Abstract
Abstract Electrical connector (1) comprises a housing body (52) which has a plurality of contact terminals (2) extending therein. Each terminal (2) has one contact leg (6 ) which extends from a shank portion (24) to a mating surface (78) of housing body (52). The use of only one contact leg (6) for each terminal (2) allows the mating zone of the connector (1) to have increased tolerances, thereby allowing for a slightly misaligned mating pin (80) to be inserted therein. Portions of inner ends (20) of the shank portions (24) are provided to cooperate with shoulders (70) of the housing body (52), thereby insuring that the terminals will have a positive stop means as the terminals are inserted into the housing body. The cooperation of inner ends (20) and shoulders (70) also insures that the terminals (2) will be prevented from movement when the connector housing is terminated to a ribbon cable (48).
