Abstract:
An electrical switching apparatus (2;50;90;100) includes a ferromagnetic frame (8) having first (110) and opposite second (112) portions, a ferromagnetic core (33) disposed therebetween, a permanent magnet (12) disposed on the first portion, a first tapered portion (113) on the opposite second portion; a coil (4) disposed about the core; and a ferromagnetic or magnetic armature (10) including a first portion (114), an opposite second portion (116) and a pivot portion (118) pivotally disposed on the core between the portions of the armature. The armature opposite second portion has a complementary second tapered portion (38) therein. In a first armature position, the armature first portion is magnetically attracted by the permanent magnet and the first and second tapered portions are moved apart with the coil de-energized. In a second armature position, the armature opposite second portion is magnetically attracted by the opposite second portion of the frame and the first tapered portion is moved into the second tapered portion with the coil energized.
Abstract:
A relay (100) includes an L-shaped armature (201) having an upper end bent on both sides to form a stopper (201a). The stopper (201a) is engaged with an edge (204c) of the upper end (204a) of a core (204), and a resilient piece (205c) of a hinge spring (205) supports the armature (201) in such a manner that the armature can oscillate. The periphery of the upper end of the armature (201), when magnetically attracted, comes in intimate contact with the upper end (204a) of the core (201).
Abstract:
The invention relates to an electromagnetic relay comprising a magnetic system consisting of an exciter coil (1), a core (2) and an armature (3) in addition to a socket formed by a through hole plated printed board (4). The side facing the magnetic system of the printed board (4) has strip conductors while the side of the printed board (4) facing the magnetic system forms a basic side of the relay. The printed board (4) also has fixed contact elements (12) which are connected to connecting elements (10, 22).

Abstract:
The invention relates to an electromagnetic relay, comprising a coil (1), a core (2), an armature (4), mobile contacts (5) which are located on the armature, a frame element (10) and fixed contacts (12) which are located on the frame element (10). The fixed contacts (12) are arranged on contact springs (9) which are fixed on the frame element (10) at their fixed ends and each have a free end. The invention also relates to a method for producing the inventive relay.
Abstract:
Various high voltage systems may benefit from a suitable relay system. For example, a relay box may be provided with a shock and vibration resistant arrangement including a sealed coil box within the sealed relay box. For example, an apparatus can include a coil box containing coils, inside pole pieces, and permanent magnets, wherein the coils, inside pole pieces, and permanent magnets can be configured to actuate an armature assembly external to the coil box. The apparatus can also include outside pole pieces configured to move a relay armature of the armature assembly responsive to energizing of the coils. Moving the relay armature can include overcoming a latching of at least one of the permanent magnets.
Abstract:
A contact arrangement for a relay 1 enables a particularly high maximal current and at the same time safe operation, if it has a base 10 to which a static contact 20 is mounted and if it further comprises a movable contact 30, which is movable between a first position and a second position wherein the movable contact electrically connects the static contact 20 in its first position and wherein the movable contact is disconnected from the static contact in its second position and a stranded wire 35 connecting the second contact with a connection terminal 42 and which mechanically supports the movable contact 30.
Abstract:
Déclencheur électromagnétique, du type relais différentiel, comprenant: une armature (1) en forme de U, dont les extrémités des deux jambages (4, 5) constituent deux surfaces polaires coplanaires; une palette (2) pivotante entre deux positions respectivement à distance, cʼest à dire laissant subsister un entrefer avec lʼarmature (1) et, en position armée du déclencheur, au contact desdites surfaces polaires, fermant ainsi le circuit magnétique constitué par ladite armature (1) et ladite palette (2), le point de rotation (3) de la palette (2) se situant au voisinage immédiat de lʼextrémité de lʼun des jambages (4) de lʼarmature (1); un aimant permanent (6) de polarisation du circuit magnétique, disposé entre les jambages (4, 5) de lʼarmature (1) et créant une force magnétique permanente dʼattraction de la palette (2) vers les surfaces polaires, force magnétique qui sʼexerce à lʼencontre dʼune force de rappel dʼun ressort (13); une bobine dʼinduction (16) entourant le circuit magnétique, reliée par exemple à un circuit à contrôler, en vue de modifier lʼéquilibre initial entre la force magnétique et la force de rappel du ressort (13). Lʼaimant (6) est positionné au voisinage du jambage (5) de lʼarmature (1) opposée au jambage (4) proximal du point de pivotement (3) de la palette (2).
