Description

Die Erfindung betrifft einen Steckverbinder für eine Glühkerze einer Dieselbrennkraftmaschine gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a connector for a glow plug of a diesel internal combustion engine according to the features of the preamble of claim 1.

Aus der DE 10 2004 002 905.9 ist ein Steckverbinder für eine Glühkerze einer Dieselbrennkraftmaschine in Rundbauweise bekannt. Dieser Steckverbinder ist zum Aufstecken auf eine Glühkerze einer Dieselbrennkraftmaschine ausgebildet, wobei beide mehrere zusammenbringbare elektrische Kontaktbereiche aufweisen. Über diese Kontaktbereiche wird einerseits eine Kontaktierung zur Stromversorgung der Glühkerze zum Vorglühen der Dieselbrennkraftmaschine hergestellt und andererseits eine Kontaktierung zu zumindest einem Sensor, der innerhalb der Glühkerze angeordnet ist, hergestellt. Die Sensorsignale, die im Bereich der Glühkerze erfasst werden, können in einem nachgeschalteten Steuergerät ausgewertet und zur Steuerung der Betriebsparameter der Dieselbrennkraftmaschine herangezogen werden. Die Ausbildung eines solchen Steckverbinders für eine Glühkerze mit Sensormitteln hat den Vorteil, dass sich am Einbauort in der Dieselbrennkraftmaschine eine kompakte Bauweise ergibt, so dass die aus Steckverbinder, Glühkerze und Sensormitteln bestehende Einheit wenig Platz in bzw. an der Dieselbrennkraftmaschine beansprucht. Die Erfassung von Parametern im Bereich der Glühkerze hat den Vorteil, dass die Verbrennung innerhalb der Dieselbrennkraftmaschine wesentlich besser gesteuert bzw. geregelt werden kann als bisher, so dass Abgasemissionen, Geräuschemissionen und dergleichen der Dieselbrennkraftmaschine verringert werden können, um insbesondere verschärfte Umweltvorschriften seitens Gesetzgeber einhalten zu können. Für diesen Fall ist es besonders wichtig, dass die Sensorsignale von der Glühkerze über den Steckverbinder an das nachgeschaltete Steuergerät übertragen werden.From the DE 10 2004 002 905.9 is a connector for a glow plug of a diesel engine in rotary design known. This connector is designed to be plugged onto a glow plug of a diesel internal combustion engine, wherein both have a plurality of engageable electrical contact areas. On the one hand a contact for the power supply of the glow plug for preheating the diesel engine is made via these contact areas and on the other hand a contact to at least one sensor, which is arranged within the glow plug made. The sensor signals which are detected in the region of the glow plug can be evaluated in a downstream control unit and used to control the operating parameters of the diesel internal combustion engine. The formation of such a connector for a glow plug with sensor means has the advantage that results in a compact design at the installation in the diesel engine, so that the connector, glow plug and sensor means existing unit takes up little space in or on the diesel engine. The detection of parameters in the area of the glow plug has the advantage that combustion within the diesel internal combustion engine can be controlled much better than before, so that exhaust emissions, noise emissions and the like of the diesel engine can be reduced to comply in particular stricter environmental legislation by legislators can. In this case, it is particularly important that the sensor signals are transmitted from the glow plug via the connector to the downstream control unit.

