Abstract

The device is provided by 2 relatively spaced formations (10,14) in each of the inside corners of each of the 2 rectangular housing shells (2) forming the plug connector housing, between which corresponding sheet metal flanges of the contact insert are fitted, for cooperating with an electrically-conducting spring element (20), for fixing and contacting the contact insert.

Description

Die Erfindung betrifft eine Einrichtung zur Befestigung und federnder Kontaktierung eines Steckverbinderkontakteinsatzes mit mindestens einem Blechflansch in einem elektrisch leitenden Steckverbindergehäuse, das aus zwei verbindbaren, rechteckförmigen Halbschalen gebildet ist.The invention relates to a device for fastening and resilient contacting of a connector contact insert with at least one sheet metal flange in an electrically conductive connector housing, which is formed from two connectable, rectangular half-shells.

Eine derartige Einrichtung wird benötigt, um einen elektrisch leitenden Flansch, in dem ein Steckverbinderkontakteinsatz gehalten ist, werkzeuglos in einem Steckverbindergehäuse zu befestigen und eine elektrisch leitende Verbindung zwischen dem Flansch und dem Gehäuse zu gewährleisten und den VDE-Sicherheitsrichtlinien zu genügen.Such a device is needed to attach an electrically conductive flange in which a connector contact insert is held, tool-less in a connector housing and to ensure an electrically conductive connection between the flange and the housing and to comply with the VDE safety guidelines.

Aus ähnlich ausgeführten Steckverbindergehäusen ist bekannt, den in einem Blechflansch gehaltenen Steckverbinderkontakteinsatz mittels Schrauben in entsprechenden Schraubösen zu verschrauben, die in den Eckbereichen des Steckverbindergehäuses angeformt sind. Dazu sind jedoch stets Montagemaßnahmen auszuführen, die erst mit der Verschraubung des Steckverbinderkörpers abgeschlossen sind.From similar executed connector housings is known to screw the held in a sheet metal flange connector insert by means of screws in corresponding eyelets, which are integrally formed in the corner regions of the connector housing. For this purpose, however, always carry out installation measures that are completed only with the screw of the connector body.

In der EP-A-0 684 665 ist eine abgeschirmte Steckverbindereinheit, bestehend aus zwei elektrisch leitenden Gehäusehälften beschrieben, die in einem nichtleitenden Gehäuse angeordnet sind. Dabei ist das kontaktaufnehmende Steckerelement zumindest bereichsweise von einem elektrisch leitenden Flansch umgeben, der in einem Spalt in den innenliegenden Gehäusehälften einfügbar ist, um ein elektrisch abschirmsicheres Steckergehäuse auszubilden.In the EP-A-0 684 665 is a shielded connector unit, described consisting of two electrically conductive housing halves, which are arranged in a non-conductive housing. In this case, the contact-receiving plug element is at least partially surrounded by an electrically conductive flange which can be inserted in a gap in the inner housing halves in order to form an electrically shielding plug housing.

Weiterhin ist aus der US-A-4 544 227 ein abgeschirmter Steckverbinder bekannt, in dessen Steckbereich U-förmig und federnd geformte Abschirmbleche fixierbar sind, die ein zumindest bereichsweise an einem Gegenstecker vorgesehenes Abschirmblech kontaktieren.Furthermore, from the US-A-4 544 227 a shielded connector known in the plug-in area U-shaped and resiliently shaped shielding plates are fixed, which contact an at least partially provided on a mating connector shielding.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Art dahingehend auszubilden, dass in einem aus zwei Halbschalen gefertigten und miteinander verbindbaren Steckverbindergehäuse ein in einem Blechflansch gehaltener Steckverbinderkontakteinsatz ohne weiteres Befestigungsmittel in dem Steckverbindergehäuse fixierbar ist.The invention is therefore based on the object to form a device of the type mentioned in that in a made of two half-shells and connectable connector housing a held in a metal flange connector contact insert without further attachment means in the connector housing is fixed.

Diese Aufgabe wird dadurch gelöst, dass in den innenliegenden Eckbereichen der Halbschalen jeweils zwei beabstandete Anformungen vorgesehen sind, die einen Aufnahmeschlitz bilden, zwischen denen die Blechflansche einschiebbar sind, und dass zwischen den Anformungen in den Eckbereichen elektrisch leitende Federelemente mit Federarmen angeordnet sind, die auf die Kanten der Blechflansche einwirken, so dass der Steckverbinderkontakteinsatz nach dem Zusammenfügen der Halbschalen sicher fixiert ist.This object is achieved in that two spaced-apart projections are provided in the inner corner regions of the half-shells, which form a receiving slot between which the sheet metal flanges are inserted, and that between the projections in the corner regions electrically conductive spring elements are arranged with spring arms on the edges of the sheet metal flanges act, so that the connector contact insert is securely fixed after the joining of the half shells.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 7 angegeben.Advantageous embodiments of the invention are specified in claims 2-7.

