Abstract
A coil for use in the voltage section of the electromagnet in electromechanical utility watthour meters comprises a thermoplastic bobbin, a length of wire, and two terminals. The bobbin has an upper flange and a lower flange connected by a central, hollow core. The upper flange supports two terminal mounting boxes in which terminals are inserted. The first and second leads (i.e., wire ends) are electrically and mechanically isolated from each other in order for the coil to withstand high voltage power surges. The upper flange also supports a step that has a recessed, side profile that guides the path of the wire to the core without introducing sharp bends or turns into the wire. Excess length of the first and second ends of the wire length are secured to tie off posts that are located on the top of the terminal mounting boxes. These posts, along with the excess wire, are removed when the terminals are inserted into the mounting boxes.
