Patent number: 10559908Abstract: A terminal fitting (80) includes a projection (92) on an outer surface of a body (81). A housing (10) includes a cavity (11) into which the terminal fitting (80) is to be inserted, a guiding groove (23) into which the projection (92) enters, and an inverted insertion guiding groove (28) into which the projection (92) enters when the body (81) is in an inverted insertion posture. The housing (10) includes an inverted insertion guiding slope (32) formed on a groove surface of the inverted insertion guiding groove (28), inclined in a direction intersecting an inserting direction of the body portion (81) to face the projection (92) and configured such that the projection (92) slides on the inverted insertion guiding slope (32).Type: GrantFiled: February 12, 2019Date of Patent: February 11, 2020Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Kazumi Oka

Patent number: 9356375Abstract: A male terminal fitting includes a tubular main body (10) and a plate-like tab (40) projecting forward from the main body (10). A first support (51) and a second support (52) are provided respectively on a surface side facing in a direction of action of the external force (P1, P2) and a surface side opposite to the former surface side at a front end part of the main body (10) connected to the tab (40). The first and second supports (51, 52) serve as starting points of bending when an excessive external force (P1, P2) acts on the tab (40) in a direction intersecting with a projecting direction of the tab (40) and are displaced from each other in a front-back direction.Type: GrantFiled: March 4, 2015Date of Patent: May 31, 2016Assignee: SUMITOMO WIRING SYSTEMS, LTD.Inventor: Kazumi Oka
