  • Patent number: 10008707
    Abstract: There is disclosed a battery module that includes a housing. At least one terminal is melt joined with the bus member of the housing sealing the terminal relative to the bus member and providing a conductive path to an interior of the battery module. The terminal may be melt joined in an ultrasonic joining operation or in a thermal insertion operation. A plurality of cells are disposed in the housing with each of the cells electrically coupled via bus bars integrated into a bus member. Each of the cells includes a plurality of positive and negative electrodes that are spaced by a separator. The negative electrode includes a substrate having tab meeting at a flange that is connected to an active material portion of the electrode. The positive electrode includes a substrate having a tab meeting at a flange that is connected to an active material portion of the electrode.

  • Patent number: 4382242
    Abstract: A solenoid operated switch that has a cover formed of insulating material secured to the end of a metallic solenoid housing. A pair of internally threaded mounting studs fixed to the solenoid housing extend through openings in the cover and receive threaded screws. The screws have heads engaging the cover and are tightened against the ends of the mounting studs. A rubber coated spring steel gasket is located between the cover and solenoid housing which is flexed from a straight configuration to a bowed configuration when the screws are fully tightened.
