Abstract
Description
Die Erfindung betrifft eine Verbindungsanordnung für eine elektrische Leiterverbindung mit einem Kabelschuh, insbesondere zur Verwendung in einem Fahrzeug.The invention relates to a connection arrangement for one electrical conductor connection with a cable lug, in particular for use in a vehicle.
In einem Fahrzeug werden wasserdichte Kabelschuhe benötigt, um einen Feuchtigkeitseintritt in das Fahrzeugbordnetz zu verhindern, der insbesondere durch Temperaturschwankungen und Kapillarwirkung bis hin zum Endverbraucher bedingt sein kann. Feuchtigkeit und Wasser führen wiederum zu Korrosion und Kriechströmen, die einen Ausfall von Funktionen elektrischer Komponenten und damit eine Störung im Fahrbetrieb bis hin zum Liegenbleiben des Fahrzeugs verursachen können.In a vehicle become watertight Cable lugs required, to prevent moisture from entering the vehicle electrical system, which in particular due to temperature fluctuations and capillary action down to the end consumer. Moisture and water to lead turn to corrosion and leakage currents, which cause a failure of functions electrical components and thus a malfunction while driving can cause the vehicle to stop.
Daher sind wasserdichte Kabelschuhe
entwickelt worden, die einen Feuchtigkeitseintritt in das Bordnetz
verhindern. Aus der
Aus der Beschreibung des Standes der Technik in der genannten Schrift geht aber auch hervor, daß es schon bekannt ist, die Verbindung eines Leiters mit einem Kabelschuh so vorzunehmen, daß der Leiter mit einem isolierten Teilbereich in den hohlzylindrischen Teil des Kabelschuhs eingeführt und in diesem mitverpreßt wird.From the description of the stand The technology in the cited document also shows that it does is known, the connection of a conductor with a cable lug so make the Conductor with an isolated section in the hollow cylindrical Part of the cable lug inserted and pressed in this becomes.

Standes der Technik zeigt die
Es ist daher Aufgabe der Erfindung, eine Verbindungsanordnung für eine elektrische Leiterverbindung mit einem Kabelschuh nach dem Oberbegriff des Anspruchs 1 so zu gestalten, daß die Zuverlässigkeit der Verbindung bei Sicherstellung eines Feuchtigkeitsschutzes für die angeschlossene Leitung erhöht ist.It is therefore an object of the invention a connection arrangement for an electrical conductor connection with a cable lug after Preamble of claim 1 to be designed so that the reliability the connection while ensuring moisture protection for the connected Line increased is.
Diese Aufgabe wird bei einer Verbindungsanordnung nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale erhöht. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.This task is done with a connection arrangement according to the preamble of claim 1 by its characterizing Characteristics increased. advantageous Refinements are listed in the subclaims.
Die Erfindung besteht danach darin, daß bei einer Verbindungsanordnung für eine elektrische Leiterverbindung mit einem Kabelschuh, gebildet aus einer Anschlußlasche zur Verbindung mit einem elektrischen Leiter oder einem Bauteil und einem an die Anschlußlasche angeformten Hohlzylinderteil zur Aufnahme des Endabschnittes eines elektrischen Leiters mit einem abisolierten Endbereich mit einem ersten (Hohlzylinder-) Teilabschnitt zum Crimpen an den abisolierten Leiter und einem zweiten Teilabschnitt zum Crimpen an die Leiterisolation, zwischen dem Leiter und der Leiterisolation ein Zwischenring angeordnet ist. Der äußere Durchmesser der Leiterisolation im Bereich dieses Zwischenringes entspricht im wesentlichen dem inneren Durchmesser des zweiten Teilabschnitts, ist jedoch nicht größer als dieser. Durch die Anordnung des Zwischenringes wird die Leiterisolation im Bereich des Zwischenringes elastisch aufgeweitet und an diesen gespannt, so daß die Crimpverbindung mit dem Kabelschuh besonders fest und feuchtigkeitsdicht ist.The invention then consists in that at a Connection arrangement for an electrical conductor connection with a cable lug from a connection tab for connection to an electrical conductor or a component and one to the connector tab molded hollow cylinder part for receiving the end portion of a electrical conductor with a stripped end portion with a first (Hollow cylinder) section for crimping on the stripped conductor and a second section for crimping onto the conductor insulation, an intermediate ring is arranged between the conductor and the conductor insulation is. The outer diameter the conductor insulation in the area of this intermediate ring corresponds to essentially the inner diameter of the second section, however, is not greater than this. The conductor insulation is provided by the arrangement of the intermediate ring in the area of the intermediate ring elastically expanded and on this clamped so that the crimp connection is particularly firm and moisture-proof with the cable lug.
