Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Verbindungsvorrichtung für Zündanlagen von Kraftfahrzeugen nach der Gattung des Anspruchs 1. Eine solche Verbindungsanordnung ist durch die DE 36 09 475 A1 bekannt. Der dort zur Kontaktierung mit dem Anschluß einer Zündvorrichtung vorgesehene Anschlußstecker weist einen Zündkabelstecker und eine Ummantelung auf, die den Zündkabelstecker teilweise umgibt und der ein als Anschlußschuh bezeichnetes Anschlußteil zur Fixierung des Zündkabels über dessen Isolationsmantel aufweist.The invention relates to a connection device for ignition systems of motor vehicles according to the preamble of claim 1. Such a connection arrangement is known from DE 36 09 475 A1. The connector provided there for contacting the connection of an ignition device has an ignition cable connector and a sheathing which partially surrounds the ignition cable connector and which has a connection part, referred to as a connecting shoe, for fixing the ignition cable over its insulation jacket.

Als weiteren Teil des Zündkabelsteckers ist ein Anschlußstift als elektrisches Verbindungsstück zwischen dem Leiter des Zündkabels und einem weiteren Teil des Zündkabelsteckers, das als vorspringender Bereich bezeichnet ist und die Funktion eines Kontaktteils zum Anschluß an der Zündvorrichtung hat, enthalten.As a further part of the ignition cable connector, a connection pin is included as an electrical connecting piece between the conductor of the ignition cable and a further part of the ignition cable connector, which is designated as a projecting area and has the function of a contact part for connection to the ignition device.

Die Ummantelung aus einem elastischen elektrischen Isolationsstoff ist um den Zündkabelstecker herum gespritzt oder nachträglich auf ihm montiert.The sheathing made of an elastic electrical insulation material is injection molded around the ignition cable connector or subsequently mounted on it.

Zur Kopplung des Anschlußsteckers mit dem Anschluß der Zündvorrichtung ist es erforderlich, Anschlußstecker und Anschluß achsgleich zu positionieren und gerichtet zusammenzustecken.To couple the connector to the ignition device, it is necessary to position the connector and connector in the same axis and to plug them together in a directed manner.

Eine solchermaßen ausgebildete Verbindungsvorrichtung ist nur zeitaufwendig koppelbar; sie enthält als wesentlichen Teil einen Anschlußstecker, der aus vielen Teilen zusammengesetzt ist, so daß ein hoher Herstell- und Montageaufwand erforderlich ist und die Verbindungsvorrichtung nur kostenintensiv zu verwirklichen ist.A connecting device designed in this way can only be coupled in a time-consuming manner; it contains as an essential part a connector plug, which is composed of many parts, so that a high manufacturing and assembly effort is required and the connecting device can only be realized cost-effectively.

Vorteile der ErfindungAdvantages of the invention

Die erfindungsgemäße Verbindungsvorrichtung für Zündanlagen von Kraftfahrzeugen hat demgegenüber den Vorteil, daß die zuvor erwähnte Unzulänglichkeit vermieden wird. Dazu ist der Anschlußstecker der Verbindungsvorrichtung nur aus zwei Teilen, der Ummantelung und dem einteiligen Zündkabelstecker zusammengesetzt, wobei an dem Zündkabelstecker sowohl der Isolationsmantel als auch der Leiter des Zündkabels gleichartig angeschlossen werden kann und die Lagezuordnung der Ummantelung zu dem Zündkabelstecker über einen Preßsitz der Ummantelung auf dem Zündkabel erfolgt.The connection device for ignition systems of motor vehicles according to the invention has the advantage that the aforementioned inadequacy is avoided. For this purpose, the connector of the connecting device is composed of only two parts, the jacket and the one-piece ignition cable connector, both the insulation jacket and the conductor of the ignition cable can be connected in the same way to the ignition cable connector and the position assignment of the jacket to the ignition cable connector via an interference fit of the jacket the ignition cable.

Durch das den Anschluß umgebende Führungselement ist ein Aufstecken des Anschlußsteckers auch bei nicht fluchtender Anordnung zum Anschluß möglich. Mit der unmittelbaren Fixierung der Ummantelung auf dem Zündkabel muß diese in der innenliegenden Kontur nicht dem stufigen Verlauf des Zündkabelsteckers angepaßt werden, sondern nur eine einfach herzustellende Ausnehmung aufweisen.The guide element surrounding the connection enables the connector to be plugged on even when the arrangement for connection is not in alignment. With the immediate fixation of the sheath on the ignition cable, the inner contour does not have to be adapted to the stepped course of the ignition cable plug, but only has a recess that is easy to produce.

