An electrical connection system includes various devices and structures for improving alien crosstalk performance in a high density configuration. In certain examples, a plurality of insulation displacement contacts of a connector are arranged at angle and oriented to be symmetrical about an axial of the connector. The connector includes a connector housing and a shield cap configured to at least partially cover the connector housing. The shield cap includes a shield wall and an open side that is not closed by a shield wall. The shield wall exposes a portion of the connector when the shield cap is mounted to the connector housing. When a plurality of such connectors are arranged side by side in a high density configuration, the connectors are aligned such that the open side of the shield cap is arranged close to, or abutted to, the shield wall of the shield cap of an adjacent connector.

A wire connection device includes an electrical wire, an insulation displacement terminal and a stress relaxation member. The electrical wire includes a conductor and an insulation coating on an outer periphery of the conductor. The insulation displacement terminal has a slot in which the electrical wire is fitted. The insulation displacement terminal is connected to the electrical wire by both side portions of the slot being in direct contact with the conductor and pressing the conductor elastically and plastically. The stress relaxation member is fitted in the slot of the insulation displacement terminal to suppress deterioration of a stress applied to the electrical wire.
