Reduced-pair Ethernet patch cords include a twisted pair cable that has a pair of insulated conductors that are contained within a cable jacket. A connector is mounted on a first end of the cable. The connector includes a connector housing and a strain relief unit that is mounted on the cable at the interface between the cable and the connector housing. The strain relief unit includes a plurality of internal protrusions that contact the cable jacket.

A method for litz wire termination includes placing a ferrule over exposed conductors on an end of litz wire. The exposed conductors include a portion of the litz wire without an external insulation layer, and a portion at the end of the litz wire protrude past the ferrule. The method includes crimping the ferrule to the litz wire and placing the end of the litz wire with the ferrule in molten solder past the end of the ferrule. The method includes maintaining the litz wire in the molten solder until insulation on conductors of the litz wire is removed from the conductors in the molten solder and solder bonds to the conductors that are within in the molten solder. The method includes removing the litz wire from the molten solder and allowing the litz wire to cool until molten solder bonded to the conductors transitions to a solid state.

A cable connection structure manufacturing method includes: covering, by a first electrode, an end face of an electric cable, and covering, by a second electrode, a terminal of a substrate; plastically deforming the first electrode and the second electrode having substantially same hardness by first scrubbing in which the first electrode and the second electrode rub against each other at a first pressure and a first amplitude; polishing the first electrode and the second electrode by second scrubbing in which the first electrode and the second electrode rub against each other at a second pressure smaller than the first pressure and a second amplitude smaller than the first amplitude; and bonding the first electrode and the second electrode at a third pressure higher than the first pressure.

Methods of connecting wires (126) to feedthrough pins (104) and apparatus including wires connected to feedthrough pins.

A method of manufacturing an electrical wire connecting structure in which a terminal having a tube-shaped portion and a conductor portion of a covered electrical wire are crimped at the tube-shaped portion, and the tube-shaped portion has a conductor crimping portion corresponding to the conductor portion, and a cover crimping portion corresponding to a cover portion of the covered electrical wire, the method comprising the steps of a) forming the tube-shaped portion, b) inserting the covered electrical wire into a corresponding space, c) crimping a welded portion of the conductor, and d) compressing the cover crimping portion.
