Multichannel optical coupling configuration

A multichannel optical coupling configuration, comprising:

• a plug-in connector having a housing;
• a multichannel optical fiber end piece configured in an axially resilient manner in said housing of said plug-in connector;
• a circuit board;
• a coupling partner configured on said circuit board, said coupling partner having a plug-in inlet for accommodating said housing of said plug-in connector in order to make a plug-in connection with said plug-in connector, said coupling partner defining a plug-in direction, said plug-in-inlet formed with a recess;
• a housing wall formed with a recess;
• a holder for being configured in said recess in said housing wall, said holder for guiding and retaining said plug-in connector and for guiding said coupling partner, said holder including an outer housing configured to be displaceable at right angles to the plug-in direction, said holder including an inner housing configured pivotably in said outer housing;
• a locking element designed as a lever having two arms, said locking element configured on said inner housing of said holder, said locking element for retaining said plug-in connector in said holder;
• and
• a spring acting on one of said two arms of said locking element;
• said housing of said plug-in connector including at least one resilient latching arm with a latching lug that can be accommodated in said recess of said plug-in-inlet in order to latch said plug-in connector to said coupling partner;
• said plug-in inlet of said coupling partner having finger-like guide elements extending in the plug-in direction, said guide elements having operative faces configured in a stepped manner;
• said inner housing of said holder having guide faces cooperating with said guide elements for coupling said coupling partner in an accurately fitting manner to said plug-in connector;
• said one of said two arms of said locking element having operative faces for unlocking said locking element;
• and
• said recess of said plug-in inlet and said operative faces on said guide elements of said plug-in inlet being staggered in the plug-in direction such that when said coupling partner is joined to said plug-in connector retained in said holder, said locking element that is retained in said holder is unlocked after said latching lug of said plug-in connector has latched in said recess in said plug-in inlet.
