In a terminal connection method of inserting a wire tip of an insulated wire, which is formed by stripping a front end of an insulating cover to expose an aluminum core wire, into a pressure-bonding section of a female crimp terminal to pressure bond the insulated wire to the female crimp terminal via the pressure-bonding section, signs are formed on the outer circumferential face of an insulated tip of the insulating cover at a distance of an internal length of the pressure-bonding section from a conductor tip face of the conductor tip, and the wire tip is inserted up to the signs in the pressure-bonding section to pressure-bond the wire tip to the pressure-bonding section.

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.

There are provided a method for manufacturing an electrical wire with terminal in which a terminal is crimped to a conductor core wire of an electrical wire, the terminal, and the electrical wire with terminal. A crimped portion of the terminal has a tubular shape continuous without a slit in a circumferential direction, and has a shape before crimping in which a tubular inner face of the crimped portion includes a projecting portion protruding into a tubular portion at a cross section orthogonal to an axis of the terminal. The manufacturing method includes: inserting the conductor core wire into the tubular portion of the crimped portion; and crimping the crimped portion to the conductor core wire by caulking the crimped portion using a caulking tool, the caulking tool being configured to deform the crimped portion into the tubular portion by pressing a caulking face against the crimped portion.

A method for assembling cables includes sliding a housing and a sleeve accommodated in the housing onto a cable in such a manner that the sleeve surrounds at least a portion of the cable. The housing is made of an electrically non-conductive material, the sleeve is made of an electrically conductive material and includes a cutting edge pointing radially inward, and the cable includes a conducting element and an insulation surrounding the conducting element. The method further includes magnetically forming the sleeve by applying a magnetic field to the sleeve through the housing, such that the sleeve is pressed against the insulation and the cutting edge penetrates the insulation completely and contacts the conducting element.

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.

A coaxial contact system and a method for electrically connecting a first outer conductor of a first coaxial conductor to a second outer conductor of a second coaxial conductor. The coaxial contact system for electrically connecting a first outer conductor of a first coaxial conductor to a second outer conductor of a second coaxial conductor includes an inner contact sleeve, which forms a support sleeve, and an outer contact sleeve, which at least partially surrounds the inner contact sleeve and forms a crimp sleeve which is crimped around the first and second outer conductors in a final assembled state. The inner contact sleeve and the outer contact sleeve are configured such that the first outer conductor is arranged in an axial direction or a radial direction next to the second outer conductor on the inner contact sleeve.

An inner-conductor contact element for an angled connector has a crimp region which is designed to be connectable to an inner conductor of a cable, and an interface region which is designed to be connectable to an inner-conductor contact element of a counterpart connector corresponding to the angled connector. The inner-conductor contact element also has a connection region which connects the crimp region to the interface region. The inner-conductor contact element is formed in one piece. The connection region has a first transverse extent and a second transverse extent which is smaller, preferably many times smaller, than the first transverse extent. The connection region has an angular shape in a plane formed by the first transverse extent and a longitudinal extent of the connection region.

The present disclosure relates to an electrical cable mechanical connector in the form of a substantially cylindrical body having a longitudinal axis and comprising a solid connecting portion and at least one fitting space, defined by a peripheral wall, as open end of the mechanical connector for inserting an end portion of an electric conductor of at least one electrical cable, wherein the at least one fitting space is divided in a plurality of longitudinal channels, each channel being open for the insertion with contact of a respective fraction of the electric conductor end portion.
