Abstract: A plug connector set-up for a control unit includes: a pin support having a pin; and a guide element having a lead-through for positioning the pin at a circuit board of the control unit. The lead-through has an entrance opening on the side facing the pin support and an outlet opening on the side facing away from the pin support. A diameter of the entrance opening is greater than a diameter of the outlet opening. The pin includes a centering region having a diameter which is less than the diameter of the entrance opening and greater than the diameter of the outlet opening.

Abstract: A tool (10) is disclosed for fine machining of optically active surfaces (F), with a base body (12) that can be attached to a tool spindle of a machine tool, and an elastic membrane (14) that has a machining section (16) to which connects a gaiter section (18) by means of which the membrane is attached to the base body such that it can be rotated therewith. The base body and the membrane delimit a pressure medium chamber (20) which via a channel (22) can be optionally pressurized with a pressure medium in order to apply a machining pressure via the machining section during machining of the optically active surface. A guide element (24) guided longitudinally mobile on the base body is actively connected with the machining section so that the machining section can be moved in the longitudinal direction of the guide element and held in the transverse direction to the guide element, although under an elastic deformation of the gaiter section it is tilt-mobile in relation to the guide element.
