Abstract
A filter insert (40) includes filters (43) having electrodes (48, 60) and contacts (54, 64) axially, mechanically engaging contact post members (28) of a connector (20) to provide filtering extending between signal and ground conductors in the form of connector contacts to filter unwanted signal frequencies. An alternative insert (68) includes filters (69) having slotted beam elements (78) that engage post members (28) from a side thereof with a common ground bus (90) tying the filters to ground. A further alternative insert (108) provides contact elements (116) connecting filters (103) to signal and ground conductors in the form of the wires (104) of a cable (102). The contact elements (54, 64, 78, 116) of the inserts (40, 68, 108) bite into the signal and ground conductors or contacts of a connector or a cable to provide a solderless interconnection of the insert. Filters, including dielectric elements (56, 86, 126,) and inductive elements (44) are contemplated to provide C, LC and pi-filters.
