    摘要: An electromagnetic relay has a casing of electrically insulative material which is divided by an insulating partition into a coil space for receiving an electromagnet and a switching space for receiving a contact assembly. An armature is magnetically coupled to the electromagnet and is operatively connected to the contact assembly for switching contact operation thereof in response to energization of the electromagnet. The partition extends along the entire length of the electromagnet without leaving any communication path between the coil space and the switching space, such that the electromagnet in the coil space can be insulatively separated from the contact assembly in the switching space within the length of the electromagnet.

    摘要: A polarized electromagnetic actuator device advantageous for single-stable armature operation comprises an armature pivotally supported for movement between two different angularly displaced positions about a pivot axis and an electromagnet with a pair of opposed pole members extending toward the ends of the armature on either side of the pivot axis. Disposed between the free ends of the opposite pole members is a bar-shaped three-pole magnetized permanent magnet which is magnetized to have end poles of the same polarity at the longitudinal ends and a center pole of the opposite polarity intermediate the ends, producing first and second flux paths opposing to each other and extending between the respective end portions of the permanent magnet and the adjacent end portions of the armature. The center pole is offset from the pivot axis of the armature to provide at a correspondingly offset portion therefrom between the armature and the permanent magnet a common flux path through which the first and second flux paths extend in the same direction, whereby producing a torque on the armature tending it to rotate about the pivot axis toward the one of the two angularly displaced positions.

    摘要: A polarized electromagnetic relay includes a flat-shaped armature pivotally supported at its center, an electromagnet with a pair of pole members extending toward the armature ends on either side of the center pivot axis, and a three-pole magnetized permanent magnet bridging between the pole members in generally parallel relation with the armature. A pair of movable contact springs extends along the lateral sides of the armature and joined at its center portion to the armature to be movable therewith. Integrally formed with each movable contact spring is a pivot arm which extends transversely from the center thereof and is fixedly secured to a relay casing. The pivot arm defines itself a resilient torsion element of limited deformability by which the armature is supported on the relay casing and is permitted to pivot about the center pivot axis for movement between the two angular positions.

    摘要: In an electromagnetic relay, an armature block serving to actuate contact springs includes a pair of armatures and a permanent magnet disposed therebetween to magnetize the armatures to opposite polarities. Pole ends of a yoke carrying the excitation flux created by the relay coil extend between free ends of the armatures. The armature block is suspended by means of a resilient arm integrally formed with the block at one side thereof and having its outer end fixed to a bearing portion, so that a rocking motion of the armature block is achieved by a flexing motion of the resilient arm.

    摘要: A polarized electromagnetic relay is designed to have a minimum height as less as that of an electromagnet block constituting one major part of the relay. The relay includes a base which is formed to receive the electromagnet block and to have a set of fixed contacts. The electromagnet block includes a generally U-shaped yoke with a pair of opposed legs connected by a center core and at least one excitation coil wound around the center core. An armature block is mounted within the base together with the electromagnet block and comprises an elongated armature extending over the opposed pole legs and pivotally supported for movement between first and second positions about a pivot axis. The armature block carries a movable contact for contact selectively with one of the fixed contacts in response to the armature movement between the first and second positions. The armature is magnetically coupled to the pole legs by means of a permanent magnet such that the armature block responds to polarity change in the current energizing the excitation coil to move between the first and second positions. The permanent magnet is disposed in the bottom portion of the base within the plane of the pole legs. The armature block is disposed above the permanent magnet in such a manner that the armature block and the permanent are stacked within the height of the electromagnet block.

    摘要: An optical switch switches the light path between collimate lenses optically coupled to the ends of corresponding optical fibers by the advancing and retracting movements of a prism. The prism comprises an electromagnetic driver having an armature arranged to hold the prism, a coil block for driving the movement of the armature by use of magnetic actions and a leaf spring. The leaf spring mainly includes four parallelly extending spring strips fixedly joined at one end to a body and at another end to the armature to thus spatially hold the armature and the prism for linear movement. The electromagnetic driver and the prism are disposed next to each other along the moving direction of the armature. The armature and the prism can be linearly moved at a right angle to the light path between the lenses when the optical switch is in action. This allows the prism to be linearly moved, and the device can be minimized in overall size.
