    Abstract: An electromagnetic relay enables current to pass through switch termini and comprises a coil assembly, a rotor or bridge assembly, and opposing, balanced switch assemblies. The coil assembly comprises a coil and a C-shaped core. The coil is wound round a coil axis extending through the core. The core comprises core termini parallel to the coil axis. The bridge assembly comprises a bridge and a pair of actuators. The bridge comprises medial, lateral, and transverse field pathways. The actuators extend laterally from the lateral field pathway. The core termini are coplanar with the axis of rotation and received intermediate the medial and lateral field pathways. The actuators are cooperable with the switch assemblies. The coil creates a magnetic field directable through the bridge assembly via the core termini for imparting bridge rotation about the axis of rotation. The bridge rotation displaces the actuators for opening and closing the switch assemblies.

  • Patent number: 7477119
    Abstract: An electromagnetic relay includes an electromagnetic unit operable so as to generate a magnetic field perpendicular to a bottom wall of a housing when excited such that an actuating plate pivots from a releasing position to a pushing position, where a magnetically-attractable end portion of the actuating plate is attracted by the electromagnetic unit and where an actuating end portion of the actuating plate moves toward a first conductive plate, thereby driving a pushing block to move a resilient end portion of the first conductive plate toward a second conductive plate. Hence, first and second contacts on the first conductive plate contact electrically and respectively third and fourth contacts on the second conductive plate.

Fixed contacts are provided for each of the terminals of the two circuits and each of two sets of a pair of movable contacts in positions corresponding to these is supported by two both-end-supported movable springs. An insulation sheet and a press spring are overlapped over the two movable springs and disposed as a bridge. A pair of tongues ate formed on the press spring by a Z-character shaped cut and by an armature pressing their tips, the insulation sheet and press spring transforms to an upward concave shape, the two movable springs bend and are taken in inside while inclining and the movable contacts touch the fixed contacts while sliding (see FIG. 6C).

  • Patent number: 7053738
    Abstract: A relay and a process for producing a relay are described, three contact pins being provided for the relay. The three contact pins are preferably manufactured from a stamping and are fixed together as a contact stamping with respect to a yoke through insertion into a base. As a result of the use of a contact stamping with the three contact pins connected rigidly to one another, adjustment and handling of the three contact pins during production of the relay is relatively simple.

  • Patent number: 6940375
    Abstract: An electromagnetic relay makes it difficult for deformation due to impact force to easily occur even when bending work is applied to a contact plate. A coil block is put on a base and a moving contact plate and fixed contact plates are so juxtaposed as to oppose one another. The moving contact plate is constituted by a contact-fitting portion to which a moving contact is fixed, a push-in fixing portion which is pushed in and fixed to the base and from which terminal portions extend, and a connection portion for connecting the contact-fitting portion and the push-in fixing portion. The connection portion has a width smaller than those of the contact-fitting portion and the push-in fixing portion.
