Abstract: A plug-type element for making contact with a printed circuit board comprises an insulating body. At least one electrical contact which has at least two spring elements is arranged in the insulating body, wherein each spring element has at least one printed circuit board contact (121, 122). In particular, the plug-type element can be a plug-type connector, a relay socket or a safety plug.

Abstract: The invention relates to an assembly of a plug connector and a circuit board (200; 500), the plug connector (100; 400; 800) being arranged on an edge of the circuit board (200; 500; 801), characterized by contact elements (110, 120; 410, 420, 430; 805) arranged in, below, and above the circuit board plane, wherein at least the contact elements (110, 120; 410, 420, 430; 805) arranged below and above the circuit board are bent on the side of the contact elements facing the circuit board (200; 500; 801) in such a way that the contact elements lead from both sides of the circuit board (200; 500; 801) into openings in the circuit board (200; 500; 801) adapted to the contact elements (110, 120; 410, 420, 430; 805) and can be soldered there.

Abstract: The invention relates to a plug-in connection having shielding, in particular a multi-pin, multi-row plug-in connection comprising a male multipoint connector and a female multipoint connector, the plug-in connection comprising signal contacts, which are arranged in a contact pattern of differential pairs and which form a contact group together with an L-shaped shielding element that surrounds the signal contacts, the contact groups being arranged in rows and columns and adjacent contact groups in adjacent columns being offset from each other by a specifiable length dimension in the longitudinal direction of the columns, the plug-in connection being characterized in that the specified length dimension corresponds to approximately half the distance of two adjacent contact groups in a column.

Abstract: The invention relates to a multi-pole plug connector (90) for contacting a multi-layer circuit board (51), comprising a plurality of contact elements (50a, 50b-50?a, 50?b), as well as to a multi-layer circuit board for assembly with a multi-pole plug connector (90), comprising blind boreholes (60a, 60b-60?a, 60?b) for contacting terminal pins (53a, 53b-53?a, 53?b) of the contact elements (50a, 50b-50?a, 50?b) of the multi-pole plug connector (90). The invention further relates to a combination of a multi-pole plug connector (90) for contacting with a multi-layer circuit board (51) and to a multilayer circuit board for assembly with the multi-pole plug connector (90). The plug connector (90) according to the invention is characterized by terminal pins (53a, 53b-53?a, 53?b) that have different lengths for contacting the terminal pins (53a, 53b-53?a, 53?b) with conductors (52a, 52b; 72a, 72b-72?a, 72?b) of the multi-layer circuit board (51) provided in different conductor levels (71-71?).
