Abstract
The safety interlock for a cover of a housing in a telephone apparatus provides electrical safety for the user by requiring the apparatus to be disconnected from a telephone line before the cover of the housing can be opened. The apparatus is connected to the telephone line by means of a two-part pluggable connector, with one of the parts being a receptacle fixed in the case of the apparatus. The safety interlock comprises a flap (8) which slides inside the case (1, 2) of the apparatus over the opening (5) giving access to the telephone line connector receptacle, with the flap sliding between a closed position in which it disengages the opening (5) while holding the cover (8) of the housing closed, and an open position in which it obstructs the opening (5) while allowing the cover (3) of the housing to be opened.
