Abstract

The spark plug connector has an insulating part and an electric shield. The latter at least partly surrounds the insulating part. The electric shield is made of electrically conductive plastics material. The electric shield and the insulating part are preferably formed as one piece. The insulating part (14) preferably surrounds the ignition cable (16), a resistance type suppressor (18) and part of the spark plug (10). The electric shield (22) is preferably provided on the outer wall of the insulating part (14). The latter (14) is preferably also made of plastic. The two plastic parts may be connected together or formed from the same material, where only the shield (22) region is electrically conductive.

Description

Die Erfindung bezieht sich auf einen Zündkerzenstecker gemäß Oberbegriff des Anspruchs 1.The invention relates to a spark plug connector according to the preamble of claim 1.

Derartige Zündkerzenstecker besitzen eine elektrisch leitfähige Umhüllung des Isolierteiles, um insbesondere elektromagnetische Störstrahlung abzu­ schirmen und elektromagnetische Verträglichkeit im Kraftfahrzeug zu si­ chern. Dazu sind Metallhülsen vorgesehen, die das Isolierteil des Zündker­ zensteckers umgeben.Spark plug connectors of this type have an electrically conductive covering of the insulating part, in particular to reduce electromagnetic interference shield and electromagnetic compatibility in the motor vehicle to si chern. For this purpose, metal sleeves are provided, which are the insulating part of the spark plug surrounded zenstecker.

Aufgabe der Erfindung ist es, die Produktionskosten zu senken und zugleich eine zuverlässige Abschirmung des Isolierteiles des Zündkerzensteckers sicherzustellen.The object of the invention is to reduce production costs and at the same time a reliable shielding of the insulating part of the spark plug connector ensure.

Die Aufgabe wird gelöst durch den Anspruch 1.The object is achieved by claim 1.

Erfindungsgemäß ist vorgesehen, daß zumindest ein Teil der Außenwan­ dung des Zündkerzensteckers mit einem elektrisch leitfähigen Kunststoff versehen wird.According to the invention it is provided that at least part of the outer wall the spark plug connector with an electrically conductive plastic is provided.

In geeigneter Weise kann dabei die elektrisch leitfähige Außenwandung und der übrige Zündkerzenstecker, der aus einem isolierenden Kunststoff be­ steht, einstückig miteinander ausgebildet werden, indem z. B. die Außen­ wandung durch Beigaben von Kohlenstoff oder Ruß leitfähig gemacht wird.In a suitable manner, the electrically conductive outer wall and the rest of the spark plug connector, which be made of an insulating plastic stands, are integrally formed by z. B. the outside wall is made conductive by adding carbon or soot.

Im folgenden wird die Erfindung anhand der Figuren im Detail beschrieben.The invention is described in detail below with reference to the figures.

Die einzige Figur zeigt einen Querschnitt durch den erfindungsgemäßen Zündkerzenstecker. The single figure shows a cross section through the invention Spark plug connector.  

Mit dem Bezugszeichen 10 ist eine Zündkerze bezeichnet, auf die ein Ker­ zenstecker 12 aufgesteckt ist. Der Kerzenstecker 12 besitzt einen isolieren­ den Kunststoff 14, der das Zündkabel 16, einen Entstörwiderstand 18 sowie einen Teil der Zündkerze 10 umgibt.The reference numeral 10 designates a spark plug, on which a Ker zenstecker 12 is plugged. The spark plug connector 12 has an isolating plastic 14 which surrounds the ignition cable 16 , an interference suppressor 18 and part of the spark plug 10 .

Das Isolierteil 14 des Zündkerzensteckers 12 ist erfindungsgemäß an seiner Außenwandung mit einer Abschirmung 22 versehen. Diese Abschirmung 22 besteht aus leitfähigem Kunststoff und kann somit in die Isolierung 14, die ebenfalls aus Kunststoff besteht, integriert werden. In geeigneter Weise sind die beiden Kunststoffe miteinander verbunden oder bestehen sogar aus dem gleichen Material, wobei nur der Bereich 22 elektrisch leitfähig ist, bei­ spielsweise durch Pigmentierung mit Ruß, um diese Leitfähigkeit herzustel­ len.According to the invention, the insulating part 14 of the spark plug connector 12 is provided with a shield 22 on its outer wall. This shield 22 is made of conductive plastic and can thus be integrated into the insulation 14 , which is also made of plastic. In a suitable manner, the two plastics are connected to one another or even consist of the same material, only the region 22 being electrically conductive, for example by pigmenting with carbon black, in order to produce this conductivity.

Es ist jedoch auch möglich, unterschiedliche Kunststoffe vorzusehen und dabei zur besseren Unterscheidbarkeit den Materialien der Isolierung 14 und der Abschirmung 22 unterschiedliche Farben zuzuweisen.However, it is also possible to provide different plastics and to assign different colors to the materials of the insulation 14 and the shield 22 for better differentiation.

Im Bereich 24 ist ein Maßekontakt der leitenden Abschirmung mit den auf Masse liegenden Teilen der Zündkerze 10 vorgesehen.In area 24 , a ground contact of the conductive shield with the parts of the spark plug 10 that are connected to ground is provided.

Durch die Ausgestaltung der Abschirmung aus leitendem Kunststoff ist die Abschirmung in besonders kostengünstiger Weise durchzuführen, außer­ dem ist durch die innige Verbindung eine hohe Festigkeit gesichert.Due to the design of the shield made of conductive plastic Shielding in a particularly cost-effective manner, except the intimate connection ensures high strength.

Auch können Teilbereiche des Isolierteiles 14 und/oder der Abschirmung 22 mit unterschiedlicher Härte ausgebildet sein, um eine gute formschlüssige Verbindung zwischen Zündkerze 10 und Zündkerzenstecker 12 zu gewähr­ leisten.Partial areas of the insulating part 14 and / or the shield 22 can also be formed with different hardness in order to ensure a good positive connection between the spark plug 10 and the spark plug connector 12 .
