The height (F) of a protruding portion (7) is less than the thickness of a crimping portion (5) before crimping. If the height of the protruding portion (7) is greater than the thickness of the crimping portion, then a recess is prone to form in the inner surface of the crimping portion (5). In other words, because there is more metal flowing outwards, a recess corresponding to the metal flow is prone to form on the inner surface side. If such a recess does form, adhesion with a covered area (27) is likely to deteriorate. This is problematic because such a gap would be a path allowing the ingress of moisture. On the other hand, if the height of the protruding portion (7) is less than the thickness of the crimping portion (5) before crimping, then when the crimping portion (5) is compressed during crimping, the amount of metal flowing towards the protruding portion (7) diminishes, making it possible to suppress the formation of a receding portion on the inner surface of the crimping portion (5).

The invention relates to a connection element for electrically connecting an individual line which has a concentric conductor arrangement (32) and a central passage (33) for a cooling fluid. The connection element comprises an electrically conductive housing (2) with a sleeve-shaped pressing portion which is suitable for producing a press connection to the concentric conductor arrangement (32). The electrically conductive housing (2) here has an internal cooling passage (10) with a connection opening (11) for an external cooling line, said cooling passage leading into a space surrounded by the sleeve-shaped pressing portion. In addition, the connection element comprises a counterpressure element (3) which can at least partially lie in the space surrounded by the sleeve-shaped pressing portion. The counterpressure element (3) is furthermore configured to support the concentric conductor arrangement (32) on the inner side thereof when the sleeve-shaped pressing portion is compressed during the production of a press connection. The invention furthermore relates to a fluid-coolable individual line unit and to a charging cable having a charging connector.

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 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 electrical connector assembly includes an electrical connector having a conductor receiving portion. The conductor receiving portion defines a cavity. The electrical connector assembly further includes a capsule positioned within the cavity of the conductor receiving portion. The capsule contains oxide inhibitor. The capsule is configured to release the oxide inhibitor into the cavity of the conductor receiving portion.

The objective of the present invention is to prevent a deterioration in communication performance A shielded electrically conductive path (A) is provided with a shielded terminal (25) including an inner conductor (26), and an outer conductor (28) enclosing the inner conductor (26), a shielded electric cable (10) including a core wire (12) affixed to a rear end portion of the inner conductor (26), a braided wire (15) enclosing the core wire (12), and a sheath (18) enclosing the braided wire (15), and a sleeve (20) attached to the outer circumference of a front end portion of the sheath (18), wherein, in the front end portion of the shielded electric cable (10): the braided wire (15) extending from a front end (18F) of the sheath (18) is folded back toward the rear to cover the outer circumference of the sleeve (20); a crimping portion (30) of the rear end portion of the outer conductor (28) is crimped to the sleeve (20) while enclosing the outer circumference of a folded back portion (17) of the braided wire (15); and a front end (20F) of the sleeve (20) is positioned forward of the front end (18F) of the sheath (18) in the front-rear direction.

It is aimed to externally fit a sleeve formed into a tubular shape to a braided wire. A mounting device is a device for mounting a tubular sleeve on a coaxial cable having a front end part of a braided wire exposed in front of a sheath to externally fit the sleeve to the braided wire, and is provided with an expansion restricting jig including an expansion restricting portion for restricting expansive deformation of the braided wire and relatively displaceable in an axial direction with respect to the braided wire with the expansion restricting portion held in contact with an outer peripheral surface of the braided wire. The expansion restricting jig is formed with a positioning portion for positioning the sleeve concentrically with the braided wire with the sleeve arranged forward of the expansion restricting portion.

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.
