A wire bonding method includes: arranging a first core including a plurality of strands exposed from an insulating sheath of a first wire, onto a side of an anvil and a second core including a plurality of strands exposed from an insulating sheath of a second wire, onto a side of a horn for ultrasonic bonding, the second core being larger in sectional area than the first core; and bonding the first core and the second core together by ultrasonic bonding between the horn and the anvil.

The invention relates to a cable assembly comprising at least three electric cables which have electric conductors that are electrically and mechanically connected together. Each of the electric conductors is free of an insulation material and is plate-shaped in a contact point. One of the cables is designed as a support cable, and the electric conductor of the support cable is formed as a support plate at the contact point in order to attach the contact points of the other electric conductors. Multiple contact points of the other electric conductors are secured to a surface of the support plate next to one another.

A wire harness that includes a connector in which a connection end of a single-core wire electrical cable and a connection end of a twisted wire electrical cable are welded to each other and are covered by a heat shrinkable tube, wherein the connector includes a separator between the connection end of the twisted wire electrical cable and the heat shrinkable tube, the separator being made of metal and being configured to separate the connection end of the twisted wire electrical cable from the heat shrinkable tube.

A method for establishing a plug connection, and a method for strengthening a plug connection, wherein a connecting zone is welded with a laser beam which passes through a surrounding housing owing to transparency.

The present disclosure relates to a joining method for a terminal-equipped electric wire in which a plurality of terminal-equipped electric wires including a first terminal-equipped electric wire and a second terminal-equipped electric wire are joined each other. The joining method includes a first step of placing at least a conductor core wire of the first terminal-equipped electric wire among the plurality of terminal-equipped electric wires on a horn and crushing the conductor core wire of the first terminal-equipped electric wire by the horn and an anvil, and a second step of placing a conductor core wire of at least the second terminal-equipped electric wire among the plurality of terminal-equipped electric wires on the crushed conductor core wire and ultrasonically joining the conductor core wires by the horn and the anvil.

A method of joining at least two substrates includes welding the at least two substrates together with a multi-step welding process. The multi-step welding process includes: reducing a mismatch between the at least two substrates by melting on both sides of the at least two substrates to form a melted portion that does not overlap a joint line between the at least two substrates with a first welding step; and increasing melt volume and penetration depth of the melted portion between the at least two substrates with a second welding step.

A branching circuit body includes a first electric wire, a first shield tube which covers the first electric wire, a second electric wire which is electrically connected to the first electric wire and drawn out through an opening formed in the first shield tube, a second shield tube which covers the second electric wire and has an end portion inserted into the opening, and a coupling band for joining the second shield tube to the first shield tube.

A system for transmitting power and current includes a power cable having stranded wires and an exposed end. The stranded wires are ultrasonically welded together. Ultrasonically welding the wires creates a bundle of wires at the exposed end that may be free from air pockets, reducing oxidation and improving the current path through the cable.
