Definitions

  • the invention relates to an electromagnetic relay with a coil with an axis running parallel to the connection plane of the relay, with at least one fixed mating contact element and in each flange a winding base being fastened in a first flange of the coil body, with a core inserted into the coil body in the axial direction, with an angular yoke, the first leg of which is coupled to a core end and the second leg of which extends parallel to the coil axis next to the winding, with an armature mounted in front of the free end of the second yoke leg, which forms a working air gap with the free core end, with one at the armature attached leaf spring, which causes the armature to be supported relative to the yoke with a return leg and interacts with at least one contact spring leg with the mating contact element, and with a connecting element which is electrically conductively connected to the leaf spring.
  • connection elements designed as flat plugs are essentially anchored in a base and subsequently connected to the associated electrical elements in the coil former.
  • These electrical connections for example between the winding bases in the bobbin flanges and the associated plug connections or between the contact spring and the associated connection element in the base, require additional operations, which are also not easily automated.
  • the assembly of the anchor is also included its bearing spring hardly accessible to automation.
  • the object of the invention is to construct a relay of the type mentioned at the outset in such a way that it can be produced with simpler parts and simpler operations, these operations being able to be carried out largely automatically.
  • this object is achieved in that a separately manufactured connector is attached to the free end of the second yoke leg, which has a support for the armature, a fastening section for the leaf spring and the integrally molded contact connecting element for the leaf spring, and that the winding bases directly by im each anchored coil connecting elements are formed.
  • the additional connector provided according to the invention is mechanically and electrically connected to the yoke. It is used not only for contacting the contact spring connected to the armature, but also for mounting and fastening the armature. With this connector, the assembly of the anchor is designed so that it can be carried out automatically. In contrast to conventional relays of a similar design, the armature does not need to be aligned with the fully assembled yoke and attached via its bearing spring. Rather, the armature and leaf spring can be aligned and fastened to the connecting piece in a pre-assembly, these operations being able to be carried out in a simple manner in machines by the separation of the yoke and the coil.
  • connection element for the contact spring is connected to the coil body via the yoke and the coil connection elements are anchored in the coil body flanges and serve directly as winding support points, and also a mating contact element can be anchored in a coil flange, such a relay can already be functional on the Coil formers are built.
  • a base which is inserted over the connection pins, merely has the function of a housing termination towards the connection side; So no subsequent solder connections between functional parts in the coil body and other functional parts in the base are required. Only when additional counter-contact elements are required, for a changeover contact or for a bridge contact, are these additional counter-contact elements anchored in a base. In this case, too, a subsequent solder connection after plugging the base is not necessary.
  • the connecting piece is expediently angled, at least one longitudinal section resting laterally on the second yoke leg and at least one transverse section resting on the free end face of the second yoke leg.
  • the connection piece is designed such that the second yoke leg engages with a stepped extension between the fork-shaped webs of the connection piece.
  • the longitudinal section of the connecting piece has two cranked connection tabs fastened flat on the second yoke leg and between them a fastening tab for the leaf spring.
  • the fastening tab for the leaf spring advantageously has a distance from the yoke leg and a predetermined bending point. In this way, the leaf spring connected to it, for example welded on, can be adjusted by bending the fastening tab.
  • the armature is angled and supported with its bearing leg on the extension of the second yoke leg.
  • the connecting element for the leaf spring can be integrally formed on the connecting piece via an intermediate strip which extends between the coil winding on the one hand and the armature or the second yoke leg on the other hand and is essentially connected to the connecting piece in the area of the upper yoke edge via a highly conductive cross section.
  • the relay shown in FIGS. 1 to 3 has as a supporting element a coil body 1 with two flanges 2 and 3 and a winding 4, a coil connecting element 5 and 6 being fastened in each of the coil flanges.
  • These coil connection elements 5 and 6 can be injected into the coil body; in the present exemplary embodiment, they are each anchored by means of a transverse web 5a or 6a in corresponding grooves in the respective coil flange or in an extension of the coil flange.
  • the coil former has an axial bore 1a for inserting a core (not shown) which is connected to a yoke 7 in the region of the coil flange 2.
  • This yoke 7 is of an angular configuration, the leg 7a being connected to the core mentioned, while the leg 7b extends next to the coil winding approximately parallel to its axis, but does not reach the full length of the coil.
  • a connector 8 is attached, which is substantially angled.
  • the longitudinal section 8a of the connector extends parallel to the yoke leg 7b, while the transverse section 8b of the connector with two fork-shaped webs 8c and 8d bears against the free end face of the yoke leg 7b, namely against the end faces 7c and 7d.
  • the webs 8c and 8d of the connecting piece in the form of a fork comprise an extension 7e which serves as a support for the mounting of an armature 9.
  • a contact connection element 8e is formed on the underside of the web 8d.
