Description

Die Erfindung betrifft die Anordnung eines Relais auf einem Stecksockel, wobei das Relais ein Gehäuse aus formstabilem Material besitzt, aus dessen Bodenseite Steckerstifte herausragen, und wobei der Stecksockel ein Gehäuse aus ebenfalls formstabilem Material mit zu seiner Oberseite offenen, die Steckerstifte des Relais aufnehmenden Stecköffnungen besitzt. Unter Relais wird in diesem Zusammenhang auch ein sogenanntes Relaismodul verstanden, bei dem in dem Gehäuse zusätzlich zu dem eigentlichen Relaissystem weitere Schaltungselemente, wie Widerstände und Dioden mit den zugehörigen Leiterbahnen, angeordnet sind.The invention relates to the arrangement of a relay on a Plug-in base, the relay being a housing made of dimensionally stable Has material with pins sticking out of the bottom, and wherein the socket is a housing also dimensionally stable material with the top open Has plug pins of the relay receiving plug openings. In this context, a so-called relay is also used Relay module understood, in addition to in the housing the actual relay system further circuit elements, such as Resistors and diodes with the associated conductor tracks are.

Zur Abdichtung von Relaisgehäusen sind viele Möglichkeiten bereits beschrieben worden, beispielsweise das Vergießen von Gehäusespalten mit flüssiger und nachträglich aushärtbarer Vergußmasse. Bekannt ist es auch (DE 43 37 505 C1), Wandbereiche zwischen Sockel oder Bodenplatte einerseits und Kappe andererseits im Zweikomponenten-Spritzverfahren mit einer Elastomerschicht zu überziehen und so beim Aufeinanderpressen der Gehäuseteile die gewünschte Abdichtung zu erreichen.There are many options for sealing relay housings have already been described, for example the shedding of Housing gaps with liquid and subsequently curable Sealing compound. It is also known (DE 43 37 505 C1), wall areas between base or base plate on the one hand and cap on the other hand, in a two-component spraying process with a Cover the elastomer layer and so when pressed together the housing parts to achieve the desired seal.

Wird jedoch ein Relais in einen Stecksockel eingesetzt, wie dies beispielsweise in Kraftfahrzeugen üblich ist, so bleibt die Steckverbindung zwischen Relais und Stecksockel ungeschützt, auch wenn das Relais selbst abgedichtet ist. Da solche Stecksockel, namentlich im Motorraum von Kraftfahrzeugen, häufig einer starken Verschmutzung oder Feuchtigkeit ausgesetzt sind, ist es bisher üblich, zusätzliche Dichtringe zwischen Relais und Stecksockel einzusetzen, um die Steckverbindung zu schützen.However, if a relay is inserted into a socket, such as this is common in motor vehicles, for example, remains the plug connection between the relay and the socket is unprotected, even if the relay itself is sealed. Because such Plug-in base, especially in the engine compartment of motor vehicles, often exposed to heavy soiling or moisture are, it has been common to place additional sealing rings between Relay and socket to insert the plug connection to protect.

Aus der EP 0 400 434 B1 ist es weiterhin bekannt, zum Anschluß eines elektrischen Bausteins, insbesondere eines Relais, ein zusätzliches Übergehäuse zu verwenden, in welches das Relais eingesetzt wird. Das Übergehäuse besitzt an zwei Seiten eine Abdichtung, nämlich zum einen im Bereich der Steckverbindung, wo in einem Überlappungsbereich zwischen Stecksockel und Übergehäuse ein Radialdichtung vorgesehen ist, und zum anderen an der gegenüberliegenden offenen Gehäuseseite, wo ein Verschlußdeckel mittels eines eingelegten Dichtungsrings dicht eingesetzt ist. Ein derartiges Übergehäuse bedingt jedoch einen erheblichen zusätzlichen Fertigungs- und Materialaufwand, abgesehen von dem großen Platzbedarf.From EP 0 400 434 B1 it is also known for connection an electrical component, in particular a relay, to use an additional housing, in which the relay is used. The outer casing has two Sides a seal, namely on the one hand in the area of Plug connection, where in an overlap area between A radial seal is provided in the base and outer housing and on the other side on the open housing side, where a cover by means of an inserted Sealing ring is inserted tightly. Such an outer casing however requires a considerable additional manufacturing and material expenditure, apart from the large space requirement.

