Description

Die Erfindung betrifft einen Stecksockel gemäß dem Oberbegrifs des Anspruchs 1. Ein solcher Stecksockel ist aus CH-A-387 121 bekannt.The invention relates to a plug-in base according to the preamble of claim 1. Such a socket is out CH-A-387 121 known.

Derartige Stecksockel sind beispielsweise in der Automobil-Elektrik vielfach im Einsatz. Insbesondere für dieses Anwendungsgebiet haben sich Standardabmessungen herausgebildet, beispielsweise Standardbreiten für die Flachstecker von 6,3 mm, 4,8 mm und 2,8 mm. Entsprechend den Steckerabmessungen sind auch für die Kontaktkammern in den Stecksockeln und für die Kontaktbuchsen in den Kammern die jeweils entsprechenden Standard-Abmessungen vorgesehen. Dabei werden üblicherweise Kontaktbuchsen eingesetzt, wie sie in Steckverbindern üblich sind.Such sockets are used, for example, in automotive electronics widely used. Especially for this area of application standard dimensions have developed, For example, standard widths for the tabs of 6.3 mm, 4.8 mm and 2.8 mm. According to the connector dimensions are also for the contact chambers in the sockets and for the contact sockets in the chambers are the corresponding ones Standard dimensions provided. This is usually done Contact sockets used, as they are common in connectors are.

Eine Kontaktbuchse mit beidseitiger Verrastung über Rastzungen ist beispielsweise ganz allgemein in der DE 88 11 020 U1 gezeigt. Durch die beidseitige Verrastung der Kontaktbuchse benötigen die Kontaktkammern einschließlich der Rastnuten erheblich mehr Platz in Querrichtung zur Steckerebene, als dies durch die Steckerdicke und die Federzungen erforderlich wäre. Dies wirkt sich auf den Abstand von benachbarten Steckschlitzen aus. A contact socket with double-sided locking via locking tongues is, for example, very general in DE 88 11 020 U1 shown. By locking the contact socket on both sides need the contact chambers including the locking grooves considerably more space in the transverse direction to the plug level than this would be required by the plug thickness and the spring tongues. This affects the distance from adjacent slots out.

Für die Außenkonturen und für die Anschlußkonfiguration von Relais in Automobilen haben sich ebenfalls Standardabmessungen herausgebildet. Normalerweise besitzen Automobilrelais vier oder fünf Anschlußstecker, nämlich zwei Anschlüsse für die Spule und zwei Anschlüsse für einen Schließer- oder Öffner-Kontakt bzw. drei Anschlüsse für den Wechsler. Bei den üblichen Standardrelais ist somit für fünf Standardanschlüsse in den entsprechenden Stecksockeln genügend Platz, wobei sich auch für die Kontaktkammern entsprechende Standardabmessungen herausgebildet haben.For the outer contours and for the connection configuration of Relays in automobiles also have standard dimensions formed. Usually have automotive relays four or five connectors, namely two connectors for the coil and two connections for a normally open or normally closed contact or three connections for the changer. Both usual standard relay is therefore for five standard connections enough space in the corresponding plug-in bases Corresponding standard dimensions also for the contact chambers have formed.

Mit der ständig zunehmenden Anzahl von Relais, die in Automobilen eingesetzt werden, ergeben sich jedoch mehr und mehr Platzprobleme für deren Einbau. Da für viele Anwendungen aber die hohen Schaltleistungen, die ein Standardrelais bewältigt, nicht erforderlich sind, wurden verkleinerte Relaistypen entwickelt, die annähernd die halbe Fläche eines Standardrelais bedecken, so daß durch ihren Einsatz Bauraum eingespart wird; dies soll aber so geschehen, daß auf dem Platz eines Standardrelais zwei Kleinrelais untergebracht werden können, damit das Gesamtraster der Relaisanschlußeinheiten beibehalten werden kann. Für zwei Relais mit jeweils nur einem Schließer-oder Öffner-Kontakt sind die entsprechenden Kontaktkammern in einem Stecksockel mit Standard-Abmessungen ohne weiteres unterzubringen. Dagegen ergeben sich für Relais mit Wechslerkontakt Schwierigkeiten, auf dem zur Verfügung stehenden Platz drei Kontaktkammern in Standardgröße mit entsprechenden Standard-Steckbuchsen unerzubringen, da diese beidseitig verrasteten Steckbuchsen, wie oben erwähnt, eine relativ große Breite beanspruchen.With the ever increasing number of relays used in automobiles are used, however, arise more and more Space problems for their installation. As for many applications the high switching capacities that a standard relay can handle, smaller relay types have been developed, which is almost half the area of a standard relay cover so that space is saved through their use; but this should be done so that on the place of a standard relay two small relays can be accommodated so maintain the overall grid of the relay connection units can be. For two relays with only one make contact or each NC contacts are the corresponding contact chambers in easily accommodate a plug-in base with standard dimensions. In contrast, there are relays with changeover contacts Difficulties on the available Place three standard size contact chambers with corresponding ones Standard receptacles are unsuitable because they latched on both sides Sockets, as mentioned above, a relatively large one Claim width.

