Abstract
Abstract An electrical connector is disclosed in which the insulator thereof contains a plurality of contact passages. A contact retention plate extends transversely across the insulator between its front and rear faces. The plate embodies apertures aligned with the contact passages. Contact retention fingers extend inwardly from the edges of the apertures to engage shoulders on insulative sleeves mounted on the contacts in the passages. The insulative sleeves provide a higher degree of contact-to-contact electrical isolation and, therefore, permit high density contact arrangements.
