Bei dem ersten Kontaktelement handelt es sich zum Beispiel um einen Kontaktstift, der von einer elektrischen Einrichtung, wie einer Spule ausgeht, an die der Steckverbinder anschließbar ist. Aus der deutschen Pa- tentschrift DE 102 16 406 C1 ist ein elektrischer winkelförmiger Steckverbinder mit einem elektrische Kontakte enthaltenden Isolierkörper bekannt, der in Gebrauchsstellung in einem ersten Winkelschenkel des Steckverbinders angeordnet und festgelegt ist. In der Gebrauchsstellung wird der erste Winkelschenkel mit Hilfe einer Befestigungsschraube in axialer Rich- tung formschlüssig festgelegt.The first contact element is, for example, a contact pin, which starts from an electrical device, such as a coil, to which the connector can be connected. From the German patent DE 102 16 406 C1 an electrical angle-shaped connector with an electrical body containing insulating body is known, which is arranged and fixed in the use position in a first angle leg of the connector. In the position of use, the first angle leg is fixed positively in the axial direction by means of a fastening screw.

Die Aufgabe ist bei einem elektrischen Steckverbinder mit einem Gehäuse, in dem ein Einsatz aufgenommen ist, der einen Aufnahmeraum für ein erstes Kontaktelement aufweist, das in dem Aufnahmeraum mit einem zweiten Kontaktelement in Kontakt kommt, wenn das erste Kontaktelement in den Aufnahmeraum eingesteckt wird, dadurch gelöst, dass der Aufnahmeraum von einem Blockierelement begrenzt wird, das, wenn das erste Kontaktelement in den Aufnahmeraum eingesteckt ist, durch das erste Kontaktelement in einer Blockierstellung gehalten wird, in der das Blockierelement den Einsatz in dem Gehäuse blockiert. Durch das Bio- ckierelement wird der Einsatz in dem Gehäuse fixiert, solange das erste Kontaktelement in den Aufnahmeraum eingesteckt ist. Dadurch wird auf einfache Art und Weise ein unerwünschtes Entfernen des Einsatzes aus dem Gehäuse verhindert. Wenn das erste Kontaktelement aus dem Auf- nahmeraum herausgezogen wird, dann wird das Blockierelement freigegeben. Das Blockierelement kann dann, zum Beispiel mit einem geeigneten Werkzeug, aus seiner Blockierstellung in eine Lösestellung gebracht werden, in der der Einsatz aus dem Gehäuse entfernt werden kann.The object is in an electrical connector having a housing in which an insert is received, having a receiving space for a first contact element, which comes in the receiving space with a second contact element in contact when the first contact element is inserted into the receiving space, characterized solved that the receiving space is limited by a blocking element, which, when the first contact element is inserted into the receiving space, is held by the first contact element in a blocking position in which the blocking element blocks the insert in the housing. Through the organic ckierelement the insert is fixed in the housing, as long as the first contact element is inserted into the receiving space. As a result, undesired removal of the insert from the housing is prevented in a simple manner. When the first contact element is pulled out of the receiving space, then the blocking element is released. The blocking element can then be brought, for example with a suitable tool, from its blocking position into a release position in which the insert can be removed from the housing.
Ein bevorzugtes Ausführungsbeispiel des elektrischen Steckverbinders ist dadurch gekennzeichnet, dass das Blockierelement von einem Schnapphaken gebildet wird, der von dem Einsatz ausgeht. Der Schnapphaken ist vorzugsweise in seine Blockierstellung vorgespannt. Diese Vorspannkraft muss überwunden werden, um das Blockierelement aus der Blockierstellung in die Lösestellung zu bringen.A preferred embodiment of the electrical connector is characterized in that the blocking element is formed by a snap hook, which emanates from the insert. The snap hook is preferably biased in its blocking position. This biasing force must be overcome to bring the blocking element from the blocking position to the release position.

