Patent number: 8662910Abstract: A vehicle-side connector (10) includes a mounting plate (40) fixed to an outer panel (P) of a vehicle. An inner tube (20) penetrates the mounting plate (40). An outer tube (30) surrounds the inner tube (20) and projects from the mounting plate (40) toward the inside of the vehicle. A rubber plug (80) forms a sealed space (33) in the outer tube (30) between wires (W) pulled into the vehicle. A plug presser (90) is mounted in the opening of the outer tube (30) to retain the rubber plug (80). An inclined surface (84) is provided in the sealed space (33) and inclines down toward the outside of the vehicle. A drain channel (32) and a drain port (42) penetrate though the mounting plate (40) and drain water from the drain channel (32) to the outside of the vehicle.Type: GrantFiled: May 9, 2012Date of Patent: March 4, 2014Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Toshifumi Ichio, Akinori Takada

Patent number: 8342856Abstract: A charging connector (10) has terminal fittings (20) including female-side main portions (21) connectable to a vehicle-side terminal (60) and having a wire (W) connected to the rear end of the main portion (21). Terminal accommodating portions (15) are formed internally with cavities (17) for accommodating the terminal fittings (20). Seals (30) are sandwiched between facing inner walls of the cavities (17) and the main portions (21). Wire accommodating portions (11, 12) are behind the terminal accommodating portions (15) for accommodating the wires (W) in a state where reaction forces push the terminal fittings (20) forward. Each terminal fitting (20) is biased constantly forward by the reaction force of the wire W against a frictional force with the seal ring (30), thereby being arranged at a frontmost position where the front end of the main portion (21) and a front wall (17A) of the cavity (17) are in contact.Type: GrantFiled: February 14, 2011Date of Patent: January 1, 2013Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Akinori Takada, Toshifumi Ichio

Patent number: 8251742Abstract: A charging connector (10) is provided for connection to a vehicle-side connector (50) in a vehicle. The charging connector (10) has terminal fittings (20) to be electrically conductively connected to vehicle-side terminals (60) in the vehicle-side connector (50), and terminal accommodating portions (15) internally formed with cavities (17) for accommodating the terminal fittings (20). A front wall of each cavity (17) includes a resilient member (30) that allows the insertion of the vehicle-side terminal (60) into the cavity (17) while being held in close contact with the vehicle-side terminal (60) over the entire circumference.Type: GrantFiled: March 8, 2011Date of Patent: August 28, 2012Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Akinori Takada

Patent number: 8152550Abstract: A vehicle charging connector is configured to be coupled to a vehicle-side connector to charge a vehicle battery via the vehicle-side connector. The vehicle charging connector includes a housing, a coupling portion provided on a housing, and a lever. The lever has a lever bar accommodated in the housing, a lock portion provided on one end of the lever bar and configured to engage with a lock receiving portion of the vehicle-side connector to maintain the coupling portion and the vehicle-side connector in a coupled condition, and an unlock operation portion provided on the other end of the lever bar and operable to release an engagement between the lock portion and the lock receiving portion. An upper surface of the lever bar includes a water guide adjacent to the lock portion. The water guide includes a slope surface having a downward inclination.Type: GrantFiled: July 11, 2011Date of Patent: April 10, 2012Assignees: Sumitomo Wiring Systems, Ltd., Toyoto Jidosha Kabushiki KaishaInventors: Toshifumi Ichio, Akinori Takada, Shuichi Nagata