Ziel der vorliegenden Erfindung ist es, eine einfache Abdichtung zwischen einem steckbaren Relais und dem zugehörigen Stecksockel zu schaffen, die nur geringe konstruktive Veränderungen erfordert und bei der Steckmontage ohne zusätzliche Einzelteile, wie Dichtungsringe und dergleichen, auskommt.The aim of the present invention is to provide a simple seal between a pluggable relay and the associated one To create plug-in bases that have only minor design changes required and with plug-in assembly without additional Individual parts, such as sealing rings and the like, get by.

Erfindungsgemaß wird dieses Ziel dadurch erreicht, daß zumindest das eine der beiden Gehäuse aus einem formstabilen, thermoplastischen Kunststoff besteht und in einem dem anderen Gehäuse zugewandten, die Steckerstifte und Stecköffnungen umschließenden Randzone einen einstückig angeformten Dichtring aus Elastomer trägt und daß die beiden Gehäuse mittels übereinandergreifender Wandelemente unter elastischer Deformation des Dichtrings form- und/oder kraftschlüssig miteinander verbunden sind.According to the invention, this goal is achieved in that at least one of the two housings made of a dimensionally stable, thermoplastic material and one in the other Housing facing, the plug pins and plug openings enclosing Edge zone a one-piece molded sealing ring made of elastomer and that the two housings by means of overlapping Wall elements under elastic deformation the sealing ring is positively and / or non-positively connected are.

Da die Gehäusekappen derartiger Relais und auch die Gehäuse von Steckfassungen in der Regel ohnehin aus thermoplastischem, formstabilem Kunststoff hergestellt werden, bedingt die zusätzlich Anformung eines thermoplastischen, elastomeren Dichtrings im Zweikomponenten-Spritzverfahren nur einen geringen zusätzlichen Herstellungsaufwand. Das jeweils andere Gehäuse, das also den Dichtring nicht trägt, bleibt ohnehin völlig unverändert. Wenn der Dichtring an dem Stecksockel angeformt ist, könnte die Kappe des Relaisgehauses sogar aus Metall bestehen.Because the housing caps of such relays and also the housing of jacks usually made of thermoplastic anyway dimensionally stable plastic can be produced the additional molding of a thermoplastic, elastomer Sealing rings in the two-component spraying process only a small one additional manufacturing effort. The other The housing, which does not carry the sealing ring, remains anyway completely unchanged. When the sealing ring is molded onto the plug base the cap of the relay housing could even be out Metal.

Je nach den individuellen Gegebenheiten kann der Dichtring entweder an der Relaiskappe angeformt sein und dessen unteren Rand bilden, oder er kann dem Rand der Relaiskappe gegenüberliegend in die ebene Oberseite des Stecksockels vertieft eingelassen sein. Er kann aber auch als Radialdichtung im Überlappungsbereich zwischen Stecksockel und Relaiskappe an dem einen oder anderen Teil angeformt sein.Depending on the individual circumstances, the sealing ring can either be molded onto the relay cap and its lower one Form edge, or it can be opposite the edge of the relay cap recessed into the flat top of the socket be. But it can also be used as a radial seal in the overlap area between socket and relay cap on the be molded on one part or the other.

    • In Figur 1 ist die Anordnung eines Relais 1 auf einem Stecksockel 2 gezeigt. Das Relais besitzt ein Gehäuse mit einer Gehäusekappe 11 und einer Bodenplatte 12, in welcher Steckerstifte 13 verankert sind. Diese Steckerstifte sind als Flachstecker ausgebildet, wie diese in Figur 3 zu erkennen ist.In Figure 1, the arrangement of a relay 1 on a plug base 2 shown. The relay has a housing with a Housing cap 11 and a base plate 12, in which connector pins 13 are anchored. These connector pins are flat tabs trained, as can be seen in Figure 3.

