Building entrance box with localized wire potting

A building entrance box providing an interface between a signal transmission media cable having a first plurality of filamentary signal transmission elements and a second plurality of individual filamentary signal transmission elements, the box being divided into a splice chamber receiving the cable and a connector chamber receiving the second plurality of individual filamentary signal transmission elements, and wherein a connector field is disposed in the connector chamber to which the second plurality of individual filamentary signal transmission elements is terminated and a third plurality of individual filamentary signal transmission elements extends from the splice chamber to the connector chamber, with each of the third plurality of individual filamentary signal transmission elements being terminated at one end to the connector field and at the other end to a respective one of said first plurality of filamentary signal transmission elements, the box comprising:

• a housing having a substantially planar base wall adapted for mounting to a support and a plurality of substantially planar surrounding walls each substantially perpendicular to said base wall so as to define an open enclosure containing said splice chamber and said connector chamber, said base wall being formed with a recess means open to said open enclosure;
• a substantially planar cover plate mounted within said open enclosure spaced from and parallel to said base wall and disposed over said connector chamber, said cover plate having said connector field mounted thereon with terminations for said second plurality of individual filamentary signal transmission elements being on the side of said cover plate away from said base wall and terminations for said third plurality of individual filamentary signal transmission elements being on the side of said cover plate facing said base wall;
• a separator plate secured transversely to said cover plate and extending toward said base wall to separate said splice chamber from said connector chamber, said separator plate having a portion extending into said recess means to a depth less than the depth of said recess means, said recess means extending on both sides of said separator plate portion;
• and
• potting material in said recess means to a height less than the depth of said recess means but sufficient to contact said separator plate within said recess means;
• wherein said third plurality of individual filamentary signal transmission elements are routed between said splice chamber and said connector chamber in said recess means under said separator plate and the potting material forms a moisture impervious seal between said splice chamber and said connector chamber within said recess means.
