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 relay comprising a coil (1), a core (2), an armature (4), moveable and fixed contacts (5, 9), an armature spring (14), an armature spring support (13), as well as relay connections. The fixed contacts, the armature spring support and the relay connections are integrated as one piece in a three-dimensional printed circuit board. The invention also relates to a method for producing the relay.
Abstract:
The invention relates to a relay formed by a magnet system (1) which contains a wound coil body (2), an L-shaped core disposed axially therein and an L-shaped armature (4), in addition to a base (6) made of insulating material. Connecting elements (63, 64) protrude from the bottom side of said base, on which fixed (62) and moveable contact elements (61) are arranged. The moveable contact elements (61) are actuated by means of a sliding element (8) coupled to the armature. Fixing prolongations (34) are provided on the magnet system to fix the magnet system (1) to the base (6). Said prolongations engage in elongations (61) of the base (6) that are formed upwards and which firmly connect the magnet system (1) and the base (6). The open end of the transversal limb of the armature (4) is placed on the open end of the longitudinal limb of the core (3). The armature (4) is fixed by means of a U-shaped spring(5) surrounding the armature. Said spring is fixed to the longitudinal limb (41) of the armature by one of its arms. The second arm is inserted in a recess located between the coil body (2) and the core (3).
Abstract:
An electromagnetic drive unit (201) comprising a yoke (210) and a movable armature (215). The yoke (210) and the armature (215) have a matched shape so that, when the electromagnetic drive unit (201) is activated, the armature (215) is adapted to at least partially cross the yoke (210). The patent application comprises also an independent claim for an electromechanical switching device.
Abstract:
A balance-armature type polar relay (10) capable of assuring a sufficient insulation distance meeting the requirements of IEC60950 with the structure of itself when mounted on an electric communication line connecting equipment, wherein a maximum distance between one movable contact and one fixed contact capable of being brought into contact with each other during the travel of an armature is set at 1 mm or more, and at least one of the contact surfaces of the armature and the iron core polar surfaces of electromagnets opposed to the contact surfaces is formed as an inclined surface reducing an angle of opposed surfaces at the time of mutual contact as small as possible, whereby the armature passes, during the travel thereof, a position where each of the pair of contact surfaces faces the pair of corresponding iron core polar surfaces in parallel with each other.
Abstract:
The invention relates to an electromagnetic relay containing a base body (1) consisting of insulating material, an armature (21), said armature being located above said base body (1) in such a way that it can pivot, a contact spring device which is rigidly connected to the armature (21) by a covering (27) consisting of insulating material, a coil (3) and a core (31), said core being positioned axially in said coil. Two transversal torsion spring pins (25) extend out of the covering (27) in the area of the rotational axis of the armature. Said torsion spring pins (25) are aligned with their plate level perpendicular to the base level, said base level being determined by the floor of the base body (1), and are each attached to a middle contact connecting pin (12). Said middle contact connecting pin (12) projects out from the base body (1), perpendicularly to the base level.
Abstract:
An armature (10; 30; 50) for an electromagnetic actuator, the armature comprising an armature body (12; 32; 52), at least one electrically conductive member (14; 34; 54, 64) configured for cooperation with a magnetic field generator (110; 130; 150, 151) of an electromagnetic actuator, and a connection end(26; 46; 66) configured for connection of the armature to an apparatus operable by an electromagnetic actuator. The armature body (12; 32; 52) also comprises a cellular structure (13; 33; 53). The armature may form part of an electromagnetic actuator (100), which in turn may be a component in a switch device (200). The armature may be manufactured by a method comprising an additive manufacturing process step.
