Abstract:
A method and an apparatus for connecting a coaxial (or a micro coaxial) cable to the bottom side of a printed circuit board (PCB) in order to improve signal integrity of a test circuit. A coaxial or a micro coaxial cable is directly connected to a coaxial cable to the bottom sides of pads located on an exterior later of the PCB.
Abstract:
Managing impedance in coaxial cable termination. In one example embodiment, a method for terminating a coaxial cable is provided. The coaxial cable includes an inner conductor, an insulating layer surrounding the inner conductor, an outer conductor surrounding the insulating layer, and a jacket surrounding the outer conductor. The method includes various acts. First, a section of the insulating layer is cored out. Next, the diameter of the inner conductor that is positioned within the cored-out section is reduced. Then, at least a portion of an internal connector structure is inserted into the cored-out section so as to surround the section of reduced-diameter inner conductor. Finally, an external connector structure is affixed to the internal connector structure. A coaxial cable termination tool for use in the termination of a coaxial cable and a terminated coaxial cable are also disclosed.

Abstract:
Il est proposé un câble (100) comprenant une gaine protectrice (130) dans laquelle est logé au moins un conducteur. La gaine protectrice a une épaisseur minimale et un diamètre extérieur compris dans une plage de valeurs définie par une norme prédéterminée. Le câble comprend en outre au moins une bande indicatrice amovible (150) : qui s'étend longitudinalement sur au moins une portion d'arc de la surface circonférentielle externe de la gaine protectrice; qui est réalisée dans un matériau permettant à la au moins une bande indicatrice amovible d'adhérer à la gaine protectrice, tout en pouvant être détachée de la gaine protectrice sans l'altérer, par application d'une force d'extraction par unité de largeur de la au moins une bande indicatrice amovible supérieure à un seuil prédéterminé; qui a une épaisseur telle que le diamètre extérieur de la gaine protectrice augmenté de l'épaisseur de la au moins une bande indicatrice amovible est compris dans la plage de valeurs.

Abstract:
Apparatuses, systems, and methods are provided for automatically crimping terminals or connectors to wires wherein the terminals or connectors are provided in strip form and may be of varying sizes, shapes, and pitches. An apparatus according to the present invention includes an applicator body and a ram movably mounted in relation to the body and drivable in a first path through a working stroke towards, and a return stroke away from, a crimping anvil. The apparatus further includes a crimping die on the ram for cooperation with the anvil and adapted to crimp a terminal connector located therebetween onto a wire during each working stroke of the ram. The apparatus additionally includes a drive mechanism adapted to contact the strip through pressure engagement and to feed the strip along a second path to locate the leading connector on the strip between the anvil and the die.
Abstract:
A method for connecting first and second elongate conductors using a wedge connector includes: providing a wedge connector including a sleeve member, a wedge member, and a lubricant coating disposed on at least one of the sleeve member and the wedge member, the sleeve member defining a sleeve cavity; mounting the sleeve member on the first and second conductors; and driving the wedge member into the sleeve cavity using a hydraulic power drive tool assembly to secure the wedge connector to each of the first and second conductors.
Abstract:
Verfahren zum Verbinden eines ersten elektrisch leitenden Bauteiles in Form einer mehrere Drähte (11) aufweisenden flexiblen elektrischen Leitung (1) mit einem zweiten elektrisch leitenden, metallischen Bauteil, z.B. einer zweiten elektrischen Leitung (2) oder einem Anschlusselement. Dabei wird auf das freie Ende der flexiblen elektrischen Leitung (1) in eine Hülse (3) eingesetzt und mit dieser verpresst, wird weiters in das freie Ende der Hülse (3) das der flexiblen elektrischen Leitung (1) zugeordnete Ende des zweiten elektrisch leitenden Bauteiles (2) eingesetzt sowie an die flexible elektrische Leitung (I] zur Anlage gebracht und wird durch diese beiden Bauteile (1, 2) elektrischer Strom hindurch geleitet, wodurch deren aneinander liegenden Enden miteinander verschmolzen werden, wobei die Hülse (3) aus einem solchen Metall hergestellt ist, welches gegenüber dem Metall bzw. den Metallen der beiden miteinander zu verbindenden Bauteile (1, 2) einen höheren Schmelzpunkt aufweist.
Abstract:
Cathodes (1) for aluminium electrolysis cells consisting of cathode blocks (4) and current collector bars (2) attached to those blocks whereas the cathode slots (3) receiving the collector bar are lined with expanded graphite lining (9) thus providing longer useful lifetime of such cathodes and increased cell productivity.
Abstract:
An housing for protecting a device from water damage, which is capable of being repeatedly opened and then hermetically sealed even when the device has a wire that must be extended outside of the apparatus. The housing has at least two members that, when juxtaposed and clamped, form a dry interior region. Each member includes a pair of gaskets that together define the dry interior region and substantially form a hermetic seal about a pouch or container. A portal is included through which the wire may extend from a device inside the pouch or container to the outside and a slide mechanism that adjust a gasket around the wire to maintain the dry interior region. The slide mechanism forms a hermetic seal around the wire so that the opening in the pouch from which the wire extends is hermetically sealed. If no wire is present, the slide mechanism may be adjusted to maintain the hermetic seal.
