Electrical device for interconnecting two printed circuit boards at a large distance

摘要

An electrical device ( 100 ) for interconnecting two parallel printed circuit boards at a large distance includes a plug connector ( 1 ), a receptacle connector ( 1 '), and a mating extender ( 2 ) disposed between the plug connector and the receptacle connector. The mating extender includes a subassembly of wafer ( 21 ), a pair of identical caps ( 20 ) disposed on the top and bottom portions of the subassembly of wafer, and a pair of shroud-halves ( 22 ) sliding on the subassembly of the wafer. The subassembly of wafer is made up of a number of wafer modules ( 24 ) parallel with each other. Each wafer module has a wafer support ( 26 ) and a number of contacts ( 28 ) embedded in the wafer support.
