Abstract:
A fiber optic pedestal for holding a plurality of fiber optic cable splices having at least one vertically disposed wall including a splice holder intermediate first and second engagement projections. The engagement projections having a surface for engaging fiber optic cable adjacent a splice which does not exceed the maximum bend radius of the cable. The pedestal is preferably formed with a fiber optic cable passageway on the interior of the at least one wall with the engagement projections located on the exterior of the walls. The pedestal further includes one or more radial openings for cable running through the passageway to pass to the first projection, the splice to be held in the splice holder and the continuing cable to engage the second projection and reenter the interior passageway through the one or more openings.
Abstract:
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. In a first embodiment, moisture infiltration is reduced by providing potting material in a transition region between a splice chamber of the box and a connector chamber of the box. In another embodiment, a plastic protector panel is specifically shaped to reduce condensation and to reduce the effects of any condensation. Modular protector panels mounted in the box are automatically grounded when mounted to a conductive chassis plate and are so arranged that input and output wires are isolated from each other. Mounting of stacked boxes in a predetermined alignment is effected by a first embodiment of a bracket assembly having a variable overall length but a fixed horizontal alignment, and by a second embodiment of a bracket which is breakable by an installer to achieve a desired bracket length.

Abstract:
A method of making wiring connections which are protected against environmental conditions. A wire wrap terminal is first coated with a thin film of silicone gel. After the silicone gel has cured, a wire is wrapped around the terminal. The wire displaces the silicone gel as it is wrapped around the terminal. Silicone gel trapped between the terminal and the windings of the wire prevents environmental elements from getting to and degrading the electrical contact interface between the wire and the terminal.
Abstract:
A strain relief for an insulation displacement connector contains a cap section and a base section connected to the cap section at a pivot point. The cap section has at least one wire insertion channel and a first wall. The wire insertion channel has an entrance aperture which is in fluid communication with an exit aperture for passage therethrough in an insertion of an inserted wire. The exit aperture is contained in the first wall. The cap section is pivotally moveable between an open position which facilitates insertion of the wire into the cap section through the entrance aperture and out through the exit aperture, and a closed position. The base section has a side wall and a base hole or depression formed in the base section at the foot of the side wall. The base hole includes a wire stop portion at its bottom. The base hole is disposed such that passage of the inserted wire out through the exit aperture into the open portion of the base hole is limited by abutment against the wire stop portion at the bottom of the base hole. In this orientation, the wire is retained in the base hole at a first orientation which is substantially parallel to the insertion direction of the inserted wire. When the cap is moved into the closed position, the first wall of the cap section forces the wire into contact with the side wall so as to cause the wire to be bent and thus oriented at a wire bend angle in a second orientation. In this second orientation, the wire is restrained in the connector as a result of this forced bend and thereby is strain relieved.
Abstract:
A connector testing system includes a bridge clip having a body and at least one test lead having a fixed end connected to the body and a free end having a projection formed thereon, and a connector having a top portion and a housing having at least one test channel therein. At least one terminal strip is disposed within the connector and a portion of the terminal strip is disposed within the at least one test channel. A flap is connected to the housing for sealing the at least one test channel when the flap is in a first position and for sealing the at least one test channel and securing the bridge clip to the connector at a second position.

A portion of the terminal strip is disposed within the at least one test channel. A first flap is connected to the housing for substantially sealing the test channel when the first flap is in a first position and for sealing the test channel and for biasing the bridge clip test lead against the connector at a second position.
Abstract:
A terminal strip with an integrated strain relief mechanism is deployed in an insulation displacement connector that contains a cap section, a base section including at least one terminal strip, and a latch member. The cap section is movable between an open position and a closed position and has therein at least one terminal strip receiving portion and at least one wire insertion channel for holding a wire. The channel has an entrance aperture for entry of the wire. The open position facilitates entry of the wire into the channel. When the cap section is in the closed position, the terminal strip is contained within the cap in the terminal strip receiving portion. The terminal strip includes a first arm having a first arm recess and a second arm having an offset tab. The latch member is movable between an engaged position and a disengaged position such that when the latch member is in the engaged position, it maintains the cap section in the closed position. When the cap is closed, the wire in the channel is forced upward by the offset tab of the terminal strip causing the wire to bend around the offset tab. This bend in the wire provides strain relief.
Abstract:
A self-sealing pressure valve assembly which eliminates O-rings by providing a tapered annular projection on one side of a wall closely surrounding an opening through which the valve is installed. A complementary engaging projection is provided on a locking member of the valve assembly. In addition, the wall opening and the valve body are tapered on the side opposite the projections. Thus, the projections provide a seal on one side of the wall and the tapers provide a seal on the other side of the wall when the locking member fully engages the valve body, as by threads.
Abstract:
A connector assembly test block for simultaneously verifying the wiring of a plurality of pairs of electrically-conductive connectors in a connector assembly. The test block has a plurality of pairs of electrically-conductive contact members positioned for concurrent conductive contact with the pairs of connectors when the test block is interfaced with the connector assembly. The test block also includes an indicator device conductively connected to each pair of contact members. The indicator devices are responsive to a signal generated when energized. Each indicator device provides a perceptible indication verifying proper wiring of a pair of connectors when conductively connected to a pair of energized connectors.
