Elektrischer Verbinder mit programmierbarem Schaltungsplatten-Filter

摘要

An apparatus and method for filtering and grounding individual electrical circuits in an electrical connector is disclosed. The electrical connector is based on standard configurations, such as a printed circuit board header 10 having a standard footprint. A filtering subassembly includes a programmable filter printed circuit board 16 to which surface mount components 56, 66 are soldered. Printed circuit board terminals, such as right angle printed circuit board pins 14 are inserted in plated through holes 38 and electrical connection is established intermediate the ends of the terminals. A solderless compliant pin section 30 can be used. Capacitors 56 can be selectively used to filter certain individual circuits or lines and zero value resistors 66 can be used to ground other lines. These surface mount components are preferable loaded using programmable pick and place equipment and are soldered between pin surface mount pads 44 and adjacent grounded surface mount pads 46. The grounded pads are commoned to a shield layer 52 on one side of the printed circuit board and a peripheral ground strip 40 on the other side so that the board can be mounted in two opposite orientations.
