Abstract

In one embodiment, an electrical power distribution apparatus is disclosed which includes a track made up of a plurality of track sections 100 connected together by/to joints and end sections. The track sections are each provided with a slot 110 with which a power point connector 400 may be engaged at any point by inserting a contact member of the connector 400 through the slot 110 at a chosen point and then rotating the connector 400 by 90 degrees to bring the contact member into engagement with electrical conductors 126, 128 of the track. The apparatus may comprise a further conduit containing conductors used to distribute communication signals.

Claims

1. An electrical power supply distribution apparatus comprising:

a conduit including at least one elongate conductor, the conduit having an opening through which a connector is able to be inserted to connect electrically with the at least one conductor; and

a conductive member disposed between the opening and the at least one conductor and arranged to be electrically connected to said connector, wherein the conductive member is resiliently displaceable by said connector between a first position in which the member prevents access of said connector to the at least one conductor and a second position in which the member allows said connector to be electrically connected to the at least one conductor.

2. Apparatus as claimed in claim 1 wherein the member forms an earth connector.

3. Apparatus as claimed in claim 1 wherein the member is resiliently biased towards the opening.

4. Apparatus as claimed in claim 1 wherein the member seals the opening.

5. Apparatus as claimed in claim 1 wherein the opening is an elongate slot.

6. An extension cable comprising the electrical power supply distribution apparatus according to claim 1.

7. Apparatus as claimed in claim 1 wherein the member occludes the opening.

8. Apparatus as claimed in claim 7 further comprising a displaceable flap for the opening, the member underlying the flap.

9. In combination apparatus as claimed in claim 1 and a said connector having an electrical contact arranged to engage the conductor.

10. A combination as claimed in claim 9 wherein the apparatus comprises first and second conductors and the connector comprises first and second electrical contacts arranged to engage respective said conductors.

11. A combination as claimed in claim 10 wherein the contacts are disposed at opposed ends of an arm rotatable between a first position in which the contacts are disengaged from the conductors and the second position in which the contacts are engaged with the conductors.

12. Apparatus as claimed in claim 1 wherein the member has a sheet-like surface and a support portion engaging the conduit.

13. Apparatus as claimed in claim 12 further comprising two opposed support portions.

14. Apparatus as claimed in claim 12 wherein the or each portion is of winged form.

15. Apparatus as claimed in claim 14 wherein the or each wing comprises a plurality of individual wing portions separately connected to the surface.

16. Electrical power supply distribution apparatus according to claim 1, further comprising a further conduit containing at least one elongate conductor, said further conduit having an opening arranged to receive a data and/or communications connector to connect electrically with the conductor.

17. A combination as claimed in claim 16 and a data/communications connector having an electrical contact arranged to engage said conductor.

18. Electrical power supply distribution apparatus according to claim 16, wherein the two conduits are separated by an EMI shield.

19. Electrical power supply distribution apparatus according to claim 18, wherein the EMI shield is formed by at least a part of either or both conduits.

20. An electrical socket comprising

a housing including containing at least one conductor, the housing having an opening through which a connector is able to be inserted to connect electrically with the at least one conductor, and

a conductive member disposed between the opening and the at least one conductor and arranged to be electrically connected to said connector, wherein the conductive member is resiliently displaceable by said connector between a first position in which the member prevents access of said connector to the at least one conductor and a second position in which the member allows said connector to be electrically connected to the at least one conductor.

21. An electrical socket as claimed in claim 20 wherein the conductive member forms an earth connector.

22. An electrical socket as claimed in claim 20 wherein the conductive member is resiliently biased towards the opening.

23. An electrical socket as claimed in claim 20 wherein the opening is an elongate slot.

24. In combination, a socket as claimed in claim 20 and a said connector having an electrical contact arranged to engage the conductor.

25. A combination as claimed in claim 24 wherein the socket comprises first and second conductors and the connector comprises first and second electrical contacts arranged to engage respective said conductors.

26. A combination as claimed in claim 25 wherein the contacts are disposed at opposed ends of an arm rotatable between a first position in which the contacts are disengaged from the conductors and a second position in which the contacts are engaged with the conductors.