    Der Stecksockel 2 besitzt ein Gehäuse 21 mit Kammern 22, in denen Steckerbuchsen 23 angeordnet sind. Die Kammern 22 münden zur Oberseite des Gehäuses 22 in Stecköffnungen 24, durch welche die Steckerstifte 13 des Relais eingeführt werden. An der Unterseite des Gehäuses 21 sind Anschlußdrähte 25 herausgeführt, welche im Innern auf nicht dargestellte Weise mit den Steckerbuchsen 23 verbunden sind.The plug-in base 2 has a housing 21 with chambers 22, in which sockets 23 are arranged. The chambers 22 open out to the top of the housing 22 in plug openings 24, through which the connector pins 13 of the relay are inserted. On lead wires 25 are led out from the underside of the housing 21, which inside with not shown the sockets 23 are connected.

    Zur Abdichtung der Steckverbindung zwischen dem Relais 1 und dem Stecksockel 2 ist an der Gehäusekappe 11, und zwar an deren unterem Rand, ein stegförmiger Dichtring 14 angeformt. Dieser Dichtring 14 besteht aus einem elastomeren Thermoplast, während die Gehäusekappe 11 ansonsten aus einem formstabilen Thermoplast besteht. Auf diese Weise ist es möglich, in einem Zweikomponenten-Spritzverfahren die Gehäusekappe mit dem Dichtring in einem Stück herzustellen. Zur Erzeugung des erforderlichen Anpreßdruckes auf den Dichtring 14 ist die Gehäusekappe außerdem mit Rastnasen 15 versehen, welche in Haltelaschen 26 des Stecksockels einrasten. Wie in Figur 1 zu sehen ist, wird durch diese Verrastung der Dichtring 14 elastisch deformiert, wodurch sich die gewünschte Abdichtung der beiden Gehäuse ergibt. To seal the plug connection between relay 1 and the plug-in base 2 is on the housing cap 11, specifically on the latter lower edge, a web-shaped sealing ring 14 is formed. This sealing ring 14 consists of an elastomeric thermoplastic, while the housing cap 11 otherwise from a dimensionally stable thermoplastic. In this way it is possible the housing cap in a two-component spraying process with the sealing ring in one piece. For generation of the required contact pressure on the sealing ring 14 the housing cap is also provided with locking lugs 15 which engage in retaining tabs 26 of the socket. As in figure 1 can be seen, the locking ring turns the sealing ring 14 elastically deformed, which creates the desired seal of the two housings.

    Eine abgewandelte Ausführungsform ist in den Figuren 4 und 5 gezeigt. Der Aufbau des Relais 1 und des Stecksockels 2 ist weitgehend der gleiche wie in Figur 1. Die Abdichtung erfolgt jedoch hier in komplementärer Weise. Anstelle des Dichtrings 14 an der Relaiskappe ist nunmehr ein Dichtring 27 in die ebene Oberseite des Stecksockel-Gehäuses 21 vertieft eingespritzt. Durch die Verrastung der Rastnasen 15 in den Haltelaschen 26 wird der untere Rand 16 der Gehäusekappe 11 in den Dichtring 27 eingedrückt, wodurch die gewünschte Abdichtung erzielt wird.A modified embodiment is shown in FIGS. 4 and 5 shown. The structure of relay 1 and socket 2 is largely the same as in Figure 1. The sealing is done but here in a complementary way. Instead of the sealing ring 14 on the relay cap is now a sealing ring 27 in the injected flat top of the plug-in housing 21 deepened. By locking the locking lugs 15 in the retaining tabs 26, the lower edge 16 of the housing cap 11 in the Sealing ring 27 pressed in, creating the desired seal is achieved.

