As shown in Figure 8 is, the top of the cover plate 2 closes flush with the tops of the side walls 25, 26, 27 and 28 of the Connector brackets. The inside outline of every breakthrough 41 thus corresponds to the outer contour of a connector holder 17, 18, 19 and 20 of the cable plate 1. At the edge of the Openings 41 of the cover plate 2 are arranged contact springs 40, located on the outside of the side walls of the Support the connector brackets if the cover plate 2, as shown in Figure 8, placed on the cable plate 1 is.

The contact springs 40 make a pronounced ground contact or ground contact between the cover plate 2 and the cable plate 1 ago. At the edge area of the openings 41 can, as shown in FIG. 8, circumferential webs 42 be formed by the underside of the cover plate 2 protrude vertically and point to the cable plate 1 if the Cover plate 2, as shown in Figure 8, on the cable plate 1 is attached. The webs 42 increase the potential Contact area for the contact springs 40 between the Cover plate 2 and the outer outline of the connector holders 17, 18, 19 and 20 of the cable plate 1.

The cover plate 2 has sections 39 which are the branch area 16, where the individual wire pairs or wires come from the cable 7, and also all access areas or access openings the recordings 12, 13, 14 and 15 over the entire area at the top of the side walls of the connector holders Cover 17, 18, 19, 20. So that is the individual Wires or wire pairs 73, which are in the receptacles 12 are inserted, or the entire branch area, where the wires branch off from the cable, shielded on all sides. Disruptive Radiation of electromagnetic energy to the outside is avoided by the all-round shielding.

In FIG. 9, one for executing the cover plate 2 is the FIG. 8 alternative embodiment, namely the cover plate 2.1, shown. This cover plate 2.1 in turn has shielding sections 39.1, which in turn all access openings 30 of the Recordings 12, 13, 14, 15 and also the branch area 16 of the Cover cable plate 1. However, sections 39.1 are in the execution according to Figure 9 lowered so far that it rest on the top of the side walls of the recordings, if the cover plate 2.1 is placed on the cable plate. At extend the design of the cover plate 2 according to Figure 8 the shielding sections 39, however, at the level of Top of the connector brackets. The execution of the Cover plate 2.1 according to Figure 9 has the advantage of an improving Shielding especially with regard to crosstalk between individual wire pairs.

As can be seen in FIG. 8, the cover plate 2 a printed circuit board 3 is used, which is from the printed circuit board 3 protruding pin contacts 50 and 51 in the connector 5 engage for contacting, and a connection unit 6 has, which is contacted with the circuit board 3.
