Abstract:
A shielded wiring system for high voltage AC current comprising;a flexible cable having a central current carrying electrical conductor, a symmetrical layer of insulation concentrically surrounding said central conductor, a symmetrical circumferential layer of shielding conductor surrounding said layer of insulation and a symmetrical outer sheath of insulation surrounding said shielding conductor;a fitting of conductive material having a passageway therethrough that receives said flexible cable therein, said fitting having at one end thereof an integral portion for use in attachment of the fitting to another piece of electrically conductive equipment and having at an opposite end thereof an integral crimpable thin wall tubular portion providing a portion of said passageway that receives said cable; anda short length flat bare conductive metal insert having a first portion positioned through a relatively small opening in an otherwise uninterrupted portion of said flexible cable outer sheath of insulation to conductively engage said cable circumferential layer of shielding conductor and having a second portion that remains exterior of said uninterrupted portion of said flexible cable outer sheath of insulation that conductively engages said fitting whereby said fitting is in electrical continuity with said cable circumferential layer of shielding conductor, said second portion of said conductive metal insert engaging said fitting integral reduced external diameter tubular portion and said fitting integral reduced external diameter tubular portion being readily inwardly compressed by means of crimping to thoroughly contact said conductive metal insert second portion to thereby ground said fitting to said cable circumferential layer of shielding conductor.
