Abstract

In order to transmit differential signals between two printed boards, the invention proposes a printed board connector consisting of an insulating connector housing and disk-shaped modules that contain electric contact elements and are arranged in the connector housing, wherein modules featuring signaling contacts and modules featuring shielding contacts are alternately arranged adjacent to one another. In this case, the shielding module is realized in such a way that signaling contact pairs arranged on top of one another are also at least regionally shielded relative to one another.

Claims

1. A printed board connector for producing direct pluggable connections between printed boards, comprising an insulating connector housing and disk-shaped modules that contain electric contact elements and are arranged in the connector housing, wherein modules featuring signaling contacts and modules featuring shielding contacts are alternately arranged adjacent to one another,

wherein the two respective signaling contacts that form a differential pair are at least regionally separated by a shielding module arranged between the signaling pairs.

2. The printed board connector according to claim 1,

wherein the shielding module comprises a flat shielding contact with plug contacts pointing to the mating side molded thereon, as well as at least one terminal end arranged perpendicular thereto.

3. The printed board connector according to claim 1,

wherein the shielding module comprises a flat shielding contact that is surrounded by an insulating member and plug contacts pointing to the mating side molded thereon, as well as at least one terminal end arranged perpendicular thereto.

4. The printed board connector according to claim 1,

wherein the terminal end of the shielding module is in the form of a part that is about centrally bent out of the shielding contact at a right angle.

5. The printed board connector according to claim 1,

wherein the shielding module is respectively arranged between two signaling contact modules, wherein the right-angled terminal end is arranged between the differential signaling contacts.

6. The printed board connector according to claim 1,

wherein the shielding module features segment-shaped press-on zones that respectively lie of one another.

7. The printed board connector according to claim 1,

wherein the module featuring the signaling contacts is in the form of a disk-shaped insulating member, wherein electric contacts embedded in said insulating member feature fork-shaped springable plug contacts, as well as terminal ends.

8. The printed board connector according to claim 7,

wherein the plug contacts are centrally arranged in the signaling module, namely symmetrical referred to its disk width, and in that the terminal ends are arranged asymmetrically and end flush with an outer peripheral surface of the module.

9. The printed board connector according to claim 1,

wherein the terminal ends are arranged in the signaling module asymmetrically referred to its disk height, wherein a terminal end is arranged in the first quarter and the second terminal end is arranged in the third quarter while the plug contacts are symmetrically arranged in the signaling module referred to the disk height.

10. The printed board connector according to claim 1,

wherein one of two adjacently arranged signaling modules is respectively turned by 180°

about its axis that is oriented in the plug-in direction, wherein this turned signaling module is arranged in the connector housing adjacent to the other signaling module such that the terminal ends are arranged alternately offset by the material thickness of the terminal ends in bores of the printed board.

11. The printed board connector according to claim 1,

wherein two adjacently arranged signaling modules can be respectively inserted into an intermediate space formed by webs that are molded onto the interior of the connector housing.

12. The printed board connector according to claim 1,

wherein a shielding module can be inserted between two respective signaling modules, namely into the vertical space between the opposing webs in the connector housing.

13. The printed board connector according to claim 1,

wherein the connector housing features insertion slots, into which the shielding modules can be inserted.

14. The printed board connector according to claim 1,

wherein the insulating member of the signaling module features a slot that is arranged between the terminal ends.