This allows different mounting positions of the insert in the housing. There may also be provided a plurality of blocking elements on the insert.
Ein weiteres bevorzugtes Ausführungsbeispiel des elektrischen Steckverbinders ist dadurch gekennzeichnet, dass das zweite Kontakelement so in dem Aufnahmeraum angeordnet werden kann, dass das erste Kontaktelement zwischen dem zweiten Kontakelement und dem Blockierelement angeordnet ist, wenn das erste Kontaktelement in den Aufnahmeraum eingesteckt ist. Vorzugsweise ist das erste Kontaktelement zwischen dem zweiten Kontaktelement und dem Blockierelement eingeklemmt. Dadurch wird einerseits ein stabiler Kontakt zwischen den beiden Kontaktelementen sichergestellt.

Ein weiteres bevorzugtes Ausführungsbeispiel des elektrischen Steckverbinders ist dadurch gekennzeichnet, dass von der Basis zwei Schenkel abgewinkelt sind. Einer der Schenkel verbindet die Basis mit dem zweiten Kontaktelement. Der andere Schenkel stützt sich mit seinem freien Ende vorzugsweise an dem Einsatz ab. Das freie Ende mit der Basis und den Schenkeln ist im Wesentlichen U-förmig ausgebildet, wobei die beiden Schenkel nicht senkrecht, sondern in einem größeren Winkel als 90 Grad zu der Basis angeordnet sind.

Dadurch wird sichergestellt, dass das Blockierelement in seiner Blockierstellung bleibt, solange die weiteren Kontaktelemente eingesteckt sind. Erst wenn die weiteren Kontaktelemente keinen Kontakt mehr haben, kann der Einsatz entfernt werden, weil erst dann das Blockierelement von dem ersten Kontaktelement freigegeben wird. Dadurch wird ein unbeabsichtigtes Berühren von stromführenden Teilen sicher verhindert.A further preferred embodiment of the electrical connector is characterized in that the insert has two further receiving spaces for two further contact elements, which emanate from one or the electrical device. About the other contact elements of the electrical device is supplied electrical energy. The further contact elements are preferably chamfer pins.

As a result, unintentional contact with live parts is reliably prevented.
Ein weiteres bevorzugtes Ausführungsbeispiel des elektrischen Steckverbinders ist dadurch gekennzeichnet, dass von dem Gehäuse ein Anschlussarm abgewinkelt ist. Der elektrische Steckverbinder ist vorzugsweise winkelförmig ausgeführt. Von dem abgewinkelten Anschlussarm geht ein elektrisches Anschlusskabel aus, durch das der elektrischen Ein- richtung über den elektrischen Steckverbinder elektrische Energie zugeführt wird.Another preferred embodiment of the electrical connector is characterized in that an arm is angled from the housing. The electrical connector is preferably designed angular. From the angled connecting arm emanates an electrical connecting cable through which electrical power is supplied to the electrical device via the electrical connector.
Ein weiteres bevorzugtes Ausführungsbeispiel des elektrischen Steckverbinders ist dadurch gekennzeichnet, dass das Gehäuse und der Einsatz ein gemeinsames Durchgangsloch aufweisen. Das Durchgangsloch dient zum Durchstecken mindestens einer Befestigungsschraube, mit welcher der elektrische Steckverbinder an einer elektrischen Einrichtung, wie einer Spule, befestigbar ist. Die Befestigung mit der Befestigungsschraube erfolgt unabhängig von der Fixierung des Einsatzes in dem Gehäuse mit Hilfe des Blockierelements.Another preferred embodiment of the electrical connector is characterized in that the housing and the insert have a common through hole. The through hole is used to insert at least one fastening screw, with which the electrical connector to an electrical device, such as a coil, can be fastened. The attachment with the fastening screw is independent of the fixation of the insert in the housing by means of the blocking element.

