Description

Die Erfindung betrifft eine Verriegelung für eine lösbare Steckverbindung nach dem Oberbegriff des Anspruchs 1.The invention relates to a lock for a releasable connector according to the preamble of claim 1.

Eine derartige Verriegelung wird benötigt, um eine aus einem Steckverbinder und einem Gegenstecker gebildete, lösbare Steckverbindung miteinander zu verbinden und mittels eines einfach ausgebildeten Mechanismus wieder voneinander zu lösen.Such a lock is required to connect a formed of a connector and a mating connector, releasable connector with each other and to solve by means of a simple mechanism again from each other.

Die US5435744 zeigt eine Verriegelung für eine lösbare Steckverbindung. Hier wird ein Steckereinsatz von einer verschiebbaren zweiteiligen Hülse umgeben. Am Steckereinsatz sind beidseitig Metallfinger angeformt, die wiederum Rasthaken aufweisen, die nach außen gerichtet sind. Die nach außen gerichteten Rasthaken greifen zur lösbaren Verbindung an einen Gegenstecker an.The US5435744 shows a lock for a releasable connector. Here is a plug insert surrounded by a sliding two-piece sleeve. On the plug insert metal fingers are formed on both sides, which in turn have latching hooks which are directed to the outside. The outwardly directed latching hooks engage the releasable connection to a mating connector.

Die EPO 738 029 A1 zeigt einen Stecker mit Metallfingern, die nach innen gerichtete Rasthaken aufweisen. Um einen Gegenstecker zu arretieren, greifen die Rasthaken hinter Rastnasen ein, die nach außen gerichtet am Gegenstecker angeformt sind.The EPO 738 029 A1 shows a plug with metal fingers, which have inwardly directed latching hooks. In order to lock a mating connector, engage the locking hooks behind locking lugs, which are formed on the mating connector directed outwards.

Aus der DE 102 36 275 B3 ist eine Verriegelungseinrichtung bekannt, bei der eine Schiebehülse auf einem Steckgehäuse angeordnet ist, das angeformte Rastmittel aufweist, die in Rastausnehmungen eines Gegensteckers eintauchen und durch Verschieben der Schiebehülse entriegelbar sind.From the DE 102 36 275 B3 a locking device is known in which a sliding sleeve is arranged on a plug housing which has integrally formed locking means, which dive into latching recesses of a mating connector and can be unlocked by moving the sliding sleeve.

Die US 5 634 809 zeigt einen Steckverbinder dessen äußeres Gehäuse eine Ausnehmung aufweist, in welcher eine Schiebeplatte eingelegt ist, die wiederum mit einem Gleitstab wirkverbunden ist. Am Gleitstab sind Rasthaken angeformt, die aus Rastöffnungen eines Gegensteckers herausgeführt werden, wenn die Schiebeplatte entgegen der Steckrichtung bewegt wird.The US 5,634,809 shows a connector whose outer housing has a recess in which a sliding plate is inserted, which in turn is operatively connected to a sliding rod. On sliding rod locking hooks are formed, which are led out of locking openings of a mating connector when the sliding plate is moved counter to the direction of insertion.

Derartige, bekannte Steckverbindungen sind häufig aus Kunststoffteilen gefertigt und sind dadurch nicht für hohe Steckzyklen vorgesehen, und weisen auch relativ geringe Verriegelungs-Haltekräfte auf, die keine sichere Verriegelung bieten.Such known connectors are often made of plastic parts and are therefore not intended for high mating cycles, and also have relatively low locking holding forces that provide no secure locking.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Steckverbinderverriegelung der eingangs genannten Art dahingehend auszubilden, dass ein störstrahlsicheres, rechteckig geformtes Steckgehäuse mittels einer Schiebemechanik mit einem Gegenstecker verriegelbar ist, der hohe mechanische Verrastungskräfte und hohe Steckzyklen aufweist.The invention is therefore the object of a connector lock of the type mentioned in such a way that a störstrahlsicheres, rectangular shaped plug housing by means of a sliding mechanism Lockable with a mating connector, which has high mechanical latching forces and high mating cycles.

Diese Aufgabe wird durch die kennzeichnenden Merkamle des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 - 13 angegeben.Advantageous embodiments of the invention are specified in claims 2-13.

