Abstract:
An arrangement for supporting an optical fiber and related optical components in a raised position above a surface of a printed circuit board on which electrical components are mounted includes a support which defines an endless, oval raceway for receiving one or more optical fibers, legs mounted on the support and secured to the printed circuit board for supporting the raceway defining support above the surface of the printed circuit board a predetermined distance so that the support does not interfere with the electrical components mounted on the printed circuit board, and one or more ramps joined to the raceway and extending from the raceway substantially to the surface of the printed circuit board. The ramps provide support for the optical fibers over portions of the fibers where they are coupled to an opto-electronic transmitter or receiver mounted on the printed circuit board.
Abstract:
A connector block (20) which contains a plurality of electrical contacts (38) is mounted on mounting tabs (32) of a mounting bracket (22) and is releasably locked in place by means of projections (56) on release tabs (52) at the ends of the block. The release tabs are resiliently bendable away from the end wall to pull the projection (56) out from locking holes (34) in the mounting tabs (32).
Abstract:
An electrical connector for connecting together cables containing at least two twisted wire pairs which transmit and receive different electrical signals, The connector has an electrically conductive shield between pairs of connector elements which are respectively connected to the different twisted wire pairs. The connector also has an insulative block with printed circuit segments and switch contacts which together form shunts to connect the twisted pairs together when the connector is disconnected.
Abstract:
A specialized package for shipping and using fiber optic cable which simplifies handling prior to installation, and serves as a storage device after the cable has been installed. The disclosed device comprises a fiber board box of planar configuration with an integral lid secured in closed position by tuck tabs. Positioned within the box are a pair of planar foam layers each defining a congruent circular opening. Positioned within the opening is a flat spool having a core and at least one detachable end cap upon which the fiber optic cable is coiled, and from which project a pair of connectorized ends. When the package is closed, the connectorized ends are gently clamped between the foam layers, thus protecting the same against damage during shipment.
Abstract:
An elongated electrically insulative connector block (12) contains internal spring finger electrical conductors 78 arranged in sets in adjacent cells (C.sub.1, C.sub.2, ... C.sub.n) which are arranged in a line, with adjacent cells being mutually offset in a direction transverse to the line; and a connector with a plurality of insert elements lying in parallel planes which are mutually offset so that each element can be inserted into adjacent cells.
Abstract:
A series of individual telephone subscriber circuit modules for use with telephone connector blocks having flat insulation displacement clips projecting from a planar surface thereof. The block mounts a grounding strip medially positioned on said surface. The modules employ known protection components, and in various modifications, are suitable for providing alternatively three point protection or five point protection utilizing either or both of gas tube and fuse components. Depending upon specific requirements, each module protects either two or four subscriber circuits.
Abstract:
A telephone jack panel assembly suitable for modular digital installations which facilitates connection at a period of time when the frame upon which it is installed is already congested by previously installed connectors. As contrasted with conventional construction, the disclosed panel is provided with a rearwardly extending housing, which mounts plural multi-contact connectors which are interconnected to corresponding multi-contact jacks mounted upon the free ends of incoming telephone cables. Thus, only a relatively few plug connections need be made without the necessity of removing the jack from the main frame. The housings for each jack panel are so contoured as to form a horizontally oriented recess, one for each jack panel, when a plurality of such jack panels are assembled on the main frame in stacked relation.
