Description

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

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 connector parts are in particular intended to go over their to electrical wires connected plug contact elements a releasable electrical connection to a mating connector part create. The mating connector part can e.g. also be connected to an electrical line or are 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.DE 43 01 602 C1 is the generic term of Main claim corresponding electrical Connector part became known. With this electrical Plug connection part are the electrical Plug contact elements in the receiving chambers of the housing introduced, which for each chamber with a Locking arm is provided. The so-called secondary Each locking arm can be secured by one Unlocked position brought into a locking position become. In addition, the electrical Plug-in contact elements each formed two spring arms, which behind molded onto walls of the associated receiving chamber Resting paragraphs come to rest, so that in the Electrical plug contact elements located in the receiving chambers are primarily secured. Should be an electric one Removed connector element from its receiving chamber a tool is inserted into the associated receptacle introduced, which the Primary lock is released. To the plug contact element to be able to remove from his reception chamber, however, must still through a further step the Secondary lock can be released.

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, DE 41 24 541 A1 is an electrical one Plug connector became known, in the Storage chambers for locking inserted Plug contact elements elastically deflectable locking arms available. The locking arms are on a housing wall molded and arrive for locking with their free end a projection of the associated plug contact elements to lie. To achieve a secure locking, from the mating side a spacer block in the interior of the Inserted connector part, which in a first Position an elastic deflection of the locking arms allows and which in a second position The locking arms can be deflected. Should now Removed plug contact element from its receiving chamber the distance block must first be returned to its first Position can only be used to deflect the Locking arm a tool in the interior of the Inserted connector part and the relevant Removed plug contact element from its receiving chamber become. Because of completely missing housing and Measures on the plug contact element side is possible by means of a such connector part, however, only one Locking measure for the plug contact elements realizable. To cancel this, just click on one Locking measure related locking are however several 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 present invention has the object based on an electrical connector part such to further develop that through a single step both the primary as well as the secondary locking only is canceled by inserting a single tool and thus a quick, easy 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 task with an electrical Connector part of the type mentioned by the in characteristic part of the main claim specified features solved.

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.Particularly advantageous when using such electrical connector parts is that despite one particularly secure locking by two Interlocking measures a quick and easy Removal of electrical plug contact elements cost-effective way is realized.

Wie aus der Zeichnung hervorgeht, besteht ein solches elektrisches Steckverbindungsteil hauptsächlich aus einem aus Kunststoff hergestellten 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, there is one electrical connector mainly from one Plastic-made housing 1 in the at least one for Inclusion of an associated electrical plug contact element 2 provided receiving chamber 3 is present. In at least an outer housing wall of the housing 1 is located Receiving chamber 3 an opening 4 with one therein arranged, on the one hand in one piece to this outer Lock arm 5 molded onto the 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 located in the receiving chambers 3 of the housing 1 electrical plug contact elements 2 must be secured in the same, so that after connecting the Connector part with its mating connector part whose functionality is guaranteed. Each For this purpose, plug contact element 2 has two molded spring arms 6 on, each behind one on the walls of the associated Receiving chambers 3 molded locking paragraph 7 come to rest. Place the two spring arms 6 and the two locking shoulders 7 regarding the necessary position securing of the electrical Plug contact element 2 represents the so-called primary fuse. In addition, each electrical plug contact element 2 for Position securing additionally between one to the Molded mouth area 13 of the associated receiving chamber 3 End stop 8 and in its locking position brought locking arm 5 held secured. Doing so the one with the free end to the electrical Plug contact element 2 locking arm 5 coming into contact for the so-called secondary fuse. Any locking arm 5 is movable via a film hinge 9 to an outer one Molded housing wall of the housing 1. In single row Plug connection parts are all locking arms 5 Part of a single outer housing wall, whereas the locking arms 5 Components of two opposite outer housing walls of the housing 1 are.

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 den an das zugeordnete Steckkontaktelement angeformten Sicherungsansätzen 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, there is only one in the drawing Receiving chamber 3 of the housing 1 shown. So that one effective secondary backup is the Locking arm 5 is substantially L-shaped and comes with its short leg behind the assigned Plug contact element molded fuse lugs 10 to lie. As can be seen in particular from FIG. 3, the short Leg of the locking arm 5 a reset slope 11 molded, which is essentially a contour Extension of the long leg represents and the itself one side across the entire width of the short leg extends. As in particular from FIG. 1, FIG. 3 and 5 shows are two groove-like in the receiving chamber 3 trained entrances 12 molded. The two groove-like Accesses 12 start from the mouth area 13 of the receiving chamber 3 and extend along two opposite Inner walls up to the two molded locking heels 7. In addition, the housing 1 has a mouth area 13 outgoing, extending parallel to the receiving chamber 3, up to the opening 4, groove-like trained further access 14 molded. Through these three Accesses 12, 14 opens up the possibility of both the Spring arms 6 of the primary fuse and the locking arm 5 the secondary fuse using a single tool 15 simple to reach. This is always necessary when one is in his Receiving chamber 3 introduced plug contact element 2 the same should be removed again. Before removal namely both the primary and the secondary backup of the Plug contact element 2 are canceled 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 fork-shaped and has three fork tines 16. To remove the plug contact element 2 from it Receiving chamber 3, the tool 15 with its three Forks 16 inserted into the housing 1. This will be two Forks 16 are inserted into the two groove-like accesses 12 and ultimately put the two spring arms 6 of the Plug contact element 2 back. It also becomes a Forks 16 inserted in the further access 14 and provides ultimately the locking arm 5 from it Lock position back to its unlock position. The provision of the locking arm 5 is thereby causes because of the groove-like further access 14th introduced fork tines 16 first with its free end the reset slope 11 comes to rest and the rest Inserting the tool 15 the locking arm 5 via its Reset slope 11 more and more from the cross section of the Presses out chamber 3. Ultimately it is Cross section of the receiving chamber 3 again completely released so that the electrical plug contact element 2 because of the simultaneous cancellation of the primary and Secondary backup quickly and easily from his Receiving chamber 3 can be removed.

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.To simultaneously cancel the primary and Secondary fuse of the electrical plug contact element 2 too ensure that is the groove-like further access 14th assigned fork tines 16 somewhat longer than the other two Forks 16 formed.
