Abstract

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 by 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.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 115 words
A lever type connector wherein a lever is rotatably connected to one of connector housings to be coupled to each other, a cam follower boss is provided on the other of said connector housings, said boss is adapted to engage with a grooved cam formed in said lever, and said connector housings are coupled to and detached from each other by turning said lever so that said cam follower boss is displaced along a cam face on said grooved cam; characterized in that a shape of said grooved cam on which said cam follower boss contacts upon coupling and detaching of said connector housings is formed by coupling and detaching resistances of said connector housings.
Claim 2
Dependent Claim 171 words
A lever type connector according to Claim 1 wherein one and the other of a pair of connector housings are provided with one and the other of sets of male terminals and female terminals to be coupled to each other, a lever is rotatably connected to one of said connector housings to be coupled to each other, a cam follower boss is provided on the other of said connector housings, said boss is adapted to engage with a grooved cam formed in said lever, said sets of terminals are inserted into and extracted from each other by turning said lever so that said cam follower boss is displaced along a cam face on said grooved cam, and more than two sets of terminals are provided which are different in timings of inserting and extracting of said terminals; characterized in that a shape of said grooved cam on which said cam follower boss contacts upon inserting and extracting of said terminals is discontinuously formed by inserting and extracting resistances of said terminals.