Diese Einheit unterliegt äußerst hohen Beanspruchungen, insbesondere Temperaturschwankungen und Vibrationen im Bereich der Dieselbrennkraftmaschine, insbesondere dann, wenn diese in einem Fahrzeug angeordnet ist. Hier sind Temperaturschwankungen von -40 °C bis +150 °C keine Seltenheit, wobei weitere Belastungen wie Feuchtigkeit, Spritzwasser, Schmutzpartikel und dergleichen noch hinzukommen. Daher ist es von besonderer Bedeutung, dass der Steckverbinder einerseits schnell und einfach auf die Glühkerze aufgesteckt werden kann, wozu der Steckverbinder in Rundbauweise ausgeführt ist. Andererseits ist es erforderlich, dass der Steckverbinder lagekorrekt auf die Glühkerze aufgesteckt wird, um die mehreren Kontaktbereiche zwischen Steckverbinder und Glühkerze elektrisch miteinander zu kontaktieren. Abschließend ist es wichtig, dass dann, wenn der Steckverbinder lagekorrekt auf die Glühkerze aufgesteckt worden ist, diese Steckverbindung den geschilderten Umweltbedingungen standhält und sich auf Grund dieser Umweltbedingungen der Steckverbinder nicht von der Glühkerze lösen kann.This unit is subject to extremely high stresses, in particular temperature fluctuations and vibrations in the diesel engine, especially when it is arranged in a vehicle. Here, temperature fluctuations of -40 ° C to +150 ° C are not uncommon, with further loads such as moisture, water spray, dirt particles and the like added. Therefore, it is of particular importance that the connector on the one hand can be quickly and easily plugged onto the glow plug, including the connector is designed in a round design. On the other hand, it is necessary that the connector is correctly positioned plugged onto the glow plug to electrically contact the plurality of contact areas between the connector and the glow plug. Finally, it is important that when the connector has been correctly positioned on the glow plug, this connector can withstand the environmental conditions described and due to these environmental conditions, the connector can not be detached from the glow plug.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Steckverbinder zum Aufstecken auf eine Glühkerze einer Dieselbrennkraftmaschine bereitzustellen, der die eingangs genannten Anforderungen erfüllt.The invention is therefore based on the object to provide a connector for plugging on a glow plug of a diesel internal combustion engine, which meets the requirements mentioned above.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß ist vorgesehen, dass der Steckverbinder Primärverriegelungsmittel aufweist, um den Steckverbinder nach dem Aufstecken auf die Glühkerze auf dieser in dieser Lage zu fixieren, und weiterhin Sekundärverriegelungsmittel auf dieser in dieser Lage zu fixieren und weiterhin Sekundärverriegelungsmittel (CPA) aufweist, um die Primärverriegelungsmittel in ihrer erreichten Lage zu fixieren. Die Primärverriegelungsmittel bewirken also, dass der Steckverbinder nach dem Aufstecken auf die Glühkerze in dieser Lage, in der die Kontaktbereiche zwischen Steckverbinder und Glühkerze kontaktiert worden sind, in seiner Lage fixiert wird. Da auf Grund der rauen Umweltbedingungen und Einsatzbedingungen, insbesondere Vibrationen im Bereich der Dieselbrennkraftmaschine, trotz dieser Primärverriegelung noch die Gefahr besteht, dass sich die Primärverriegelungsmittel aus ihrer erreichten Position herausbewegen (und damit ein Lösen des Steckverbinders von der Glühkerze ermöglicht würde), ist in vorteilhafter Weise vorgesehen, dass die Primärverriegelungsmittel durch die Sekundärverriegelungsmittel zusätzlich gesichert werden. Dies erfolgt in vorteilhafter Weise durch eine Rastverbindung, die es ermöglicht, im Reparaturfalle den Steckverbinder von der Glühkerze lösen zu können. Hierbei ist allerdings eine Konstruktion und Abstimmung der Primär- und Sekundärverriegelungsmittel aufeinander in der Art und Weise erforderlich, dass zum Lösen der Verriegelungsmittel so hohe Kräfte erforderlich sind (insbesondere beim Lösen der Sekundärverriegelungsmittel), die beim Betrieb der Dieselbrennkraftmaschine nicht vorkommen. An dieser Stelle kann also daran gedacht werden, die Sekundärverriegelungsmittel bzw. deren Verriegelungskräfte so zu wählen, dass sie einerseits den beim Betrieb der Dieselbrennkraftmaschine auftretenden Kräften widerstehen, aber andererseits durch Aufbringung höherer Kräfte (beispielsweise mittels eines Werkzeuges) wieder in ihre Ausgangsposition (endverriegelte Position) gebracht werden können.According to the invention, the connector has primary locking means in order to fix the plug connector in this position after being placed on the glow plug, and furthermore to fix secondary locking means thereon in this position and furthermore has secondary locking means (CPA) to hold the primary locking means in its position reached position to fix. The primary locking means thus cause the connector after being placed on the glow plug in this position, in which the contact areas between the connector and glow plug have been contacted, is fixed in position. Because of the harsh environmental conditions and conditions of use, in particular vibrations in the diesel engine, despite this primary locking, there is still the risk that the primary locking means move out of their position reached (and thus a release of the connector would allow the glow plug), is provided in an advantageous manner that the primary locking means are additionally secured by the secondary locking means. This is done in an advantageous manner by a latching connection, which makes it possible to solve the connector of the glow plug in the event of a repair can. In this case, however, a construction and coordination of the primary and secondary locking means successive in the manner required to release the locking means so high forces are required (especially when releasing the secondary locking means), which do not occur during operation of the diesel engine. At this point, it can therefore be thought to choose the secondary locking means or their locking forces so that they withstand the forces occurring during operation of the diesel engine on the one hand, but on the other hand by applying higher forces (for example by means of a tool) back to their original position (end locked position ) can be brought.

