An aluminum foil terminal of one battery is sandwiched between the conductive spring and the pocket of the first retaining member, while a copper foil terminal of another battery is sandwiched between the conductive spring and the pocket of the second retaining member. The spring member is clad with aluminum on one side and copper on the other, and the end portions are oppositely curved so that the aluminum-clad side contacts the aluminum foil terminal within the pocket of the first retaining member, and the copper-clad side contacts the copper foil terminal within the pocket of the second retaining member.Type: GrantFiled: December 9, 2008Date of Patent: October 26, 2010Assignee: Delphi Technologies, Inc.Inventors: Duane D. Kruger, Robert C. Beer

Publication number: 20100261045Abstract: Methods and apparatus supporting an electrical connection are disclosed. Systems previously equipped with wire interfaces, such as battery terminals, can be equipped with a connector assembly to significantly reduce a hazard of electrical shock to a user. The connector assembly includes a stress relief component that attenuates a force, applied to the stress relief component, to reduce its effect on the connector assembly. By attenuating the force, the connector assembly maintains a substantially fixed position relative to the battery pack component and mitigates a potential for disruption in electrical connectivity. Techniques disclosed herein benefit users of battery packs or other devices as well as manufacturers by increasing safety, reliability, and ergonomics.Type: ApplicationFiled: April 13, 2009Publication date: October 14, 2010Inventors: Wen-Sung Wu, Meng-Chang Liu, Shen-Yuan Chien

Patent number: 7785150Abstract: A battery connector includes an insulating housing and a plurality of conductive terminals disposed in the insulating housing. The insulating housing defines a plurality of terminal recesses each extending longitudinally to penetrate through a bottom and a mating surface thereof. A top of each of the terminal recesses defines a locating passageway extending longitudinally. The conductive terminals are disposed in the corresponding terminal recesses. Each of the conductive terminals has a base board. A contact portion projects out of the mating surface of the insulating housing and an elastic portion elastically connects the contact portion to the base board. A portion of an edge of the elastic portion extends upward to form a locating portion slidably moving along the corresponding locating passageway so as to limit the movement area of the conductive terminal and avoid the conductive terminal swaying in the terminal recess.Type: GrantFiled: May 15, 2009Date of Patent: August 31, 2010Assignee: Cheng Uei Precision Industry Co., Ltd.Inventor: Hsin-Tsung Ho

Patent number: 7785158Abstract: An electrode connection platform is made of an electrically conductive material, such as brass, and configured to allow multiple electrical conductors to be rigidly and securely attached to its upper surfaces. The platform is attachable to a terminal of a storage battery. Upper surfaces of the platform are arranged so that interference between electrical conductors is minimized. The platform, with all of its attached electrical conductors, can be removed from a terminal post of a storage battery without necessitating the disconnection of any of the electrical conductors from the platform.Type: GrantFiled: November 30, 2007Date of Patent: August 31, 2010Assignee: Brunswick CorporationInventors: David F. McCoy, Steven J. Gonring

Patent number: 7754374Abstract: The disclosure is directed to a battery assembly that includes a protective cover. The protective cover is positioned over a side plate that includes connections, such as a bus bar and a fixing member, that allow for battery operation. One or more flexible openings within the protective cover open to accept the fixing member, such as a screw or bolt, and close once the fixing member has passed. In this manner, the flexible opening allows for easy assembly and maintenance of the battery assembly while providing a mechanism of protecting the battery components from environmental elements. In addition, the flexible opening may be made by one or more cuts in the protective cover, wherein material elasticity enables the flexible opening to open and close.Type: GrantFiled: January 17, 2006Date of Patent: July 13, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Osamu Hashida, Takeyuki Kokubo
