A medical lead may be fabricated using an electrode fixture configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method may include positioning an electrode fixture around at least one conductor of a plurality of conductors for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method may also include electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

A medical lead may be fabricated using an electrode fixture ((130A)-(130D)) configured to facilitate circumferential and axial alignment between electrodes of the lead. In one example, a method includes positioning an electrode fixture around at least one conductor of a plurality of conductors (122) for a medical lead, wherein the electrode fixture at least partially retains an electrode assembly. The method also includes electrically coupling a portion of the at least one conductor with at least a portion of the electrode assembly at an attachment area defined by the electrode assembly when the electrode assembly is at least partially retained by the electrode fixture.

A system for multi-stage crimping of a contact to a wire includes a first crimping die having a first portion of a selected shape defined therein, and a second crimping die having a complementary second portion of the selected shape defined therein. The system also includes the first and second crimping dies being operable to be displaced towards each other and along a first axis during a compression stroke. The first and second crimping dies are also operable to be displaced along a second axis during a closing stroke subsequent to the compression stroke, where the second axis is generally perpendicular to the first axis. In addition, the system includes the first and second crimping dies cooperating to crimp the contact into the selected shape to the wire upon completion of the closing stroke.

A terminal crimping method includes covering an end portion of an electric wire with a fixing cylinder portion of a terminal including a flange portion which protrudes toward an outer periphery and which has at least one notch along a radial direction, caulking and crimping the fixing cylinder portion by a pair of dies including pressing projections, and caulking the fixing cylinder portion by the pressing projections to form crimp recess portions, in the caulking and crimping the fixing cylinder portion.

A handheld hydraulically actuatable crimping device includes a hydraulic piston that can be displaced in a cylinder against the force of a spring. The piston is connected to a crimping part by a piston rod in order to carry out a crimping operation. The piston includes first and second partial pistons with first and second partial application faces which can be acted upon with hydraulic medium that has the same hydraulic pressure. Both partial pistons are respectively connected to a first and a second crimping part. The second crimping part can at a greater traveling distance only be acted upon with the second partial piston. The second crimping part can be acted upon with both partial pistons over a first partial traveling distance that is defined by the displacement of the first partial piston from its initial position up to the point, at which it reaches a stop. The first crimping part is axially covered in its entirety by the second crimping part.

A die extended in the service life. An anvil includes a base portion and a protruding portion, and further, includes a wall portion that is connected to rear surfaces of the base portion and the protruding portion. The wall portion extends further upward than the base portion, and extends further leftward and rightward than the protruding portion. Therefore, the rigidity of the protruding portion in a left-right direction is high.

A terminal crimping apparatus includes a terminal supply device configured to supply a terminal chain member including a plurality of crimping terminals, a first mold including a first edge portion provided at one end of a supporting surface supporting the crimping terminals, a second mold configured to crimp the crimping terminal onto a wire by sandwiching the crimping terminal between the second mold and the supporting surface, and a terminal cutting member including a second edge portion. The terminal cutting member cuts a boundary with the crimping terminal in a link portion using the second edge portion.

A coaxial connector for interconnection with a coaxial cable with a solid outer conductor by ultrasonic welding is provided with a monolithic connector body with a bore. An annular flare seat is angled radially outward from the bore toward a connector end of the connector, the annular flare seat open to the connector end of the connector. An inner conductor cap is provided for interconnection with an inner conductor of the coaxial cable by ultrasonic welding. The ultrasonic welding of each of the inner and outer conductor interconnections may be performed via inner conductor and outer conductor sonotrodes which are coaxial with one another, without requiring the cable and or connector to be removed from their fixture.

The invention provides a method for applying an electrical terminal to one or more conductors, possibly provided with an external electrical insulation layer, comprising the following steps: placing the end portions of the conductors in a housing portion of the terminal; applying heat and pressure in such a way as to compact and/or join the end portions of the conductors and the housing portion of the electrical terminal and to remove any respective electrical insulation layers at least at the level of the housing portion of the electrical terminal. The application of pressure and heat causes the opposite walls to close on the end portions of the conductors. Said electrical terminal comprises an electrical connection portion that extends from the housing portion. The invention also concerns a device or piece of equipment for the application of an electrical terminal, a metal element and an electrical terminal.