In Weiterbildung der Erfindung sind die Verriegelungsmittel, also entweder die Sekundärverriegelungsmittel und/oder die Primärverriegelungsmittel, mittels einer Längsbewegung und/oder einer Drehbewegung von ihrer ersten Position (noch nicht verriegelt) in die zumindest weitere Position (insbesondere verriegelt) bringbar sind. In besonders vorteilhafter Weise erfolgt die Verriegelung der Verriegelungsmittel bei beiden mittels einer Längsbewegung, wobei die Verriegelungsmittel so gestaltet sind, dass beim Verriegeln des Steckverbinders auf der Glühkerze zunächst die Primärverriegelungsmittel von der ersten in die zumindest weitere Position bringbar sind (und währenddessen die Sekundärverriegelungsmittel diese Bewegung mitmachen) und erst dann eine Längsbewegung der Sekundärverriegelungsmittel von deren erster Position in zumindest eine weitere Position möglich wird, wenn die Primärverriegelungsmittel ihre zumindest weitere Position (insbesondere Endposition) erreicht haben.In a further development of the invention, the locking means, so either the secondary locking means and / or the primary locking means, by means of a longitudinal movement and / or rotational movement from its first position (not yet locked) in the at least another position (in particular locked) can be brought. In a particularly advantageous manner, the locking of the locking means takes place in both by means of a longitudinal movement, wherein the locking means are designed so that when locking the connector on the glow plug first, the primary locking means of the first in the at least further position can be brought (and meanwhile the secondary locking means this movement join in) and only then is a longitudinal movement of the secondary locking means from its first position into at least one further position becomes possible, when the primary locking means have reached their at least further position (in particular end position).

