Description

Beschreibungdescription
Elektromagnetisches RelaisElectromagnetic relay
Die Erfindung betrifft ein elektromagnetisches Relais mit ei¬ ner zwischen dem Magnetsystem einerseits und der Kontaktan¬ ordnung andererseits angeordneten Isolierwand, welche eine Mehrzahl von Isolierschichten aufweist. Außerdem betrifft die Erfindung ein Verfahren zur Herstellung eines derartigen Re- lais.The invention relates to an electromagnetic relay with an insulating wall arranged between the magnet system on the one hand and the contact arrangement on the other hand, which has a plurality of insulating layers. The invention also relates to a method for producing such a relay.
Zur sicheren elektrischen Trennung zwischen den an Netzspan¬ nung liegenden Teilen eines Relais einerseits und anderen, berührbaren Teilen bzw. den Metallteilen des Magnetkreises sind bestimmte Mindestabstände durch Isolierung einzuhalten. Dies ist in entsprechenden Normen und Vorschriften geregelt. Beispielsweise können die Isolierabstände durch einfache Iso¬ lierung mittels einer einstückigen Isolierwand realisiert werden, wobei diese dann eine bestimmte Mindestdicke nicht unterschreiten darf. Eine andere Möglichkeit besteht darin, die Isolierwand aus beispielsweise mindestens drei Einzel¬ schichten zu bilden, wobei dann die Wandstärke dieser Einzel¬ schichten nicht mehr vorgeschrieben ist. Es muß dann für die einzelnen Schichten jeweils die Spannungsfestigkeit getrennt nachgewiesen werden. Bei der zunehmenden Forderung nach Mi¬ niaturisierung von elektrischen Bauelementen allgemein und Relais im besonderen wird deshalb versucht, die Isolations¬ forderungen durch die Bildung mehrschichtiger Isolierwände mit möglichst dünnen Einzelschichten zu erfüllen.For safe electrical separation between the parts of a relay connected to the mains voltage and other touchable parts or the metal parts of the magnetic circuit, certain minimum clearances must be maintained by insulation. This is regulated in the relevant standards and regulations. For example, the insulation distances can be realized by simple insulation using a one-piece insulation wall, which then must not be less than a certain minimum thickness. Another possibility is to form the insulating wall from, for example, at least three individual layers, the wall thickness of these individual layers then no longer being prescribed. The dielectric strength must then be verified separately for the individual layers. With the increasing demand for miniaturization of electrical components in general and relays in particular, attempts are therefore being made to meet the insulation requirements by forming multilayer insulation walls with the thinnest possible individual layers.
In dem Gebrauchsmuster DE 9210790 UI wird beispielsweise vor¬ geschlagen, durch zwei ineinander geschachtelte Kappenteile eine Basisisolierung und eine Zusatzisolierung mit entspre¬ chenden Spannungsfestigkeitswerten zu bilden. Die Herstellung und Faltung dieser Kappenteile erfordert jedoch aufwendigeIn the utility model DE 9210790 UI it is proposed, for example, to form basic insulation and additional insulation with corresponding dielectric strength values by means of two nested cap parts. The production and folding of these cap parts, however, requires complex
Arbeitsgänge und bringt auch noch keine optimale Raumausnut¬ zung. Ein Relais der eingangs genannten Art ist auch bereits in dem Gebrauchsmuster DE 8914910 UI beschrieben. Dort ist eine aus drei Isolierschichten bestehende Isolierwand unter anderem dadurch realisiert, daß an einem ersten Isolierteil zweiOperations and does not yet bring optimal space utilization. A relay of the type mentioned is also already described in the utility model DE 8914910 UI. There, an insulating wall consisting of three insulating layers is realized, inter alia, by two on a first insulating part
Wände mit einer zwischenliegenden Tasche geformt werden, wo¬ bei die dritte Wand in Form einer Folie in die Tasche ge¬ steckt werden kann. In diesem Fall muß also die Folie als zu¬ sätzliches Teil hergestellt, geschnitten und eingesteckt wer- den. Um ein problemloses Einstecken dieser Folie zu gewähr¬ leisten, kann die Spaltbreite in der Tasche nicht beliebig klein gewählt werden.Walls are formed with an intermediate pocket, whereby the third wall can be inserted into the pocket in the form of a film. In this case, the film must be manufactured, cut and inserted as an additional part. In order to ensure problem-free insertion of this film, the gap width in the pocket cannot be chosen to be as small as desired.
