Abstract: In an electrical plug connector having multiple metal contacts situated in parallel to each other for electrically contacting metal contact pins of a mating plug, a separate contact terminal is situated upstream from at least one of the contacts according to the invention, which electrically conductively contacts the at least one contact and is designed for being penetrated by a contact pin.

Abstract: A plug connector for direct electrical contacting of contact surfaces on a circuit board includes at least one electrical end contact of an electric line inserted into the plug connector housing in a plug-in direction and at least one separate electrical contact element, which protrudes elastically beyond one housing side of the plug connector housing transversely to the end contact for electrical contacting of a contact surface of the circuit board and is in electrically conductive contact with the end contact, at least when the contact surface has been contacted.

Abstract: In a direct contact plug-in connection having a circuit board, which has contact surfaces on its one side, and having a direct contact plug that is plug-connectible to the circuit board, which has contact elements for the electrical direct contacting of the contact surfaces of the circuit board, the contact surfaces are provided on a circuit board section that runs transversely to the plugging direction of the plug connection, the contact elements each contacting the contact surfaces, using their front end face, in the plugging direction.

Abstract: A contacting plug for contacting a contact carrier, in particular a circuit board, having two clamping claws able to be pivoted relative to each other, transversely to a plug-in direction, at least one of which is implemented as contact holder carrying at least one flexible contact element, which contact holder is implemented with a contact force for resting on the contact carrier, and a spring arrangement for generating a clamping force that is independent of the contact force. According to the invention, the spring arrangement is designed for bracing exclusively on the contacting plug for generating the clamping force.

Abstract: A plug connector position control element for checking the complete and proper execution of an electrical plug connection between a plug having a locking mechanism and a mating connector, which is constantly demonstrable at a remote location, as to whether the electrical plug connection is properly plugged in. A triggering element actuates a sensor element depending upon a properly executed plug connection.

Abstract: A plug part, in particular a cable harness plug, for producing an electrical plug connection to a further plug part, includes a housing, a contact carrier situated in the housing, as well as a gel or silicon multipole seal situated on the side facing away from the plugging direction. To enable the contacts situated in the contact carrier to be automatically inserted, it is provided that a flat surface is formed on the side facing away from the plugging direction, i.e., on the outgoing side of the cable, so that no interfering contour exists for the automatic insertion gripper. For this purpose, it is provided that a flat holding plate having insertion openings and being able to latch to the contact carrier is provided on the multipole seal, on the side of the plug part facing away from the plugging direction, locking arms hinged to and extending away from the holding plate being formed in the plugging direction of the plug part.

Abstract: As a rule, electrical microconnectors have a outer diameter of approximately 2 mm, the contact elements themselves having a dimension of approximately 0.63 mm. Described herein is a microconnector, which includes a housing and a plug connector situated in the housing. In addition, a primary and a secondary locking mechanism protect the microconnector against being unintentionally detached from a plug housing. The secondary locking mechanism acts on the end face of the microconnector facing in the direction opposite to the plugging direction. In order to now provide a greater contact area for the secondary locking mechanism, the end face is increased in size, in that the guide elements, which are necessary for inserting the microconnector in a directionally restricted manner and are provided on a side of the outer microconnector wall, extend to the end face of the microconnector, so that the end face of the guide elements and the end face of the microconnector form an enlarged surface.
