Patent ID: 8292677

Claim:
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 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 resilient 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 ).
