Abstract

An electrical connector, which may be a multi-pin connector, includes magnetic elements and mechanical alignment elements which provide connective forces and precision alignment and orientation. The magnetic elements permit a user to bring male and female connector portions only into “rough” alignment before magnetic forces bring the portions into the correct position. Pin contacts on the connector portions extend only a small amount beyond respective protective annular openings and are thereby protected. Spring-biased pin elements may be included on one of the connector portions to bias the contact pins into engagement and create conductive paths when the portions are in a connected position. Paramagnetic or non-magnetic sheaths may surround the magnetic elements to focus, or distribute, magnetic forces.

Claims

1. A connector assembly comprising:

a female connector including;

a seat body having a plurality of seat body annular openings formed therein;

a plurality of first conductive pins disposed within respective ones of the seat body annular openings, the conductive pins being biased in a forward direction by biasing elements;

at least one female connector magnet disposed within a recess formed in the seat body; and

at least one female connector alignment surface formed in the seat body; and

a male connector including;

a contact frame, including a plurality of contact frame annular openings formed therein;

a plurality of second conductive pins disposed within respective ones of the contact frame annular openings;

the conductive pins extending beyond a forward surface of the contact frame and adapted to engage respective ones of the first conductive pins and extend into the seat body annular openings;

at least one male connector magnet disposed within a recess formed in the contact frame, the male connector magnet cooperating with the female connector magnet to secure the male connector and the female connector in a connected position;

at least one male connector alignment surface formed on the seat body for cooperating with the at least one female connector alignment surface to align the male connector with the female connector when moved into a connected position; and

at least one sheath for at least partially enclosing one of the at least one male connector magnet or at least one female connector magnet.

2. The connector assembly of claim 1, wherein the at least one sheath is comprised of a non-magnetic material.

3. The connector assembly of claim 1, wherein the at least one sheath is comprised of a paramagnetic material.

4. The connector assembly of claim 1, wherein the female connector alignment surface comprises a pair of opposed ramp surfaces.

5. The connector assembly of claim 1, wherein the biasing elements comprise a spring and peg associated with each of the conductive pins, the pegs being secured in recesses formed in an adapter of the female connector.

6. The connector assembly of claim 1, wherein each of first conductive pins comprise pre-assembled, telescoping pins.

7. The connector assembly of claim 1, wherein the at least one male connector magnet includes a pair of magnets, each mounted on an opposite side of the male connector, and wherein the at least one female connector magnet includes a pair of magnets, each mounted on an opposite side of the female connector, the respective male and female connector magnets being of opposite polarity such that attractive forces are present when the male connector is properly oriented relative to the female connector, and repulsive forces are present when the male connector is improperly oriented relative to the female connector.

8. A connector comprising:

a contact frame, including a plurality of contact frame annular openings formed therein;

a plurality of conductive pins disposed within respective ones of the contact frame annular openings;

the conductive pins extending beyond a forward surface of the contact frame and adapted to engage respective ones of corresponding conductive pins on a counterpart connector;

a pair of connector magnets disposed within respective recesses formed in the contact frame;

a pair of sheaths, each at least partially enclosing a respective one of the connector magnets and distributing magnetic forces thereof;

a pair of alignment ramps formed on the seat body for cooperating with corresponding surfaces on the counterpart connector; and

a pair of alignment recesses formed on the seat body for receiving alignment projections formed on the counterpart connector.

9. The connector of claim 8, wherein each one of the pair of connector magnets is oriented with a polarity opposite the other.

10. The connector of claim 8, wherein the conductive pins comprise pre-assembled, telescoping, spring-biased pins.

11. The connector of claim 8, wherein the sheaths comprise a non-magnetic material.

12. The connector of claim 8, wherein the sheaths comprise a paramagnetic material.

13. A connector assembly comprising:

a female connector including;

a seat body having a plurality of seat body annular openings formed therein;

a plurality of first conductive pins disposed within respective ones of the seat body annular openings, the conductive pins being biased in a forward direction by biasing elements;

at least one female connector magnet disposed within a recess formed in the seat body; and

at least one female connector alignment surface formed in the seat body; and

a male connector including;

a contact frame, including a plurality of contact frame annular openings formed therein;

a plurality of second conductive pins disposed within respective ones of the contact frame annular openings;

the conductive pins extending beyond a forward surface of the contact frame and adapted to engage respective ones of the first conductive pins and extend into the seat body annular openings;

at least one male connector magnet disposed within a recess formed in the contact frame, the male connector magnet cooperating with the female connector magnet to secure the male connector and the female connector in a connected position;

at least one male connector alignment surface formed on the seat body for cooperating with the at least one female connector alignment surface to align the male connector with the female connector when moved into a connected position;

wherein the biasing elements comprise a spring and peg associated with each of the conductive pins, the pegs being secured in recesses formed in an adapter of the female connector.

14. The connector assembly of claim 13, wherein the at least one sheath is comprised of a non-magnetic material.

15. The connector assembly of claim 13, wherein the at least one sheath is comprised of a paramagnetic material.

16. The connector assembly of claim 13, wherein the female connector alignment surface comprises a pair of opposed ramp surfaces.

17. The connector assembly of claim 13, wherein each of first conductive pins comprise pre-assembled, telescoping pins.

18. The connector assembly of claim 13, wherein the at least one male connector magnet includes a pair of magnets, each mounted on an opposite side of the male connector, and wherein the at least one female connector magnet includes a pair of magnets, each mounted on an opposite side of the female connector, the respective male and female connector magnets being of opposite polarity such that attractive forces are present when the male connector is properly oriented relative to the female connector, and repulsive forces are present when the male connector is improperly oriented relative to the female connector.
