摘要： An electromagnetic relay includes a base, a fixed terminal, a fixed contact, a movable piece, a movable contact, a magnet, a base holder, and a case. The fixed terminal is supported by the base. The fixed contact is connected to the fixed terminal. The movable piece is supported by the base. The movable contact is connected to the movable piece and faces the fixed contact. The magnet exerts a Lorentz force on an arc generated between the fixed contact and the movable contact. The base holder is a separate body from the base. The base holder is attached to the base. The base holder is disposed in at least a direction in which the Lorentz force acts with respect to the base. The case is attached to the base holder.

摘要： Provided is a relay having a structure for preventing deformation of a movable spring when it is caulked. A yoke of the relay has a protrusion for caulking inserted in the movable spring, and a bulge portion adjacent to the protrusion and having a height lower than a height of the protrusion. By providing the bulge portion to the yoke, the dimensional change in the caulking direction of the movable spring when the movable contact is caulked can be reduced.

摘要： A polarized electromagnetic relay includes a base, an electromagnet with a coil and a pair of pole pieces extending perpendicularly from the end of said coil, a balanced armature and spring system which when actuated pivots between two fixed contact points and a permanent magnet inducing the same magnetic poles in both of said pole pieces and providing an opposite pole in closely adjacent relationship to the central portion of the armature. A movable contact spring is fixedly connected to the armature, said spring forming contact arms at either armature end portion and a pair of torsion pivot arms extending transversely in opposite directions along the pivot axis of said armature, the distal ends of either pivot arm being fixedly connected to a support extending on either side of the armature from a coil bobbin. Further, a flexible movable braid connects the movable contacts on said movable spring to each other and to a movable contact terminal. Two identical coils wound in a common direction are provided as the means for actuation. Armature transfer will occur by either applying a voltage pulse across the appropriate coil, or by toggling the voltage pulse polarity across the two coils connected in series.

摘要： A relay comprises a spool with flanges (2, 3), an angular yoke (7) and an angular armature (9) positioned in front of the free end of the yoke (7). A contact element (8) attached to the free end of the yoke is provided for contacting of the relay spring (10c), which is connected with said armature. During the assembly process an armature assembly including an armature (9), connecting element (8) and leaf spring (10) is preassembled and subsequently mounted as a single unit onto the yoke (7). Since all connecting elements are connected with the spool or with the yoke, additional soldering to the base is not required. This physical configuration enables a fully automatic production of the relay.

摘要： An AC current electromagnetic relay is disclosed herein. The relay comprises a U-shaped armature with arms connected by a web and a generally E-shaped yoke with an elongated center leg and shortened side legs extending from a common base, the elongated center leg serving as a core around which a coil and a shading ring are disposed. The U-shaped armature is placed on the yoke with the free end edges of the arms being pivotally supported on the respective side legs of the yoke, so that upon the energization of the coil the armature is pulled toward the yoke and abuts against the respective free end portions of the side legs and the center leg, such free end portions being cooperative to define apexes of a triangle. Thus, a three-point contact can be attained between the armature and the yoke. With this arrangement of the three-point contact, the armature is allowed to abut simultaneously against all the three contacting faces at the free end portions of the respective legs, even if these contacting faces are out of exact alignment in the same plane, whereby effecting stable contact between the armature and the yoke. Accordingly, the relay can assure stable and intimate contact of the armature with the yoke for preventing chattering and beating at the time of energizing the coil, while allowing the employment of the yoke having possible misalignment of the contacting faces at the free end portions of yoke.
摘要翻译：本文公开了一种AC电流电磁继电器。继电器包括具有臂的连接的U形电枢和具有细长的中心腿的大致E形的轭和从公共基底延伸的缩短的侧腿，细长的中心腿用作芯，线圈和设置遮光环。 U型电枢放置在磁轭上，臂的自由端边缘被枢转地支撑在磁轭的相应的侧支腿上，使得当线圈通电时，电枢被拉向磁轭并抵靠在磁轭上侧腿和中心腿的自由端部，这样的自由端部协作地限定三角形的顶点。因此，可以在电枢和轭之间实现三点接触。通过这种三点接触的布置，即使这些接触面在同一平面上不准确对准，也可以使衔铁同时抵靠在各个腿的自由端部处的所有三个接触面，从而实现衔铁与轭之间的稳定接触。因此，继电器可以确保电枢与磁轭的稳定和紧密的接触，以防止在励磁线圈时发生颤动和跳动，同时允许使轭具有在轭的自由端部处的接触面可能的未对准。

摘要： A relay is provided for reversing the direction of current to an electric motor and providing for dynamic breaking when power is disconnected. The contacts are cantilevered from a pivoting support driven electromagnetically. Mounted inwardly of the cantilevered contacts, are a pair of cantilevered springs. Each cantilevered spring is adjacent to, and associated with, a respective cantilevered contact. When the relay is energized, displacing one of the cantilevered contacts, a respective cantilevered spring is deflected against the cantilevered contact to provide a force additional to the force induced by the cantilevered contact support. Additionally, a fulcrum is provided for supporting pivotal movement of an armature supporting the cantilevered contacts, and which is combined with the magnetic flux path of the relay.

摘要： An electromagnetic switching device, such as a wire spring relay, includes a coil having one leg of a substantially U-shaped core inserted into a central bore of the coil. An L-shaped armature is hinged for movement to the core so that pole faces of the armature mate with associated pole faces of the core when an operating potential is applied to the coil. A plurality of groups of parallel wires are embedded in and extend from a plastic support block which is attached to one leg of the core. The ends of the wires are spaced apart and extend through openings in a card which is attached to the movable armature and a restoring spring. When the switching device is operated, the armature is moved so that the pole faces thereof mate with the associated pole faces of the core whereby the card is moved against the biasing of the restoring spring to bring together selected wires of the parallel groups of wires to facilitate electrical connections in external circuits connected to the opposite ends of the selected wires.
