Plug connector for a light conductor utilizing two-point contact

摘要

A plug connector for a light conductor includes a plug pin having a longitudinal pin axis connected to the end of the light conductor so as to be coaxially therewith. A plug housing has a receiving bore formed therein for receiving the plug pin therein. A fixing arrangement fixes the plug pin in position in the receiving bore. This fixing arrangement includes two longitudinal grooves formed in the wall of the receiving bore so as to be disposed one behind the other and spaced a predetermined distance from each other. Two press pins are movably mounted in the housing so as to lie opposite the approximate centers of corresponding ones of the grooves. A latching member mounted on the housing is movable between first and second positions. The latching member and the housing conjointly define a space for accommodating an intermediate piece directly above the two press pins. An abutment structure is provided for imparting a force to the intermediate piece when the latching member is moved into its second position so as to cause the intermediate piece to engage and press the press pins against the plug pin thereby clamping the latter against the grooves to fix the plug pin in position in the receiving bore. The plug connection provides a very good reproducibility of the fixation of the axis of the light conductor. In addition, the plug connector ensures a permanent constancy of the axis of the conductor even when the light conductor is mechanically stressed externally of the plug connector.
