Abstract: The present invention relates to an electrical plug connector assembly comprising a first connector (2), a second connector (29), a third connector (3) and a fourth connector (33). The first and the second connector (2, 29) form a first pair of connectors. The third and the fourth connector (3, 33) form a second pair of connectors. The first connector (2) and the third connector (3) are arranged on a housing (1). A locking element (7) is provided on the housing (1). The locking element (7) is configured as a slide and is displaceably mounted on the housing (1). In a starting position, the locking element (7) blocks at least partially an insertion opening (15) on the housing (1) for inserting the fourth connector (33) into the third connector (3). The second connector (29) has a guide bolt (30). The locking element (7) has guide surface (37, 52).

Abstract: The invention is embodied in a plug connector having first and second plug contacts, a conductive connecting member and a receiving element. The conductive connecting member is formed as a spring and is positioned between the first and second plug contacts to form an electrical contact between an inner surface of the first plug contact and an outer surface of the second plug contact. The receiving element houses the connecting member between the first and second plug contacts.
