Abstract

1. 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 betrifft ein elektromagnetisches Relais, insbesondere Miniaturrelais, gemäss dem ersten Teil des Anspruchs 1.The present invention relates to an electromagnetic relay, in particular a miniature relay, according to the first part of claim 1.

Ein derartiges Relais ist beispielsweise bekannt aus der DE-C-2 213 146 und der DE-U-7 828 023. Bei letzterem besteht das Gehäuse aus mehreren miteinander verklebten oder verschweissten Teilen aus thermoplastischem Kunststoff, wobei in den zwei zueinander parallelen Seitenwänden Aussparungen vorgesehen sind, in die je ein überstehendes Randstück des Magnetjoches derart eingreift, dass in zusammengesetztem, z.B. verschweisstem Zustand das Magnetjoch lagefixiert ist. Thermoplastische Erzeugnisse können wegen des verfahrensbedingten Schrumpfens nur innerhalb relativ weiter Toleranzgrenzen hergestellt werden. Nach dem Zusammenbau des Relais müssen daher die Kontaktsysteme, auch wegen der möglichen unterschiedlichen Zusammensetzung und beispielsweise Verschweissung der Gehäuseteile, entsprechend der möglichen unterschiedlichen Einbaulage des Magnetsystems justiert werden. Dies ist wegen der Elastizität der Kontaktwerkstoffe relativ kompliziert und langwierig.Such a relay is known, for example, from DE-C-2 213 146 and DE-U-7 828 023. In the latter case, the housing consists of several parts made of thermoplastic plastic which are glued or welded to one another, with recesses being provided in the two mutually parallel side walls are in which each protruding edge piece of the magnetic yoke engages in such a way that in a composite, for example welded condition the magnetic yoke is fixed in position. Because of the process-related shrinkage, thermoplastic products can only be manufactured within relatively wide tolerance limits. After the relay has been assembled, the contact systems must also be adjusted according to the possible different installation position of the magnet system, also because of the possible different composition and, for example, welding of the housing parts. Because of the elasticity of the contact materials, this is relatively complicated and lengthy.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, ein Relais der eingangs genannten Art so zu gestalten, dass die Justierung des Kontaktsystems durch Veränderung der Lage des Betätigungsgliedes des Magnetsystems relativ zum Kontaktsystem schnell und unkompliziert mit der erforderlichen Genauigkeit vorgenommen werden kann.With the present invention, the object is to be designed to design a relay of the type mentioned in such a way that the adjustment of the contact system can be carried out quickly and easily with the required accuracy by changing the position of the actuator of the magnet system relative to the contact system.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Durch die thermoplastische Verformung der die Lage des Magnetsystems fixierenden Seitenwandteile kann der Abstand zwischen Kontaktsystem und betätigendem Teil des Magnetsystems auch noch nach vollständigem Zusammenbau des Relais jederzeit genau eingestellt werden.This object is achieved by the features specified in the characterizing part of claim 1. Due to the thermoplastic deformation of the side wall parts fixing the position of the magnet system, the distance between the contact system and the actuating part of the magnet system can be precisely adjusted at any time even after the relay has been completely assembled.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Nachfolgend wird ein Ausführungsbeispiel der Erfindung beschrieben. 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.
Advantageous developments of the invention are specified in the subclaims. An exemplary embodiment of the invention is described below. Show:
  • 1 is a side view of a relay in section,
  • 2 shows a reduced section of a view from above without a housing cover, partially cut,
  • 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 mit Anschlussstelle 9 führen. An diese ist eine Kontaktfeder 10 angeschweisst, an der bewegliche Kontaktelemente 11, 12 angebracht sind, die mit festen Kontaktelementen 13 bzw. 14 zusammenarbeiten. 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 denotes a housing shell made of thermoplastic material with plug-in openings 2a and plug-in pins 2b, a side wall 3, a bottom part 4, a cover part 5 and a front part 6. Connection elements 7 are formed in the side wall 3, which lead to the contact system 8 with connection point 9 protruding above. A contact spring 10 is welded onto this, to which movable contact elements 11, 12 are attached, 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 former 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 hinged armature in the example. The latter is pressed against the end edge 21 of the magnetic yoke 18 by means of a pressure spring 20 and is thus pivotably mounted. The pressure spring 20 can be attached to the bobbin 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 mehr als zwei Teilen bestehen, beispielsweise wie in der DE-U-7 828 023 beschrieben und dargestellt. In der Seitenwand 3 sind, 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 eine Auswölbung 31 bzw. 32, auf denen der Ansatz 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 more than two parts, for example as described and shown in DE-U-7 828 023. In the side wall 3, as seen in the direction of the longitudinal axis 25, two recesses 26 and 27 are arranged one behind the other at a distance. A lateral extension 28 or 29 of the magnetic yoke 18 engages in these without play. The lower surface 30 of the recesses 26, 27 each has a bulge 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 Magnetjoch 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, wodurch die Auswölbung 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 die erkaltete und erhärtete, deformierte Auswölbung 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 can be lowered in the recess 27 by pressing on the cover part 5 with a hot and / or ultrasound-loaded stamp, whereby the bulge 32 of the recess 27 softens and is pushed down. This process takes place with simultaneous measurement of the contact distance with switching cams 23 acting on the end 24 of the contact spring 10, e.g. by measuring the switchover 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 due to the cooled and hardened, deformed bulge 32 and the at this point is also firmly held down, cooled and hardened part 34 of the cover part 5 (Fig. 4).

Vorteilhaft ist die Aussparung 27 mit der zu verformenden Auswölbung 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 bulge 32 to be deformed is advantageously provided in the region of the end edge 24 of the magnetic yoke 18 serving as the pivot axis, and the lugs 29 are also arranged at the end of the magnetic yoke 18.

Anstelle zweier Aussparungen 26, 27 kann auch eine einzige, sich praktisch über die Länge des Magnetjoches 18 erstreckende Aussparung vorgesehen werden. Hierbei könnte der gesamte seitliche Rand des Magnetjoches 18 in der Aussparung liegen. Auch kann die Auswölbung 31 durch eine entsprechende Formgebung des Magnetjoches 18 gebildet sein und hierdurch der Schwenkpunkt festgelegt werden.Instead of two cutouts 26, 27, a single cutout extending practically over the length of the magnetic yoke 18 can also be provided. Here, the entire lateral edge of the magnetic yoke 18 could lie in the recess. The bulge 31 can also be formed by a corresponding shaping of the magnetic yoke 18 and the pivot point can thereby be determined.

Es ist notwendig, die Auswölbung 32 und die Aussparung 27 derart anzuordnen, 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 der Auswölbung 32 und des Teils 34 des Abdeckteils 5 öffnet das Kontaktpaar 11, 13 und das untere Kontaktpaar 12, 14 wird geschlossen. Dieses Schliessen dient vorzugsweise als Einstellkriterium für die Justierung.It is necessary to bulge 32 and out arrange savings 27 such that in the original, ie undeformed state, the magnet yoke 18 and thus the entire magnet system 15 is too high and the upper contact pair 11, 13 is closed. Deformation of the bulge 32 and of the part 34 of the cover part 5 opens the contact pair 11, 13 and the lower contact pair 12, 14 is closed. This closing preferably serves as a setting criterion for the adjustment.

Das Relais kann durch einen Deckel 35 verschlossen und beispielsweise durch Vergiessen, waschdicht gemacht sein.The relay can be closed by a cover 35 and made wash-tight, for example by casting.
