Electrical Connector Assembly With Printed Circuit Board Layout

US Patent:
5281154, Jan 25, 1994
Filed:
Nov 24, 1992
Appl. No.:
7/981150
Inventors:
Joseph D. Comerci - Elmhurst IL
Burke J. Crane - Lombard IL
Robert DeRoss - Naperville IL
James K. Hollomon - Virginia Beach VA
Preston B. Johnson - Virginia Beach VA

Assignee:
Molex Incorporated - Lisle IL
International Classification:
H01R 1366
US Classification:
439107
Abstract:
An electrical connector assembly includes a pair of spaced receptacle modules mounted to a first printed circuit board which is electrically coupled to a second printed circuit board spaced from and generally parallel to the first printed circuit board. A conductive ground plate is electrically coupled between the printed circuit boards and mechanically supports the circuit boards in their spaced generally parallel relationship. The ground plate is disposed perpendicular to the first and second printed circuit boards forming two separate compartments between the first and second printed circuit boards to provide electromagnetic interference isolation between the compartments. An electrical component such as transformer may be mounted on one side of the ground plate between the spaced generally parallel printed circuit boards, and the ground plate provides a heat sink for the transformer. A third printed circuit board may be mounted on the side of the ground plate opposite the transformer and electrically coupled to the transformer through the ground plate.
