STRUCTURE FOR JOINING VOICE COIL MOTOR OF HDD

摘要

PURPOSE: A structure for joining a voice coil motor of an HDD(Hard Disk Drive) is provided to join a lower and an upper yoke of the voice coil motor on a base plate stably and easily. CONSTITUTION: A count sink(157) is formed on the lower yoke(151). Fixing to a flat head screw hole(112) formed to the base plate(110) by being inserted into the count sink, a flat head screw(158) fixes the lower yoke to the base plate. A boss inserting hole(156) is formed on both lengthwise ends of the upper and the lower yoke(152). A boss(120) projected/formed on the base plate prevents horizontal movement of the upper and the lower yoke by being inserted into the boss inserting hole. Joined to a screw hole(114) formed to the boss by being inserted into the boss inserting hole, a screw(159) fixes the upper yoke to the lower yoke.
