Plug-in connector

Plug-in connector (1) comprising:

• an enclosure (2) of insulating material,
• at least one conductor entry opening (3), open toward a conductor connection side of the plug-in connector (1), which in each case leads into an associated conductor connection space (4) in the enclosure (2) of insulating material for electrically conductively connecting an electric conductor (4) introduced into a conductor entry opening (3),
• in each case one clamping spring element (6) arranged in the conductor connection space (4), which element has a supporting leg (9) for localizing the clamping spring element (6), and a clamping leg (7) for clamping an electric conductor (5),
• at least one contact pin receiving opening (8), leading into in each case one associated conductor connection space (4) and open toward a contact pin connection side (13) different from the conductor connection side, for introducing contact pins (14), and
• in each case one one- or multi-part busbar element (10) in the conductor connection space (4) which is constructed for forming a clamping point for an associated electric conductor (5) in such a manner that an electric conductor (5) introduced into a conductor entry opening (3) is pressed against the busbar element (10) by the clamping leg (7) of the clamping spring element (6),
• characterized in that
• at least one part of the busbar element (10) is in each case arranged in the boundary area between an associated conductor entry opening (3) and an associated contact pin receiving opening (8) in such a manner that the part of the busbar element (10) is located between a contact pin (14) and an electric conductor (5) and electrically conductively rests against the contact pin (14) and the electric conductor (5) and
• the busbar element (10) has a resilent contact area in the contact pin receiving opening (8) for electrically contacting the busbar element (10) by a spring force with a contact pin (14) which can be introduced into an associated contact pin receiving opening (8).
