Abstract: A wire connecting unit for an electrical connector includes a printed circuit board and four pairs of terminals. The printed circuit board has nose and termination areas, and a wire receiving passageway extending along an axis in the termination area. Contact connections are mounted in the nose area. Terminal connections are mounted in the termination area. Conductive paths on the circuit board electrically couple respective contact connections and terminal connections. Each of the terminals has a coupling portion mechanically and electrically coupled through one of the terminal connections, and has a insulation displacement contact portion. Each insulation displacement contact portion is adjacent the wire receiving passageway. The terminals of each pair have spacings between them which are smaller than the spacings between the pairs.

Abstract: A connector for communication systems includes a housing, a plurality of insulation displacement contacts, and front and rear sleds. The housing has front and rear ends and an internal chamber opening on the rear end and defined by housing walls. A plurality of slots extend through one housing wall adjacent its front end. The insulation displacement contacts are mounted in the slots for movement between retracted positions spaced from the chamber and inserted positions extending into the chamber. The front sled is located in the internal chamber adjacent the front end, and has front sled walls defining axial passages through it. Lateral openings extend through one of the front sled walls into the axial passages and are aligned with the slots and the contacts in the housing.