Steckverbindungen dieser Art sind für eine hohe Verschleißfestigkeit ausgelegt und weisen aufgrund einer metallischen Hülle einen hohen EMV-Schutz auf.
Die Verriegelung der Steckverbindung ist vorteilhafterweise mit einer Schiebetechnik ausgestattet, die ein einfaches Ver- und Endriegeln der Steckverbindung gestattet.
Dabei ist eine Erzielung von etwa 5000 Steckzyklen, sowie hoher Verriegelungs-Haltekräfte von 200 N vorteilhafterweise nur mit metallischen Bauteilen zu erreichen. Zudem ist bei metallischen Bauteilen gleichzeitig ein deutlich vernehmbares Klicken beim Verrasten der Steckverbindung zu erzielen.Plug connections of this type are designed for high wear resistance and have a high EMC protection due to a metallic shell.
The locking of the connector is advantageously equipped with a sliding technology that allows a simple locking and Endriegeln the connector.
It is an achievement of about 5000 mating cycles, and high locking holding forces of 200 N advantageously only to achieve with metallic components. In addition, at the same time a clearly audible click when locking the connector to achieve metallic components.

Der aus einem Metallgehäuse mit einem darin angeordneten Steckereinsatz und einer Endkappe gebildete Stecker ist von einer aus isolierendem Material gefertigten verschiebbaren Hülse umgeben.
Dabei besteht das Metallgehäuse aus miteinander verrasteten Teilen eines Basisgehäuses und eines Abdeckteiles.
Vorteilhafterweise ist die Hülse um einen bestimmten Weg verschiebbar und unverlierbar auf dem Metallgehäuse angeordnet.
Mittels der verschiebbaren Hülse werden zwei am Metallgehäuse angeformte Metallfinger auseinanderbewegt, so dass daran vorgesehene Rasthaken bei einer verriegelten Steckverbindung vorteilhafterweise aus Rastöffnungen an einem Gegenstecker herausgehebelt werden.
Dazu sind die Metallfinger in Schlitzen geführt, die im Inneren der Hülse in den Seitenflächen eingeformt sind. Vorteilhafterweise sind die Schlitze in einem von der Steckrichtung abweichenden Winkel angeordnet, so dass bei einer translatorischen Bewegung der Hülse eine seitlich ausweichende Bewegung der Rasthaken an den Metallfingerenden erzielbar ist, wodurch das Aushebeln aus den Rastöffnungen im Gegenstecker gewährleistet ist.The formed of a metal housing with a plug insert disposed therein and an end cap plug is surrounded by a made of insulating material displaceable sleeve.
In this case, the metal housing consists of latched together parts of a base housing and a cover.
Advantageously, the sleeve is displaceable by a certain distance and arranged captive on the metal housing.
By means of the displaceable sleeve, two metal fingers formed on the metal housing are moved apart so that latching hooks provided thereon be advantageously levered out of locking openings on a mating connector at a locked connector.
For this purpose, the metal fingers are guided in slots which are formed in the interior of the sleeve in the side surfaces. Advantageously, the slots are arranged in a different direction from the plug-in angle, so that in a translational movement of the sleeve, a laterally evasive movement of the latching hooks on the metal finger ends can be achieved, whereby the levering is ensured from the latching openings in the mating connector.

Die hier beschriebene Steckverbindung ist zunächst für eine Kabelverbindung mit einem Leiterplattensteckverbinder vorgesehen, der ebenfalls mittels einer metallischen Haube gegen Störeinstrahlung geschützt ist.
Dieser Leiterplattenstecker ist jedoch leicht gegen einen Kabelsteckverbinder austauschbar, so dass auch eine reine Kabelsteckverbindung realisierbar ist.The connector described here is initially provided for a cable connection with a printed circuit board connector, which is also protected by a metallic hood against interference.
However, this PCB connector is easily interchangeable with a cable connector, so that a pure cable connector is feasible.