Aufgabe der vorliegenden Erfindung ist es deshalb, ein Relais der eingangs genannten Art so zu gestalten, daß eine Isolier¬ wand mit mehreren Schichten möglichst dünn gestaltet und auf möglichst einfache Weise hergestellt werden kann.The object of the present invention is therefore to design a relay of the type mentioned at the outset in such a way that an insulating wall with a plurality of layers is made as thin as possible and can be produced in the simplest possible manner.
Erfindungsgemäß wird dies dadurch erreicht, daß die Isolier- wand aus einer Wandbasis mit mindestens einem, sich in einer für eine Isolierschicht vorgesehenen Ebene erstreckenden Iso¬ lierspalt gebildet ist und daß in dem Isolierspalt die Iso¬ lierschicht durch flüssig eingefülltes und nachträglich aus¬ gehärtetes Isoliermaterial gebildet ist.According to the invention, this is achieved in that the insulating wall is formed from a wall base with at least one insulating gap extending in a plane provided for an insulating layer, and in the insulating gap in the insulating gap by means of insulating material which is filled with liquid and subsequently hardened is formed.
Durch die erfindungsgemäße Gestaltung ist also nur ein einzi¬ ges Formteil erforderlich, welches beispielsweise zwei Iso¬ lierschichten mit dem erwähnten Spalt bildet, wobei diese Wandbasis auch einstückiger Teil eines Relaisgrundkörpers sein kann, der etwa das MagnetSystem trägt und/oder die Kon¬ taktelemente aufnimmt. Eine oder auch mehrere zusätzliche Isolierschichten werden durch einfaches Einfüllen des flüssi¬ gen Isolierstoffs in den Spalt bzw. in die Spalte gebildet. Dies erfordert je nach den Umständen nicht einmal einen zu- sätzlichen Fertigungsschritt, da meist ohnehin flüssige Ver¬ gußmasse zum Abdichten des Relais eingefüllt werden muß. Eine zusätzliche Isolierschicht kann beispielsweise auch durch Einfüllen des flüssigen Isolierstoffs in einen Grund¬ körperspalt erfolgen, der ansonsten zur Aufnahme eines Kon¬ taktträgers vorgesehen ist. Dabei muß nur sichergestellt wer- den, daß der Kontaktträger in dem Spalt an der von der gefor¬ derten Isolierwand abgelegenen Seite positioniert wird, so daß der Kontaktträger die Bildung der mehrschichtigen Iso¬ lierwand nicht beeinträchtigt. Die Breite des Isolierspaltes kann so gering gewählt werden, wie es das Formwerkzeug, d. h. die geringstmögliche Messerbreite eines Formeinsatzes, zu¬ läßt. Der flüssige Isolierstoff kann je nach den Umständen und nach seiner Viskosität durch eigene Schwerkraft in den Isolierspalt fließen oder unter Druck eingespritzt werden. Dabei hilft auch die Kapillarwirkung des Isolierspaltes, den flüssigen Isolierstoff bis in das innere Ende des Spaltes zu befördern. Zweckmäßigerweise wird im Bereich des inneren En¬ des eine Entlüftungsöffnung in der Wandbasis vorgesehen.Due to the design according to the invention, therefore, only a single molded part is required, which, for example, forms two insulating layers with the gap mentioned, wherein this wall base can also be an integral part of a relay base body which, for example, carries the magnet system and / or accommodates the contact elements . One or more additional insulating layers are formed by simply pouring the liquid insulating material into the gap or into the gap. Depending on the circumstances, this does not even require an additional manufacturing step, since mostly liquid casting compound has to be filled in anyway to seal the relay. An additional insulating layer can also be provided, for example, by filling the liquid insulating material into a basic body gap, which is otherwise provided for receiving a contact carrier. It is only necessary to ensure that the contact carrier is positioned in the gap on the side remote from the required insulating wall, so that the contact carrier does not impair the formation of the multilayer insulating wall. The width of the insulating gap can be chosen to be as small as the mold, ie the smallest possible knife width of a mold insert, allows. Depending on the circumstances and its viscosity, the liquid insulating material can flow into the insulating gap by gravity or can be injected under pressure. The capillary action of the insulating gap also helps to convey the liquid insulating material into the inner end of the gap. A vent is expediently provided in the wall base in the area of the inner end.