Es wurde zwar hierzu bereits vorgeschlagen, Steckbuchsen mit nur einseitiger Verrastung zu verwenden, wie sie beispielsweise in der erwähnten EP 0 007 709 B1 gezeigt sind. Eine solche Ausführungsform käme mit geringerer Weite der Kontaktkammern aus, bietet jedoch nicht die gewünschte Sicherheit wie eine zweiseitige Verriegelung. In diesem Dokument ist auch eine zusätzliche Sekundärsicherung in einem Steckverbindergehäuse dargestellt.It has already been proposed to do this with sockets to use only one-sided locking, such as are shown in the mentioned EP 0 007 709 B1. A such an embodiment would come with a smaller width of the contact chambers off, but does not offer the desired security like a two-sided locking. In this document is also an additional secondary fuse in a connector housing shown.

Ziel der vorliegenden Erfindung ist es deshalb, einen Stecksockel der eingangs genannten Art zur Aufnahme von mindestens einem Relais, vorzugsweise jedoch von zwei oder mehr Relais, zu schaffen, bei dem Standard-Steckbuchsen mit zweiseitiger Verrastung in standardmäßigen Kontaktkammern platzsparend nebeneinander angeordnet werden können.The aim of the present invention is therefore a plug-in base of the type mentioned at the beginning to accommodate at least one relay, but preferably two or more relays, to create the standard sockets with two-sided Locking in standard contact chambers next to each other to save space can be arranged.

Erfindungsgemäß wird dieses Ziel durch einem Stecksockel nach Anspruch 1 erreicht.According to the invention this goal is achieved by a plug-in base according to claim 1.

Bei der Erfindung werden also die Rastnuten der nebeneinanderliegenden Kontaktkammern gegeneinander versetzt oder verschachtelt angeordnet, so daß die jeweilige Trennwand nicht die doppelte Tiefe einer Rastnut und zusätzlich die erforderliche Isolationsdicke aufweisen muß, sondern daß diese Rastnuten aneinander vorbei an unterschiedlichen Stellen in die Trennwand eingreifen. Die Trennwand zwischen je zwei Kontaktkammern kann somit auch mit geringerer Dicke die erforderliche Isolation und mechanische Festigkeit gewährleisten. Ermöglicht wird dies durch die Verwendung von schmäleren Kontaktbuchsen im Vergleich zu den breiteren Flachsteckern des Relais, wodurch die Steckbuchsen im Vergleich zu den Flachsteckern selbst jeweils versetzt angeordnet werden können. In the invention, the locking grooves are the side by side Contact chambers offset or nested against each other arranged so that the respective partition is not twice the depth of a locking groove and additionally the required Insulation thickness must have, but that these locking grooves past each other in different places in the Intervene. The partition between two contact chambers can therefore also be required with a smaller thickness Ensure insulation and mechanical strength. Allows this is achieved through the use of narrower contact sockets compared to the wider tabs of the Relay, which makes the sockets compared to the flat plugs themselves can be staggered.

Dabei wird auch die Tatsache genutzt, daß die standardmäßigen Steckerquerschnitte mit der entsprechenden Breite für viele Einsatzzwecke mit geringerer Schaltstromstärke nicht erforderlich ist. Für diese Einsatzfälle reichen die schmäleren Steckbuchsen im Sockel aus. Die breiteren Flachstecker werden also in schmälere Buchsen eingesteckt, die jedoch nicht zentrisch zu diesen, sondern abwechselnd zu den Seitenkanten hin versetzt liegen.The fact that the standard Connector cross sections with the appropriate width for many Applications with a lower switching current are not required is. The narrower ones are sufficient for these applications Sockets in the base. The wider tabs will be So plugged into narrower sockets, but not centrically towards these, but alternately towards the side edges lie staggered.

Um eine bei Stecksockeln für Automobilrelais in vielen Fällen geforderte Sekundärverriegelung der Steckbuchsen zu erreichen, ist in einer bevorzugten Ausführungsform in an sich bekannter Weise vorgesehen, daß in dem Gehäuse jeweils unterhalb der Kontaktkammer-Anordnung für ein Relais ein Sekundärverriegelungs-Schieber angeordnet ist, der unterhalb einer jeden Kontaktkammer einen durchgehenden Steckschacht aufweist und senkrecht zur Steckachse zwischen einer Montageposition und einer Endposition verschiebbar ist, derart, daß in der Montageposition jeder Steckschacht jeweils mit der zugehörigen Kontaktkammer fluchtet, um das Durchstecken einer Kontaktbuchse zu ermöglichen, und daß in der Endposition eine Verriegelungskante des Schieber seinen Teil des Kontaktkammer-Querschnitts überdeckt, um eine eingesteckte Kontaktbuchse zu verriegeln.In many cases with plug-in sockets for automotive relays to achieve the required secondary locking of the sockets, is in a preferred embodiment known per se Way provided that in the housing each below the contact chamber arrangement for a relay a secondary locking slide is arranged below one each contact chamber has a continuous slot and perpendicular to the thru axle between an assembly position and an end position is displaceable, such that in the Mounting position of each slot with the corresponding one Contact chamber is aligned to insert a contact socket to enable, and that in the final position Locking edge of the slide its part of the contact chamber cross-section covered to an inserted contact socket to lock.

Vorzugsweise bildet der Grundkörper für jeden Verriegelungsschieber eine Verriegelungskammer, wobei die einander gegenüberliegenden Seitenwände des Grundkörpers einerseits und des Schiebers andererseits ineinandergreifende Rastelemente zur Vorverrastung des Schiebers in der Montageposition und zur Verriegelung in der Endposition aufweisen.The base body preferably forms for each locking slide a locking chamber, the opposite one another Side walls of the base body on the one hand and the Slider on the other hand interlocking locking elements for Prelocking of the slide in the assembly position and for Have locking in the end position.

Die Erfindung wird nachfolgend an Ausführungsbeispielen anhand der Zeichnung näher erläutert. Es zeigt

  • Figur 1 zeigt in einer Übersichtsdarstellung die Montagefolge eines erfindungsgemäß gestalteten Stecksockels. Ein Grundkörper 1 weist an seiner Oberseite Steckschlitze für die Aufnahme von zwei Relais 2 auf, welche identisch aufgebaut, aber um 180° gegeneinander verdreht nebeneinander angeordnet werden. Jedes dieser Relais besitzt zwei breite Flachstecker 3 und 4 und drei quer dazu mit ihren Hauptebenen parallel, miteinander in einer Reihe fluchtend angeordnete Kontaktanschlüsse in Form von Flachsteckern 5, 6 und 7. Zur Aufnahme dieser Flachstecker besitzt der Grundkörper 1 von seiner Oberseite nach innen gehende Steckschlitze 13, 14 sowie die parallel in einer Reihe liegenden Steckschlitze 15, 16 und 17 für jedes Relais. In Figur 2 sind diese Steckschlitze genauer zu erkennen.Figure 1 shows an overview of the assembly sequence a plug-in base designed according to the invention. A basic body 1 has plug slots on its top for receiving of two relays 2, which are constructed identically, but around 180 ° rotated side by side. Each of these relays has two wide tabs 3 and 4 and three across it with their main planes parallel, with each other Contact connections aligned in a row in Form of tabs 5, 6 and 7. To accommodate these tabs has the base body 1 from its top internal slots 13, 14 and parallel in one Row of slots 15, 16 and 17 for each relay. These plug-in slots can be seen more precisely in FIG.