In Figur 1 ist ein elektrischer Steckverbinder 1 , der an eine elektrische Einrichtung 2 angeschlossen ist, im Schnitt dargestellt. Bei der elektrischen Einrichtung 2 handelt es sich um eine Spule 3 eines Magnetventils. Der elektrische Steckverbinder 1 wird auch als Konnektor bezeichnet und wird vorzugsweise für elektrische Einrichtungen, insbesondere Spulen, mit Steckerstiften, zum Beispiel nach dem Standard EN 175301-803 verwendet. Zwischen der Spule 3 und dem elektrischen Steckverbinder 1 ist eine Dichtung 4 angeordnet. Der elektrische Steckverbinder 1 dient dazu, eine elektrische Spannung in sicherer Art und Weise an die Spule 3 anzulegen. Dabei soll insbesondere ein Kontakt mit stromführenden Teilen im Inneren des elektrischen Steckverbinders 1 verhindert werden.In Figure 1, an electrical connector 1, which is connected to an electrical device 2, shown in section. The electrical device 2 is a coil 3 of a solenoid valve. The electrical connector 1 is also referred to as a connector and is preferably used for electrical devices, in particular coils, with plug pins, for example according to the standard EN 175301-803. Between the coil 3 and the electrical connector 1, a seal 4 is arranged. The electrical connector 1 serves to apply an electric voltage in a safe manner to the coil 3. In particular, a contact with current-carrying parts in the interior of the electrical connector 1 is to be prevented.
Der elektrische Steckverbinder 1 umfasst ein Gehäuse 5, das auch als Kappe bezeichnet wird. Das Gehäuse 5 umfasst einen Gehäusegrundkörper 6, der im Wesentlichen quaderförmig ausgebildet ist und von dem ein Anschlussarm 8 ausgeht. Der Anschlussarm 8 ist einstückig mit dem Gehäusegrundkörper 6 verbunden. In das freie Ende des Anschlussarms 8 ist ein Kabelverschraubungselement 9 eingeschraubt. In dem Anschluss- arm 8 ist ein Dichtungselement 10 angeordnet. Zwischen dem Dichtungselement 10 und dem Kabelverschraubungselement 9 ist ein Metallring 14 mit einem rechteckigen Querschnitt angeordnet. Das Kabelverschraubungselement 9 gehört zu einem (nicht dargestellten) elektrischen Anschlusskabel. Der Gehäusegrundkörper 6 umfasst einen Hohlraum 16, der sich bis in den Anschlussarm 8 hinein erstreckt. Der Hohlraum 16 ist zur Spule 3 beziehungsweise zur Dichtung 4 hin offen und ist von einer Gehäusewand 18 des Gehäusegrundkörpers 6 umgeben. Die Gehäusewand 18 erstreckt sich in Umfangsrichtung um den Gehäusegrundkörper 6 herum. Im Bereich der Öffnung des Grundkörpers 6 zur Spule 3 hin sind innen in der Gehäusewand 18 zwei Rastausnehmungen 21 , 22 sichtbar. Die Rastaus- nehmungen 21 , 22 werden von Vertiefungen in der Gehäusewand 18 gebildet.The electrical connector 1 comprises a housing 5, which is also referred to as a cap. The housing 5 comprises a housing base body 6, which is formed substantially cuboid-shaped and from which a connecting arm 8 starts. The connecting arm 8 is integrally connected to the housing base body 6. In the free end of the connecting arm 8 a Kabelverschraubungselement 9 is screwed. In the connecting arm 8, a sealing element 10 is arranged. Between the sealing element 10 and the cable gland 9, a metal ring 14 is arranged with a rectangular cross-section. The cable gland element 9 belongs to a (not shown) electrical connection cable. The housing base body 6 comprises a cavity 16, which extends into the connecting arm 8 in. The cavity 16 is open to the coil 3 and to the seal 4 and is surrounded by a housing wall 18 of the housing base body 6. The housing wall 18 extends in the circumferential direction around the housing base body 6 around. In the area of the opening of the main body 6 to the coil 3, inside the housing wall 18, two latching recesses 21, 22 are visible. The latching recesses 21, 22 are formed by depressions in the housing wall 18.
