  • the supports prevent the lower connection parts from being pressed in when the plug connection is made with a corresponding electrical device, so that reliable contact is also ensured here.
  • it is by the formation of Isoliers' toff stresses of two Halb ⁇ cups given the opportunity, the Kunststoff ⁇ pieces relatively far to move inwardly so that they are at a distance from the contours of the Isolier ⁇ material body, of the bending of an associated flat cable in This enables the ribbon cable to be arranged within the alignment of the insulating material body.

  • Part of the width of the upper connecting parts in particular less than a third of the width, corresponds.
  • the upper connecting parts are at a distance from the outer wall of the half-shell facing away from the joint of the half-shells and running parallel to the joint, which corresponds at least to the thickness of the flat cable.
  • the connected ribbon cable does not protrude beyond the contours of the connector, that the upper surface of the insulating body can be covered in a manner known per se by a clamping bracket which can be locked on the insulating body, wherein the clamping bracket has retracted side edges, the width of which corresponds approximately to the distance of the upper connection parts from the outer wall of the insulating body.
  • the two end caps thus formed having the catches which can be locked with the insulating material body and the passage openings for the fastening means for holding on the lower clamping shell part
  • the half-shells forming the insulating material body can be latched and / or bonded and / or welded at their lower and lateral edge parts lying in the parting line.
  • FIG. 1 shows a connector in an exploded view
  • FIG. 2 shows a part of a half-shell of the insulating body of the connector according to the invention in view and at the interfaces a-d;
  • Fig. 3 shows the insulating body partially Darge ⁇ in plan view.
  • the connector for connecting a multi-core, flat electrical cable essentially consists of two, preferably metallic, clamping shell parts 1, 2, which can be fastened to one another, for example by means of screws or rivets, a multi-part insulating material body 3, 4 for receiving, holding and guiding a large number in two parallel rows arranged Mais ⁇ pieces 5 and a clamping bracket 6 designed as a lid.
  • the insulating body 3 has an upper and a parallel to it lower surface and is clamped between the front open shell parts 1,2.
  • Each contact piece 5 has an upper connecting part 51 which extends at right angles from the upper surface of the insulating material body 3 to a common distance from it, the upper connecting parts 51 ' being at a uniform first distance from one another.
  • each contact piece 5 has a lower connection part 52 which extends at right angles to the lower surface of the insulating material body 3 up to a common distance from it, these connection parts also having a uniform,
