Abstract

A high-density electrical connector filtering arrangement includes a dielectric insert having a passage for an electrical contact, a second parallelly extending passage in which a chip capacitor is placed, and a ground plate extending transversely to the contact and through which the contact passes without electrical connection thereto. The live electrode of the chip capacitor is electrically connected to the contact via an integral tab extending from the contact in a direction transverse to a longitudinal direction of the contact, and parallel to the ground plate, the chip capacitor being biased against the tab and electrically connected to ground by a resilient finger or extension having a distal end displaced from the ground plate in a direction parallel to the contact axis and having a ground electrode engaging surface which extends transversely to the contact axis.

Claims

1. A capacitive filtering arrangement for an electrical device, comprising:

an electrical signal contact having a principal longitudinal axis extending between mating ends of the contact and a tab extending from the contact transversely to the longitudinal axis of said contact;

dielectric retention means for supporting said contact in said electrical device and including a contact passage extending therethrough, said contact being located in said passage;

a ground plate having a principal plane extending transversely to said longitudinal axis of said contact and an aperture through which said contact extends without electrically contacting the ground plate,

wherein said dielectric retention means includes a component passage therethrough having a central axis parallel to said longitudinal axis, and said ground plate includes an extension having a distal end displaced from a principal plane of the ground plate in a direction parallel to said longitudinal axis, and

further comprising an electrical component positioned in said component passage and having planar electrodes at opposite ends thereof of a principal axis of said component, one electrode of said component electrically engaging said distal end and the other electrode engaging said tab such that said component is supported by said dielectric retention means and said principal axis of said component is parallel to said longitudinal axis of said contact.
