ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to electrical connectors and more particularly to modular connectors for use in connecting a daughter printed wiring board to a mother printed wiring board.
2. Brief Description of Prior Developments
In the manufacture of computers and various other electronic assemblies, daughter boards are commonly connected to mother boards by means of a connector having a receptacle having a plastic housing and a first and second face wherein terminals are connected in one face to the daughter board and at the other to a header connected to the mother board. Various arrangements have been suggested to ground such connectors to the mother or daughter boards but such arrangements have tended to complicate the construction of the connector. A need, therefore, exists for simple and inexpensive means for grounding connectors between mother and daughter boards. There is also a need for such a connector which reduces crosstalk and increases band width.
SUMMARY OF THE INVENTION
The shield arrangement of the present invention comprises an external conductive shield and an internal conductive shield. The external shield encloses the electrical connector and has at least one inwardly directed projection. The internal shield at least partially resides within the electrical connector and has at least one feature engaging the at least one projection.
The electrical connector of the present invention comprises: a housing; a plurality of contacts; an external conductive shield; and an internal conductive shield. The contacts extend through the housing. The external shield encloses the housing and has at least one inwardly directed projection. The internal shield at least partially resides within the housing and has at least one feature engaging the at least one projection.
The receptacle electrical connector of the present invention comprises: a housing; a plurality of contacts; an external conductive shield; and an internal conductive shield. The housing has a front face with a plurality of apertures arranged in a plurality of columns. The contacts are also arranged in a plurality of columns in the housing, each contact having a mating end adjacent a corresponding openings. The external conductive shield encloses the housing and has at least one inwardly directed projection. The internal conductive shield at least partially resides within the housing at a location between adjacent columns of contacts, and has at least one feature engaging the projection.
