Definitions
- the invention relates to an electromagnetic relay
- a base body made of insulating material, which defines a base plane with its bottom side, and in which connection tracks for fixed contact elements and connection elements for fixed and movable contact elements are molded,
- a pivotable anchor arranged above the base body, the axis of rotation of which runs parallel to the base plane,
- a contact spring arrangement which is firmly connected to the armature via an insulating material sheath and which corresponds to the fixed contact elements of the
- Basic body cooperates and in the region of the armature axis of rotation has two transverse torsion spring bars protruding from the casing, the contact springs of the contact spring arrangement and the torsion spring bars being made from a common circuit board,
- a polarized relay is known from EP 0 197 391 B2, the armature of which is carried by a pair of contact springs.
- the contact springs can be moved together with the armature and in their central region are each equipped with a transversely extending rotating arm which is fixedly connected to a contact piece on a base body.
- the torsion arms are integrally formed on the contact springs and represent elastic torsion elements with limited deformability.
- torsion spring bars standing horizontally there is a disadvantage in that the torsion spring bars To a not insignificant extent, vertical forces are also exposed, as a result of which a constant accuracy of the air gaps between armature and magnet or fixed and work contacts is restricted.
- the aim of the invention is to provide a reliable and low-wear armature bearing for a relay of the type mentioned, so that a higher accuracy of the armature movement is guaranteed in order to increase the reliability and service life of the relay.
- Other objectives concern the miniaturization of the design and the reduction in the number of necessary relay components.
- simple and quick alignment of the armature-spring assembly in the vertical direction relative to the fixed contacts and the pole pieces is sought, which makes it easier to set the contact pressure, armature stroke and response voltage during assembly. It is also important to store the armature in a position that is as immovable as possible relative to the fixed contacts and the other elements of the magnet system, in order to ensure both high shock resistance and constant settings of the relay parameters, such as armature stroke, contact pressure and response voltage.
- the torsion spring webs are aligned with their sheet metal plane perpendicular to the base plane and are each fastened to a center contact connecting pin protruding from the base body perpendicularly to the base plane.
- the free ends of the torsion spring webs are connected at right angles from their sheet metal plane connecting surfaces. These connecting surfaces are formed in one piece on the torsion spring webs and lie against connecting surfaces of the center contact connecting pins.
- the torsion spring bars are bent at right angles and widened at their free ends in the area of the connection surfaces. This contributes to good accessibility of the fastening points and to extended adjustment options for the armature-spring assembly.
- connection surfaces are preferably attached to the center contact pins by resistance welding or laser welding. Due to the vertical, mutually aligned connecting surfaces, the armature-spring assembly can be inserted from above into the base body or into a base. After reaching a desired contact distance, the armature-spring assembly is attached to the base body or base.
- the relay In a polarized embodiment of the relay with at least one permanent magnet arranged between the pole pieces parallel to the coil axis and which produces a polarization of the same name at the ends of the pole pieces, it can be mechanically targeted by fastening the armature-spring assembly in an already deflected position Preset a monostable behavior of the relay. This is possible, for example, by choosing a smaller contact spacing on the normally closed contacts than on the normally open contacts.
- the torsion spring bars and the connecting surfaces adjoining them grip around the contact connection pins, as a result of which a more favorable position is provided for the attachment of welding spots on the connection surfaces of the torsion spring bars and center contact connection pins.
- the armature is preferably an deformable, vertically standing pin of the sheath of the contact spring arrangement with the contact springs and the sheath to form an anchor. Spring assembly connected. The anchor can be plugged onto the pegs of the casing. The armature is firmly connected to the casing and the contact springs by deformation of the pins.
- the armature in the region of the armature bearing has a bearing web which is formed parallel to the armature axis of rotation.
- connection tracks for the fixed contact elements are made from a common circuit board, the associated connection elements being formed by vertically bent connection tabs on the circuit board.
- a base of the relay is formed by the base body, which receives the armature-spring assembly, the coil being arranged in an insulating sheath above the base.
