  • Patent number: 4414426
    Abstract: An aerial terminal has a housing divided into back and front compartments by a dividing wall which has a zig-zag formation from top to bottom. A top section of the dividing wall is set forward from a bottom section and a row of apertures is formed in each section. In a preformed arrangement the apertures are oblong and inclined towards each other in pairs. Terminals having shanks fitting in the apertures have transverse holes orientated by the apertures, to be also inclined towards each other in pairs. Shrouds surround the terminals and a channel in each shroud acts to guide a drop-wire conductor into the related terminal hole. The conductor is fastened by a screw in the front of the terminal. Conductors of a stub cable are attached to the rear portions of terminals extending into the back compartment, and the back compartment is filled with potting compound, which holds on a back cover. A front cover clips on to close the front compartment.

  • Patent number: 4390744
    Abstract: A fixed count terminal provides an enclosed housing for the connection of service wires to telephone conductors contained in a communication cable. The fixed count terminal has a support bracket which is clamped to a support strand portion of the communication cable with a mounting bar extending between the points whereat the support bracket is clamped to the support strand. A cable portion of the communication cable is clamped to the support bracket by Z-shaped brackets and ground clamps and a tension bar extends between the Z brackets. A barrier wall divides the fixed count terminal into terminal and cable compartments and has a plurality of breakaway partitions which can be removed so that terminal modules may be positioned on the barrier wall. A base is also secured to the support bracket at the bottom of the barrier wall and has grommeted openings through which the service wires may be extended into the fixed count terminal and coupled to conductors in the communication cable via the terminal modules.

  • Patent number: 4346254
    Abstract: An electrical current of potential is fed to or measured in test leads associated with underground piping, casings and the like through the use of a cathodic test station for flushing mounting in the ground. The test station includes a hollow cylindrical housing having a flanged upper end and an implanted lower end receiving test leads and anchored in the ground by a bar extending therethrough and by ribs projecting radially from the outer surface of the housing. A carrier forms an airtight pocket within side walls projecting from a solid end wall having a flange extending outwardly for recessed support on a shelf in the flanged upper end of the housing. A clamp within the airtight pocket of the carrier supports a terminal block. In one form, the clamp is produced by protrusions from the side wall of the carrier and in another form, a clip extends across the face of the end wall of the carrier. Ends of the clip are spaced from the end wall to support a mounting wall of a terminal block member.
