Abstract
A housing that includes a cup shaped member and a cover carries a printed circuit board through a plurality of posts. Openings in the housing permit lead wires to be fed to the printed circuit board. The lead wires are leak tightly sealed in the openings by way of shouldered plugs which carry the lead wires. The plugs are sealed with respect to the housing through pliable sealing rings and E-rings secure the plug axially at their shoulders. Locator tabs insure that the plugs engage the openings in a proper orientation. The cover of the housing is sealed with respect to the cup shaped member through a sealing ring carried in a groove of the cup shaped member with pressure being applied through an interference fit with the ring. A leak tight window in the housing permits viewing from the outside. The shouldered plug holding the window is sealed with respect to the housing by a sealing ring and is held axially by the plug being threaded to the housing. The housing has a hollow center post which permits passage of a cable. The center post is sealed to the housing by a sealing ring. The assembly includes an adapter that permits an opening in the housing to be receptive to conduits of two different diameters.
