Description

Die Erfindung betrifft einen elektrischen Nullkraftsteckverbinder mit einem Steckhülsengehäuse, welches Aufnahmen für mehrere Hülsenkontakte aufweist, und einem Aggregateanschluss, der die Hülsenkontakte kontaktierende Steckerstifte aufweist, wobei die Hülsenkontakte jeweils einen Kontaktlamellen ausbildenden Grundkörper und eine gegenüber dem Grundkörper verschiebliche Spannhülse aufweisen, wobei bei einer Verschiebung die Spannhülsen gegen den Grundkörper die Spannhülsen die Kontaktlamellen an die Steckerstifte des Aggregateanschlusses anpressen, wobei das Steckhülsengehäuse einen federnden Rasthaken aufweist, der nach dem Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss mit einer Rastnase des Aggregateanschlusses verrastet, und wobei das Steckhülsengehäuse ein Dichtelement aufweist, welches nach dem Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss an der Innenwand des Aggregateanschlusses anliegt.The invention relates to an electrical zero-force connector having a receptacle housing, which has receptacles for a plurality of sleeve contacts, and an aggregate connection, the sleeve contacts contacting plug pins, wherein the sleeve contacts each have a contact blades forming base body and a relative to the base slidable clamping sleeve, wherein during a displacement the Clamping sleeves against the base body, the clamping sleeves press the contact blades to the connector pins of the unit connection, wherein the socket housing has a resilient latching hook which locks after assembly of socket housing and unit connection with a locking lug of the unit connection, and wherein the socket housing has a sealing element, which after assembly from the socket housing and the unit connection to the inner wall of the unit connection.

Ein derartiger elektrischer Nullkraftsteckverbinder ist aus der deutschen Offenlegungsschrift DE 10 2005 040 952 A1 bekannt. Dieser Nullkraftsteckverbinder weist ein Steckhülsengehäuse mit zwei als Umgehäuse und Fixiergehäuse bezeichneten Gehäuseteilen auf, die relativ zueinander zwei Raststellungen einnehmen können. Befinden sich die Gehäuseteile in einer ersten Raststellung, so halten mit dem Umgehäuse verbundene Spannhülsen die Hülsenkontakte geöffnet, so dass die Kontaktstifte eines Gegensteckverbinders, der als Aggregateanschlusses bezeichnet ist, nahezu kraftfrei mit den Hülsenkontakten verbunden werden können. Das Anfügen des Aggregateanschlusses löst die Fixierung der Rastverbindung zwischen den Gehäuseteilen des Steckhülsengehäuses und bringt die diese relativ zueinander in eine zweite Raststellung, in der die Spannhülsen Kontaktlamellen der Hülsenkontakte an die Kontaktstifte des Aggregateanschlusses anpressen.Such a zero-force electrical connector is known from the German patent application DE 10 2005 040 952 A1 known. This zero-force connector has a receptacle housing with two housing parts designated as housing housing and fixing housing, which can occupy two locking positions relative to each other. If the housing parts are in a first detent position, clamping sleeves connected to the surrounding housing keep the sleeve contacts open so that the contact pins of a mating connector, which is referred to as an aggregate connection, can be connected to the sleeve contacts almost without force. The attachment of the unit connection solves the fixation of the locking connection between the housing parts of the receptacle housing and brings them relative to each other in a second detent position in which the Clamping sleeves Press the contact lamellae of the sleeve contacts onto the contact pins of the unit connection.

