Abstract

A female terminal fitting (10) has a tubular main portion (11) with first and second opposed resilient pieces (21, 24) formed therein. The second resilient piece (24) has an extending piece (25), a support (26) and a pressing piece (27). The support (26) contacts the inner surface of the main portion (11) and the pressing piece (27) extends from the support (26) to hold the first resilient piece (21) in a pre-loaded state. A tab (60) is inserted between the extending piece (25) and the first resilient piece (21) to incline the pressing piece (27) about the support (26) and to release the pre-loaded state. The extending piece (25) resiliently deforms about the support (26) and toward the tab (60) as the pressing piece (27) is inclined. Thus, the tab (60) is held resiliently between the extending piece (25) and the first resilient piece (21).

Dependent claims

A female terminal fitting, comprising:

a main portion (11) with an open front end and opposite first and second walls (13, 18) extending rearward from the front end;
a resiliently deformable first resilient piece (21) extending rearward from the open front end of the main portion (11) and disposed between the first and second walls (13, 18);
and
a resiliently deformable second resilient piece (24) formed in the main portion (11) between the first resilient piece (21) and the second wall (18), the second resilient piece (24) including an extending piece (25), a support (26) and a pressing piece (27), the extending piece (25) extending rearward from a position in proximity to front end of the main portion (11), the support (26) being at a rear end of the extending piece (25) and being in contact with an inner surface of the second wall (18), the pressing piece (27) extending from the support (26) to the first resilient piece (21) and holding the first resilient piece (21) in a pre-loaded state.
