Definitions

  • the invention relates to a shielded cable connector for plugging onto a connector, in particular a backplane of a module frame, the cable connector being enclosed by a shield housing.
  • Such a cable connector is e.g. became known through the documents of the German utility model 92 07 674.
  • the shield housing of the cable connector can then be contacted with shield plates which are arranged along the side walls of the cable connector. Lugs are cut out and bent out of the shield walls of the shield housing and protrude into the locking slots of the shield plates. The free cutting and bending out result in openings in the shield housing which impair the shielding effect at very high-frequency cable connectors.
  • the invention has for its object to improve the shielding effect.
  • the development according to claim 2 makes it possible to stabilize the cable connector in a form-fitting manner on the shield plates.
  • At least the two outer mounting projections of the compact sheet metal plate can be easily cut and bent.
  • cutting contours for the inner guide lug and the inner latching lug can be connected to one another in such a way that a simple window shape with smooth, continuous cutting edges results. Care must be taken that at least two of the cut edges are at the same height, so that the window on this side runs in a straight line.
  • the bending radii of the mounting projections can protrude into the slot-like openings, so that the sheet metal plate can lie closely against the shield housing.
  • the enlarged gaps between the mounting protrusions and the shield housing are covered by the curved parts of the mounting protrusions.
  • FIG. 5 is a plan view of the sheet metal plate according to FIGS. 3 and 4,
  • a connector 1 with a connector housing 2 is placed on a backplane 3. These and the connector housing 2 are penetrated by connector pins 4 and form on the side of the backplane 3 facing away from the connector 1, plug contact points for plug-in modules 5, which can be inserted into a module frame, on the back of which the backplane 3 is fastened.
  • the connector housing 2 has on its longitudinal sides side walls 6, along which shield plates 7 extend, which are provided on their inside with contact spring strips 8.
  • the shield plates 7 are attached by means of comb-like protruding pins 9 in bores of the backplane 3 and contacted with ground.
  • the contact spring strips 9 rest against the shield plates 7 and are bulged in their central region towards the side walls 6 and provided with transverse slots between which spring tongues 10 are formed.
  • a shield housing 11 of a cable connector is with its shield walls inserted between the spring tongues 10 and the side walls 6 and contacted with the spring tongues 10.
  • the shielding plates 7 are extended in the plug-in direction beyond the contact spring strips 8 and form on their upper side guide sections which are provided with slot-like openings 12, protrude into the detents 13 protruding from the shield housing 11 and thus prevent the cable connector from being inadvertently pulled out to back up.
  • guide slots 14 are cut out from the insertion side and extend in the insertion direction, into which guide webs 15 projecting vertically from the shield housing 11 are inserted.
  • guide webs 15 there are hook-like projections 16 in their material plane, which extend beyond the base of the guide slots 15 and engage behind the shield plate 7 with little play. They form together with the webs Füh ⁇ approximately hook-like guide lugs 17, which housing the application of shield 11 together with the locking lugs 13 form-fitting manner to the shield plates 7 in 'all coordinate directions hold.
  • the locking lugs 13 and the guide lugs 17 are cut out of a separate sheet metal plate 19 and bent out, which is fastened to the inside of the screen housing 11.
  • slot-like clearances 20 are formed in the shield housing, the
  • Width is approximately equal to the thickness of the plate 19. In this way, the screen housing 11 remains largely closed with regard to its screen effect.
  • FIGS. 3 to 6 show the shape of the sheet metal plate 19 with the guide lugs 17 and the locking lugs 13 in detail. It can be seen that the slot-like opening 20 is only closed by the guide nose 17 with its guide web 15. For reasons of assembly, the hook-like projection 16 engaging behind the screen wall 7 requires the greater length of the slot-like clearances 20, which, however, are covered by the screen wall 7 in this area.
  • FIGS. 5 and 6 show the complete shape of the sheet metal plate 19 with the guide lugs 17 and the latching lugs 13. These protrude through the outer wall of the shield housing 11, the slot-like clearances 20 of which are indicated in FIG. 5 as dash-dotted lines. In each case one of the guide lugs 17 and the latching lugs 13 are punched free along two opposite side edges of the sheet metal plate 19 and bent vertically outwards. In the top view of FIG. 5, the inner mounting projections 13, 17 protrude into a common middle window, from which they are cut free and bent outwards. It can be seen that the slot-like clearances 20 are widened in the region of the radii of curvature, so that the sheet metal plate 19 can lie flat against the screen housing 11.
  • the widened sections of the slot-like openings 20 are covered by the curved sections of the mounting projections 13, 17, so that there are no harmful openings.
  • the remaining contours of the slot-like clearances 20 are closely matched to the cross section of the mounting projections and are thus completely closed by them.
  • the locking lugs 13 and guide lugs 17 are arranged in such a way that they are aligned with their lower edges 21 pointing in the direction of insertion, which simplifies the cut shapes.
