Patent number: 7175486Abstract: A terminal fitting (T) has a rectangular tube (10) with a bottom plate (12). A resilient contact (25) extends back into the tube (10) from an end of the bottom plate (12). A base portion (33) is formed at the front end of the bottom plate (12) and is made narrower than the bottom plate (12) by cutting away the left and right edges. A bulge (34) bulges out from a lateral edge of the base portion (33) and narrows an area of an opening between the base portion (33) and the right side plate (13R). Thus, external matter is less likely to intrude into the rectangular tube (10) through the opening even if the resilient contact (25) is narrow. Additionally, the base portion (33) is reinforced by the bulge (34). Thus, the base portion (33) is less likely to be deformed by external matter.Type: GrantFiled: February 1, 2006Date of Patent: February 13, 2007Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yutaka Noro, Ryotaro Ishikawa, Hajime Kawase, Keiichi Nakamura, Yutaka Kobayashi

Patent number: 7147522Abstract: A stabilizer (30) is divided into a front stabilizer (31A) and a rear stabilizer (31B) with a small clearance therebetween. The front and rear stabilizers (31A, 31B) are formed from a left side plate (25) and a bottom plate (25) of a main portion (21) by cutting and bending while leaving holes (32A, 32B). The side hole (32A) is relatively larger and exposes a free end (40A) of a resilient contact (40) to the outside. Thus, a rear inner plate (36) is arranged at an inner side of the side hole (32A) to close the side hole (32A). The plastic deformation of a side of the resilient contact (40) towards the free end (40A) is prevented by preventing the intrusion of a tab (51) of a male terminal fitting (50) or other external matters through the side hole (32A).Type: GrantFiled: February 1, 2006Date of Patent: December 12, 2006Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yutaka Kobayashi, Hajime Kawase, Yutaka Noro

Patent number: 7094101Abstract: A terminal fitting (T) has a rectangular tube (10). A resilient locking piece (25) is accommodated in a rectangular tube portion (10) and a locking hole (19) in the tube (10) exposes the resilient locking piece (25). A side plate (13R) of the rectangular tube (10) is provided with an intrusion restricting portion (21) near the resilient contact piece (25) and in an opening area of the locking hole (19). Thus, the intrusion of an external matter through the locking hole (19) can be restricted by the intrusion restricting portion (21), thereby preventing the interference of the external matter with the resilient contact piece (25).Type: GrantFiled: February 1, 2006Date of Patent: August 22, 2006Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yutaka Noro, Ryotaro Ishikawa, Hajime Kawase, Takahiro Yoneda, Ryo Sawada, Ken Yoshimura

Patent number: 7094115Abstract: A female terminal fitting (20) has an approximately tubular connection portion (22) with an open front end for receiving a tab (14) of a male terminal fitting (10). Concavities (30) extend longitudinally in the connection portion (22) at positions opposed to side surfaces of the tab (14). The concavities (30) enable the outside width (W) of the connection portion (22) to be small while securing a large clearance (C) outward from the side surfaces of the tab (14). The concavities (30) do not significantly decrease the strength of the entire connection portion (22). Additionally, the large clearance (C) avoids the need for highly accurate manufacturing.Type: GrantFiled: July 5, 2005Date of Patent: August 22, 2006Inventors: Yutaka Noro, Ryotaro Ishikawa, Hajime Kawase
