Abstract: A connection system for electrically connecting a cable to a device connector includes a terminal lug having a connecting section having an opening for engaging the terminal lug into a connected state with the device connector. A fixation element fixes the terminal lug in place, in the connected state, on the device connector, with shape fit and/or with force fit, to produce a fixed state. The terminal lug has an elastomer overmolded onto it, at least in the region of its connecting section, that forms a holder having a wall. The fixation element forms a section of a locking unit arranged within the holder in the fixed state, at least in certain sections, that includes a cap element for covering the fixation element, at least in certain sections. The cap element presses against and elastically deforms the wall in the fixed state, at least in certain sections.

Abstract: A method for producing an electrical connection between an electrical conductor, which includes a plurality of individual wires, and a contact element. The electrical conductor is arranged in a contact portion of the contact element, and the contact portion and the electrical conductor are subsequently pressed together so that the contact portion surrounds the electrical conductor. A plurality of mutually spaced elongate welded connections between the contact portion and the electrical conductor are produced by laser irradiation of the contact portion, or by laser irradiation of the electrical conductor through an opening in the contact portion.

Abstract: The invention relates to a cable (1) comprising at least one strand (2) having twisted litz wires (3) for conducting electrical current and an insulation sheath (4) surround inn the at least one strand (2) for electrically insulating the at least one strand (2). The cable (1) has an interruption section (5) without an insulation sheath (4) between two cable sections (6, 6?) with an insulation sheath (4). According to the invention, the twisted weave of the at least one strand (2) is loosened in the interruption section (5), in order to interrupt the transport of moisture through the cable (1), in particular through the at least one strand (2), that results from capillary pressure and/or temperature-related pressure differences along the cable (1), such that the pressure in the interruption section (5) can equalize with that of the exterior.

Abstract: A connection element for an electrical conductor contains a first section to be connected to another component, and a second section having a front surface to be welded to an electrical conductor. The front surface has a three-dimensional form raised in a central region in relation to an edge region surrounding the central region. The connection element is hollow in the region of the front surface.

Abstract: Process for connecting a first electrically conductive component in the form of a flexible electrical line having metal wires to a second electrically conductive metal component, e.g., a second electrical line or a connecting element. The free end of the flexible electrical line is inserted into a sleeve and is pressed with the latter; in addition, the end of the second electrically conductive component that is assigned to the flexible electrical line is inserted into the free end of the sleeve and is brought into contact on the flexible electrical line, and electrical current is run through these two components, by which their ends that lie on one another are melted together, whereby the sleeve is made from such a metal, which has a higher melting point compared to the metal or the metals of the two components that are to be connected to one another.
