UNIT LOCKING APPARATUS OF MOTOR CONTROL BOARD

摘要

PURPOSE: A unit locking apparatus of a motor control board is provided to prevent the fault operation of an equipment by maintaining positions of plural units inserted into the motor control board upon being applied an external impact. CONSTITUTION: A lock frame(400) is mounted on a case(3) of a unit. A rotor(401) is coupled to the lock frame(400) so as to be capable of rotating and provided with a male screw along a shaft direction on a circumference of the rotor(401). A lock lever(402) is inserted into the male screw of the rotor(401) to be screw-coupled. A coil spring(404) is fixed on one of the lock lever(402) and the lock frame(400) and adds an elastic force to the lock lever(402) being inserted into the circumference of the rotor(401). An L-shape lock recess(403) is formed through a control board frame(1) and a case(3) of a unit so that the lock lever(402) is guided.
