Electrical adapter with fuse
View Patent ↗An electrical adapter is disclosed for providing overload protection between a conventional electrical receptacle and an external electrical plug comprising a housing comprising a plug housing portion and a receptacle housing portion. Electrical blades are supported to protrude from the plug housing portion for insertion within the conventional electrical receptacle. Electrical receptacles are supported within the receptacle housing portion for receiving an external conventional electrical plug. An over current fuse provides over current protection between the conventional electrical receptacle and the external electrical plug. The electrical adapter may include a thermal fuse to provide over heating protection between the conventional electrical receptacle and the external electrical plug.
1. An electrical adapter for providing current overload protection and over heating protection between a conventional electrical receptacle and an external electrical plug, comprising:
a housing having a plug housing portion and a receptacle housing portion;
a plurality of electrical blades supported by said plug housing portion to protrude from said plug housing portion for insertion within the conventional electrical receptacle;
a plurality of electrical receptacles supported within said housing for receiving an external conventional electrical plug;
an over current fuse interconnecting one of said plurality of electrical blades to one of said plurality of electrical receptacles for providing over current protection between the conventional electrical receptacle and the external electrical plug;
a thermal fuse located in thermal contact with at least one of said plurality electrical blades and said plurality electrical receptacles for terminating electrical conduction between the conventional electrical receptacle and the external electrical plug upon an over heated condition of the electrical adapter;
said over current fuse is connected between one of said plurality electrical blades and one of said plurality of electrical receptacles; and
said thermal fuse being connected between the other of said plurality electrical blades and the other of said plurality of electrical receptacles.
2. An electrical adapter for providing current overload protection and over heating protection between a conventional electrical receptacle and an external electrical plug, comprising:
a housing having a plug housing portion and a receptacle housing portion;
a plurality of electrical blades supported by said plug housing portion to protrude from said plug housing portion for insertion within the conventional electrical receptacle;
a plurality of electrical receptacles supported within said housing for receiving an external conventional electrical plug;
an over current fuse interconnecting one of said plurality of electrical blades to one of said plurality of electrical receptacles for providing over current protection between the conventional electrical receptacle and the external electrical plug;
a thermal fuse located in thermal contact with at least one of said plurality electrical blades and said plurality electrical receptacles for terminating electrical conduction between the conventional electrical receptacle and the external electrical plug upon an over heated condition of the electrical adapter; and
said thermal fuse is connected in series with said over current fuse between one of said plurality electrical blades and one of said plurality of electrical receptacles.
3. An electrical adapter as set forth in claim 2 , wherein said plug housing portion is secured to said receptacle housing portion for enclosing said over current fuse.
4. An electrical adapter as set forth in claim 2 , wherein said plug housing portion is permanently secured to said receptacle housing portion for enclosing said over current fuse.
5. An electrical adapter as set forth in claim 2 , wherein said plug housing portion includes a plurality of blade apertures for enabling said plurality of electrical blades to extend therethrough; and
a receptacles housing portion having a plurality of blade supports extending from said receptacles housing portion for retaining said plurality of electrical blades within said plurality of blade apertures of said plug housing portion.
6. An electrical adapter as set forth in claim 2 , including an illuminator for indicating electrical conduction of the electrical adapter between the conventional electrical receptacle and the external electrical plug.
7. An electrical adapter as set forth in claim 2 ,
wherein said over current fuse includes a first and a second terminal; and
said first and second terminals of said over current fuse interconnecting one of said plurality of electrical blades to one of said plurality of electrical receptacles for providing over current protection between the conventional electrical receptacle and the external electrical plug.
8. An electrical adapter as set forth in claim 2 ,
wherein said thermal fuse includes a first and a second terminal; and
said first and second terminals of said thermal fuse interconnecting one of said plurality of electrical blades to one of said plurality of electrical receptacles for providing thermal protection between the conventional electrical receptacle and the external electrical plug.
