Description

Kabelbaum und Verfahren zu seiner herstellung Die Erfindung bezieht sich auf einen Kabelbaum mit einer um diesen aufgebrachten streifen- oder bandförmigen Schutzhülle aus thermoplastischem Kunststoff, die nach dem Aufbringen zu einem geschlossenen Körper von in etwa rohrförmiger Gestalt vereinigt wird und ein Verfahren zur Ilerstellung eines solchen Kabelbaumes. Wire harness and method of making it The invention relates to on a wiring harness with a strip or band-like applied around it Protective cover made of thermoplastic material, which after application becomes a closed Body of approximately tubular shape is combined and a method for Ilerstellung such a wiring harness.

Es ist bekannt, einen Kabelsatz für Kraftfahrzeuge mit einem PVC-Band oder einer PVC-Folie zu umwickeln und die überlappenden Teile T durch Kleben oder Kalt- bzw. Warmschweißen zu verbinden (deutsche Patentanmeldung S 1631, Kl. 21c, 7/ol vom 23.8.1951). Dieses Verfahren ist aber derart zeitaufwendia, daß man dazu übergegangen ist, die einzelnen Adern des Kabelbaumes in geschlossene, rohrförmige Hüllen aus Gummi oder Kunststoff einzulegen.It is known a harness for motor vehicles with a PVC tape or a PVC film to wrap and the overlapping parts T by gluing or To join cold or hot welding (German patent application S 1631, class 21c, 7 / ol of August 23, 1951). However, this procedure is so time-consuming that one has to do it has passed, the individual wires of the cable harness in closed, tubular Insert sleeves made of rubber or plastic.

Nachteilig ist hierbei, daß das Einführen der Adern in rohrförmige nullen besonders bei längeren Hüllen schwierig durchzuführen ist. Hinzu kommt, daß die Enden der Adern frei von Anschlüssen oder dergleichen sein müssen, weil diese aufgrund ihrer Ausdehnung meist nicht durch die enge lliille gezogen werden können. Bei Reparaturarbeiten kommt als weiterer Nachteil hinzu, daß eine losgelöste Ader von der anderen Seite leicht in die Umhüllung gezogen werden kann, wobei ein nachträgliches Wiederherausziehen nur noch sehr schwer zu bewerkstelligen ist.The disadvantage here is that the introduction of the wires into tubular zeroing is difficult to carry out, especially with longer envelopes. In addition, that the ends of the wires must be free of connections or the like, because these Due to their size, they usually cannot be pulled through the narrow groove. In the case of repair work, there is a further disadvantage that a loosened wire can easily be pulled into the envelope from the other side, with a subsequent Pulling it out is now very difficult to do.

Man hat deshalb die zu einem Kabelbaum zusnmlilcnzufassenden Adern mit einen.You therefore have the wires to be combined to form a cable harness with one.

selbstklebenden Kunststoffband wendelförmiB umwickelt. Zwar wurden dadurch die ebenerwähnten Nachteile ausgeschaltet, der Zeitaufwand für die Umwickelarbeit konnte aber nicht spürbar reduziert werden.self-adhesive plastic tape wrapped in a spiral shape. True were this eliminates the disadvantages just mentioned, the time required for the wrapping work but could not be reduced noticeably.

Es ist weiterhin bekannt, die einzelnen Adern eines Kabelbaumes zu einem Plachleiter zusammenzulegen und sie auf einer bzw. beiden Seiten mit Bändern aus thermoplastischell Kunststoff mittels eines hochfrequenten hTechu 1 -stromes zu verschweißen (DOS 1 616 990; DOS 1 590 846). Die Verschweißung mittels Hochfrequenz ist aber im wesentlichen nur für Kabel mit nebeneinanderliegenden Adern geeignet. Ein kontinuierliches Verschweißen ist ohne weiteres nicht möglich. Dariiberhinaus ist dieser Verschweißvorgang immer noch sehr aufwendig, so daß eine billige Herstellungsweise nicht möglich ist. Ungiinstig ist auch, daß das Verschweißwerkzeug den herzustellenden Kabelbawn geometrisch angepaßt werden muß und für stark in ihren geometrischen Abmessungen differ-ierende Kabelbäume unterschiedliche Verschweißwerkzeuge bereitgestellt werden müssen.It is also known to connect the individual wires of a cable harness one Lay plan ladder together and place them on one or both Pages with tapes made of thermoplastic plastic by means of a high frequency hTechu 1 -stromes to be welded (DOS 1 616 990; DOS 1 590 846). The welding however, by means of high frequency is essentially only for cables with adjacent Cores suitable. Continuous welding is not readily possible. In addition, this welding process is still very expensive, so that a cheap production is not possible. It is also unfavorable that the welding tool the Kabelbawn to be produced must be geometrically adapted and for strong in their Cable harnesses differing in their geometrical dimensions and different welding tools must be provided.

