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. The elongate welded connections extend in an irradiation direction from an irradiated region of the contact portion, or from an irradiated region of the electrical conductor, through an entire cross-section of the pressed electrical conductor to a region of the contact portion opposite to the irradiated region, such that the electrical conductor is connected to this area of the contact portion; and the irradiated regions are arranged in the form of a grid.
A method for producing an electrical connection between an electrical conductor comprising a plurality of individual wires and a contact element, wherein 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, wherein by laser irradiation of the contact portion, or by laser irradiation of the electrical conductor through an opening in the contact portion, a plurality of elongate welded connections spaced apart from one another are produced between the contact portion and the electrical conductor, wherein the elongate welded connections each extend in an irradiation direction from an irradiated region of the contact portion, or from an irradiated region of the electrical conductor, through an entire cross-section of the pressed electrical conductor to an area of the contact portion opposite to the irradiated region so that the electrical conductor is connected to this area of the contact portion, wherein the irradiated regions are arranged in a grid.
A device for producing an electrical connection between an electrical conductor comprising a plurality of individual wires and a contact element, the device comprising a pressing tool with which the electrical conductor arranged in a contact portion of the contact element can be pressed with the contact element so that the contact portion surrounds the electrical conductor,
A unit with an electrical conductor comprising a plurality of individual wires and a contact element, wherein the electrical conductor is arranged in a contact portion of the contact element and the contact portion and the electrical conductor are pressed together so that the contact portion surrounds the electrical conductor and an electrical connection exists between the electrical conductor and the contact element, wherein a plurality of mutually spaced elongate welded connections are present between the contact portion and the electrical conductor, wherein the elongate welded connections each extend in an irradiation direction from an irradiated region of the contact portion, or from an irradiated region of the electrical conductor in an opening in the contact portion, to a region of the contact portion which is opposite the irradiated region, so that the electrical conductor is connected to this region of the contact portion, wherein the irradiated regions are arranged in a grid pattern.
