Definitions

  • the invention is based on a multi-pole edge connector strip according to the preamble of claim 1.
  • a connector is described, the purpose of which is to establish an electrical connection between the conductor tracks of a flexible ribbon cable and those of a printed circuit.
  • a clamp-like holding body made of metal is present, which has laterally projecting tabs which are bent after being inserted into recesses in the printed circuit.
  • the connection is detachable, but the holding body cannot often be removed from the printed circuit, since the flaps break off when they are bent over alternately.
  • the contact pressure is generated by a large number of spring tongues that press the opposite conductor tracks together. Since the spring tongues are cut in one piece from the metal holding body, the flexible ribbon cable or possibly existing conductor tracks or contact surfaces on the side on which the spring tongues lie must be insulated to avoid a short circuit.
  • the object of the present invention is to provide a multipole edge connector strip of the type mentioned at the outset, which can be produced simply and therefore inexpensively for any lengths with the same contact pressure for all spring tongues.
  • the two parts of the holding body allow the two parts to be optimally adapted to their functions.
  • the platen can consist of a stronger material, for example. This can generate a larger back pressure, as is required with a long edge connector strip will.
  • the contact pressure can be varied within certain limits.
  • the fastening of the two elements to one another by means of roller welding allows simple production from the band. Depending on where you cut the tape by means of a separating device, holding bodies of different lengths are obtained.
  • FIG. 1 denotes a printed circuit in which electronic components, not shown, are arranged on a substrate and are connected to one another by conductor tracks. Part of the conductor tracks is led to the edge of the printed circuit.
  • the electrical connection to the rest of the preceding or following electronics or circuits takes place instead of individual wires with the aid of a flexible ribbon cable 8 in the form of a transparent film on which conductor tracks are also applied on one side, in such a way that they face the conductor tracks of the printed circuit are.
  • the conductor tracks of the ribbon cable are visible in FIGS. 1 and 4, although they are on the back, since the film is transparent.
  • the conductor tracks of both the printed circuit and those of the flexible ribbon cable are congruent with one another and arranged in the same grid dimension, the width of the conductor tracks of the printed circuit being smaller in order to compensate for tolerances when covering. Of course, the arrangement is such that no short circuits can occur.
  • the Electrical connection of the conductor tracks is achieved by a clamp-like holding body 1 which, as can be seen in FIG. 1, is pushed onto the edge of the printed circuit and which presses the conductor tracks together.
  • the end of the flexible ribbon cable is placed in an arc around the edge of the printed circuit to avoid kinking. A corresponding space between the holding body and the edge of the printed circuit board is provided.
  • the holding body 1 consists — as can be seen in particular from FIGS. 2 and 3 — of two elements 2, 3 of approximately the same length. Each of these two elements is made from a different metal strip. The metal strips differ in the two exemplary embodiments shown in the figures only in their thickness. It would also be conceivable - in adaptation to the function of the elements - to use different materials and thicknesses.
  • First, the metal strips drawn off from a supply roll are individually punched and bent or embossed at the beginning of the strip in accordance with the later use. Then the two are brought together and connected to one another by spot welding or, better, roller welding. Finally, the holding body is separated in the desired length. This separation cut is made in two stages. First, the two carrier strips 9, 10 welded together are cut off at the desired location by means of a stamp. The spring tongues that are not required fall off. Then the second element is cut off and at the same time the barb 11 is cut free and angled.
  • the second element is made of a metal strip with a greater thickness. This element is therefore comparatively stiffer than the first element, which is made from a metal strip of lesser thickness.
  • the second element 3 has two line-shaped embossments 4.
  • two barbs 11 cut free are bent out of the plane at a small angle, with openings 12 in the printed one Circuit 7 cooperate in the sense of a latching.
  • Perforation holes 14 are recessed approximately in the center of the carrier strip 10 and are used for transport.
  • the carrier strip has a longitudinal groove 16 in the region of the perforation holes.
  • This longitudinal channel is used for stiffening of the element and at the same time represents a kind of handle if you want to remove the holding body from the anchors of the printed circuit after loosening the barbs. Spot or roll welding is carried out on both sides of the longitudinal channel 16.
  • the first element also has a longitudinal groove 15 in the carrier strip 9, the two longitudinal grooves lying opposite one another in such a way that they are curved in the opposite direction to the outside. Furthermore, the 1st element also has perforation holes, the position of which coincides with that of the 2nd element.
  • the end part 6 of the spring tongues presses the conductor tracks against one another.
  • the pressure counter bearing is formed by the two embossings, the end part 6 being located between the two embossings. A three-point bearing is achieved in this way, which permits precise and reliable contacting, since the holding body cannot wobble. Since the spring tongues only perform a mechanical but not an electrical function, no precious metal coating is required.
  • FIG. 1 to 3 show an exemplary embodiment of a holding body in which the two elements are of the same length.
  • FIG. 4 shows a further exemplary embodiment in which the two elements are of different lengths, namely the second element is longer than the first element.
  • This is easy to implement because the separation takes place in two stages with different cutting punches.
  • the perforation strip is first cut through, but to a greater length.
  • the spring tongues now exposed over this length fall off.
  • the last separation takes place in accordance with the desired length, offset at the same time as the production of a fastening hole 13.
  • a corresponding hole is also present in the printed circuit. With the help of this mounting hole, the printed circuit together with the holding body can e.g. be attached to a device chassis by means of a screw.
  • the separation of the holding body into two elements also allows the spring tongues to be bent over during manufacture, so that the distance between the end part of the spring tongue of the first element and the embossments of the second element can be kept very small.
