A terminal-equipped electric wire includes an electric wire, a terminal fitting, and a water-stopping member. The terminal fitting includes a bottom wall on which the electric wire end is placed, and a pair of core wire caulking pieces caulking and crimping a core wire exposed part in a state where a front end of the core wire exposed part protrudes, and the bottom wall includes a concave part that continues from a place facing the front end side of the core wire exposed part in the pair of core wire caulking pieces to the tip of a front end surface of the front end of the core wire exposed part, and receives the bottom wall side ranging from a place where the core wire exposed part is caulked and crimped by the end parts of the pair of core wire caulking pieces to the front end surface.

A terminal-equipped electric wire includes an electric wire in which a core wire including a plurality of strands is covered with a covering, and a terminal fitting attached to the electric wire. The terminal fitting includes a core wire connection body physically and electrically connected to the core wire. The core wire connection body has a bottom, a pair of cantilever side walls erected from the bottom and arranged facing each other with a space therebetween, and at least one set of paired pressure contact bodies arranged facing each other with a space therebetween between the pair of side walls so as to come into pressure contact with the strands in an outermost layer of the core wire.

Contact system for producing an electrically conductive contact between an aluminum conductor (3) and a contact component (2). A housing (1) is provided, as well as a contact component (2) having a shearing section (13) and a tapered compression segment (14), where the housing (1) has an insertion volume (4) for the aluminum conductor (3) and an insertion volume (5) for the contact component (2) and the two insertion volumes (4, 5) overlap within the housing (1) and form a common overlapping volume (8) so as to enable, when the aluminum conductor (3) has been pushed into the insertion volume (4), for the aluminum conductor (3), the severing/shearing and cold welding of the aluminum conductor (3) with the contact component (2) by means of the contact component (2).

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.

Disclosed is an elastic electric contact terminal comprising: an elastic core; a polymer film which is bonded while covering the core, with an adhesive layer being interposed therebetween; and a copper foil capable of being soldered, which is bonded while covering the polymer film. A metal plating layer is formed on every surface exposed outwardly from the copper foil.