Bevorzugt ist der Zwischenring zur weiteren Erhöhung der Festigkeit und Zuverlässigkeit der Verbindungsanordnung im Abstand vom freien Ende bzw. der Stirnseite des Hohlzylinderteils angeordnet, und die Crimpverbindung ist in den zwischenringfreien Endbereich gelegt. Dadurch ist der Hohlzylinderteil im zweiten Teilabschnitt mit der den Leiter umgebenden Isolation als auch mit der einen Teil des Zwischenringes unter Aufweitung und Durchmesservergrößerung gespannt umschließenden Isolation verpreßt, so daß der Hohlzylinderteil die umfangsseitig keulenartig geformte Isolation gleichsam fest einschließt.The intermediate ring is preferred further increase of strength and reliability the connection arrangement at a distance from the free end or the end face of the hollow cylindrical part, and the crimp connection is in the end ring-free area. This is the hollow cylinder part in the second section with the insulation surrounding the conductor as well as with part of the intermediate ring with expansion and increased diameter enclosing Insulation pressed, so that the Hollow cylinder part the insulation shaped like a club on the circumference as it were firmly enclosed.
Zur Unterstützung des Einbringens des Zwischenringes zwischen den Leiter und die Isolation ist es vorteilhaft, wenn der Zwischenring einen trapezförmigen oder linsenförmigen, umfangsseitig verjüngten Querschnitt aufweist. Dadurch ergeben sich Einführschrägen, die ein Eindrücken des Zwischenringes erheblich erleichtern. Die kantenfreien Schrägen ermöglichen auch ein hohlraumfreies Anliegen der Isolation an den Zwischenring und verhindern so eine kantenbedingte Beschädigung der Isolation. Allerdings kann es wegen eines festeren Sitzes derselben auf dem Zwischenring vorteilhaft sein, wenn dessen Oberfläche kantenfrei leicht strukturiert ist. Der Zwischenring kann aus Metall oder Kunststoff bestehen, da dieser keine elektrische Funktion zu erfüllen hat.To support the insertion of the intermediate ring between the conductor and the insulation, it is advantageous if the Intermediate ring a trapezoidal or lenticular, circumferentially tapered Has cross-section. This results in insertion bevels that impress the Lighten the intermediate ring considerably. The edge-free bevels allow also a cavity-free application of the insulation to the intermediate ring and thus prevent edge-related damage to the insulation. Indeed it may be because of a more tight fit of the same on the intermediate ring be advantageous if its surface is slightly structured without edges is. The intermediate ring can be made of metal or plastic, since this has no electrical function to perform.
Alternativ zu der vorbeschriebenen Verbindungsanordnung kann diese auch derartig gestaltet sein, daß ein aus einem elektrisch gut leitenden Werkstoff, insbesondere Cu oder Al, bestehender Zwischenring im zweiten und im ersten Teilabschnitt angeordnet und derart abgesetzt ist, daß dieser im ersten Teilabschnitt einen Außendurchmesser aufweist, der im wesentlichen dem Innendurchmesser des Hohlzylinderteils entspricht und somit den Raum zwischen diesem und dem Leiter ausfüllt, und im zweiten Teilabschnitt einen kleineren Außendurchmesser aufweist, der zusätzlich noch die Anordnung der aufgeweiteten Isolation zwischen diesem und dem Hohlzylinderteil gestattet. Die Crimpverbindung im zweiten Teilabschnitt zwischen dem Hohlzylinderteil und der Isolation entspricht dabei der der vorhergehend beschriebenen, wohingegen die Crimpverbindung im ersten Teilabschnitt zwischen dem Leiter und dem Hohlzylinderteil unter Einbeziehung des Zwischenringes erfolgt. Dabei kann dieser im ersten Teilbereich mit einem Längsschlitz versehen sein, um dessen Verquetschen mit dem Leiter zu erleichtern, und im zweiten Teilbereich wiederum einen trapez- oder linsenförmigen Querschnitt mit den oben beschriebenen Vorteilen aufweisen. Der Vorteil dieser Lösung liegt darin, daß der Hohlzylinderteil einen einheitlichen Innendurchmesser aufweisen kann und damit weniger aufwendig ist.As an alternative to the one described above Connection arrangement, this can also be designed such that a an electrically highly conductive material, in particular Cu or Al, existing intermediate ring arranged in the second and in the first section and is set down so that this in the first section has an outer diameter that corresponds essentially to the inside diameter of the hollow cylinder part and thus fills the space between this and the conductor, and has a smaller outer diameter in the second section, which additionally nor the arrangement of the expanded insulation between this and the Hollow cylinder part allowed. The crimp connection in the second section corresponds between the hollow cylinder part and the insulation that of the previously described, whereas the crimp connection in the first section between the conductor and the hollow cylinder part with the inclusion of the intermediate ring. This can be provided with a longitudinal slot in the first section, around which Squeeze with the ladder to facilitate, and in the second section again a trapezoidal or lenticular cross section with the have advantages described above. The advantage of this solution is in that the Hollow cylinder part have a uniform inner diameter can and is therefore less expensive.
