Definitions

  • the invention relates to a cable sleeve according to the preamble of claim 1.
  • a cable sleeve of this type is previously known from US-PS 4,062,615. This is provided with several connection elements for contacting a multi-core ribbon cable.
  • the individual cores of the ribbon cable lying next to one another have a common insulation which encloses the electrically conductive cores.
  • the two ends of the incoming and outgoing ribbon cables to be connected are in the lower part of the cable sleeve.
  • the contact is made by the large number of connection elements arranged side by side in the upper part of the cable sleeve, provided with insulation displacement contacts, which penetrate into the insulation of the ribbon cable from the top with their insulation displacement contacts and electrical contact connections between the wires to be connected in each case to the incoming and the outgoing ribbon cable produce.
  • the invention is therefore based on the object to provide an inexpensive to produce cable sleeve of the generic type, which enables an electrical connection between two twin-core drop wire cables without the two wires with their thick insulation must be separated from each other and without the distance between the Cores of the twin-wire drop wire cable must be exactly the same.
  • connection elements Since the two insulation displacement contacts penetrate on both sides to the central axis of the double-wire drop wire cables, different distances between the two wires do not impair the connection process and the contact connection between the wires and the insulation displacement contacts of the connection elements. Another advantage is that the upper and lower part on the one hand and the connection elements arranged in the upper and lower part on the other hand can be constructed exactly identically, so that a considerable cost saving can be achieved.
  • the guide channels can be U-shaped, with the incoming and outgoing twin-core drop-wire cables inserted into the guide channels each approximately 180 ° in the respective guide channels, which relieves the strain on the twin-wire drop cable.
  • the cable sleeve consists of an upper part 2 and a lower part 3 of identical construction. Only the lower part 3 shown in FIG. 1 is described below.
  • the lower part 3 consists of a plate-shaped base body 1 with bevelled side edges.
  • two 0-shaped guide channels 13 are formed, which together form the shape of an "8".
  • there is a further guide channel 14 which runs in the middle and transverse to the base body 1 seen that runs exactly through the central region of the 8-shaped guide channels 13.
  • the guide channels 13 and 14 are made in the form of grooves in the base body 1, the groove in the central region of the 8-shaped guide channels 13 being exactly twice as wide as the groove in the region of the guide channels 13, 14.
  • the guide channels 13, 14 are used for U-shaped insertion of the incoming and outgoing twin-core dropwire cables 9.
  • a Z-shaped clamping groove 18 is arranged centrally and transversely to the longitudinal axis of the base body 1 of the cable sleeve, the end regions of which intersect the guide channels 13 at an angle of approximately 45 °.
  • a Z-shaped connecting element 4 is inserted, the central web 5 of which in the region of the clamping groove 18 running transversely to the longitudinal axis of the base body 1 and the insulation displacement contacts 6, 7 each arranged in the 45 ° to the guide channels 13 Regions of the clamping groove 18 are arranged.
  • Receiving grooves 15 are introduced into the base body 1 at an angle of approximately 90 ° to the end regions of the Z-shaped clamping groove 18, which run at an angle of approximately 45 ° to the guide channels 13.
  • These receiving grooves 15 are used to receive the parts of the connecting element 4 located in the upper part 2 which protrude beyond the inside of the base body 1.
  • the insulation displacement contacts 6, 7 of the Z-shaped connecting element 4 each comprise a clamping slot 8, the width of which is smaller than the diameter of the Cores 11, 12 of the twin-core drop wire cables 9 to be connected.
  • the base body 1 of the lower part 3 of the cable sleeve is provided on one long side with a recess 16 and on the other long side with a correspondingly shaped recess 16, which protrudes beyond the base body 1.
  • the insulation displacement contacts 6, 7 of the Z-shaped connecting element 4 located in the lower part 3 from the insulation displacement contacts 6, 7 of the Z-shaped connecting element 4 located in the lower part 3, the insulations 10 of the respective lower wires 11 are cut and the wires 11 are electrically contacted and conductively with one another connected.