In der Fig.1 ist in einer auseinandergezogenen Darstellung ein Stecker 1 gezeigt, der aus einem Basisgehäuse 10 und einem Abdeckteil 20 besteht, die zusammengefügt ein Metallgehäuse 5 bilden. In diesem Metallgehäuse 5, umgeben von einer aus isolierendem Material bestehenden, verschiebbaren Hülse 40, ist ein Steckereinsatz 50 angeordnet, der mit einem elektrischen Kabel 3 kontaktierbar ist. Zur Zuführung und Halterung des elektrischen Kabels 3 ist eine Endkappe 30 mit einem Knickschutz 32 aus flexiblem isolierenden Material vorgesehen, die formschlüssig auf das Metallgehäuse 5 aufzuschieben ist.In the Fig.1 is shown in an exploded view of a plug 1, which consists of a base housing 10 and a cover 20, which together form a metal housing 5. In this metal housing 5, surrounded by a sliding sleeve 40 made of insulating material, a plug insert 50 is arranged, which can be contacted with an electrical cable 3. For feeding and holding the electric cable 3, an end cap 30 is provided with a kink protection 32 made of flexible insulating material, which is to be pushed onto the metal housing 5 in a form-fitting manner.

Das in Fig. 2 gezeigte Basisgehäuse 10 ist als rechteckig geformte Hülse mit einer Bodenfläche 11, einer Deckfläche 12 und zwei schmalen Seitenflächen 13 versehen, wobei die Deckfläche 12 kürzer als die entgegengesetzt angeordnete Bodenfläche 11 ausgeführt ist. In die so gebildete Öffnung wird der Steckereinsatz 50 in das Basisgehäuse eingefügt.
Bei korrekt eingesetztem und verrastetem Steckereinsatz 50 in das Basisgehäuse 10 ist die Steckseite 51 innerhalb des Metallgehäuses 5 und der Hülse 40 gehalten, während die Anschlussseite 52 noch innerhalb der Deckfläche 12 angeordnet ist.
Der Steckereinsatz 50 ist aus isolierendem Material geformt, wobei die Steckseite 51 Buchsenkontakte 53 aufweist, die aufgeteilt in Signaldaten- und Stromversorgung in unterschiedlich geformten Öffnungen 54 im Steckereinsatz eingefügt sind. (Siehe Fig. 3)
Weiterhin ist ersichtlich, dass das Basisgehäuse 10 vorzugsweise für die abschirmende Wirkung zwischen der Kabelabschirmung 4 und der Steckseite vorgesehen ist, während das Abdeckteil 20 vorzugsweise für die Übertragung der mechanischen Haltekräfte angepasst ist. Dabei können unterschiedliche Materiealien zur Anwendung vorgesehen sein.
Auf den offenen, frei zugänglichen Bereich des Basisgehäuses 10, in Richtung des elektrischen Kabels 3, hinter der Deckfläche 12 wird das Abdeckteil 20 aufgesetzt und verrastet.
Das Abdeckteil 20 ist im wesentlichen U-förmig gebogen, mit einer Deckfläche 21, zwei schmalen Seitenflächen 23 und mit zwei abgewinkelten Rückwänden 22, die einen Abschluss zur Kabelanschlussseite bilden, wobei ein mittlerer Bereich für das zum Steckereinsatz 50 hindurchzuführende elektrische Kabel 3 frei bleibt.
In Steckrichtung weisend, sind an den Seitenflächen 23 des Abdeckteiles 20 Metallfinger 27 angeformt, an deren Enden Rasthaken 28 vorgesehen sind sowie unter einem flachen Winkel nach außen gebogene, verrundete Enden 29.
Das Abdeckteil 20 sowie das Basisgehäuse 10 weisen als Rastnasen und Rastöffnungen ausgebildete Rastmittel 24, 14 auf, mittels derer die beiden Gehäuseteile verrastbar sind.
Weiterhin ist in dem Abdeckteil 20 in Steckrichtung eine Haltevorrichtung 26 mit einer dreiseitig freistehenden Rastklinke 26' für die Halterung der Hülse 40 auf dem Metallgehäuse 5 vorgesehen, so dass die Hülse um einen bestimmten Weg verschiebbar aber unverlierbar auf der Metallgehäuse 5 gehalten ist.
