Patent number: 7121903Abstract: The terminal includes a front portion, a middle portion, and a rear portion. The rear portion is opened and has a pair of upright segments. The front portion is a shape of hollow cylinder and has bent tips. The middle portion is partly opened and an inner edge thereof has a collapsed or chamfered face. A step H is disposed between the rear portion and the front portion so that the middle portion is downwardly tapered to the rear portion. A through-hole is disposed at inner wall of the middle portion close to the rear portion for a part of the core wires, preferably edges of the covers also, to be visible through the through-hole.Type: GrantFiled: September 20, 2005Date of Patent: October 17, 2006Assignee: Yazaki CorporationInventors: Tadahisa Sakaguchi, Masanori Onuma, Nobuyuki Asakura

Patent number: 7077712Abstract: The jointing sleeve component includes a sleeve made of electrically conductive metal. A diameter of the sleeve is to be reduced by swaging on a condition that core wire ends of a plurality of coated electric wires are received in the sleeve. Each core wire end is obtained by removing an insulating coating from the coated electric wire. The jointing sleeve component electrically connects the core wire ends to each other. The sleeve is formed in a pipe-shape from a developed material, which is stamped out from a plate made of the electrically conductive metal to have a specific shape.Type: GrantFiled: July 6, 2005Date of Patent: July 18, 2006Assignee: Yazaki CorporationInventors: Tadahisa Sakaguchi, Masanori Onuma, Nobuyuki Asakura

Patent number: 7074077Abstract: A connection cap that includes a rear end wall positioned at a rear end of the connection cap for confining a sealing uncured resin, an opening positioned at a forward end of the connection cap for inserting a jointing portion of core wires of electrical cables, and a cylindrical wall extending from the opening to the rear end wall. The cylindrical wall has an inner surface formed with a plurality of ribs for positioning the jointing portion in the connection cap. The ribs are distributed in a circumferential direction to uniformly support the electrical cable. The uncured resin intrudes clearances each defined between adjacent two of the ribs. The inner surfaces of ribs define an inscribed circle having a diameter substantially the same as an outer diameter of a conductive sleeve for crimping the core wires. Advantageously, the ribs each have a forward end portion formed with a tapered surface gradually rising toward the rear end of connection cap.Type: GrantFiled: December 1, 2004Date of Patent: July 11, 2006Assignee: Yazaki CorporationInventors: Tadahisa Sakaguchi, Masanori Onuma
