Description

Die vorliegende Erfindung geht von einem gemäß dem Oberbegriff des Hauptanspruches konzipierten elektrischen Steckverbindungsteil aus.The present invention is based on an electrical connector part designed according to the preamble of the main claim.

Derartige elektrische Steckverbindungsteile sind insbesondere dafür vorgesehen, um über ihre an elektrische Leitungen angeschlossenen Steckkontaktelemente eine wieder lösbare elektrische Verbindung zu einem Gegen-Steckverbindungsteil zu schaffen. Das Gegen-Steckverbindungsteil kann dabei z.B. ebenfalls an eine elektrische Leitung angeschlossen sein oder direkt mit einem elektrischen Aggregat in Verbindung stehen.Such electrical plug-in connection parts are provided in particular in order to create a releasable electrical connection to a mating plug-in connection part via their plug contact elements connected to electrical lines. The mating connector part can e.g. also be connected to an electrical line or directly connected to an electrical unit.

Durch die DE 43 01 602 C1 ist ein dem Oberbegriff des Hauptanspruches entsprechendes elektrisches Steckverbindungsteil bekanntgeworden. Bei diesem elektrischen Steckverbindungsteil werden die elektrischen Steckkontaktelemente in Aufnahmekammern des Gehäuses eingebracht, welches für jede Aufnahmekammer mit einem Verriegelungsarm versehen ist. Zur sogenannten sekundären Sicherung kann jeder Verriegelungsarm von einer Entriegelungsposition in eine Verriegelungsposition gebracht werden. Darüber hinaus sind an die elektrischen Steckkontaktelemente jeweils zwei Federarme angeformt, welche hinter an Wandungen der zugehörigen Aufnahmekammer angeformte Rastabsätze zu liegen kommen, so daß darüber die in den Aufnahmekammern befindlichen elektrischen Steckkontaktelemente primär gesichert gehalten sind. Soll eine elektrisches Steckverbindungselement aus seiner Aufnahmekammer entfernt werden, wird über entsprechende Zugänge ein Werkzeug in die zugehörige Aufnahmekammer eingeführt, wodurch die Primärverriegelung aufgehoben wird. Um das Steckkontaktelement aus seiner Aufnahmekammer entnehmen zu können, muß aber noch zusätzlich durch einen weiteren Arbeitsschritt die Sekundärverriegelung aufgehoben werden.From DE 43 01 602 C1 an electrical connector part corresponding to the preamble of the main claim has become known. In this electrical connector part, the electrical plug contact elements are introduced into receiving chambers of the housing, which is provided with a locking arm for each receiving chamber. For so-called secondary security, each locking arm can be of one Unlocking position are brought into a locking position. In addition, two spring arms are formed on the electrical plug-in contact elements, which come to rest behind locking projections formed on the walls of the associated receiving chamber, so that the electrical plug-in contact elements located in the receiving chambers are kept primarily secured. If an electrical connector element is to be removed from its receiving chamber, a tool is inserted into the associated receiving chamber via appropriate accesses, whereby the primary locking is released. In order to be able to remove the plug contact element from its receiving chamber, however, the secondary locking must also be released by a further work step.

Desweiteren ist durch die DE 41 24 541 A1 ein elektrisches Steckverbindungsteil bekannt geworden, in dessen Aufnahmekammern zur Verriegelung von eingebrachten Steckkontaktelementen elastisch auslenkbare Verriegelungsarme vorhanden sind. Die Verriegelungsarme sind an eine Gehäusewand angeformt und kommen zur Verriegelung mit ihrem freien Ende an einem Vorsprung der zugeordneten Steckkontaktelemente zuliegen. Um eine sichere Verriegelung zu erreichen, wird von der Steckseite her ein Distanzblock in den Innenraum des Steckverbindungsteiles eingeschoben, welcher in einer ersten Stellung ein elastisches Auslenken der Verriegelungsarme zuläßt und welcher in einer zweiten Stellung die Auslenkbarkeit der Verriegelungsarme sperrt. Soll nun ein Steckkontaktelement wieder aus seiner Aufnahmekammer entfernt werden, muß zunächst der Distanzblock wieder in seine erste Stellung gebracht werden, erst dann kann zum Auslenken des Verriegelungsarmes ein Werkzeug in den Innenraum des Steckverbindungsteiles eingeführt und das betreffende Steckkontaktelement aus seiner Aufnahmekammer entnommen werden. Wegen gänzlich fehlender gehäuseseitiger und steckkontaktelementseitiger Maßnahmen, ist mittels eines solchen Steckverbindungsteiles jedoch nur eine einzige Verriegelungsmaßnahme für die Steckkontaktelemente realisierbar. Zum Aufheben dieser sich lediglich auf eine Verriegelungsmaßnahme beziehenden Verriegelung sind jedoch mehrere Arbeitsschritte notwendig.Furthermore, from DE 41 24 541 A1 an electrical plug connector has become known, in the receiving chambers for locking inserted plug contact elements there are elastically deflectable locking arms. The locking arms are molded onto a housing wall and come to rest with their free end against a projection of the associated plug contact elements for locking. In order to achieve a secure locking, a spacer block is inserted into the interior of the connector part from the plug side, which allows elastic deflection of the locking arms in a first position and which blocks the deflectability of the locking arms in a second position. If a plug-in contact element is now to be removed again from its receiving chamber, the spacer block must first be brought back into its first position; only then can a tool be inserted into the interior of the plug-in connection part to deflect the locking arm and the relevant plug-in contact element can be removed from its receiving chamber. Because of completely missing housing and Measures on the plug contact element side, however, only a single locking measure for the plug contact elements can be implemented by means of such a plug connection part. In order to cancel this locking, which relates only to a locking measure, however, several work steps are necessary.

Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde ein elektrisches Steckverbindungsteil derart weiterzubilden, daß durch einen einzigen Arbeitsschritt sowohl die primäre als auch die sekundäre Verriegelung lediglich durch das Einführen eines einzigen Werkzeuges aufgehoben wird und somit eine schnelle, einfachen Entnahme von elektrischen Steckkontaktelementen aus ihren Aufnahmekammern möglich ist.Proceeding from this, the object of the present invention is to further develop an electrical plug connection part in such a way that both the primary and the secondary locking are released by the insertion of a single tool in a single work step and thus a quick, simple removal of electrical plug contact elements from their receiving chambers is possible.

Erfindungsgemäß wird die Aufgabe bei einem elektrischen Steckverbindungsteil der eingangs erwähnten Art durch die im kennzeichnenden Teil des Hauptanspruches angegebenen Merkmale gelöst.According to the invention the object is achieved in an electrical connector part of the type mentioned by the features specified in the characterizing part of the main claim.

Besonders vorteilhaft bei einer Verwendung von solchen elektrischen Steckverbindungsteilen ist, daß trotz einer besonders sicheren Verriegelung durch zwei Verriegelungsmaßnahmen eine schnelle und einfache Entnahmemöglichkeit von elektrischen Steckkontaktelementen auf kostengünstige Art und Weise realisiert ist.It is particularly advantageous when using such electrical plug-in connection parts that, despite a particularly secure locking by means of two locking measures, a quick and easy way of removing electrical plug-in contact elements is realized in a cost-effective manner.

Wie aus der Zeichnung hervorgeht, besteht ein solches elektrisches Steckverbindungsteil hauptsächlich aus einem aus Kunststoff hergestellte Gehäuse 1 in dem zumindest eine zur Aufnahme eines zugeordneten elektrischen Steckkontaktelementes 2 vorgesehene Aufnahmekammer 3 vorhanden ist. In zumindest einer äußeren Gehäusewand des Gehäuses 1 befindet sich je Aufnahmekammer 3 ein Durchbruch 4 mit einem darin angeordneten, einerseits einstückig an diese äußere Gehäusewand angeformten Verriegelungsarm 5.As can be seen from the drawing, such an electrical plug connection part mainly consists of a housing 1 made of plastic in which there is at least one receiving chamber 3 provided for receiving an associated electrical plug contact element 2. In at least one outer housing wall of the housing 1 there is an opening 4 for each receiving chamber 3 with a locking arm 5 arranged therein and integrally molded on one side onto this outer housing wall.