Eine derart ausgebildete Verbindungsvorrichtung ist kostengünstig herstellbar und ermöglicht auch unter grobtoleranten Fügebedingungen kurze Montagezeiten.A connecting device designed in this way is inexpensive to manufacture and enables short assembly times even under roughly tolerant joining conditions.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in Schnittdarstellungen gezeigt und in der Figurenbeschreibung näher erläutert. Es zeigt die Figur 1 den Anschlußstecker der Verbindungsvorrichtung, die Figur 2 das Zusammenfügen der Verbindungsvorrichtung bei nicht fluchtender Anordnung zwischen Anschluß und Anschlußstecker und Figur 3 eine zusammengefügte Verbindungsvorrichtung.An embodiment of the invention is shown in the drawing in sectional views and explained in more detail in the figure description. 1 shows the connector of the connecting device, FIG. 2 shows the joining of the connecting device in the case of a non-aligned arrangement between the connector and the connector, and FIG. 3 shows an assembled connecting device.

Beschreibung des AusführungsbeispielsDescription of the embodiment

Eine Verbindungsvorrichtung für Zündanlagen von Kraftfahrzeugen nach den Figuren 1 bis 3 zur Herstellung einer elektrischen Verbindung zwischen einem Zündkabel 11 und einer Zündvorrichtung 12 des Kraftfahrzeugs enthält folgende Hauptmerkmale: ein Anschlußstecker 13, der aus einem Zündkabelstecker 14, an den das Zündkabel 11 angeschlossen ist und aus einer Ummantelung 16 besteht sowie ein Anschluß 17 der Zündvorrichtung 12, der von einem Führungselement 18 umgeben ist.A connecting device for ignition systems of motor vehicles according to FIGS. 1 to 3 for establishing an electrical connection between an ignition cable 11 and an ignition device 12 of the motor vehicle contains the following main features: a connector plug 13 which consists of an ignition cable plug 14 to which the ignition cable 11 is connected and off there is a casing 16 and a connection 17 of the ignition device 12, which is surrounded by a guide element 18.

Der Zündkabelstecker 14 ist im wesentlichen als einteiliges Blechbiegeteil ausgebildet und weist einen U-förmig gebogenen Anschlußbereich 19 mit einem ersten Anschlußabschnitt 21 und einem zweiten Anschlußabschnitt 22 sowie einen hülsenförmigen Kontaktabschnitt 23 auf. Im Anschlußbereich 19 wird durch Crimpen, d. h. durch elastisch rückfederungsfähige Verformungen von Randabschnitten des Zündkabelsteckers 14 Verbindungen zu dem Zündkabel 11 hergestellt. In nicht näher dargestellter Weise werden dabei im ersten Anschlußabschnitt 21 erste Blechlappen 24 in einen Isolationsmantel 26 des Zündkabels 11 und im zweiten Anschlußabschnitt 22 zweite Blechlappen 27 in einen litzenförmigen Leiter 28 des Zündkabels 11 kraftschlüssig eingepreßt. Die Blechlappen 23, 26, die paarweise symmetrisch zu einer Längsachse 29 des Zündkabelsteckers 14 angeordnet sind, umschließen nach dem Crimpvorgang im wesentlichen die zugeordneten Abschnitte des Zündkabels 11.The ignition cable connector 14 is essentially designed as a one-piece bent sheet metal part and has a U-shaped bent connection area 19 with a first connection section 21 and a second connection section 22 and a sleeve-shaped contact section 23. In the connection area 19, connections to the ignition cable 11 are made by crimping, ie by elastically resilient deformations of edge sections of the ignition cable connector 14. In a manner not shown in detail, first sheet metal tabs 24 are pressed in a first connection section 21 into an insulation jacket 26 of the ignition cable 11 and second sheet tabs 27 in the second connection section 22 into a stranded conductor 28 of the ignition cable 11. The metal tabs 23, 26, which are arranged in pairs symmetrically to a longitudinal axis 29 of the ignition cable connector 14, essentially enclose the assigned sections of the ignition cable 11 after the crimping process.

