Optical waveguide connector assembly

A connector assembly, comprising:

• a connector;
• an optical waveguide;
• a circuit board having at least one first through-hole and a transmitter/receiver configured to transmit and/or receive light signals, the connector being interlockingly and releasably connected to the circuit board via at least one fastening element which is passed through the first through-hole and connected to the circuit board, the connector having a first receiving chamber which at least partially borders the transmitter/receiver;
• a lens unit disposed in the first receiving chamber that light-conductively connects the transmitter/receiver to the optical waveguide;
• and
• a locking element movably disposed on the connector, the locking element being disposed at least partially within the first receiving chamber and securing the lens unit in the first receiving chamber, and the locking element being movable into a final latched position in which the locking element extends at least partially into the first through-hole and blocks release of the at least one fastening element from the circuit board.
