摘要:
Electric power transmission device (200) for a rotatable friction clutch arrangement, more particularly for a motor vehicle driven by an internal combustion engine, the friction clutch arrangement having an actuating device with at least one electrical actuator rotatable with the friction clutch arrangement, the power transmission device having an inductive rotary transmitter (202, 204) with a stator (202) associated with an electric power source and a rotor (204) associated with the at least one actuator, for non-contact transmission of electrical energy between the stator and the rotor, and the power transmission device having an electrical contact for contact-based transmission of electrical energy from the power source to the at least one actuator, in order to increase reliability and keep construction cost low.
摘要:
The present invention is a full-rotational freedom conductor assembly for conducting electricity between a pair of coaxial electrically conductive members (4,80. The conductive members are provided with complementary, planar tracks (3, 7) and are relatively rotatable about a common axis (38) thereof. The invention includes a pair or pairs of opposing coupler halves (1, 2) having a planetary axis, with track-adapted profiles. The pairs of coupler halves are rotatably confined between the tracks enabling electrical contact between the tracks of the conductive members. The invention further includes a force source (13, 14) located at least partially between the coupler halves. The force source applies force to each of the coupling halves in a direction substantially parallel to the second common axis. The force is applied to the pairs of coupler halves in a manner that enables the coupler halves to be flexibly retained between the tracks.
摘要:
Beschrieben werden mehrere Ausführungen einer Rollband-Kontakt-Einheit zur permanenten oder bewegungsabhängig intermittierenden elektromechanisch galvanischen Verbindung zweier Systeme. Die Verbindung erfolgt über abrollende, ein- oder mehrlagige, elektrisch leitende und im entspannten Zustand kreisförmige Schleifen bildende Blattfedern, die über zwei örtlich unterschiedlichen Lagerstellen an eine passende Kontaktfläche angedrückt wird. Die Geometrie der Feder im entspannten Zustand weicht (wie bei Federn üblich) von der Geometrie im angedrückten Zustand ab und übt dadurch eine Kontaktkraft auch oder nur außerhalb der Lagerstellen auf die Kontaktfläche aus, was den effektiven Stromflussquerschnitt im Kontaktbereich günstig beeinflusst. Der Andruck der Blattfedern (Rollbänder) an die starren Kontaktflächen erfolgt mit Andruckrollen als Andrucklager. Die Ausführung 3 aus der Beschreibung zur Patentanmeldung präzisiert das Prinzip, und zeigt die galvanische Verbindung von Kontaktbahnen auf dem Außenmantel von Hohlzylinder (27) mit radial gegenüberliegenden Kontaktbahnen in dem Hohlzylinder (30). Die Hohlzylinder (27) und (30) rotieren relativ gegeneinander, die Kontaktbänder (Blattfedern) (33) werden durch die Andruckrollen (34) an den inneren Zylinder gedrückt, und durch die Andruckrollen (35) an den äußeren. Die Blattfedern (33) sind so dimensioniert, dass deren Andruckkraft an die starren Kontaktbahnen ausreicht, um ein schlupffreies Abrollen auf den Kontaktbahnen zu erzielen. Die Andruckrollen (34, 35) sowie die Zentrierrollen (37) sind in einem Rollenträger (siehe Beschreibung) gelagert, der eine von den Rotationsgeschwindigkeiten der Hohlzylinder (27, 30) abhängige Rotation vollführt und dabei die Rollen (34, 35, 37) samt den Kontaktbändern (33) mitnimmt. Die Ausführung 1 aus der Beschreibung zeigt den Einsatz als Rollbandkommutator. Ein Außenläufer-Gleichstrommotor mit Permanentmagneten am Außenläufer und einem ortsfesten Anker weist 4 parallele Leiterbahnen (5, 6, 7, 8) auf, die mit den flexiblen Kontaktbändern (4) paarweise galvanisch verbunden sind. Die Bahn (6) ist mit der ortsfesten +Versorgung verbunden, (8) mit der-Versorgung. Die zu (6) und (8) benachbarten Bahnen (5) und (7) sind 3-geteilt, stellen also die Kommutatorlamellen dar. Die Lamellen sind in geeigneter Weise mit den Ankerwicklungen verbunden. Der Außenläufer (10) trägt die Rollenandruckeinheit (9) und bewirkt das Abrollen der Kontaktbänder (4) auf den Kommutatorlamellen, die während einer Umdrehung des Läufers nacheinander mit den Versorgungsspannungen galvanisch verbunden werden.

摘要:
A rolling contactor is described for testing electronic devices having a plurality of very closely spaced, linearly aligned terminals, e.g. ceramic chips (6) containing an array of capacitors, packaged no larger than a single 1206 chip capacitor (0.120 x 0.60). Such chips have like pluralities of linearly aligned terminals (10, 12) along opposite sides. The contactor (2) includes a plurality of juxtaposed contact wheels (20, 24), each wheel being individually suspended by a corresponding cantilever arm (52, 54). The wheels are spaced to register with a line of terminals, and the arms are resilient enough to apply, when flexed, sufficient axial force to their respective wheels to make good contact with the terminals. Two of such multiple rolling contactors can be opposally positioned for simultaneously contacting lines of terminals on opposite sides of a chip array passing therebetween. In such a case, the wheels of one contactor are positioned to impinge registered terminals along one edge of the array, while the wheels of the opposing contactor simultaneously impinge registered terminals along the opposite edge of the array.
