Abstract
A lever type connector of the present invention aims to effect a turning operation of a lever by a smooth and slight actuating force without forming the lever into a large size. In the lever type connector, cam faces 16a and 16b in a cam groove 16 displace a cam follower boss 17 by turning a lever 14, thereby coupling and detaching connector housings 11, 12. A shape of the cam faces 16a and 16b which contact with the cam follower boss upon coupling and detaching is formed in accordance with coupling and detaching resistances of a set of terminals. The cam groove 16 may be discontinuously formed by inserting and extracting resistances of the terminals so that a curved line is formed by combining two circular arcs through a point of inflection.
