Abstract: A circuit board connector extension (10) comprising a body (16, 18) made of plastic and able to be attached to a circuit board, with first and second groups of contacts (26, 27) which each have one connecting end (32) for contacting conductor tracks on the circuit board and one plug-in end (28) for contacting contacts of a connector piece, the connecting ends (32) of the two groups of contacts (26, 27) being arranged on one and the same side of the body (16, 18), whereas the plug-in ends (28) of the first group being arranged on a side of the body (16, 18) different from that where the plug-in ends (28) of the second group are arranged.

Abstract: In order, to transmit differential signals between two printed boards, there is provided a printed board connector 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. 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.
