| 20090039990 | Magnet switch with magnetic core designed to ensure stability in operation thereof - A magnet switch which may be employed in automotive engine starters is provided. The magnet switch includes a stationary magnetic core made up of a disc assembly and a core body. The disc assembly is made of a stack of annular plate members superposed on each other. Each of the plate members has an opening through which a terminal lead of a magnetic coil extends. The core body has a boss with an edge which is plastically deformed outwardly in the radius direction thereof or staked to create an elastic nip which retains the stack of the plate members firmly on the core body. This structure ensures the joint between the disc assembly and the core body to withstand mechanical impact exerted on the magnetic core and stability in operation of the magnet switch without increasing a total production cost of the magnetic switch. | 02-12-2009 |
| 20090261928 | RELAY - A relay includes a contact point block having a support shaft with both ends spanning a contact point base, a plunger having a movable contact at a lower end thereof, and a movable iron piece configured to drive the plunger and to have a plate spring. The relay also includes an electromagnetic unit and a base block having a fixed contact point at a position opposite to the movable contact point. The movable iron piece is supported on the supporting shaft. The plunger is inserted through an operation hole of the contact point base. Upper and lower surfaces of the contact point block are held by the electromagnetic unit and the base block. The electromagnetic unit directly fixes the iron core to an upper surface of the contact point base. | 10-22-2009 |
| 20130257568 | CONTACT SWITCHING DEVICE - An object of the invention is to provide a contact switching device that prevents scattered objects caused by arc from coming in, so that the scattered objects do not disturb operation of a movable shaft. For this, there is provided a contact switching device in which a movable iron core ( | 10-03-2013 |
| 20130335175 | CONTACT MECHANISM AND ELECTROMAGNETIC CONTACTOR USING THE SAME - A contact mechanism where a shape of at least one of a fixed contactor including a pair of fixed contact portions and a movable contactor including a pair of movable contact portions capable of contacting with and separating from the pair of fixed contact portions is set to a shape that generates a Lorentz force resisting electromagnetic repulsion in a contactor opening direction generated between the fixed contact portions and the movable contact portions when a current is applied, has the fixed contactor and the movable contactor being inserted in a current path. Magnetic bodies are disposed on at least one of the fixed contactor and the movable contactor for suppressing a force driving arcs, which are generated between the pair of fixed contact portions and the pair of movable contact portions, to the fixed contactor on the opposite side. | 12-19-2013 |
| 20140015627 | RELAY - A relay includes two stators each having a fixed contact, and a movable element having movable contacts. Each of the stators includes a stator proximity plate portion adjacent to the movable element, and the movable element includes a movable element proximity plate portion adjacent to the stators. A direction of current flowing in the stator proximity plate portions is set to be same as a direction of current flowing in the movable element proximity plate portion to generate an inter-plate attraction force for attracting the movable element proximity plate portion onto the stator proximity plate portions. The movable element proximity plate portion is biased by the inter-plate attraction force toward a direction for bringing the movable contacts into contact with the fixed contacts. | 01-16-2014 |
| 20140145803 | ELECTROMAGNETIC RELAY - An electromagnetic relay, in particular a motor vehicle relay, contains a magnet yoke, a relay coil, a hinged armature which is pivotable about an axis of rotation and on which a moving contact, as working or switchover contact, is retained relative to at least one fixed contact. A piezo actuator is provided, which keeps the working or switchover contact closed when the relay coil is de-energized as a result of the actuation of the piezo actuator. | 05-29-2014 |
| 20150294824 | CONTACTOR - A contactor includes a contact portion and an actuation portion. The contactor further includes a keeping portion. The keeping portion includes a capacitor structure and uses an electrostatic force between opposite plates of the capacitor structure to keep the contact portion in a contact state or a disconnection state. The electrostatic force generated by an electrostatic latch is used to keep the contactor in a switched-to static state. The contactor has reduced energy consumption in the static state, is convenient to manufacture, and has a low cost. | 10-15-2015 |

| 335149000 | Plural coils | 1 |
| 20140327502 | ELECTROMAGNETIC ACTUATOR - An electromagnetic actuator for operating at least one movable contact of a switch into a switched-on position or a switched-off position, the actuator having: a static pole body; a movable pole body movable relative to the static pole body; a first magnetic circuit with a first coil for making the movable pole body and the fixed pole body move towards each other to a switched-on position and a second coil for making the movable pole body and the fixed pole body move away from each other to a switched-off position; and a second magnetic circuit with a permanent magnet and a retaining plate to keep the static pole body and the movable pole body in the switched-on position; first spring unit for urging the static pole body and the movable body away from each other; wherein the first and second magnetic circuit are arranged concentrically. | 11-06-2014 |
