ABSTRACT:
An insulated coupling usable with a television tuner shaft or the like for electrically isolating the tuner shaft from the chassis of the television receiver includes a pair of flanged insulating bushings pressed into axially extending chambers formed in the ends of two coupled sections of the tuner shaft. A knurled pin fabricated from hardened steel or other strong material is pressed into the two bushings to hold the two sections of the shaft together with the two flanges of the bushings abutting to form an insulated section between the two coupled sections of the shaft.