Steckverbinder bestehen im Allgemeinen aus einem Steckverbindergehäuse an dem eine oder mehrere Kabeldurchführungen vorgesehen sind sowie aus mindestens einem Steckverbinderkontakteinsatz der in dem Gehäuse befestigt ist. Der Steckverbinderkontakteinsatz kann mit unterschiedlichen Befestigungsmethoden innerhalb des Gehäuses gehalten sein.
Eine Methode ist, an den Schmalseiten eines aus isolierendem Material gefertigten Steckverbinderkontakteinsatzes gewinkelte Blechflansche anzubringen, an deren Eckseiten vier unverlierbare Schrauben vorgesehen sind, mit denen der Steckverbinderkontakteinsatz an entsprechend angeformten Gewindeösen im Steckverbindergehäuse festgeschraubt wird.
Die mit der Erfindung erzielten Vorteile bestehen nun darin, dass derartige bekannte Steckverbinderkontakteinsätze ohne die Nutzung eines Werkzeuges in dem Steckverbindergehäuse fixierbar sind.
Dabei ist die erfindungsgemäße Einrichtung zunächst aus einfachen Anformungen gebildet, die aus der Wandung eines aus zwei Gehäusehälften gebildeten Steckverbindergehäuses hervorstehen sowie aus unterschiedlichen als Federelemente geformten Blechteilen.
Zwei jeweils voneinander beabstandete Anformungen bilden jeweils einen Aufnahmeschlitz, wobei in jedem Eckbereich des Steckverbindergehäuses ein Anformungspaar vorgesehen ist.Connectors generally consist of a connector housing on which one or more cable glands are provided and at least one connector contact insert which is mounted in the housing. The connector contact insert may be held with different attachment methods within the housing.
One method is to attach to the narrow sides of a manufactured from insulating material connector insert insert angled metal flanges on the corner sides of four captive screws are provided with which the connector contact insert is screwed to correspondingly molded eyelets in the connector housing.
The advantages achieved by the invention are now that such known connector contact inserts without the use of a tool in the connector housing can be fixed.
The device according to the invention is initially formed from simple projections which protrude from the wall of a connector housing formed from two housing halves and from different sheet metal parts formed as spring elements.
Two mutually spaced protrusions each form a receiving slot, wherein in each corner region of the connector housing, a mold pair is provided.

An bzw. zwischen diese Anformungen werden Federelemente fixiert, die als unterschiedlich geformte Blechteile teilweise verrastet und teilweise fest mit dem Gehäuse verbunden sind.
Die Halteelemente weisen mindestens ein Federelement auf, mit denen die Blechflansche, die in die Aufnahmeschlitze eingefügt sind, vorteilhafterweise gegen eine der Anformungen gedrückt werden und bei zusammengefügten Halbschalen sicher fixiert sind und gleichzeitig eine elektrische Kontaktierung zwischen dem Blechflansch und dem Gehäuse gewährleisten.
Dabei ist auch von Vorteil, dass Blechflansche mit zwei zwar definierten aber unterschiedlichen Blechstärken in die Aufnahmeschlitze eingefügt und fixiert werden können.
Bei einer Variante kann nur eine bestimmte Dicke eines Blechflansches von der Befestigungseinrichtung aufgenommen werden.At or between these projections spring elements are fixed, which are partially locked as differently shaped sheet metal parts and partially fixedly connected to the housing.
The holding elements have at least one spring element, with which the sheet metal flanges, which are inserted into the receiving slots, are advantageously pressed against one of the projections and are securely fixed in assembled half shells and at the same time ensure electrical contact between the sheet metal flange and the housing.
It is also advantageous that metal flanges can be inserted and fixed with two defined but different sheet thicknesses in the receiving slots.
In a variant, only a certain thickness of a sheet metal flange can be received by the fastening device.

