Definitions

  • the invention relates to a strain relief device for connected to circuit cards, connecting plates, plug-in units and the like, e.g. soldered conductor tracks, which consists of two clamping pieces that can be locked together by means of elastic locking elements, between which the conductor tracks are clamped.
  • Strain relief devices are always required when cable strings, conductors etc. are attached to a plug, a plug-in unit or the like, to which a certain tensile force is exerted, which in no way affects the line connection, e.g. the solder joint may be transferred. This is particularly true when plug connections can only be solved by pulling on the cable due to their small dimensions and difficult accessibility, or at least it can be expected that the connector will be released in this way.
  • the clamping force for the cable is generated by means of a screw and transferred to the clamping bracket.
  • the assembly of the cables is therefore complex, and there is also no control that the clamping force is correctly dimensioned. If the clamping force is too low, there is a risk that the cable will slip, while if the clamping force is too strong, the insulation may be damaged.
  • the invention has for its object to provide a strain relief device which can be produced at low cost, which reliably secures cable bundles of different designs and can be handled easily without damage to the cables or the insulation occurring.
  • This object has been solved according to claim 1 with the Z ugentlastungs liked.
  • a particular advantage of the strain relief device according to the invention can also be seen in the fact that the two clamping pieces are of identical design, which simplifies storage.
  • FIG. 1 shows a cable 10 with a number of conductor tracks 11, the ends of which are soldered to a number of contact connections with holes 12 in a circuit card 13.
  • the circuit lines 14 on the card are conductively connected, e.g. soldered, with spring contacts of a plug unit 15.
  • the strain relief device consists of an upper clamping piece 16 and a lower clamping piece 17.
  • the clamping pieces 16 and 17 are formed in one piece and identically and consist of a flexible, not too brittle and moisture-resistant material. A material made from an optimal combination of toughness, impact resistance, heat resistance and dimensional stability is preferred. Since the clamping pieces 16 and 17 are, as mentioned, identical, their shaped elements are designated by the same reference numerals.
  • Each clamping piece 16, 17 is provided on its outer surface 18 at one corner with a recess 19 and at the corner located diagonally thereto with a locking recess 20. There is a hole 21 in the recess 19, and the locking recess 20 has a V-shaped locking projection 22. At the in Neren surface 23 of each clamping piece 16, 17 is a locking pin 24 at one corner, while a locking hook 25 is formed on the diagonally opposite corner.
  • the hole 21 and the locking pin 24 as well as the locking recess 20 and the locking hook 25 are each located at opposite ends, so that when the upper clamping piece 16 and the lower clamping piece 17 interact, when these have turned towards one another (FIG.
  • the locking pins 24 also the holes 21 aligned and the locking hooks 25 are assigned to the locking recesses 20.
  • a recess 26 for receiving the conductor tracks 11 is also provided on the inner surface.
  • Fig. 1 shows that the locking pins 24 are forked and provided at their ends with lugs 27.
  • Each locking hook 25 carries a V-shaped hook part 28.
  • pin holes 29 at the corners of the circuit card 13 facing away from the plug unit 15.
  • the upper clamping piece 16 is placed with its inner side, ie the recess 26, on the free edge of the card 13.
  • a resilient pressure piece 30 can be inserted between the clamping piece 16 and the conductor tracks 11.
  • the locking pin 24 is inserted into the 'assigned pin hole 29 of the card 13 and the clamping piece 16 pressed against the card 13 so that the conductors get into the recess 26, the locking pin 24 and the locking hook 25 projecting beyond the thickness of the card 13 and the hole 21 in the recess 19 is aligned with the associated pin hole 29 of the card 13.
  • the lower clamp 17 is placed in reverse orientation from below so that its inner surface 23 with the recess 26 faces the lower surface of the card 13 and its locking pin 24 is aligned with the pin hole 29 in the card 13 and the hole 21 in the upper clamp 16 is.
  • the two clamping pieces 16, 17 are pressed together and assume the position shown in FIG. 2.
  • the locking pin 24 of the lower clamping piece 17 now protrudes through the pin hole 29 of the card 13 and the hole 21 of the upper clamping piece 16, the lugs 27 acting on the upper surface of the recess 19 in a locking manner.
  • the two halves of the locking pin 24, which is designed as an expansion pin are pressed together and expand automatically as soon as the lugs 27 have passed through the hole 21.
  • the hook part 28 of the locking hook 25 and the lower clamping piece 27 comes into engagement with the locking projection 22 on the upper clamping piece 16, as shown in FIG. 2.
  • the locking hook 25 of the upper clamping piece 16 also engages in the locking projection 22 of the lower clamping piece 17.
  • the shape of the recess 26 in the inner surface of the upper clamping piece 16 causes a portion of the conductor tracks 11 to be held on the card 13, and since the clamping pieces 16, 17 protrude with their inclined surfaces in the recesses 26 beyond the edge of the card 13 another section of the conductor tracks 11 clamped directly between the clamping pieces 16 and 17.
  • the connecting elements between the clamping pieces 16 and 17 are unlocked in the usual way.
  • the resilient pressure piece 30 is generally used only when there are only a few conductor tracks to befe are, as shown for example in Fig. 1. With a larger number of conductor runs 11, as in the illustration according to FIG. 2, such a pressure piece is not necessary.
