Patent number: 8241076Abstract: 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). With this arrangement, the tab (60) may be inserted at low frictional force but at complete insertion is held tightly be increased frictional force.Type: GrantFiled: October 4, 2010Date of Patent: August 14, 2012Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Motoki Kubota
