This disclosure relates to a method for connecting a strand element to a connection element using a re-shaping method, such as a connecting a cable lug. A system is also disclosed which comprises a pair of receiving elements having a front side with a recess and a hollow section. The hollow section is designed to accommodate a press insert having a front side with a recess. The receiving element and the press inserts are arranged in a vice. The system also comprises a clamp having a front side with a recess, which is suitable for receiving the connection element. When a pair of receiving elements is arranged, together with the press insert, around a central region of the connection element, then a re-shaping connection, such as a crimp connection, is produced between the strand element and the connection element.

A system for multi-stage crimping of a contact to a wire includes a first crimping die having a first portion of a selected shape defined therein, and a second crimping die having a complementary second portion of the selected shape defined therein. The system also includes the first and second crimping dies being operable to be displaced towards each other and along a first axis during a compression stroke. The first and second crimping dies are also operable to be displaced along a second axis during a closing stroke subsequent to the compression stroke, where the second axis is generally perpendicular to the first axis. In addition, the system includes the first and second crimping dies cooperating to crimp the contact into the selected shape to the wire upon completion of the closing stroke.

A crimping tool is disclosed. The crimping tool includes a base, an operating member and a moving member. The base includes a pivot location, a sliding groove, and first and second fixing locations. The first and second fixing locations are respectively located on two ends of the sliding groove to fix a connector of a wire. The operating member includes a holding portion, a pivot hole and a gear. The pivot hole is pivotally connected to the pivot location of the base through a pivot shaft. The moving member includes a rack, and first and second crimping elements. When the operating member rotates, the gear drives the rack to enable the moving member to move simultaneously, so as to use the first or second crimping element to press fit the connector of the wire placed at the first or second fixing location.

An aluminum electric wire crimping terminal formed by connecting an aluminum electric wire and a crimping terminal includes a low compression concave portion and a high compression concave portion in a crimping portion. The high compression concave portion compresses a plurality of core wires with a stronger compression force than a compression force of the low compression concave portion.

Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.

A method provides for producing a cable connection assembly including an electrical cable connected to a cable connector. The cable connector is positioned on a conductor end portion, so that a portion of the insulating layer is at least partially surrounded by the cable connector. The conductor end portion is disposed within a fastening tube, so that a first tube portion of the fastening tube surrounds the cable connector, and a second tube portion of the fastening tube surrounds the cable jacket. The fastening tube is pressed between strip-shaped pressing surfaces which are disposed around a central axis at a constant distance therefrom. During the pressing step, the first tube portion is pressed to a first inner diameter and the second tube portion is pressed to a second inner diameter greater than the first inner diameter.
