摘要:
The invention related to an electromagnetic relay, especially for motor reverse relays applications having a single magnetic system to achieve three switching positions, the magnetic system comprising two armatures, at least one magnet, one core/pole and a mechanical system consisting of two spring arrangements comprising each one central spring and two terminal springs characterized in that the relay has a non-conductive card used to bridge together the two central springs, and having the function to couple the two central spring motion and the two armature motion

The invention relates to a spring member (1) for an electric switching device (84) such as a cradle relay. The spring member (1) comprises a distal end (10) and a proximal end (8) opposite said distal end (10). A base portion (6) comprises said proximal end (10). A contact spring section (2) extends from the base portion (6) to the distal end (10) and is provided with a contacting spot (40). The spring member (1) comprises a return spring section (4) which extends from the base portion (6) alongside the contact spring portion (2). The spring member (1) according to the invention allows for a more compact and simpler design of the electric switching device (84) by replacing for example the armature (96).
摘要:
A relay including a monostable or bistable magnetic system comprises a slider (2) which can be moved parallel or perpendicular to a base plane (1). At least one contact opening element (20) is integrated on the slider (2) for tearing welds of contacts (3, 11). The contact opening element engages behind the moveable spring contact (3) at a variable distance toward the fixed spring contact (11). On opening of the relay, the contact opening element (20) strikes the moveable spring contact (3) with a sudden pull just before the magnetic system is fully opened, so the weld is torn.

With a pole-reversible magnet system with an H-shaped armature (7) for a bi-stable relay, it is proposed that a yoke arm (5) of a first core yoke member (1) is U-shaped and a yoke arm (6) of a second core yoke member (2) is straight, and that the yoke arms (5, 6) lying outside a coil (18) are positioned so that the H-shaped armature (7) is positioned approximately perpendicular to a coil center axis. In this way, it is possible, even with relays having a horizontal slider (19), to realize a low-height relay with a horizontal magnet system.
摘要:
Die Erfindung betrifft ein Relais (1) mit einem Spulenkörper (2), einem den Spulenkörper (2) durchsetzenden Kern (17) und einem Joch (3). Um bei geringer Baugröße eine hohe Schaltkraft zu erzeugen, ist erfindungsgemäß vorgesehen, dass die Querschnittsfläche (Q 1 ) des Kerns (17) im Bereich zum Übergang zum Joch (3) größer ist als im Mittenbereich (31) des Spulenkörpers (2). Durch die Querschnittserweiterung (22, 23) kann ein vermehrter Magnetfluss aus dem Kern geleitet werden, gleichzeitig können im Mittenbereich aufgrund des dort verringerten Querschnitts mehr Spulenwicklungen angeordnet sein. Beide Maßnahmen wirken zusammen und ermöglichen hohe Schaltkräfte bei geringen Baugrößen.
