Definitions

  • the invention relates to a centering module for guiding and receiving a cable connector on the metallic housing part connected to the shielding of the cable for shielding purposes during the plugging process, a conductive connection to an earth potential carrier is effected.
  • a shielding element that is approximately flush with the side walls of the centering strip for shielding.
  • These shielding elements which are provided separately for each long side of the centering strip, carry individual springs which are applied to them as separate parts. When a connector is plugged in, these resiliently rest on its shielding.
  • the flat shielding elements located in the centering strip are electrically connected to regions of a module frame holding the wiring board that are at ground potential.
  • the centering module body is combined with a resilient metal element in such an arrangement that its part located on its wall when fastening the centering module in the edge region of a cutout provided for the necessary passage of the plug contacts or the mating contacts of the cable plug in a as Shielding plate serving earth potential carrier contacts the metal element in at least part of the contact area between the centering module and this shielding plate and that its part, which extends through at least one corresponding recess into the interior of the centering module, immediately rests resiliently on the metallic housing of the inserted cable connector.
  • the one-piece metal element to be applied according to the invention Due to the one-piece metal element to be applied according to the invention, a derivation for the metallic housing of the plug to be inserted is made possible in a short, direct way to an earth potential carrier without additional installation space, in particular in the interior of the module. At the same time, the extremely favorable large-area contacting is achieved.
  • the position of the part reaching into the interior is to be determined in such a way that the metallic housing of the plug to be inserted simultaneously contributes to the shielding of the centering module.
  • the metal element is a three-dimensionally designed contact spring element which, on its part located on the outer wall of the centering module, constitutes a frame formed from circumferential webs, which encloses the lower edge of the centering module and whose part which extends into the interior of the centering module is approximately vertical stands for the first part mentioned and is formed on two opposite webs in the form of at least one spring tongue with a pre-bent contact end region.
  • a contact spring element designed in this way can be produced in a simple manner from a corresponding contact spring plate in a material-saving manner and allows simple preassembly on the centering module body.
  • the material-saving production is particularly given if, according to a further development, several spring tongues are provided per web side. In the manufacture of the one-piece spring element, these individual tongues are to be produced as nested approaches, which are then bent out of the frame after the corresponding preforming of their respective end region.
  • a good connection to the shielding plate is achieved in that the web side connected to the spring tongues is cranked in several places. At these points, the broad side of the webs in question is then used to make contact with the shielding plate, as a result of which a certain large-area system is achieved.
  • spring tongues can be connected to all of the web sides forming the spring frame. If this is only the case for two opposing webs, the webs not provided with a spring tongue can be approximately at right angles to the former.
  • the centering module body is designated by 1, the contact spring element 2 forming a functional unit with it is preassembled on the module body before it, as shown in FIG. 5, is fastened to the shielding plate 20 by simply pressing it on, via the recess 30 which is matched thereto.
  • This attachment is carried out by a plurality of latching hooks 8, which are located at least on two opposite sides. After the centering module has been pressed on, these engage under the boundary line of the cutout facing away from the direction of application, so that a snap connection with good cohesion between the plate and centering module is produced.
  • These locking hooks 8 are connected as elastic parts to the centering module body and are beveled at the end pointing to the boundary line thereof in order to facilitate the insertion process into the recess provided on the shielding plate.
  • the centering module is to be inserted in the correct position when making this snap connection via the locking hooks 8. This is ensured by at least one centering mandrel 11 which is attached to the outer wall of the centering module body and which engages in each case with a corresponding recess on the cut-out edge.
  • the contact spring element 2 the development of which is shown in FIG. 4, can be produced in a simple manner from a corresponding contact spring plate in an extremely economical manner due to the cut tongues 6 to 7.
  • the contact spring element 2 is designed according to FIG. 4 so that a frame shape is predetermined by the webs 9 and 10 on the wide and the narrow side.
  • a pair of tongues 6 and 7 are respectively attached to two opposite webs 9.
  • further spring tongues of this type can also be provided.
  • Each spring tongue 6 or 7 is preformed in its respective end region facing away from the associated webs by means of a crank so that after application in each foot the tongue associated cutout 15 of the spring module body 1 can reach through.
  • a contact spring tongue In addition to the above-mentioned shaping of the upper end region of a contact spring tongue, the latter are bent approximately at right angles to the surface of the respective web 9 in the same direction. They then protrude from the frame formed by the webs 9 when the spring tongues lying opposite one another are mutually displaced from the web frame. With a corresponding design of the centering bar body, such spring tongues can in principle be attached to the individual webs in any combination. This could also be the case in the borderline case for each of these webs forming the frame.
  • the webs are cranked at places 4 provided for this purpose.
  • this cranking takes place only for the longitudinal webs 9 which carry the spring tongues.
  • preformed contact points could also be provided on any other web.
  • the webs on the narrow sides are bent at right angles in the same direction with respect to the webs on the long side. Such contact tongues are therefore only provided for the two longitudinal webs 9.
  • the prefabricated and designed in the manner described contact spring element 2 is pushed onto the side of the centering module, which is opposite its one-sided rectangular opening.
  • the angled webs 10 are approximately flush with the side wall of the centering module body within a recess matched to the width of the spring plate.
  • the longitudinal webs 9 come to rest on the surface 3.
  • the existing contact tongues 6 and 7 are located on each wall side of the module in a depression 28 corresponding to the width of the web and engage with their upper pre-shaped area in the interior of the centering module body due to an opening 15 provided in this regard.
  • the kinking surface of each spring tongue reaching into the interior forms the contact point with its shield plate when the plug is inserted.
  • the above-mentioned formations and openings are provided on the side wall of the module at the locations corresponding to these spring tongues.
  • At least the spring tongue closest to the side wall of each longitudinal wall side has points 5 which are raised at a point at the upper edge of a corresponding gradation.
  • the through openings 13 for the possible counter contacts can be seen in FIGS. 2 and 3. These through openings are inclined as a guide for the counter contacts designed to be walled inwards.
  • FIG. 5 shows the centering module attached to a shielding plate 20 by the snap connection already mentioned in the same cut as in FIG. 3.
  • the new shielding concept can be seen from this constellation.
  • This cable connector is plugged onto the free ends of the contact blades 29, for example.
  • Contact blades of this type can be arranged on a backplane wiring board of a module frame.
  • a subsequent shielding plate 20, which is connected to ground potential, can then serve as the end plate.
  • an opening of this shielding plate 20 is provided which is adapted to the dimensions of the centering module.
  • the centering module is anchored to the shielding plate 20 with the aid of the latching hooks 8 which enable a snap connection.
  • the strain relief for the cable 27 inserted into the plug is made possible by means of the metal band 26.
  • the cable plug consists essentially of the combination of a metal housing 25 with the female connector body 24.
  • the spring elements are accommodated in a corresponding arrangement with the through openings of the base plate of the centering module. B. via corresponding solder lugs with individual wires of the cable 27 are connected.
  • the metallic housing 25 can be designed, for example, as a resilient metal part, so that firm cohesion between the two parts is made possible by the spring contact pressure and locked by special latching lugs.
  • the metallic housing has 2 lugs which plunge into the centering module.
  • the spring tongues then resiliently rest on these metallic lugs after the plugging process.
  • the break point 21 of the springs there is a good contact point with the metallic connector housing 25 via its leg 22.
  • the break points 4 of the longitudinal web and its broad side parallel to the shielding plate are pressed onto this plate.