In dem von der Gehäusewand 18 und dem Gehäusegrundkörper 6 begrenzten Hohlraum 16 ist ein Einsatz 24 aufgenommen. Bei dem Einsatz 24 handelt es sich um einen Isolierkörper mit einem zentralen Durchgangsloch 26. Das zentrale Durchgangsloch 26 setzt sich in einem zentralen Durchgangsloch 28 in dem Gehäusegrundkörper 6 fort. Auf der ande- ren Seite setzt sich das zentrale Durchgangsloch 26 in einem Durchgangsloch 29 der Dichtung 4 fort. Die Durchgangslöcher 26, 28, 29 bilden ein gemeinsames Durchgangsloch, durch das sich eine Befestigungsschraube 30 mit ihrem Schaft hindurch erstreckt. Die Befestigungsschraube 30 weist einen Schraubenkopf 31 auf, der unter Zwischenschaltung eines O-Rings 33 in einer Vertiefung des Gehäusegrundkörpers 6 aufgenommen ist.In the limited by the housing wall 18 and the housing base 6 cavity 16 an insert 24 is added. The insert 24 is an insulating body with a central through hole 26. The central through hole 26 continues in a central through hole 28 in the housing base body 6. On the other side, the central through hole 26 continues in a through hole 29 of the seal 4. The through holes 26, 28, 29 form a common through hole, through which a fastening screw 30 extends with its shaft. The fastening screw 30 has a screw head 31, which is received with the interposition of an O-ring 33 in a recess of the housing base body 6.
Der Schaft der Befestigungsschraube 30 ist mit einem Außengewinde versehen. Das freie Ende der Befestigungsschraube 30 ist in ein mit einem Innengewinde versehenes Durchgangsloch 35 eingeschraubt, das in der Spule 3 vorgesehen ist. Im Betrieb ist der elektrische Steckverbinder 1 mit Hilfe der Befestigungsschraube 30 an der Spule 3 befestigt. Dadurch wird der elektrische Steckverbinder 1 sicher an der Spule 3 gehalten. Um den elektrischen Steckverbinder von der Spule 3 zu entfernen, muss die Befestigungsschraube 30 gelöst werden. Dann kann der elektrische Steck- verbinder 1 von der Spule 3 entfernt werden, ohne dass der Einsatz 24 aus dem Gehäuse 5 entfernt wird.The shaft of the fastening screw 30 is provided with an external thread. The free end of the fastening screw 30 is screwed into a provided with an internal thread through hole 35 which is provided in the coil 3. In operation, the electrical connector 1 is secured by means of the fastening screw 30 to the coil 3. As a result, the electrical connector 1 is securely held on the coil 3. To remove the electrical connector from the coil 3, the fastening screw 30 must be solved. Then the electrical plug-in connector 1 are removed from the coil 3, without the insert 24 is removed from the housing 5.
Der Einsatz 24 weist einen Aufnahmeraum 40 für ein erstes Kontaktelement 41 auf. Bei dem ersten Kontaktelement 41 handelt es sich um einen Erdschlussstift, der von der Spule 3 ausgeht. Das erste Kontaktelement 41 ist teilweise in dem zur Spule 3 hin offenen Aufnahmeraum 40 aufgenommen. In dem in Figur 1 dargestellten eingesteckten Zustand des ersten Kontaktelements 41 hat dieses Kontakt zu einem zweiten Kontaktelement 42, das in dem Aufnahmeraum 40 angeordnet ist. Das zweite Kontaktele- ment 42 wird zum Beispiel von einem Blechstreifen gebildet, der (nicht dargestellt) mit dem elektrischen Anschlusskabel verbunden ist.The insert 24 has a receiving space 40 for a first contact element 41. The first contact element 41 is a ground fault pin, which starts from the coil 3. The first contact element 41 is partially accommodated in the receiving space 40 which is open towards the coil 3. In the inserted state of the first contact element 41 shown in FIG. 1, the latter has contact with a second contact element 42 which is arranged in the receiving space 40. The second contact element 42 is formed, for example, by a sheet-metal strip which is connected (not shown) to the electrical connection cable.
