Electromagnetic relay, in particular miniature relay, with a housing block consisting of plastic material which has two side walls (3) running parallel to each other which have cut-out portions (26, 27) into which the magnet yoke (8) extends with its lateral edges without any play in such a way that the position of the magnetic system is fixed in the assembled state of the housing block, characterized in that the magnet yoke (18), viewed in the longitudinal direction (25), rests on each side at two points at a distance from each other on a supporting web (31, 32) in the cut-out portions (26, 27) and that in a first pair of cut-out portions (27) situated opposite to each other the supporting webs (32) which are there integral with said side walls (3) of the housing and the portions (34) opposite to these of the side walls (3) of the housing which limit the said cut-outs there are capable, through thermal and/or ultrasonic deformation, of being deformed and thereby cause a pivoting of the magnet yoke (18) around the supporting webs (31) in the second pair of cut-out portions in such a way that, by means of said change of position of said magnet yoke (18), the position of the armature (19) is adjustable in relation to the contact system (8) to be operated, the first pair of cut-out portions (27) being so disposed and the supporting webs (32) situated therein being of such a shape in the undeformed state that, even when the relay is not energized, the armature (19) is already in the operating position.

Description

Die vorliegende Erfindung bezieht sich auf eine elektromagnetisches ReLais, insbesondere Miniaturrelais, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an electromagnetic relay, in particular a miniature relay, according to the preamble of claim 1.

Ein derartiges Relais ist beispielsweise bekannt aus der DE-PS 22 13 146 und dem DE-GM 18 28 023. Bei letzterem sind am Magnetjoch seitlich abstehende Laschen vorgesehen, die beim Zusammenbau in je eine Aussparung einer Seitenwand eingreifen. Hierbei müssen die Kontaktsysteme nach dem Einbau des Magnetsystems entsprechend der Einbaulage des Magnetsystems justiert werden. Dies ist wegen der ELastizität der Kontaktbaustoffe relativ kompliziert und Langwierig.Such a relay is known, for example, from DE-PS 22 13 146 and DE-GM 18 28 023. In the latter, laterally projecting tabs are provided on the magnetic yoke, which each engage in a recess in a side wall during assembly. Here, the contact systems must be adjusted according to the installation position of the magnet system after installing the magnet system. This is relatively complicated and lengthy because of the elasticity of the contact building materials.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, ein ReLais der genannten Art so zu gestalten, daß die Justierung des Kontaktsystems relativ zum Magnetsystem bzw. des das Kontaktsystem betätigenden Ankers schnell und unkompliziert vorgenommen werden kann.The object of the present invention is to design a relay of the type mentioned so that the adjustment of the contact system relative to the magnet system or of the armature actuating the contact system can be carried out quickly and easily.

Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen MerkmaLe gelöst.This object is achieved by the features specified in the characterizing part of claim 1.

Weitere vorteilhafte EinzeLheiten der Erfindung sind in den Unteransprüchen angegeben und in der nachfolgenden Beschreibung eines AusführungsbeispieLes der Erfindung beschreiben. Dabei zeigen:

  • Fig. 1 eine Seitenansicht eines ReLais im Schnitt,
  • Fig. 2 einen verkleinerten Ausschnitt einer Ansicht von oben ohne GehäusedeckeL, teilweise geschnitten,
  • Fig. 3 einen vergrößerten Ausschnitt der einen Aussparung vor dem Justieren von der Seite und
  • Fig. 4 den Ausschnitt der Fig. 3 nach dem Justieren.
Further advantageous details of the invention are specified in the subclaims and are described in the following description of an exemplary embodiment of the invention. Show:
  • 1 is a side view of a relay in section,
  • 2 shows a reduced section of a view from above without the housing cover L, partly in section,
  • Fig. 3 shows an enlarged section of a recess before adjustment from the side and
  • Fig. 4 shows the detail of Fig. 3 after adjustment.