    Von der Unterseite werden zwei Sekundärverriegelungs-Schieber 8 in entsprechende Verriegelungskammern 9 eingeschoben, wie später anhand der Figuren 4 und 5 noch erläutert werden wird. Durch die Sekundär-Verriegelungsschieber 8 hindurch werden dann in entsprechende Kontaktkammern jeweils den Flachstekkern zugeordnete Steckbuchsen eingeschoben. Entsprechend den Flachsteckern 3 und 4 werden in Kontaktkammern 23 und 24 zwei gleiche Steckbuchsen 33 eingesteckt, die in bekannter Weise an die Breite der Flachstecker 3 und 4 angepaßt sind. Sie besitzen an ihren unteren Enden jeweils Crimp- oder Klemmhülsen 34, mit denen in bekannter Weise Anschlußdrähte kontaktiert werden können.From the bottom there are two secondary locking slides 8 inserted into corresponding locking chambers 9, such as will be explained later with reference to Figures 4 and 5. Be through the secondary locking slide 8 then the respective flat core in corresponding contact chambers assigned sockets inserted. According to the Tabs 3 and 4 are two in contact chambers 23 and 24 same sockets 33 inserted in a known manner are adapted to the width of the tabs 3 and 4. You own crimp or clamping sleeves at their lower ends 34, with which contact wires are contacted in a known manner can be.

    Unterhalb der Steckschlitze 15, 16 und 17 werden in entsprechende Kontaktkammern 25, 26 und 27 drei identische Steckbuchsen 35 eingesteckt. Diese Steckbuchsen 35 sind ebenfalls in bekannter Weise aufgebaut mit einer Crimp- oder Klemmhülse 36 an der Unterseite zur Kontaktierung eines Anschlußdrahtes und mit gabelförmigen Federarmen 37 an ihrer Oberseite, die an ihren Enden zur Einführung der Flachstecker schwalbenschwanzförmig auseinandergebogen sind. Eine kastenförmige Überfeder 38 dient zur Erzeugung des Kontaktdruckes auf die Federzungen 37. Außerdem sind an der Überfeder nach beiden Seiten Rastzungen 39 nach unten auswärts gebogen, die sich nach dem Einschieben der Kontaktbuchse in die jeweilige Kontaktkammer nach außen spreizen und so eine beidseitige Verrastung in den noch zu beschreibenden Rastnuten 40 bzw. 41 bewirken.Below the slots 15, 16 and 17 are in corresponding Contact chambers 25, 26 and 27 three identical sockets 35 inserted. These sockets 35 are also constructed in a known manner with a crimp or clamping sleeve 36 on the underside for contacting a connecting wire and with fork-shaped spring arms 37 on their top, the dovetail-shaped at their ends for insertion of the tabs are bent apart. A box-shaped Overspring 38 serves to generate the contact pressure on the Spring tongues 37. In addition, on the over-spring after both Sides of locking tabs 39 are bent downwards outwards after inserting the contact socket into the respective contact chamber spread outwards and thus locks on both sides in the locking grooves 40 and 41 to be described cause.

