Definitions
- a polarized relay is known from EP 0 197 391 B2, the anchor of which is carried by a pair of contact springs.
- the Contact springs are movable and in together with the armature their middle area each with a transversal extending rotating arm, which is fixed with a Contact piece is connected to a base body. Are there the rotating arms are integrally formed on the contact springs and provide elastic torsion elements with limited deformability
- there is a horizontal torsion spring bar a disadvantage in that the torsion spring bars to a not insignificant degree also vertical forces exposed, which ensures consistent accuracy the air gap between anchor and magnet or fixed and Work contacts is restricted.
- the aim of the invention is to create a reliable and low-wear armature bearing for a relay of the type mentioned so that a higher accuracy of Anchor movement is guaranteed to reliability and increase the life of the relay.
- Other objectives concern the miniaturization of the design and the reduction the number of necessary relay components.
- a simple one and quick alignment of the armature-spring assembly in the vertical direction relative to the fixed contacts and the Pole shoes aimed at, making the setting during assembly relief from contact pressure, armature stroke and response voltage is. It is also important to anchor the anchor in one if possible immovable position relative to the fixed contacts and the other elements of the magnet system to store both a high shock resistance as constant settings of the Relay parameters such as armature stroke, contact pressure and response voltage, to ensure.
- the free Ends of the torsion spring bars at right angles from their sheet metal level bent connecting surfaces. These connecting surfaces are integrally formed on the torsion spring bars and lie on connecting surfaces of the center contact pins.
- the torsion spring bars are in the area of the connection surfaces bent and widened at right angles at their free ends executed. This contributes to good accessibility the attachment points and extended adjustment options the armature-spring assembly.
- the attachment of the Connection surfaces on the center contact pins preferably by resistance welding or laser welding. Through the vertical, aligned to each other The anchor-spring assembly is the connecting surface during assembly can be inserted from above into the base body or into a base. After reaching a desired contact distance the anchor-spring assembly is attached to the base body or base.
- a polarization of the same name can be created by Fastening the armature-spring assembly in an already deflected one Position in a mechanical way targeted a monostable Preset the behavior of the relay. For example, this is possible by choosing a smaller contact distance on the normally closed contacts than on the normally open contacts.
- the torsion spring bars encompass and the adjoining connecting surfaces the contact pins, creating a more convenient position for attaching welding spots to the connecting surfaces the torsion bars and center contact pins given is.
- the anchor is preferably via deformable, vertically standing pin of the sheath of the contact spring arrangement with the contact springs and the casing to form an armature-spring assembly connected.
- the anchor is on the tenon of the Cladding attachable. Due to the deformation of the pegs Anchor firmly connected to the casing and the contact springs.
- the anchor points in the area of the Anchor bearing formed parallel to the axis of rotation of the anchor Footbridge on. As a result, the magnetic resistance between the anchor and neighboring elements of the magnet system reduced, resulting in a reduction in losses in the magnetic circuit results. This is a further reduction in power consumption of the relay possible.
- the connecting tracks for the fixed contact elements made from a common board, whereby the associated connection elements by vertically bent Connection tabs of the board are formed.
- a base of the relay is formed by the base body, which the armature-spring assembly receives, with the coil above the base is arranged in an insulating jacket. By wrapping the coil, one pushed over the base
- the frame and the bottom of the base is a compact Relay housing formed.
- Figure 1 shows an inventive relay in a partially sectioned perspective view
- Figure 2 shows a base and an armature-spring assembly of the relay 1 in an exploded view
- Figure 3 shows a contact spring arrangement and center contact connections of the relay according to Figure 1 and
- Figure 4 shows the contact spring assembly with associated sheath.
- a relay can be seen, the housing through the Bottom side of a base body 1 or base, one over the Base body 1 pushed frame 5 and a coil cover 6 is formed.
- the winding connection elements 34 are in the base body 1 encompassing flange extensions Coil body embedded.
- Above the base body 1 and underneath a coil 3 is an armature-spring assembly 2 (see also FIG. 2), consisting of an anchor 21 and two contact springs 23 which are covered by an insulating material 27 are surrounded.
- torsion spring bars 25 To the torsion spring bars 25 close integrally formed connecting surfaces 26, which is perpendicular from the sheet plane the torsion spring bars 25 are bent.
- the torsion spring bars 25 and the connecting surfaces 26 form arms which grasp the center contact pins 12.
- the center contact pins 12 in turn also own the Connecting surfaces 26 of the torsion spring bars 25 abutting Connecting surfaces 13 (see Figure 2 and Figure 3).
- the Attachment of the connecting surfaces 26 to the connecting surfaces 13 of the center contact pins 12 is made by means of Welding.
- the base 4 made of insulating material are from a common circuit board manufactured connecting tracks 14 for fixed contacts 16 embedded.
- the fixed contacts 16 are on the connecting tracks 14 welded on.
- the contact connection elements 11 are connected by connecting tabs 5 (see also Figure 3) the common board for the connecting tracks 14th educated.
- the center contact pins 12 are by connecting tabs bent upwards formed while the connection elements 11 of the center contacts are bent down and through the bottom of the Protrude through base 4.
- the armature-spring assembly 2 two separate, parallel ones Contains contact springs 23, which are welded at their ends Wear switch contacts.
- the contact springs 23 are prefabricated from a common board and by a Isolierstoffabhülung 27 surrounded. Since the connecting surfaces 26 the torsion bars 25 and the connecting surfaces 13 of the center contact pins 12 in a plane perpendicular to the base plane rest against each other, is the armature-spring assembly 2 can be inserted into the base 4 from above. When reached the connection areas become a desired contact distance 26 to the connection surfaces 13 of the center contact pins 12 welded.
- the spring covering 27 has deformable fastening pins standing vertically upwards 28 on which the armature 21 is attached. By deforming these fastening pins 28, the armature 21 with the contact springs 23 and the spring sheath 27 to one Armature-spring assembly 2 firmly connected. Furthermore, the contact springs 23 slotted at their free ends, causing their Flexibility is increased.
- the formation of the vertical torsion spring bars 25 is illustrated by Figure 3.
- the leaf springs 23 have in side arms running parallel to their central region the free ends of which are each at right angles to the outside guided torsion spring bar 25 connects.
- the torsion spring bars 25 are bent upwards, which leads to the base level vertical alignment of their sheet plane is made.
- the contact springs 23 so far in its central area with an envelope 27 surround that only the free end portions of the contact springs 23 and the vertical torsion bars 25 protrude from the envelope 27 (see Figure 4).
- the torsion spring bars 25 on the center contact pins 12 quick and easy to assemble set the desired contact distance. Beyond that when assembling the desired anchor stroke in a simple way adjustable, that the coil 3 with the permanent magnet 33 can be pushed onto the base assembly until the desired one Anchor stroke is set. The coil 3 clamps with downward flange extensions of the coil body on the Socket 4.
