Female terminal fitting

摘要

A female terminal fitting (10) is provided with a tubular main body portion (20) into which a mating male tab (90) is to be inserted, and a resilient contact piece (21) deflectably arranged in the main body portion (20). The resilient contact piece (21) is resiliently deformed toward a base wall (22) of the main body portion (20) to resiliently come into contact with the male tab (90) when the male tab (90) is inserted into the main body portion (20). An excessive deflection regulating piece (33) for regulating excessive deflection of the resilient contact piece (21) by coming into contact with the base wall (22) of the main body portion (20) is integrally provided to the resilient contact piece (21).

1. A female terminal fitting with a tubular main body portion into which a mating male tab is to be inserted, and a resilient contact piece deflectably arranged in the main body portion, the resilient contact piece being resiliently deformed toward a base wall of the main body portion to resiliently come into contact with the male tab when the male tab is inserted into the main body portion, wherein:
an excessive deflection regulating piece for regulating excessive deflection of the resilient contact piece by coming into contact with the base wall of the main body portion is integrally provided to the resilient contact piece; and an auxiliary spring piece cantilevered in a direction opposite to an inserting direction of female tab is deflectably arranged in the main body portion, a spring force of the resilient contact piece is assisted by the contact of a free end part of the auxiliary spring piece with the resilient contact piece in a deflecting direction thereof, and the excessive deflection regulating pieces are formed by bending parts of the resilient contact piece protruding outwardly in a width direction toward the base wall of the main body portion and arranged to be proximate to opposite widthwise side edges of the free end part of the auxiliary spring piece and face and cover the opposite widthwise side edges.
