Abstract: The invention relates to a method for producing a proximity switch, in which the molding of the electronic components with a plastic compound results in a molded body whose external dimensions correspond to the internal dimensions of a housing and the molded part is inserted into the housing and connected with it. To reduce production tolerances it is proposed that, before the molding with the plastic compound, a sensor head and a switching plate are connected mechanically to one another, so that they can move with respect to one another, by means of essentially flexible electric lines, that these two parts are inserted into an injection casting form, that they are held or brought there by means of fixer elements in a firm, predetermined position to one another and to the wall of the injection casting form, and that they are molded in this fixed position.

Abstract: An electrical plug-and-socket connection with a male plug that includes at least two contact pins, which contact pins are linked to a base body of a plug-in aperture for a plug-in section of a female plug, and after connection of the male and female plugs are inserted into contact apertures of the front side of the plug-in section, and where the section of every contact pin that connects immediately to the base body of the plug-in aperture is circumferentially insulated by a collar that is connected by being of identical material with the base body. To increase the high-voltage-proof quality in plug-and-socket connections with contact pins placed close together, the invention proposes that the rounded conical-shaped mantle surface of the collar when the plug parts are connected is in uninterrupted circumferential contact with a section of the walling of the contact aperture, at least in some areas.

Abstract: A connector element of an electrical plug-in connection with a contact carrier (1) has one or more electrical contacts, and a w screw sleeve (2) which is rotatably associated with the contact carrier (1). A radially protruding thread engagement projection (3) enters into a fastening thread (4) of a mating connector element (5). The thread engagement projection (3) is associated with the screw sleeve (2) in such a way that it can yield elastically in the radial direction such that, after sliding over the thread ribs (4?) of the fastening thread (4), it can be driven by a drive bevel (6, 10) of the connector element into the thread groove (4?).
