  • FIG. 4 it is also possible to fasten the cover 20 directly to the second end wall 12 in which case the insulating plates are not fitted and the cover 20 is screwed directly on the periphery of the second end wall 12 by means of the screw thread 24.
  • FIG. 3 shows a further possibility which can also be used in the arrangement according to FIG. 2; it shows how the cable drum may be protected from too much heating.
  • the first end wall 11 there are ventilation openings 29, in the second end wall 12 ventilation openings 29' and in the insulation plate 21' ventilation openings 30. All the ventilation openings 29, 29 and 30 are distributed around the periphery. The air can find its way through from one side to the other by these ventilation openings 29, 29' and 30 and also through the ventilation opening 28 in the cover 20; thus the heat produced by the lamp 17 is taken up and carried away.
  • the feet 31 on the first end wall 11, which also are used for positioning the cable drum protrude sufficiently far from the end wall 11 so that when a cable drum is placed on the feet 31 there is sufficient space left for drawing in the air.
  • the flow of the cooling air is shown by arrows in FIG. 3.
  • the feet 31 are long enough so that the connecting cable together with its plug can be inserted into the socket 7 without difficulty.
  • the drum body in the arrangements according to FIGS. 1 to 4 is mounted so that it can be rotated in a two part housing 1, 2, the housing beingprovided with a carrier.