- a compact relay housing is formed by the covering of the coil, a frame pushed over the base and the base of the base.
- FIG. 1 shows a relay according to the invention in a partially sectioned perspective illustration
- FIG. 2 shows a base and an armature-spring assembly of the relay according to FIG. 1 in an exploded view
- FIG. 3 shows a contact spring arrangement and center contact connections of the relay according to FIG. 1
- FIG. 4 shows the contact spring arrangement with the associated sheath.
- FIG. 1 shows a relay, the housing of which is formed by the bottom side of a base body 1 or base, a frame 5 pushed over the base body 1 and a coil covering 6.
- a relay the housing of which is formed by the bottom side of a base body 1 or base, a frame 5 pushed over the base body 1 and a coil covering 6.
- the winding connection elements 34 are embedded in the base body 1 encompassing flange extensions of a coil body.
- An armature-spring assembly 2 is located above the base body 1 and below a coil 3
- armature 21 In order to reduce the magnetic resistance between armature 21 and a permanent magnet 33 arranged above it between two pole shoes 32, a transverse bearing web 22 is formed on armature 21 in the region of the armature axis of rotation.
- the permanent magnet 33 generates a polarization of the same name at the ends of the pole shoes 32, which connect vertically downward to the free ends of a core 31 arranged axially in the coil 3, as a result of which two bistable working positions of the armature 21 are possible.
- a corresponding oblique orientation of the armature-spring assembly 2 can achieve monostable behavior for the relay.
- connecting tracks 14 for fixed contacts are made from a common circuit board. clock 16 embedded.
- the fixed contacts 16 are welded onto the connecting tracks 14.
- the contact connection elements 11 are formed by downwardly bent connection tabs 5 (see also FIG. 3) of the common circuit board for the connection tracks 14.
- the center contact connection pins 12 are formed by connection tabs bent upwards, while the connection elements 11 of the center contacts are bent downwards and protrude through the bottom side of the base 4.
- the armature-spring assembly 2 contains two separate, parallel contact springs 23 which have switch contacts welded on at their ends.
- the contact springs 23 are prefabricated from a common circuit board and surrounded by an insulating sheath 27. Since the connection compartments 26 of the torsion bars 25 and the connection compartments 13 of the center contact connection pins 12 abut one another in a plane perpendicular to the base plane, the armature-spring assembly 2 can be inserted into the base 4 from above during assembly. When a desired contact distance is reached, the connection areas 26 are welded onto the connection areas 13 of the center contact connection pins 12.
- the spring sheathing 27 has deformable fastening pins 28 standing vertically upwards, onto which the armature 21 is attached. By deforming these fastening pins 28, the armature 21 is firmly connected to the contact springs 23 and the spring sheathing 27 to form an armature-spring assembly 2. Furthermore, the contact springs 23 are slotted at their free ends, which increases their flexibility.
- the formation of the vertical torsion spring bars 25 is illustrated by Figure 3.
- the leaf springs 23 have parallel side arms in their central region, at the free ends of which one is at right angles to the outside guided torsion spring bar 25 connects.
- the torsion spring webs 25 are bent upwards, which produces the orientation of their sheet metal plane perpendicular to the base plane.
- the contact springs 23 are surrounded in their central region to such an extent that only the free end sections of the contact springs 23 and the vertical torsion spring bars 25 protrude from the casing 27 (see FIG. 4).
- leaf spring-like spring webs 25 are subjected to torsional loads, a higher spring rate can be achieved in this way regardless of the thickness of the contact springs 23 than with spring webs subjected to bending stress. Due to the high rigidity of the torsion spring bars 25 in the vertical, there is a largely constant distance between the armature 21 and the permanent magnet 33. In particular, the vertical torsion spring bars 25 result in a very high shock resistance of the relay.
- the desired contact distance can be set quickly and easily.
- the desired armature stroke can be easily adjusted during assembly in that the coil 3 with the permanent magnet 33 can be pushed onto the base assembly until the desired armature stroke is set.
- the coil 3 clamps on the base 4 with the flange body sets of the coil body directed downward.
