Description
Die Erfindung betrifft eine elektrische Leitung, die einen elektrischen Schirm aufweist, der mit einer zusätzlichen Leitung kontaktiert ist und eine Schirmausleitung bildet.The invention relates to an electrical line having an electrical screen, which is contacted with an additional line and forms a Schirmausleitung.
Elektrische Leitungen der eingangs genannten Art werden beispielsweise im Automobilbereich dazu verwendet, um elektrische Aggregate und Komponenten miteinander zu verbinden. Um Material und Gewicht zu sparen, ist dabei eine generelle Tendenz zu immer höheren Betriebsspannungen zu beobachten, die geringere Leitungsquerschnitte gestatten. Das gilt insbesondere für Fahrzeuge mit einem rein elektrischen Antrieb oder mit einem Hybridantrieb. In solchen Fahrzeugen werden Geräte und Verbraucher in zunehmendem Maße daher aus Stromquellen mit erhöhter Spannung versorgt. Die dabei eingesetzten Stromquellen können für Spannungen von bis zu 1000 V ausgelegt sein. Verbraucher sind beispielsweise Klimakompressoren und insbesondere bei Elektrofahrzeugen ein Antriebsmotor sowie vorhandene Heizgeräte. Ein aktives Gerät ist beispielsweise das Ladegerät zum Aufladen einer Batterie. Für die Verbindung von Verbrauchern und Geräten mit einer entsprechenden Batterie bzw. mit einer an dieselbe angeschlossenen Steuerelektronik werden mit einem elektrisch wirksamen Schirm versehene elektrische Leitungen eingesetzt. Vielfach ist es bei solchen Leitungen erforderlich, den Schirm der elektrischen Leitungen mit Masse zu verbinden. Bei der Verwendung der Leitungen in Fahrzeugen sind sie rauen Einsatzbedingungen ausgesetzt, insbesondere mechanischen Erschütterungen, Schmutz, und Spritzwasser. Trotzdem wird verlangt, dass die betreffenden elektrischen Leitungen und deren Anschlüsse über eine lange Einsatzdauer zuverlässig funktionieren.Electrical lines of the type mentioned are used for example in the automotive sector to connect electrical units and components together. In order to save material and weight, a general tendency is to observe ever higher operating voltages, which allow smaller cable cross-sections. This applies in particular to vehicles with a purely electric drive or with a hybrid drive. In such vehicles, devices and consumers are therefore increasingly supplied from power sources with increased voltage. The power sources used can be designed for voltages of up to 1000 V. Consumers are, for example, air conditioning compressors and especially in electric vehicles, a drive motor and existing heaters. An active device is, for example, the charger for charging a battery. For the connection of consumers and devices with a corresponding battery or connected to the same control electronics are provided with an electrically effective screen provided electrical lines. It is often necessary in such lines to connect the shield of the electrical lines to ground. When using the cables in vehicles, they are exposed to harsh operating conditions, in particular mechanical vibrations, dirt, and splash water. Nevertheless, it is required that the respective electrical lines and their connections function reliably over a long service life.
Aus der
Hiervon ausgehend hat die vorliegende Erfindung die Aufgabe, elektrische Leitung mit einer Schirmausleitung zu schaffen, die einfacher herzustellen ist.On this basis, the present invention has the object to provide electrical cable with a screen outlet, which is easier to manufacture.
Zur Lösung dieser Aufgabe schlägt die Erfindung eine elektrische Leitung mit mindestens einem isolierten Leiter vor, der von einem elektrischen Schirm umgeben ist, der an einer Kontaktstelle mit einem zusätzlichen Leiter kontaktiert ist, der eine Schirmausleitung bildet. Um die Kontaktstelle ist ein dicht abschließendes Gehäuse auf der elektrischen Leitung montiert.To achieve this object, the invention proposes an electrical line with at least one insulated conductor, which is surrounded by an electrical screen, which is contacted at a contact point with an additional conductor forming a Schirmausleitung. Around the contact point, a tightly sealed housing is mounted on the electrical line.
Bei einem Ausführungsbeispiel kann die elektrische Leitung mehrere isolierte Leiter aufweisen.In one embodiment, the electrical line may include a plurality of insulated conductors.
Die vorgeschlagene Lösung ist so konzipiert, dass einadrige und mehradrige Leitungen zum Beispiel HV-Silikon-Mantelleitungen in Temperaturbereichen bis 180 °C eingesetzt werden können. Der Kontaktbereich zwischen dem elektrischen Schirm der Leitung und der Schirmausleitung ist durch das Gehäuse zuverlässig vor Umwelteinflüssen und insbesondere vor Korrosion geschützt. Das montierte Gehäuse ist auch bei Leitungen einsetzbar, deren Außenmantelmaterial, wie zum Beispiel Silikon, eine wasserdichte Umspritzungslösung, wie sie aus dem Stand der Technik bekannt ist, nicht realisierbar ist.The proposed solution is designed so that single-core and multi-core cables, for example HV silicone sheathed cables in temperature ranges up to 180 ° C can be used. The contact area between the electrical screen of the line and the Schirmausleitung is reliably protected by the housing from environmental influences and especially from corrosion. The assembled housing can also be used in lines whose outer shell material, such as silicone, a waterproof Umspritzungslösung, as is known from the prior art, is not feasible.
