Abstract:
Capacitive crosstalk compensation coupling is achieved in a communication connector by the use of a capacitor compensation assembly. The assembly includes a housing constructed to be associated with a communication connector having elongated terminal contact wires. One or more crosstalk compensation capacitors are supported in the housing. Each compensation capacitor includes a first electrode having a first terminal, a second electrode having a second terminal, and a dielectric spacer is disposed between the first and the second electrodes. The terminals of the electrodes are exposed at positions outside of the housing so that selected terminal contact wires of the connector make electrical contact with corresponding terminals of the compensation capacitors to provide capacitive coupling between the selected contact wires when the contact wires are engaged by a mating connector.
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.
Abstract:
An electrical contact with an insulated wire conductor is established by defining a wire passage in a connector housing to receive an insulated wire conductor, and capturing a contact member having an electrically conductive hook portion in the housing. An end of the hook portion projects into the wire passage. When an insulated wire conductor is fed into the passage, insulation on the conductor slides along the hook portion of the contact member. Upon withdrawing or displacing the conductor a certain distance relative to the hook portion, an end of the hook portion engages and pierces the insulation on the conductor to make electrical contact with the conductor.
Abstract:
A protective hood for a faceplate which has one or more couplers therein for receiving electrical and/or optical fiber connectors has an elongated substantially hollow body. The body has a U-shaped open end and a flat closed end, and a sloping or angularly disposed planar surface extending from adjacent the open end downwardly to the closed end. The body has interior extending flanges adapted to fit within L-shaped track forming members on the faceplate to permit up and down movement of the hood, and an interior stop member for limiting the downward movement to define a closed position.
Abstract:
A communication connector assembly that incorporates crosstalk compensation. A number of compensation coupling contacts, e.g., conductive pads, stiff wires or plates, are mounted on a front edge region of a wire board that supports a number of terminal contact wires. Compensation elements associated with the wire board are connected to the contacts and are selected to produce, e.g., capacitive crosstalk compensation coupling. The terminal contact wires have connecting portions for contacting corresponding terminals of a mating connector along a line of contact. Free ends of the contact wires, ahead of the line of contact, are formed to deflect toward the wire board and to connect with the compensation coupling contacts on the board when engaged by the mating connector. The compensation coupling is therefore effective at the line of contact with the mating connector. In the disclosed embodiments, the assembly is incorporated in a modular jack connector.
Abstract:
An upgradeable communication connector for use in wired telecommunication networks. The connector has a connector housing with an upgrade component passage for receiving an electrical upgrade component having at least one electrical contact terminal. A number of electrically conductive connector terminals are supported by the housing. The connector terminals have first end portions for contacting a mating connector, and second end portions for making electrical connections between the connector terminals and outside circuits. At least one of the connector terminals has a contact portion in the region of the upgrade component passage for electrically contacting a contact terminal of the upgrade component when the component is within the component passage.
Abstract:
A terminal housing assembly and terminal arrangement for a wire board, suitable for use with solderless mountable connector terminals. A terminal housing body has a base wall placed on a wire board at a wire connection terminal region of the board. The base wall has a channel grooved in its bottom surface for receiving base portions of a number of connector terminals on the wire board. The housing body has a row of terminal slots that open into the channel to receive wire connecting portions with the terminals, and the base portions of the terminals form shoulders that protrude a certain distance from the wire connecting portions. The housing body includes partitions between the terminal slots, wherein the partitions have bottom parts defining a base of the channel for confronting the shoulders of the terminals, and for restraining the terminals from being pulled out from terminal openings in the wire board while outside wires are being connected to and disconnected from the terminals.
Abstract:
A jack frame includes a jack frame block having a front surface, a pair of side surfaces and a top surface. The front surface has a plug opening with a plug axis along which a plug connector can be inserted to connect to the jack frame block. The front surface is dimensioned to be received in a jack opening in a face plate, and the inner periphery of the jack opening is defined in part by a pair of side walls and a top wall. The top surface of the jack frame block has a first surface portion that extends at a first angle relative to the plug axis of the plug opening in the block's front surface, and a second surface portion that extends at a second angle relative to the plug axis. Either the first or the second surface portion can be aligned with the top wall of the jack opening, so the frame block can be mounted on the face plate with a desired orientation depending on which one of the first and the second surface portions is aligned with the top wall of the jack opening. Engagement members on the frame block are arranged to engage walls of the jack opening when the frame block is mounted in the desired orientation, to limit movement of the frame block relative to the face plate.
Abstract:
A storage spool adapted to have excess optical fiber or wired lengths wound thereon consists of a cylinder having a curved outer surface on which the fibers are to be wound. A mounting arm extends from a separating wall portion on the curved surface and has a mounting latch member on its distal end. The arm has an arcuate fiber guide portion for guiding the fibers onto the curved surface, and retaining means are provided for maintaining the fibers in position on the curved surface of the cylinder.
