Abstract
A solenoid actuator including a coil of electrically conductive wire wound about an axis, an enclosure for the coil, a receptacle carried by the enclosure for accommodating a mounting member of a device to be controlled by the solenoid actuator, a slideway carried by the enclosure extending transverse to the coil axis, and a fastener movable within the slideway for latching and unlatching the enclosed coil to the device to be controlled. The coil enclosure is a plastic encapsulation, the receptacle is an opening in a surface of the encapsulation, and the slideway is a chamber within the encapsulation intersecting the recess. The mounting member, which may be secured to a core tube within which the movable armature of the solenoid actuator is located, has an annular slot, and the fastener is a clip formed of sheet metal having edges which slide into the slot to latch the enclosed coil to the mounting member. The clip is formed with resilient detents for pressing the core tube against a stationary armature fixed within the solenoid coil. The clip is generally U-shaped, so that its arms straddle the mounting member, and the arms carry lugs which cooperate with shoulders within the slideway chamber to prevent complete removal of the clip from the slideway. The entry into the slideway is shaped to cooperate with the lugs so that the clip can be inserted into the slideway in only a single orientation.