Ein erfindungsgemäßes Verfahren zur Herstellung eines solchen Relais besteht darin, daß ein Grundkörper mit einem Boden¬ teil, einer von dem Bodenteil nach oben abstehenden Isolier¬ wand mit Steckkanälen für Kontaktträger und mindestens einem Isolierspalt im Bereich der Isolierwand aus Isolierstoff ge¬ formt wird, daß an dem Grundkörper das MagnetSystem und die Kontaktanordnung befestigt werden und daß schließlich der Isolierspalt mit einem flüssigen Isolierstoff ausgespritzt und dieser Isolierstoff danach ausgehärtet wird.A method according to the invention for producing such a relay consists in that a base body with a base part, an insulating wall protruding upward from the base part with plug-in channels for contact carriers and at least one insulating gap in the region of the insulating wall is formed from insulating material, that be attached to the base body, the magnet system and the contact arrangement and that finally the insulating gap is sprayed with a liquid insulating material and this insulating material is then cured.
Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert. Es zeigtThe invention is explained in more detail below using an exemplary embodiment. It shows
Figur 1 ein erfindungsgemäß gestaltetes Relais ohne Kappe und1 shows a relay designed according to the invention without a cap and
Figur 2 eine abgebrochene Seitenansicht des Relais von Figur 1, teilweise geschnitten gezeichnet. Das in den Figuren 1 und 2 gezeigte Relais besitzt einen Grundkörper 1 aus Isolierstoff, auf dem ein Magnetsystem mit einer Spule 2, einem abgewinkelten Joch 3 und einem Anker 4 angeordnet ist. Der Anker 4 betätigt über einen Schieber 5 eine Kontaktfeder 6, die über einen Federträger 7 in einem Schlitz 8 des Grundkörpers 1 verankert ist. Ein Öffner-Kon¬ taktträger 9 ist in einem Schlitz 10 des Grundkörpers veran¬ kert, entsprechend ein Schließer-Kontaktträger 11 in einem Schlitz 12 des Grundkörpers 1. Eine Isolierstoff-Kappe 13 bildet zusammen mit dem Grundkörper 1 ein geschlossenes Ge¬ häuse.Figure 2 is a broken side view of the relay of Figure 1, drawn partially in section. The relay shown in FIGS. 1 and 2 has a base body 1 made of insulating material, on which a magnet system with a coil 2, an angled yoke 3 and an armature 4 is arranged. The armature 4 actuates a contact spring 6 via a slide 5, which is anchored via a spring support 7 in a slot 8 of the base body 1. An opener contact carrier 9 is anchored in a slot 10 of the base body, correspondingly a closer contact carrier 11 in a slot 12 of the base body 1. An insulating material cap 13 forms a closed housing together with the base body 1.
