Abstract
Claims
[1] Arrangement (1) with an elongated metal part (3), wherein a further metal part (2) is provided and the two metal parts (2, 3) are connected by means of a crimp connection, wherein the crimp connection has crimp wings (5) between which the elongated metal part (3) is arranged and, after forming the crimp wings (5), is permanently fixed to the further metal part (2) and electrically contacted, characterized by that the elongated metal part (3) has in its end region, with which it is inserted and fastened in a crimp connection region of the further metal part (2), a slot (6), in particular a longitudinal slot (6), into which the ends of the crimp wings (5) dip after the forming. [2] Arrangement according to claim 1, characterized by that the elongated metal part (3) is an end region of an electrical conductor, in particular a stamped grid, and the further metal part (2) is a contact element. [3] Arrangement according to claim 1 or 2, characterized by that the cross-section of the slot (6) is trapezoidal. [4] Arrangement according to one of the preceding claims, characterized by that the depth of the slot (6) is approximately 1 / 3 to half the height of the elongated metal part (3), in particular of the electrical conductor (3). [5] Arrangement according to one of the preceding claims, characterized by that the width of the elongated metal part (3) is approximately 0.8 mm to 1 mm, the width at the base of the slot (6) being 0.05 mm to 0.08 mm.
