Abstract
In an embodiment, a connector such as an edge connector includes a connector housing, a first set of pins configured within the housing and having first ends to couple to corresponding signal lines of a first circuit board and second ends to couple to corresponding signal lines of a mating connector of a second circuit board, and a conductive material adapted to the housing to reduce interference caused by one or more sources of interference. Other embodiments are described and claimed.
Claims16
An edge connector comprising:
- a connector housing formed of a non-conductive material;
- a socket portion included in the connector housing having a first set of pins included within the connector housing and having first ends to couple to corresponding signal lines of a first circuit board and second ends to couple to corresponding signal lines of a mating edge connector of a second circuit board;
- and
- at least one conductive shield embedded within the connector housing to reduce interference caused by one or more sources of interference.
An apparatus comprising:
- a connector coupled to a first circuit board and a second circuit board, the connector including a first plurality of pins to enable signal interconnection and a second plurality of pins to enable ground interconnection;
- and
- a shield located about the connector to shield the first plurality of pins from one or more sources of interference, wherein the shield comprises a plurality of openings, each of the plurality of openings including one of a plurality of fingers integrated into the shield and positioned to contact a corresponding one of the second plurality of pins, the second plurality of pins coupled to a ground plane of at least one of the first and second circuit boards.
A system comprising:
- a first circuit board;
- a connector coupled to the first circuit board, the connector associated with a conductive shield to shield pins of the connector from a source of interference, the conductive shield comprising a frame structure positioned about a terminal end of the connector to substantially surround the pins of the connector, wherein the frame structure comprises a plurality of openings, each of the plurality of openings including one of a plurality of fingers integrated into the frame structure and each coupled to one of the pins of the connector, wherein each of the pins of the connector coupled to one of the plurality of fingers is coupled to a ground plane of the first circuit board;
- a second circuit board coupled to the connector, the connector to interconnect the first circuit board to the second circuit board;
- and
- a voltage regulator coupled to the first circuit board, wherein the voltage regulator is located in close proximity to the connector and comprises at least one source of interference.