An dem Grundkörper 1 ist weiterhin eine Trennwand 14 ange¬ formt, welche zusammen mit einer nach unten ragenden Kappen- wand 15 eine Zweischichtisolierung zwischen dem Joch und dem kontaktgebenden Ende des Schließer-Kontaktträgers 9 bildet. In diesem Bereich ist zudem der Abstand ohnehin relativ groß, so daß die erforderlichen Isolierstrecken eingehalten werden.A partition 14 is also formed on the base body 1, which, together with a cap wall 15 projecting downward, forms a two-layer insulation between the yoke and the contacting end of the make contact carrier 9. In this area, the distance is also relatively large anyway, so that the required insulating distances are maintained.
Kritisch ist hingegen der Abstand zwischen dem Knickbereich 16 des Joches 3 und dem Schließer-Kontaktträger 9. Dieser Schließer-Kontaktträger 9 ist gegenüber dem kontaktgebenden Ende schräg nach rechts gezogen, um einen gewünschten großen Abstand zwischen den Anschlußstiften der Kontaktelemente zu erhalten. Um nun die Isolationsforderung mit drei Isolier¬ schichten zu erfüllen, ist im Grundkörper 1 in dem erwähnten kritischen Bereich ein Isolierspalt 17 ausgespart, der nach¬ träglich mit flüssigem Isoliermaterial gefüllt wird. Nach dem Aushärten bildet dieses Isoliermaterial in dem Spalt 17 eine zusätzliche Isolierschicht zwischen den vom Grundkörper ge¬ bildeten Wandschichten 18 und 19. Damit beim Einspritzen oder Einfüllen des zusätzlichen flüssigen Isoliermaterials kein Luftstau im Inneren des Isolierspaltes 17 entsteht, ist zum Inneren des Grundkörpers eine Entlüftungsöffnung 20 vorgese- hen. Durch diese kann überschüssiges Isoliermaterial in den Hohlraum 21 gelangen und dort aushärten. Zusätzlich könnte auch in dem Befestigungsschlitz 10 des Schließer-Kontaktträgers 9 Isoliermaterial eingefüllt werden, um eine weitere Isolierschicht zu bilden. In diesem Fall muß jedoch darauf geachtet werden, daß der Kontaktträger 9 inner- halb des Schlitzes 10 an der vom Joch entfernten Wand posi¬ tioniert wird, damit das eingefüllte Isoliermaterial tatsäch¬ lich als wirksame Isolierschicht zwischen dem Kontaktträger 9 und dem Joch 3 liegt.However, the distance between the kink area 16 of the yoke 3 and the make contact carrier 9 is critical. This make contact carrier 9 is drawn obliquely to the right relative to the contacting end in order to obtain a desired large distance between the connecting pins of the contact elements. In order to meet the insulation requirement with three insulating layers, an insulating gap 17 is left in the basic body 1 in the critical area mentioned, which is subsequently filled with liquid insulating material. After hardening, this insulating material forms an additional insulating layer in the gap 17 between the wall layers 18 and 19 formed by the base body. In order that no air build-up occurs in the interior of the insulating gap 17 when the additional liquid insulating material is injected or filled in, there is a vent opening to the interior of the base body 20 provided. Excess insulation material can pass through this into the cavity 21 and harden there. In addition, insulating material could also be filled into the fastening slot 10 of the make contact carrier 9 in order to form a further insulating layer. In this case, however, care must be taken that the contact carrier 9 is positioned within the slot 10 on the wall remote from the yoke so that the filled insulating material actually lies as an effective insulating layer between the contact carrier 9 and the yoke 3.
Das zusätzlich eingefüllte Isoliermaterial zur Bildung der zusätzlichen Isolierschicht kann auch gleichzeitig mit einem Verguß der Sockelseite zur Abdichtung der Kontaktträger¬ schlitze 8, 10 und 12 eingebracht werden. The additionally filled insulating material for forming the additional insulating layer can also be introduced simultaneously with a potting of the base side to seal the contact carrier slots 8, 10 and 12.
