Abstract: An interlocking mechanism designed to have an increased locking force, which can simultaneously be actuated by a small force. To this end, an electric connector, which includes a coupling part and a plug part, has a locking element that has a bending arm pointing away from the plug part, and a lever arm running transversely to the bending arm. A stop element is positioned on the side of the bending arm that faces the coupling part in the plugged-in state, the stop element being designed in such a manner that the movement of the bending arm is restricted in the direction of stop element, and that the bending arm can swing horizontally away from the stop element.

Abstract: An electric plug-and-socket device having a fixation device and having a closed position of the plug-and-socket device that is discernable readily from the outside and is securable. The plug-and-socket device, which is composed of a first plug connector and a second plug connector which can be joined to it, is provided with a control slide mounted on the first plug connector as part of the fixation device. This control slide is convertable from an unlocked position in which it assumes a first position with respect to a mark to a locked position in which it assumes a second position with respect to the mark only when the two plug connectors have been joined completely. The closed position of the plug-and-socket device is discernable readily by the second position of the control slide with respect to the mark and is additionally securable by the control slide.

Abstract: A plug connection having a first connector, which can be sealingly coupled to a second connector, is designed such that contact elements of the first connector are secured axially and the unit volume of the plug connection is small. The first connector has contact elements , which, in an end area that is facing the second connector, support locking bodies, which can be overlapped axially in a form-locking manner by a locking element that is movably supported on the first connector. A seal that generates the seal between the two connectors is mounted in the locking element axially downstream and therefore in the spatial vicinity of the end area, as a result of which a pot-shaped plug-in receptacle of the second connector that overlaps the seal is of small axial dimensions. The locking element, if not correctly inserted may block mating of the first and second connectors. This plug connection may advantageously be used in motor vehicles in cramped installation circumstances.

Abstract: An electrical plug-in connector includes a plug part and a socket part providing an electrical connection for a cable having a plurality of core leads. The plug-in connector includes a locking element. The locking element includes a locking clamp arranged on the plug part. The locking part cooperates with a locking element that is arranged on the socket part. In the plugged-in state of the plug-in connector, the locking clamp cooperates with a locking element that is arranged on the socket part. The socket part includes a protective housing which, in the plugged-in state, surrounds the locking clamp in a U-shaped fashion so that the locking clamp is arranged within the protective housing.

Abstract: A multi-plug electrical connector includes an interlocking element. The connector is coupled to a mating connector, such that the interlocking forces of the interlocking element are independent of the unlocking forces of the interlocking element when the connector is released from the mating connector. For this purpose, the interlocking element is actuated to interlock and, to release the interlocking arrangement in directions that differ from one another. Flexural regions and walls, as well as webs of the interlocking element are resiliently deformed. The connector is preferably used in automobile manufacturing under conditions of high stress due to shaking.

Abstract: An electrical plug connector for electrically connecting and mechanically interlocking with a mating connector, including a connector housing having an outer support member. The outer support member is positioned substantially in the middle of the connector housing. The plug connector also includes a snap-on surface and a snap-fit device which is pre-molded to the connector housing. The snap-fit device includes a U-shaped bending bar which has a first limb and a second limb. The first limb is secured to the outer support member with a first connecting end and the second limb includes an unattached end and an orifice. The orifice is positioned substantially at the unattached end for engaging with a snap-on surface of the mating connector when the electrical plug connector is inserted into an opening of the mating connector. The plug connector is intended for use in electronic control instruments in motor vehicles.

Abstract: The locking lever of a detachable electrical plug connection can be produced cost-effectively and makes it possible to lock the plug connection securely. The locking lever is manufactured completely from a sheet-metal part, first guide elements, by means of which the locking lever is mounted on a plug housing such that it can rotate, being produced on the one hand, and second guide elements, by means of which the locking lever engages in guide tracks of a plug receptacle, being produced, for example via a deep-drawing or thermoforming process on the other hand. For functionally secure guidance of the locking lever, the first guide elements preferably have stamped projections as an axial withdrawal protection device, which secure the position of the locking lever even when forces are applied in this position which are directed transversely with respect to the pivoting direction. The locking lever is preferably used in the case of multipole elongated electrical plug connections.