Figur 2 zeigt den Steckverbinder 1 und die Glühkerze 2 im Schnitt gemäß Figur 1. Im oberen Teil der Figur 2 ist der Steckverbinder 1 im Schnitt dargestellt, wobei mehrere, insbesondere drei Kontaktbereiche 3 bis 5 zu erkennen sind. Diese Kontaktbereiche 3 bis 5 sind beispielsweise als Lamellenkontakte ausgebildet, wobei andere Ausführungen denkbar sind. Weiterhin weist der Steckverbinder 1 eine feststehende Gehäusehülse 6 auf, an deren Ende eine Gehäusekappe 7 angeordnet ist, die den kabelseitigen Abgangsbereich des Steckverbinders 1 bildet. Weiterhin sind hier längsbewegbare Primärverriegelungsmittel 8 und ebenfalls längsbewegbare Sekundärverriegelungsmittel 9 vorhanden. Im nicht aufgesteckten Zustand des Steckverbinders 1 befinden sich beide Verriegelungsmittel 8, 9 jeweils in einer ersten Position (Ausgangsposition) die nach dem Herstellen bzw. dem Zusammenbau des Steckverbinders 1 eingenommen wird. In besonders vorteilhafter Weise sind hierzu die Verriegelungsmittel 8, 9 derart gestaltet, dass sie diese erste Position so lange beibehalten und aus dieser Position so lange nicht herausbewegt werden können, bis der Steckverbinder 1 auf die Glühkerze 2 aufgesteckt wurde.FIG. 2 shows the plug connector 1 and the glow plug 2 in section according to FIG. 1. In the upper part of FIG. 2, the plug connector 1 is shown in section, wherein several, in particular three contact areas 3 to 5 can be seen. These contact areas 3 to 5 are formed, for example, as lamellar contacts, with other designs are conceivable. Furthermore, the connector 1 has a fixed housing sleeve 6, at the end of a housing cap 7 is arranged, which forms the cable-side outlet region of the connector 1. Furthermore, here longitudinally movable primary locking means 8 and also longitudinally movable secondary locking means 9 are present. When not plugged in the connector 1, both locking means 8, 9 are each in a first position (initial position) which is taken after the manufacture or assembly of the connector 1. In a particularly advantageous manner, the locking means 8, 9 are designed for this purpose so that they can maintain this first position as long and can not be moved out of this position until the connector 1 has been plugged onto the glow plug 2.

Der untere Teil der Figur 2 zeigt den Steckverbinder 1, nachdem er auf die Glühkerze 2 aufgesteckt wurde. In dieser Darstellung befinden sich die Verriegelungsmittel 8, 9 beide noch in ihrer ersten Position, wobei Positionsveränderung und die daraus resultierende Verriegelung des Steckverbinders 1 auf der Glühkerze 2 im Folgenden beschrieben wird.The lower part of Figure 2 shows the connector 1 after it has been plugged onto the glow plug 2. In this illustration, the locking means 8, 9 are both still in their first position, wherein change in position and the resulting locking of the connector 1 on the glow plug 2 will be described below.

Figur 3 zeigt eine Ausführungsmöglichkeit der Primär- und Sekundärverriegelungsmittel 8, 9 sowie deren Wirkungsweise. Im oberen Teil der Figur 3 ist der Verriegelungsablauf a) bis d) der Primärverriegelungsmittel 8 gezeigt, während im unteren Teil der Figur 3 der Verriegelungsablauf der Sekundärverriegelungsmittel in den Schritten e) bis h) gezeigt ist. Allerdings laufen diese Abläufe a) bis d) sowie e) bis h) nicht unabhängig voneinander, sondern greifen teilweise ineinander ein.Figure 3 shows an embodiment of the primary and secondary locking means 8, 9 and their mode of action. In the upper part of Figure 3, the locking sequence a) to d) of the primary locking means 8 is shown, while in the lower part of Figure 3, the locking sequence of the secondary locking means in steps e) to h) is shown. However, these processes a) to d) and e) to h) do not run independently of each other, but partially intermesh.

