Description

Die Erfindung betrifft eine Verliersicherungs-Anordnung an Zündspulen für Kraftfahrzeuge nach der Gattung des Anspruchs 1, wie sie beispielsweise aus der DE 26 23 496 A1 bekannt ist. Ein Auswechseln der Zündspule erfordert ein vollständiges Abschrauben der Gewindemutter vom jeweiligen Gewindebolzen und ein entsprechendes Aufschrauben. Hierbei sind beide abgeschraubten Gewindemuttern gegen ein Verlieren nicht gesichert. Eine verlorene und nicht auffindbare Gewindemutter verursacht hierbei einen erhöhten Zeitaufwand, der bei den verhältnismäßig hohen Reparatur-Stundensätzen zu vermeiden ist.The invention relates to a captive arrangement on ignition coils for motor vehicles according to the type of claim 1 as they is known for example from DE 26 23 496 A1. A replacement the ignition coil requires a complete unscrewing of the Threaded nut from the respective threaded bolt and a corresponding one Screw on. Here both unscrewed nuts are against a loss is not guaranteed. A lost and untraceable Threaded nut causes an increased expenditure of time, which the relatively high repair hourly rates should be avoided.

Aufgabe der Erfindung ist es, die gattungsgemäße Verliersicherungs-Anordnung an Zündspulen für Kraftfahrzeuge so weiterzubilden, daß jede der die Zündspule haltende Gewindemuttern nicht verlorengehen kann.The object of the invention is the generic captive arrangement to further develop ignition coils for motor vehicles so that each the threaded nuts holding the ignition coil cannot be lost.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1 solved.

Mithin wird bei einem allfälligen Wechsel der Zündspule kein erhöhter Zeitaufwand durch das Suchen einer verlorenen Gewindemutter erforderlich. Therefore, if the ignition coil is changed, there is no increase Time spent looking for a lost nut required.  

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteran­ sprüchen beschrieben. Mit der Anordnung nach Anspruch 3 wird für einen Kabelschuh mit einer Ringöse eine technisch einfache und in der Handhabe günstige Verliersicherungs-Anordnung vorgeschlagen. Mit dem Gegenstand des Anspruchs 4 erreicht man eine Sicherung der Gewinde­ mutter gegen Lockerung am Gewindebolzen im Betriebszustand des Kraftfahrzeugs.Advantageous developments of the invention are in the Unteran sayings described. With the arrangement according to claim 3 is for a cable lug with a ring eyelet a technically simple and in the Handle proposed captive arrangement proposed. With the The subject of claim 4 achieves a backup of the thread nut against loosening of the threaded bolt in the operating state of the Motor vehicle.

Zeichnungdrawing

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge­ stellt und in der Figurenbeschreibung näher erläutert. Es zeigen je­ weils nur abschnittsweise und in vergrößerter Darstellung Fig. 1 die Ansicht des Sekundärbereiches einer Zündspule für Kraftfahrzeuge mit nur einem Kabelanschluß; und Fig. 2 die Draufsicht des Sekun­ därbereichs mit einem festgeschraubten und einem gelösten Kabelan­ schluß.An embodiment of the invention is shown in the drawing Darge and explained in more detail in the figure description. There each show weils only in sections and in enlarged representation, Figure 1 shows a view of the secondary region of an ignition coil for motor vehicles with a single cable connection. and Fig. 2 shows the top view of the secondary area with a screwed and a loosened cable connection.

Beschreibung des AusführungsbeispielesDescription of the embodiment

Die Fig. 1 und 2 zeigen von einer Zündspule für Kraftfahrzeuge deren Primärabschnitt 10 mit einer darin mittels Gußmasse ver­ gossenen, nicht dargestellten Primärwicklung, deren beiden Draht­ enden in nicht dargestellter Weise elektrischen Kontakt haben mit je einem Gewindebolzen 11. Dieser hat einen Ringbund 12 und steht von der Außenseite des Gehäuses 13 der Zündspule ab, die einen Sekundär­ abschnitt 14 mit einer innenliegenden, nicht sichtbaren Sekundär­ wicklung hat. Figs. 1 and 2 show of an ignition coil for motor vehicles with a primary portion 10 having a casting compound cast therein ver means, not shown, primary winding, the two wire ends in a manner not shown electrical contact have each with a threaded pin 11. This has an annular collar 12 and protrudes from the outside of the housing 13 of the ignition coil, which has a secondary section 14 with an internal, not visible secondary winding.

Ein nur abschnittsweise dargestelltes elektrisches Kabel 15 hat elektrischen Kontakt mit einem als Kontaktstück ausgebildeten Kabel­ schuh 16, der eine Ringöse 17 mit einem verdeckten Durchbruch auf­ weist. Von der Außenkante 18 der Ringöse 17 stehen einstückig drei Lappen 19 ab, wobei jeder Lappen 19 anfänglich parallel zum Ge­ windebolzen 11 verläuft und dessen Endabschnitt 20 zum Gewindebolzen 11 abgewinkelt ist. Eine Gewindemutter 21 hat ein nicht sichtbares, mit dem Gewindebolzen 11 zusammenwirkendes Innengewinde und einen Sechskantkopf 22 sowie eine zwischen diesem und einem Ringbund 23 angeordnete Ringnut 24. In diese greifen die Endabschnitte 20 der Lappen 19, und die Länge der Lappen 19 sowie die Breite der Ringnut 24 sind derart bemessen, daß ein Spiel zwischen der Gewindemutter 21 und dem Kabelschuh 16 vorhanden ist.An electrical cable 15 shown only in sections has electrical contact with a cable shoe 16 designed as a contact piece, which has an eyelet 17 with a hidden opening. From the outer edge 18 of the eyelet 17 integrally has three tabs 19 on each lobe 19 initially threaded bolt runs parallel to Ge 11 and its end portion is angled 20 to the threaded bolt. 11 A threaded nut 21 has an internal thread (not visible) which interacts with the threaded bolt 11 and a hexagon head 22 and an annular groove 24 arranged between the latter and an annular collar 23 . The end portions 20 of the tabs 19 engage in these, and the length of the tabs 19 and the width of the annular groove 24 are dimensioned such that there is play between the threaded nut 21 and the cable lug 16 .

Im nicht sichbaren, als Loch ausgebildeten Durchbruch der Ringöse 17 des Kabelschuhs 16 ist eine als Sicherungsscheibe ausgebildete Zahn­ scheibe 25 durch Einsprengen angeordnet, wobei deren Zähne zur Längsausdehnung des Gewindebolzens 11 schräggestellt sind.In the invisible, designed as a hole breakthrough of the ring eyelet 17 of the cable lug 16 , a toothed disk 25 designed as a locking washer is arranged by snap-in, the teeth of which are inclined to the longitudinal extension of the threaded bolt 11 .
