Definitions

  • the invention relates to a device for an electrical heating cable with the features of the preamble of claim 1.
  • the connecting end of the heating cable is cast in casting resin after being clamped in the housing.
  • the entire interior of the housing is filled with resin, so that practically no cavity remains.
  • Such a heating cable connection is expensive and problems can arise when pouring the housing with the casting resin, especially in unfavorable weather conditions, in that the casting resin can foam up when the moisture content is too high and insulation is not properly achieved.
  • Another disadvantage is that such a heating cable connection can no longer be dismantled after casting, so that no reassembly, for example for inspections or repair work, can be carried out.
  • the heating tape connections embedded in cast resin had to be due to the different national Ex regulations can be approved separately in the different countries.
  • the object of the invention is to develop a device with the features of the preamble of claim 1 to the effect that a multinationally approved heating cable connection is achieved, which can be installed on the construction site without resin using simple means, with differently designed heating cables can be connected, and which Is accessible for inspection and further use without destruction.

  • a locking screw 9 is provided at the end region of the housing 1, which radially in the recess 8 of the sleeve screw 5 engages.
  • the locking screw 9 is mounted in a stepped transverse hole 10, which is located in the area of the thickened wall part 2.
  • the locking screw 9 can be designed so that it can only be loosened with a special tool. In addition, it is favorable to secure the locking screw 9 in the released position on the housing 1.
  • a threaded hole 11 is also provided, into which an earth connection screw can be screwed.
  • the threaded hole 11 is also located in the thickened wall part 2 in the area between two notches 12.
  • the housing 1 can be conveniently one at each of the two opposite end regions Have sleeve screw 5 through cable entry 13, so that a corresponding cable connection can be made from both sides.
  • the in FIG. 3 shown housing 1 has only a single cable entry 13 and is otherwise designed as a closed heating cable termination.
  • housing 1 are essentially like the housing 1 of FIG. 1 and 2, however, the sleeve screws 5 used here have a strain relief 14 for fixing the cable, by means of a corresponding clamp fastening being achieved by means of screws.
  • the housing 1 is assigned elastomer seals 15 which can be used in the area of the internal thread 4 of the housing 1.
  • the elastomer seal 15 consists of a high-temperature resistant material, such as silicone or the like, and has a permanent temperature resistance, which is preferably substantially above 150 ° C.
  • the elastomer seal 15 is located between a stop washer 16 which is supported in the housing 1 and a pressure washer 17 which bears against the sleeve screw 5.

  • the insulating jacket 18 consists of a high-temperature-resistant insulating material, which can be a thermosetting plastic, for example, and comprises an insulating body 19 which is closely enclosed by the insulating jacket 18.
  • the insulating body 19 is thus located in the interior 20 of the insulating sheath 18.
  • This interior 20 is not filled with a casting resin or the like, as is usually the case, but is completely free from casting, so that the insulating body 19 is detachably mounted. There is therefore a free volume 21 on each side of the insulating body 19, which is also delimited by the end region of the insulating sheath 18 projecting beyond the insulating body 19.
  • connection terminals 24 for electrical cable conductors and a protective conductor connection 25 to which a protective conductor 26 can be connected are connected to which a protective conductor 26 can be connected.

  • the housing 1 is so small that the total free volume 21 is extremely small and is preferably less than ten cubic centimeters.
  • the free volume 21 is also less than a third of the total volume of the interior 20 in the housing 1.
  • This housing 1 is designed according to the invention as a pressure-resistant encapsulation for perfect explosion protection even at high operating temperatures. An explosion of an explosive mixture that may occur in the interior 20 is thus reliably resisted even at elevated heating temperatures, so that transmission of the explosion from the interior 20 to the atmosphere surrounding the housing 1 is reliably prevented.
  • a heating cable 32 is inserted through the upper cable entry 13 into the housing 1, the end part 33 of which is passed through the sleeve screw 5 and passes through the elastomer seal 15 as well as the pressure plate 17 and stop plate 18.
  • the elastomer seal 15 is firmly pressed against the end part 33 of the heating cable 32.
  • the temperature-resistant elastomer seal 15 is releasably secured to form an ignition-proof gap 34 in the opening 35 of the housing 1 via the clamped sleeve screw 5.
  • the thickness of the elastomer seal 15 and thus the length of the ignition-proof gap 34 is carried out depending on the size of the free volume 21 in the housing 1, so that in any case a perfect explosion-proof introduction of the heating cable 32, which heats up to about 115 ° C. and more, is ensured.

Since the housing 1 consists entirely of an insulating material, the insulating jacket 18 in this case is formed directly by the wall of the housing 1 itself. The inner surface 31 of the housing 1 thus closely encloses the insulating body 19. In this embodiment, the insulating sheath 18 is therefore a component of the pressure-resistant plastic housing 1 that is integrated in one piece from the same material.
