Abstract

A leakproof electromagnetic relay in which a pourable sealing compound is introduced into the interior of the lower housing of the relay. A recess is formed in at least one sidewall of the housing through which the sealing compound is poured. The compound distributes itself equally on the bottom of the housing and flows into the separating points or gaps of the housing by capillary action. A cover closes the recess after the compound has been poured in. The invention permits the relay to be sealed in its upright position and further processed.

Description

Die vorliegende Erfindung bezieht sich auf ein elektromagnetisches ReLais gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to an electromagnetic relay according to the preamble of claim 1.

Derartige ReLais werden zunehmend in sogenannter waschdichter Ausführung verlangt. Dies wird beispielsweise dadurch erreicht, daß der DeckeLrand unten über die Bodenfläche übersteht und dieser Raum bei umgedrehten ReLais ausgegossen wird. Zum besseren VerteiLen der Vergußmasse ist es dabei z.B. aus der DE-OS 28 51 329 und dem DE-GM 78 21 508 bekannt, die Bodenunterseite mit einem Netz von RiLLen zu versehen, die zu den TrennsteLLen zwischen GehäuseteiLen und GehäuseteiLen und KontaktanschLüssen führen. Durch Aufgeben einer vorbestimmten Menge Vergußmasse soll eine an allen Trennstellen, in die die Vergußmasse infolge KapiLLarwirkung eindringt, dichte Verbindung geschaffen werden.Such relays are increasingly required in a so-called wash-tight version. This is achieved, for example, by the fact that the ceiling edge protrudes below the floor surface and this space is poured out with reversed relays. For better distribution of the potting compound it is e.g. from DE-OS 28 51 329 and DE-GM 78 21 508 known to provide the bottom underside with a network of grooves which lead to the separating points between housing parts and housing parts and contact connections. By applying a predetermined amount of potting compound, a tight connection is to be created at all separation points into which the potting compound penetrates as a result of the capillary action.

Beim Vergießen von unten her kann es jedoch vorkommen, daß Vergußmasse durch eine zu große öffnung nach innen Läuft und das ReLais dadurch ggfs. unbrauchbar wird. Außerdem muß das ReLais in dieser SteLLung verharren, bis die Vergußmasse ausgehärtet ist.When casting from below, however, it can happen that the potting compound runs inwards through an opening that is too large and the ReLais can thereby become unusable. In addition, the relay must remain in this position until the casting compound has hardened.

Mit der vorliegenden Erfindung soLL die Aufgabe gelöst werden, ein ReLais in einfacher Weise waschdicht machen zu können, ohne daß schädliche Nebenwirkungen durch eine fatsche VerteiLung der Vergußmasse auftritt, und das ReLais nach dem Vergießen Leicht weiter handhabbar ist.The object of the present invention is to enable a relay to be made wash-proof in a simple manner without harmful side effects from a greasy distribution of the potting compound, and the relay to be easily handled after potting.

Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen MerkmaLe gelöst. Durch diese Maßnahmen kann das ReLais in seiner NormaLLage, also mit nach unten abstehenden AnschLüssen, vergossen werden. Hierdurch wird die Gefahr, daß Vergußmasse zum Kontaktsystem fließen kann, vermieden. Außerdem kann beim Vergießen zugleich eine Fixierung des Magnetsystems erfolgen. Weiterhin braucht der DeckeLrand nicht überzustehen, so daß eine geringere Bauhöhe erreichbar ist.This object is achieved by the features specified in the characterizing part of claim 1. These measures allow the ReLais to be cast in its normal position, i.e. with the connections protruding downwards. This avoids the risk that potting compound can flow to the contact system. In addition, the magnet system can also be fixed during casting. Furthermore, the ceiling edge does not have to protrude, so that a lower overall height can be achieved.

