Patent number: 8215987Abstract: A retainer (40), a rubber plug (60) and a rubber plug pressing member (70) are mounted in a housing (10). The retainer (40) is movable between a partial locking position and a full locking position, and the rubber plug pressing member (70) is movable between an initial position and a pushed-in position. The rubber plug pressing member (70) is formed with arm portions (74) projecting therefrom. The retainer (40) is formed with unlock linking portions (46) for linking a movement of this retainer (40) from the full locking position to the partial locking position and a movement of the rubber plug pressing member (70) from the pushed-in position to the initial position with each other by coming into sliding contact with the arm portions (74).Type: GrantFiled: October 6, 2010Date of Patent: July 10, 2012Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Chikahiro Yoshioka, Tomohiko Kobayashi, Shinji Hirano, Masatoshi Itou

Patent number: 7997916Abstract: A rubber plug (40) is provided with a stable sealing property while reducing frictional resistance when the rubber plug (40) is inserted into a cavity. In a cross section including axis lines of the rubber plug (40), a cavity (11) and a wire (30), areas of outer lips (44A, 44B) not resiliently deformed radially outward of a virtual line (12L) corresponding to the inner circumferential surface of the cavity (11) are specified as outer virtual deforming portions (45A, 45B), areas of inner lips (46A, 46B and 46C) not resiliently deformed radially inward of a virtual line (31L) corresponding to the outer circumferential surface of the wire (30) are specified as inner virtual deforming portions (47A, 47B, and 47C) and at least parts of the inner virtual deforming portions (47A, 47B and 47C) correspond to only parts of the outer virtual deforming portions (45A, 45B).Type: GrantFiled: April 1, 2010Date of Patent: August 16, 2011Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Chikahiro Yoshioka, Yasuaki Nakayama

Patent number: 7448894Abstract: A object of the present invention is to enable a double-locking of female terminals without making a whole connector larger in size or complicating a structure thereof while maintaining fine waterproof function. A female connector C1 includes a female housing 12 for retaining a female terminal 10 and a seal member holder 16. The seal member holder 16 retains a seal member 14 having through holes 14a. When the seal member holder 16 is completely attached to the female housing 12, the seal member 14 comes in close contact with a front surface of the female housing 12. In this state, a male terminal 20 of a male connector C2 fits into the female terminal 10 so that a projecting portion 25 of the connector C1 comes in close contact with an inner surface of the through hole 14a to make terminals waterproof individually.Type: GrantFiled: November 16, 2005Date of Patent: November 11, 2008Assignees: Autonetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Takeshi Tsuji, Michiaki Okamoto, Hiroki Hirai, Chikahiro Yoshioka