Die in den Aufnahmekammern 3 des Gehäuses 1 befindlichen elektrischen Steckkontaktelemente 2 müssen gesichert in denselben gehalten sein, damit nach dem Verbinden des Steckverbindungsteiles mit seinem Gegen-Steckverbindungsteil deren Funktionstüchtigkeit gewährleistet ist. Jedes Steckkontaktelement 2 weist dazu zwei angeformte Federarme 6 auf, die jeweils hinter einen an die Wandungen der zugehörigen Aufnahmekammern 3 angeformten Rastabsatzes 7 zu liegen kommen. Die beiden Federarme 6 und die beiden Rastabsätze 7 stellen bzgl. der notwendigen Positionssicherung des elektrischen Steckkontaktelementes 2 die sogenannte primäre Sicherung dar. Außerdem wird jedes elektrische Steckkontaktelement 2 zur Positionssicherung zusätzlich zwischen einem an den Mundbereich 13 der zugeordneten Aufnahmekammer 3 angeformten Endanschlag 8 und dem in seine Verriegelungsposition gebrachten Verriegelungsarm 5 gesichert gehalten. Dabei sorgt der mit seinem freien Ende an das elektrische Steckkontaktelement 2 zur Anlage kommende Verriegelungsarm 5 für die sogenannte sekundäre Sicherung. Jeder Verriegelungsarm 5 ist beweglich über ein Filmscharnier 9 an eine äußere Gehäusewand des Gehäuses 1 angeformt. Bei einreihigen Steckverbindungsteilen sind alle Verriegelungsarme 5 Bestandteil einer einzigen äußeren Gehäusewand, wohingegen bei zweireihigen Steckverbindungsteilen die Verriegelungsarme 5 Bestandteile zweier gegenüberliegender äußerer Gehäusewände des Gehäuses 1 sind.The electrical plug-in contact elements 2 located in the receiving chambers 3 of the housing 1 must be securely held in the same, so that their functionality is guaranteed after the plug-in connection part has been connected to its counter-plug-in connection part. For this purpose, each plug-in contact element 2 has two molded-on spring arms 6, each of which comes to rest behind a locking shoulder 7 molded onto the walls of the associated receiving chambers 3. Place the two spring arms 6 and the two locking shoulders 7 With regard to the necessary securing of the position of the electrical plug-in contact element 2, the so-called primary securing is provided. In addition, each electrical plug-in contact element 2 is additionally secured for securing the position between an end stop 8 formed on the mouth region 13 of the associated receiving chamber 3 and the locking arm 5 brought into its locking position. The free end of the locking arm 5 coming into contact with the electrical plug contact element 2 ensures the so-called secondary securing. Each locking arm 5 is movably formed on an outer housing wall of the housing 1 via a film hinge 9. In the case of single-row plug-in connection parts, all locking arms 5 are part of a single outer housing wall, whereas, in the case of double-row plug-in connection parts, the locking arms 5 are part of two opposite outer housing walls of the housing 1.

Der Einfachheit halber ist in der Zeichnung nur eine einzige Aufnahmekammer 3 des Gehäuses 1 dargestellt. Damit sich eine wirkungsvollen sekundäre Sicherung ergibt, ist der Verriegelungsarm 5 im wesentlichen L-förmig ausgebildet und kommt mit seinem kurzen Schenkel hinter an das zugeordnete Steckkontaktelement angeformte Sicherungsansätze 10 zu liegen. Wie insbesondere aus der Fig. 3 hervorgeht, ist in den kurzen Schenkel des Verriegelungsarmes 5 eine Rückstellschräge 11 eingeformt, die in ihrer Kontur im wesentlichen eine Verlängerung des langen Schenkels darstellt und die sich an einer Seite über die gesamte Breite des kurzen Schenkels erstreckt. Wie insbesondere aus der Fig. 1, der Fig. 3 und der Fig. 5 hervorgeht, sind in die Aufnahmekammer 3 zwei nutartig ausgebildete Zugänge 12 eingeformt. Die beiden nutartigen Zugänge 12 gehen vom Mundbereich 13 der Aufnahmekammer 3 aus und erstrecken sich entlang zweier gegenüberliegender Innenwandungen bis hin zu den beiden angeformten Rastabsätzen 7. Außerdem ist in das Gehäuse 1 ein vom Mundbereich 13 ausgehender, sich parallel zur Aufnahmekammer 3 erstreckender, bis in den Durchbruch 4 hineingeführter, nutartig ausgebildeter weiterer Zugang 14 eingeformt. Durch diese drei Zugänge 12,14 eröffnet sich die Möglichkeit, sowohl die Federarme 6 der Primärsicherung als auch den Verriegelungsarm 5 der Sekundärsicherung über ein einziges Werkzeug 15 einfach zu erreichen. Dies ist immer dann notwendig, wenn ein in seine Aufnahmekammer 3 eingebrachtes Steckkontaktelement 2 aus derselben wieder entnommen werden soll. Vor der Entnahme muß nämlich sowohl die Primär- als auch die Sekundärsicherung des Steckkontaktelementes 2 wieder aufgehoben werden.For the sake of simplicity, only a single receiving chamber 3 of the housing 1 is shown in the drawing. In order for effective secondary securing to result, the locking arm 5 is essentially L-shaped and comes with its short leg behind the securing lugs 10 molded onto the associated plug contact element. As can be seen in particular from FIG. 3, a reset slope 11 is formed in the short leg of the locking arm 5, which essentially represents an extension of the long leg in its contour and extends on one side over the entire width of the short leg. As can be seen in particular from FIG. 1, FIG. 3 and FIG. 5, two grooves 12 are formed in the receiving chamber 3. The two groove-like accesses 12 start from the mouth area 13 of the receiving chamber 3 and extend along two opposite inner walls to the two molded locking heels 7. In addition, a groove-shaped further access 14, which extends from the mouth area 13 and extends parallel to the receiving chamber 3 and leads into the opening 4, is formed in the housing 1. These three accesses 12, 14 open up the possibility of easily accessing both the spring arms 6 of the primary fuse and the locking arm 5 of the secondary fuse using a single tool 15. This is always necessary if a plug contact element 2 introduced into its receiving chamber 3 is to be removed from the same. Before removal, both the primary and the secondary fuse of the plug contact element 2 must be removed again.

