  • Patent number: 4937547
    Abstract: A ballast assembly for a fluorescent lighting fixture has a magnetic core, a primary winding and a secondary winding, both windings mounted on a central leg of the core, with a shunt disposed between the windings to prevent a flux generated by the primary winding from coupling with the flux generated by the secondary winding. The ballast further includes a shunt retaining clip disposable between the windings, the clip including a essentially U-shaped wall having a pair of upright portions and a crossover portion, a bottom ledge attached to the crossover portion for accepting the shunt. A spring arm extends between the pair of upright wall portions of the U-shaped wall with the spring arm sized to resiliently engage a top surface of the central core leg.

  • Patent number: 4853667
    Abstract: A wire bobbin (1) for use with inductive devices is disclosed having a central core (2) about which a wire is windable, with side walls (3) and (4) oppositely disposed about the core for retaining the wire thereon. A coil of wire, wound about the core, has a wire end (20) extending through at least one side wall. The side wall further includes a first channel (7) sized to retain a lead wire (21) therein, with the channel open at both ends. A second channel (13), which is preferably directly adjacent to the first channel, communicates through an open end (9) with the first channel. The lead wire is then inserted into the first channel, with a stripped end (22) extending into the second channel. The stripped end is combined with the magnet wire end, permanently joined, such as by dip soldering, and then bent into position within the second channel.
