Definitions

  • the present invention relates to a tool for attaching a hose to an electrical line, a cable, a cable section, etc. Furthermore, the invention relates to a method for attaching a hose, in particular a slotted hose, to a cable or a method.
  • Hose sections used to protect an electrical line which can also be understood as a cable, a cable cut or the like, from the outside.
  • such a hose can also be referred to as a protective hose.
  • This is attached to at least a section of the cable and is used there to protect the same.
  • Such a hose can also have the property of narrowing its own diameter and constricting the free internal cross-section inside the hose when the hose is stretched. It is also possible that a surface quality of the cable makes it necessary to overcome a comparatively high coefficient of friction. This makes it difficult and time-consuming to apply the hose to the cable by hand.
  • the hose has usually been pushed onto the cable by hand or manually.
  • magnesium silicate hydrate, talc or another lubricant to reduce the friction between the outer circumference of the cable and a
  • Inner circumference of the hose are used.
  • the use of these lubricants is common however, due to sometimes unpredictable chemical or physical reactions with, for example, a material of the outer circumference of the cable or cable section, this is not desirable or lubricants may be used in clean room assembly due to the
  • Hoses on cables can therefore be time-consuming and energy-intensive, which can be a major challenge for assembly personnel in series production. Furthermore, the manual attachment of the hose requires a high level of performance and exercise

  • the hose guide section can be shaped in such a way that free ends of the hose can be brought into overlap with one another in a wake of the tool in the circumferential direction of the cable and / or the hose.
  • the hose guide section can be shaped in such a way that the hose, which was previously spread open, is closed around the cable inserted into the hose. This makes it possible that the tool only has to be guided along the longitudinal axis of the cable and this movement necessarily closes the hose around the cable.
