Abstract
Description
Die vorliegende Erfindung betrifft einen Kabelschuh zur elektrischen Anbindung einer Masseleitung an eine Fahrzeugkarosserie eines Kraftfahrzeuges gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem ein Kraftfahrzeug mit einer Masseleitung, die über einen derartigen Kabelschuh an die Fahrzeugkarosserie angebunden ist.The present invention relates to a cable lug for the electrical connection of a ground line to a vehicle body of a motor vehicle according to the preamble of claim 1. The invention also relates to a motor vehicle with a ground line, which is connected via such a cable lug to the vehicle body.
Gattungsgemäße Kabelschuhe sind hinreichend bekannt und werden zur Anbindung einer elektrischen Masseleitung an eine Kraftfahrzeugkarosserie in unterschiedlichsten Ausführungsformen verwendet.Generic cable lugs are well known and are used to connect an electrical grounding line to a motor vehicle body in various embodiments.
Bei einem Batterieeinbruch besteht prinzipiell die Möglichkeit, über die Batteriekontakte, das heißt über einen Minus- und einen Pluspol der Fahrzeugbatterie, diese nachzuladen bzw. Starthilfe zu leisten. Da bei einigen Kraftfahrzeugen die Batteriepole jedoch schlecht erreichbar sind, wird üblicherweise zumindest für die Masse ein separater Massefremdstartstützpunkt montiert. Hierzu wird der Massepol der Fahrzeugbatterie mit der Fahrzeugkarosserie leitend verbunden und an einer geeigneten Stelle ein Massefremdstartstützpunkt an der Fahrzeugkarosserie montiert. Dieser Massefremdstartstützpunkt wird somit durch ein separates Sonderteil realisiert. Nachteilig hierbei sind insbesondere das zusätzliche Gewicht des Massefremdstartstützpunkts, der zur Montage desselben entstehende Montageaufwand, die Disposition, eine Bereitstellung an einem Fertigungsband sowie die jeweils zugeordneten Kostenaufwendungen.In the event of a battery breakdown, it is in principle possible to recharge or jump-start the battery via the battery contacts, that is to say via a negative and a positive pole of the vehicle battery. However, since the battery poles are difficult to reach in some vehicles, a separate mass foreign launch base is usually mounted at least for the mass. For this purpose, the ground terminal of the vehicle battery is conductively connected to the vehicle body and mounted at a suitable location a mass foreign launch base on the vehicle body. This mass foreign launch base is thus realized by a separate special part. Disadvantages here are, in particular, the additional weight of the mass foreign launching point, the assembly work arising therefrom, the disposition, a provision on a production line and the respective associated cost expenditures.
Aus der
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Kabelschuh der gattungsgemäßen Art eine verbesserte Ausführungsform anzugeben, mittels welcher insbesondere die bisher separat verbauten Massefremdstartstützpunkte entfallen und dadurch Montage- und Kostenvorteile erzielt werden können.The present invention is concerned with the problem of providing an improved embodiment for a cable lug of the generic type, by means of which in particular the previously installed separately foreign launch bases omitted and thereby assembly and cost advantages can be achieved.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, an einem Kabelschuh zur elektrischen Anbindung einer Masseleitung einer Fahrzeugbatterie an eine Fahrzeugkarosserie eines Kraftfahrzeuges zugleich eine abstehende Kontaktkontur zur elektrischen Anbindung einer Fremdstarteinrichtung oder eines Ladegeräts an die Fahrzeugkarosserie und damit an die Masse des Kraftfahrzeuges vorzusehen. Durch die Integration des Massefremdstartstützpunktes in den Kabelschuh entfällt dessen separate Herstellung und Montage, wodurch deutliche Kostenvorteile, insbesondere auch im Hinblick auf einen Lager- und Logistikaufwand, erzielt werden können. Durch die Integration des Massefremdstartstützpunktes in den Kabelschuh wird der Massefremdstartstützpunkt in einem einzigen Montageschritt, nämlich bei der Montage des Kabelschuhs an der Fahrzeugkarosserie, montiert, so dass bei dem erfindungsgemäßen Kabelschuh nur dieser einmal montiert werden muss und nicht wie bisher sowohl der Kabelschuh zur elektrischen Anbindung der Masseleitung an die Fahrzeugkarosserie und zudem noch ein separater Massefremdstartstützpunkt an einem anderen Ort der Fahrzeugkarosserie. Neben den reinen Kosten und Montagevorteilen bietet die erfindungsgemäße Lösung durch Reduzierung der Teileanzahl auch einen Gewichtsvorteil, der insbesondere auf lange Sicht gesehen Vorteile bei einem Energieverbrauch des Kraftfahrzeuges bietet.The present invention is based on the general idea of providing at a cable lug for the electrical connection of a ground line of a vehicle battery to a vehicle body of a motor vehicle at the same time a protruding contact contour for the electrical connection of a third-party starter or a charger to the vehicle body and thus to the mass of the motor vehicle. The integration of the mass launching