Gemäß einem wesentlichen Aspekt der Erfindung ist der Einsatz 24 mit Hilfe eines Blockierelements 45 in dem Gehäuse 5 fixiert. Das Blockierelement 45 funktioniert unabhängig von der Befestigungsschraube 30. So ist es zum Beispiel möglich, den Einsatz 24 zu entfernen, wenn die Befestigungsschraube 30 noch in das Gehäuse 5 und den Einsatz 24 eingesteckt ist. Allerdings muss die Spule 3 und die Dichtung 4 vor dem Entfernen des Einsatzes 24 von dem Gehäuse 5 entfernt werden.According to an essential aspect of the invention, the insert 24 is fixed in the housing 5 by means of a blocking element 45. The blocking element 45 functions independently of the fastening screw 30. Thus, it is possible, for example, to remove the insert 24 when the fastening screw 30 is still inserted into the housing 5 and the insert 24. However, the coil 3 and the gasket 4 must be removed from the housing 5 prior to removal of the insert 24.
In der vergrößerten Darstellung der Figur 2 sieht man, dass das zweite Kontaktelement 42 an seinem freien Ende im Wesentlichen U-förmig mit einer Basis 50 ausgebildet ist. Von der Basis 50 geht ein Schenkel 51 aus, der die Basis 50 mit dem Rest des zweiten Kontaktelements 42 verbindet. Auf der anderen Seite geht von der Basis 50 ein zweiter Schenkel 52 aus, der in einer Ausnehmung des Einsatzes 24 aufgenommen ist. Die Aus- nehmung weist im Querschnitt im Wesentlichen die Gestalt eines Dreiecks auf.In the enlarged view of Figure 2 it can be seen that the second contact element 42 is formed at its free end substantially U-shaped with a base 50. From the base 50 is a leg 51, which connects the base 50 with the rest of the second contact element 42. On the other side, the base 50 is preceded by a second leg 52, which is received in a recess of the insert 24. The recess has essentially the shape of a triangle in cross section.
Die beiden Schenkel 51 , 52 sind jeweils in einem Winkel von etwa 135 Grad zu der Basis 50 angeordnet. Die Enden der Schenkel 51 , 52 stützen sich an dem Einsatz 24 ab. Die Basis 50 liegt an dem ersten Kontaktele- ment 41 an. Auf der der Basis 50 abgewandten Seite des ersten Kontaktelements 41 ist das Blockierelement 45 angeordnet. Das Blockierelement 45 kann, aber muss sich nicht in Anlage an dem ersten Kontaktelement 41 befinden. Das Blockierelement 45 ist einstückig mit dem Einsatz 24 ver- bunden und hat die Funktion eines Schnapphakens. Zu diesem Zweck ist an dem Blockierelement 45 eine Blockiernase 55 ausgebildet, die in der in den Figuren 1 und 2 dargestellten Blockierstellung des Blockierelements 45 in die Rastausnehmung 22 eingreift.The two legs 51, 52 are each arranged at an angle of about 135 degrees to the base 50. The ends of the legs 51, 52 are supported on the insert 24. The base 50 is located on the first contact ment 41. On the base 50 side facing away from the first contact element 41, the blocking element 45 is arranged. The blocking element 45 may but need not be in abutment with the first contact element 41. The blocking element 45 is integrally connected to the insert 24 and has the function of a snap-action hook. For this purpose, a blocking lug 55 is formed on the blocking element 45, which engages in the latching recess 22 in the blocking position of the blocking element 45 shown in FIGS. 1 and 2.
