A contact casing (1) rolled from a spring plate blank with a rotary safety zone (30) is present for anchoring and centering of this winding contact in the contact hole of a plastic housing, which rotary safety zone has a centering section (40) encompassing the winding post (3) in the form of a ring and is connected firmly with it and has a clamping section (41). Lateral indentations (34a, 34b) act as spring elements by which the longitudinal seam (37) of the centering section (40) is held closed in the case of acting torques and radial forces. The clamping section (41) comprises clamping arms (42a, 42b) which are firmly connected by way of the base part (32) with the centering section (40) and the claws (44a, 44b) of which project beyond the periphery of the centering section (40). The firm connection of the clamping section (41) and the centering section (40) together with the always closed longitudinal seam (37) of the latter, will ensure that in the case of torques acting on the winding post (3), the claws (44a, 44b) will only be pressed more firmly into the contact hole wall, but the penetration depth will remain limited to the maximum value predetermined by the projection of the claws (44a, 44b) beyond the centering section (40). Thus, even in the case of housings made of a soft plastic, a reliable seat of the winding contact and a minimal damage of the contact holes are ensured. |
