Le verrou 44 est équipé d'une paire d'étriers 48, 50 ferromagnétiques, et d'une lame ressort 52 de rappel vers une position inactive. A limiting circuit breaker comprises a system of electrodynamic repulsion contacts 26, 14, and an electromagnetic lock 44 arranged in the vicinity of the contact system, and electrically isolated from the latter. The actuation of the latch 44 towards the active position results from the action of the electromagnetic field due to the passage of a short-circuit current in the pole, so as to temporarily keep the movable contact 14 open after repulsion. The lock 44 is equipped with a pair of ferromagnetic calipers 48, 50, and a leaf spring 52 for returning to an inactive position.

Anti-rebound latch for current limiting switches

D-4019(CID) ANTI-REBOUND LATCH FOR CURRENT LIMITING SWITCHES ABSTRACT OF THE DISCLOSURE a multipole circuit breaker is constructed with a single rod pivotally mounting all of the movable contact arms to a common one piece molded insulating carrier. Individual torsion springs engage each of the contact arms to provide contact pressure when the circuit breaker is closed. The construction of the contact arms and carrier are such that under severe overcurrent conditions electro-dynamic blowoff forces acting on the contact arms may bring about contact separation that is substantially as great as the contact separation that takes place when the circuit breaker is opened normally by its contact operating mechanism. An individual anti-rebound pin for each pole engages the contact arm of the associated pole to prevent rebound reclosing after electrodynamic opening. A camming means on the carrier releases the anti-rebound latches to permit manual closing of the contacts.

ELECTRICAL SWITCHING APPARATUS FOR ELECTRICAL INSTALLATION

Current limiter switch assembly - is actuated by electro-dynamic force and has rigid bridge with contacts on either side

A current limiter switch is used. It is designed for actuation by electrodynamic forces. A rigid bridge (11) bears contacts (9) and (10) at either end which abut contacts (7) and (8) when the switch is conducting. The bridge also carries a central locking piece (25) which is secured by pivoted bales (20) (21) under spring bias (22). Primary pivoted bales (5) and (6) carry contacts (7) and (8), and move under electrodynamic force to abut the bales (20, 21) so releasing the lock and opening the switch.

Electromagnetic switch with- two symmetrically pivoted arms - has arms integral with armature with spring transverse to movement of support

An electromagnetically driven switch comprises two symmetrically pivoted arms (19, 22) carried by a support (6, 50) integral with the armature and fixed to them by a spring. The spring is transverse to the movement of the support. Each arm has a movable contact at its end. The auxiliary electromagnetic appts. consists of a U-shaped magnetic circuit (33) which cooperate with a movable blade transverse to the support and having two bearings. The bearings act on the arms in a region contained between their pivotable axis (20) and a piston near the movable contact where they exert repulsive electrodynamic forces. These forces are created by the conductor to the fixed contact. The action on the arms moves the mechanism in a second stable tripping position corresp. to a third position of the contacts.

An electrical switch and a switching blade therefor

Energy regulators which use a bi-metallic strip to open and close electrical contacts are commonly used in household appliances for temperature regulation. This approach however often results in a slow connection and disconnection of the electrical contacts. This can result in arcing which can reduce the life of the switching components and/or cause the contacts to bond together which poses a potential safety risk. Disclosed is a switching blade suitable for use in an energy regulator in which the electrical contacts are connected and disconnected rapidly. Also described is an improvement to the construction of the switching blade whereby the movement of the blade may provide an impact or jolt to separate contacts which may have bonded together.

