1. A coil bobbin comprising:
- a tubular support member;
a pair of coaxial spaced coil bobbins and at least one coaxially spaced metallic washer located between each of said bobbins, each of said bobbins and said metallic washer being circumferentially supported by said tubular support member;
one of said bobbins comprising a first bobbin members, said bobbin members further including a radially extending flange portion, the flange portion of said first bobbin members being seated adjacent said washer, said flange portion and said washer including interlocking means preventing relative rotation of said flange portion and said washer;
the other of said bobbins including a second bobbin member, and wherein a flange of said other bobbin member has an outer surface facing said washer and is in non-rotational relationship therewith, and a radial channel being formed in said flange for directing a coil winding lead wire outwardly from said coil bobbin structure.

Abstract
A coil bobbin structure comprising a series of axially spaced bobbin members including integrally formed tubular base portions supported on a tubular support member. The base portions each have edges facing one another and including stepped edged portions cooperating to provide interlocking structure for resisting relative rotation of the bobbin members and the tubular support member. The bobbin members each include radially extending flanges arranged to receive entering and exiting coil lead wires and to route the lead wires along a longitudinal path extending across a coil wound on the structure.
