A shield is provided that blocks high frequency EMI (electromagnetic interference) from reaching circuitry that is connected to pins of a filter connector. The filter connector includes a plurality of pins (12) that extend through holes (92) in first boards (26), with each pin joined by a solder joint (90) to a signal trace (32, 60) that surrounds the pin hole. Filter components such as capacitors (40), each have one terminal (44) joined to a signal trace and another terminal (42) joined to a ground trace (30), with a gap (62) between the traces. Second boards (75) are provided that each lies facewise adjacent to a first board and that each carries a shield trace (72) that covers the gap between signal and ground traces. The pin-receiving hole in each second board has a circular portion and has a notch (100) therein though which a solder dispenser (102) can fit to dispense solder directly into the space between and on the pin and the signal traces.
A filtered connector which includes a first circuit board assembly (24) with a plurality of pin-receiving holes (32h), a plurality of pins (12) each projecting through one of said holes, a plurality of signal traces (60) each extending at least partially around one of said holes and connected to one of said pins that projects through the hole, a ground plane (30) lying on a surface of said circuit board assembly but spaced from said holes and from said signal traces and leaving gaps (62) between said ground plane and said signal traces, and a plurality of filter components (40) each having a first terminal (42) connected to said ground plane and a second terminal (44) connected to one of said signal traces, comprising:
A filtered connector which includes a dielectric first board (26) with a plurality of first holes (28) that each has an axis (112), a plurality of pins (12) that each projects through one of said first holes, a plurality of signal traces (32, 60) on said first board that each extends at least partially around one of said holes, at least one ground plane (30) on said board, a plurality of filter components (40) each having one terminal (44) connected to one of said signal traces and a second terminal (42) connected to a ground trace (52) that is connected to said ground plane, comprising:
A filtered connector that includes a plurality of pins (12), and a first circuit board (26) with a plurality of pin-receiving holes (28) each receiving one of said pins, a plurality of signal traces (32, 60) each extending at least partially extending around one of said holes and soldered to one of pins thereat, a ground plane (30), and a plurality of filter components (40) each connected to said ground plane and to one of said signal traces and with a gap (54, 62) between said ground plane and each of said signal traces, including:
