Abstract:
The invention relates to an improved design for micro relays comprising a membrane 1 with slits 2 defining suspension beams 3 and actuation portions 4. Large areas of actuation portions 4 can be combined with small elastic constants of suspension beams 3 in order to improve the contact forces.
Abstract:
Die mikro-elektromechanische (MEMS-) Kontaktanordnung beinhaltet mindestens ein erstes Kontaktstück (1) und ein zweites Kontaktstück (2), wobei mindestens eines der beiden Kontaktstücke (1;2) antreibbar ist. Die MEMS-Kontaktanordnung ist mittels des antreibbaren Kontaktstücks (1;2) zwischen einem ersten Schaltzustand (A) und mindestens einem zweiten Schaltzustand (B) schaltbar, wobei die beiden Kontaktstücke (1,2) in dem ersten Schaltzustand (A) voneinander getrennt sind und in dem zweiten Schaltzustand (B) einander kontaktierend sind. Es ist dadurch gekennzeichnet, dass mindestens das erste Kontaktstück (1) mindestens ein flexibles Kontaktsegment (11) und einen Kontaktsegment-Träger (12) aufweist, sowie dadurch, dass das mindestens eine flexible Kontaktsegment (11) mittels mindestens des zweiten Kontaktstücks (2) bei dem Schaltvorgang elastisch verformbar ist. Die elastische Verformbarkeit des flexiblen Kontaktsegments (11) ergibt sich aufgrund der Dünnwandigkeit des flexiblen Kontaktsegments (11). Es kann eine sichere und gute Kontaktierung erreicht werden. Grosse Kontaktflächen (5), eine vorgebbare Mehrzahl von Kontaktpunkten (5) und selbstreinigende Kontakte durch Reibung zwischen den Kontaktstücken (1,2) sind realisierbar.
Abstract:
The cable connector (19) for making an electrical contact with a cable conductor (2) of a cable (1) comprises two legs (190), at least one of which can make electrical contact with a cable conductor (2) inserted into the cable connector (19) into a contacting position, and the two legs (190) are capable of exerting a contacting force on a cable conductor (2) in the contacting position for holding the cable conductor (2) in the contacting position. When there is no cable (1) inserted in the cable connector (19), the legs (190) exert an non-vanishing initial force on each other. In other words, the cable connector has two prestressed legs. Ends of the legs press against each other with some force prior to the insertion of any cable into the connector. The cable connector can, e.g., be used as an insulation displacement connector and in connector terminal blocks. Methods for manufacturing such a cable connector (19) comprise methods, in which an elastic deformation in at least one section of the cable connector (19) is performed, while another section of the cable connector (19) is plastically deformed. Preferably, the cable connector is integrally made from one piece of bent sheet metal.
Abstract:
The cable connector for making an electrical contact with a cable (1) having a cable conductor (2), comprises a guiding means (4) for receiving one end (1a) of the cable (1) in an initial state (O), a contact element (6) for electrically contacting the cable conductor (2) in a final state, and a holding means (18) for holding the cable (1) in electrical contact with the contact element (6) in the final state, wherein the guiding means (4) and the contact element (6) are moveable relative to each other, allowing for movements between the initial state (O) and the final state. A spring device (7) is provided, which is arranged such that it exerts a force against the movement from the initial state (O) to the final state, and which moves the cable (1) towards the initial state (O) if the cable is not in the final state. A contact ensuring mechanism (8) can be provided, which in the final state reduces the force exerted by the spring device (7) against the movement from the initial state (O) to the final state. The cable connector can, e.g., be used as an insulation displacement connector and in connector terminal blocks.
