The multicore cable manufacturing apparatus includes a plurality of crimping dies, each crimping die being constituted of a pair of dies to connect, by crimping, each electric wire and each terminal. The plurality of crimping dies is configured to substantially simultaneously connect the plurality of electric wires and the plurality of terminals, and the crimping die is configured to connect a front end portion of each electric wire and each terminal with the front end portions of the plurality of electric wires extending radially centering on a branch point located on a rear side of the front end portion.

A wire crimping device includes: a wire crimping unit which crimps a crimping section into which a wire tip is inserted from a wire insertion opening which opens on a proximal end side of the crimping section in a long length direction; and a guiding unit which guides a distal end portion of an aluminum lead line to the wire insertion opening of a female crimp terminal arranged at a predetermined position for being crimped by the wire crimping unit, wherein an inner diameter of an opposedly facing portion of the guiding unit which opposedly faces the wire insertion opening is set in conformity with an inner diameter of the wire insertion opening.

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.

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 cable processing apparatus includes a trimming and insulation stripping unit with cutting blades for severing the cable, first insulation-stripping blades for stripping insulation from a rear end of the severed cable piece, and second insulation-stripping blades for stripping insulation from a front end of the remainder of the cable, and a crimping press with a first crimping tool for connecting the rear end of the trimmed cable piece to a first crimp contact and with a second crimping tool for connecting the front end of the remainder of the cable to a second crimp contact. A lifting element formed by a carriage and displaceably mounted on a machine housing of the cable processing apparatus operate both the trimming and insulation-stripping unit and the first and second crimping tools. The lifting element is moved up and down by an eccentric shaft driven by a motor.

A manufacturing method of a crimping terminal includes a terminal supply step of supplying the crimping terminal to a crimping position with a wire by a terminal supply device, the crimping terminal including a terminal connection portion, a wire connection portion to be crimped onto the wire, and a joint portion linking side walls of the terminal connection portion and the wire connection portion, a support step of supporting a bottom portion of the crimping terminal supplied to the crimping position by a first mold, a crimp step of deforming the wire connection portion while relatively moving toward the first mold, and crimping the wire connection portion onto the wire by a second mold, and a regulation step of regulating a width of the joint portion so as not to be wider than a width of the terminal connection portion, by sandwiching the joint portion from both sides in a width direction when the second mold crimps the wire connection portion by a regulation portion.

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.

A method for assembling a cable connector which has an outer conductor part, and insulating part and an electrical cable that is prefabricated with an inner conductor part. In a first method step, the insulating part is introduced into the outer conductor part by relative movement between the insulating part and the outer conductor part. In a second method step, before or at least partially during the first method step, the electrical cable is prefabricated to have an inner conductor part secured on an inner conductor of the cable. In a third method step, during or after the first method step, the prefabricated cable is introduced into the insulating part up to a defined axial terminal position. The positions of the inner conductor part, the outer conductor part and/or the insulating part are fixed relative to each other by compressing the outer conductor part at least partly.

A coaxial connector fore 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.
