ABSTRACT:
An airtight, watertight, self-contained housing for buried communication lines, such as telephone lines comprising a main cable and service wires, includes a waterproof housing having a base, a ground stake for installing the housing in the ground, separate compartments formed in the housing below the base to separately receive main cable and service wires, a sealed inner splice chamber above the base, and a sealed outer terminal chamber above the base for enclosing the splice chamber and for containing a terminal block. Main cable passes through the base into the splice chamber which includes a support, an elastomeric seal forming a watertight seal between the main cable entering the splice chamber, and an opening to the chamber through the support. A waterproof inner cover joined to the support by a watertight seal forms the sealed splice chamber. The remaining area of the base has separate, removable screw-threaded plugs with O-ring seals to corresponding holes in the base, each for receiving a corresponding service wire. A service wire is installed by removing a sealed plug, passing the service wire through the hole for connection to the terminal block, and forming a watertight seal around the service wire with an elastomeric grommet. A waterproof outer cover is joined to the base by a watertight seal to form a sealed outer terminal chamber that encloses the terminal block and the sealed splice chamber. Another embodiment of the invention provides a terminal for service wire without use of the sealed inner splice chamber.
