Patent number: 9755325Abstract: A conductor wire crimping portion (7) has depressions (13a, 13b, 13c) that are disposed at prescribed intervals in the axial direction and that are linear locking portions. The depressions (13a, 13b, 13c) are continuously depressed grooves on the inner surface of a crimping portion (5). On an upper die (30a), at a portion corresponding to the conductor wire crimping portion (7), a straight portion is formed, and in the front-back direction thereof, tapered portions are formed. More specifically, the upper die (30a) is formed to have an inverted trapezoid shape, a middle portion of which protrudes in the crimping direction. Consequently, at each boundary between the straight portion and the tapered portion, a die angled portion (32) is formed. At an area corresponding to the straight portion of the upper die (30a), the depression (13a) is provided, and at an area corresponding to the die angled section (32), the depression (13b) is provided.Type: GrantFiled: April 1, 2016Date of Patent: September 5, 2017Assignees: FURUKAWA ELECTRIC CO., LTD., FURUKAWA AUTOMOTIVE SYSTEMS INC.Inventors: Takashi Tonoike, Yukihiro Kawamura, Yasushi Kihara, Hiroshi Orito, Kyutaro Abe, Tsuneo Aoi, Koji Yamanaka, Tomoki Kawamura

Patent number: 7980739Abstract: An in-vehicle illuminating device 1 capable of efficiently guiding luminous flux emitted from a luminous source to a light guiding body. The in-vehicle illuminating device 1 is provided with a rod-shaped light guiding body 13 which reflects, on its inner surface, light rays incident from an optical incidence plane 16 provided at an end 13a to guide the light rays to the other end longitudinally provided, a lamp 19 which emits light to a direction orthogonal to the longitudinal direction of the rod-shaped light guiding body 13 and is arranged in the vicinity of the optical incidence plane 16, and an light introducing body 20 for introducing the luminous flux emitted from the lamp 19 to the optical incidence plane 16. The light introducing body 20 allows the optical incidence plane 16 to be set within a range of the luminous flux emitted from the lamp 19.Type: GrantFiled: March 12, 2009Date of Patent: July 19, 2011Assignee: Honda Access CorporationInventors: Shiro Iwai, Tomoki Kawamura, Hiroto Murabayashi