An dem Metallgehäuse 5 sind zur Anschlussseite weisende Zungen 15, 25 vorgesehen, wobei die am Abdeckteil angeformte Zunge 25 oberhalb der am Basisgehäuse angeformten Zunge 15 angeordnet ist.
Zwischen diesen Zungen wird das elektrische Kabel 3 nach der Montage mit hier nicht gezeigten Einzelleiter mit den Kontakten im Steckereinsatz mit seiner Abschirmgeflecht 4 positioniert. Anschließend wird ein bereits auf dem elektrischen Kabel 3 aufgezogener Ring 70 über die beiden Zungen 15, 25 geschoben und diese Anordnung mittels einer Crimpzange vercrimpt.This in Fig. 2 shown base housing 10 is provided as a rectangular shaped sleeve having a bottom surface 11, a top surface 12 and two narrow side surfaces 13, wherein the top surface 12 is shorter than the oppositely disposed bottom surface 11 is executed. In the opening thus formed, the plug insert 50 is inserted into the base housing.
When correctly inserted and latched connector insert 50 into the base housing 10, the mating side 51 is held within the metal housing 5 and the sleeve 40, while the connection side 52 is still disposed within the top surface 12.
The plug insert 50 is formed of insulating material, wherein the plug side 51 socket contacts 53, which are divided into signal data and power supply in different shaped openings 54 inserted in the plug insert. (Please refer Fig. 3 )
Furthermore, it can be seen that the base housing 10 is preferably provided for the shielding effect between the cable shield 4 and the mating side, while the cover member 20 is preferably adapted for the transmission of the mechanical holding forces. Different materials may be provided for use.
On the open, freely accessible area of the base housing 10, in the direction of the electric cable 3, behind the top surface 12, the cover 20 is placed and locked.
The cover member 20 is bent substantially U-shaped, with a top surface 21, two narrow side surfaces 23 and two angled rear walls 22, which form a termination to the cable connection side, wherein a central region for the electrical insert 3 to be passed to the plug insert 50 remains free.
Pointing in the insertion direction, 20 metal fingers 27 are integrally formed on the side surfaces 23 of the cover, at the ends of latching hooks 28 are provided and at a shallow angle outwardly curved, rounded ends 29th
The cover 20 and the base housing 10 have latching lugs and detent openings formed locking means 24, 14, by means of which the two housing parts can be latched.
Furthermore, in the cover 20 in the insertion direction, a holding device 26 is provided with a three-sided free-standing latch 26 'for holding the sleeve 40 on the metal housing 5, so that the sleeve is slidably held by a certain way but captive on the metal housing 5.
On the metal housing 5 facing tongues 15, 25 are provided, wherein the molded on the cover member tongue 25 is disposed above the integrally formed on the base housing tongue 15.
Between these tongues, the electrical cable 3 is positioned after assembly with individual conductors, not shown here, with the contacts in the plug insert with its shielding braid 4. Subsequently, a ring 70 already mounted on the electric cable 3 is pushed over the two tongues 15, 25 and this arrangement is crimped by means of a crimping tool.