Der Verrastungsmechanismus zwischen dem Umgehäuse und dem Fixiergehäuse bewirkt, dass die Kontaktstifte des Aggregateanschlusses nahezu kraftfrei in die Hülsenkontakte eingeschoben werden können, und eine Kontaktkraft zwischen den Kontaktlamellen der Hülsenkontakte und den Kontaktstiften erst in der letzten Phase des Zusammenfügens der Steckverbinderteile erzeugt wird. Damit sich mechanische Einwirkungen auf das Umgehäuse oder den Aggregateanschluss nicht auf die miteinander verbundenen elektrischen Kontaktelemente übertragen oder die Verbindungen der Kontaktelemente sogar auftrennen können, ist an einer äußeren Wand des Umgehäuses eine federnde Rastwippe angeformt. Beim Anfügen an den Aggregateanschluss rastet ein Federarm der Rastwippe über eine Rastnase am Aggregateanschluss und verbindet damit beide Steckverbinderteile formschlüssig miteinander. Das Öffnen dieser Rastverbindung zum bedarfsweisen Trennen der beiden Steckverbinderteile kann durch Druckausübung auf den freien Federarm der Rastwippe bewirkt werden.The latching mechanism between the surrounding housing and the fixing housing causes the contact pins of the unit connection can be inserted into the sleeve contacts almost force-free, and a contact force between the contact blades of the sleeve contacts and the contact pins is generated only in the last phase of assembly of the connector parts. So that mechanical effects on the surrounding housing or the aggregate connection can not be transferred to the interconnected electrical contact elements or even disconnect the connections of the contact elements, a resilient detent rocker is formed on an outer wall of the surrounding housing. When attached to the unit connection, a spring arm of the locking rocker engages via a latching lug on the unit connection and thus connects the two connector parts with one another in a form-fitting manner. The opening of this latching connection to the need-based separation of the two connector parts can be effected by applying pressure to the free spring arm of the locking rocker.

Bei diesem vorbekannten Nullkraftsteckverbinder erfolgen das Verschieben der Spannhülsen an den Hülsenkontakten und das Verrasten von Rastwippe und Rastnase am Umgehäuse und am Aggregateanschluss mechanisch unabhängig voneinander. Es besteht daher keine Gewähr dafür, dass beim Verschieben der Spannhülsen auch die Rastverbindung zwischen Umgehäuse und Aggregateanschluss hergestellt wird oder umgekehrt, dass bei miteinander verrastetem Umgehäuse und Aggregateanschluss auch die Spannhülsen an den Hülsenkontakten bis in ihre Endstellung verschoben sind.In this known zero-force connector, the displacement of the clamping sleeves on the sleeve contacts and the locking of locking rocker and locking lug on the housing and the unit connection mechanically independent of each other. Therefore, there is no guarantee that when moving the clamping sleeves and the locking connection between the housing and the unit connection is made or vice versa that with interlocked housing and housing connection and the clamping sleeves are moved to the sleeve contacts to their final position.

Es stellte sich daher die Aufgabe, einen elektrischen Nullkraftsteckverbinder zu schaffen, der ein vollständiges elektrisches und mechanisches Verbinden der Steckverbinderteile sicherstellt.It was therefore an object to provide a zero-force electrical connector that ensures complete electrical and mechanical connection of the connector parts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass am Steckhülsengehäuse ein Riegel angeordnet ist, der nach dem Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss gegen das Steckhülsengehäuse verschiebbar ist und der nach dem Verschieben die Rastverbindung von Rasthaken und Rastnase arretiert, und dass der Riegel mit einem durch mindestens eine Ausnehmung des Dichtelements geführten und mit den Spannhülsen gekoppelten Schieber verbunden ist und den Schieber bei einer Verschiebung mitbewegt, wobei die Bewegung des Schiebers die Spannhülsen gegen den Grundkörper der Hülsenkontakte verschiebt.This object is achieved in that the receptacle housing a latch is arranged, which is displaceable after the assembly of receptacle housing and unit port against the receptacle housing and locked after moving the locking connection of latching hook and detent, and that the latch with a by at least one Recess of the sealing element guided and coupled to the clamping sleeves slide is connected and moves the slider during a displacement, wherein the movement of the slide shifts the clamping sleeves against the main body of the sleeve contacts.

Bei dem erfindungsgemäßen Nullkraftsteckverbinder erfolgt somit das Verrasten von Steckhülsengehäuse und Aggregateanschluss und das Verschieben der Spannhülsen mittels mechanisch gekoppelter Elemente, so dass beide mechanischen Abläufe nur gemeinsam erfolgen können. Die von außen gut erkennbare Schiebestellung des Riegels zeigt dem Anwender zugleich auch die Verschiebeposition der Spannhülsen an.In the case of the zero-force plug connector according to the invention, the latching of plug-in socket housing and unit connection and the displacement of the clamping sleeves by means of mechanically coupled elements thus take place, so that both mechanical processes can only take place together. The well-visible from the outside sliding position of the bolt also shows the user at the same time the displacement position of the clamping sleeves.

