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.
Abstract:
A communications connector assembly comprising a jack configured to mate with at least two different types of plugs. The jack comprises a wire board having first and second signal processing circuits thereon. When a first one of the different types of plugs is mated with the jack, the first signal processing circuit is activated. When a second one of the different types of plugs is mated with the jack, the second signal processing circuit is activated. The first signal processing circuit of the connector assembly includes crosstalk compensation circuitry. The first and second signal processing circuits constitute separate signal paths on the wire board. Thus, when the first plug is inserted into the jack, the signal is operated on in accordance with the configuration of the first signal processing circuitry and when the second plug is inserted into the jack, the signal is operated on in accordance with the configuration of the second signal processing circuitry.
Abstract:
A selectable compatibility electrical connector assembly has a high performance plug for mating with the jack to form a high performance electrical connection or to provide switching among various circuit elements to change the transmission characteristics of the assembly. The jack is adapted to receive low performance plugs and has a plug stop therein for limiting the depth of insertion of the low performance plug into the jack. The plug of the invention has an elongated notch in its front end which is designed to clear the plug stop for insertion of the plug to a depth greater than that of the low performance plug. The jack has first and second longitudinally offset latching stubs for latching both the low performance and the high performance plug at their proper insertion depth. An embodiment of the jack has a reciprocating switch assembly adapted to be actuated by the high performance plug when inserted to its proper depth in the jack.
Abstract:
A selectable compatibility electrical connector assembly has a high performance jack and a high performance plug for mating with the jack to form a high performance electrical connection. The jack is adapted to receive low performance plugs and has a movable member therein for altering the transmission loss characteristic of the connector by introducing or removing circuit elements into or from the connector circuit depending upon whether a low performance plug or the high performance plug is inserted in the jack. The plug is adapted to be inserted into a low performance jack and has a movable member therein for altering the transmission loss characteristic of the connector by introducing or removing circuit elements into or from the connector circuit depending upon whether the plug is inserted into or removed from a low performance jack.
Abstract:
An electrical connector, comprising an insulating housing, a plurality of conductors mounted within the insulating housing in at least two rows of aligned pairs, a first compensation section which provides a first crosstalk compensation, and a second compensation section which provides a second crosstalk compensation. A first end portion of each conductor is adapted to electrically connect with contacts of another connector while a second end portion of each conductor is adapted to electrically connect with an electrical device such as a printed circuit board. The first compensation section is located within the insulating housing with the conductors being arranged therein in an orientation to provide the first crosstalk compensation. The second compensation section further is located within the connector and typically comprises a multi-layered circuit board.
Abstract:
A selectable compatibility plug has a substantially hollow housing member and a plurality of contact members extending from a cable connection end to a connector end. A movable circuit member is contained in the housing for translational movement, the circuit members having circuit components on a surface thereof that is in contact with the contact members. Actuator means for moving the circuit member from a first position to a second position is mounted to the circuit member and adapted to be actuated when the plug is inserted in a low performance jack to cause the contact members to contact certain ones of the circuit elements.
Abstract:
A selectable compatibility electrical connector assembly for use in a high performance connection has a plug and a jack, which mate together in the high performance mode, but each of which has contained therein a printed wiring board having circuitry thereon that converts either the plug or the jack to a low performance connector component when used with a low performance mating component. Both the plug and the jack have actuator members which respond to the mating of a low performance component to introduce the printed wiring board or other source of capacitance into the circuit.
Abstract:
A communication jack assembly suitable for high data rate applications, includes a wire board having conductive paths that extend between a jackwire terminal region at a first portion of the board and a wire-connection terminal region at a second portion of the board. A number of spring jackwires extend through the jackwire terminal region, to connect with a communication plug when placed in the jackwire terminal region. The jackwires connect at one end to corresponding conductive paths on the wire board, and the conductive paths form a part of at least one communications signal path when the plug is connected to the jackwires. The conductive paths may be configured to compensate for crosstalk otherwise developed in a signal path once the plug is mated with the jack. A dielectric terminal housing is formed to protect the wire-connection terminal region on top of the wire board, and a cover is formed to protect the connection terminal region on the bottom of the board. The wire board is captured between the housing and the cover when the housing and cover are joined to one another.
Abstract:
An apparatus, preferably plastic, is configured to be attached to a wall face plate, for example, a face plate for a telephone jack, an electrical power outlet, coaxial jack, fiber optic port, etc., and is configured to display information, such as an identification or extension number. The information display apparatus has a housing with a display face that receives and supports an information panel for displaying the information. A transparent cover is placed over the information panel. The display face can be angled to permit viewing of the information at a vantage point above the wall face plate. The apparatus is attached to the exterior face of the wall face plate by attaching the housing to a screw shaft associated with a face plate screw or by adhering the rear side of the apparatus to the face plate with an adhesive material, including for example, an adhesive foam tape.
