Abstract: A connector assembly includes a connector body defining a cylindrical terminal cavity, an elongate conductor, such as an electrical cable, having one end terminated within the first terminal cavity, and a cylindrical first seal axially surrounding a portion of the first conductor. The seal defines a compliant primary sealing ring that is in compressive contact with an inner wall of the terminal cavity. The first seal further defines an elongate frustoconical sleeve. The connector assembly also includes a seal retainer that is attached to the connector body. The seal retainer defines an elongate frustoconical retainer cavity configured to receive first sleeve. At least a portion of the sleeve is in compressive contact an inner surface of the retainer cavity.
