during handling of the connector.

2. An article of claim 1, wherein said interior edge further comprises a plurality of edge portions positioned along said interior edge.

3. An article of claim 2, wherein all of said edge portions further comprise a sharp element.

4. An article of claim 1, wherein the gasket member is stainless steel.

5. An article of claim 1, wherein the gasket member is copper.

6. An article of claim 1, wherein said interior edge further comprises at least two opposing edge portions along said interior edge, the two opposing edge portions, respectively, being located on opposite sides of said opening, thereby opposing each other.

7. An article of claim 1, wherein the gasket member includes a gasket central longitudinal portion and two gasket longitudinal edge portions, the gasket longitudinal edge portions both being positioned at an angle relative to the central longitudinal portion.

8. An article of claim 6, wherein at least one of said opposing edge portions further comprises a sharp element.

9. An article of claim 1, wherein said sharp element is a sharp point.

10. An article of claim 1, wherein said sharp element is a tooth.

11. An article of claim 1, wherein said sharp element is a barbed element.

12. A shielding gasket for use with metal shell electrical connectors used with an electronic apparatus, the connectors providing electrical signal connection to and from the electronic apparatus, comprising:

a gasket member having an opening therein adapted so that the gasket member fits around a shell portion of the electrical connector, the gasket member further adapted to fit between a facing surface of the connector and an interior surface of a chassis panel of the electronic apparatus, wherein the opening of the gasket member is defined by an interior edge having at least one edge portion therealong having a sharp element configured and arranged to bite into the connector shell portion sufficiently to hold the gasket member in place on the connector during handling of the connector, wherein each side of the base of the sharp element is situated below and spaced from the interior edge portion which defines the opening of the gasket member and the point of the sharp element is situated above the interior edge portion which defines the opening of the gasket member.

13. A shielding gasket for use with metal shell electrical connectors used with an electronic apparatus, the connectors providing electrical signal connection to and from the electronic apparatus, comprising:

a gasket member having an opening therein adapted so that the gasket member fits around a shell portion of the electrical connector, the gasket member further adapted to fit between a facing surface of the connector and an interior surface of a chassis panel of the electronic apparatus, wherein the opening of the gasket member is defined by an interior edge having at least one edge portion therealong having a sharp element configured and arranged to bite into the connector shell portion sufficiently to hold the gasket member in place on the connector during handling of the connector, wherein said gasket member further includes a gasket central longitudinal portion and two gasket longitudinal edge portions, the gasket longitudinal edge portions both being positioned at an angle relative to the central longitudinal portion.