Der Kontaktabschnitt 23, der sich an den zweiten Anschlußabschnitt 22 anschließt, weist an seinem freien Ende eine Anschlußöffnung 31 auf, die umfangsseitig von einer Wandung 32 begrenzt ist. Über einen Teil des Umfangs ist die Wandung 32 von einem, rechtwinklig zur Längsachse 29 des Zündkabelsteckers 14 gerichteten Schlitz 33 durchtrennt. In diesem ist ein Rastverbindungselement 34 in Form einer umfangsseitig auffederungsfähigen Bügelfeder gelagert und dabei durch, aus der Wandung 32 heraustretenden Rastwarzen 36 gegen axiales Abstreifen gesichert. Im Bereich des Schlitzes 33 ragt das Rastverbindungselement 34 mit einem Teil seiner Umfangserstreckung in den Kontaktabschnitt 23 hinein.The contact section 23, which adjoins the second connection section 22, has at its free end a connection opening 31 which is delimited on the circumference by a wall 32. Over part of the circumference, the wall 32 is severed by a slot 33, which is directed at right angles to the longitudinal axis 29 of the ignition cable connector 14. In this, a latching connection element 34 is mounted in the form of a spring clip which is capable of springing up on the circumferential side and is thereby secured against axial stripping by latching projections 36 emerging from the wall 32. In the area of the slot 33, the latching connection element 34 projects into the contact section 23 with part of its circumferential extent.

Die Ummantelung 16 ist aus Gummi oder einem anderen elastischen Material gefertigt und hat annähernd die Form eines Kreiszylinders mit einer gestuften, axial verlaufenden Durchgangsbohrung 37. Der radial engere Teil der Durchgangsbohrung 37 ist in seinem Durchmesser so bemessen, daß er nur mit starker Aufweitung unter Einsatz eines Gleitmittels auf den Isolationsmantel 26 des Zündkabels 11 aufgebracht werden kann. Durch die Rückfederungskräfte des aufgeweiteten Teils der Ummantelung nach aufgehobener Aufweitung und dem Ausdampfen des Gleitmittels ist die Ummantelung 16 in nicht mehr verschiebbarer Weise in einer vorbestimmten Stellung auf dem Zündkabel 11 gelagert.The casing 16 is made of rubber or another elastic material and has approximately the shape of a circular cylinder with a stepped, axially extending through hole 37. The radially narrower part of the through hole 37 is dimensioned in such a way that it is only used with a large expansion a lubricant can be applied to the insulation jacket 26 of the ignition cable 11. Due to the resilience of the expanded part of the sheathing after the expansion has ceased and the lubricant has evaporated, the sheathing 16 is mounted in a predetermined position on the ignition cable 11 in a manner that can no longer be displaced.

Der radial weitere Teil der Durchgangsbohrung 37 weist einen Durchmesser auf, der das Aufschieben des im wesentlichen durch Ummantelung 16 und Zündkabelstecker 14 gebildeten Anschlußsteckers 13 auf das den Anschluß 17 der Zündvorrichtung koaxial umgebende und dessen freies Ende überragende Führungselement 18, das in der Art einer domförmigen Steckeraufnahme ausgebildet ist, ermöglicht. Dieser Teil der Durchgangsbohrung 37 umgibt mit einem hohlzylinderförmigen Zwischenraum 38 im wesentlichen den Anschlußbereich 19 und den Kontaktabschnitt 23.The radially further part of the through-bore 37 has a diameter which pushes the connector plug 13 essentially formed by the sheath 16 and the ignition cable connector 14 onto the connector 17 coaxially surrounding the connector 17 and projecting beyond its free end Guide element 18, which is designed in the manner of a dome-shaped connector receptacle. This part of the through bore 37 essentially surrounds the connection region 19 and the contact section 23 with a hollow cylindrical intermediate space 38.

Der Anschluß 17 ist als ein symmetrisch zu einer Achse 39 angeordneter, aus der Zündvorrichtung 12 ragender Rundbolzen ausgebildet. Er weist einen im Durchmesser konstanten, in den Kontaktabschnitt 23 einfügbaren Schaft 41, eine den Schaft 41 teilende umlaufende Rastnut 42 und an seinem freien Ende eine Kuppe 43 auf.The connection 17 is designed as a round bolt which is arranged symmetrically to an axis 39 and protrudes from the ignition device 12. It has a shaft 41 which is constant in diameter and can be inserted into the contact section 23, a circumferential locking groove 42 which divides the shaft 41 and a tip 43 at its free end.