Das Miniaturrelais 1 besteht aus einem inneren bzw. unteren, im wesentlichen becherartigen, aus zwei Gehäuseschalen 2, 3 und einem SpuLenkörperfLansch 4 eines SpuLenkörpers 5 gebildeten unteren GehäuseteiLs 6 und einem becherartigen DeckeL 7, der das untere Gehäuseteil 6 etwa bis zum Boden 8 übergreift. Die beiden GehäuseschaLen 2, 3 besitzen im Querschnitt L-Form (siehe Fig. 2) und können zur BiLdung eines geschlossenen Raumes auch einen oberen Deckenabschnitt besitzen, so daß sie im Querschnitt die Form eines auf einem SchenkeL stehenden U biLden.The miniature relay 1 consists of an inner or lower, essentially cup-shaped, lower housing part 6 formed from two housing shells 2, 3 and a bobbin flange 4 of a bobbin 5 and a cup-like cover L 7 which overlaps the lower housing part 6 approximately to the bottom 8. The two housing shells 2, 3 have an L-shape in cross section (see FIG. 2) and can also have an upper ceiling section to form a closed space, so that in cross section they have the shape of a U standing on a leg.

In den die Seitenwände 9, 10 des unteren, aus Kunststoff bestehenden GehäuseteiLs 6 bildenden Wänden der Gehäuseteile 2, 3 sind die Metallteile 11 der Kontaktsysteme 12 und der AnschLüsse 13 in an sich bekannter Weise eingeformt.The metal parts 11 of the contact systems 12 and the connections 13 are molded in a manner known per se into the walls of the housing parts 2, 3 forming the side walls 9, 10 of the lower housing part 6 made of plastic.

Das untere Gehäuseteil 6 kann auch aus einem einzigen KunststoffteiL bestehen oder es kann aus mehreren TeiLen zusammengesetzt sein, beispielsweise aus zwei Seiten-Mänden 9, 10 und einem mittleren U-förmigen TeiL.The lower housing part 6 can also consist of a single plastic part or it can be composed of several parts, for example of two side walls 9, 10 and a central U-shaped part.

Die einzelnen GehäuseteiLe können durch den DeckeL 7 zusammengehalten sein oder vorher noch durch geeignete Maßnahmen verbunden sein, beispielsweise durch Stecken, KLeben, Schweißen mittels ULtraschaLL etc.The individual housing parts can be held together by the cover 7 or previously connected by suitable measures, for example by plugging, gluing, welding by means of ultrasonic etc.

Im unteren Gehäuseteil 6 ist das aus dem SpuLenkörper 5, einer Wicklung 14, einem Magnetkern 15, einem mit diesem magnetisch und mechanisch fest verbundenen Magnetjoch 16 und einem KLappanker 17 bestehende Magnetsystem des ReLais 1 untergebracht. Zweckmäßig sind am Spulenkärper 5 Stand Laschen 18 angeformt, mit denen er auf der inneren OberfLäche 19 des Bodens 8 steht.In the lower housing part 6, this consists of the bobbin 5, a winding 14, a magnetic core 15, one with the latter magnetically and mechanically firmly connected magnetic yoke 16 and a cap anchor 17 existing magnetic system of the relay 1 housed. Appropriately, tabs 18 are formed on the bobbin 5 stand, with which it stands on the inner surface 19 of the bottom 8.

Um ein waschdichtes ReLais 1 zu erhalten, müssen die zwischen den einzelnen BauteiLen vorhandenen TrennsteLLen bzw. Stoßfugen 20 dicht verschlossen werden. Dies erfolgt erfindungsgemäß von innen dadurch, daß in wenigstens einer wand, insbesondere den Seitenwänden 9, 10 des unteren GehäuseteiLs 6, zumindest eine Aussparung 21 vorgesehen ist, durch die von außen Vergußmasse 22 eingefüllt werden kann. Letztere verläuft innen am Boden 8 des unteren GehäuseteiLs 6 und Läuft infolge KapiLLarwirkung in die TrennsteLLen 20 der relativ dicht aneinanderliegenden BauteiLe 2, 3.In order to obtain a wash-tight relay 1, the separating points or butt joints 20 between the individual components must be tightly sealed. According to the invention, this takes place from the inside in that at least one recess 21 is provided in at least one wall, in particular the side walls 9, 10 of the lower housing part 6, through which potting compound 22 can be filled in from the outside. The latter runs on the inside at the bottom 8 of the lower housing part 6 and, due to the capillary effect, runs into the separating points 20 of the relatively closely adjacent components 2, 3.

