Abstract

A plug (1) for electrical equipment comprising a housing and a plurality of projections (2, 4, 5) extending from the housing, wherein first and second projections are larger than a third projection, and the projections are arranged so as to facilitate disengagement of the plug from the socket.

Claims

1. A plug for electrical equipment comprising a housing and a plurality of projections extending from the housing for receipt by a socket and for electrical connection therewith, wherein first and second projections are longer than a third projection, wherein the projections are arranged to facilitate disengagement of the plug from a socket.

2. The plug of claim 1, wherein the third projection is substantially shorter than the first and second projections.

3. The plug of claim 1, wherein the third projection has a length that is thirty percent, or less, of lengths of the first and second projections.

4. The plug of claim 1, wherein the third projection has a length that is twenty percent, or less, of lengths of the first and second projections.

5. The plug of claim 1, wherein the first and second projections are of substantially the same length.

6. The plug of claim 1, further comprising a magnet or ferrous portion which is arranged to provide a magnetic retaining force between the plug and the socket.

7. The plug of claim 6, wherein the magnetic retaining force is sufficient to help retain the plug in a connected condition with the socket, however the magnetic retaining force is not large enough to prevent the plug from being disengaged from the socket.

8. The plug of claim 1, wherein each of the first and second projections comprises an electrical contact portion for a noise cancellation signal and an electrical contact portion for an audio signal.

9. The plug of claim 1, wherein the first and second projections comprise electrical pins.

10. The plug of claim 1, wherein the third projection is of substantially squat form.

11. The plug of claim 1, wherein the third projection includes a rounded formation.

12. The plug of claim 1, further comprising an electrical socket arranged to connect with the plug.

13. The plug of claim 2, wherein the first and second projections are of substantially the same length.

14. The plug of claim 3, wherein the first and second projections are of substantially the same length.

15. The plug of claim 4, wherein the first and second projections are of substantially the same length.
