Abstract
A bobbin assembly provides means for mounting two coils in concentric relationship with one another for use in electrical devices such as solenoids, relays, and transformers. The bobbin assembly comprises inner and outer hollow, cylindrical spools each having a coil of wire wound thereon prior to being assembled with one another by moving the inner spool into the hollow interior of the outer spool. Alignment members extending axially from the inner and outer spools engage one another to maintain the spools in their concentric relationship and also provide wire guide means routing the ends of the coil wires away from the spools and terminating them in a manner facilitating connection of the coils to associated electric circuits.