Die Blockiernase 55 und das Blockierelement 45 sind so ausgebildet, dass der Einsatz 24 nicht aus dem Gehäuse 5 entfernt werden kann, solange sich das Blockierelement 45 in seiner Blockierstellung befindet. Gemäß einem wesentlichen Aspekt der Erfindung verhindert der teilweise in dem Aufnahmeraum 40 angeordnete Erdschlussstift 41 , dass das Blockierelement 45 aus der dargestellten Blockierstellung in eine Lösestellung be- wegt wird. Wenn der Erdschlussstift 41 aus dem Aufnahmeraum 40 herausgezogen wird, dann kann das Blockierelement 45 aus der dargestellten Blockierstellung zu dem Einsatz 24 hin, das heißt in Figur 2 nach oben, bewegt werden, um in seine Lösestellung zu gelangen. In der (nicht dargestellten) Lösestellung des Blockierelements 45 wird die Blockiernase 55 aus der Rastausnehmung 22 heraus bewegt, so dass der Einsatz 24 aus dem Gehäuse 5 herausgezogen werden kann.The blocking lug 55 and the blocking element 45 are designed so that the insert 24 can not be removed from the housing 5 as long as the blocking element 45 is in its blocking position. According to one essential aspect of the invention, the ground fault pin 41, which is partially arranged in the receiving space 40, prevents the blocking element 45 from being moved from the illustrated blocking position into a release position. If the ground fault pin 41 is pulled out of the receiving space 40, then the blocking element 45 can be moved from the blocking position shown toward the insert 24, that is to say in FIG. 2, to reach its release position. In the (not shown) release position of the blocking element 45, the blocking lug 55 is moved out of the latching recess 22, so that the insert 24 can be pulled out of the housing 5.
Zum Lösen des Blockierelements 45 ist dieses mit einem Montagekopf 60 ausgestattet, der einstückig mit der Blockiernase 55 verbunden ist. An dem Montagekopf 60 ist eine Angriffsfläche 61 für ein Montagewerkzeug, wie einen Schraubenzieher, vorgesehen. Zwischen der Angriffsfläche 61 und der Gehäusewand 18 ist ein Montagespalt 62 vorgesehen, der den Zugang zu der Angriffsfläche 61 ermöglicht, wenn die Spule 3 und die Dichtung 4 nicht mehr mit dem elektrischen Steckverbinder 1 verbunden sind. In Figur 3 sieht man, dass in der Gehäusewand 18 eine weitere Rastaus- nehmung 63 vorgesehen ist. Die verschiedenen Rastausnehmungen 21 , 22, 63 ermöglichen es, den Einsatz 24 in unterschiedlichen Lagen in dem Gehäuse 5 anzuordnen. Vorzugsweise sind vier Rastausnehmungen vor- 5 gesehen, und zwar jeweils eine an jeder Seite des Gehäusegrundkörpers 6. Dadurch wird erreicht, dass der Einsatz 24 in Stufen von 90 Grad in dem Gehäuse 5 montiert werden kann. Das hat den Vorteil, dass das Ka- belverschraubungselement 9 in vier verschiedene Richtungen zeigen kann, und zwar aufwärts, abwärts, nach rechts oder nach links, je nach-0 dem was zweckmäßig ist.To release the blocking element 45, this is equipped with a mounting head 60, which is integrally connected to the blocking lug 55. On the mounting head 60, an engagement surface 61 for an assembly tool, such as a screwdriver, is provided. Between the engagement surface 61 and the housing wall 18, a mounting gap 62 is provided which allows access to the engagement surface 61 when the coil 3 and the seal 4 are no longer connected to the electrical connector 1. FIG. 3 shows that a further latching recess 63 is provided in the housing wall 18. The various recesses 21, 22, 63 make it possible to arrange the insert 24 in different positions in the housing 5. Preferably, four latching recesses are seen 5 before, one on each side of the housing body 6. This ensures that the insert 24 can be mounted in steps of 90 degrees in the housing 5. This has the advantage that the cable gland element 9 can point in four different directions, upwards, downwards, to the right or to the left, depending on what is expedient.
