Plug connector for a light conductor utilizing two-point contact

A plug connector for a light conductor having a longitudinal axis, the plug connector comprising:

• a plug pin having a longitudinal pin axis connected to the end of the light conductor so as to be coaxial therewith;
• a plug housing having a receiving bore formed therein for receiving said plug pin therein, said bore defining a longitudinal axis, and,
• fixing means for fixing said plug pin in position in said receiving bore, said fixing means including:
• first and second support means formed on the wall of said receiving bore so as to be disposed one behind the other in the direction of said axis and spaced a predetermined distance from each other;
• two press pieces movably mounted in said housing so as to lie opposite corresponding ones of said first and second support means, said two press pieces having respective end faces facing away from said grooves;
• a latching member mounted on said housing so as to be movable between first and second positions in the direction of said pin axis, said latching member and said housing conjointly defining a space at the region of said press pieces;
• an intermediate piece movably mounted in said space between said housing and said latching member so as to be movable toward and away from said end faces of said press pieces;
• abutment means for imparting a force to said intermediate piece when said latching member is moved into said second position so as to cause said intermediate piece to engage and press said press pieces against said plug pin thereby clamping the latter against said first and second support means, respectively, to fix said plug pin in position in said receiving bore;
• and,
• gap means formed in said wall between said first and second support means so as to cause said plug pin to be braced against only said first and second support means when said press pieces are pressed against said plug pin by said intermediate piece.