Mit 1 ist eine GehäuseschaLe aus thermoplastischem Kunststoff mit Stecköffnungen 2a und Steckzapfen 2b, einer Seitenwand 3, einem Bodenteil 4, einem Abdeckteil 5 und einem StirnteiL 6 bezeichnet. In die Seitenwand 3 sind Anschlußelemente 7 eingeformt, die zu dem oben herausstehenden Kontaktsystem 8, bestehend aus einem Kontaktanschluß 9, einer an diesem angeschweißten Kontaktfeder 10 und auf dieser angebrachten beweglichen KontakteLementen 11, 12, die mit festen KontakteLementen 13 bzw. 14 zusammenarbeiten, führen. Ein Anschlußelement 7 ist mit der nicht dargesteLLten SpuLe eines Magnetsystems 15 verbunden, das noch aus dem SpuLenkörper 16, einem SpuLenkern 17, einem mit dem Spulenkern 17 verbundenen Magnetjoch 18 und einem im Beispiel als KLappanker ausgebildeten beweglichen Anker 19 besteht. Letzterer wird über eine Andruckfeder 20 gegen die Endkante 21 des Magnetjoches 18 gedrückt und ist so schwenkbar geLagert. Die Andruckfeder 20 kann am SpuLenkörper angebracht oder an diesem angeformt sein, so daß er eine bauliche Einheit mit diesem bildet. Im Ruhezustand Liegt der eine SchenkeL 22 des Ankers 19 auf dem Magnetjoch 18 auf. Ein am Anker 19 angebrachter Kunststoffschaltnocken 23 kann das Ende 24 der Kontaktfeder 10 betätigen.1 with a housing shell made of thermoplastic with plug openings 2a and plug 2b, a side wall 3, a bottom part 4, a cover part 5 and a front part 6 is designated. In the side wall 3, connection elements 7 are formed, which lead to the contact system 8 protruding from the top, consisting of a contact connection 9, a contact spring 10 welded to it and movable contact elements 11, 12 attached to it, which cooperate with fixed contact elements 13 and 14, respectively . A connecting element 7 is connected to the coil (not shown) of a magnet system 15, which still consists of the coil body 16, a coil core 17, a magnetic yoke 18 connected to the coil core 17 and a movable armature 19 which is designed as a cap anchor. The latter is via a pressure spring 20th pressed against the end edge 21 of the magnetic yoke 18 and is thus pivotally mounted. The pressure spring 20 can be attached to the spool body or molded onto it, so that it forms a structural unit with it. In the idle state, one leg 22 of the armature 19 rests on the magnetic yoke 18. A plastic switching cam 23 attached to the armature 19 can actuate the end 24 of the contact spring 10.

Zwei solche GehäuseschaLen 1 bilden ein GehäuseteiL, in dem das Magnetsystem 15 Lagefixiert ist. Dieses Gehäuseteil kann auch aus mehreren TeiLen bestehen, beispielsweise wie in dem DE-GM 78 28 023 beschrieben und dargesteLLt. Erfindungsgemäß sind in der Seitenwand 3, in Richtung der Längsachse 25 gesehen, zwei Aussparungen 26 und 27 im Abstand hintereinander angeordnet. In diese greift ein seitlicher Ansatz 28 bzw, 29 des Magnetjoches 18 spielfrei ein. Die untere FLäche 30 der Aussparungen 26, 27 besitzt je einen AufLagesteg 31 bzw. 32, auf dem der Absatz 28 bzw. 29 aufliegt. Der AufLagepunkt der in Fig. 1 Links vorgesehenen Aussparung 26 dient als Schwenkpunkt 33 für das Magnetjoch 18.Two such housing shells 1 form a housing part in which the magnet system 15 is fixed in position. This housing part can also consist of several parts, for example as described and illustrated in DE-GM 78 28 023. According to the invention, two recesses 26 and 27 are arranged one behind the other in the side wall 3, as seen in the direction of the longitudinal axis 25. A lateral extension 28 or 29 of the magnetic yoke 18 engages in these without play. The lower surface 30 of the cutouts 26, 27 each has a support web 31 or 32 on which the shoulder 28 or 29 rests. The contact point of the recess 26 provided on the left in FIG. 1 serves as a pivot point 33 for the magnetic yoke 18.

