Patent number: 8356999Abstract: A lever-type connector has a female housing (30) that can be connected with and separated from a male housing (10) as a lever (50) is rotated. The lever-type connector has first and second cam pins (32, 33). A first gear (51) is rotated as the lever (50) is rotated and has a first cam groove (54) engageable with the first cam pin (32). A second gear (61) is rotated as the first gear (51) is rotated and has a second cam groove (64) engageable with the second cam pin (33). A width of the first cam groove (54) in a direction orthogonal to a moving direction of the first cam pin (32) exceeds the outer diameter of the first cam pin (32) in conformity with a backlash (S) between the two gears (51, 61). A width of the second cam groove (64) in a direction orthogonal to a moving direction of the second cam pin (33) is substantially equal to the outer diameter of the second cam pin (33).Type: GrantFiled: February 17, 2010Date of Patent: January 22, 2013Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Yuujirou Imai

Patent number: 7645172Abstract: A connector has terminal fittings (20) with a touching section (41) to be held in contact with a mating terminal (30) and a housing (10) formed with press-in holes (14, 14A), into which the terminal fittings (20) are pressed. The terminal fittings (20) are pressingly held in the housing (10) after the touching sections (41) pass through the press-in holes (14, 14A). A part of the inner surface of each press-in hole (14, 14A) of the housing (10) corresponding to a passage area of the touching section (41) is shaped to be gradually distanced from the passage area towards an apex (62, 62A) at a widthwise middle part (65) of the passage area. Accordingly, mutual abrasion of the touching section (41) and the inner surface of the press-in hole (14, 14A) can be avoided when the touching section (41) passes through the press-in hole (14, 14A).Type: GrantFiled: January 23, 2008Date of Patent: January 12, 2010Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Yuujirou Imai

Patent number: 7384286Abstract: A connector has female and male housings (10, 60). A cam pin (63) projects from the male housing (60), and a jaw (65) bulges out at the end of the cam pin (63). A lever (30) is mounted to the female housing (10), and has a cam groove (33) for engaging the cam pin (63). A step (38, 39) in the cam groove (33) defines an accommodating portion (42) for the jaw (65). The depth of the accommodation portion (42) is larger near the entrance of the cam groove (33) so that the jaw (65) initially is accommodated loosely. However the depth of the accommodating portion (42) is smaller towards the back of the cam groove (33) to prevent loose movements.Type: GrantFiled: March 2, 2007Date of Patent: June 10, 2008Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yuujirou Imai, Tetsuya Shinozaki
