Patent number: 6255590Abstract: A method of connecting a lead wire to a shield of a shielded cable. The method contains the steps of placing a lead wire on a shielded cable, and then subjecting the lead wire and the shielded cable to ultrasonic welding such that a conductor of the lead wire is joined to a shield of the shielded cable. The conductor of the lead wire is easily and reliably connected to the shield of the shielded cable, such as a shielding braid.Type: GrantFiled: April 20, 1999Date of Patent: July 3, 2001Assignee: Yazaki CorporationInventor: Kei Sato

Patent number: 6246001Abstract: Drain twisted wires of a plurality of shielded cables are connected with a ground wire without using a joint connector. In a grounding construction for grounding metal fiber braided wires of a plurality of shielded cables by connecting drain twisted wires 10a to 10f made of the metal fiber braided wires with each other and with a ground wire 11, sheaths of the plurality of shielded cables are stripped at positions corresponding to a sheath stripping position for the longest drain twisted wire. The drain twisted wires are bundled with the ground wire by a tape 12 from the sheath stripping positions P1. Resistance welding then is applied to ends of the twisted wires exposed from the leading end of the tape and to a core exposed from one end of the ground wire. The other end of the ground wire then is grounded.Type: GrantFiled: March 15, 2000Date of Patent: June 12, 2001Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Eiichi Fukui

Patent number: 6218619Abstract: A connecting structure for a shielded wire, including a shielded wire having a core made of a conductor, a core cover for covering the core, a braid provided around the core cover for shielding, and an insulating outer cover provided around the braid for covering the core, core cover and braid; and a shield terminal having a lead wire attached at an end to a terminal metal and conductively connected at a portion between the attached end and an unattached end to the braid of the shielded wire. This structure is formed by placing the portion of the lead wire of the shield terminal on the insulating outer cover of the shielded wire, placing a resin chip on the portion of the lead wire of the shield terminal, and applying an ultrasonic vibration so as to melt and disperse the insulating outer covers of the shielded wire and the lead wire, thereby forming a shielded conductive portion in which the shield terminal and braid are conductively in contact with each other.Type: GrantFiled: August 27, 1998Date of Patent: April 17, 2001Assignee: Yazaki CorporationInventors: Nobuyuki Asakura, Tetsuro Ide, Yasumichi Kuwayama

Patent number: 6184471Abstract: A shielded cable includes core wires, an inner insulating cover for covering the core wires, a braided wire on an outer periphery of the inner insulating cover, and an outer insulating cover on an outer periphery of the braided wire. A shielded terminal has an insertion connecting portion coated with low-melting point joining material. The insertion connecting portion of the shielded terminal is inserted into the inside of the shielded cable from outside of the outer insulating cover such that the low-melting point joining material opposes the braided wire. With this condition, the shielded cable is subjected to ultrasonic vibration through a plurality of small protrusions of an ultrasonic horn over the outer insulating cover. As a result, the low-melting point joining material is melted so as to conductively connect the insertion connecting portion and braided wire to each other.Type: GrantFiled: October 2, 1998Date of Patent: February 6, 2001Assignee: Yazaki CorporationInventors: Nobuyuki Asakura, Yasumichi Kuwayama, Tetsuro Ide
