US 2014/0368938 A1 · MOTOR FOR DRIVING LENSES

Abstract

Disclosed is a motor for driving lenses. The motor includes a case, a yoke fixed in the case, a magnet fixed in the yoke, a carrier equipped with lenses and installed in the magnet such that the carrier moves up and down within the magnet, a coil coupled with the carrier, in which the coil cooperates with the magnet to move up and down the carrier, a spring unit including first and second springs having arc shapes and being separated from each other while forming a ring shape as a whole, in which an outer peripheral surface of the spring unit is fixed to the case, an inner peripheral surface of the spring unit is fixed to the carrier to elastically support the carrier, and a lead wire of the coil is connected to the spring unit so that external power is supplied to the coil, a spacer supporting the outer peripheral surface of the spring unit, and a terminal provided on the spacer, in which one side of the terminal protrudes downward by passing through a bottom of the case to make connection with the spring unit and a main PCB of a product.
