Connector assembly for printed circuit boards.

摘要

A connector assembly for printed circuit boards comprises a first and a second connector part. The first connector part has a first housing of insulating material and having a bottom and two opposite side walls and with male contact elements mounted in the bottom of the housing and arranged in rows and columns and having portions projecting from the bottom of the housing adapted to be inserted into holes of the corresponding printed circuit board. The second connector part has a second housing of insulating material adapted to be inserted into the first housing with an insertion side and with female contact elements mounted in the housing and arranged in a corresponding manner in rows and columns and having portions projecting from a lower side of the housing and adapted to be inserted into openings of the corresponding printed circuit board. A third housing is provided substantially corresponding with the first housing and adapted to be fixed with its bottom on the male contact elements of teh first connector part after mounting said first connector part on the corresponding printed circuit board. In the second housing at least one ground contact plate unit with a cross-shaped cross section is provided, dividing said housing in quadrants with a mutually equal plurality, preferably four, of female contact elements, wherein the ground contact plate unit at the insertion side of the second housing projects from this housing along a distance substantially corresponding with the thickness of the bottom of the first and third housings, respectively. A cross-shaped slot is provided in the bottom of the first and third housings for receiving the ground contact plate unit, said slot dividing the bottom of the housing in quadrants with said plurality of male contact elements.
