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 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 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:
In a facility for conveying PWBs in a path of travel, two stop/clamp devices are magnetically clamped along the path to be spaced in its length and to be within the path width occupied by the traveling board. Each of the devices has stop and clamp elements shiftable as a unit between out positions at which they are disposed in the path and in positions at which they and the rest of their device do not interfere with the travel in the path of the boards. When in the out position, the leading device is adapted to stop the travel of such a board, and both devices are then selectively operable to grip and then release the stopped board. Sensors on the leading device are used to detect the presence of a board near to and at such device. A computer is responsive to such sensors and is used to produce a desired sequence of operations of such two devices and of other units.

Each interface may also include, as a routine matter of design choice, electronic devices, circuits, connectors, etc., to provide for additional functionality of the interface. The modular jack receptacle provides increased flexibility in diagnostic and test capability for a particular communication line from a Central Office (CO) to a customer premise location and simplified replacement of electronic devices installed in series with a communication line.
Abstract:
A network interface device includes a base, a cover and a circuit board secured in the base. The circuit board includes terminations for input and output communication lines. Each pair of input and output communication lines corresponds to a single standard telephone line, a high speed data line or other type of line. The communication line terminations may be implemented as insulation displacement connectors, and the cover may include projections on its inner surface such that closing the cover also closes the insulation displacement connectors on the circuit board. For each communication line, the circuit board may include a subscriber bridge which establishes a breakable connection between the input and output line terminations via traces in the circuit board. In fixed wireless, fiber-to-the-home (FTTH) and other similar applications, the circuit board may also include terminations for input and output power lines, and the base and cover may be extended to accommodate an uninterruptible power supply. The power supply supplies the input power line to the corresponding termination on the circuit board, and the output power line is supplied to a power input of a remote unit in a fixed wireless system or other electronic unit external to the network interface device. The circuit board may also include power protection circuitry for protecting against surges on the input and output communication and power lines.

An assembly includes an enclosure and a device for storing fiber slack. The device has a pair of spool portions on opposite sides of the device. Each spool portion is shaped so that fiber slack can be wound back and forth between the two spool portions. The device is pivotally mounted within the enclosure, so that the pair of spool portions can be accessed by pivoting the device. Each spool portion may have a semicircular shape. Each spool portion has a radius at least as large as a minimum bend radius for a fiber to be stored on the device. A length of a fiber portion extending between the pair of spool portions is substantially greater than a perimeter of one of the spool portions. The device has top and bottom U-shaped channels connecting the tops and bottoms of the spool portions, respectively. The pair of spool portions and the top and bottom U-shaped channels form an elongated spool for storing fiber, the elongated spool extending around three sides of the device. The enclosure has a pin or rod mounted in it. The device has a bore extending through it, for receiving the pin or rod, to pivotally mount the device in the enclosure. A splice holder may be mounted within the enclosure.
