Abstract
The present invention relates to a plug with an integral fuse which is to be inserted into a conventional outlet of a power supply, e.g., an A.C. outlet having openings to accept the two plug's two terminals. It has heretofore been known to provide plugs of this type with a fuse connected in series with one of the lead wires and the corresponding plug terminal which is to be inserted into the outlet. Such fused plugs usually comprise a housing with a replaceable cartridge type fuse therein which is held between a generally U-shaped pair of spring contacts. The housing can be opened to replace the fuse if it blows.
