Abstract: An electrical plug and socket connector, having a socket part and a plug part, is described, the socket part including a housing, in which an actuating lever is mounted so that it can pivot about a pivot point. The lever includes teeth at its free end, which work together with an additional gearing element, which is connected to a plug connector that is displaceable in the housing almost perpendicularly to the direction of insertion via guide grooves. The teeth of actuating lever are arranged on an elliptical path with respect to pivot point of actuating lever, and gearing element is arranged obliquely to the actual direction of displacement of plug connector.

Abstract: A fastening device for a plug connector part of an electric plug connection including receptacle chambers for assembly with contact elements and a slide that facilitates the application of joining and separating forces of the electric plug connection are provided in a contact carrier on the plug connector part. The fastening device, which may be a retention clamp, can be secured by a catch connection to a casing of the plug connector part. The fastening device brings switch elements of the plug connector part out of a position in which they overlap with respective receptacle chambers and secures the slide in an open position for subsequent coupling with a mating connector. When the plug connector part is delivered to an assembly plant, all the receptacle chambers can be assembled directly with contact elements and the plug connector part can be coupled with the mating connector by removing the fastening device.

Abstract: A four-pole electric connector is designed so that the contact elements can be easily locked to their axial fastening. The connector has a slide for coupling with a mating connector, which slide can be inserted in receptacles of a contact carrier of the connector transversally to the direction of insertion of contact elements and moved longitudinally. The slide contains a seat for a locking element, which is provided for axially securing the contact elements. The locking element is brought together and joined with the contact elements through an insertion motion of the slide until a closing position is reached, where the locking element engages with the contact carrier. When the slide is moved in the opposite direction to an open position, the locking element is removed from the seat in a similar manner, while it remains on the contact carrier and the contact elements.

Abstract: The invention relates to a fuel injection pump for internal combustion engines with a pump plunger (18), a drive shaft (11) for the actuation of the pump plunger (18) and a rotational-angle sensor (30) for detecting the angular position of the drive shaft (11), the pulse generator of which is designed as a generator wheel (32) seated firmly in terms of rotation on the drive shaft (11) and the pulse pick-up (31) of which is held on a carrier ring (35) seated rotatably on the drive shaft (11). For the purpose of narrowly toleranced exact association of the pulse generator wheel (32) and the pulse pick-up (31) both in the radial and in the axial direction, the pulse pick-up (31) is accommodated in a sensor housing (40) and this housing is fixed positively and frictionally on the carrier ring (35) by means of plug-in elements.
