An electrical crimp ferrule includes a circumferential center portion, a first circumferential flank connected to the center portion, and a second circumferential flank connected to the center portion. The circumferential center portion integrally connects the first and second circumferential flanks. At least one crimp diameter compensation element extends from at least one of the first circumferential flank or the second circumferential flank and is adapted to engage with an electrical cable having a non-circular cross section in a crimped state of the ferrule.

A crimp terminal (1) includes a barrel (13) on which a recessed serration (14) is formed, the barrel is to be bent and crimped to a conductor portion (21) of a wire (2), and the shape of an outer edge of the serration (14) is formed so that arcs (A1 to A4) each of which is convex outward continue to each other.

A terminal connector for connecting to a conductor, the terminal connector including a conductor portion, a lug portion and a terminal insert extending into the conductor portion. The terminal insert receives the conductor. The terminal insert includes one or more inwardly extending coating piercing members. The one or more coating piercing members are capable of penetrating non-conductive coatings on the conductor.

A terminal assembly includes a terminal having a wire barrel and a mating segment configured to be mated to a mating component. The terminal assembly includes a shuttle assembly configured to be coupled to an end of a wire. The shuttle assembly includes a connecting insert defining a wire chamber configured to receive an exposed conductor of the wire. The connecting insert has a retention tab extending into the wire chamber. The retention tab is configured to interfere with and retain the wire in the wire chamber. The connecting insert is received in the wire barrel of the terminal and the connecting insert is configured to be crimped between the wire barrel of the terminal and the exposed conductor of the wire when the wire barrel is crimped around the connecting insert and the wire.

A crimp connection system for electrical cables, including an electrical cable having a stripped cable end and a fastening sleeve. The stripped cable end is arranged at least partially within the fastening sleeve. The fastening sleeve has a number of fastening protrusions extending from the interior and/or outer surfaces of the fastening sleeve. The fastening protrusions are distributed over the interior and/or outer surfaces of the fastening sleeve. The crimp connection system also includes a contact terminal having a crimp portion. The fastening sleeve is arranged at least partially within the crimp portion.

A connection structure of a wire harness enables the wire harness to be severed in the event of a vehicle collision. End portions of electric wires are respectively provided with connection end portions in which conductors of the end portions have been subjected to fusing processing, the connection end portion has an extension portion and a protruding portion, the protruding portion is at least partially provided with a tapered portion, the connection end portions are integrally connected to each other by crimping the extension portions from the radial-direction outer side by the connecting member, and at the connection end portion, the crimping of an extension portion to press the tapered portion inserted in a concave portion causes the engagement force between the extension portion and the connecting member to become weaker than the engagement force between the extension portion and the connecting member when applying tension to the electric wires.

A terminal-equipped electric wire includes an electric wire in which a core wire made of aluminum or an aluminum alloy is covered with a covering, and a terminal fitting made of copper or a copper alloy and crimped to an end portion of the electric wire in which the core wire is exposed. The terminal fitting includes a pair of crimp pieces. End portions of the pair of the crimped portions are crimped in a state where the end portions of the pair of the crimped portions are overlapped with each other, so as to cover a surrounding of the electric wire from a leading end of the core wire to a part of the covering. At least the pair of the crimp pieces have top surfaces, bottom surfaces and side surfaces covered with anti-corrosive plated layers.

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.

A crimping die includes a first die for constraining the wire crimping portion by a concave die surface shaped in conformity with the wire crimping portion, and a second die including a convex die surface paired with the concave die surface. A width of a recess on the concave die surface and that of a projection on the convex die surface are equal to an outer diameter of the wire crimping portion. The wire crimping portion is pressed by the concave die surface of the first die and the convex die surface of the second die, whereby the wire crimping portion and the wire inserted into the cylindrical interior of the wire crimping portion are crimped and fixed.