Device for electric contact with improved opening

FIELD: electrical engineering. SUBSTANCE: device of electric contact comprises fixed contact (1), contact (2), moving between position of contact connection and opening position, and two current paths (31, 32), rigid and movable relative to each other. Movable contact is installed together with one of current paths (31) with possibility of rotation around axis of rotation (X) so that in position of contact connection of movable contact electric current flowing along current flow paths, creates between said paths an electromagnetic force, which is converted into bearing force for said movable contact on fixed contact. According to invention axis of rotation (X) is installed on holder (41), movable relative to fixed contact (1), and movable contact (2) moves between its opening position and its position of contact connection by moving holder (41) relative to fixed contact (1). Distance between current paths (31, 32) remains constant during movement of movable contact element (2) relative to fixed contact element (1). EFFECT: technical result is improved insulation properties of device in opening position of movable contact element. 7 cl, 10 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (51) МПК H01H 1/56 (13) 2 598 539 C2 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2012114088/07, 10.04.2012 (24) Дата начала отсчета срока действия патента: 10.04.2012 (72) Автор(ы): КОТТОН Ги (FR) (73) Патентообладатель(и): ЛЕГРАН ФРАНС (FR), ЛЕГРАН СНС (FR) Приоритет(ы): (30) Конвенционный приоритет: (43) Дата публикации заявки: 20.10.2013 Бюл. № 29 R U 27.04.2011 FR 1153598 (45) Опубликовано: 27.09.2016 Бюл. № 27 2 5 9 8 5 3 9 R U (54) УСТРОЙСТВО ЭЛЕКТРИЧЕСКОГО КОНТАКТА С УСОВЕРШЕНСТВОВАННЫМ РАЗМЫКАНИЕМ (57) Реферат: Устройство электрического контакта ось вращения (Х) установлена на держателе (41), содержит неподвижный контакт (1), контакт (2), подвижном относительно неподвижного контакта перемещающийся между положением ( ...

Contact strip with spring loaded section for relay - has section of reduced thickness actuated by armature via link

A contact spring for a relay with a spring loaded section and a leg of increased thickness. The leg is inserted in a cutout in a base plate where it is held rigidly. The spring loaded section (26) is an integral part of the leg (25). The thickness of the contact spring (8, 9) is reduced in the spring loaded area compared to the leg. The transitional zone between the leg and the spring loaded area varies in all directions. The spring is stamped out of a sheet where the thickness is reduced over part of the surface. The contact springs are actuated by the armature (4) via a link (5) held in a neutral position by a spring when the magnet is not excited.

Contact arrangement for current limiting circuit breaker

Die Erfindung betrifft eine Kontaktanordnung für strombegrenzende Schutzschalter im Niederspannungsbereich mit festgehaltener elektrodynamischer Kontaktöffnung. Sich um einen Lagerbolzen (14) windende Kontaktdruck-Drehfedern (30; 32) stützen sich jeweils zwischen einem federkraftbeaufschlagten Rastnocken (44; 46) und einem Arm einer Drehkontaktbrücke (16) ab. Durch entsprechende kopfseitige Formgebung des Rastnockens (44; 46) wird beim Auftreten eines Kurzschlussstromes der auf die Drehkontaktbrücke (16) wirkenden elektrodynamischen Öffnungskraft ein veränderliches Drehmoment entgegengesetzt. Dieses durch die Kombination aus Drehfedern (30; 32) und federbeaufschlagten Rastnocken (44; 46) erzeugte Drehmoment bewirkt zum einen eine anfängliche Verzögerung der Abstoßbewegung und zum anderen den Übergang der Drehkontaktbrücke (16) in eine rastende Abstoßstellung. The invention relates to a contact arrangement for current-limiting circuit breaker in the low voltage range with retained electrodynamic contact opening. Contact pressure torsion springs (30, 32) that rotate around a bearing pin (14) are each supported between a spring-loaded locking cam (44, 46) and an arm of a rotary contact bridge (16). By appropriate head-side shaping of the latching cam (44, 46), a variable torque is opposed when a short-circuit current occurs on the rotary contact bridge (16) acting electrodynamic opening force. This torque generated by the combination of torsion springs (30; 32) and spring-loaded detent cams (44; 46), on the one hand, causes an initial deceleration movement and, on the other hand, the transition of the rotary contact bridge (16) to a detent detent position.