Die Fig. 1 zeigt ein Steckverbindergehäuse 1, das im fertig montierten Zustand aus zwei Halbschalen gebildet ist und bei dem hier die vordere der Halbschalen entfernt ist.
In der hinteren Halbschale 2 ist ein Steckverbinderkontakteinsatz 6 gezeigt, der mittels gewinkelter Blechflansche 7 und der hier zu beschreibenden Einrichtung in dem Steckverbindergehäuse gehalten ist.Fig. 1 shows a connector housing 1, which is formed in the assembled state of two half-shells and in which here the front of the half-shells is removed.
In the rear half-shell 2, a connector contact insert 6 is shown, which is held by means of angled sheet metal flanges 7 and the device to be described here in the connector housing.

In der Fig. 2 ist in einer perspektivischen Darstellung lediglich die Halbschale 2 des Steckverbindergehäuses dargestellt, die drei Kabelzuführungen 3 aufweist.
In dem hier sichtbaren inneren Eckbereich 4 ist eine Einrichtung zur Befestigung des Steckverbinderkontakteinsatzes zu erkennen.
Die Vorrichtung wird gebildet aus zwei Anformungen 10, 14, die aus der Gehäusewand der Halbschale hervorragen sowie einem Federelement, das unterschiedliche Formen aufweisen kann.In Fig. 2, only the half-shell 2 of the connector housing is shown in a perspective view, the three cable feeders 3 has.
In the visible here inner corner region 4 is a device for fixing the connector contact insert can be seen.
The device is formed from two projections 10, 14, which protrude from the housing wall of the half-shell and a spring element, which may have different shapes.

Ein derartiges Federelement ist in der Fig. 3 in einem vergrößerten Maßstab gezeigt und besteht im Wesentlichen aus einem rahmenförmigen, um etwa 90° gewinkelten Blechteil 20, aus dem zwei in den Eckbereich weisende, dreiseitig freigestellte Federarme 24, 26 herausgeformt sind, deren Federenden 28 gewölbt sind.
An der Gehäuseschale 2 sind zwei Anformungen 10, 14 vorgesehen, auf die das Blechteil 20 aufschiebbar ist, so dass die Anformungen in die Ausnehmungen 23 zwischen dem Rahmen und den Federarmen eintauchen und letztlich daraus hervorstehen.
Ein hier nicht weiter beschriebener Verrastungsmechanismus 22 hält das Blechteil 20 an der Gehäuseschale 2 fest.
Durch die Beabstandung der Anformungen 10, 14 wird ein Schlitz 18 gebildet, in den der Blechflansch 7 des Steckverbinderkontakteinsatzes einschiebbar ist.Such a spring element is shown in Fig. 3 on an enlarged scale and consists essentially of a frame-shaped, bent by about 90 ° sheet metal part 20, from the two pointing in the corner region, three-sided release spring arms 24, 26 are formed, the spring ends 28th are arched.
On the housing shell 2, two projections 10, 14 are provided, on which the sheet metal part 20 can be pushed, so that the projections dive into the recesses 23 between the frame and the spring arms and ultimately protrude therefrom.
A not further described locking mechanism 22 holds the sheet metal part 20 to the housing shell 2 fixed.
By the spacing of the projections 10, 14, a slot 18 is formed, in which the sheet metal flange 7 of the connector contact insert is inserted.

Dabei ist die Breite des Schlitzes 18 in Zusammenwirken mit den Federarmen 24, 26 zur Aufnahme von zwei unterschiedlichen Blechdicken vorgesehen. Dazu sind die Federarme etwas versetzt, in unterschiedlichen Höhen im Rahmen des Blechteiles positioniert, so dass der hier links gezeigte Federarm 24 im oberen und der rechte Federarm 26 im unteren Bereich des rahmenförmigen Blechteiles 20 angeordnet ist.
Wird ein Blechflansch mit einer maximalen Dicke in den Schlitz 18 eingefügt, so werden die gewölbt ausgebildeten Federenden 28 der beiden Federelemente gegen die Blechflanschaußenkanten gedrückt.
Wird ein Blechflansch mit einer geringeren, jedoch spezifizierten Dicke in den Schlitz eingefügt, so schiebt sich der untere Federarm 26 unter den Blechflasch und presst diesen mit der Schmalseite gegen die obere Anformung 10, während der obere Federarm 24 mit seinem Federende gegen die Blechflanschaußenkante drückt. (Siehe dazu auch Fig. 8)The width of the slot 18 is provided in cooperation with the spring arms 24, 26 for receiving two different sheet thicknesses. For this purpose, the spring arms are slightly offset, positioned at different heights in the frame of the sheet metal part, so that the spring arm 24 shown on the left is arranged in the upper and the right spring arm 26 in the lower region of the frame-shaped sheet metal part 20.
If a metal flange is inserted with a maximum thickness in the slot 18, the curved trained spring ends 28 of the two spring elements are pressed against the sheet metal flange outer edges.
If a metal flange with a smaller, but specified thickness inserted into the slot, the lower spring arm 26 pushes under the sheet metal bottle and presses it with the narrow side against the upper Anformung 10, while the upper spring arm 24 presses with its spring end against the Blechflanschaußenkante. (See also Fig. 8)