In Figur 3 sieht man des Weiteren, dass der Einsatz 24 zwei weitere Aufnahmeräume 71 , 72 aufweist, deren Öffnungen benachbart zu dem zentralen Durchgangsloch 26 in der der Spule zugewandten Stirnfläche des Einsatzes 24 angeordnet sind. Die weiteren Aufnahmeräume 71 , 72 die-5 nen zur Aufnahme von weiteren Kontaktelementen, insbesondere von Fasenstiften. Die (nicht dargestellten) Fasenstifte gehen von der Spule aus und stehen im Inneren des Einsatzes 24 mit weiteren Kontaktelementen in Verbindung.FIG. 3 further shows that the insert 24 has two further receiving spaces 71, 72, whose openings are arranged adjacent to the central through-hole 26 in the end face of the insert 24 facing the coil. The further receiving spaces 71, 72 den-5 NEN for receiving further contact elements, in particular chamfering pins. The chamfering pins (not shown) extend from the spool and communicate with other contact elements in the interior of the insert 24.
Beim Zusammenbau des elektrischen Steckverbinders 1 wird der Einsatz 0 24 in das Gehäuse 5 eingeschoben. Dabei greift die Blockiernase 55 desWhen assembling the electrical connector 1, the insert 0 24 is inserted into the housing 5. The blocking nose 55 of the
Blockierelements 45 in eine der Rastausnehmungen 21 , 22, 63 ein. Zum Entfernen des Einsatzes 24 kann das Blockierelement 45, zum Beispiel mit einem Schraubenzieher, aus der zugehörigen Rastausnehmung gehoben werden. Zum Anschließen von Leitungen an die Kontaktelemente in5 dem Einsatz 24 ist es erforderlich, den Einsatz 24 aus dem Gehäuse 5 herauszunehmen.Blocking element 45 in one of the recesses 21, 22, 63 a. To remove the insert 24, the blocking element 45, for example, with a screwdriver, be lifted from the associated recess. To connect leads to the contact elements in the insert 24, it is necessary to remove the insert 24 from the housing 5.
Gemäß einem wesentlichen Aspekt der Erfindung wird ein Herausnehmen des Einsatzes 24 durch das Blockierelement verhindert, wenn das erste Kontaktelement 41 in dem Aufnahmeraum 40 angeordnet ist, wie es in o Figur 2 gezeigt ist. Dadurch wird sicher verhindert, dass der Einsatz 24 irrtümlich aus dem Gehäuse 5 entfernt wird, bevor die Stromverbindung unterbrochen ist. Da das erste Kontaktelement 41 etwas länger, das heißt etwa 2 mm, als die beiden weiteren Kontaktelemente ist, wird der Einsatz 24 mit Hilfe des Blockierelements 45 solange in dem Gehäuse 5 fixiert, bis die weiteren Kontaktelemente keinen Kontakt mehr mit ihren zugehörigen Kontaktelementen haben. Durch das Blockierelement 45 wird verhindert, dass stromführende Teile unabsichtlich berührt werden. According to an essential aspect of the invention, removal of the insert 24 is prevented by the blocking element when the first contact element 41 is arranged in the receiving space 40, as shown in o Figure 2. This reliably prevents the insert 24 is erroneously removed from the housing 5, before the power connection is interrupted. Since the first contact element 41 is slightly longer, that is about 2 mm, than the other two contact elements, the insert 24 is fixed in the housing 5 by means of the blocking element 45 until the further contact elements no longer have any contact with their associated contact elements. The blocking element 45 prevents current-carrying parts from being touched unintentionally.
