A switching device structure comprising a top magnet, a bottom magnet, and a movable member disposed between the top and bottom magnets, the movable member having an electromagnet positioned thereon, the electromagnet comprising a plurality of laminated layers, the layers including a layer bearing an iron core and a number of armature layers which establish electrical conductor windings around the iron core.
Abstract:
Methods and systems of assembling and making laminated electro-mechanical systems and structures are described. A plurality of structural layers are formed that include at least one structural layer having a movable element formed therein. The plurality of structural layers are stacked and aligned into a stack. Each structural layer in the stack is attached to an adjacent structural layer of the stack.
Abstract:
The present invention discloses a laminated-based electromechanical device and a method of fabricating laminate-based electromechanical devices. The device includes two or more layers of laminate bonded together to form a unitary laminate structure. The layers of laminate include a layer of organic dielectric material that may have at least a portion of one layer of electrically conductive material adherent thereto. The layers of organic dielectric material are bonded to form a unitary laminate structure through a process of lamination. The structures that make up the electromechanical device may be formed either before or after bonding. In particular, the various electromechanical structures that make up the electromechanical device are formed from the layers of organic dielectric material and the layers of electrically conductive material adherent thereto using a predetermined sequence of additive and subtractive fabrication techniques.
Abstract:
The relay and the method for producing said relay are characterized by their simplicity in terms of production. Instead of using different materials for the coil body, the core device and the elements of the load circuit, the ferromagnetic or electrically conductive metals are replaced at least in part by plastic materials to which ferromagnetic or electrically conductive properties are added. In one embodiment, the whole relay consists of plastic parts except for the winding, which have been produced in a multicomponent injection molding process.
Abstract:
A coil form (1) is injection moulded to form the base body of the relay. At least one fixed contact carrier (3,4), one contact-spring contact pin (5) and coil contact pins (9,10) embodied as wire sections in the form of drawn semi-finished products are introduced into the mould and extrusion-coated. The core (16) can also be embedded into the material of the coil form (1) if so desired. This dispenses with assembly processes involving the abrasion of plastic particles which can later become deposited on the contacts. All connector pieces can be mounted in a cost-effective manner in the injection mould, requiring as little material as possible by virtue of the fact that there is no wastage when the semi-finished wires are separated.
Abstract:
A method of constructing an encapsulated relay is described in which the relay includes an intensely magnetised actuator/armature formed from a chromium/cobalt/iron alloy after fabrication is assembled and encapsulated in a clean environment before being magnetised and heat treated. A relay construction which includes such an actuator/armature is described in which the relay components are accurately located on an insulating base which itself is moulded out of a sheet of conductive material so as to leave protruding lugs which can be bent upwardly and downwardly to form (or provide supports for) some of the component parts of the relay.
Abstract:
The invention relates to an electrical component (1), in particular a piezoelectric multilayer component, comprising at least one outer contact (7) having a first metallization (8) and a second metallization (9), wherein the metallizations (8, 9) are baked in, and wherein the second metallization only partially covers the first metallization. The metallization can be frame-shaped. The first metallization and the second metallization may have a different degree of wettability with solder material. The invention further relates to a method for establishing an outer contact.
