Electrical contact mechanism for ultrasonic transducers on fasteners
First Claim
1. An electrical contact mechanism for electrically connecting electronic circuitry cabling to an ultrasonic transducer which can be alternatively embedded in, permanently attached to, or temporarily attached to a fastener, said transducer providing a contact surface on said fastener, said electrical contact mechanism being positioned within a fastener tightening tool and making said electrical connection when said tightening tool is positioned on said fastener, comprising:
- a first electrically isolated conduction path through said tightening tool;
a first electrical connector on a first end of said first conduction path, said first electrical connector having a protruding movable pin spring biased outwardly and being fixed so as not to rotate relative to the tool; and
a second electrical conduction path through said tightening tool.

Abstract
An electrical contact structure for making and maintaining an electrical connection through a rotatable tool head is provided. A low cost contact probe assembly can be incorporated into the drive of various conventional tightening tools to extend onto the head of a fastener to make and maintain electrical contact therewith while the head is being operated upon by the socket or gripping means of the tightening tool. This contact probe assembly includes an insulated and shielded electrically conductive tube.