Vorteilhafterweise ist in das Gehäuse wenigstens eine Dichtung eingesetzt, die das Gehäuse nach außen abdichtet. Die Dichtung kann zusätzlich noch auf ihrem Außenumfang profiliert sein, insbesondere umlaufende Wülste aufweisen, um die Dichtwirkung noch weiter zu verbessern.Advantageously, at least one seal is inserted into the housing, which seals the housing to the outside. The seal can additionally be profiled on its outer circumference, in particular circumferential beads have to improve the sealing effect even further.
Zweckmäßigerweise kann die Dichtung eine Durchgangsöffnung oder mehrere Durchgangsöffnungen aufweisen.Conveniently, the seal may have a through opening or a plurality of through openings.
Mit Vorteil ist jede Dichtung mittels einer auf dem Gehäuse befestigten Haltekappe in dem Gehäuse gehalten. Die Haltekappe hat darüber hinaus den Vorzug, dass die Dichtung vor mechanischen Einflüssen geschützt wird, die zu einer Beeinträchtigung der Dichtwirkung führen könnten. An dem Gehäuse und der Haltekappe können Rastmittel vorgesehen seien, die eine einfache Montage und gleichzeitig sicheren Sitz der Haltekappe gewährleisten.Advantageously, each seal is held in the housing by means of a retaining cap fixed on the housing. The retaining cap also has the advantage that the seal is protected from mechanical influences, which could lead to a deterioration of the sealing effect. On the housing and the retaining cap locking means may be provided which ensure easy installation and at the same time secure fit of the retaining cap.
In einer vorteilhaften Weiterbildung ist außerdem ein Halteelement vorgesehen, das die Kontaktstelle in dem Gehäuse fixiert. Auf diese Weise wird verhindert, dass sich die Kontaktstelle in dem Gehäuse hin und her bewegt, was im schlimmsten Fall zu einer Beschädigung der Kontaktstelle oder sogar zum Bruch einer Leitung führen könnte.In an advantageous development, a holding element is also provided, which fixes the contact point in the housing. In this way, the contact point in the housing is prevented from being moved back and forth, which in the worst case could damage the contact point or even break a line.
In einer zweckmäßigen Weiterbildung stellt ein Kontaktelement einen elektrischen Kontakt zwischen dem elektrischen Schirm und dem weiteren Leiter her. Das Kontaktelement ermöglicht eine schnelle und einfache Herstellung des Kontaktes zwischen der zusätzlichen Leitung und dem elektrischen Schirm. Das Kontaktelement kann insbesondere ein Kabelschuh sein.In an expedient development, a contact element establishes electrical contact between the electrical screen and the further conductor. The contact element allows a quick and easy production of the contact between the additional line and the electric screen. The contact element may in particular be a cable lug.
Mit Vorteil ist eine Stützhülse vorgesehen, die unter dem elektrischen Schirm angeordnet ist. Die Stützhülse schützt den darunterliegenden inneren Mantel Leitung sowie die in dem inneren Mantel eingebetteten Adern vor einer mechanischen Beschädigung durch einen nachfolgenden Crimp-Prozess.Advantageously, a support sleeve is provided, which is arranged under the electric umbrella. The support sleeve protects the underlying inner jacket line and the cores embedded in the inner jacket from mechanical damage by a subsequent crimping process.
In einer vorteilhaften Weiterbildung umschließt eine Crimphülse das Kontaktelement fest, wodurch der elektrische Schirm zwischen der Stützhülse und dem ringförmigen Kabelschuh festgeklemmt ist. Der Kontakt zu dem elektrischen Schirm wird somit durch einen einfachen standardmäßigen Crimp-Prozess erreicht.In an advantageous development, a crimping sleeve tightly surrounds the contact element, whereby the electric shield between the support sleeve and the annular cable lug is clamped. The contact to the electrical Screen is thus achieved by a simple standard crimping process.
In einer vorteilhaften Weiterbildung der Erfindung trägt die Haltekappe, durch die eine oder mehrere isolierte Leitungen sowie der zusätzliche Leiter hindurchtreten, Kennzeichnungen, welche die einzelnen Leiter sichtbar identifizieren. Zum Beispiel bei der Montage der Leitungen in einem Automobil kann die einfache Identifizierung der Adern der Leitung Vorteile in der Fertigung bringen.In an advantageous development of the invention, the retaining cap, through which one or more insulated lines and the additional conductor pass, bears markings which visibly identify the individual conductors. For example, in the assembly of the wires in an automobile, the simple identification of the wires of the wire can bring advantages in the production.
