Abstract
Abstract A dust cover and locking assembly (10) is mounted ajdacent to a fixed electrical or fiber optic receptacle connector (18) without modification thereto. A spring loaded cover member (46) has a sealing surface (54) which is moved into engagement with an exposed end (28) of the fixed connector (18) when a mating plug connector (34) is disconnected therefrom. The sealing surface (54) sealingly engages with a side wall (38) of the mating connector (34) when it is connected to the fixed connector (18), thereby preventing contamination of the sealing surface (54) by air or dust. Frictional engagement, latching, or cam action between the cover member (46) and mating connector (34) prevents the latter from being unintentionally loosened from the fixed connector (18).
