Abstract:
A connector plug for interconnecting plurality of twisted pairs of wires in a cable has a body portion having a flared recess therein. A flared insert fits within the recess and has a top surface having first and second wire pair guiding channels and a bottom surface having third and fourth wire pair guiding channels extending from a cable entrance end to a contact end of the body portion. The insert has a channel defining cross-tail which is insertable into the end of the cable and the cable is crimped thereto by a crimping ring. A contact bearing contact base is mounted on the contact end of the body portion with the contacts immediately adjacent the end of the insert. Thus, the wires stay twisted from the cable to the contacts.
Abstract:
A communication plug for terminating a cable carrying a plurality of conductors. The communication plug includes a strain relief housing for receiving the cable and a jack interface housing for communication with a jack. Confined within the two housing components are a plurality of conductive members carried by a blade carrier. In a preferred embodiment, the jack interface housing segregates the conductive members in a substantially circular array largely conforming to the arrangement of the conductors in a round cable.
Abstract:
A tunable blade structure for use in a communication plug terminating a cable carrying a plurality of conductors. One end of the blades is designed as an insulation displacement connector (IDC) for electrical communication with the conductors from the cable. The other end of the blades is designed as a jack contact region for electrical communication with jack springs. Between these two ends are three regions for manipulating the electrical characteristics of the blades: a capacitive coupling region, an inductive coupling region and an isolation region. By appropriately designing these three regions, electrical interference (i.e., crosstalk) between the conductors can be optimized.
Abstract:
A substantially warp-free laminate polymeric film structure is obtained by a fabrication process in which the individual layers of polymeric film that are to be laminated together to form a card or similar structure are selected such that the mechanical properties of one layer or pair of layers are offset by those of another layer or layer pair wherein each polymeric film layer is bonded to its adjacent polymeric film layers by adhesive layers wherein the adhesive layers have a tack point temperature that is within 10.degree. C. of the glass transition temperature of said polymeric film layers. The properties of the layers which may be subject to this consideration include, for example, the layer thickness, tensile strength, elongation factor, shrinkage rate, and machine processing direction. In an illustrative three-layer substrate embodiment of the present invention, the tensile strength, elongation factor, and shrinkage rate of the outer film layers of the substrate are the same, with the outer layers having a higher tensile strength value than the inner layer tensile strength. The orientation of the film's processing and machine direction and the orientation of the coil set of the film are also considered in arriving at a matched layer set.
Abstract:
An adjustable dressing mirror assembly includes a support, a mirror-mounting unit, and a positioning device. The positioning device includes a guiding seat connected pivotally to the support, a driving plate connected pivotally to the mirror-mounting unit, a sliding block, a movable member, a positioning rod, and a resilient member. The guiding seat includes an accommodating chamber and a plurality of positioning grooves. The driving plate and the sliding block are movable in the accommodating chamber. The positioning rod is disposed fixedly on the movable member. Engagement between the positioning rod and the positioning grooves is allowed with assistance of the resilient member during movement of the driving plate within the accommodating chamber from a rear limit position to a front limit position, and is prevented during movement of the driving plate within the accommodating chamber from the front limit position to the rear limit position.