Wie insbesondere aus der Fig. 4 hervorgeht, ist das Werkzeug 15 gabelförmig ausgebildet und weist drei Gabelzinken 16 auf. Zur Entnahme des Steckkontaktelementes 2 aus seiner Aufnahmekammer 3, wird das Werkzeug 15 mit seinen drei Gabelzinken 16 in das Gehäuse 1 eingeführt. Dabei werden zwei Gabelzinken 16 in die beiden nutartigen Zugängen 12 eingeführt und stellen letztendlich dadurch die beiden Federarme 6 des Steckkontaktelementes 2 zurück. Außerdem wird gleichzeitig ein Gabelzinken 16 in den weiteren Zugang 14 eingeführt und stellt letztendlich dadurch den Verriegelungsarm 5 aus seiner Verriegelungsposition in seine Entriegelungsposition zurück. Die Rückstellung des Verriegelungsarmes 5 wird dabei dadurch bewirkt, weil der in den nutartigen weiteren Zugang 14 eingeführte Gabelzinken 16 zunächst mit seinem freien Ende an der Rückstellschräge 11 zur Anlage kommt und beim weiteren Einführen des Werkzeuges 15 den Verriegelungsarm 5 über seine Rückstellschräge 11 mehr und mehr aus dem Querschnitt der Aufnahmekammer 3 herausdrückt. Letztendlich ist der Querschnitt der Aufnahmekammer 3 wieder vollkommen freigegeben, so daß das elektrische Steckkontaktelement 2 wegen des gleichzeitigen Aufhebens der Primär- und Sekundärsicherung schnell und einfach aus seiner Aufnahmekammer 3 entnommen werden kann.As can be seen in particular from FIG. 4, the tool 15 is fork-shaped and has three fork tines 16. To remove the plug contact element 2 from its receiving chamber 3, the tool 15 is inserted into the housing 1 with its three fork tines 16. Two fork tines 16 are inserted into the two groove-like accesses 12 and ultimately thereby reset the two spring arms 6 of the plug contact element 2. In addition, a fork tine 16 is simultaneously inserted into the further access 14 and ultimately thereby resets the locking arm 5 from its locking position to its unlocking position. The resetting of the locking arm 5 is brought about because the fork tines 16 inserted into the groove-like further access 14 initially come to rest with the free end against the reset slope 11 and when the tool 15 is inserted further the locking arm 5 via its reset slope 11 more and more from the cross section of the receiving chamber 3. Ultimately, the cross section of the receiving chamber 3 is completely released again, so that the electrical plug contact element 2 because of the simultaneous cancellation of the primary and Secondary fuse can be removed quickly and easily from its receiving chamber 3.

Um ein gleichzeitiges Aufheben der Primär- und Sekundärsicherung des elektrischen Steckkontaktelementes 2 zu gewährleisten, ist der dem nutartigen weiteren Zugang 14 zugeordnete Gabelzinken 16 etwas länger als die beiden übrigen Gabelzinken 16 ausgebildet.In order to ensure that the primary and secondary securing of the electrical plug-in contact element 2 is canceled at the same time, the fork tines 16 assigned to the groove-like further access 14 are designed somewhat longer than the two other fork tines 16.