Figur 3 a) zeigt, dass die Primärverriegelungsmittel 8 einen Ausleger 81 aufweisen, an dessen Ende ein Rasthaken 82 angeordnet ist. Dieser Rasthaken 82 korrespondiert im weiteren Verriegelungsverlauf mit einem Steg 24 und/oder einer Nut 25 der Glühkerze 2. Erfindungsgemäß weisen also die Primärverriegelungsmittel 8 einen an dem Ausleger 81 angeordneten Rasthaken 82 auf, wobei der Rasthaken 82 zum Zusammenwirken mit dem Steg 24 und/oder der Nut 25 der Glühkerze 2 beim Aufstecken des Steckverbinders 1 auf die Glühkerze 2 ausgebildet ist. Mit den vorbeschriebenen Mitteln wird die Primärverriegelung erzielt. Weiterhin weisen die Primärverriegelungsmittel 8 noch einen Anschlag 83 sowie einen weiteren Rasthaken 84 auf, wobei der weitere Rasthaken 84 im Bereich des Anschlages 83 angeordnet ist.Figure 3 a) shows that the primary locking means 8 have a boom 81, at the end of a latching hook 82 is arranged. According to the invention, the primary locking means 8 have a latching hook 82 arranged on the arm 81, wherein the latching hook 82 interacts with the web 24 and / or in the latching hook 82 the groove 25 of the glow plug 2 when plugging the connector 1 is formed on the glow plug 2. With the means described above, the primary locking is achieved. Furthermore, the primary locking means 8 still have a stop 83 and a further latching hook 84, wherein the further latching hook 84 is arranged in the region of the stop 83.

Die Primärverriegelung des Steckverbinders 1 auf die Glühkerze 2 erfolgt derart, dass gemäß Figur 3 a) der Kontaktbereich 23 der Glühkerze 2 in die Gehäusehülse 6 des Steckverbinders 1 mit einer Längsbewegung eingeführt wird, d.h, dass der Steckverbinder 1 auf die Glühkerze 2 aufgesteckt wird. Während dieses Einführungsvorganges gelangt der Steg 24 an den Rasthaken 82. Beim weiteren Einschieben der Glühkerze 2 in den Steckverbinder 1 wird der Rasthaken 82 von dem Steg 24 abgehoben (Figur 3 b) und greift nach weiterem Einschieben in die Nut 25 ein (Figur 3 c), wobei mittels dieses Eingriffes des Rasthakens 82 in die Nut 25 die Primärverriegelung erfolgt ist. Um die gewünschte Positionierung beim Aufsetzen des Steckverbinders 1 auf die Glühkerze 2 zu erreichen, ist der Anschlag 83 vorhanden, an dem der Steg 24 zur Anlage kommt (Figur 3 c), wenn der Steckverbinder 1 korrekt auf die Glühkerze 2 aufgesteckt worden ist.The primary locking of the connector 1 on the glow plug 2 is such that according to Figure 3 a) the contact portion 23 of the glow plug 2 is inserted into the housing sleeve 6 of the connector 1 with a longitudinal movement, that is, the connector 1 is plugged onto the glow plug 2. During this insertion process, the web 24 reaches the latch hook 82. Upon further insertion of the glow plug 2 in the connector 1, the latch hook 82 is lifted from the web 24 (Figure 3 b) and engages after further insertion into the groove 25 (Figure 3 c ), wherein by means of this engagement of the latching hook 82 in the groove 25, the primary locking is done. In order to achieve the desired positioning when placing the connector 1 on the glow plug 2, the stop 83 is present at which the web 24 comes to rest (Figure 3 c), when the connector 1 has been correctly attached to the glow plug 2.

