Abstract

An assembly comprising a cable terminator comprising a wire guide, a cube shaped securing cap comprising an open end for installation over the wire guide, and pairs of piercing contacts for piercing respective conductors of the cable. When assembled, an outer end of each of the piercing contacts is exposed on an outer surface of a respective securing cap sidewall. The assembly also comprises a coupler connector comprising one of a modular (for example RJ-45 compatible) socket or a modular (for example RJ-45 compatible) plug, a rearward surface comprising a cable terminator receiving socket, wherein pairs of contacts are exposed along at least one side wall of the socket, and further wherein each of a plurality of the tines in the modular socket or the terminal contacts of the plug is interconnected with a respective one of the contacts. When the cable terminator is inserted into the cable terminator receiving socket, each of the piercing contacts comes into contact with a respective one of the contacts, thereby interconnecting each of the tines (or each of the terminal contacts) with a respective one of the conductors. A back-to-back connector is also disclosed.
