  • Patent number: 9601855
    Abstract: A female terminal (40) to be connected to a male terminal (80) includes a tubular portion (41) configured by a plurality of peripheral walls. Resilient pieces (46, 47) extend in a front-back direction while facing the peripheral walls in the tubular portion (41). Excessive deflection preventing portions (90, 91) are provided on the peripheral walls, including a front abutting portion (92) and a rear abutting portion (93) arranged behind the front abutting portion (92), and configured to prevent the resilient pieces (46, 47) from being deflected excessively by contacting the resilient pieces (46, 47) at both the front and rear abutting portions (92, 93).
