A terminal is provided with a terminal body including a mating connecting portion, a wire connecting portion and a coupling portion, and a shell. The wire connecting portion includes sandwiching portions extending in an extending direction of a wire and configured to sandwich the wire. The shell includes pressurizing portions for pressurizing the sandwiching portions toward the wire. The mating connecting portion includes a mating bottom wall and mating side walls formed to rise upward in a predetermined rising direction from the mating bottom wall. The wire connecting portion includes a wire-side bottom wall and wire-side side walls rising upward in the rising direction from the wire-side bottom wall. The coupling portion is inclined in a direction opposite to the rising direction from the wire-side bottom wall toward the mating bottom wall to couple the wire-side bottom wall and the mating bottom wall.

A crimp ferrule includes an assembly portion assembled on a non-circular internal cross section of a multi-core cable and a diameter compensation portion forming a circular external cross section of the crimp ferrule on the multi-core cable. The assembly portion and the diameter compensation portion are arranged successively in an axial direction of the crimp ferrule.

A telecommunications connector includes a connector body and a shield attached to the connector body, the shield including a main body portion configured for attachment to the connector body and a barrel portion for crimping against a cable to be terminated to the connector. The barrel portion of the shield includes a corrugated side wall made up of a series of bends extending along a direction from the rear end of the barrel toward the front end of the barrel along at least a portion of a length of the barrel, wherein the bends defining the corrugated side wall are provided on the shield at a pre-crimped stage.

An electrical assembly includes a terminal having a terminal body, a first wing extending from the terminal body, and/or a second wing extending from the terminal body. An electrical assembly may include a conductor in electrical contact with the first wing. The conductor may include a conductive layer and/or an insulative layer. An inner surface of the first wing and/or an outer surface of the first wing may be in direct contact with the conductive layer of the conductor.

A manufacturing method for an electric wire having a terminal includes a step of connecting a plurality of core wires by an ultrasonic connection process to form a connected core wire. In the step, the core wires are formed into the connected core wire having a cross-sectional shape having a width and a height in a plane orthogonal to an axis of the connected core wire, the width is not longer than a length obtained by subtracting two times a thickness of the terminal from a width of an arch groove of a crimper of a crimping apparatus in a state that a space between a support surface of an anvil of the crimping apparatus and the arch groove defines a predetermined crimped shape.

An electric machine having a rotor, stator and at least one winding. The winding defines a first lead having a conductive core and an electrically insulative exterior layer. A connector engaged with the first lead includes a plurality of projections that pierce the exterior layer of the first lead to engage the conductive core. The connector may be C-shaped having a spine and first and second arms with first and second bend lines respectively disposed between the spine and the two arms. Alternatively, the connector may be U-shaped having a spine and first and first and second arms wherein a bend line and a central opening are disposed between the two arms. The first lead extends through the central opening and is grippingly engaged by the connector between the first and second arms. The connector may also be used to securely engage an uninsulated terminal.

A covered conductive wire is configured by covering a conductive wire with an insulating cover portion. The conductive wire is formed of an aluminum-based material, for example. A crimping portion includes a cover crimping portion for crimping the cover portion of the covered conductive wire, and a conductor crimping portion for crimping a portion of the conductive wire that is exposed when the cover portion is removed at the tip portion of the covered conductive wire. It is possible to use polyvinyl chloride and/or a non-halogen member, for example, for the cover portion of the covered conductive wire, and a plasticizer, filler, stabilizer, or the like is compounded as needed. A material that shrinks by a factor of 7% or less after being allowed to stand for 120 hours at a high temperature of 120° C. is used for this cover portion.

This disclosure addresses the problem of aluminum and in particular stranded aluminum wires, which generally do not well bond to other metals such as e.g. copper or brass. In the long term, transition resistance changes, in particular under the influence of oxygen and due to the energizing with high currents. There is also a need for high-current connectors that can be flexibly strapped and field-wired. This disclosure provides a heavy-duty plug-type connector having at least one crimp contact, the transition between a crimping region formed of aluminum and a contact region formed of copper being shifted to the cylindrical or at least rotationally symmetric crimp contact. The stranded wire can thus be crimped with the crimp contact without the aforementioned problems. Furthermore, an additional inner thread and a pin that the can screwed into it are provided in the crimping region.

A crimp-connection structural body, a wire harness, a method of manufacturing a crimp-connection structural body, and a manufacturing device are provided. The crimp-connection structural body includes an insulated wire formed by covering a conductor by an insulating cover, and a crimp terminal having a crimp section allowing connection by crimp of a conductor exposed portion formed by exposing the conductor. The crimp section is formed of a closed-barrel-type crimp section, and a cross-sectional shape of the crimp section in a radial direction is formed into an approximately recessed cross-sectional shape having a crimp recessed portion formed by indenting by inclined portions inclined from positions spaced-apart from each other by a predetermined distance. The predetermined distance is set to 90% or less of an entire width of the crimp section. An opposedly facing angle made by the inclined portions is set to a value which ranges from 10° to 120° inclusive.

A terminal is provided with a terminal body including a mating connecting portion, a wire connecting portion and a coupling portion, and a shell. The wire connecting portion includes sandwiching portions extending in an extending direction of a wire and configured to sandwich the wire. The shell includes pressurizing portions for pressurizing the sandwiching portions toward the wire. The mating connecting portion includes a mating bottom wall and mating side walls formed to rise upward in a predetermined rising direction from the mating bottom wall. The wire connecting portion includes a wire-side bottom wall and wire-side side walls rising upward in the rising direction from the wire-side bottom wall. The coupling portion is inclined in a direction opposite to the rising direction from the wire-side bottom wall toward the mating bottom wall to couple the wire-side bottom wall and the mating bottom wall.