ln der Fig. 4 ist das aus den beiden Teilen Basisgehäuse 10 und Abdeckteil 20 zusammengefügte Metallgehäuse 5 mit Sicht auf die Anschlussseite mit dem elektrischen Kabel 3 und dem noch zu vercrimpenden Ring 70 ersichtlich. Dabei ist auch der leicht von der Seitenwand des Basisgehäuses 10 abstehende Metallfinger 27 den abgewinkelten Rasthaken 28 erkennbar.ln the Fig. 4 is the assembled from the two parts of the base housing 10 and cover 20 metal housing 5 with a view of the connection side with the electrical cable 3 and the still to be crimped ring 70 can be seen. In this case, the slightly projecting from the side wall of the base housing 10 metal finger 27 is the angled latching hook 28 recognizable.

Die bereits in der Fig. 1 gezeigte Hülse 40 ist passend zu dem Metallgehäuse 5 rechteckig geformt, wobei die schmalen Seitenflächen 42 von der Steckseite gesehen eine bereichsweise dickere Wandung aufweisen als die beiden Deckflächen 41.
In der Fig. 5a und 5b ist dazu ein Ausschnitt dargestellt, der auch die weitere Funktion der Verriegelung aufzeigt.
Innerhalb dieser zumindest bereichsweise dickeren Wandung der Seitenfläche 42 ist eine entgegen der Steckrichtung weisende, keilförmige Zunge 43 angeformt, die durch einen Schlitz 45 von der Seitenfläche 42 getrennt ist. Auf der keilförmigen Zunge 43 ist eine Gleitfläche 44 vorgesehen auf der das Ende 29 des Metallfingers 27 entlang gleiten kann, wobei die Zunge 43 derartig ausgebildet ist, dass sie zwischen den beidseitig am Ende des Metallfingers 27 angeformten Rasthaken 28 angeordnet ist.The already in the Fig. 1 shown sleeve 40 is shaped to match the metal housing 5 rectangular, with the narrow side surfaces 42 of the Plug side seen a partially thicker wall than the two top surfaces 41st
In the Fig. 5a and 5b For this purpose, a section is shown, which also shows the further function of the lock.
Within this at least partially thicker wall of the side surface 42 a opposite to the insertion direction facing, wedge-shaped tongue 43 is formed, which is separated by a slot 45 of the side surface 42. On the wedge-shaped tongue 43, a sliding surface 44 is provided on which the end 29 of the metal finger 27 can slide along, wherein the tongue 43 is formed such that it is arranged between the both sides of the end of the metal finger 27 integrally formed latching hooks 28.

Beim Aufschieben der Hülse 40 auf das Metallgehäuse 5 und wie in den Fig. 5a und 5b ersichtlich, werden die Metallfinger 27 zwangsweise, mit einer nach Außen wirkenden Vorspannung, in die Schlitze 45 eingeschoben.
Dazu ist das Ende 29 des Metallfingers, unmittelbar anschließend an die doppelt ausgeführten Rasthaken 28, leicht auswärts gebogen, so dass das Ende 29 in die schräg zur Gehäuseachse verlaufenden Schlitze 45 einfädelbar ist.
Je weiter die Hülse nach hinten - entgegen der Steckrichtung - geschoben wird, desto weiter werden die Metallfinger auseinandergezogen.
Dabei ist vorgesehen, dass der Öffnungswinkel in dem der Metallfinger von der Seitenwand absteht im Ruhezustand etwa 25° beträgt, während zur Entriegelung etwa 30° erforderlich sind.When sliding the sleeve 40 on the metal housing 5 and as in the Fig. 5a and 5b As can be seen, the metal fingers 27 are forcibly inserted into the slots 45 with an outwardly acting bias.
For this purpose, the end 29 of the metal finger, immediately following the double-executed locking hooks 28, slightly bent outwards, so that the end 29 is in the obliquely to the housing axis extending slots 45 can be threaded.
The further the sleeve is pushed backwards - contrary to the direction of insertion - the further the metal fingers are pulled apart.
It is provided that the opening angle in which the metal finger protrudes from the side wall in the idle state is about 25 °, while the unlocking about 30 ° are required.

Die Fig. 5a zeigt den "Ruhezustand" an, in dem der Stecker 1 in der Ruheposition, bzw. hier beim gesteckten Zustand mit einem Gegenstecker 60, in einer "Verriegelungsposition" dargestellt ist. Dabei haken die Rasthaken 28 aus dem Stecker 1 in Rastöffnungen 67 des Gegensteckers 60 hinein und verhindert ein ungewolltes Lösen der Steckverbindung.The Fig. 5a indicates the "idle state" in which the plug 1 in the rest position, or here in the inserted state with a mating connector 60, in a "locking position" is shown. In this case hook the latch hooks 28 from the plug 1 in latching openings 67 of the mating connector 60 and prevents accidental release of the connector.

Die Fig. 5b zeigt den Stecker 1 mit zurückgezogener Hülse 40 in einer "Entriegelungsposition", wobei das Metallgehäuse etwa 2 mm aus der Hülse herausragt und gleichzeitig das Ende 29 des Metallfingers 27 weit in den Schlitz 45 hineinragt und die Rasthaken 28 bereits aus den Rastöffnungen 67 herausgeführt sind, so dass die Steckverbindung gelöst werden kann. (Siehe dazu auch Fig. 7)The Fig. 5b shows the plug 1 with retracted sleeve 40 in an "unlocked" position, wherein the metal housing protrudes about 2 mm from the sleeve and at the same time the end 29 of the metal finger 27 projects far into the slot 45 and the latching hooks 28 are already led out of the latching openings 67, so that the connector can be solved. (See also Fig. 7 )

