Abstract: A one-piece flexible strap clamp which may be wrapped in either of two directions about barriers, or about objects of varying shape such as insulators or lugs, or around fences, or about linear objects such as cable, wire, or bundles of cable or wire. The clamp may be installed onto a variety of support surfaces, such as underground support arms, wildlife/animal barriers, dielectric covers, or tubular guards, without the need for any additional fasteners or other mounting equipment or pieces, and is more tamper proof than previous versions.

Abstract: A new and improved contact terminal for modular, telephone-style plugs. An elongated opening is provided in the central portion of the contact terminal for reducing capacitive coupling between contacts, resulting in better cross-talk isolation. Two parallel signal paths are also provided thereby, reducing signal reflections and improving the VSWR. A substantial savings in gold-plating is also provided by reducing the surface area of the contact terminal.

Abstract: A cable protector for insertion into the open end of a duct or conduit for preventing a cable pulled therethrough from being damaged by the edges of the duct or conduit. The cable protector has a substantially C-shaped cross-section and includes a turned-over lip which encapsulates the end of the duct and prevents the cable protector from being pulled into the duct or conduit. A groove at the juncture of the lip and a curved transitional portion facilitates folding of the cable protector to allow insertion thereof into a variety of sizes of ducts or conduits. Ribs located on the external surface of the body of the cable protector ensures a substantially tubular configuration of the protector after its diameter has been reduced to fit into the intended duct or conduit. The inside surface of the cable protector may be textured to minimize friction.

Abstract: An improved modular plug which permits a normal 6-position plug to accommodate 8 conductors, and a normal 8-position plug to accommodate 10 conductors, without increasing the overall outer width thereby remaining in compliance with FCC regulations. A pair of grooves are formed into the side walls of the cable-receiving cavity to accommodate the extra conductors.

Abstract: An electrical connector incorporates a ground strap conductor that more efficiently grounds the shield of a multi-conductor shielded cable. The ground strap conductor at one end includes a spring contact portion which is indistinguishable structurally and functionally from the spring contact portions of the normal conductors of the connector. The other end of the ground strap conductor is of greatly increased surface area in order to provide a wide, short path to ground for the high frequency EMI and high voltage spikes. A solder post tip is provided for terminating the ground strap after insertion through an aperture in a PCB, and the invention is particularly designed for use with telephone-type modular jacks and modular shielded cables terminated in telephone-type modular plugs.

Abstract: A low profile, wide body modular plug and a multi-conductor shielded cable for termination therein and use with a low profile modular jack adapted to be mounted on a printed circuit board in a closely-spaced array. The low profile design of the plug features latching arms mounted on the outer side walls which mate with cooperating shoulders formed on the inner side walls of the jack. The plug preferably includes a flip-top door formed in the bottom wall thereof for permitting greater accessibility to the internal cable-receiving cavity of the plug. The flip-top door preferably includes a plurality of cable-engaging projections for increasing the pull-out or retention force of the cable and plug assembly. The plug is particularly designed to receive a multi-conductor shielded cable which includes three round shielded wire assemblies arranged in a planar array within an outer encapsulating jacket.

Abstract: A flexible locking clamp (10) particularly designed for use with a tubular guard (50) for a linear body (58) such as a guy wire, cable, conductor, or the like. The locking clamp includes a relatively rigid body portion from which integrally extends a flexible, serrated strap (20). A substantially rigid, arcuate portion (26) connects the strap to the body and is designed to bias the strap at an angle away from the plane of the body. The body also includes means (28) for receiving the free end of the strap after it encircles the desired linear body. The guard wall is provided with aperture means for mounting the clamp, for example, along one edge of a slit that extends longitudinally in the guard. The biased strap provides automatic centering of the linear body in the clamp and guard and permits easy termination of the clamp despite the relative inaccessibility to the interior of the guard.

Abstract: A multi-conductor transmission cable which includes a plurality of parallel conductors each of which may be insulated with a relatively low loss, high velocity of propagation material. The insulations surrounding an adjacent conductor pair may be joined by a homogeneous integrally formed EMF window web formed of the same material as the insulations. The thickness and length of the window webs are selected to control the electromagnetic interference between the conductor pair, as well as the impedance and capacitance. Individual, uninsulated screen conductors may be positioned between adjacent conductor pairs to further minimize EMF interference. The insulated conductors, their EMF window webs, and the uninsulated screen conductors may be encapsulated by either upper and lower layers of laminated insulation or by an extruded outer layer formed of a material having a velocity of propagation different from the conductors' insulations.

Abstract: A connector and terminal for insulated wire which includes a pin section particularly adapted to extend through an aperture in a circuit board. The connector, which is formed of a single piece of electrically conductive metal includes a tubular section adapted to receive and make electrical contact with an insulated wire, and an isolation section which is positioned between the tubular section and the pin section. The isolation section permits the pin section to be wave soldered on the other side of the circuit board without being contaminated by the insulated wire, and also protects the insulated wire from damage during soldering. The isolation section may take one of several forms, and may include a heat sink for further dissipating the heat resulting from the soldering process. Insulation displacement tynes are provided in the tubular section for making positive electrical contact with the wire.

Abstract: A multi-conductor flat transmission cable which includes a plurality of parallel signal conductors each of which is insulated with a low loss, high velocity of propagation material. The insulations surrounding a send and return conductor pair are joined by a homogeneous integrally formed EMF window web formed of the same material as the insulations. The thickness and length of the window webs are selected to control the electromagnetic interference between the conductor pair, as well as the impedance and capacitance. Individual, uninsulated screen conductors may be positioned between adjacent signal conductor pairs to further minimize EMF interference. The insulated signal conductors, their EMF window webs, and the uninsulated screen conductors are encapsulated by an upper and lower outer layer of insulation formed of a material having a velocity of propagation different from the signal conductor's insulations.

Abstract: A plastic guy wire guard which is comprised of a pair of substantially cylindrical tubular portions which are integrally joined to one another by a rapidly tapering neck portion. The design achieves substantial material savings and features a universal single sized guard for installation over any of a plurality of differently sized guy wires and associated anchor assemblies. The plastic guard may be manufactured in a continuous process which features imparting a memory characteristic to the smaller diameter portion of the guard. Upon installation, the larger diameter portion is caused to contract as a means for securing the guard to the anchor. Contraction may be caused by application of heat, either via the sun or a portable source.

Abstract: An insulating protective cover sleeve assembly for a guy wire consisting of a longitudinally slit sleeve of insulating material having an enlarged bottom end portion. In the lower end portion of the sleeve is secured a clamp, likewise of insulating material. The clamp consists of two opposing jaws integrally connected by a flexible band. The jaws are formed with two sets of different-sized opposing arcuate recesses to receive different sizes of guy wires therebetween. One of the jaws has a counterbore hole to receive a clamping screw which is threadedly engageable in the other jaw to tighten the clamp. The wall of the enlarged sleeve portion has a hole registering with the counterbored hole so that a screwdriver or Allen wrench may be drivingly engaged with the clamping screw. A channel-shaped clip engages over the top corner portions of the sleeve segments adjacent the top of the sleeve slit and is secured to one segment.