  • the armature 9 is of an angular shape and is supported with its leg 9a in the angle formed between the cross leg 8b of the connecting piece and the extension 7e of the yoke.
  • the second armature leg 9b is arranged on the front side in front of the coil flange 3 approximately perpendicular to the coil axis and forms a working air gap with the aforementioned, invisible core.
  • the armature is reset by a leaf spring 10 which is fastened to the connecting piece 8 with a restoring leg 10a, is fastened to the armature leg 9b with the armature holding leg 10b and forms a contact spring leg 10c with its free end which is extended beyond the free armature end. Due to the angular shape of the armature 9, its pivot point is shifted out of the contact plane, whereby an increased contact friction with the effect of self-cleaning is achieved.
  • the yoke 7 When installing the relay, the yoke 7 is first connected to the coil former 1, while an armature assembly, consisting of the armature 9, the connecting piece 8 and the leaf spring 10, is preassembled and then placed as a whole on the yoke or connected to the yoke leg 7b becomes.
  • the pre-assembled armature assembly is shown in Fig. 5. It can be seen that the leaf spring 10 is welded with its return leg 10a to a middle fastening leg 8f of the connector 8, which in turn lies between two connecting tabs 8g of the connector.
  • the two connecting tabs 8g are cranked toward the yoke leg 7b, so that the fastening tab 8f has a free distance from the yoke leg 7b and can thus be bent to adjust the leaf spring 10 or the armature 9.
  • a predetermined bending point 11 is also provided on the fastening tab 8f. 5 is placed on the yoke 7 connected to the coil former 1 and welded to the yoke leg 7b via the connecting tab 8g.
  • connection methods known to those skilled in the art such as soldering or riveting, can also be used for the welded connections mentioned.
  • the aforementioned adjustment by bending on the fastening tab 8f is carried out after the armature assembly has been mounted on the yoke or after the mounting of additional mating contact elements
  • the contact spring 10c is also connected to the associated connector 8e. If very high currents are to be switched for certain connection purposes, it may be expedient to connect the contact piece 12 of the contact spring 10c directly to the connection piece 8 via a flexible conductor element, for example a wire 13 additionally shown in FIG. 5.
  • connection element 18e is not directly molded onto the cross leg 18b, rather the connection piece there has an additional intermediate strip 18h, which essentially hangs on the cross leg 18b via the web 18i.
  • a further web 18k is also provided on the underside for reasons of stability, its cross section is dimensioned such that it represents a high resistance to the switching current flowing from the connecting element 18e to the leaf spring 10, so that the majority of the current flows through the web 18i flows.
  • a mounted relay with such a connector 18 is shown in Fig. 6.
  • the coil body flange 3 has an insertion shaft 14 for receiving a mating contact element 15, which cooperates with the contact piece 12 of the contact spring 10c.
  • a connection element which is not visible in the drawing, is formed.
  • the relay can receive various modifications to the contact arrangement, as shown in FIGS. 7 and 8, for example.
  • an extension 3a with an opening 3b for receiving a further mating contact element 17 is formed on the coil former flange 3.
  • this mating contact element 17 is fastened in a plug-in shaft 16a of the base 16 and, when the base is mounted, its extension 17a is inserted into the opening 3b.
  • the mating contact element 17, which is part of a changeover contact according to FIG. 7, is well positioned; this also ensures that the NC contact pair switches with little bounce.
  • Fig. 8 shows a further modification of the contact arrangement.
  • an additional mating contact element 19 is inserted in the slot 14, which cooperates with an additional leg 10d of the leaf spring 10.
  • the arrangement according to FIG. 8 is a bridge contact arrangement, so that the connection piece 8 does not have to perform any current-carrying function at all.
  • the contact distance between the contact element 19 and the spring leg 10d on the one hand and between the mating contact element 15 and the spring leg 10c can be set differently, as a result of which a lead contact can be created.
  • further modifications of the contact arrangement are also conceivable.
  • the relay can also be equipped with other components, such as resistors or diodes, which are connected in series or in parallel to the coil winding.
  • 2 shows an embodiment in which a parallel component 20 is arranged between the two coil flanges 2 and 3 and its connection ends are welded or soldered to the transverse webs 5a and 6a of the coil connection elements 5 and 6, respectively. Series connection of such a component is also possible.
  • the transverse web 6a is provided with a notch 6c, so that a retaining tab 6b is anchored separately in the coil flange 3 and is only connected to the connecting element 6 by a narrow web 6d.
  • a diode 21 is now to be connected in series in front of the coil winding, the web 6d is cut through, and the diode 21 is welded onto the rear of the connecting element 6 onto the now separated webs 6a and 6b, as shown in FIG. 9 .
  • a tab 6e is bent out for fastening and contacting the winding end 4a, next to which the winding end 4a is clamped and then soldered. The opposite winding end is fastened and contacted in a corresponding manner on a tab of the connection element 5.