support point in the cable lug eliminates its separate production and assembly, whereby significant cost advantages, especially with regard to storage and logistics costs, can be achieved. Due to the integration of the ground foreign launch base in the cable lug of the mass alien launch base is mounted in a single assembly step, namely during assembly of the cable lug to the vehicle body, so that in the cable lug according to the invention only this must be mounted once and not as before both the cable lug for electrical connection the ground line to the vehicle body and also a separate mass foreign launch base at another location of the vehicle body. In addition to the pure costs and installation advantages, the solution according to the invention also offers a weight advantage by reducing the number of parts, which offers advantages in terms of energy consumption of the motor vehicle, in particular in the long term.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung ist der Kabelschuh über eine Schraubverbindung, eine Crimpverbindung oder eine Schweißverbindung mit der Masseleitung verbunden. Bereits diese Aufzählung lässt erahnen, dass die elektrische Verbindung zur Masseleitung auf vielfache und insbesondere auch individuelle Art bedarfsgerecht ausgewählt werden kann.In an advantageous development of the solution according to the invention, the cable lug is connected to the ground line via a screw connection, a crimp connection or a welded connection. Already this list suggests that the electrical connection to the ground line can be selected in many ways and in particular individual needs.
Zweckmäßig ist die Kontaktkontur als Kontaktfläche oder als Massebolzen ausgebildet. Die Kontaktkontur zur elektrischen Anbindung beispielsweise eines Massekabels eines Ladegerätes muss demzufolge lediglich derart ausgebildet sein, dass eine leichte und zugleich zuverlässige Kontaktierung bzw. Befestigung einer Klemmzange, die am Massekabel angeordnet ist, möglich ist. Die Ausgestaltung der Kontaktkontur kann dabei individuell gewählt werden, so dass diese beispielsweise als reine, leicht abstehende, insbesondere abgewinkelte, Kontaktfläche oder aber bolzenähnlich, das heißt in der Art eines Massebolzens, ausgebildet ist.The contact contour is expediently designed as a contact surface or as a ground bolt. The contact contour for the electrical connection, for example, a ground cable of a charger must therefore be designed only so that a light and reliable at the same time contacting or fixing a clamping pliers, which is arranged on the ground cable, is possible. The configuration of the contact contour can be chosen individually, so that it is formed, for example, as a pure, slightly protruding, in particular angled, contact surface or bolt-like, that is in the manner of a ground bolt.
Bei einer weiteren vorteilhaften Ausbildungsform der erfindungsgemäßen Lösung weist der Kabelschuh zwischen der Kontaktkontur und der Verbindung mit der Masseleitung eine Öse zur Anbindung an die Fahrzeugkarosserie auf. Im günstigsten Fall, das heißt beim Vorsehen einer reinen Öse in der Art einer Durchgangsöffnung, kann somit der Kabelschuh als metallisches Stanz-/Formteil ausgebildet sein, welches rationell und dadurch kostengünstig herstellbar ist. Dabei wird zunächst aus einem ebenen metallischen Werkstoff mittels eines entsprechenden Stanzwerkzeuges der Kabelschuh ausgestanzt und anschließend in die später erforderliche Form umgeformt. Diese spätere Form kann sich insbesondere individuell an entsprechende fahrzeugspezifische Anforderungen orientieren, wobei die spätere Form durch ein einfaches Ändern des formgebenden Werkzeugs leicht anpassbar ist. In a further advantageous embodiment of the solution according to the invention, the cable lug has an eyelet for connection to the vehicle body between the contact contour and the connection to the ground line. In the best case, that is, when providing a pure eyelet in the manner of a through hole, thus the lug can be formed as a metallic stamped / molded part, which is rational and thus inexpensive to produce. In this case, the lug is first punched out of a flat metallic material by means of a corresponding punching tool and then formed into the shape required later. This later form can in particular be oriented individually to corresponding vehicle-specific requirements, wherein the later shape is easily adaptable by simply changing the shaping tool.
Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Figurenbeschreibung anhand der Zeichnung.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawing and from the associated description of the figures with reference to the drawing.
Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination but also in other combinations or in isolation without departing from the scope of the present invention.
Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird in der nachfolgenden Beschreibung näher erläutert.A preferred embodiment of the invention is illustrated in the drawing and will be explained in more detail in the following description.
