  • the innovation relates to an arrangement for passing a cable through a housing wall with means for fixing the cable to the housing wall, a bore corresponding to the diameter of the cable being formed in the housing wall.
  • the prior art provides for such cases that the cable is squeezed through the bore provided in the housing wall, which is preferably provided with a narrowing that is smaller than the diameter of the cable, with elastic, possibly also plastic deformation of the cable sheath.
  • Additional measures stipulate that the individual wires are sandwiched a guided through the housing wall cable between the ribs, are formed on the housing with the cable sheath cooperating barbs and / or the cable of a within the housing with Lock washer is provided.
  • a sleeve which can be attached to the housing wall and which is used for receiving the cable and the passage of the wires and which is fastened to the cable by crimping.
  • Such attachments of a cable to a housing wall offer an absolutely secure tension / pressure-relieving fixing of the cable in question and a certain sealing of the lead-through point, but they are not very suitable for series production. For one, there are additional ones
  • the task underlying the present innovation was therefore an arrangement for carrying out a
  • the solution to the problem provides that the bore is provided with an insertion countersink and that a spiral rib is formed within the bore.
  • a preferred exemplary embodiment is characterized in that the rib has at least one turn with a trapezoidal cross section and in that a stop associated with the ring-shaped end face of the cable sheath which is produced by exposing the wires of the cable is formed within the housing.
  • the innovation completely solves the task, in particular it creates a positive connection with the cable by penetrating the rib in the cable sheath, which has a sufficient sealing effect between the cable and the
  • the solution according to the innovation offers a decisive ease of assembly, since a cable can be assembled without tools using screwing movements even with considerable diameter deviations with a relatively low force, and a significant improvement in quality is thereby achieved when installing the cable.
  • the innovation makes it possible to choose the diameter of the bore in the housing wall in such a way that it corresponds to the smallest dimension of the relatively large diameter tolerance field of the cable.
  • the application of the innovation is understandably not limited to cables that contain electrical conductors according to the exemplary embodiment. It is essential that the cable jacket is structureless and at least elastically deformable. Ultimately, new hoses can also be attached to a housing wall.
  • FIG. 1 shows a side view of a rotary encoder
  • FIG. 2 shows a top view of the rotary encoder according to FIG. 1,
  • FIG. 3 shows a partial section along the section line A in FIG
  • FIG. 1 shows the multi-step housing 1 of the rotary encoder selected as an application example.
  • the housing 1 serves to accommodate a measurement sensor 2, preferably a permanent magnet / Hall generator combination, and a component for the signal processing circuit board 3.
  • a first section of the housing 1, designated 4 represents the part that projects, for example, into a gear housing and a gear or a ferro - Magnetic clock disk associated measuring head of the rotary encoder.
  • Another section 5 is provided with a 0-ring 6, which enables a sealed attachment of the rotary encoder to the relevant gear housing, the rotary encoder being fastened to the gear housing by means of a screw connection for which the housing 1 is formed with a flange 7 provided with a bushing 7. 9 with an eyelet is used to seal the screw connection.
  • a section 10 of the housing 1 is provided for the mounting of the printed circuit board 3 and the direct and inseparable fastening of a cable 11 serving for the energy supply and the measured value transmission.
  • the latter is inserted through a bore 14 in the housing wall 12 and a projection 13 formed on the latter into the housing 1 or into a stem 19 of the housing 1 which serves for easier fanning out of the wires 15, 16, 17 and 18 of the cable 11.
  • the Free-insulated conductors of the wires 15, 16, 17 and 18, one of which is designated 20, are accommodated in a suitable manner on the printed circuit board 3 and soldered to conductor tracks.
  • Circuit board 3 of the rotary encoder is completed by filling the housing 1 with a casting compound, for example a silicone compound, and curing the casting compound by heating.
  • a casting compound for example a silicone compound
  • the encapsulated housing 1 can be provided with a cover.
  • FIG. 3 shows the actual innovation with an enlarged representation of the passage of the cable 11 through the housing wall 12, 13 or the insertion of the cable 11 into the bore 1 serving for the housing 1. That is to say that the essentially cylindrical bore 14 is provided on the one hand with an insertion countersink 23 which, starting from a conical countersink 24, changes into a cylindrical socket 25 and on the other hand has a spiral circumferential rib 26, the cross section of which is triangular in the embodiment variant selected in FIG. 3 is trained. It can also be seen from FIG.
  • the sheath of the cable 11 has been elastically deformed both in the insertion recess 23 and additionally through the bore 14 and that the initial section of the cable sheath, which is carried out in the housing 1 and has not been specified, has deformed again.
  • With 27 is when screwing the cable 11 into the bore 14 due to plastic deformation designated by the rib 26 groove in the cable jacket.
  • the rib 26 also offers a sufficient sealing action with regard to external influences, but in particular prevents the casting compound from leaking out before it has hardened.
  • a dimensionally optimized embodiment provides for a diameter of the cable 11 of 6.2 ⁇ 0.2 mm for the bore 14 to be made in the housing wall 12, 13 a diameter of 6.1 mm.
  • the height of the rib 26 is dimensioned in this case at 0.25 mm. In this case, the diameter of the bore 14 thus lies in the lower region of the diameter tolerance field of the cable 11.
  • FIG. 4 shows a bore 29, which is formed in a housing 28 and serves to lead through a cable 11 and in which a spirally surrounding rib 30 with a trapezoidal cross section is formed.
  • the bore 14, 29 provided with the rib 26, 30 and thus the seat of the cable 11 according to the innovation is formed in a component which can be connected to the housing wall of a rotary encoder. This creates an interchangeability of the cable 11 and the possibility of attaching cables with different diameters when using one and the same housing.
