Patent number: 7087839Abstract: A slack-based method for determining fastener placement tolerances for a wire harness relative to a vehicle mounting point layout. The method uses a determination of maximum permissible slack between pairs of adjacent mounting points to calculate tolerances for each point-to-point segment of the wire harness. The determination of maximum permissible slack is made by inspection of the vehicle mounting point layout between each set of mounting points, and in particular is based on real-life slack-limiting factors found to exist between the mounting points. The point-to-point tolerances are easily summed to determine an overall harness length sufficient to create the desired slack and tolerances. The overall length can be optimized for the greatest number of fastener placement options with the least amount of excess harness.Type: GrantFiled: July 11, 2002Date of Patent: August 8, 2006Assignee: Yazaki North America, Inc.Inventor: Michael W.

Patent number: 6059617Abstract: A protective member (28) having a melting point lower than a cover (12) is provided on a distal end of a protrusion (22) of the cover (12). A terminal (13) and a covered electric wire (19) are housed in a groove portion (18) of a connector housing (11), and the protrusion (22) of the cover (12) is inserted into the groove portion (18), and thereafter, an ultrasonic vibration is applied to the covered electric wire (19) and the terminal (13) from the cover (12). A covering portion (27) of the covered electric wire (19) is melted and removed by the ultrasonic vibration. The protective member (28) absorbs a heat generated in the cover (12) by applying the ultrasonic vibration, and is preferentially melted. Therefore, the protrusion (22) is not deformed due to the heat, so that a contact area of a core wire (26) and the terminal (13) can be secured.Type: GrantFiled: June 17, 1998Date of Patent: May 9, 2000Assignee: Yazaki CorporationInventor: Akira Shinchi

Patent number: 6026567Abstract: A method of interconnecting a core, a stranded conductor such as a wire rope or cable and a component of a medical electrical lead provided with a internal lumen. At least one of the core and the internal lumen of the component is provided with a textured surface, such as threading. The conductor is located alongside said textured surface and the core is advanced into the lumen of said component, such that the textured surface engages the conductor and retains the conductor as the core is advanced into the lumen, and the conductor is compressed between the core and the inner lumen of the component.Type: GrantFiled: May 11, 1995Date of Patent: February 22, 2000Assignee: Medtronic, Inc.Inventors: John M. Swoyer, Diane M Radloff, Peter B. Mc Intyre, Timothy G. Laske

Patent number: 6004170Abstract: A covered wire connection structure is formed by the steps of: pinching a covered wire with a pair of resin chips; pressing and exciting a cover portion of the wire by ultrasonic vibration so as to conductively connect conductive portions of both the covered wires at the connection portion; and melting a pair of the resin chips so as to seal the connection portion. The resin chip comprises main melting portions for pinching the connection portion which are melted to a mating resin chip so as to seal the connection portion, and auxiliary melting portions which are formed of material compatible with the cover portion of the covered wire introduced from the main melting portions and pinch the cover portion such that they are melted to the mating resin chip. The auxiliary melting portions and cover portion of the covered wire are melted together and integrated so as to seal an introductive portion of the covered wire from the resin chips.Type: GrantFiled: October 23, 1997Date of Patent: December 21, 1999Assignee: Yazaki CorporationInventors: Tetsuo Kato, Nobuyuki Asakura, Akira Shinchi, Tetsuro Ide

Patent number: 5959252Abstract: Two covered wires conductively connected are overlapped with each other at connection portions S. The overlapped connection portions are pinched by a pair of resin chips. Cover portions are melted and the conductive wire portions of both the covered wires are conductively contacted with each other at the connection portions by pressing from outside of the resin chips. Then, the pair of the resin chips are melt-fixed to each other to seal the connection portions. The resin chips are provided with first melting portions which are melt-fixed to a mating chip in area including the connection area to seal the connection portions and second melting portions which are separated from the first melting portions and melt-fixed to the mating chip in area other than the connection portion. Thus, it is possible to achieve reduction of conducting resistance and improvement of mechanical strength.Type: GrantFiled: June 3, 1997Date of Patent: September 28, 1999Assignee: Yazaki CorporationInventors: Tetsuro Ide, Nobuyuki Asakura

Patent number: 5906044Abstract: The claimed invention provides an ultrasonic welding method, whereupon joint portions in which a copper foil portion and a twisted-wire electric cable are placed one upon the other in each groove of a resin casing, the grooves having a through-hole portion. In the through-hole portion, the copper foil portion and the twisted-wire electric cable are placed one upon the other. Welding is performed in a state in which the piled-up portion is sandwiched between a welding tip formed at an end of a welding head and an anvil. Thus, the joint portion between the copper foil portion and the twisted-wire electric cable invade and are invaded by a portion of the resin casing softened by welding heat. The joint portion is fastened not only by welding, but also by the solidified resin.Type: GrantFiled: December 4, 1996Date of Patent: May 25, 1999Assignees: Harness System Technologies Research, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Atsuhiko Fujii, Kazuhito Murakami

Patent number: 5898993Abstract: An object of the invention is to quickly supply inexpensive large current terminals without entailing complicated metal-working process and labor. Further, another object thereof is to provide methods of metal-working such terminals. A large current male terminal is constructed by forming a hollow cylindrical electric contact part on one end of a conductive pipe, a hollow cylindrical wire crimping part on the other end thereof, and a collar between the electric contact part and the wire crimping part. The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto.Type: GrantFiled: April 28, 1997Date of Patent: May 4, 1999Assignee: Yazaki CorporationInventors: Shigemitsu Inaba, Mitsuhiro Matsumoto, Satoki Masuda
