ABSTRACT:
Coil bobbins having flanged coil support portions provided with outboard terminal housings projecting beyond the flange rim and defining inwardly extending terminal-receiving cavities. The end walls of the housings are slotted to allow a wire to pass through the cavity in a circumferential direction relative to the winding axis in similar fashion to a turn of coiling. Bifurcated terminals pressed into the cavities in straddling relationship to the wire provide connections to the coil. A double bobbin has twin flanged coil support portions with bridging sections maintaining their physical separation. Terminal housings are provided on the bridging sections allowing wire to be first wound into a coil on one support portion, guided across the bridging section and passed through the cavity in a terminal housing, and then wound into a coil on the other support portion, all without interruption.