Hierbei stellte sich allerdings das Problem, auf die Spannhülsen mechanisch zuzugreifen, die im Inneren einer Kammer angeordnet sind, die durch das mit dem Aggregateanschluss verbundene Steckverbindergehäuse ausgebildet wird, und die durch ein Dichtelement gegen Feuchtigkeit geschützt ist. Ein Verzicht auf das Dichtelement hätte zu einer mangelhaften Abdichtung der Steckverbinderanordnung geführt.Here, however, there was the problem of mechanically accessing the clamping sleeves, which are arranged in the interior of a chamber which is formed by the connector housing connected to the power connector, and which is protected by a sealing element against moisture. A waiver of the sealing element would have led to a poor seal of the connector assembly.

Dieses Problem wird durch einen Schieber gelöst der durch mindestens eine Ausnehmung des Dichtelements hindurchgeführt ist. Hierdurch kann das Dichtelement an seinem Platz verbleiben und zugleich die Verbindung von Schieber und Riegels abdichten.This problem is solved by a slider which is passed through at least one recess of the sealing element. In this way, the sealing element can remain in place and at the same time seal the connection between slide and bolt.

Vorteilhaft ist es, dass der Riegel erst nach dem Zusammenfügen von Steckhülsengehäuse und Aggregateanschluss gegen das Steckhülsengehäuse verschiebbar ist. Beim Anfügen des Steckhülsengehäuses befindet sich dadurch der Riegel in der korrekten Montageposition, was zusätzlichen Montageaufwand vermeidet. Dies kann auf vorteilhafte Weise dadurch realisiert sein, dass der Riegel einen angeformten Vorsprung aufweist, der zunächst durch den Rasthaken des Steckhülsengehäuses blockiert ist und durch das Verrasten des Rasthakens an der Rastnase des Umgehäuses freigegeben wird.It is advantageous that the bolt only after the assembly of receptacle housing and unit connection against the Socket housing is displaceable. When attaching the receptacle housing is thereby the bolt in the correct mounting position, which avoids additional installation effort. This can be realized in an advantageous manner by the fact that the latch has a molded projection which is initially blocked by the latching hook of the socket housing and is released by the latching of the latching hook on the locking lug of the surrounding housing.

In der Figur 1 sind zwei miteinander verbindbare Steckverbinderteile 1, 6 eines erfindungsgemäßen Nullkraftsteckverbinders im noch unverbundenen Zustand dargestellt. Die Steckverbinderteile 1, 6 werden hier speziell auch als Steckhülsengehäuse 1 und Aggregateanschluss 6 bezeichnet.In the FIG. 1 are two interconnected connector parts 1, 6 of a zero force connector according to the invention shown in the still unconnected state. The connector parts 1, 6 are referred to here specifically as a receptacle housing 1 and unit connection 6.

Das Steckhülsengehäuse 1 besteht aus einem äußeren Umgehäuse 15 und einem inneren Kontaktträger 16, die entweder einstückig oder als miteinander verbundene Einzelteile ausgeführt sein können und die besonders deutlich in der Figur 5 erkennbar sind. Der Kontaktträger 16 besitzt mehrere röhrenartige Aufnahmen 25, in die aus Metall geformte Hülsenkontakte 2 eingesetzt sind.The receptacle housing 1 consists of an outer housing 15 and an inner contact carrier 16, either in one piece or as one another Connected items can be executed and the most clearly in the FIG. 5 are recognizable. The contact carrier 16 has a plurality of tube-like receptacles 25 are inserted into the metal-shaped sleeve contacts 2.

Einen Hülsenkontakt 2, wie er bereits in der DE 10 2005 040 952 A1 beschrieben ist, zeigt als Einzelteil die Figur 7 in zwei Ansichten a) und b). Der Hülsenkontakt 2 besteht aus einem metallenen Grundkörper 4, der mit einer elektrischen Leitung 22 verbunden ist. Die Leitung 22 weist einen elektrischen Leiter 17 auf, der mittels einer Crimpverbindung 20 elektrisch und mechanisch mit dem Grundkörper 4 verbunden ist. Ein die elektrische Leitung 22 umgebendes Dichtgummi 18 ist im Übergangsbereich von der Leitung 22 zum Grundkörper 4 über zwei Biegelaschen 19 am Grundkörper 4 befestigt. Für eine bessere Übersichtlichkeit wurde auf die Darstellung elektrischer Leitungen in den übrigen Figuren verzichtet.A sleeve contact 2, as he already in the DE 10 2005 040 952 A1 is described as an item that shows FIG. 7 in two views a) and b). The sleeve contact 2 consists of a metal base body 4, which is connected to an electrical line 22. The line 22 has an electrical conductor 17, which is electrically and mechanically connected to the base body 4 by means of a crimp connection 20. A sealing rubber 18 surrounding the electrical line 22 is fastened to the base body 4 in the transition region from the line 22 to the base body 4 via two bending tabs 19. For better clarity, the illustration of electrical lines in the other figures was omitted.

