TH14271A - Strip filters and their applications in electrical connections? - Google Patents

Abstract

The electrical connection assembly (10) includes at least one signal contact (22) and one grounding structure (16) mounted in a non-conductive housing (12) with a flat outer surface (19). The filter (32) is applied to each signal contact if required and is in the form of a strip of non-conductive material (36) stacked between the wide terminals (34,38), with the strip attached to the outer surface of the housing (14). The non-conductive material is selected from materials of the required thickness and capacitance when measured between the signal and ground terminals (34,38). The method involves electrically connecting the signal and ground terminals to the signal contact (22) and the grounding structure (16) while pressing the strip filter along and across the surface. The outer housing face (19) between the connections for the terminals (34,38) of the filter connected between the signal contacts and the structure is grounded to allow the filter to be placed in the signal path and to help to ground it effectively.