    Wie sich insbesondere aus den Figuren 2 und 3 ergibt, sind die Steckschlitze 15, 16 und 17 in einer Reihe fluchtend nebeneinander angeordnet, also mit ihren Hauptebenen parallel, wobei ihre Breite b1 jeweils der Breite der Flachstecker 5, 6 und 7 entspricht. Die Kontaktkammern 25, 26 und 27 besitzen jedoch ebenso wie die in ihnen befestigten Kontaktbuchsen 35 eine geringere Breite b2, wobei diese Kontaktkammern jeweils abwechselnd entgegengesetzt zu den Enden der Steckschlitze hin versetzt angeordnet sind. Die Rastzungen 39 der Kontaktbuchsen 35 verrasten jeweils in Rastnuten 40 und 41 zu beiden Seiten einer jeden Kontaktkammer 25, 26 und 27, und zwar oberhalb jeweils einer Rastkante 42. Die Rastzungen 39 sind in ihrer Breite an die Breite b3 der Rastnuten 40 und 41 angepaßt. Die Federzungen 37 der Kontaktbuchsen besitzen eine Breite b4; sie sind in ihren Seitenbereichen durch Abdeckstege 43 der Steckschlitze überdeckt. In Figur 2 ist in der rechten Hälfte der Grundkörper in Draufsicht ohne Bestückung mit Kontaktbuchsen gezeigt, während im linken Teil dieser Figur in der Draufsicht die von unten eingesteckten Kontaktbuchsen 33 und 35 zu sehen sind.As can be seen in particular from FIGS. 2 and 3, are the slots 15, 16 and 17 in a row aligned side by side arranged, so with their main planes parallel, their width b1 being the width of the tabs 5, 6 and 7 corresponds. The contact chambers 25, 26 and 27 have however, just like the contact sockets 35 fastened in them a smaller width b2, these contact chambers each alternately opposite to the ends of the slots are arranged offset. The locking tongues 39 of the contact sockets 35 latch in both locking grooves 40 and 41 to both Sides of each contact chamber 25, 26 and 27, namely above a respective locking edge 42. The locking tongues 39 are adjusted in width to the width b3 of the locking grooves 40 and 41. The spring tongues 37 of the contact sockets have one Width b4; they are in their side areas by cover webs 43 of the slots covered. In Figure 2 is in the right half of the base body in plan view without equipment shown with contact sockets, while in the left part of this figure in the top view the plugged-in contact sockets 33 and 35 can be seen.

    Durch die versetzte Anordnung der Kontaktkammern 25, 26 und 27 sind auch die zugehörigen Rastnuten 40 und 41 abwechselnd in Breitenrichtung der Steckschlitze versetzt. Dadurch brauchen die Trennwände 44 und 45 zwischen je zwei Kontaktkammern bzw. Steckschlitzen nicht die volle Tiefe von zwei Rastnuten aufzunehmen. Die Rastnut 41 der Kontaktkammer 25 erstreckt sich somit ohne Überlappung neben der Rastnut 40 der Kontaktkammer 26. Die einander zugewandten Ecken der beiden Rastnuten sind im gezeigten Beispiel abgeschrägt, um auch in diesem Bereich eine genügend dicke Isolationswand zwischen beiden Nuten zu erhalten. Da die Rastzungen 39 ohnehin etwas schmäler sind als die Breite der Nut, beeinträchtigt die Abschrägung 46 die Funktion der eingesteckten Kontaktbuchsen nicht.Due to the offset arrangement of the contact chambers 25, 26 and 27, the associated locking grooves 40 and 41 are alternating offset in the width direction of the slots. Thereby need the partitions 44 and 45 between two contact chambers or plug-in slots not the full depth of two locking grooves to record. The locking groove 41 of the contact chamber 25 extends thus without overlap next to the locking groove 40 of the contact chamber 26. The mutually facing corners of the two locking grooves are bevelled in the example shown to also in this Area of a sufficiently thick insulation wall between the two To get grooves. Since the locking tongues 39 are somewhat narrower anyway than the width of the groove affects the bevel 46 the function of the inserted contact sockets is not.

    Durch den Versatz der Kontaktbuchsen in den zugehörigen Kontaktkammern ergibt sich, daß die Federzungen 37 die zugehörigen Flachstecker 5, 6 und 7 nicht über deren gesamte Breite und auch nicht mittig kontaktieren, sondern jeweils nur über etwa zwei Drittel ihrer Breite, und zwar abwechselnd einmal von der einen Seite und einmal von der anderen Seite. Da die Flachstecker aber aus Gründen der Standardisierung ohnehin breiter ausgelegt sind als für den Normalfall notwendig, reicht diese Kontaktierung für die meisten Fälle aus.Due to the offset of the contact sockets in the associated contact chambers it follows that the spring tongues 37 the associated Flat plugs 5, 6 and 7 are not over their entire width and also do not contact in the middle, but only via about two thirds of its width, alternately once from one side and once from the other side. Since the Flat plugs anyway for reasons of standardization are designed wider than is necessary for normal use, this contact is sufficient in most cases.

