Abstract

A signal carrying plug and a signal carrying receptacle form a magnetic signal carrying connector are provided wherein electrical terminals of the source and electrical contacts of the load are held against one another by at least one magnet affixed adjacent the source terminals confronting and attracted to magnetically interactive object affixed adjacent the load contacts, and wherein the at least one magnet is disposed within a recess to protect against projection of unwanted magnetic fields and to mate with a complementary structure to provide positive alignment and registration of the terminals and contacts. The force of the magnet is sufficient to hold the load contacts in place for operation but insufficient to provoke damage to the connector plug or attached receptacle and any attached structures, such as cabling, if the connector is pulled apart. the magnets serve as signal carrying terminals.

Claims

1. A signal-carrying receptacle for receiving a complementary plug comprising:

a housing with a first face;

a set of electrical terminals for carrying signals, said terminals being disposed along a circumference on said first face,

a magnet of a first polarity on said first face for engaging a second opposing face in the complementary plug; and

a structure for receiving and aligning the complementary plug with said first face such that electrical contacts of the complementary plug aligns at least axially with said electrical terminals,

wherein said magnet is operative to mate with a specific magnetically attractable element of the complementary plug with sufficient force to maintain reliable electrical connection between said terminals and contacts and not so much force as to result in physical damage upon withdrawal of the plug from said receptacle.

2. The receptacle according to claim 1 wherein said magnet comprises at least one of the electrical terminals, and said magnets are arranged to complement, align and attract said electrical contacts.

3. The receptacle according to claim 1 wherein said aligning and receiving structure comprises at least three magnets mounted on said first face disposed along said circumference, with two of said at least three magnets having a common polarity and being operative to confront magnets arranged in a complementary and opposing polarity pattern on the complementary plug.

4. The receptacle according to claim 3 wherein said magnets are electrical terminals for carrying signals.

5. The receptacle according to claim 1 wherein said aligning and receiving structure is a recess forming a keyway to mate a key shape of the plug for physically orienting the plug to align terminals and contacts.

6. The receptacle according to claim 1 further including a conventional contact phone receptacle, said conventional contact phone receptacle being in said first face.

7. The receptacle according to claim 1 further including a conventional contact phone receptacle, said conventional contact phone receptacle being mounted in the same housing as said terminals and being in electrical contact with said terminals.

8. The receptacle according to claim 7 further including a conventional contact phone plug coupled to the terminals, said conventional contact phone plug being in a position to be inserted into a conventional phone receptacle thereby to define an adapter.

9. The receptacle according to claim 1 further including a conventional contact phone plug coupled to said terminals, said conventional contact phone plug being in a position to be inserted into a conventional phone receptacle thereby to define an adapter.

10. The receptacle according to claim 1 adapted to be mounted in an armrest.

11. A signal-carrying plug for insertion into a complementary signal-carrying receptacle comprising:

a housing with a second face;

electrical contacts for carrying signals, said contacts being disposed along a circumference on said second face,

a magnetically attractable structure on second for mating with a magnet on said first face for engaging a second opposing face in the complementary plug; and

a structure for inserting into and aligning the complementary receptacle with said second face such that electrical contacts of the complementary receptacle align at least axially with said electrical contacts;

wherein said magnetically attractable structure is drawn by the magnet with sufficient force to maintain reliable electrical connection between said contacts and terminals and not so much force as to result in physical damage upon withdrawal of said plug from the magnetic receptacle.

12. The plug according to claim 11 wherein said inserting and aligning structure is a key matched to a recess keyway of a mating shape of the receptacle for physically orienting the plug to align terminals and contacts.

13. The plug according to claim 11 wherein said inserting and aligning structure comprises at least three magnets mounted on said second face disposed along said circumference, with two of said at least three magnets having a common polarity and being operative to confront magnets arranged in a complementary and opposing polarity pattern on the complementary receptacle.

14. The plug according to claim 13 wherein said magnets are electrical contacts for carrying signals.

15. The plug according to claim 11 wherein said magnetically attractable structure is an electrical terminal for carrying signals.

16. The plug according to claim 14 further including a conventional contact phone receptacle, thereby to form an adapter.

17. The plug according to claim 11 further including a conventional contact phone receptacle, thereby to form an adapter.