  • the insulation displacement contacts 6, 7 of the Z-för located in the upper part 2 Migen connecting element 4 cut through the insulation 10 of the upper wires 12 and electrically contacted and electrically connected to the upper wires 12. According to the invention, both of these are carried out from the narrow side 19 of the twin-wire drop wire cables 9.
  • the insulation displacement contacts 6, 7 each have pointed cutting edges 31 at the upper end, which reduce the insertion forces.
  • connection elements 4 are mirror images of one another, forming an X-shape to the transverse axis of the base body 1, thereby preventing an electrical Connection of the connection elements 4 with each other, the center webs 5 of which are of a lower overall height than their end parts with the insulation displacement contacts 6, 7.
  • the upper and lower parts 2, 3 are pressed together, the upper edges of the connection elements 4 engage in the area of the insulation displacement contacts 6, 7 into the opposite receiving grooves 15 of the other part.
  • a cable strain relief is created by the U-shaped guidance of the ends of the two twin-core drop wire cables 9.
  • the lower part 3a consists of a basic body 1a, which is formed differently to the left and right of its transverse axis.
  • the base body 1a In the left part (FIG. 4), the base body 1a has a guide channel 13a for the double-wire drop cable 9a standing upright on its narrow side 19.
  • the guide channel 13a ends in front of a central partition wall 25.
  • opposing clamping ribs 23 are arranged on both side walls, which provide strain relief for the upright inserted double-wire drop cable 9a.
  • the base body 1 a is provided on the left side in FIG. 4 on both longitudinal sides with stepped recesses 20. In the vicinity of the dividing wall 25, a wider cutout 26 is provided, which extends obliquely at an angle of 45 °.
  • a receiving groove 21 for the U-shaped connecting element 4a which will be described later, runs parallel to this at 45 ° to the guide channel 13a.
  • the main body 1 a has a cavity delimited by outer side webs 22, into which the part of the main body 1 a of the upper part 2 a delimited by the cutouts 20 fits.
  • a web 28 which extends at an angle of 45 ° to the longitudinal axis of the main body 1a and is pierced by a guide channel 14a and which has a receiving groove 24 which runs at 45 ° to the longitudinal axis of the main body 1a for receiving the U-shaped one Connection element 4a is provided.
  • the web 28 of the lower part 3a fits exactly into the recess 26 of the upper part 2a.
  • a slot 29 is provided in the region of the partition 25, which runs along the main body 1a and which receives the central web 5a of the U-shaped connecting element 4a.
  • the U-shaped connecting element 4a has insulation displacement contacts 6a, 7a in its two end regions angled at 45 ° to the narrower central web 5a, each with a clamping slot 8a, the width of which is smaller than the diameter of the wires 11, 12 of the double-wire drop cable 9a.
  • the incoming twin-wire drop cable 9a is first pressed with its narrow side 19 into the guide channel 13a of the lower part 3a, the clamping ribs 23 serving to relieve strain.
  • the outgoing twin-wire drop wire 9a is pressed with its narrow side 19 into the upper part 2a of the cable sleeve.
  • the upper and lower part 2a, 3a are then plugged onto one another and pressed together, the insulation displacement contacts 6a, 7a of the U-shaped connecting element 4a of the lower part 3a penetrating into the insulation 10 of the lower wires 11 of the two double-wire drop cable 9a.
  • the insulation displacement contacts 6a, 7a of the U-shaped connecting element 4a of the upper part 2a penetrate into the insulations 10 of the upper wires 12 of the double-wire drop wire cables 9a a. Subsequently, the wires 11 and 12 of both double-wire drop-wire cables 9, 9a are pressed into the insulation displacement contacts 6a, 7a and electrically connected to one another via the respective connection elements 4a.
  • cutting edges 31 are provided to reduce the indentation forces at the upper end of the insulation displacement contacts 6a, 7a.
  • connection elements 4a are offset one above the other, since the connection elements are not arranged in the center.
  • the areas of the inner connecting elements 4, 4a are marked on the outer sides of the base bodies 1, 1a by outer webs 30, 30a.