Den freien Endabschnitt des Grundkörpers 4 bilden zwei einstückig an den Grundkörper 4 angeformte, nebeneinander liegende Kontaktlamellen 3, in deren Zwischenraum 21 ein in dieser Figur nicht dargestellter flacher Steckerstift einfügbar ist. Die Enden der Kontaktlamellen 3 sind jeweils nach außen umgebogen. Am Grundkörper 4 federnd befestigt ist eine den Grundkörperquerschnitt teilweise umgreifende Spannhülse 5. Die Spannhülse 5 besitzt in Querrichtung mehrere schlitzförmige Durchbrüche 23, welche eine flache Federkennlinie bewirken. Des Weiteren ist die Spannhülse 5 entlang des Grundkörpers 4 verschieblich angeordnet. Befindet sich die Spannhülse 5 im Bereich der Kontaktlamellen 3, wie in der Ansicht b) gezeigt, so drückt die Spannhülse 5 die Kontaktlamellen 3 aufeinander zu. Ist die Spannhülse 5 dagegen, entsprechend der Ansicht a), entfernt von den Kontaktlamellen 3 angeordnet, so wirken von der Spannhülse 5 keine Druckkräfte auf die Kontaktlamellen 3. Die letztgenannte Anordnung der Spannhülse 5 auf dem Grundkörper 4 ermöglicht es daher, einen Steckerstift nahezu kräftefrei in den Zwischenraum 21 zwischen den Kontaktlamellen 3 einzufügen.The free end portion of the base body 4 form two integrally formed on the base body 4, adjacent contact blades 3, in the space 21 a not shown in this figure flat pin is inserted. The ends of the contact blades 3 are each bent to the outside. Fastened to the base body 4 is a spring body cross-section partially encompassing clamping sleeve 5. The clamping sleeve 5 has a plurality of slot-shaped openings 23 in the transverse direction, which cause a flat spring characteristic. Furthermore, the clamping sleeve 5 is arranged displaceably along the base body 4. The clamping sleeve 5 is located in the region of the contact blades 3, as shown in the view b), so the clamping sleeve 5 presses the contact blades 3 towards each other. If the clamping sleeve 5, however, arranged according to the view a), away from the contact blades 3, act from the clamping sleeve 5 no pressure forces on the contact blades 3. The latter arrangement of the clamping sleeve 5 on the base body 4 therefore allows a pin almost free of force to insert into the gap 21 between the contact blades 3.

Gemäß der Figur 1 gehört zum Steckhülsengehäuse 1 ein am Umgehäuse 15 verschiebbar angeordneter Riegel 11. Wie die Figuren 4 und 5 verdeutlichen, weist der Riegel 11 zwei Arme 27 auf, die jeweils mit einem Stift 14 eines Schiebers 13 verbunden sind. Die Stifte 14 sind durch Ausnehmungen 12 in einem Dichtelement 10 hindurchgeführt, welches den Kontaktträger 16 umschließt und bei miteinander verbundenen Steckverbinderteilen 1, 6 den Kontaktträger 16 gegen den Aggregateanschluss 6 abdichtet.According to the FIG. 1 belongs to the receptacle housing 1 a displaceably arranged on the surrounding housing 15 latch 11. How the FIGS. 4 and 5 clarify, the latch 11 has two arms 27 which are each connected to a pin 14 of a slider 13. The pins 14 are passed through recesses 12 in a sealing element 10, which encloses the contact carrier 16 and seals the contact carrier 16 against the aggregate connection 6 when the connector parts 1, 6 are connected to one another.