Zur Justierung des Magnetsystems 15 gegenüber dem Kontaktsystem 8 kann das Magnetjeoch 18 in der Aussparung 27 dadurch abgesenkt werden, daß von oben mit einem heißen und/oder mit ULtraschaLL beaufschlagten StempeL auf das Abdeckteil 5 gedrückt wird, wobei der AufLagesteg 32 der Aussparung 27 erweicht und nach unten gestaucht wird. Dieser Vorgang erfolgt bei gleichzeitiger Messung des Kontaktabstandes bei am Ende 24 der Kontaktfeder 10 angreifenden SchaLtnocken 23, z.B. durch Messung des UmschaLtpunktes bei an dem Kontaktsystem 8 anliegender Spannung. Bei genauer Justierung, insbesondere beim oder nach dem UmschaLten vom einen in den anderen SchaLtzustand, wird der StempeLdruck beseitigt oder der StempeL ganz abgehoben, so daß das Magnetsystem 15 in der justierten Lage durch den erkalteten und erhärteten, deformierten Auflagesteg 32 und den an dieser SteLLe ebenfalls nach unten durchgezogenen, erkalteten und erhärteten TeiL 34 des Abdeckteils 5 fest gehaltert ist (Fig. 4).To adjust the magnet system 15 with respect to the contact system 8, the magnet yoke 18 in the recess 27 can be lowered by pressing the cover part 5 with a hot and / or ULtraschaLL from above, the support web 32 softening the recess 27 and is compressed downwards. This process takes place while measuring the contact distance at the end 24 of the contact spring 10 attacking switching cams 23, for example by measuring the changeover point with the voltage applied to the contact system 8. With precise adjustment, in particular during or after switching from one to the other switching state, the stamp pressure is removed or the stamp is lifted off completely, so that the magnet system 15 in the adjusted position by the cooled and hardened, deformed support web 32 and at this point also pulled down, cooled and hardened part 34 of the cover part 5 is firmly held (Fig. 4).

VorteiLhaft ist die Aussparung 27 mit dem zu verformenden AufLagesteg 32 im Bereich der als Schwenkachse dienenden Endkante 24 des Magnetjoches 18 vorgesehen und die Ansätze 29 sind ebenfalls am Ende des Magnetjoches 18 angeordnet.The recess 27 with the support web 32 to be deformed is advantageously provided in the region of the end edge 24 of the magnetic yoke 18 serving as a pivot axis, and the lugs 29 are also arranged at the end of the magnetic yoke 18.

An sich besteht erfindungsgemäß auch die MögLichkeit, ansteLLe zweier Aussparungen 26, 27 diese zu einer einzigen sich praktisch über die Länge des Magnetjoches 18 erstreckenden Aussparung zusammenzufassen. Hierbei könnte der gesamte seitliche Rand des Magnetjoches 18 in der Aussparung Liegen. Auch kann der AufLagesteg 31 durch eine entsprechende Formgebung des Magnetjoches 18 gebildet sein und hierdurch der Schwenkpunkt festgelegt werden.According to the invention, there is also the possibility of combining two cutouts 26, 27 into a single cutout which practically extends over the length of the magnetic yoke 18. Here, the entire side edge of the magnetic yoke 18 could lie in the recess. The support web 31 can also be formed by a corresponding shaping of the magnetic yoke 18 and the pivot point can thereby be fixed.

Es sei noch bemerkt, daß es notwendig ist, daß der AufLagesteg 33 und die Aussparung 27 derart angeordnet sind, daß im ursprünglichen, also unverformten Zustand, das Magnetjoch 18 und damit das gesamte Magnetsystem 15 zu hoch Liegt und das obere Kontaktpaar 11, 13 geschlossen ist. Ein Verformen des Auftagesteges 32 und des TeiLs 34 des AbdeckteiLs 5 öffnet das Kontaktpaar 11, 13 und das untere Kontaktpaar 12, 14 wird geschlossen. Dieses Kriterium dient vorzugsweise aLs Anzeige- und Einstellbedingung für die Justierung.It should also be noted that it is necessary for the support web 33 and the recess 27 to be arranged in such a way that the magnetic yoke 18 and thus the entire magnet system 15 lie too high in the original, ie undeformed state and the upper pair of contacts 11, 13 is closed. Deformation of the application web 32 and the part 34 of the cover part 5 opens the contact pair 11, 13 and the lower contact pair 12, 14 is closed. This criterion is preferably used as a display and setting condition for the adjustment.

Das ReLais kann durch einen DeckeL 35 verschlossen und ggfs. durch geeignete Maßnahmen, wie z.B. durch Vergießen, waschdicht gemacht sein.The ReLais can be closed with a blanket L 35 and, if necessary, with suitable measures, e.g. by shedding, be made wash-tight.
