ABSTRACT:
In an electrical cable having an impervious sheath thereabout defining a space between the cable and the sheath, a breather cap assembly is provided to enable the space between the cable and the sheath to be in free communication with the ambient atmosphere surrounding the sheath, while serving to prevent the ingress of water into the space. The breather cap assembly comprises a nipple which is threadedly secured to the sheath and includes an orifice extending longitudinally therethrough. A slot is provided in the end of the nipple and in communication with the orifice to prevent the orifice from being blocked inside the sheath. The other end of the nipple is threadedly secured to baffle means. The baffle means is a hollow member including an open end disposed furthest away from the nipple means and having a planar baffle staked within the interior of the baffle means and a cup-shaped baffle press fit therein and adjacent the opening. The planar baffle includes an opening coaxial with the orifice and the cup-shaped baffle includes plural openings disposed laterally of the axis of the orifice. The two baffles serve to increase the distance along the interior of the baffle means that water must traverse to reach the orifice and hence enter the sheath of the cable.
