ABSTRACT:
A molded plastic coil bobbin having means for securing the end lead of the coil within a groove provided in an end flange of the bobbin. The groove tapers outwardly from the cylindrical tube of the bobbin to the outer periphery of the end flange. The bobbin terminals are on each side of the groove. The flange has thin top and bottom walls above and below the groove. The end lead of the coil passes through this groove in passing from one terminal to the cylindrical tube of the bobbin. Radially extending ribs protrude downwardly and upwardly, respectively, from the top and bottom walls of the flange and serve to anchor or restrain the wire in a serpentine path in its passage through the flange. This damps vibrations that might be set up in the wire and thus minimizes the prospects that the wire will be broken due to vibrations.
