Definitions

  • the innovation relates to a connecting device for a ribbon cable with an essentially strip-shaped insulating material body, which has a slit-shaped first transverse channel for receiving a ribbon cable section, with a plurality of contact elements which are anchored perpendicularly to the first transverse channel in the insulating material body and each with a single conductor of the ribbon cable are connectable and with a U-shaped strain relief bracket, which can be attached with its two legs to the insulating body and whose crossbar forms a second transverse channel with the insulating body, which runs parallel to the first transverse channel and has essentially the same cross section.
  • Such a connecting device is known for example from DE-AS 26 53 592, the first transverse channel in the insulating body being adapted to the ribbon cable to be contacted in such a way that in the transverse channel one of the contact elements anchored in the longitudinal direction is perpendicular to a cable core of the ribbon cable and can be connected to this.
  • the flat cable going away from the connecting device is clamped with the second transverse channel, which is formed by the attached strain relief bracket at the end opposite the plug side of the connecting device.
  • the cable is bent around at least two edges of the insulating material body, namely when it emerges from the first transverse channel and when it enters the second transverse channel.
  • the cable can then exit the second cross channel in the Rich device of this transverse channel, ie perpendicular to the plug direction of the connecting device, be led away. However, it can also be bent around a further edge, this time an edge of the strain relief bracket, when it emerges from the transverse channel and from there it can run in the longitudinal direction, ie, counter to the plugging direction of the connecting device.
  • connection device in which the strain relief bracket is made of metal.
  • the strain relief bracket consisted of insulating material.
  • the strain relief bracket did not be touched from the outside.
  • the object of the innovation is to design a connection device for a ribbon cable of the type mentioned in such a way that the strain relief for the ribbon cable is improved.
  • this connecting device it should be possible with this connecting device to insert and fasten a ribbon cable in such a way that the free conductor ends can be covered so that they cannot be touched.
  • this object is achieved in that a longitudinal channel is formed in the crosspiece of the bracket, which is perpendicular to the second transverse channel branches and opens into a cable outlet opening, which in turn has essentially the same cross section as the transverse channels.
  • the strain relief bracket is therefore provided with an additional longitudinal channel, so that the inserted flat cable is bent again around a further edge within the second transverse channel and is led out through the cable outlet opening against the direction of insertion of the connection device.
  • the flat cable is therefore always bent around three edges starting from the first transverse channel, so that a strain relief for high requirements is achieved.
  • the second half of the cross channel can accommodate the free end of the flat cable, so that the conductor ends of the individual cable cores are secured against contact.
  • the longitudinal channel is expediently formed in the region branching off from the transverse channel with approximately twice the width of the transverse channels, so that the ribbon cable can be accommodated twice in it. This means that the free cable end can also be bent into the longitudinal channel.
  • the longitudinal channel then narrows in steps towards the cable outlet opening so that the free conductor ends of the ribbon cable are reliably covered against external contact.
  • the connecting device shown in the drawing represents a plug which comprises a strip-shaped insulating material body 1 as the basic element; this insulating body 1 is assembled from a base part 2 and an upper part 3.
  • contact elements namely connector springs 4 are arranged in two rows.
  • the upper part 3 there is formed a transverse channel which extends almost the entire width of the insulating material body, the cross section of which is adapted approximately to the cross section of a ribbon cable 6.
  • a strain relief bracket 7 which is fastened, for example locked, to the insulating body 1 with the two side legs 8.
  • the crossbar 9 of the bracket 7 also forms with the upper part 3 a further transverse channel 10, which is also adapted in cross section to the cross section of the ribbon cable 6.
  • the connection device shown still corresponds to an embodiment already used.
  • a longitudinal channel 11 is also formed in the transverse web 9 of the strain relief bracket 7, which branches off from the second transverse channel 10 perpendicularly to the latter and thus extends in the direction of the contact elements 4.
  • This longitudinal channel 11 opens at the top of the bracket 7 into a cable outlet opening 12, the cross section of which in turn corresponds approximately to the cross section of the ribbon cable 6.
  • the longitudinal channel 11 has approximately twice the width of the outlet opening 12 or the transverse channels 5 and 10. In this area there is therefore space for a double cable layer.
  • a ribbon cable section is introduced into the first transverse channel 5 of the base part 2.
  • the base part 2 is combined with the upper part 3 in a known manner inserted, wherein in each case a contact element 4 is brought into a solderless connection with a line core of the ribbon cable 6.
  • the section 6a of the contacted ribbon cable 6 is bent around the edges 3a and 3b of the upper part 3, then extends in the transverse channel 10 to the longitudinal channel 11 and is bent there around a further edge 7a of the strain relief bracket 7.
  • the ribbon cable 6 comes out through the opening 12.
  • the free end section 6b of the ribbon cable 6 emerges from the first transverse channel 5 in the opposite direction to the previously described section and into the second transverse channel 10, from where it is then guided parallel to the continuous cable into the longitudinal channel 11 and in its section 13 ends.
  • the conductor ends of the ribbon cable are thus secured against external contact.
