Abstract:
Disclosed is a magnetic latching relay having an asymmetrical solenoid structure, the magnetic latching relay comprising a magnetic circuit portion, a contacting portion, and a drive portion; the magnetic circuit portion comprises a magnetic conductive component, a coil rack, and a coil; the drive portion comprises a movable iron core; further comprising two pieces of magnetic steel, the two magnets being respectively disposed on the two sides of a coil axis and being respectively adjacent to or in contact with the corresponding sides of the magnetic conductive component; and the two pieces of magnetic steel are within the movement range of the movable iron core in the axial direction of the coil, and are biased towards the moving direction of the movable iron core when a contact is in the closed state, such that the retaining force of the moving iron core is substantially the same in both closed and open states of contact. The present invention introduces biased magnetic steel into a relay having a solenoid magnetic circuit structure to make the relay a magnetic latching relay, for ensuring low heat dissipation while solving the problem of unbalanced action reset voltage of a solenoid magnetic circuit, thus improving product performance and operational reliability.
Abstract:
L'invention concerne un dispositif de coupure électrique (1) comportant : - deux bornes fixes (21A, 22A), - un pont mobile (39A) entre une position de fermeture du contact électrique entre les bornes fixes et une position d'ouverture de ce contact électrique, - un système de commande électromagnétique (31A) piloté entre un état ouvert pour placer le pont mobile en position d'ouverture et un état fermé pour le placer en position de fermeture, et - des moyens de manœuvre manuelle (40) qui sont manœuvrables entre une position fonctionnelle dans laquelle le pont mobile est libre de se déplacer entre ses positions d'ouverture et de fermeture, et une position d'ouverture forcée dans laquelle les moyens de manœuvre manuelle maintiennent le pont mobile à distance des deux bornes fixes. Selon l'invention, lesdits moyens de manœuvre manuelle sont également manœuvrables vers une position de fermeture forcée dans laquelle ils bloquent le pont mobile contre les deux bornes fixes.
Abstract:

Abstract:
According to various embodiments of the invention, a relay (100) is suitably formed to exhibit an open state and a closed state. The relay (100) is operated by providing a cantilever (112) sensitive to magnetic fields such that the cantilever exhibits a first state corresponding to the open state of the relay and a second state corresponding to the closed state of the relay. A first magnetic field may be provided to induce a magnetic torque in the cantilever (112), the cantilever may be switched between the first state and the second state with a second magnetic field may be generated by, for example, a conductor formed on a substrate with the relay.
Abstract:
A reed switch (20) employs contact blades (10) which have enhanced flexibility and performance, as a result of the selective removal of material from one or more of the blades (10) without work hardening the remaining blade material. The blades (10) are masked and acid etched in predetermined patterns to provide either a contact region (14), a hinge or fulcrum region (24), or one or more of both. The contact region (14) of the blade (10) optimizes the alignment and magnetic coupling of the switch (20) while minimizing the electrical capacitance in the space between the blades (10) when the switch (20) is open. The hinge or fulcrum region (24) improves blade (10) compliance and flexibility under an applied load. Various geometries of the contact region (14) can be employed to improve the performance and longevity of the switch (20).
