Definitions

  • the invention relates to a device for the electrical connection of shield caps of multipole plugs to the ground potential layer of a wiring board containing a plurality of contact elements perpendicular to it.
  • the shielding cap of a switching cable is attached to the carrier board of an assembly and is electrically connected when the cable connector is inserted via the contact elements to the earth potential layer of an assembly frame.
  • the contact elements are designed on the assembly frame as contact springs.
  • the shielding caps are provided with suitable contact surfaces, which are pressed by the contact springs when the plug is inserted and thus electrically connect the shielding caps to the earth potential.
  • This known device does not have the shortest and therefore the lowest resistance connection between the shielding cap and the earth potential layer of the wiring board. Increased signal processing speeds and thus higher interference fields in the signal lines as well as the increasing number of connector poles require more effective shielding of the connectors and connector strips.
  • the invention has for its object to keep the connection between shield caps multi-pin connector to the ground potential layer of the wiring board short and thus low resistance, and to meet the additional requirements.
  • the contact elements are attached directly to the wiring plate and the spring elements directly to the shielding caps in order to achieve a very short connection between the shielding caps of the multi-pin connector and the wiring plate.
  • the shielding caps can extend to the wiring plate and thus improve the shielding of plug connections.
  • stiffening plates can be provided with a suitable module spacing, as described in patent application P 34 32 367.8.
  • the spring elements are arranged on the outside or inside of the shielding caps. Attaching spring elements to both the outside and the inside of the shielding caps results, for example, in electrical connections to contact meters and stiffening plates and thus leads to even lower-resistance connections to the earth potential layer of a wiring board.
  • the contact blades which are electrically connected to the ground potential layer of the wiring board and to the shielding caps, can be arranged within the plug areas.
  • Contact knives lying outside the plug areas, which are connected to the ground potential layer of the wiring board, can be crimped onto free slots of adjacent multipole plug connections for the latter reasons.
  • 1 to 6 each show schematic sectional views of the structure of shielded plug connections.
  • the exemplary embodiment according to FIG. 1 shows a wiring board 1 with a plurality of contact knives 2, 3 standing vertically on it. On correspondingly arranged contact knives 2 there are multipole module plugs 4 on the assembly side. Between the regions of a suitable spacing there are contact knives 2 for the assembly plugs those contact blades 3 are arranged, which are electrically connected to an existing on the wiring board 1 ground potential layer. Spring elements 5, which are attached to shielding caps 6 of adjacent module connectors 4, resiliently rest on these contact blades 3 on both sides. This fede retti 5 are located on the outside of the shielding caps 6 near the edge of the cap.
  • the approximately semicircular spring elements 5 are pressed against the contact blades 3, whereby the shielding caps 6 of the module connectors 4 are electrically connected to the earth potential layer of the wiring board in the shortest possible way.
  • the shielding cap 6 surrounds the module connector 4 in such a way that it lies flush against the outer surfaces of the module connector 4 pointing in the direction of insertion.
  • the wiring board 1 also contains a plurality of contact knives 2, 3 which are perpendicular to it.
  • contact knives 2 there are multipole module plugs 4 on the assembly side the module connector 4 serve.
  • This centering bar 7 is provided with openings for the contact knife 2.
  • the contact blades 3 electrically connected to the earth layer of the wiring plate 1 are arranged on the wiring plate 1 so that they partially engage in corresponding recesses in the centering strip 7. Those areas of the contact blades 3 which emerge from the outer surfaces of the centering strip 7 which extend parallel to the plugging direction serve as a contact surface for the electrical connection to the shielding cap 8 of the module connector 4.
  • the edges of the shielding caps 8 pointing in the direction of the wiring plate 1 serve as spring elements 9, which are arranged approximately semicircularly inward so that they bear resiliently on the contact blades 3.
  • the shielding cap 8 encases the module connector 4 including the centering bar 7 almost completely.
  • the outer surfaces of the shielding caps 8, which extend parallel to the plugging direction can extend as far as the wiring board 1.
  • FIG. 3 shows a wiring board 1 with a plurality of contact blades 2 standing vertically on it.
  • Stiffening plates 10 are arranged between the contact blade area, each assigned to a module connector 4, which are electrically connected to the ground potential layer of the wiring board 1.
  • FIG. 4 shows an exemplary embodiment for the connection of a cable connector on a wiring board 1 with a plurality of contact blades 2, 3 standing vertically on it. Both the contact blades 2 assigned to the respective cable connector 13 and the ones connected to the ground potential layer of the wiring board 1 are located in position A and E arranged contact knife 3 within the contact knife area of the respective cable connector 13. Between the cable connector 13 and the wiring board 1, a centering strip 14 is inserted, which receives the cable connector 13 approximately form-fitting. The centering bar 14 is provided with openings for the contact blades 2, 3. The distance between the centering bar 14 and the wiring plate 1 results from the fastenings of the centering bar 14, not shown.
  • the cable connector 13 surrounds a shielding cap 15, on the cap edges of which spring elements 16 are designed such that they rest resiliently on those contact blades 3 which are connected to the ground potential layer the wiring board 1 are electrically connected.
  • the cable plugs 13 have corresponding cutouts for receiving the spring elements 16.
  • the approximately semicircular spring elements 16 point in the direction of the adjacent contact blades 3.
  • FIG. 5 shows a further embodiment for the connection of cable plugs to a wiring board 1 with a plurality of contact knives 2, 3 standing vertically on it.
  • Centering strips 18 are inserted between the cable plugs 17 and the wiring board 1, which receive the cable plugs 17 approximately in a form-fitting manner.
  • the centering strips 18 are provided with openings for the contact knife 2.
  • the distance between the centering strips 18 and the wiring plate 1 results from the fastenings of the centering strips 18, not shown.
  • the contact blades 3, which are electrically connected to the ground potential layer of the wiring plate 1, are placed on the wiring plate 1 so that they partially engage in corresponding recesses in the centering strip 18.
  • the wiring board 1 in turn contains a plurality of contact knives 2, 21 which are perpendicular to it.
  • the contact knives 21 which are electrically connected to the ground potential layer of the wiring board 1 are in plug positions A or E of adjacent plug connections which are not provided with contact knives 2 or are kept free cranked.
  • the further design of this exemplary embodiment corresponds to that in FIG. 5.
  • FIGS. 1 to 6 Further developments of the invention can be achieved by combinations of the exemplary embodiments illustrated in FIGS. 1 to 6, in particular with regard to even more effective shielding of plugs by means of several electrical connections from the shielding caps of the plugs to the earth potential layer of the wiring board.
