Abstract

An electrical connector for transmitting data signals between the insulated conductors of a first data cable and corresponding insulated conductors of a second data cable, including a socket shaped to at least partially receive a plug of said first data cable; a plurality of insulation displacement contact slots shaped to receive end sections of the conductors of the second data cable; a plurality of electrically conductive contacts including resiliently compressible spring finger contacts extending into the socket for electrical connection with corresponding conductors of the first cable; insulation displacement contacts seated in corresponding insulation displacement contact slots for effecting electrical connection with corresponding conductors of the second data cable; and mid sections extending therebetween; and a plurality of capacitive plates coupled to respective ones of said mid sections of the contacts by electrically conductive stems, wherein the capacitive plates are arranged side by side and extend in a substantially common direction.

Claims
