Abstract:
A contact arrangement (7) for electrically contacting an inner and an outer bearing element (5a, 5b) of a rotational bearing (3) allowing a coaxial rotation between the inner and outer bearing elements (5a,5b) is provided. The contact arrangement (7) comprises - a contact holder (9) mountable on a first one of the two bearing elements (5a), - at least two sliding contact elements (11a,11b) mounted on the contact holder (9), wherein each sliding contact element (11a,11b) is suitable for forming a sliding contact with a part of a surface (13a,13b) of the second one of the two bearing elements (5b), wherein the contact holder (9) and the sliding contact elements (11a, 11b) are disposed such that a secondary winding (15) is formed with at least one winding loop (15) extending along a first sliding contact element (11a), the contact holder (9), the second contact element (11b) and a part of the surface (13c) of the second bearing element (5b), provided that the surface is formed of an electrically conductive material. The contact arrangement (7) further comprises a primary winding (17) with at least one winding loop (17i), wherein the primary (17) and secondary (15) windings are disposed to form a transformer. Furthermore, a rotational bearing with at least one such contact arrangement is provided, as well as a wind turbine with such a bearing and a method for operating such a rotational bearing.
Abstract:
A terminal connection structure adaptable to various connection methods is provided. The terminal connection structure includes: a pair of tab terminals 62 and 63 that are provided on a base 20 housed in a housing; and a pair of terminal portions 62c and 63c that are provided in the tab terminals 62 and 63 in parallel and that are each exposed from the housing so as to be capable of being connected to an external terminal. A terminal unit 60 disposed so as to sandwich a terminal plate 61 with the pair of tab terminals 62 and 63 is capable of replacing the base 20.
Abstract:
The invention relates to an electrical motor connection (1), in particular of an electrical cooling fan motor (2) for a motor vehicle, having a connected cable harness (5) whose cable ends are connected to a motor-end connecting terminal (9). A connecting housing (8) has two housing parts (8a, 8b), which are joined together in the assembled state to form a cavity (19), and which hold connection-end cable ends of the cable harness (5), with one of the housing parts (8a) having at least one filling opening (26, 27), which opens into the cavity (19), for filling with a curable encapsulation compound, and with the cured encapsulation compound surrounding the cable ends in the area of the connecting terminal (9), and being joined to the housing parts (8a, 8b).
Abstract:
The invention relates to a contact means (100) for attaching an end of a cable (110). The contact means (100) has a casing (300) with an inner chamber (320) for receiving a section of the cable (110) in the region of the cable end, and a pull relief element (200, 201, 202, 203) which can be fastened to the casing (300) in the inner chamber (320), with a pull relief section (220, 221, 222, 223) and at least one contacting section (240, 241). The pull relief section (220, 221, 222, 223) is formed to fix a cable sheath (120) of the cable (110). The contacting section (240, 241) is formed to contact a shield (130) of the cable (110).
Abstract:
This invention relates to a screen device comprising an upwardly and downwardly rollable screen, a motor (1) to drive the upward and downward rolling movement and a compactly installable electrical connection with a male (2) and a female connecting piece (6) for the electrical connection of a power supply cable (5) to the motor (1), wherein the contact pins (4) of the male connecting piece (2) extend substantially at right angles to the electrical wires (3) to which they are connected and/or wherein the contact sockets (8) of the female connecting piece (6) extend substantially at right angles to the electrical wires (7) to which they are connected.
Abstract:
Die Erfindung betrifft eine Anschlusssteckkupplung zur Spannungsversorgung eines Mehrphasenmotors, mit einem Steckkupplungsgehäuse, das eine der Anzahl der anschließenden elektrischen Anschlussleitung entsprechende Anzahl von elektrisch leitfähigen Durchgangselementen aufweist. Mittels der Durchgangselemente ist eine elektrische Verbindung der Anschlussleitungen zu mit den Wicklungsleitern des Motors verbundenen Steckkontakten eines außen an einem Motorgehäuse des Mehrphasenmotors angebrachten Anschlusssteckers herstellbar. Die Betriebsart des Motors in Dreiecks- oder Sternschaltung ist durch interne Brückenkonfiguration der Durchgangselemente festlegbar. Dazu weist das Steckkupplungsgehäuse einen von einem Anschlussbereich für die Anschlussleitungen getrennten Codierbereich auf, der vorzugsweise als abgeschlossener Codierraum ausgebildet ist, so dass der Anschlussbereich einen von dem Codierraum abgetrennten Anschlussraum bildet. Die Brückenkonfiguration ist als interne Steckverbindung ausgebildet und wird mittels einem Codierstecker vorgenommen.