Der Erfindung liegt die Aufgabe zugrunde, einen Kabelbaum zu entwerfen, der wirtschaftlich herzustellen ist. Weiterhin sollen die Adern des Kabelbaumes vorgeformt und mit allen Anschlüssen versehen werden könnten, ehe die Zusammenfassung durch die Schutzhülle erfolgt. Darüberhinaus ist Aufgabe der Erfindung, mit einem Verschweißwerkzeug Kabelbäume von unterschiedlichen geometrischen Abmessungen herstellen zu können.The invention is based on the object of designing a cable harness, which can be produced economically. Furthermore, the wires of the wiring harness could be preformed and fitted with all connections before the summary takes place through the protective cover. In addition, the object of the invention is with a Welding tool to produce cable harnesses of different geometrical dimensions to be able to.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die parallel zur Kabelbaumachse verIXaufende(n) Verbindungsstelle(n), die durch die aneinanderstoßende(n) Elandzone(n) der Schutzhülle gebildet werden, mittels Ultraschall vereinigt werden.The object is achieved in that the parallel junction (s) running towards the wiring harness axis, which are caused by the Elandzone (s) of the protective cover are formed, are united by means of ultrasound.

Zwar sind Ultraschatlschweißgeräte bekannt. Sie werden aber für ganz andere technische Zwecke eingesetzt, so z. B. zum Befestigen von Anschlußleitungen auf Platten elektrische Schaltungen (DAS 2 oo7 266).Ultrasonic welding devices are known. But you will for the whole used for other technical purposes, e.g. B. for attaching connecting cables on panels electrical circuits (DAS 2 oo7 266).

Demgegeniil)er wird durch die Erfindung ein preiswerter Kabelbaum. geschaffeii, bei dem die aneinanderstoßende(n) Randzone(n) zuverlässig verbunden sind.On the other hand, the invention makes it an inexpensive cable harness. created, in which the abutting edge zone (s) are reliably connected are.

Da es hier nur auf die Naht ankommt, können mit ein und derselben Verschweißmaschine nicht nur die dicksten Stellen des Kabelbaumes sondern auch seine Abzweigungen, die wesentlich dünner sein können, mit einer geschlossenen Schutzhülle versehen werden. - Es ist hierbei gleichgiiltig, ob nur eine Folie um den Kabelbaum gelegt wird~ und die parallel zur iCabelbaumlängsachse verlaufende Verbindungsstelle verschweißt wird oder ob rnan zwei Folien verwendet, die jeweils von unten und oben aufgebracht werden, wobei dünn zwei Verbindungsstellen entstehen.Since it is only the seam that matters here, you can use one and the same Welding machine not only the thickest parts of the cable harness but even its branches, which can be much thinner, with a closed protective cover be provided. - It is irrelevant here whether there is only a film around the cable harness ~ and the connection point running parallel to the longitudinal axis of the cable harness is welded or whether two foils are used, one from the bottom and one from the top are applied, whereby two thin connection points are created.

Zweckmäßig wird die Vereinigungsstelle in Art einer perforierten Naht verbunden, wobei die Perforation kreuzgewebeförnig ausgebildet sein kann.The union point is expedient in the manner of a perforated seam connected, wherein the perforation can be formed cross-weave.

Hierdurch wird eine hervorragende Verbindung der Kunststoffolie(n), die vorzugsweise aus PVC hergestellt sind, erreicht. Die Naht ist dabei höchstens 5 mm breit.This creates an excellent connection between the plastic film (s), which are preferably made of PVC, achieved. The seam is at most 5 mm wide.

Das Herstellverfahren geschieht nach einem weiteren Merkmal der Erfindung dadurch, daß die als perforiertes Rad ausgebildete untere Sonotrode zusammen mit der oberen Sonotrode unter Druck die Verschweißung vornimmt und gleichzeitig für den Vorschub sorgt, wodurch die Verschweißung kontinuierlich erfolgt.The manufacturing process takes place according to a further feature of the invention in that the lower sonotrode designed as a perforated wheel together with the upper sonotrode carries out the welding under pressure and at the same time for ensures the feed, whereby the welding takes place continuously.