Die Durchführung eines Stifts 14 durch eine Ausnehmung 12 im Dichtelement 10 ist in der Figur 6 in einer Vergrößerung eines Ausschnitts A aus der Figur 5 dargestellt. Der Stift 14 kann entlang der Ausnehmung 12 verschoben werden, wobei das gummielastische Dichtelement 10 den Stift 14 stets feuchtigkeitsdicht umschließt. Für die Realisierung des hier beispielhaft zylinderförmig dargestellten Stifts 14 kann selbstverständlich auch eine andere, beispielsweise ovale oder mehreckige Querschnittskontur vorgesehen werden.The passage of a pin 14 through a recess 12 in the sealing element 10 is in the FIG. 6 in an enlargement of a section A from the FIG. 5 shown. The pin 14 can be moved along the recess 12, wherein the rubber-elastic sealing element 10, the pin 14 always encloses moisture-tight. Of course, another, for example oval or polygonal cross-sectional contour can be provided for the realization of the pin 14 shown here by way of example as a cylinder.

In der Figur 5 und besonders deutlich in der Figur 4 ist als ein weiterer Bestandteil des Schiebers 13 ein Rahmen 28 erkennbar, welcher mit beiden Stiften 14 verbunden ist. Anformungen 30 am Rahmens 28 greifen in die schlitzförmigen Durchbrüche 23, abgebildet in der Figur 7, der Spannhülsen 5 ein, wodurch eine vertikale Bewegung des Schiebers 13 die Spannhülsen 5 gegen den Grundkörper 4 der Hülsenkontakte 2 verschiebt.
Das Verbinden des Steckhülsengehäuses 1 mit dem Aggregateanschluss 6 erfolgt wie folgt. Wie bereits erwähnt zeigt die Figur 1 die beiden Steckverbinderteile 1, 6 im noch unverbundenen Zustand. Der Riegel 11 am Steckhülsengehäuse 1 befindet sich in seiner Anfangsposition, da der federnd am Steckhülsengehäuse 1 angeformte Rasthaken 8 ein Hindernis für den am Riegel 11 angeformten Vorsprung 26 dargestellt und daher eine Verschiebung des Riegels 11 gegen das Steckhülsengehäuse 1 blockiert. Da die Spannhülsen 5 über den Schieber 13 mechanisch mit dem Riegel 11 gekoppelt sind, befinden sich auch die Spannhülsen 5 der Hülsenkontakte 2 in ihrer Grundstellung, in welcher die Steckerstifte 7 des Aggregateanschlusses 6 in die Hülsenkontakte 2 einschiebbar sind.In the FIG. 5 and especially clear in the FIG. 4 is seen as a further part of the slider 13, a frame 28 which is connected to two pins 14. Anformungen 30 on the frame 28 engage in the slot-shaped openings 23, shown in the FIG. 7 , the clamping sleeves 5, whereby a vertical movement of the slider 13, the clamping sleeves 5 against the base body 4 of the sleeve contacts 2 moves.
The connection of the receptacle housing 1 to the unit connection 6 takes place as follows. As already mentioned shows the FIG. 1 the two connector parts 1, 6 in the still unconnected state. The latch 11 on the receptacle housing 1 is in its initial position, since the resiliently molded on the receptacle housing 1 latching hooks 8 an obstacle to the integrally formed on the bolt 11 projection 26 and therefore blocks a displacement of the bolt 11 against the receptacle housing 1. Because the Clamping sleeves 5 are mechanically coupled via the slide 13 to the latch 11, are also the clamping sleeves 5 of the sleeve contacts 2 in their normal position in which the connector pins 7 of the unit connection 6 in the sleeve contacts 2 are inserted.

Hierdurch kann das Steckhülsengehäuse 1 an den Aggregateanschluss 6 angefügt werden, wobei die Steckerstifte 7 in zugeordnete Hülsenkontakte 2 einfahren. Der hierdurch erreichte Montagezustand ist in der Figur 2 in einer Schnittansicht dargestellt. Erkennbar ist, dass der Rasthaken 8 des Steckhülsengehäuses 1 nun hinter der Rastnase 9 des Aggregateanschlusses 6 verrastet ist. Die Rastnase 9 liegt an dem Vorsprung 26 des Riegels 11 an, wodurch der Vorsprung 26 bei einer Druckeinwirkung auf das Betätigungselement 29 des Riegels 11 über die Rastnase 9 gleitet und der Riegel 11 gegen das Steckhülsengehäuse 1 verschoben wird.In this way, the receptacle housing 1 can be added to the unit connection 6, wherein the plug pins 7 retract into associated sleeve contacts 2. The assembly state achieved thereby is in the FIG. 2 shown in a sectional view. It can be seen that the latching hook 8 of the receptacle housing 1 is now latched behind the latching lug 9 of the unit connection 6. The detent 9 abuts against the projection 26 of the bolt 11, whereby the projection 26 slides at a pressure on the actuator 29 of the bolt 11 via the locking lug 9 and the bolt 11 is moved against the socket housing 1.

