An improved keyboard, and a data terminal incorporating same, is disclosed. The present keyboard advantageously includes a keyboard membrane having, on an upper side, a plurality of raised regions upon which character designators can be placed. A plurality of upper key members are disposed on a lower side of the keyboard membrane. Each upper key member is advantageously structurally adapted to return itself, after removal of an actuating force, to an unactuated position. The raised regions on the upper side, and the upper key members on the lower side of the keyboard membrane are advantageously molded from a single elastomeric layer, thereby replacing hundreds of parts in conventional computer-style keyboards using sliding-plunger type key mechanisms. A plurality of lower key members are disposed on a circuit board underneath the keyboard membrane. The lower key members are structurally adapted to prevent ârock overâ when a user depresses a raised region somewhat off-center.
Communication Jack Connector Construction For Avoiding Damage To Contact Wires

International Classification:
H01R 2400
US Classification:
439676
Abstract:
A communication jack connector includes a wiring board having a front region, and a number of contact wires for engaging and making electrical connections with corresponding terminals of a conforming plug connector. The contact wires have free ends formed to be deflected resiliently in a direction toward the front region of the wiring board when engaging the plug connector. At least one clearance opening is formed in the wiring board at a location where the free end of a corresponding contact wire would otherwise contact an upper surface of the board when deflected by the plug connector. The clearance opening is dimensioned so that part of the free end of the contact wire deflects into the opening a certain distance from the upper surface of wiring board while the contact wire maintains sufficient resilient force to connect electrically with the corresponding terminal of the plug connector.

Abstract:
A connector assembly for connecting wire leads of a first cable to corresponding wire leads of a second cable. A terminal housing structure has a first base, and a second base facing opposite to the first base. First pairs of connector terminals are configured to connect with pairs of wire leads of the first cable, and second pairs of connector terminals are configured to connect with pairs of wire leads of the second cable. A wiring board captured between the first and second bases has sets of conductive terminal openings at corresponding locations in the board. The first pairs of connector terminals are mounted on one side of the board in first pairs of terminal openings, and the second pairs of connector terminals are mounted on the opposite side of the board in second pairs of terminal openings which are electrically connected to the first pair of openings. The sets of terminal openings are spaced apart sufficiently to avoid cross-talk between the pairs of connector terminals.

Method For Forming Precision Clockplate With Pivot Pins
Methods are disclosed for producing a precision clockplate with rotational bearing surfaces (e. g. pivot pins). The methods comprise providing an electrically conductive blank, conventionally machining oversize features comprising bearing surfaces into the blank, optionally machining of a relief on non-bearing surfaces, providing wire accesses adjacent to bearing surfaces, threading the wire of an electrical discharge machine through the accesses and finishing the bearing surfaces by wire electrical discharge machining. The methods have been shown to produce bearing surfaces of comparable dimension and tolerances as those produced by micro-machining methods such as LIGA, at reduced cost and complexity.
Transmission Media Patch Panel Modular Cabinetry System
A transmission media patch panel modular cabinetry system for interconnecting transmission media includes at least one patch panel having a plurality of jacks mounted thereto with each of the jacks being configured to mate with a patch cord. First and second closet modules are attached to at least one of the patch panels. Each of the closet modules preferably incorporate an upright, a raceway, and an access channel, with each of the raceways formed adjacent at least one of the patch panels. The access channels, which are formed between the uprights, and the raceways are sized and shaped to pass transmission media therethrough. Doors for selectively providing access to the raceways also can be provided.
A patch panel with pivoting bracket assembly is provided which reduces the tendency for optical fiber patch cords to entangle or snarl in front of the couplings of the patch panel. In a preferred embodiment, the patch panel incorporates a plurality of couplings, with each of the couplings configured to optically communicate with an optical fiber cable. Each of the couplings is moveable between a patching position and a stowed position so that, in the patching position, each of the couplings are configured to receive a patch cord connector in a first direction, thereby allowing the patch cord to optically communicate with an optical fiber cable. In the stowed position, the cables of patch cords engaging the couplings are directed toward the mounting surface in a second direction. Preferably, the first direction and the second direction are oriented toward the mounting surface. A method aspect of the invention is also presented.
