Patent number: 9787012Abstract: It is aimed to provide a terminal fitting (1) in which thick plating films can be formed on necessary parts without requiring particularly complicated plating. The terminal fitting (10) includes a tubular connecting portion (11) into which a mating male terminal (60) is insertable. The connecting portion (11) includes a plurality of resilient pieces (14) circumferentially divided via expanding slots (13) extending from a tip. Thick film portions (22) with a thicker plating film than in other parts are provided on inner surfaces of the plurality of resilient pieces (14) and contact areas (17) capable of contacting the male terminal (60) are provided on these thick film portions (22). The thick film portions (22) and the contact areas (17) are arranged continuously in a circumferential direction except at the positions of the expanding slots (13) on an inner surface of the connecting portion (11) near a tip.Type: GrantFiled: September 8, 2014Date of Patent: October 10, 2017Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Daichi Kawaguchi, Shiro Nishida, Nobuyuki Akiba, Takuya Utsunomiya, Fumitaka Maekawa

The composite magnetic particle has a metallic magnetic particle and a coating layer coating the metallic magnetic particle and containing an oxide therein. The organic substance is formed by adding at least one of a thermoplastic resin and a higher fatty acid having an effect of increasing resistivity of the material, to a non-thermoplastic resin having an effect of improving durability such as material fatigue limit. The organic substance is contained in the soft magnetic material by not less than 0.001% by mass and not more than 0.2% by mass. The present invention provides a soft magnetic material having high magnetic property and mechanical strength and also having fatigue property and resistivity satisfying durability enough for use as a motor core or the like, and a method for manufacturing the same. Further, the invention provides a motor core and a transformer core made of the soft magnetic material.Type: ApplicationFiled: May 28, 2004Publication date: May 5, 2011Inventors: Haruhisa Toyoda, Daichi Kawaguchi, Shohzoh Tanaka, Kazuhiko Ueda
