Abstract
A sealed electrical connector has a housing receiving terminated conductors therein, for mating to a corresponding connector. A camming member is latched to the rear of the housing with bores therethrough through which the conductors extend. Wire seals are disposed between the housing and the camming member around each conductor. A sequential latching provides a first or open position for the camming member which allows for insertion of the terminated conductors through bores of the camming member, through respective wire seals and into respective passageways of the housing wherein the terminals are seated. The camming member is then moved axially forward to a second or closed position which cams against the rear sections of the wire seals and urges and deforms them radially inwardly against the conductors so that a pressure-resistant seal is formed between the conductor, the wire seal, and the camming member. Several types of wire seals are usable with the sealed connector. A latching system for sequential latching of the housing member and camming member has two axially spaced projections on the housing which latch into a slot behind a collar in a first latching and a second latching upon urging the housing and camming members together.

16. A camming member for a sealed connector assembly having a housing member with a plurality of terminal-receiving cavities extending axially therethrough with a wire seal positioned in a rearward section of each said cavity to receive therethrough a terminated conductor associated with said wire seal to be secured in said cavity forwardly of said wire seal, comprising a rigid article including:
-
