Abstract

An electrical connector for a kitchen appliance includes a socket having at least one electrical contact and at least one metallic member. A plug having at least one electrical contact and a magnet which is movably positioned within the plug. A power cord is movably positioned within the plug and is operatively connected to the at least one electrical contact of the plug. An attractive force exists between the at least one metallic member and the magnet when the plug is engaged with the socket and the magnet is within a predetermined distance of the at least one metallic member. Movement of a leading end of the power cord toward a distal end of the plug moves the magnet toward the distal end of the plug to reduce a magnitude of the attractive force and permit the plug to be more easily removed from the socket.

Claims

1. An electrical connector for a kitchen appliance, the connector comprising:

a socket mounted to the kitchen appliance, the socket having at least one electrical contact and at least one metallic member;

a plug having a proximal end and an opposite distal end, the proximal end of the plug having at least one electrical contact for operative engagement with the at least one electrical contact of the socket;

a magnet movably positioned within the plug, the magnet having a first end and an opposite second end; and

a power cord having a leading end and an opposite trailing end, the leading end being movable with respect to the plug and being operatively connected to the magnet and the at least one electrical contact of the plug, the trailing end being operatively engageable with an electrical outlet,

wherein an attractive force exists between the at least one metallic member and the magnet when the plug is engaged with the socket and the magnet is within a predetermined distance of the at least one metallic member, and wherein movement of the leading end of the power cord away from the proximal end of the plug moves the magnet toward the distal end of the plug to reduce a magnitude of the attractive force and permit the plug to be more easily removed from the socket.

2. The electrical connector according to claim 1, wherein the magnet is slidable with respect to the proximal and distal ends of the plug.

3. The electrical connector according to claim 2, further including at least one linking member movably mounted within the plug, wherein at least a portion of the at least one linking member is fixedly attached to at least a portion of the magnet.

4. The electrical connector according to claim 3, wherein at least a portion of the at least one linking member is connected to at least a portion of the magnet.

5. The electrical connector according to claim 4, wherein the power cord is fixedly attached to at least a portion of the at least one linking member.

6. The electrical connector according to claim 5, wherein the distal end of the plug includes an opening and wherein at least a portion of the at least one linking member is movably positioned within the opening.

7. The electrical connector according to claim 3, wherein the at least one linking member surrounds at least a portion of the magnet.

8. The electrical connector according to claim 4, wherein the at least one linking member includes a receptacle sized and shaped to receive at least a portion of a flange of the magnet.

9. The electrical connector according to claim 1, wherein the proximal end of the plug includes at least one metallic plate, wherein at least a portion of the at least one plate extends outwardly beyond the proximal end of the plug.

10. The electrical connector according to claim 9, wherein the magnet is movable between a first position in which at least the first end of the magnet is adjacent the at least one plate and a second position in which the first end of the magnet is spaced a predetermined distance from the at least one plate.

11. The electrical connector according to claim 9, wherein the proximal end of the plug includes two spaced-apart metallic plates, at least a portion of each plate extending outwardly beyond the proximal end of the plug.

12. The electrical connector according to claim 11, wherein the two plates are fixedly mounted within the plug.

13. The electrical connector according to claim 11, wherein the proximal end of the plug includes two spaced-apart electrical contacts and the socket includes two spaced-apart electrical contacts, each electrical contact of the plug being sized and shaped to engage at least a portion of one of the electrical contacts of the socket.

14. The electrical connector according to claim 13, wherein the two metallic plates are located between the two-spaced apart electrical contacts of the plug.

15. The electrical connector according to claim 1, wherein the kitchen appliance is a deep fryer.

16. The electrical connector according to claim 1, further comprising:

a flexible electrical lead operatively connecting the leading end of the power cord to each of the electrical contacts within the plug.