In wenigstens einer Seitenwand 2, 3 und/oder dem SpuLenkörperflansch 4 ist zumindest eine bis zur Oberfläche 19 des Bodens 8 hinabreichende öffnung 23 vorgesehen, durch die hindurch Vergußmasse22 von innen nach außen fLießen kann. Hierdurch kann nach EinfüLLen der Vergußmasse 22 durch die Aussparung 21 hindurch und anschließendes Aufschieben des DeckeLs 7, dessen Wände 24 die Aussparungen 21 im aufgeschobenen Zustand überdecken, die Vergußmasse 22 infolge KapiLLarwirkung durch die öffnungen 23 hindurch in die TrennsteLLen 20 zwischen den DeckeLwänden 24 und dem unteren GehäuseteiL 6 Laufen.In at least one side wall 2, 3 and / or the bobbin flange 4 there is at least one opening 23 which extends down to the surface 19 of the base 8 and through which casting compound 22 can flow from the inside to the outside. As a result, after filling the potting compound 22 through the recess 21 and then pushing on the cover 7, the walls 24 of which cover the recesses 21 in the pushed-on state, the potting compound 22 as a result of the capillary effect through the openings 23 into the separating points 20 between the cover walls 24 and the lower housing part 6 running.

Durch die Kapillarwirkung an den TrennsteLLen 20 kann keine Vergußmasse 22 nach unten herauslaufen oder heraustropfen.Due to the capillary action at the separating points 20, no potting compound 22 can run out or drip out.

Die öffnungen 23 können sich aLs SchLitz 25 von der Unterkante der Aussparung 21 aus nach unten bis zur Oberfläche 19 des Bodens 8 erstrecken oder die öffnungen 23 können durch kleine Bohrungen 26 gebildet sein, die oberhalb des Bodens 8 angebracht sind, jedoch bis zur Oberfläche 19 hinabreichen. Die öffnungen 23 können am Umfang so verteilt werden, daß ein gleichmäßiges VerLaufen zu aLLen TrennsteLLen 20 hin in einer bestimmten Zeiteinheit erfolgen kann.The openings 23 can extend as a slot 25 from the lower edge of the recess 21 down to the surface 19 of the base 8 or the openings 23 can be formed by small bores 26 which are provided above the base 8 but up to the surface 19 reach down. The openings 23 can be distributed around the circumference in such a way that they can run evenly to all the separating points 20 in a certain time unit.

ALs Vergußmasse 22 wird vorteilhaft eine solche gewählt, die bei Temperaturerhöhung eine niedrigere Viskosität aufweist. Hierdurch kann nach dem Eingießen derselben und dem Aufstecken des DeckeLs 7 durch Erwärmung eine schneLLere und gleichmäßigere VerteiLung und ein gutes - VerLaufen in den TrennLinien 20 oder TrennfLächen erreicht werden.As the potting compound 22, it is advantageous to choose one which has a lower viscosity when the temperature rises. As a result, after pouring the same and fitting the cover 7 by heating, a faster and more uniform distribution and a good flow in the separating lines 20 or separating surfaces can be achieved.

VorteiLhaft kann das Vergießen von innen dazu benutzt werden, um innere Teile, z.B. den Spulenflansch 26, am Boden 8 zu verankern. Beispielsweise können am SpuLenkörper 5, insbesondere am FLansch 27, die StandLaschen 18 angeformt sein, die auf der Oberfläche 19 stehen und die mit in die Vergußmasse 22 eingebettet sind. Hierdurch wird eine erschütterungsfreie HaLtung des Magnetsystems gewährleistet.Advantageously, the potting from the inside can be used to remove internal parts, e.g. to anchor the coil flange 26 to the floor 8. For example, the stand tabs 18, which stand on the surface 19 and which are also embedded in the casting compound 22, can be formed on the bobbin 5, in particular on the flange 27. This guarantees vibration-free retention of the magnet system.

Bei Anordnung der Aussparungen 21 in einer Seitenwand 9 und/oder 10 sind diese derart angeordnet und/oder die MetaLLteiLe 11 sind derart stufenförmig oder schräg verlaufend vorgesehen, daß sie nicht durch eine Aussparung 21 verLaufen.When the cutouts 21 are arranged in a side wall 9 and / or 10, they are arranged in such a way and / or the metal parts 11 are provided in a stepped or oblique manner such that they do not run through a cutout 21.
