Abstract:
An orbiting relay assembly may be provided that has one or more switches. The switches may be provided with electrical contacts. An actuator such as an electromagnetic actuator may rotate guiding structures such as a rotating yoke about a rotational axis. The guiding structures may have portions that receive movable electrical coupling structures such as metal balls or cylinders. There may be multiple movable electrical coupling structures in a relay. The electrical coupling structures may be distributed radially outwards from the rotational axis, may be distributed circumferentially about the rotational axis, or may be distributed axially parallel to the rotational axis. The guiding structures may be configured to place the switches in one or more different operating states by moving the metal balls or other movable electrical coupling structures about the rotational axis.
Abstract:
The invention relates to an electromagnetic control device for the opening and closing of a mechanical element, particularly a valve of an internal combustion engine. The positioning of the mechanical element in at least one position (open or closed) is achieved by the action of at least one solenoid (90) acting on a plate controlling the position of the mechanical element. The device has at least two gaps which are closed by the plate on the positioning of the mechanical element in at least one position, the plate being mounted to rotate such that the axis of rotation of the plate is between the two gaps. The device also has at least one permanent magnet (99b) to polarize the device such as to hold the plate in at least one position in the absence of current through the solenoid (90), said permanent magnet (99b) not being crossed by the principal magnetic flux (92) of the solenoid (90).
Abstract:
The invention concerns an electromagnetic device of a switching apparatus comprising a mobile armature (20) rotating in a fixed frame (10) between two inactive and active positions, at least a permanent magnet (15, 15null) mounted in the fixed frame, at least a coil (24, 25) mounted in the mobile armature and control means (40) capable of delivering a control current (44) into the coil. The mobile armature is monostable; in inactive position, a lever (30) actuated by the mobile armature brings about the separation between the fixed contacts (31) and the mobile contacts (32) of the apparatus. In active position, the lever is released from the mobile armature and a spring (35) presses the mobile contact on the fixed contacts.
Abstract:
A microwave C-, T- or S-switch has an actuator of circular shape that is rotated by a suitable motor. Each conductor path of the switch contains a connector having two positions, one position connecting the conductor path and a second position interrupting the conductor path. The conductor paths and connectors are enclosed within a housing and a pin is mounted on each connector and extends outside of the housing through a suitable opening. Each pin is spring-mounted so that the conductor path is connected when the pin is depressed and interrupted when the pin is released. The actuator is shaped and mounted to override the pins, the actuator containing one or more ridges and one or more indentations. When a ridge overrides a pin, the pin is depressed and the conductor path is connected. When an indentation overrides a pin, the pin is released and the conductor path is interrupted. By properly arranging the size and location of ridges and indentations on the actuator, the conductor paths can be connected or interrupted simply by rotating the actuator through two or more positions. The switch achieves mass and volume savings over previous switches. Also, the switch is simple and relatively inexpensive to manufacture.
Abstract:
A relay for wideband signals is provided having a rotor which includes a permanent magnet structure, an armature, and a microstrip pattern for selectively engaging microstrip patterns on a substrate and having a stator which includes an electromagnet. To minimize wear, while maintaining high frequency performance, the rotor is raised, rotated, and lowered by a stator or electromagnet onto the new position relative to the substrate microstrip pattern. In a first stable state the electromagnet is inactive and the rotor engages the substrate microstrip pattern in a first position. To place the relay in a second stable state, the electromagnet is energized which simultaneously attracts the armature, raising the rotor, as well as repulsing the permanent magnet structure. The rotor then rotates to the desired second position and the electromagnet is inactivated. The rotor then lowers and engages the substrate microstrip pattern in a second position.
Abstract:
The improved relay includes two hollow coil bodies which are in axial alignment on a common base. A beam rotating armature extends through the inside of the coil bodies in the axial direction. A bearing element composed of an insulating material is provided in the central portion of the armature, the bearing element including center contact springs which are embedded parallel to the armature. By means of the bearing element, the armature is embedded by means of neck portions in the base and in a sole plate which connects the two coil bodies. The two ends of the armature form working air gaps with a pair of yokes, the yokes being angularly positioned and being actuated by two permanent magnets which lie above the coil bodies.
Abstract:
A relay includes a movable block, a base substrate, and a coil block. The movable block is provided rotatably around a rotational axis of the movable block. The movable block includes a plurality of sliders. The base substrate is disposed opposite the movable block in the rotational axis direction of the movable block, and contacts the sliders. The base substrate includes a plurality of contactors that come into contact with the sliders. The coil block includes a coil that generates electromagnetic force by electric conduction to rotate the movable block with respect to the base substrate. As the movable block rotates, continuity is switched between the sliders and the contactors.
Abstract:
A bistable relay and a bistable actuator are provided. The bistable actuator includes a magnetic latching mechanism and an electromagnet. The magnetic latching mechanism includes a rotation shaft, a pillar-shaped permanent magnet, a columnar hollow magnetic conductor and two shells, and operates between a first and second stable states. The columnar hollow magnetic conductor surrounds the pillar-shaped permanent magnet wrapping the rotation shaft, and maintains a gap with the pillar-shaped permanent magnet. The electromagnet is connected to the columnar hollow magnetic conductor for driving the pillar-shaped permanent magnet to rotate, so as to switch the magnetic latching mechanism to the stable state. During a process that the magnetic latching mechanism is switched to the stable state, the rotation shaft rotates synchronously along with the magnetic latching mechanism to drive an impact system to move relative to a contact system, so as to contact or disconnect the contact points.
Abstract:
A latching relay has a fixed iron core including an exciting coil wound around an intermediate portion and a magnetic pole piece at two ends; movable iron pieces sandwiching a permanent magnet between two bar-shaped iron pieces disposed in parallel with each other, and are fixed with a holder; and a switchable electrical contact portion. The fixed iron core and the movable iron pieces are disposed facing each other to insert each of the magnetic pole pieces on two sides of the fixed iron core to be spaced apart in a space between the two bar-shaped iron pieces of two end portions of the movable iron pieces. The movable iron pieces are supported pivotally in a direction in which the two bar-shaped iron pieces are aligned. The movable iron pieces are linked to the electrical contact portion, and the movable iron pieces perform a switching of the electrical contact portion.
