Patent number: 7175489Abstract: Joint terminals (20c) and a housing (10) are united by a press-in operation instead of being united by insert molding. Thus, there is no likelihood that an injection pressure will deform the joint terminals (20c). The joint terminal (20c) has a coupling (21) bent so that upper and lower supports (26, 27) are formed at the opposite sides of an intermediate portion (28). A high dimensional precision can be obtained even when an automatic mounting machine is used for pressing the joint terminals (20c) into the housing (10).Type: GrantFiled: October 8, 2004Date of Patent: February 13, 2007Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Masayasu Fujii, Toshikazu Sakurai

Patent number: 7172471Abstract: The invention relates to an electrical high-current contact element essentially comprising a basic contact element made of metal exhibiting good conductivity and a steel spring, which is incorporated into a plug connector housing for the mounting of a high-current plug connector. The steel spring comprises two spring arms at a distance from one another, which are connected to one another by means of a U spring arm base. The contact arm is arranged in a manner reaching through the spring arm base between the spring arm and the spring arm. The high-current mating contact element is inserted into the mouthlike plug-in opening during the production of the plug connection, functional parts at plug connector housing and high-current mating plug connector opening the two spring arms and thus also the plug-in opening.Type: GrantFiled: September 23, 2005Date of Patent: February 6, 2007Assignee: Lear CorporationInventor: Hermann Bommersheim

Patent number: 7172472Abstract: A joint terminal (20c) has a coupling (41) that initially is substantially parallel with a carrier (51). The coupling (41) has an intermediate portion (45) joined to the carrier (51) by an extension (52) and is held substantially coplanar with the carrier (51). The coupling (41) is bent on opposite ends of the intermediate portion (45) while the intermediate support (45) and the carrier (51) are being held to define a first support (43) that support first tabs (42) and a second support (44) that supports second tabs (22).Type: GrantFiled: October 8, 2004Date of Patent: February 6, 2007Assignee: Sumitomo Wiring Systems, Ltd.Inventor: Masayasu Fujii

Patent number: 7131192Abstract: This invention is a method of manufacturing printed circuit boards using a contact block packaging to provide and support electrical contact blocks relative to a printed circuit board panel. The contact block packaging is situated adjacent to the printed circuit board panel, so that electrical contact blocks of the contact block packaging are aligned with circuit boards of the printed circuit board panel, but breakaway stems supporting the electrical contact blocks are offset from webbing of the printed circuit board panel. The electrical contact blocks are then soldered to the printed circuit boards. Thereafter, the breakaway stems of the contact block packaging and the webs of the printed circuit board panel are broken, so that the electronic contact blocks are decoupled from the rest of the contact block packaging and the printed circuit boards are decoupled from the rest of the printed circuit board panel.Type: GrantFiled: June 5, 2004Date of Patent: November 7, 2006Assignee: Motorola, Inc.Inventor: Robert Stanford

Patent number: 7118430Abstract: An electrical connector for use in forming a wire-wrapped welded terminal connection. The connector is formed by stamping and folding from a sheet of metal stock to include an integral sleeve element attached by a strap. During assembly of the connection prior to welding, the terminal is wrapped with wire as in the prior art and then the strap is folded to position the integral sleeve element correctly about the wrappings to form a weldable assembly functionally identical with the prior art sleeved assembly. Because the sleeve element is formed integrally with the connector and attached by a foldable strap, the element is automatically positioned correctly and is held in place by the strap during welding.Type: GrantFiled: March 31, 2005Date of Patent: October 10, 2006Assignee: Delphi Technologies, Inc.Inventors: James P. Henry, Daniel L. Varble

Patent number: 7090547Abstract: Even in the case of a bar-like small terminal connection, its strength is retained. In (a), a strip (21) made, for example, of a thin metal sheet having a thickness of 0.2 mm and a predetermined width is collapsed by rolling to a thickness of 0.16 mm as in (b). Subsequently, as in (c), the longitudinal opposite sides (22, 23) of the strip (21) are erected with respect to the base plate (24), then inwardly bent, as in (d), and folded onto the base (24), as in (e). Further, the folded opposite sides (22, 23) are erected together with the base plate (24) into a closely contacted state, whereupon as in (f), the folded body is mechanically compressed from all sides into a form having a 0.64-mm square cross section.Type: GrantFiled: July 10, 2003Date of Patent: August 15, 2006Assignee: Mitsubishi Cable Industries, Ltd.Inventors: Yukifumi Machida, Yoshikazu Tanaka, Hiroshi Ikagawa

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: 6986669Abstract: A contact member formed with a flat metal structure and an integrated elastomeric body. The contact member can be used to ground a printed circuit board (PCB) with a surrounding housing. The housing loads the contact member in a direction perpendicular to the face of the PCB. The elastomeric body supports the flat metal structure during repeated cycles of loading and unloading of the contact member. The elastic resiliency of the elastomeric body can help to reduce the effects of plastic deformation of the contact member, resulting in more reliable electrical connections a source outside of the PCB. And the elastomeric body does not require adhesive or separate fixing devices to hold it in place.Type: GrantFiled: March 5, 2004Date of Patent: January 17, 2006Assignee: Kitagawa Industries Co., Ltd.Inventor: Tsutomu Kawai
