Plug connector for printed circuits

A plug connector for a ribbon cable with multiple conductors having a contact portion composed of first conductor portions, said connector having a plug, which at least partly surrounds the ribbon cable and leaves the contact portion free, and having a socket with contact points, into which the plug can be introduced as far as a predetermined contact position, in which the contact points of the socket and the contact portion are in electrically conductive communication, characterized in that the plug (10) braces the contact portion (42) of the ribbon cable (40) on one side and clamps the ribbon cable in place in an axially fixed manner;

• that a retaining element is provided between said socket (20) and said plug (10), with which the plug (10) is pre-lockable in the socket (20) in a manner to transfer axial tension exerted on the cable (40) to the socket (20) via said retaining element once said plug has reached a defined axial detent position (R) in the socket (20);
• and that once this axial detent position (R) is exceeded, the contact portion (42) or the contact points, with a vertical component of motion, reach said predetermined contact position (K), in which the plug (10) is lockable in a final state to the socket (20) by means of a locking element.
