    • The device includes two breaking areas formed at each side of a contact bridge carrying main contacts that can be separated from fixed contacts located in the breaking areas and fixed to main conductors. The main conductors each have shaped extensions in the break areas that are configured to cooperate with shaped extensions associated with arc collection parts positioned nearby. The shaping of the extensions and the spacing therebetween encourage a particular direction of arc migration relative to arcs created when the moveable contacts carried by the contact bridge are separated from the fixed contacts. Further, arc migration control is provided in the form of magnetic fields provided in each breaking area. Each arc collection part is connected through a shunt conductor and a single direction of current flow establishing component to make a direct electrical connection to the main conductor associated with the other area.
    • 该装置包括形成在承载主触点的接触桥的每一侧的两个断开区域,该触点可以与位于断裂区域中的固定触点分离并固定到主导体。 主导体各自在断裂区域中具有成形延伸部,其被构造成与定位在附近的电弧收集部件相关联的成形延伸部配合。 延伸部的形状以及间隔的间隔有助于当由接触桥承载的可移动触点与固定触点分离时,相对于产生的电弧产生电弧迁移的特定方向。 此外,电弧迁移控制以设置在每个断开区域中的磁场的形式提供。 每个电弧收集部分通过分流导体和电流流动建立部件的单一方向连接,以与与另一个区域相关联的主导体进行直接电连接。

    • A pole piece (14a) of the movable core (12) moves in an air gap (25a) between external (61) and internal (16) pole pieces. A pole flange (14b) of the same core (12) moves in an air gap (25b) between a portion (30b) of the external pole piece (61) and a magnetic lobe (36) which is in contact with this latter. A permanent return magnet (17) is disposed between the internal (16) and external (61) pole pieces. The magnet (17), the internal pole piece (16) andthe lobe (36) are maintained in a cage (60) of plastic material snap fastened by hooks (78, 80) on the external pole piece (61). Three cross pieces (75, 76, 77) connectingtwo longitudinal walls of the cage to each other, suitably separate the different magnetic components. The force of attraction of the magnet (17) prevents the pole pieces (16, 61) from leaving it.
    • 可动铁心(12)的极片(14a)在外部(61)和内部(16)极片之间的气隙(25a)中移动。 同一芯部(12)的极法兰(14b)在外部极靴(61)的部分(30b)与与其接触的磁性凸角(36)之间的气隙(25b)中移动。 永久性返回磁体(17)设置在内部(16)和外部(61)极片之间。 磁体(17),内部极片(16)和凸耳(36)保持在外部极片(61)上通过钩(78,80)固定的塑料材料保持架(60)中。 将笼子的两个纵向壁彼此连接的三个横档(75,76,77),适当地分离不同的磁性部件。 磁体(17)的吸引力防止极片(16,61)离开它。