    In den Figuren 6 und 7 ist eine weitere Abwandlung gezeigt. Hierbei greift die Relaiskappe 11 mit einem nach unten angeformten Kragen 17 über das Sockelgehause 21, welches einen radialen Dichtungsring 28 trägt, der umlaufend in eine Vertiefung der Seitenwand eingespritzt ist. Die elastische Deformation des Dichtrings 28 ergibt sich durch das kraftschlüssige Aufstecken des Kragens 17 auf das Sockelgehause 21. In Figur 6 ist außerdem andeutungsweise noch gezeigt, daß für die dichte Durchführung der Anschlußdrähte 25 jeweils Ringdichtungen 29 im Sockelgehause 21 vorgesehen sind. Diese Ringdichtungen 21 können in gleicher Weise wie die radialen Dichtringe 28 einstückig in einem Zweikomponenten-Spritzverfahren am Sockelgehause 21 angeformt werden.A further modification is shown in FIGS. 6 and 7. Here, the relay cap 11 engages with a molded-on downward Collar 17 over the base housing 21, which one radial sealing ring 28 carries, all the way into a recess the side wall is injected. The elastic deformation of the sealing ring 28 results from the non-positive Push the collar 17 onto the base housing 21. In FIG. 6 it is also indicated that for the tight implementation of the connecting wires 25 each Ring seals 29 are provided in the base housing 21. This Ring seals 21 can be made in the same way as the radial ones Sealing rings 28 in one piece in a two-component spraying process be molded onto the base housing 21.

    In Figur 8 ist eine Ansicht von oben auf ein abgewandeltes Sockelgehause 31 gezeigt, welches ebenfalls wie das in Figur 7 gezeigte rechteckige Gehäuse mit einer Radialdichtung, in diesem Fall mit einem Dichtring 38, versehen sein kann. Dieses Steckergehäuse wäre für ein Relais geeignet, welches ebenfalls einen entsprechend runden Querschnitt aufwiese.In Figure 8 is a top view of a modified Socket housing 31 shown, which also like that in Figure 7 shown rectangular housing with a radial seal, in this case can be provided with a sealing ring 38. This Plug housing would be suitable for a relay, which also had a correspondingly round cross-section.

    In Figur 9 ist eine weitere Abwandlung einer Relais-Stecksockel-Anordnung ähnlich Figur 6 gezeigt. In diesem Fall greift das Sockelgehause 21 mit einem nach oben angeformten Kragen 30 über die Kappe 11 des Relais. Im Überlappungsbereich zwischen dem Kragen 30 und der Kappe 11 ist ein Dichtring 18 vorgesehen, der wiederum aus elastomerem Material einstückig im Zweikomponenten-Spritzgußverfahren mit der Relaiskappe 11 verbunden ist. Anstelle des Dichtrings 18, wie er in Figur 9 auf der linken Seite der Kappe 11 gezeigt ist, kann auch ein Dichtring 19 gemäß Darstellung auf der rechten Seite von Figur 9 verwendet werden. Dieser greift zusätzlich dachförmig über den oberen Rand des Kragens 30 und verhindert damit, daß Wasser oder Schmutz sich in den Spalt zwischen Relais-Gehäusekappe 11 und Sockel-Kragen 30 absetzen können. Ansonsten sind sowohl das Relais 1 als auch der Stecksockel 2 wie in den übrigen Beispielen aufgebaut.FIG. 9 shows a further modification of a relay socket arrangement shown similar to Figure 6. In this case grips the base housing 21 with an integrally molded upward Collar 30 over the cap 11 of the relay. In the overlap area between the collar 30 and the cap 11 is a sealing ring 18 provided, which in turn made of elastomeric material in one piece in two-component injection molding with the relay cap 11 is connected. Instead of the sealing ring 18, like it is shown in FIG. 9 on the left side of the cap 11, can also be a sealing ring 19 as shown on the right Page of Figure 9 can be used. This also applies roof-shaped over the upper edge of the collar 30 and prevented so that water or dirt gets into the gap between the relay housing cap 11 and base collar 30 can settle. Otherwise, both relay 1 and socket 2 are as constructed in the other examples.
