  • Tool-less terminal connector for side mount-type battery
    Patent number: 6942526
    Abstract: A tool-less, side mount-type battery terminal connector comprises an elongated conductive body having threads on the inner end sized to engage a threaded female recessed battery terminal, a central cylindrical portion of larger diameter than the inner end, and knob on the outer end. A shoulder at the junction of the inner end and the central cylindrical portion functions to clamp an end terminal of an electrical cable to the battery terminal. The knob is sized to facilitate manual, tool-less rotation of the body.

  • Male-type electrical terminal
    Patent number: 5775963
    Abstract: A male-type terminal end portion comprising a relatively thin, flat metal strip having two sides and a proximal end and a plurality of longitudinally spaced apart indentations extending along the longitudinal axis to the proximal end. The indentations have a preselected depth to thus form an effective thickness equal to the sum of the preselected depth and preselected thickness of the metal strip.
