Title: Back wire ground clamp
Inventor: BALABAN DAVID B
IPC: H01R4/30
Filed: 2004-10-01
Abstract: The invention here disclosed is a back wire ground clamp for a wiring device such as a switch or receptacle having a ground strap which supports an outwardly projecting ground lug having a front edge and adapted to receive a ground connection. The ground lug is coupled to a clamp plate by means of a screw which passes through a clearance opening in the clamp plate and is threaded into a receiving opening in the ground lug. The clamp plate supports a blocking tab which extends downward below the front edge of the ground lug and extends side ways for a distance which is less than the length of the front edge of the ground lug. The blocking tab prevents the clamp plate from rotating relative to the ground lug as the screw is tightened and defines an opening between the clamp plate and the ground lug along the front edge of the ground lug into which a single ground wire can be inserted.

Abstract: A heatable article, e.g. a heatable windshield, having a generally trapezoidal shape has a conductive member, e.g. a conductive coating, between and in contact with a pair of spaced bus bars having different lengths. Selected portions of the coating between the bus bars are segmented to reduce the difference in watt density between the coatings at the bus bars when current moves through the coating. In one non-limiting embodiment, the width of the segments at the longer bus bar is less than the width of the segments at the longer bus bar. With this configuration, the watt density at the bottom of the windshield is increased to more efficiently remove ice and snow. In another non-limiting embodiment, the coating has a communication window to pass frequencies of the electromagnetic spectrum, e.g. RF frequencies, to obtain information from within the vehicle. The coating surrounding the conductive window has break lines to segment the coating to eliminate hot spot around the periphery of the communication window.
