Patent attributes
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′). The multi-layer circuit board (51) according to the invention is characterized by blind boreholes (60a, 60b-60′a, 60′b) that terminate in different conductor levels (71-71′) of the multilayer circuit board (51) for deliberately contacting the terminal pins (53a, 53b-53′a, 53′b) with conductors (52a, 52b; 72a, 72b-72′a, 72′b) of the multilayer circuit board (51) provided in different conductor levels (71-71′).
