摘要:
An electromagnetic relay has a core and yoke that are securely attached to the base (10) of the relay with a high degree of precision so that the operating characteristics of the relay do not vary. To this end, two bosses (14) are provided near the lower edge on the inner surface of a hole (12) in a spool (11) of the relay. The bosses (14) are symmetrical with respect to a center line of the spool (11).

A polarized relay comprising a coil block having an elongated coil bobbin a core inserted therein, and excitation coil means wound about said coil bobbin, said core having opposed pole ends projecting upwardly from longitudinal ends of said coil bobbin, said coil block including a permanent magnet interposed between said pole ends; an armature block having an elongated generally flat armature and a set of movable springs carrying movable contacts and held together with said armature by means of an electrically insulating harness molded on said armature, said armature pivotally supported on said coil block to be movable between two contact operation positions and constituting a magnetic circuit with said core and said permanent magnet for polarized operation of said armature; said armature block provided with hinge springs disposed on the lateral sides of said armature, respectively at a longitudinal center thereof for mounting said armature block on said base unit, said hinge spring integrally formed with a beam projecting from said harness and with an anchor tab extending integrally from said beam and secured to a corresponding portion of said base unit, said beam extending from a side post on the lateral side of said armature such that said beam runs over a limited length along the lateral side of said armature, is characterized in that said side post from which said beam extends is offset toward one longitudinal end of said armature from a longitudinal center thereof at which said armature is pivotally supported, one end of said beam being a free end from which said anchor tab extends toward said side posed in opposite relation to said beam.
摘要:
Ein elektromagnetisches Relais weist einen um eine mittlere Achse verschwenkbar gelagerten Anker (10) auf, der in seinen beiden Endstellungen mit seinen beiden Enden an jeweils entgegengesetzten Enden (19, 20) eines Jochs anliegt, so daß sich in jeder Endstellung eine Dreipunktlagerung ergibt. Jedem Ankerende ist mindestens ein Kontaktsystem (21...24) mit einem Festkontakt (28) und einer von dem Anker (10) über einen Betätiger (31, 32) bewegbaren Kontaktfeder (26) zugeordnet. Die Kontaktfedern (26) sind zur Ankerlängsachse (L) seiten-asymmetrisch derart vorgespannt, daß die von ihnen auf den Anker (10) in seinen beiden Endstellungen ausgeübten Stellkräfte (F1, F2) in gleicher Richtung quer zur Ankerlängsachse (L) gerichtet sind. Demgegenüber ist die Ankerlagerung so eingerichtet, daß sie eine zu den Stellkräften (F1, F2) parallele aber entgegengesetze Lagerkraft (K) aufnimmt. Dadurch wird beim Verschwenken des Ankers (10) aus jeder seiner Endstellungen ein gleichzeitiges Ablösen beider Ankerenden von den Jochenden (19, 20) gewährleistet.
摘要:
The present disclosure relates to a device for limiting movement of a movable part in electrical equipment and the electrical equipment comprising the same. The limiting device comprises: a stopper (10) provided in a moving path of the movable part (20) and configured to contact the movable part (20) at a predetermined position to prevent the movable part (20) from moving; wherein the stopper (10) is mainly formed of an elastomer and comprises a stop surface (11), the elastomer being configured to be deformed when the movable part (20) collides with the stop surface (11) in a first direction; and wherein the elastomer further comprises holes (12). With the holes being provided in the elastomer, impact resistance of the elastomer is enhanced, and performance deterioration of the elastomer due to a temperature rise is compensated.
摘要:
A power relay (1) for a vehicle is disclosed, in particular for a utility vehicle. The power relay (1) comprises a housing (2) formed by a connector base (3) and a housing can (4) set thereon, two connection bolts (10) being inserted into the connector base (3) for contacting a load circuit. The power relay (1) further comprises a coil subassembly (20) arranged in the housing and comprising a solenoid coil (30) and an armature (24). The armature (24) is coupled by a force-transmission member (23) to a contact bridge (22) and can shift in the housing, under the effect of a magnetic field generated by the solenoid coil (30), in such a way that the contact bridge (22) can be reversibly moved between a closing position, in which the contact bridge (22) bridges the connection bolts (10) in an electroconducting manner, and an opening position, in which the contact bridge (22) is not in contact with the connection bolts (10). The housing can (4) is designed as an injection-moulded component made of plastics.
