Patent number: 10587085Abstract: Looseness of a rotary connector and lifting of the rotary connector which occurs depending on a harness wiring state are prevented, to reduce inconvenience such as generation of an abnormal sound due to the rotary connector contacting a steering wheel. In a fixing structure of a rotary connector, which includes a projecting piece 15 to fix the rotary connector to a combination switch and a locked portion 22a to be locked by the projecting piece 15 and in which a laterally protruding locking claw 31 is formed in a tip portion of the projecting piece 15, the locking claw 31 of the projecting piece 15 is integrally provided with a flexible urging portion 15a that displaces and urges the locking claw 31 in a locking direction. A contact surface 32 is formed on the locking claw 31, the contact surface 32 obliquely coming into contact with a locking side corner 23 of the locked portion 22a from the opposing side.Type: GrantFiled: April 28, 2017Date of Patent: March 10, 2020Assignees: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEMS INC., TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Shuji Hirai, Kazutaka Kamiya, Toshihiko Kosugi, Shigeo Shigeyama, Nobuyuki Ishigure, Yoshio Chiba, Kunihiko Ikegame, Hideki Matsumura, Tadashi Usuya

Patent number: 10439348Abstract: A rotator, which is configured by an annular top plate and a cylindrically shaped inner peripheral portion, and a stator, which is configured by assembling an annular stator main body and a cylindrically shaped sub stator, are assembled to be relatively rotatable in both a clockwise direction and a counterclockwise direction. An SRC that houses a flat cable being wound inside of a housing space formed therein is provided with a stator locking portion that enables a frame-shaped locking portion that extends from the stator main body to lock with a protruding locking portion that is formed on the sub stator; and a recess-protrusion fitting portion that suppresses the entry of foreign matter into the housing space. The recess-protrusion fitting portion is disposed on an opposing portion that corresponds to the stator locking portion.Type: GrantFiled: March 29, 2017Date of Patent: October 8, 2019Assignees: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEMS INC.Inventors: Shuji Hirai, Kazutaka Kamiya

Publication number: 20190089109Abstract: Aspects of the present invention relate to providing a rotary connector device capable of suppressing the entry of foreign matter into a housing space through a portion corresponding to a locking unit in an opposing portion between a stationary side ring plate and an outer peripheral cylindrical portion. A rotator (10), which is configured by an annular top plate (11) and a cylindrically shaped inner peripheral portion (12), and a stator (20), which is configured by assembling an annular stator main body (21) and a cylindrically shaped sub stator (22), are assembled to be relatively rotatable in both a clockwise direction and a counterclockwise direction.Type: ApplicationFiled: March 29, 2017Publication date: March 21, 2019Applicants: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEM INC.Inventors: Shuji HIRAI, Kazutaka KAMIYA

Patent number: 8808016Abstract: A rotatable connector device includes a steering roll connector that accommodates a flat cable in an accommodation space in the state where the flat cable can be wound and unwound. Also, a plurality of rotatable rollers are located on a top surface of a retainer concentrically with the retainer at an equal interval in a circumferential direction of the retainer. A regulation section on which a reversed part is allowed to be pressed is provided on the top surface of the retainer at a position away from one of the plurality of rotatable rollers, namely, a rotatable roller, on the side of a part of the rotatable roller along which the reversed part can be wound. The regulation section is away from the part of the rotatable roller by a gap which allows the reversed part to contact or detached from the rotatable roller.Type: GrantFiled: November 12, 2012Date of Patent: August 19, 2014Assignees: Furukawa Electric Co., Ltd., Furukawa Automotive Systems Inc.Inventors: Ryoichi Adachi, Kazutaka Kamiya

Patent number: 8758024Abstract: A rotary connector device includes a stator and a rotator which rotates with respect to the stator concentrically with a steering; an accommodating space having a ring shape in a plan view, which is formed inside the stator and the rotator, and which accommodates a cable for electrically connecting the rotator and the stator in a wound state; and a retainer which is located on a bottom surface of the accommodating space so as to be able to guide the cable to rotate concentrically circle with the steering. The rotator includes an inner peripheral tube portion which forms an inner peripheral surface of the accommodating space. A rotator side abutting portion which abuts an upper surface inner peripheral portion of the retainer in a slidable manner is formed on a lower portion of the inner peripheral tube portion.Type: GrantFiled: October 1, 2012Date of Patent: June 24, 2014Assignees: Furukawa Electric Co., Ltd., Furukawa Automotive Systems Inc.Inventors: Ryoichi Adachi, Kazutaka Kamiya

Patent number: 8529272Abstract: A steering roll connector includes a rotator, a sleeve, and a fixed casing. The rotator includes a claw and an inner cylindrical part, and is mounted to a steering shaft such that the rotator is rotated integrally with the steering shaft inserted in the inner cylindrical part. The sleeve includes a projection connectable with the claw, and is mounted to the rotator such that the sleeve is rotated integrally with the rotator. The fixed casing includes an outer cylindrical part, and is mounted such that the fixed casing does not follow rotation of the steering shaft inserted in the outer cylindrical part and such that the fixed casing is in contact with the sleeve. A combination of materials of the claw and the projection is such that occurrence of a squeak caused when the claw and the projection are rubbed against each other is suppressed.Type: GrantFiled: September 27, 2011Date of Patent: September 10, 2013Assignee: Furukawa Electric Co., LtdInventor: Kazutaka Kamiya
