摘要： A two-wire line includes a first conductor. A first dielectric thread is wrapped around the first conductor. The two-wire line includes a second conductor. A second dielectric thread is wrapped around the second conductor. The first conductor and the second conductor are at a distance from one another. The distance is smaller than the sum of the thickness of the first thread and the thickness of the second thread.

摘要： A sensor line for detecting an external influence on a cable is described. The sensor line comprises: a first electrically conductive wire, which is enclosed in at least a first sub-region by a first dielectric, and a second electrically conductive wire, which is enclosed in at least a second sub-region by a second dielectric. The sensor line is configured so that a property of the first dielectric is variable under the external influence in at least one region of the sensor line. The external influence is detectable due to a change in a property of the first electrically conductive wire caused by the change in the property of the first dielectric in the at least one region of the sensor line.

摘要： A method monitors a line for changed ambient conditions. The line has a measuring line with a predetermined length and a measuring conductor surrounded by insulation having a known dielectric constant. In the method, an analog signal having a predetermined frequency is generated, the signal is divided into a reference signal and an operating signal, the operating signal is fed into the measuring conductor, a return signal obtained from the operating signal is combined with the reference signal and by a phase shift between the reference signal and the return signal, a measure is determined for the changed condition, particularly for a temperature change.

摘要： A data cable for high-speed data transmissions includes at least one wire pair formed of wires extending in a longitudinal direction and being surrounded by a shielding foil to form a pair shielding. A dielectric intermediate film or foil having a varying lay length is spun around the wire pair between the shielding foil and the wire pair, in order to effectively avoid a damping peak at high transmission frequencies.

摘要： The invention relates to an adapter device (10, 110, 210) for positioning at least one conductor (68), such as a conductor pair, for example, of a cable (70) to be measured, which adapter device comprises a receiving device (12) and a holding clamp (14) which can be attached to the receiving device (12). Attaching the holding clamp (14) to the receiving device (12) fixes the holding clamp (14) in position and alignment relative to the receiving device (12). The holding clamp (14) is designed to receive and clamp the at least one conductor (68) of the cable (70) to be measured in sections in order to fix said cable in the position and alignment thereof relative to the holding clamp (14), such that an end section of the at least one conductor (68) extends beyond the holding clamp (14).

摘要： A method for monitoring a line for a change in ambient conditions. The line includes a measurement line of a predetermined length which has a measuring conductor enclosed in an insulation with a known dielectric coefficient. An analog signal of defined frequency is generated and injected at a feed site. The signal is reflected at a predetermined reflection site and a resulting signal amplitude is measured at a defined measuring point. A measure for the ambient condition, particularly a temperature, is determined from the signal amplitude.

摘要： A device has two machine parts that are movable relative to one another and are connected to each other by a supply line, along which a sensor line is mounted for measuring torsion of the supply line. The sensor line includes two conductors forming a conductor pair, which is stranded during production. The two conductors form a capacitor with a capacitance depending on the spacing between the two conductors. Depending on the direction of torsion of the supply line, the spacing between the two conductors is enlarged or reduced. The sensor line is connected to a measurement unit which is configured in such a way that a capacitance of the sensor line is measured, the torsion being ascertained using the capacitance.

摘要： In a method for monitoring a line, a measuring signal is fed into a measuring conductor at a start time. The measuring signal is reflected at an interference point or at a line end and the reflected portion is monitored to check whether a threshold value is exceeded. If the threshold value is exceeded, a digital stop signal is generated and the transit time between the start time and the stop signal is analyzed.

摘要： A data cable for high-speed data transmission at signal frequencies of >10 GHz includes at least one core pair which is surrounded by a film-shaped pair shield having an inner shielding film and an outer shielding film which, are in electrical contact with one another and in which the inner shielding film is wound around the core pair. By virtue of this measure, an undesired resonance effect is avoided which, in previously wound pair shields, has not allowed use for relatively high signal frequencies. At the same time, an undesired common-mode signal, which would occur in the case of a longitudinally folded shielding film, is thus suppressed.

摘要： In a contact connecting of preferably a number of shielded conductor pairs to a board in particular of a plug for high-speed data connections, the board is formed of multiple layers and contains a conductor path tier and a ground tier. A ground contact zone of the ground tier projects, in a tongue-like manner, towards the connected conductor pairs. In the region of the ground contact zone, the individual conductor pairs are pressed in contact against the corresponding pair shielding thereof. To this end, in particular a clamping element is provided that is also used to achieve the shield contacting.
