Abstract: A modular jack applicable to a flat assembly. A hole is pierced in a flat member and a cover that can be opened and closed is disposed so as to cover an opening of the hole. When a modular plug is inserted into the hole, the cover is opened; when not, the cover is closed. When the cover is closed, it is housed in the opening, and the modular jack equals the flat member substantially in thickness. When the modular plug is inserted into the hole through the opening with the cover open, the insertion direction of the modular plug is regulated by inner walls of the hole. When the tip of the modular plug abuts against a bottom portion of the hole, the modular plug cannot be inserted any more. In the state, an electrode section located in the hole is electrically connected to electrodes of the modular plug. A hook portion disposed in the cover locks the modular plug so as to prevent the modular plug from easily dropping out of the modular jack even if the modular plug is pulled.

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).

Abstract: The electric junction box of this invention has a plurality of connector receiving sockets mounted on its insulating box. Selected one of the connector receiving sockets, or the first connector receiving socket, is attached with a locking cover, which is urged by a spring to lie flat over the adjacent or second connector receiving socket. A first connector can be assembled onto the first socket but a second connector cannot be connected to the second socket unless the locking cover is erected and locked onto the first connector. To rule out the slightest possibility of erroneous connection sequence, a connection sequence check member is provided to the second connector.
