Definitions

  • the invention relates to a method of sealing cable entries, especially against moisture and liquids, using a sealing gel of the kind specified in the precharacterising clause of claim 1, and to a corresponding cable entry or a cutting /clamping connector having at least one such cable entry.
  • a sleeve housing is known from DE-A-41 42 586 which has cable entries in which the sealing region is filled with a sealing gel.
  • DE-A-40 29 082 discloses cable entries with elastic or plastic, compressible seals.
  • the problem with which the invention is concerned is to provide a solution with which it is possible for residual cavities also to be closed in a moisture-impermeable manner.
  • the procedure according to the invention ensures that even those cavities which cannot be reached by the gel are sealed, since the sealing grease additionally provided can easily be pressed into those spaces.
  • the invention provides for the housing parts that are movable for the purpose of contacting and closing the housing to be provided, at least in regions, with a sealing grease which, in the contact position, is pressed into the cavities that are not reached by the gel.
  • the invention also provides a cable entry, for example into cable conduits, housing walls, cable sleeves or the like, which is characterised in that regions filled with sealing grease are associated with regions filled with sealing gel.
  • the invention further provides a cutting /clamping connector for electrically insulated conductors, the housing of which connector is filled, at least in regions, with a sealing gel, while sealing regions that cannot be reached by the sealing gel are filled with a viscous sealing grease.
  • the grease coating volume is advantageously greater than the residual volume of the housing available to the grease in the contact position, thus reliably ensuring that the grease is also pressed into all c ⁇ 'ities.
  • a gel having the features already indicated above is also used here.

  • Fig. 4 and 5 are views onto a housing entry or a conduit transition as a cable entry according to the invention.
  • Fig. 6 shows a longitudinal section through a corresponding component of a different construction.
  • the cutting/ clamping connector generally designated 1 is used to connect two electrically insulated conductors 2 to each other in an electrically conductive manner by means of a contact blade 3 arranged in the inner housing part 4 of the cutting /clamping connector 1.
  • the surplus lengths of the conductors 2, designated 2a in Fig. 1, are cut off using cutting blades 6 and are pulled to the left out of the cutting/ clamping connector 1.
  • the housing lids designated 9a and 9b are pressed onto the middle part of the housing.
  • Both the through-channels for the conductors 2, designated 10 in Fig. 3, and a central test bore 7 are filled with a sealing gel 8 into which the conductors 2 can be pressed and through which a test probe of a testing element can be pushed until it reaches the contact blade 3.
  • the movable housing parts 9a and 9b are filled at their inward-facing surface with a sealing grease 11, this sealing grease filling not being shown in the right-hand half of the drawing in Fig. 3.

  • the gel may adhere to the periphery of the channel 10 and, in regions, to the conductor 2, because of the relatively high surface tension of the gel a longitudinal channel, designated 12 in the right-hand half of Figure 3, may be produced between the housing parts 4 and 9, which channel is totally sealed according to the invention with grease 11, as can be seen from the left-hand half of Figure 3.
  • Fig. 4 shows a cable entry, generally designated la, with housing parts 4a and 9a which are movable towards each other and are pressed against each other in the closed position and which are shown as half-shells having dovetail longitudinal guides 13 at the sides, which half shells are held together by a clip element 14.
  • one housing part namely housing part 4a
  • the housing part 9a has an excess filling of grease Ila which, as has already been described in detail above, is able to penetrate into longitudinal gaps between, for example, the entering cable 2a and the gel 8a.

  • both of the housing halves, designated 4b and 9b are provided with a gel filling 8b, a supply of grease lib being provided on the inner surface of one of the gel fillings.
  • Fig. 6 shows the possible axially serial arrangement of a gel filling 8c and, behind it, a grease filling lie in a conical reservoir in such a manner that, when the housing halves 4c and 9c are joined together, part of the grease filling lie is able to penetrate into any gaps, slits, cavities or the like that may still be present.
  • the described embodiment of the invention may, of course, still be modified in many respects without departing from the underlying concept.
  • the invention is not limited to the cutting/ clamping connector shown here, but other clamping connectors, which dispense with cutting of the cable cores or conductors, may be equipped in a corresponding manner, and so on.

Abstract

L'invention se rapporte à un procédé de scellement des entrées de câble pour les rendre étanches à l'humidité et aux liquides, ainsi qu'à une entrée de câble elle-même ou connecteur (1) par coupure/serrage, ce procédé permettant également de fermer d'une manière imperméable à l'humidité les cavités résiduelles. On réalise ce scellement par le fait que les composants fournis pour établir un contact et fermer la région d'entrée sont en outre munis, au moins dans certains endroits, d'une graisse d'étanchéité (11) qui, dans la position de contact, est pressée dans les cavités que ne peut atteindre le gel (8).