    Die Kontaktbuchsen erhalten in bekannter Weise eine zusätzliche Sekundärverriegelung mittels der Sekundärveriegelungs-Schieber 8, wie oben bereits erwähnt. Diese Verriegelung sei anhand der Figuren 4 und 5 noch kurz beschrieben. Jeder Schieber 8 besitzt im Bereich unterhalb einer jeden Kontaktkammer einen durchgehenden Steckschacht, also zwei Steckschächte 53 und 54 unterhalb der Kontaktkammern 23 und 24 sowie Steckschächte 55, 56 und 57 unterhalb der Kontaktkammern 25, 26 und 27. Die Steckschächte 54 und 56 gehen ineinander über. Sie werden bei dem vorliegenden Ausführungsbeispiel erst nach dem Zusammenstecken durch eine am Grundkörper angeformte Trennwand 58 isoliert. Jeder der beiden Schieber 8 wird in eine zugehörige Verriegelungskammer 59 bzw. 60 des Grundkörpers 1 von unten eingesetzt, und zwar vor der Montage der Kontaktbuchsen. Sie befinden sich dabei in einer Vorverriegelungsstellung, wobei an den Seiten der Schieber 8 angeformte Verriegelungsnasen 61 in eine Vorverriegelungskerbe 62 des Grundkörpers eingreifen. In dieser in Figur 5 gezeigten Montageposition fluchten die Steckschächte 53 bis 57 jeweils mit den darüberliegenden Kontaktkammern 23 bis 27. In dieser Position werden also die mit ihren zugehörigen Anschlußdrähten bestückten Steckbuchsen durch die Steckschächte in die darüberliegenden Kontaktkammern eingesteckt. Danach werden die beiden Schieber 8 quer zur Steckrichtung in Richtung der Pfeile 10 in Figur 5 verschoben, wobei die Verriegelungsnasen 61 in die Rastkerben 63 gelangen und dort eine Endposition der Schieber 8 verriegeln. Bei dieser Verschiebung gelangen in den einzelnen Steckschächten vorgesehene Verriegelungsleisten 64 unter die kastenförmigen Überfedern 38 und sichern so die Kontaktbuchsen zusätzlich in ihrer jeweiligen Kontaktkammer.The contact sockets receive an additional in a known manner Secondary locking by means of the secondary locking slide 8, as mentioned above. This lock is described briefly with reference to Figures 4 and 5. Everyone Slider 8 has in the area below each contact chamber a continuous slot, i.e. two slots 53 and 54 below the contact chambers 23 and 24 as well Push-in shafts 55, 56 and 57 below the contact chambers 25, 26 and 27. The slots 54 and 56 merge about. You will in the present embodiment only after plugging together by a molded on the base body Partition 58 isolated. Each of the two slides 8 is in an associated locking chamber 59 or 60 of the Base body 1 inserted from below, before assembly the contact sockets. You are in a pre-locked position, being formed on the sides of the slide 8 Locking lugs 61 into a pre-locking notch 62 of the main body. In this shown in Figure 5 Installation position align the slots 53 to 57 each with the overlying contact chambers 23 to 27. In this So position with their associated connecting wires equipped sockets through the slots in the inserted contact chambers above. After that the two sliders 8 transverse to the direction of insertion in the direction of Arrows 10 shifted in Figure 5, the locking tabs 61 get into the notches 63 and there an end position lock the slide 8. Arrive at this shift Locking strips provided in the individual slots 64 under the box-shaped springs 38 and so secure the contact sockets in their respective contact chamber.

    Die Erfindung wurde beispielshalber für zwei Relais mit jeweils einem Wechslerkontakt beschrieben; grundsätzlich ist diesen Prinzip der Verschachtelung der Kontaktkammern jedoch auch auf andere Ausführungsformen anwendbar, beispielsweise auf Relais mit vier oder mehr Kontaktanschlüssen, wie beispielsweise für zwei Schließerkontakte. Natürlich können in einem Sockel auch mehr als zwei Relais nebeneinander in der gleichen Weise untergebracht werden.The invention has been exemplified for two relays each a changeover contact described; is fundamental this principle of nesting the contact chambers also applicable to other embodiments, for example on relays with four or more contact connections, such as for two NO contacts. Of course, in a base also more than two relays next to each other in the same way.
