Abstract
Three terminal prongs are anchored in the base (1) of the apparatus plug. For a bipolar fuse protection thereof two safety fuse cartridges (10) are located in a fuse carrier (8) in a separate adjacent base compartment (7) into which fuse carrier (8) can be inserted and be withdrawn and which opens over the upper side of the base and has a selected depth for a minimal mounting depth. The bottom cap (12) of the safety fuse cartridge rests against a bottom contact terminal (14) located fixed at the bottom of the base compartment with a connecting lug (15) extending towards the outside of the base and electrically connected with a connecting lug of one terminal prong (4). The top cap (13) of the safety fuse cartridge is embraced by a contact hood (23) guided for movement against the action of a spring (24) and carries a contact tongue (22) projecting from the edge of the contact hood which upon inserting of the fuse carrier into the separate socket compartment (7) is slid betwen a leaf spring pair (20) mounted fixedly to the compartment inner wall. By means of such, an electrical connection is established from the connecting lug of the leaf spring pair extending towards the outside via…