Bei dieser Verschiebebewegung nimmt der Riegel 11 den mechanisch angekoppelten Schieber 13 mit. Die beiden durch das Dichtelement 10 geführten Stifte 14 sind an ihrer Unterseite einstückig mit dem ovalen oder rechteckförmigen Rahmen 28 verbunden, welcher eine der Zahl der Hülsenkontakte 2 entsprechende Anzahl von Anformungen 30 aufweist, welche mechanisch an den Spannhülsen 5 angreifen. Zusätzlich ist ein Sekundärriegel 24 vorgesehen, welcher mit beiden Stiften 14 verbunden ist und der an der Oberseite der Spannhülsen 5 anliegt. Die Bewegung des Schiebers 13 verschiebt so die Spannhülsen 5 gegen die Hülsenkontakte 2, wodurch sich die Kontaktlamellen 3 der Hülsenkontakte 2 eng um die Steckerstifte 7 des Aggregateanschlusses 6 schließen.In this sliding movement of the bolt 11 takes the mechanically coupled slider 13 with. The two guided through the sealing element 10 pins 14 are integrally connected at its bottom with the oval or rectangular frame 28, which has a number of the sleeve contacts 2 corresponding number of projections 30 which mechanically engage the clamping sleeves 5. In addition, a secondary bar 24 is provided, which is connected to both pins 14 and which bears against the upper side of the clamping sleeves 5. The movement of the slider 13 thus displaces the clamping sleeves 5 against the sleeve contacts 2, whereby the contact blades 3 of the sleeve contacts 2 close tightly around the connector pins 7 of the unit connection 6.

Der Riegel 11, der Schieber 13 und die Spannhülsen 5 erreichen schließlich ihre Endpositionen, die in der Darstellung der Figur 3 ersichtlich sind. Der Riegel 11 blockiert in seiner Endposition die Beweglichkeit von Rasthaken 8 und Rastnase 9 relativ zueinander, wodurch das Steckhülsengehäuse 1 und der Aggregateanschluss 6 nun formschlüssig miteinander verbunden und arretiert sind. Das Arretieren der Steckverbinderteile 1, 6 gegeneinander und das Aktivieren der Hülsenkontakte 2 durch die Verschiebung der Spannhülsen 5 wird somit gleichzeitig und in einem einzigen Montageschritt durch die Verschiebung des Riegels 11 erreicht.The bolt 11, the slider 13 and the clamping sleeves 5 finally reach their end positions, which in the illustration of FIG. 3 can be seen. The latch 11 is blocked in its final position, the mobility of latching hook 8 and detent 9 relative to each other, whereby the receptacle housing 1 and the aggregate connection 6 is now positively connected to each other and locked. The locking of the connector parts 1, 6 against each other and the activation of the sleeve contacts 2 by the displacement of the clamping sleeves 5 is thus achieved simultaneously and in a single assembly step by the displacement of the bolt 11.

Das Trennen der Steckverbinderteile 1, 6 erfolgt in genau umgekehrter Abfolge des Verbindungsvorgangs. Um die beiden Steckverbinderteile 1, 6 voneinander zu lösen, ist zunächst der Riegel 11 zu ziehen, dass heißt in die in der Figur 2 dargestellte Position zu bringen. Danach kann das Steckhülsengehäuse 1 vom Aggregateanschluss 6 getrennt werden.The separation of the connector parts 1, 6 takes place in exactly the reverse sequence of the connection process. To solve the two connector parts 1, 6 from each other, the bolt 11 is first to pull, that is in the in the FIG. 2 to bring shown position. Thereafter, the receptacle housing 1 can be separated from the unit port 6.
