An optical fiber distribution panel assembly wherein a panel holding fiber connector blocks is pivotably mounted to a base member about a horizontal axis. Fibers exiting an optical switching module supported on the base member are routed up the sides of the panel and terminatd at appropriate ones of the fiber connector blocks. Excess slack fiber is coiled and placed on fiber takeup saddles secured to a panel overlying the connector block field. A cover panel overlies the saddle-holding panel to complete the assembly.

Optical fiber distribution panel assembly

A high density optical connecting block is mounted in a relatively thin, flat panel and is constructed as an array of identical cells that are linked together as a one-piece unit. The cells have a front-to-back depth that is greater than ten millimeters for imparting flexural rigidity to the panel. The array includes at least twelve cells that are arranged in two or more rows and two or more columns. Each cell has a front side that is shaped to receive and interlock with a duplex optical connector and a back side that is shaped to receive and interlock with two simplex optical plugs The duplex connector is a unifying structure that yokes a pair of simplex optical plugs - - into a duplex configuration. The duplex connector includes a pair of side-by-side cavities - each having: (i) an opening at a back end that is shaped to receive a simplex optical plug; (ii) a tubular boss for holding a cylindrical ferrule or a plastic optical fiber, the boss projecting into and out of the cavity from a front-end wall of the cavity and having a central axis that is perpendicular to the front-end wall; and (iii) a retaining feature for holding each simplex plug within the cavity. Additionally, the duplex connector includes latching members - on its top and bottom sides that interlock with the cell.

Duplex optical connector

Apparatus for routing cables in a distribution frame. The apparatus includes a planar panel having takeup spools mounted thereon for the storage of excess lengths of cable. A hollow cylindrical member is mounted for pivoting movement about a pivot axis, where the longitudinal axis of the cylindrical member is parallel to the pivot axis. The cylindrical member has a longitudinally extending gap in its wall. Cables are routed to the panel, are selectively wound on selected ones of the spools to provide slack management, are routed into the cylindrical member, and are routed out of the cylindrical member through the gap.

A U-shaped metal member for securing a circuit component to a circuit board in place of conventional screws and nuts. The element is inserted through aligned holes of the component and the board and is wave soldered to the board for permanent securement.

An assembly for improving the shielding of an electronic system from electromagnetic interference radiation and electrostatic discharge includes a U-shaped conductive bracket as part of the face plate assembly secured to an edge of a circuit card. A conductive latch member is pivotably mounted on the bracket and extends through open slots in the bracket. A conductive gasket is provided on one side of each bracket to engage the opposite side of the bracket of an adjacent face plate assembly. Other conductive gaskets slidingly engage the latch member and seal the slots in the bracket.

EMI/ESD shielding assembly for an electronic system

A tool for extracting a press fit pin from a pin field in a backplane of an electronic system. The tool includes a shaft having first and second ends, with a chuck mounted to the first end and an abutment mounted to the second end. The chuck has a plurality of jaws adapted to grip the pin therebetween and a weight is slidably mounted on the shaft between the chuck and the abutment. After a pin is held by the chuck, the weight is slid along the shaft to contact the abutment and the kinetic energy imparted by the weight to the shaft acts to pull the pin out of the backplane.

A lockable latch and switch actuator assembly for a circuit card includes a spring clip having a slot cooperating with a tab on a latch handle to lock the latch in its closed position. A release portion on the spring clip may be pushed to release the tab from the slot and unlock the latch. The other end of the spring clip is formed with an actuating portion which engages the actuator of a proximity switch mounted to the circuit card when the latch is in its locked position. This actuating portion is spring loaded so that when the latch is released from the locked position, the latch is pushed to an ajar position from which it can be moved to its fully open position.

A conductive tubular member surrounding an optical fiber and its connector termination. When the fiber connector termination engages a complementary connector extending through an opening in a conductive faceplate of an electronics system, the tubular member engages the securement nut holding the connector to the faceplate to function as a waveguide which attenuates radiation leaking from non-conductive gaps in the faceplate and connector. In addition, the tubular member functions as a ground path for electrostatic discharges.

An electronic system having circuit cards insertable into a shelf unit, with shielding between adjacent circuit cards, is provided with a guide fin assembly having protruding guide fins between adjacent circuit card faceplates to limit cumulative tolerance build up between inserted circuit cards.

Circuit card guide assembly

Secondary backplane boards are secured to a main backplane board to provide interconnection paths in a direction transverse to interconnection paths provided on the main backplane board, so that current manufacturing capabilities of multi-layer backplane boards are not exceeded.

High density cross-connection system

An outdoor electronics enclosure which provides both weather protection and heat dissipation. The plastic enclosure is divided into two compartments. The first compartment has apertures in its exterior walls and contains an inner metal heat radiating box containing active electronic components. The second compartment is weathertight and contains passive components.