In Figur 3 a ist erkennbar, dass die Sekundärverriegelungsmittel eine Ausnehmung 91 für den Rasthaken 82 aufweisen. In der ersten Position sowohl der Primärverriegelungsmittel 8 als der Sekundärverriegelungsmittel 9 sind Rasthaken 82 und Ausnehmung 82 und Ausnehmung 91 deckungsgleich, so dass der Rasthaken 82 beim Aufstecken des Steckverbinders 1 auf die Glühkerze 2 bei Auslenkung des Auslegers 81 in diese Ausnehmung 91 eingreifen kann (Figur 3 b) damit die Primärverriegelung mittels des Rasthakens 82 bewerkstelligt werden kann. Bei diesem Primärverriegelungsablauf von a) bis c) erfolgt keine Positionsänderung zwischen den Verriegelungsmitteln 8, 9. Die Primärverriegelungsmittel 9 weisen an ihrer äußeren Oberfläche mehrere umlaufende Stege 92 auf, was für die spätere manuelle Lageveränderung von Vorteil ist, da damit zur manuellen Lageveränderung die Sekundärverriegelungsmittel 9 besser bewegbar sind. Diese Lageveränderung ist in Figur 3 d gezeigt, bei der die Sekundärverriegelungsmittel 8 in Längsrichtung aus ihrer Position in eine weitere Position (insbesondere Endposition) gebracht worden sind. In dieser zumindest weiteren Position sind der Rasthaken 82 der Primärverriegelungsmittel 8 und die Ausnehmung 91 der Sekundärverriegelungsmittel 9 nicht mehr deckungsgleich, so dass der Ausleger 81 nicht mehr bewegbar ist, weil der Rasthaken 82 zwischen der Innenseite der Sekundärverriegelungsmittel 9 und dem Steg 25 der Glühkerze 2 eingeklemmt ist. In dieser in Figur 3 d gezeigten Position sind die Sekundärverriegelungsmittel 9 ebenfalls lösbar verrastet, wobei der Bewegungsablauf der Sekundärverriegelung und deren Verrastung anhand der Figuren 3 e) bis h) beschrieben wird.In FIG. 3 a, it can be seen that the secondary locking means have a recess 91 for the latching hook 82. In the first position of both the primary locking means 8 and the secondary locking means 9 are latching hook 82 and recess 82 and recess 91 congruent so that the latch hook 82 when plugging the connector 1 on the glow plug 2 upon deflection of the arm 81 can engage in this recess 91 (FIG 3 b) so that the primary locking be accomplished by means of the latching hook 82 can. In this primary locking sequence from a) to c), there is no change in position between the locking means 8, 9. The primary locking means 9 have on their outer surface a plurality of circumferential webs 92, which is advantageous for the later manual position change, since thus the manual Verstellveränderung the secondary locking means 9 are better movable. This change in position is shown in Figure 3 d, in which the secondary locking means 8 have been brought in the longitudinal direction of its position in a further position (in particular end position). In this at least further position of the latch hooks 82 of the primary locking means 8 and the recess 91 of the secondary locking means 9 are no longer congruent, so that the boom 81 is no longer movable, because the locking hook 82 between the inside of the secondary locking means 9 and the web 25 of the glow plug. 2 is trapped. In this position shown in Figure 3 d, the secondary locking means 9 are also releasably locked, the movement sequence of the secondary locking and their latching with reference to the figures 3 e) to h) will be described.

Zusätzlich zu den schon beschriebenen und gezeigten Elementen der Verriegelungsmittel 8, 9 weisen die Sekundärverriegelungsmittel 9 einen an einem Ausleger 93 angeordneten Rasthaken 94 auf, wobei der Rasthaken 94 zum Zusammenwirken mit dem Rasthaken 84 der Primärverriegelungsmittel 8 ausgebildet ist. Weiterhin ist an dem Ausleger 93 noch eine Erhebung 95 angeordnet, die in Richtung des Kontaktbereiches 23 der Glühkerze 2 gerichtet ist. In der jeweiligen ersten Position der Verriegelungsmittel 8, 9 greifen der Rasthaken 84 und der Rasthaken 94 ineinander ein, so dass bewirkt wird, dass die Sekundärverriegelungsmittel 9 in einer bestimmten Position zu den Primärverriegelungsmitteln 8 gehalten werden. Wenn der Steckverbinder 1 auf die Glühkerze 2 aufgesteckt wird, gleitet der Steg 24 über die Erhebung 95, so dass der Ausleger 93 ausgelenkt wird. Dies ist in Figur 3 g beschrieben. Diese Auslenkung des Auslegers 93 bewirkt zusätzlich, dass der Rasthaken 94 von Rasthaken 84 abhebt, so dass folgender Zustand erreicht ist (Figur 3 c und g):In addition to the already described and shown elements of the locking means 8, 9, the secondary locking means 9 a arranged on a boom 93 latching hooks 94, wherein the latching hook 94 is adapted to cooperate with the latching hook 84 of the primary locking means 8. Furthermore, a survey 95 is still arranged on the boom 93, which is directed in the direction of the contact region 23 of the glow plug 2. In the respective first position of the locking means 8, 9 engage the latching hook 84 and the locking hook 94 into each other, so that is causes the secondary locking means 9 are held in a certain position to the primary locking means 8. When the connector 1 is plugged onto the glow plug 2, the web 24 slides over the elevation 95, so that the boom 93 is deflected. This is described in FIG. 3 g. This deflection of the cantilever 93 additionally causes the latching hook 94 to lift off the latching hook 84, so that the following state is reached (FIGS. 3 c and g):

