Definitions

  • Fastening device for fastening an electrical and / or optical cable to a cable end piece.
  • the invention relates to a method for fastening an electrical and / or optical cable to a cable end piece according to the preamble of claim 1 and a fastening device for an electrical and / or optical cable according to the preamble of claim 10.
  • the invention is particularly suitable for fastening optical fibers on optical connectors.
  • a disadvantage of crimping is that all tolerances must be compensated for. In particular, they are
  • the known methods and devices, which involve clamping or squeezing the cable jacket, are relatively complex and labor-intensive.
  • adhesives generally have the disadvantage that the security of the various adhesives with the different cable sheath materials does not meet the required requirements in all application conditions. Especially when it comes to temperature and humidity, the adhesive and the cable sheath come off partially.
  • Another disadvantage of using adhesives is that they are difficult to handle, taking safety measures for employees into account and ensuring that the quality of the adhesive remains the same.
  • the invention is based on the object of providing a method and a fastening device which provide the connection of a cable to a cable end piece in a simple, inexpensive and reliable manner.
  • the solution according to the invention is characterized in that at least one cable jacket end of the cable jacket is first made available.
  • the cable jacket is slit, for example, at one end into one or more end pieces, the end pieces being referred to as cable jacket ends.
  • the cable jacket ends are then bent or folded around an edge of a holding part.
  • the fastening of the cable jacket according to the invention is based on the fact that a tensile force on the cable or the cable jacket is absorbed by the edge by bending the cable jacket end around an edge. The sharper the edge and the more the cable jacket end is bent, the higher the pull-out strength of the cable jacket attachment.
  • the cable jacket end is therefore preferably placed around a sharp edge of a holding part.
  • a cable end piece in the sense of the invention is to be understood as any device which receives the end of an electrical or optical cable.
  • it is an electrical or optical connector that is coupled to an associated connector receptacle.
  • a cable sheath in the sense of the invention means any outer covering of a cable.
  • the holding part used can be an already existing part of the cable end piece or alternatively a separate part that is supported on the cable end piece or is positively connected to it.
  • the cable jacket ends are preferably turned essentially 180 ° in order to provide a high degree of pull-out strength.
  • the holding part preferably runs between the folded cable jacket ends and the cable jacket. As a result, it can safely attack the kink of a folded cable jacket end.
  • the cable jacket ends can also be folded through an angle of less than 180 °. However, it should be flipped at least by essentially 90 °, since the pull-out strength is greatly reduced at smaller angles.
  • the bent ⁇ cable jacket ends are preferably fixed in relation to the cable end piece. This ensures that the cable jacket ends do not bend back and the fastening is loosened. Separate fixing elements such as brackets etc. can be used for fixing.
  • the bent cable jacket ends are inserted into slots in individual housing parts of the cable end piece and thereby fixed.
  • a fixation may also be superfluous, namely if the cable sheath remains pressed in the bent position by an already existing compression spring. It is also pointed out that the cable jacket ends can be fixed automatically by the walls or other structures of the cable end piece.
  • the fastening device according to the invention for an electrical and / or optical cable is characterized in that it has fastening means for fastening the cable jacket to the cable end piece, which have at least one holding part with an edge around which a
  • the edge of the holding part is preferably designed as the sharpest possible edge, ie the edge has a small radius of curvature.
  • the holding part is part of the cable end piece, the holding part in a preferred embodiment is a thinly shaped sheet metal with a first side edge and a second side edge, the first side edge abutting the fold point of the folded cable jacket end and the second side edge resting on a projection of the cable end piece. This projection is in particular the wall of a chamber which receives the cable to be coupled.
  • the holding part in a preferred embodiment is a sheet metal bracket which is positively connected to the cable end piece.
  • a cable jacket end is placed around an edge of the angle.
  • FIG. 1 is a perspective view of a multiple connector for receiving optical fibers, the cable jacket end of the optical fibers being folded through 180 °,
  • FIG. 2 shows a detailed view of the folded cable jacket ends of the multiple connector of FIG. 1,
  • FIG. 3 shows a cable jacket end and an associated holding part of the multiple connector of FIG. 1,
  • FIG. 4 is a perspective view of a single plug for receiving an optical fiber with cable jacket ends folded over by 180 °, the optical fiber being rotated by 90 ° with respect to the plug of FIG. 1 and lying flat in the plug, J) rt ⁇ - 1 ⁇ > c ⁇ o Ln o (_ ⁇ o L ⁇ d tu ⁇ ⁇ « ⁇ > HH) -S ⁇ 00 ⁇ oa C ⁇ SN CO ⁇ « G t " 1 s: ⁇ - ⁇ 3 ⁇ _ ⁇
