Abstract

A kit of parts (1) comprising an electric cable (3) comprising hermetically sealed electric conductors, a connection device (5) comprising a first (9a) and a second connection part (9b), the first and second connection part each comprising a cavity (12) in which a respective secondary conduction coil (14) is arranged and connected to respective electrical contacts. In a connected arrangement of the connection device and the electric cable, the wire is wound around both the first connection part in a first winding sense and around the second connection part in a second, opposite winding sense. Thus, a watertight electric connection between the cable and the connection device is established.

Claims

1-13. -13. (canceled)

14. A luminaire, comprising:

an electric cable comprising a respective hermetically sealed electric conductor,

a connection device comprising at least one pair of a first and a second connection part, the first and second connection part each comprising an outer wall with a closed outer surface, said outer wall enclosing a cavity in which a respective secondary conduction coil is arranged, each secondary conduction coil being connected to respective electrical contacts, wherein, in a connected arrangement of the connection device and the electric cable, the wire is wound around both the first connection part in a first winding sense and around the second connection part in a second, opposite winding sense.

15. The luminaire as claimed in claim 14, wherein the electrical cable comprises a live wire and a neutral wire, each with a respective electric conductor, said wires being split/splittable from each other, with their respective electric conductor remaining hermetically sealed.

16. The luminaire as claimed in claim 14, wherein said outer surface of each connection part has a spiral contour, the spiral contour on the first connection part being opposite to the spiral contour on the second connection part.

17. The luminaire as claimed in claim 14, wherein the wire is held by at least one wire clamp.

18. The luminaire as claimed in claim 14, wherein the connection device comprises a plurality of pairs of first and second connection parts.

19. The luminaire as claimed in claim 14, wherein the connection parts protrude from the connection device in a direction either transverse to or along the electric cable.

20. The luminaire as claimed in claim 14, wherein the electrical connections in the connection device or the connection device and the lighting device are hermetically sealed from the environment.