Die Fig. 6 zeigt einen zur Montage auf einer Leiterplatte 7 vorbereiteten Gegenstecker 60 in einer auseinandergezogenen Darstellung.
Der Gegenstecker 60 wird aus einer Metallhülse 65, einem Steckereinsatz 61 und einer Metallhaube 64 gebildet.
Die Metallhülse weist zwei Montagearme 66 auf mit jeweils einem abgewinkelten Ende auf, mittels dem eine Masseanbindung mit der Leiterplatte 7 ermöglicht wird.
Weiterhin sind in den Montagearmen 66 Rastöffnungen 68' vorgesehen, in die am isolierenden Steckereinsatz angeformte Rastnasen 69' eingreifen und den Steckereinsatz innerhalb der Metallhülse 65 halten.
Ebenso sind sind Rastmittel 68 und 69 am Montagearm 66 und der Metallhaube 64 vorgesehen, mittels derer die Metallhaube auf der Metallhülse zu verrasten ist.
Auf der hier gezeigten Steckseite sind polarisierenden Strukturen 62 vorgesehen, in denen Steckerstifte angeordnet sind, entsprechend den im Stecker 1 angeordneten Buchsenkontakten 53 im Steckereinsatzes 50.The Fig. 6 shows a prepared for mounting on a printed circuit board 7 mating connector 60 in an exploded view.
The mating connector 60 is formed from a metal sleeve 65, a plug insert 61 and a metal cap 64.
The metal sleeve has two mounting arms 66, each with an angled end, by means of which a ground connection to the circuit board 7 is made possible.
Furthermore, in the mounting arms 66 detent openings 68 'are provided, engage in the formed on the insulating plug insert locking lugs 69' and hold the plug insert within the metal sleeve 65.
Likewise, locking means 68 and 69 are provided on the mounting arm 66 and the metal hood 64, by means of which the metal hood is to lock on the metal sleeve.
Polarizing structures 62 are provided on the plug-in side shown here, in which plug pins are arranged, corresponding to the socket contacts 53 in the plug insert 50 arranged in the plug 1.

Die Metallhülse 65 weist darüber hinaus an den Schmalseiten jeweils zwei Rastöffnungen 67 auf, in die, bei einer gesteckten Verbindung mit dem Stecker 1, die bereits weiter oben beschriebenen Rasthaken 28 der Metallfingern 27 eintauchen und somit den Verrastungsmechanismus der Steckverbindung bilden.The metal sleeve 65 also has on the narrow sides in each case two latching openings 67 into which, in the case of a mated connection with the plug 1, the latching hooks 28 of the metal fingers 27 already described above are immersed and thus form the latching mechanism of the plug connection.

In der Fig. 7 ist eine gesteckte Position des Steckers 1 mit dem Gegenstecker 60 dargestellt. Dabei ist die Hülse 40 teilweise aufgeschnitten gezeigt, so dass in dem hier gezeigten verriegelten Zustand erkennbar ist, wie die Rasthaken 28 in den Rastöffnungen 67 des Gegensteckers 60 eintauchen und die Verriegelung zwischen Stecker und Gegenstecker sicherstellen.In the Fig. 7 an inserted position of the plug 1 with the mating connector 60 is shown. In this case, the sleeve 40 is shown partially cut open, so that it can be seen in the locked state shown here, as the latching hooks 28 dive into the latching openings 67 of the mating connector 60 and ensure the lock between the plug and mating connector.

Zudem ist noch die Montage des Gegensteckers auf der Leiterplatte 7 gezeigt wobei die Metallhaube 64 zur besseren Sicht auf den Anschlussbereich 63 weggelassen wurde.In addition, the assembly of the mating connector is still shown on the circuit board 7 wherein the metal cap 64 has been omitted for better visibility on the connection portion 63.

Der hier beschriebene Gegenstecker für eine Leiterplatte, kann problemlos auch als Gegenstecker mit einem Kabelanschluss gefertigt sein, wobei der Verriegelungsmechanismus unverändert bleibt.The mating connector for a printed circuit board described here, can also be easily manufactured as a mating connector with a cable connection, wherein the locking mechanism remains unchanged.
