Abstract
Abstract A connector including a connector body, a movable plate mounted on the connector body, an operating lever, a contacting state and a contact-released state being produced by a lateral movement of the movable plate, the connector comprising an upper part operating member disposed above the operating lever for movement upward and downward, and a pressure bearing portion formed on one end portion of the operating lever and adapted to carry the upper part operating member, pushing down of the upper part operating member causing the pressure bearing portion to be pushed down to move the movable plate in a lateral direction.

A connector for mounting an electric element having depending terminals thereon and removing it from a circuit means, comprising: a connector body having a plurality of terminal receiving apertures therethrough each having a contact means therein with a contact part movable from a normally closed position where it contacts a terminal inserted into the aperture to an open position to permit no-load insertion and removal of the terminal; a movable plate mounted on said connector body for reciprocal movement along said body in a direction between ends of said body and transverse to said apertures and engaged with the contact elements so that, when the plate is moved in one direction along said body, the contact elements are moved to the open position; a pair of operating levers each having a lever arm on opposite sides of said connector body with each lever arm connected between said connector body and said movable plate and having a free end movable in a slightly curved path in the direction of the terminal receiving apertures, one operating lever having the free ends of said lever arms thereof at one end of said connector body, and the other operating lever having the free ends of said lever arms thereof at the other end of said connector body, for pivoting said levers to move said movable plate in said one direction; each lever arm having a zig-zag shape in the longitudinal direction with adjacent inner and outer lever arm portions defining a pair of guide spaces therebetween on each side of said connector body; and an upper part operating member having depending guide members extending through said guide spaces for being slidably mounted on said connector body for straight linear movement at a fixed position relative to said connector body and in the direction of said terminal receiving apertures and supported on said free end of said operating levers, whereby said upper part operating member is movable only in said fixed position and only in a straight line for operating said operating levers by moving said free ends in a curved line.