Der Steckverbinder 1 ist lagekorrekt auf der Glühkerze 2 aufgesteckt und die Primärverriegelung (Eingriff des Rasthakens 82 in die Nut 25 und Anlage des Steges 24 an dem Anschlag 83) ist erfolgt. (Figur 3 c). Zur zusätzlichen Verriegelung der Primärverriegelungsmittel 8 mittels der Sekundärverriegelungsmittel 9 werden diese nun von ihrer ersten Position (Figur 3 c und g) in ihre zumindest weitere Position (insbesondere Endposition) längs verschoben. Nach dieser Längsverschiebung sind die Primärverriegelungsmittel 8 dadurch verriegelt, dass die Ausnehmung 91 der Sekundärverriegelungsmittel 9 nicht mehr deckungsgleich ist mit dem Rasthaken 82 der Primärverriegelungsmittel (Figur 3 d). Die Lagefixierung (Verrastung) der Sekundärverriegelungsmittel 9 erfolgt dadurch, dass durch Auslenkung des Auslegers 93 die Rasthaken 84, 94 voneinander abgehoben sind und dadurch eine Längsverschiebung der Sekundärverriegelungsmittel 9 soweit in Richtung der Glühkerze 2 erfolgen konnte, bis die Erhebung 95 an dem Ausleger 93 ebenfalls in der Nut 25 der Glühkerze 2 zu liegen kam (s. Figur 3 h).The connector 1 is correctly positioned plugged onto the glow plug 2 and the primary lock (engagement of the latching hook 82 in the groove 25 and system of the Web 24 on the stop 83) has taken place. (Figure 3 c). For additional locking of the primary locking means 8 by means of the secondary locking means 9 they are now moved from their first position (Figure 3 c and g) in their at least another position (in particular end position) along. After this longitudinal displacement, the primary locking means 8 are locked in that the recess 91 of the secondary locking means 9 is no longer congruent with the latching hook 82 of the primary locking means (Figure 3 d). The position fixing (locking) of the secondary locking means 9 is effected in that the detent hooks 84, 94 are lifted apart by deflection of the cantilever 93 and thereby longitudinal displacement of the secondary locking means 9 could take place in the direction of the glow plug 2 until the survey 95 on the boom 93 also in the groove 25 of the glow plug 2 came to rest (see Figure 3 h).

Figur 4 zeigt eine weitere Ausgestaltung und Wirkungsweise der erfindungsgemäßen Primär- und Sekundärverriegelungsmittel, wobei Steckverbinder 1 und Glühkerze 2 lediglich um 90 Grad gedreht sind und konstruktiv geringfügig von denen gemäß Figur 3 abweichen. Die Ausgestaltung und Wirkungsweise der Verriegelungsmittel 8, 9 ist aber die gleiche.Figure 4 shows a further embodiment and operation of the primary and secondary locking means according to the invention, wherein connector 1 and glow plug 2 are rotated only by 90 degrees and slightly different from those of Figure 3 structurally. The design and operation of the locking means 8, 9 is the same.
