Abstract

Abstract An electrical connector comprising a multiple terminal connector body has a sturdy and easily installed end cap that is secured to the connector body for sealing the cable end. The end cap includes a seal chamber that is disposed in a common cavity at the cable end of the connector body and contains a compliant sealing material which seals the open ends of the terminal cavities and encapsulates projecting ends of the electric terminals and trailing portions of the electric cables. The end cap is configured to maintain the integrity of the seal chamber, to permit the electric cables to pass out of the common cavity at the cable end of the connector body, to assure that the electric terminals are properly located in the terminal cavities of the connector body and to provide a strain relief in cooperation with portions of the connector body.
