Abstract: A patch panel for optical fibers includes a tray for supporting coiled portions of the fibers, a plurality of transversely spaced apart tabs, spaced backwardly from the front end of the tray and extending perpendicularly upwardly from the tray and a plurality of modular connector assemblies each slidably mounted on said tray between respective pairs of adjacent tabs. The modular connector assemblies each include a modular connector yoke for mounting optical fiber connectors on the tray. The tray includes tracks for slidably mounting the tray in a rack.

Abstract: An electrical connector of the split cylinder type for terminating or connecting an electrical wire comprising an elongated tubular sleeve section, an elongated wire receiving slot, a flared entryway leading into the wire receiving slot and a wire retaining means for temporarily retaining the electrical wire within the flared entryway in position for termination or connection within the wire receiving slot.

Abstract: A connector panel for terminating and/or cross-connecting telecommunications or data transmission circuits including a base having a first set of connector receiving openings, a plurality of connectors adapted for connection with the base, a connector retaining member having a second set of connector receiving openings, and elements for securing the connector retaining member and the base together.

Abstract: An electrical connector module adapted for use in an access member to provide access to a circuit. The module includes an insulated housing surrounding a connector element and the housing includes a pair of side walls with edges forming a wire gripping slot. The module has particular advantages when arranged in an array to provide access to a plurality of circuits. The invention also relates to an improved connector element usable in connection with the electrical connector module.

Abstract: An electrical connector primarily designed for use in telecommunications and other applications where quick and reliable wire connections in great magnitude are required is disclosed. The connector has a elongated cylindrical shape with an insulation displacement slot running parallel to its longitudinal axis. It is surrounded by and mounted in a sheltering insulating housing. Adjacent the insulation displacement slot on opposite sides of the conductor are V-shaped or other shaped slots which in combination with the insulation displacement slot, form cantilever beams which act independently of the flexing of the cylinder itself. This creates a modified spring rate in the area where connecting wires are held after they are inserted longitudinally into the insulation displacement slot and moved to a final connection position.

Abstract: An electrical connector of the split cylinder type for terminating or connecting an electrical wire comprising an elongated tubular sleeve section, an elongated wire receiving slot, a flared entryway leading into the wire receiving slot and a wire retaining means comprising a wire retention groove with a neck portion of reduced width for temporarily retaining the electrical wire within the flared entryway in position for termination or connection within the wire receiving slot.

Abstract: A barrier block is disclosed which incorporates an electrical terminal in the form of a hollow cylindrical barrel provided with a longitudinal slot divided into one or more pairs of wire gripping jaws. The barrel is integral with a second electrical contact seatec on a web which interconnects a pair of partition walls. Opposite ends of the barrier block are molded with intermateable channels allowing a plurality of barrier blocks to be intermated and latched together.

Abstract: A barrier block is disclosed which incorporates an electrical terminal in the form of a hollow cylindrical barrel provided with a longitudinal slot divided into one or more pairs of wire gripping jaws. The barrel is integral with a second electrical contact connected to the barrel by an integral loop serving as a sloped wire stop at the entry of said barrel. Each electrical terminal is mounted on a web which interconnects partition walls. One of the partition walls is provided with a hook and a latch. Another partition wall is provided with a hook receiving recess and a latch receiving recess allowing a plurality of barrier blocks to be hooked and latched together.

Abstract: A fuse holder includes a pair of electrical terminals which releasably clamp opposite ends of a fuse. Each terminal has a wire terminating, slitted barrel portion to which wires are connected without a need for tools. The fuse and the terminals are enclosed within a two piece dielectric housing adjustable in length to accept a range of fuse lengths. Means are provided to prevent undesired loosening or opening of the housing.

Abstract: The disclosure relates to an insulation cover for a slotted barrel electrical terminal of the type mounted to a printed circuit board. The cover is molded of dielectric material in cylindrical form with an open end for receipt over a barrel terminal, and a closed end which is slotted to provide a seat against which an insertion tool is registered. A lengthwise slot of the cover receives one or more wires therein and grips across the cross section of each received wire to provide a strain relief. A projecting tab on the cover is utilized for gripping when removal of the cover from the terminal is required.

Abstract: The disclosure relates to a metal plate terminal rolled into a barrel configuration having a longitudinal open seam defining a wire receiving slot. The terminal defines wire gripping jaws on either side of the seam. A transverse slot intersects the open seam dividing the jaws into two tandem pairs. An enlarged flared entryway is provided in the second pair of jaws for the open seam. The first set of jaws have tab portions projecting toward the second pair of jaws for guiding a wire along the open seam from the first set of jaws to the second. The transverse slot is of substantial width to prevent abrasion of the jaws with one another. The transverse slot further is of arcuate configuration, perpendicularly intersecting the open seam and incising one-fourth of a circumference of said barrel configuration on either side of said open seam.
