Patent number: 10014598Abstract: A terminal fitting (F) includes a pressure receiving portion (20) formed by causing a part of a first top plate (13) constituting a rectangular tubular body (10) to project toward a resilient contact piece (18), a locking projection (15) flush with the first top plate (13) and projecting from an extending end edge (13E) of the top plate (13) extending in a front-rear direction and locked to a right side plate (12R), and a right side edge (22R) constituting an outer peripheral edge part of the pressure receiving portion (20) and arranged along the extending end edge (13E) of the first top plate (13). A spacing in a width direction between the extending end edge (13E) of the first top plate (13) and the right side edge (22R) is smallest in an area corresponding to the locking projection (15).Type: GrantFiled: May 17, 2017Date of Patent: July 3, 2018Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Katsuya Uezono

Patent number: 9831586Abstract: A female terminal fitting (F) includes a rectangular tubular main body (10). The main body (10) has a rear base plate (14). Left and right side plates (15) are connected at substantially right angles to opposite left and right sides of the rear base plate (14). A main spring piece (20) is accommodated in the main body (10) and is configured to resiliently contact a tab (T) of a mating terminal (M) inserted into the main body (10). An auxiliary spring piece (23) is cantilevered from the rear base plate (14), is accommodated in the main body (10) and is configured to apply a resilient pressing force toward the tab (T) to the main spring piece (20). A reinforcing portion (28) is formed by striking a range from a base end part (23R) of the auxiliary spring piece 23 to the rear base plate (14).Type: GrantFiled: August 3, 2016Date of Patent: November 28, 2017Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Katsuya Uezono

Patent number: 9812806Abstract: A terminal fitting includes a wire connecting portion (11) to be connected to an end part of a wire. A terminal body (12) is provided in front of the wire connecting portion (11) and has a square cross-section. A projection (30) projects in a direction intersecting with a front-back direction from the terminal body (12). The projection (30) includes a standing wall portion (35) standing along a side surface of the terminal body (12) from a corner part of the terminal body (12), a front surface of the projection (30) is inclined to gradually reduce a projecting dimension toward front and a rear surface of the projection (30) is open in the front-back direction.Type: GrantFiled: November 21, 2016Date of Patent: November 7, 2017Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Katsuya Uezono

Patent number: 8523594Abstract: A housing (10) is formed with jig insertion holes (20) penetrating through an outer wall (19) located at a side of deformation spaces (17) opposite to locking lances (14). Deformation restrictions (42) of a front retainer (40) are formed with guides (49) that are cut out to allow an unlocking jig inserted through the jig insertion hole (20) to reach the locking lance (14) when the front retainer (40) is at a retracted position and to position the unlocking jig in a width direction crossing both a resiliently deforming direction of the locking lances (14) and an inserting direction of terminal fittings (30) into cavities (13).Type: GrantFiled: July 12, 2011Date of Patent: September 3, 2013Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Kazuaki Takeda, Katsuya Uezono, Takumi Hiraishi

Patent number: 8241075Abstract: A rectangular tubular terminal connecting portion (11) includes two side plates (17) standing up from opposite sides of a base plate (15) via curved portions (16). A resilient contact piece (20) includes a substantially arcuate turned portion (21) extending forward from a front end (15F) of the base plate (15) and a main portion (22) extending back from an extending end of the turned portion (21). First slits (24) extend back from a front end (11F) of the terminal connecting portion (11) along lateral edges (21S) of the turned portion (21), second slits (25) extend from the rear ends of the first slits (24) along the front ends (15F, 16F) of the base plate (15) and the curved portions (16), and protecting plates (26) defined by the first and second slits (24, 25) are cantilevered toward the turned portion (21).Type: GrantFiled: July 18, 2011Date of Patent: August 14, 2012Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Ryotaro Ishikawa, Kazuaki Takeda, Katsuya Uezono
