Patent number: 9105995Abstract: A terminal fitting (10) includes a tubular connecting portion (11) and a resilient contact (14) in the form of a plate that is deflectably arranged in the connecting portion (11) and that resiliently contacts a male tab (90) inserted into the connecting portion (11). A contact (35) is provided in a range from a contact start position (37) with the male tab (90) to a contact end position (38) inside the resilient contact (14) in a plate width direction. Curved portions (31) recessed toward a center in the plate width direction are provided on outer edges of the resilient contact (14) in the plate width direction. Parts of the curved portions (31) most recessed toward the center in the plate width direction are arranged to face the contact start position (37) of the contact (35) in the plate width direction.Type: GrantFiled: March 21, 2014Date of Patent: August 11, 2015Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Takeshi Tsuji, Norihiko Tanigawa, Yutaka Noro, Shohei Mitsui

Patent number: 9022797Abstract: A detector (70) movable from an initial position to a detection position is mounted on a housing main body (11). The detector (70) includes a resilient arm (72) resiliently deformable in a height direction. The resilient arm (72) contacts a lock arm (12) from behind before the housing main body (11) is connected to a mating housing (50) to prevent a forward movement at an initial position. When the housing main body (11) is properly connected to the mating housing (50), the detector (70) reaches a detection position where the resilient arm (72) enters a deformation space (25) by being pushed forward from the initial position. At the initial position, the resilient arm (72) applies a pre-load to the lock arm (12) in the height direction.Type: GrantFiled: February 7, 2013Date of Patent: May 5, 2015Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Akihiro Kon, Yutaka Noro

Patent number: 8926356Abstract: A protection wall (13) stands up from a rear end part of a housing main body (11) and restricts an operation of a disengaging portion (28) of a lock arm (12) by covering the disengaging portion (28). A detector (70) is made movable to a detection position by being pushed forward when the housing main body (11) is properly connected to a mating housing (50). Further, the detector (70) includes a rear portion (73) located behind the lock arm (12) and to be pushed when the detector (70) is moved to the detection position. A disengagement window (74) used to operate the disengaging portion (28) is formed on a position of the rear portion (73) behind the disengaging portion (28).Type: GrantFiled: February 7, 2013Date of Patent: January 6, 2015Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Akihiro Kon, Yutaka Noro
