  • Patent number: 7494362
    Abstract: A connector plug assembly includes a body member, a first threaded shaft portion, a second threaded shaft portion, an electrically-conductive inner sleeve and an electrically-insulative outer sleeve. The body member extends along and about a longitudinal axis and has a first body member end surface, an opposite second body member end surface and an outer surface disposed between the first and second body member end surfaces. The first threaded shaft portion projects from the first body member end surface and the second threaded shaft portion projects from the second body member end surface. The first and second threaded shafts extend along and about the longitudinal axis. The inner sleeve extends along and about the longitudinal axis and the inner sleeve is connected to and surrounds the body member. The outer sleeve extends along and about the longitudinal axis and the outer sleeve is connected to and surrounds the inner sleeve.

  • Patent number: 4068291
    Abstract: A standard solid electrolyte capacitor body having an outer surface of graphite and an anode lead has a novel cathode lead structure. A "c" shaped thin strip portion of the cathode lead is formed about the body and has a solder connection made therebetween. A wire-lead portion of the cathode lead extends away from the body in a parallel direction to that of the anode lead. The cup or "c" shaped portion of the cathode lead makes possible the easy registration of lead to body prior to soldering, even when tiny bodies are employed, which is especially effective during the large batch manufacturing steps in the mass production of capacitors.
