An electrical connector ( 100 ) comprising a male ( 120 ) and female ( 150 ) part, each part ( 120, 150 ) having a magnet ( 135, 165 ) adapted to attract the parts ( 120, 150 ) together to make a connection. The parts ( 120, 150 ) can connect at any relative rotational orientation and preferred embodiments prevent offset connection between the magnets ( 135, 165 ) or parts ( 120, 150 ). The connector ( 100 ) is particularly suited for use in out of reach locations, for example to easily and safely replace light bulbs into sockets suspended from a ceiling.
1. An electrical connector comprising a male part and a female part for engagement therewith; the male part comprising a first terminal having a circular cross section and a second terminal; the female part comprising engaging means to engage said terminals; wherein the male and female parts each comprise a magnetic portion adapted to magnetically attract the parts together to form an electrical connection; magnetic misconnection means are provided that prevent the male and female parts from magnetic attachment in a non-concentric position; wherein at least some of a magnetic field emitted from at least one of the magnetic portions extends beyond the magnetic misconnection means to attract the parts together to form an electrical connection.
2. A connector as claimed in claim 1 , wherein the magnetic misconnection means comprises a wall extending away from the magnetic portion of one of the male and female parts, the wall being adapted to prevent the male and female parts from connecting in a non-concentric position.
3. A connector as claimed in claim 2 , wherein at least one of the male and female parts is attached to pendent means.
4. A connector as claimed in claim 3 , wherein one of the male and female parts is attached to pendent means and the other of the male and female parts comprises the wall.
5. A connector as claimed in claim 1 , wherein the female part has a projecting portion which is adapted to be received within the male part.
6. A connector as claimed in claim 5 , wherein the magnetic portion of the female part has a magnetic field which extends beyond the projecting portion to attract the parts together to form an electrical connection.
7. A connector as claimed claim 5 , wherein the projecting portion is adapted to have a degree of freedom to pivot within the male part.
8. A connector as claimed in claim 5 , wherein the projecting portion has at least one aperture to receive at least one of the male terminals.
9. A connector as claimed in claim 1 , wherein the first terminal is a neutral terminal and the second terminal is a live terminal and the engaging means of the female part comprise respective neutral and live terminals.
10. A connector as claimed claim 9 , wherein the neutral and live terminals of the female part are enclosed.
11. A connector as claimed in claim 9 , wherein the neutral and live terminals of at least one of the male and female parts are resilient.
12. A connector as claimed in claim 9 , wherein the male and female parts each include an earth terminal which are adapted to engage with each other.
13. A connector as claimed in claim 12 , wherein the male earth terminal is concentric with at least one of the first and second terminals of the male part.
14. A connector as claimed in claim 12 , wherein the terminals are adapted to engage in the order: earth, then neutral, then live when the male and female parts are being connected and are adapted to disengage in the order: live, then neutral, then earth when said parts are being disconnected.
15. A connector as, claimed in claim 1 , wherein the magnetic portions have a circular cross section.
16. A connector as claimed in claim 15 , wherein the magnetic portions are in the form of an annular ring.
17. A connector as claimed in claim 1 , wherein one of the male and female parts is also adapted for use with any type of electrical appliance.
18. A connector as claimed in claim 1 , wherein the male and female parts are adapted to be attracted together to form an electrical connection when they are between 1 cm and 30 cm apart.
19. A connector as claimed in claim 1 , wherein the male and female parts are adapted to be attracted together to form an electrical connection when they are between 2 cm and 30 cm apart.
20. A connector as claimed in claim 1 , wherein the male and female parts are adapted to be attracted together to form an electrical connection when they are at between 5 cm and 30 cm apart.
21. A connector as claimed in claim 1 , wherein at least one of the parts comprises a tapered face adapted to guide the parts together.
22. A connector as claimed in claim 1 , wherein the first and second terminals are concentric.
23. A connector as claimed in claim 1 , wherein the male and female parts are adapted to engage with each other in any relative rotational orientation.