Zur Kopplung des Anschlußsteckers 13 mit dem Anschluß 17 wird in einem ersten Bewegungsschritt die Ummantelung 16 mit ihrem, dem Kontaktabschnitt 23 benachbarten offenen Ende auf das Führungselement 18 aufgeschoben, bis die Anschlußöffnung 31 des Kontaktabschnitts 23 an der Kuppe 43 angelangt ist.To couple the connector 13 to the connector 17, the casing 16 is pushed with its open end adjacent to the contact section 23 onto the guide element 18 in a first movement step until the connection opening 31 of the contact section 23 has reached the crest 43.

Liegt in dieser Stellung, die in Figur 2 dargestellt ist, ein Winkelversatz zwischen der Längsachse 29 des Zündkabelsteckers 14 und der Achse 39 des Anschlusses 17 vor, so ist dessen ungeachtet eine selbstfindende Kopplungsstellung zwischen Zündkabelstecker 14 und Anschluß 17 vorhanden. Dies ist durch die lichte Weite des Führungselements 18 bedingt, die so bemessen ist, daß der Kontaktabschnitt 23 des Zündkabelsteckers 14 an zwei zueinander versetzt liegenden Punkten seiner äußeren Begrenzung an zugeordneten Punkten der inneren Begrenzung des Führungselements 18 anstößt, dadurch die Schräglage des Zündkabelsteckers 14 begrenzt wird und in dieser Lagezuordnung der größere Teil der Kuppe 43 an der Anschlußöffnung 31 anliegt, so daß bei einem weitergeführten zweiten Bewegungsschritt der Kontaktabschnitt 23 über die Kuppe 43 auf den Schaft 41 aufgleitet, bis das Rastverbindungselement 34 in die Rastnut 42 einrastet, wie in der Figur 3 dargestellt. Für eine unlösbare Verbindungsvorrichtung ist die Querschnittsfläche der Rastnut 42 rechteckförmig, für eine alternative lösbare Verbindungsvorrichtung hingegen, vom Nutgrund aus sich erweiternd, trapezförmig.If in this position, which is shown in FIG. 2, there is an angular offset between the longitudinal axis 29 of the ignition cable connector 14 and the axis 39 of the connection 17, a self-finding coupling position between the ignition cable connector 14 and connection 17 is nevertheless present. This is due to the clear width of the guide element 18, which is dimensioned such that the contact section 23 of the ignition cable connector 14 abuts two mutually offset points of its outer boundary at associated points of the inner boundary of the guide element 18, thereby limiting the inclined position of the ignition cable connector 14 is and in this position assignment, the larger part of the crest 43 abuts the connection opening 31, so that in a continued second movement step the contact section 23 slides over the crest 43 onto the shaft 41 until the latching connection element 34 snaps into the latching groove 42, as in FIG Figure 3 shown. For a permanent connection device the cross-sectional area of the locking groove 42 is rectangular, however, for an alternative releasable connecting device, widening from the groove base, trapezoidal.

Mit der beschriebenen Verbindungsvorrichtung ist es möglich, ein Zündkabel 11 in einem Zündkabelstecker 14 sowohl am Isolationsmantel 26 als auch am Leiter 28 gleichartig zu fixieren, über das Zündkabel 11 eine Lagezuordnung zwischen der Ummantelung 16 und dem Zündkabelstecker 14 und damit einen einfach aufgebauten, kostengünstigen Anschlußstecker 13 herzustellen, dessen Kopplung mit dem Anschluß 17 der Zündvorrichtung 12 zwangszentriert erfolgt, so daß die Verbindungsvorrichtung unter grobtoleranten Fügebedingungen mit kurzen Montagezeiten herstellbar ist.With the connecting device described, it is possible to fix an ignition cable 11 in an ignition cable connector 14 to both the insulation jacket 26 and the conductor 28 in the same way, via the ignition cable 11 a position assignment between the jacket 16 and the ignition cable connector 14 and thus a simply constructed, inexpensive connector 13 to produce, the coupling with the connection 17 of the ignition device 12 is force-centered, so that the connecting device can be produced under roughly tolerant joining conditions with short assembly times.
