Patent number: 9871311Abstract: A contact connection structure includes: a first contact portion including an indent portion spherically protruding, the first contact portion including a plating layer formed on a surface of the first contact portion; and a second contact portion including a plating layer formed on a surface of the second contact portion. The indent portion of the first contact portion is slidable on a contact surface of the second contact portion. The indent portion of the first contact portion at a terminal insertion completed position is in contact with the second contact portion. The contact surface of the second contact portion includes an oxide-film shaving portion having an annular arc portion curved along a circumference portion of the indent portion.Type: GrantFiled: October 11, 2016Date of Patent: January 16, 2018Assignee: YAZAKI CORPORATIONInventors: Masayuki Fukui, Yoshitaka Ito, Takaya Kondou, Takahiro Matsuo, Kenzo Tanaka, Takahiro Yudate, Masanori Onuma

Patent number: 9099792Abstract: A crimping terminal includes a conductor crimping portion which is connected to an electric cable so as to crimp the electric cable. The conductor crimping portion includes a bottom plate on which a conductor is placed and a pair of conductor crimping tabs which is provided on both sides of the bottom plate. The conductor crimping portion includes serrations that are formed at least a part of the inner surface thereof and retains the conductor of the electric cable inside the conductor crimping portion and at least one bead that protrudes from the inner surface.Type: GrantFiled: September 5, 2013Date of Patent: August 4, 2015Assignee: Yazaki CorporationInventors: Takaya Kondou, Masanori Onuma, Yoshitaka Ito

Patent number: 9099794Abstract: Concave serrations are provided in an inner surface of a conductor crimping portion of a crimp terminal. A number of circular concave portions are provided in the inner surface of the conductor crimping portion as the concave serrations so as to be scattered in a state of being spaced aside from one another. A diameter of an inner bottom surface of each circular concave portion is set within a range of 0.15 (an error range is ±0.04) mm to 0.8 (the error range is ±0.04) mm. A serration angle between an extension surface of the inner bottom surface and an inner side surface of each circular concave portion is set within a range of 60 to 90 degrees. A shortest distance of a flat surface portion between peripheries of mutually adjacent circular concave portions is set to be 0.17 (the error range is ±0.09) mm.Type: GrantFiled: April 2, 2014Date of Patent: August 4, 2015Assignee: YAZAKI CORPORATIONInventors: Yoshitaka Ito, Takaya Kondou, Masanori Onuma
