摘要:
Das erfindungsgemässe elektrischen Installationsgeräts (1) wird aus einem erstes Teilerzeugnis (10) und aus ein zweites Teilerzeugnis (12) gefertigt. Das erste Teilerzeugnis (10) weist eine funktionale Gruppe (10') und das zweite Teilerzeugnis (12) eine zweite funktionale Gruppe (12') auf. Um das Installationsgerät zu fertigen wird das zweite Teilerzeugnis (12) in eine Gehäuseaufnahmeöffnung (24) des ersten Teilerzeugnisses (10) eingesetzt.
摘要:
Déclencheur électromagnétique comportant, dans un boîtier (2) comprenant un socle (3) coiffé d'un couvercle (4), un circuit électromagnétique (5) comprenant une armature fixe (6) reposant sur le socle (3), ainsi qu'une armature mobile (7) susceptible d'ouvrir et de fermer le circuit électromagnétique (5), ladite armature fixe (6) étant prise entre le socle (3) et le couvercle (4). Selon un premier aspect, le socle (3) comprend une zone (72) déformable élastiquement, apte à s'enfoncer sous la pression de l'armature (6), les dimensions et la conformation du socle (3), du couvercle (4) et de l'armature fixe (6) étant aptes à permettre le serrage de l'armature fixe (6) entre le couvercle (4) et ladite zone déformable (72) qui la sollicite vers le couvercle (3) sous l'effet de son élasticité propre. Selon un deuxième aspect, le déclencheur électromagnétique, qui comporte une bobine (11) comprenant une carcasse (12) sur laquelle est enroulé un bobinage (13), ladite carcasse (12) étant enfilée sur l'armature fixe (6) et solidaire du boîtier (2), la carcasse (12) étant montée rigidement par rapport au boîtier (2) et flottante par rapport à l'armature fixe (6).
摘要:
An alloy on the basis of 40-55 wt. % nickel and iron becomes corrosion-proof by alloying it with 0.5-6 wt. % chromium. The surfaces of the components produced by said alloy are hardened by nitrating. The alloy is particularly useful for the use in relays and clockworks. The concentration of Ca, Mg and S together amounts to less than 0.009 wt. %.
摘要:
Trip system for an electric switch, comprising a yoke of magnetic material, consisting of a yoke base part, a first yoke leg and a second supporting yoke leg, said first and second yoke legs extending at a mutual spaced relation and in the same direction from the yoke base part, an armature from magnetic material bridging the free ends of the yoke legs and supporting pivotably by the supporting yoke leg, a permanent magnet provided such that its magnetic field lines extend through the yoke and the armature, a coil mounted on the yoke and spring means engaging the armature. The armature is held in a first position under influence of a magnetic field of the permanent magnet in opposite direction of the spring force of the spring means, in which the armature engages the free end of the first yoke leg. The armature may assume a second position under influence of the magnetic field developed by a current flowing through the coil and exceeding a predetermined limit value, in which surfaces facing to each other of the armature and the free end of the first yoke leg are spaced by a first air gap distance. The magnet is included in a second magnetic circuit formed by a yoke and the armature and having in the first position of the armature a magnetic resistance higher than that of the first magnetic circuit and which increases when the armature moves from the first to the second position.

1. Electromagnetic relay containing a magnetic circuit consisting of a yoke (16) with two vertical branches (20, 22) between bases (26, 28) whereof a permanent magnet is installed, and of a moving flap closing the magnetic circuit, together with a control circuit coiled on one (20) of the vertical branches (20, 22) of the yoke, characterized in that bases (28) of the said vertical branches (20, 22) are connected together by a horizontal magnetic shunt branch (34) parallel to the lines of force of the magnetic flux created by the permanent magnet.
