  • the invention relates to an insulation displacement device for contacting the outer conductor of RF coaxial lines.
  • an insulation displacement device which consists of an insulating bottom part, on which four vertically standing and tapered contact elements are arranged.
  • the insulation displacement device also consists of an insulating housing cap, which has a recess in it for receiving a coaxial conductor. For contacting, the housing flap with the inserted coaxial conductor is pressed against the insulating base part with the vertically projecting contact elements, the contact elements cutting through the outer insulation of the coaxial line and thus contacting the outer conductor.

  • Two locking arms are provided on both sides of the bottom part, which engage with their locking projections in corresponding counter-locking mechanisms on the outside of the housing cap.
  • Both the bottom part and the housing cap are made of plastic. Although this serves to insulate the contact elements, it has the disadvantage that both the latching arms and the counter-latches are made of plastic and thus under extreme loads such as high temperatures, large forces or high dynamic loads on the plastic begins to flow or deform and consequently a reliable contacting of the outer conductor is no longer guaranteed.
  • This insulation displacement device for contacting an outer conductor of an RF coaxial line is known from the as yet unpublished German patent application with the official file number 19742646.8.
  • This insulation displacement device consists of two metal optical insulation displacement contact holders and an insulating intermediate housing made of plastic.
  • Insulation displacement contact holders are each made up of a base plate and four webs, a contact cutting edge being arranged on both sides on the inside of the webs and a locking projection on the outside.
  • the insulation displacement contact holders can be inserted into the intermediate housing from both sides, grooves being formed for the webs in the intermediate housing with latching openings which interact with the latching projections on the webs of the insulation displacement contact holder.
  • the two insulation displacement contact holders are pushed into the intermediate housing in a first pre-latching position, then the coaxial line is inserted between the two insulation displacement contact holders and the two insulation displacement contact holders are pressed together, as a result of which the respective cutting edges sever the insulation of the coaxial line.
  • connection box consists of a metal housing open towards the top, which is slotted in the side walls to accommodate the coaxial lines.
  • connection box After inserting the coaxial lines, the connection box is closed from above by a cover. Openings are provided on the cover, through which tabs provided on the connector box when the cover is placed are passed and then bent.
  • the coaxial lines are fixed by putting the cover on.
  • the invention is therefore based on the object of demonstrating an insulation displacement device for contacting the outer conductor of an RF coaxial line, which is simple and inexpensive to manufacture, which ensures reliable contacting of the outer conductor even under extreme conditions, and which allows simple automated assembly. According to the invention, this object is achieved by an insulation displacement device
  • a cutting edge is provided for contacting the outer conductor of the RF coaxial line.
  • the design of the latching means and the counter latches made of metal ensures that the insulation displacement device does not come loose even under extreme loads and that contact is made with the outer conductor of the RF coaxial line.
  • the insulation displacement device Since only two metal parts are used for the insulation displacement device, it is simple and inexpensive to manufacture and is easy to assemble.
  • the assembly is simplified in that the two parts can be mutually fixed in a pre-locking position and in this pre-locking position the RF coaxial line can be inserted between the two parts.
  • the two parts guide each other when pressed together, so that the assembly effort is reduced to a minimum.

  • FIG. 1 shows the insulation displacement device according to the invention in the open state.
  • the insulation displacement device consists of two metal parts 1 and 2, which accommodate a coaxial line shown in broken lines between them.
  • Each of the parts 1 and 2 consists of a base plate 3 on the outside of which four webs 4 extending perpendicular to the base plate 3 are arranged. Of the four webs 4, two are directly opposite each other. In the angle between the webs 4 and the base plate 3, cutting edges 5 are arranged on both sides of the webs 4.
  • Each part 1 or 2 thus has eight cutting edges 5.
  • Each cutting edge 5 is essentially rectangular when viewed in the direction of the coaxial line to be received, and two opposing cutting edges 5 are each spaced apart from one another by a gap 6.
  • each of the webs 4 outward or inward curved locking tabs 8 are provided as locking means and locking windows 9 are provided as counter locking means.
  • the latching windows 9 are each free End of each web 4 and the locking tab 8 between the locking window 9 and the base plate 3 are arranged.
  • each web 4 is provided with a bevel 10. If one considers the insulation displacement device in the longitudinal direction of the coaxial line to be received, the slope 10 runs on one side on the front two webs 4 of the lower part 1 and on the other side on the rear two webs 4 of the lower part 1. At the upper part 2, the bevels 10 are complementary.
  • the locking tabs 8 are each bent out in the direction of the slopes 10.

  • the two parts 1 and 2 are placed one on top of the other, the webs 4 being laterally displaced by the bevels 10.
  • the front webs 4 and the rear webs 4 are laterally offset from one another, as seen in the longitudinal direction of the coaxial line to be accommodated.
  • the two parts 1 and 2 can easily be pre-assembled by machine, since the webs 4 brace with one another. In a pre-locking position, not shown, the webs 4 overlap to such an extent that the parts 1 and 2 fix each other by the clamping action of the webs 4 and a coaxial line can nevertheless be inserted.
  • parts 1 and 2 are only pressed together along the webs 4, the cutting edges 5 penetrating with their cutting edges 7 through the insulation of the coaxial line and thus contacting the outer conductor.
  • parts 1 and 2 When parts 1 and 2 are pushed together, they guide one another, the two of the webs 4 leading along each other and the web running on the inside in a U-shaped recess 11, which is formed by the two cutting edges 5 and by the web running outside 4 is formed, is recorded. Due to the inclusion of the inner web in the respective U-shaped recess 11, the two parts 1 and 2 are exactly guided in the assembled state.
  • the latching lugs 8 engage in the latching windows 9 and thus also fix the parts 1 and 2 against one another in the direction of displacement.
  • Two latching tabs 8 are in engagement with associated latching windows 9 on each pair of adjoining webs 4.
  • both parts 1 and 2 are made entirely of metal and thus the locking tabs 8 and the locking window 9 are made of metal, there is no risk that the insulation displacement device will come loose even under extreme loads.

Abstract

L'invention concerne un dispositif autodénudant permettant de mettre en contact le conducteur extérieur de lignes coaxiales HF. Ce dispositif autodénudant comprend deux parties métalliques (1 et 2) munies de moyens d'encliquetage (8) et d'éléments antagonistes (9), ainsi que de tranchants (5). La mise en contact du conducteur extérieur s'effectue par compression interactive des deux parties métalliques, afin qu'elles s'encliquettent mutuellement. Comme il n'est pas prévu pour assurer l'encliquetage d'utiliser des pièces en matière plastique, le dispositif autodénudant convient à des utilisations dans des conditions extrêmes, telles que des températures élevées et des sollicitations dynamiques importantes.
