  • Patent number: 8000803
    Abstract: The invention is a lead attachment suitable for implantation in living tissue that enables connection of a wire that is comprised of stainless steel to a tack that in turn is bonded to a titanium swage cup, preferably Ti-6Al-4V. The wire is attached by crimping inside a crimping tube, to assure electrical continuity from the wire to the crimping tube. The tack is bonded by swaging a thinned swage ring and is further sealed by welding to swage cup, which is bonded by brazing to ceramic case.

  • Patent number: 7955147
    Abstract: An surface mount technology (“SMT”) crimp terminal for mounting on printed circuit boards is in the form of a seamless circular tube or cylinder. The method of use includes depositing the SMT crimp terminal on a copper pad or land on a printed circuit board (“PCB”) coated with solder paste to render the pad or land tacky. The solder is reflowed by application of heat and the crimp terminal is soldered to the PCB. A bare wire to be retained is inserted through one end of the tube and the tube is subjected to sufficiently high stress, intermediate its axial ends, to induce plastic flow on the surface of the material. The force plastically deforms the central region of the tube as well as the bare wire received therein. Any form of mechanical hydraulic press can be used for this purpose and resulting deformation of the crimp terminal and the wire contained therein provides a retention force on the wire which is greater than wire breaking strength.

  • Publication number: 20100261391
    Abstract: Provided is a technique of ensuring mechanical strength in a terminal-provided wire and lowering contact resistance between the wire and the crimp terminal, without greatly varying a crimp height of a crimp terminal onto the wire in an axial direction. A crimp terminal according to the invention includes a conductor barrel which is crimped to a conductor of a wire. The conductor barrel has an inner surface which closely contacts the conductor by bending. The inner surface has such a shape a surface thereof which closely contacts a tip end side part of the conductor inwardly projects beyond a surface thereof which closely contacts a base side part of the conductor, thus performing a higher compression of the tip end side part of the conductor than that of the base side part thereof by the bending.
