Coil bobbins are disclosed 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.