Da an den Steckverbinderkontakteinsätzen Blechflansche montiert sind, die an den Außenecken Schrauben aufweisen, um die Blechflansche fest mit einem Steckverbindergehäuse zu verschrauben, ist die obere Anformung 10 mit einer Einbuchtung 12 versehen, in die eine derartige Schraube beim Einfügen des Blechflansches in den Aufnahmeschlitz 18 lediglich hineinragt.
Die hier untere Anformung 14 ist kleiner und gegenüber der oberen Anformung mit einem verrundeter Vorsprung 16 ausgebildet.
Beim abschließenden Verschrauben der beiden Halbschalen ist der Steckverbinderkontakteinsatz fest in den Vorrichtungen im Steckverbindergehäuse gehalten.Since sheet metal flanges are mounted on the connector contact inserts, which have screws on the outer corners to screw the sheet metal flanges fixed to a connector housing, the upper Anformung 10 is provided with a recess 12 into which such a screw when inserting the sheet metal flange in the receiving slot 18 only protrudes.
The lower Anformung 14 here is smaller and opposite the upper Anformung formed with a rounded projection 16.
During the final screwing of the two half-shells, the connector contact insert is held firmly in the devices in the connector housing.

In der Fig. 4 ist eine Variante zu dem in der Fig. 3 dargestellten Federelement gezeigt, bei dem ein ebenfalls über Eck gebogenes Blechteil 30 vorgesehen ist, bei dem die Federarme 34, 36 an den Außenkanten der beiden Blechschenkel angeordnet sind, und zwar so, dass sie wie in der Fig. gezeigt, senkrecht aus dem Blechmaterial freigestellt sind.
Die Federenden 38 sind leicht gewölbt geformt, in den Innenraum der Halbschale wirkend.FIG. 4 shows a variant of the spring element shown in FIG. 3, in which a metal sheet part 30, which is likewise curved over the corner, is provided, in which the spring arms 34, 36 are arranged on the outer edges of the two sheet metal limbs, to be precise in that they are exposed vertically from the sheet material as shown in the figure.
The spring ends 38 are slightly curved, acting in the interior of the half-shell.

Das Blechteil 30 wird ebenfalls auf etwas abgewandelte Anformungen 10', 14' an der Gehäusewand der Halbschale aufgeschoben und dort fixiert.The sheet metal part 30 is also pushed onto slightly modified projections 10 ', 14' on the housing wall of the half-shell and fixed there.

In der Fig. 5 ist eine weitere Variante eines Federelementes gezeigt, das als winkelförmiges Blechteil 40 einen Befestigungsabschnitt 42 und einen abgewinkelten Federarm 44 mit einem gewölbten Federende 48 aufweist.
Das Blechteil wird anstelle der hier teilweise gekürzten, unteren Anformung 14 unterhalb der Anformung 10 an der Gehäusewand der Halbschale befestigt, so dass das gewölbte Federende 48 gegen die Anformung 10 gerichtet ist und bei einem dazwischen liegenden Blechflansch diesen gegen die Anformung drückt.
Diese Variante erlaubt jedoch nur das Einfügen eines Blechflansches mit einer spezifizierten Dicke.5, a further variant of a spring element is shown, which has an attachment portion 42 and an angled spring arm 44 with a curved spring end 48 as an angle-shaped sheet metal part.
The sheet metal part is fixed instead of here partially shortened, lower Anformung 14 below the Anformung 10 on the housing wall of the half-shell, so that the curved spring end 48 is directed against the Anformung 10 and presses against the Anformung at an intermediate sheet metal flange.
However, this variant only allows the insertion of a sheet metal flange with a specified thickness.

