A crimping die including a first die piece having a recess portion and a second die piece having a protrusion portion is provided. An inner wall surface of the recess portion has a bottom wall surface and recess-side lateral end surfaces. An outer surface of the protrusion portion has a top end surface and protrusion-side lateral end surfaces. The bottom wall surface has a recess-side projection portion, a recess-side concave portion, and a recess-side curvature changing portion. The top end surface has a protrusion-side projection portion, a protrusion-side concave portion, and a protrusion-side curvature changing portion. A sign of curvature of the bottom wall surface changes at a boundary portion in the recess-side curvature changing portion with respect to the recess-side concave portion. A sign of curvature of the top end surface changes at a boundary portion in the protrusion-side curvature changing portion with respect to the protrusion-side concave portion.

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 wire connection part of a terminal fitting includes: a barrel piece which is caulked while covering a tip end of a wire, thereby being crimped to the wire; a serration part formed on an inner surface of the barrel piece and connected to a core of the wire; and a water stop part mounted on the inner surface of the barrel piece to close a gap with the wire. A projecting piece mounted anterior to the serration part to position a tip end of the core is mounted to the barrel piece. The tip end of the core is positioned by the projecting piece, whereby the positional deviation of the wire can be prevented.

An electric connector terminal assembly which allows numerous different terminal connector ends and wire diameters to be connected to a single size and type crimp cylinder using an rolled metal strip insert. Preferably, the metal strip is made of copper, and preferably the copper strip is coated with tin. The metal strip is then formed into a cylinder for insertion to the crimp cylinder. A method for connecting a crimp terminal to an electric wire is also disclosed. The method requires cutting a metal strip to form a plurality of parallel compliant members (e.g., fingers) connected to a base, rolling the cut strip to form a cylindrical insert, positioning the insert within a crimp cylinder of an electric connector with the fingers extending toward the mating end, inserting an electric wire within the cylindrical insert, and crimping the crimp cylinder to secure the electric wire within the cylindrical insert and crimp cylinder.

A crimping die including a first die piece having a recess portion and a second die piece having a protrusion portion is provided. An inner wall surface of the recess portion has a bottom wall surface and recess-side lateral end surfaces. An outer surface of the protrusion portion has a top end surface and protrusion-side lateral end surfaces. The bottom wall surface has a recess-side projection portion, a recess-side concave portion, and a recess-side curvature changing portion. The top end surface has a protrusion-side projection portion, a protrusion-side concave portion, and a protrusion-side curvature changing portion. A sign of curvature of the bottom wall surface changes at a boundary portion in the recess-side curvature changing portion with respect to the recess-side concave portion. A sign of curvature of the top end surface changes at a boundary portion in the protrusion-side curvature changing portion with respect to the protrusion-side concave portion.

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 method for connecting a conductor and a conductor connector accessory includes inserting an end portion of the conductor into an interior of a tube, and inserting the tube into an interior of a barrel. The barrel defines a plurality of radial passages extending between an outer surface of the barrel and the interior of the barrel. The method further includes providing a plurality of lobes, each of the plurality of lobes disposed within one of the plurality of passages. The method further includes inserting the barrel into an interior of an outer shell, and compressing the outer shell, barrel, lobes, tube and end portion together.

An electrical connector includes a contact pin to be connected to a core wire of a coaxial cable, an insulating housing for holding the contact pin therein, a cylindrical outer contact covering the housing and a crimping member for attaching the outer contact to the coaxial cable. A base end portion of the outer contact is located between an inner insulator layer and an outer conductor layer of the coaxial cable. The outer contact is attached to the coaxial cable by crimping the crimping member onto the outer conductor layer of the coaxial cable located on the base end portion of the outer contact.

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.
