ABSTRACT:
A connector connectable and disconnectable without requiring any force comprises a pivotal lever, a slide plate linearly movable in its longitudinal directions by the operation of the lever and adapted be raised and lowered in response to the linear movements, and an ON-OFF plate adapted to rise and lower in response to the rising and lowering movements of the slide plate for opening at least one pair of contacts by inserting the ON-OFF plate between the contacts in the rising movement of the ON-OFF plate and closing the pair of contacts by removing the ON-OFF plate from between the contacts in the lowering movement of the ON-OFF plate. According to the invention, the lever is made detachable from the connector to avoid the need of bulky boxes for packaging due to its elongated lever and risk of damage to the lever subjected to excess forces.
