Actuator assembly

Abstract

The present invention relates to an actuator assembly, and provides an actuator assembly comprising: an upper case; a lower case; an actuator interposed between the upper and the lower cases; a cam coupled to the actuator; and a shutter connected to the cam, in which the cam includes protrusions and recesses, which are alternately formed at an interval of 90°, a hook is provided of which one end is disposed so as to alternately come into contact with the protrusions and the recesses according to a rotation of the cam, the other end is coupled to a spring, a longitudinal middle protrudes so as to form a touch part, and a hook shaft is coupled to a portion between the touch part and the other end of the hook, and a single microswitch is further provided at an upper side of the cam in order to stop an operation of the actuator in accordance with contact with the touch part. According to the present invention, the actuator assembly has a simple structure, and may be accurately controlled, and may achieve excellent sealing performance and improvement in durability, and because the actuator assembly may be controlled using the single microswitch, a reduction in cost and in fraction defective may be achieved.
