Abstract: A control circuit for a gearmotor is located internal to a plastic gearbox to reduce handling damage and damage resulting from exposure to the environment. The control circuit includes a metal track which provides an electrical conductive path for input power to an electric motor and electrical components and thereby eliminates the need for a printed circuit board. The metal track includes a plurality of alternative control circuits paths, the appropriate circuit being chosen during assembly of the gearmotor by selectively piercing knock-out tabs in the metal track. The metal track includes locking receptacles for receiving switch and d.c. motor electrical terminals and further includes crimping receptacles for receiving electrical component lead wires. The metal track is located on the internal surface of the plastic gearbox cover by integrally molded posts and is secured to the cover by ultrasonically or heat staking the posts.

Abstract translation: 用于减速电机的控制电路位于塑料齿轮箱的内部，以减少由于暴露于环境而导致的操作损坏和损坏。 控制电路包括金属轨道，其提供用于向电动机和电气部件输入动力的导电路径，从而不需要印刷电路板。 金属轨道包括多个替代的控制电路路径，通过选择性地穿透金属轨道中的敲掉突片，在减速电机的组装期间选择适当的电路。 金属轨道包括用于接收开关和直流的锁定插座。 电机电气端子，还包括用于接收电气元件引线的压接插座。 金属轨道通过整体模制的柱位于塑料齿轮箱盖的内表面上，并通过超声波或热铆钉固定到盖上。
