  • Actuator
    Patent number: 9030059
    Abstract: An actuator includes a stator and a movable component movably mounted in the stator. The stator includes a yoke, a printed circuit board disposed at one axial end of the yoke, a bobbin mounted inside the yoke, windings wound about the bobbin; and multiple terminals mounted to the bobbin to electrically connect the windings ends to the printed circuit board. The bobbin includes a plurality of spaced extending portions extending towards the printed circuit board. The terminals are mounted to a respective end of the extending portions of the bobbin that face the printed circuit board. The terminals are spaced from the yoke. A free length of the terminal between the bobbin and the printed circuit board is short enough to avoid bending which may result in a short circuit between the terminals and the yoke.