Die Fig. 6 zeigt ein als flaches Blechteil 50 ausgeführtes Federelement, das einen Befestigungsabschnitt 52 und einen Federarm 54 mit einem gewölbten Federende 58 aufweist.
Das Blechteil 50 ist mit seinem freigestellten Federarm in dem Aufnahmeschlitz 18 zwischen den beiden Anformungen 10, 14 positioniert, so dass die Federwirkung auf die Flanschaußenkante eines im Aufnahmeschlitz eingefügten Blechflansches gerichtet ist.
An dem Befestigungsabschnitt 52 ist das Blechteil 50 an der Gehäusewandung befestigt.
Diese Variante erlaubt jedoch nur das Einfügen eines Blechflansches mit einer spezifizierten Dicke.FIG. 6 shows a spring element designed as a flat sheet-metal part 50, which has a fastening section 52 and a spring arm 54 with a curved spring end 58.
The sheet metal part 50 is positioned with its exempt spring arm in the receiving slot 18 between the two projections 10, 14, so that the spring action is directed to the flange outer edge of a sheet metal flange inserted in the receiving slot.
At the attachment portion 52, the sheet metal part 50 is attached to the housing wall.
However, this variant only allows the insertion of a sheet metal flange with a specified thickness.

Die Fig. 7 zeigt ebenfalls ein als flaches Blechteil 60 geformtes Federelement. Durch den langen Federweg der sich an den Befestigungsabschnitt 62 anschließenden Federarme 64, 66 mit den gewölbten Federenden 68 ist ein relativ weiches Einsetzen eines Blechflansches möglich.
Das Blechteil 60 wird in eine Ausnehmung 5 in der Gehäusewandung eingefügt und mittels einer Nietbefestigung fixiert, so dass die Wölbung der Federenden 68 in den Innenraum weist. Diese doppelte Anordnung der Federarme erlaubt wiederum den Einsatz von zwei unterschiedlichen Blechstärken eines Blechflansches in den Aufnahmeschlitz 18, wie bereits in Fig. 3 beschrieben.Fig. 7 also shows a shaped as a flat sheet metal part 60 spring element. Due to the long spring travel of adjoining the attachment portion 62 spring arms 64, 66 with the curved spring ends 68, a relatively soft insertion of a sheet metal flange is possible.
The sheet metal part 60 is inserted into a recess 5 in the housing wall and fixed by means of a rivet fastening, so that the curvature of the spring ends 68 points into the interior. This double arrangement of the spring arms in turn allows the use of two different sheet thicknesses of a sheet metal flange in the receiving slot 18, as already described in Fig. 3.

In der Fig. 8 ist in einer Ansicht des Eckbereiches 4 der Halbschale 2 aus der Fig. 7 eine Befestigungseinrichtung mit einem montierter Blechflansch 7 gezeigt, um die Funktionsweise der Einrichtung zu erläutern.
Dabei ist ein dünner Blechflansch 7 mit einer Befestigungsschraube 8 in den Aufnahmeschlitz 18 zwischen den beiden Anformungen 10, 14 eingefügt. Der Blechflansch berührt die Unterkante der oberen Anformung 10, wobei ein Abstand zur unteren Anformung 14 bleibt.
Diesen Abstand bewirkt der untere Federarm 66, der unterhalb des Blechflansches positioniert ist, während der obere Federarm 64 von der Blechflanschkante in die Ausnehmung 5 gedrückt wird. Somit erfolgt eine werkzeuglose Montage und Fixierung des Blechflansches im Steckergehäuse bei gleichzeitiger elektrischer Kontaktierung.
Wird ein Blechflansch mit einer den Aufnahmeschlitz 18 ausfüllenden Blechdicke eingesetzt, so werden beide Federarme64, 66 in die Ausnehmung 5 gedrückt und beide Federarme drücken mit den gewölbten Federenden 68 gegen die Blechflanschkante.FIG. 8 shows, in a view of the corner region 4 of the half-shell 2 from FIG. 7, a fastening device with a mounted sheet-metal flange 7 in order to explain the functioning of the device.
In this case, a thin sheet metal flange 7 is inserted with a fastening screw 8 in the receiving slot 18 between the two projections 10, 14. The sheet metal flange touches the lower edge of the upper Anformung 10, wherein a distance to the lower Anformung 14 remains.
This distance causes the lower spring arm 66, which is positioned below the sheet metal flange, while the upper spring arm 64 is pressed by the Blechflanschkante in the recess 5. Thus, there is a tool-free installation and fixation of the sheet metal flange in the connector housing with simultaneous electrical contact.
If a sheet metal flange with a receiving slot 18 filling sheet metal thickness is used, both spring arms64, 66 are pressed into the recess 5 and push both spring arms with the curved spring ends 68 against the sheet metal flange.
