Abstract
Abstract A fluorescent lamp ballast includes a generally flat base upon which a core and coil subassembly is mounted and covered by a ballast case. A connector bar is mounted in the forward end of the ballast case and includes a plurality of sockets having terminal pins mounted therein for selectively receiving a wiring harness. The opposing ends of the terminal pins are electrically connected to a terminal strip which is mounted to the core and coil subassembly. The terminal strips have conductors electrically connected thereto which extend to termination points on the core and coil subassembly. A second series of terminal strips is mounted to the opposite end of the core and coil subassembly, and is electrically connected to a resistor and capacitor combination. A second embodiment of the ballast augments the first embodiment with an end connector bar mounted in the rearward end of the ballast case. A second version of a terminal strip, in the second connector bar, is designed to electrically connect terminal pins to either a conductor from the appropriate coil or to "passed through" connections from terminals at the forward end. A third version of the ballast utilizes the second embodiment of the terminal strip at the forward end of the ballast case to permit rearrangement of the resistor and capacitor combination to the forward end.
