Abstract
The present invention provides cables having a body that is surrounded by a vacuum metallized layer. The metallized layer can be grounded with a metallized thermoform connector to prevent the release or impingement of harmful EMI radiation. Optionally, an insulating top coating can be disposed over the metallized layer over the cable body.
Claims40
A method of shielding and grounding a cable, the method comprising:
- providing conductive leads encapsulated within a dielectric layer;
- applying a metallized layer around the dielectric layer;
- and
- coupling a metallized thermoform connector to the metallized layer, wherein the metallized thermoform can be electrically coupled to a grounded housing.
A shielded cable comprising:
- a cable body comprising electrical conductors disposed within an insulating substrate;
- a vacuum metallized shielding layer disposed over the insulating substrate, and
- a metallized thermoform connector coupled to an end portion of the cable body and electrically coupled to the vacuum metallized layer, wherein the connector can be electrically coupled to a grounded housing so as to ground the shielding layer and connector.
A method of shielding a cable from EMI and RFI radiation, the method comprising:
- providing conductive leads disposed within a dielectric;
- thermally vaporizing a metallized layer around the dielectric;
- and
- grounding the metallized layer to a grounded housing.
A shielded cable comprising:
- a conductive lead encapsulated within a dielectric;
- a polymer layer surrounding the dielectric;
