Abstract

The method enables an electrical connection to be made between a terminal part (1) and an insulated cable made up of several stranded conductive wires (2). The connection uses a holder element (6) which holds the partially uninsulated cable end inside a stepped bore (4) in the terminal part (1). An expansion mandrel (6) is pressed through the opposing bore opening into the wire body (2) of the cable end by means of an ultrasonic sonotrode (5). This mechanically fixes the end of the cable inside the partially roughened stepped bore (4). At the same time, the ultrasonic effect causes contact welding of the wire body (2) within itself and to the inner wall of the bore.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer elektrischen Verbindung zwischen einem festinstallierten oder bewegbaren Anschlußteil und einem aus einer Vielzahl miteinander verseilter Leiterdrähte bestehenden isolierten Kabel.The invention relates to a method for producing an electrical connection between a permanently installed or movable connecting part and an insulated cable consisting of a plurality of conductor wires stranded together.

Zu diesem Zweck ist aus der DE 38 13 497 C2 eine Verbindungsherstellung bekannt, bei welcher das teilweise abisolierte Kabelende unter Verwendung eines besonderen Halterungselements innerhalb einer durchgehenden Bohrung des Anschlußteils festgelegt wird. Dabei zieht eine Spezialschraube das entsprechend abisolierte Kabelende in die hierzu abgestufte Bohrung hinein und preßt zugleich den Drahtkörper mitsamt seiner Isolierung kontaktschlüssig wie abdichtend gegen die Bohrungswandungen.For this purpose, a connection is known from DE 38 13 497 C2, in which the partially stripped cable end is fixed using a special mounting element within a through bore of the connecting part. A special screw pulls the appropriately stripped cable end into the graduated hole and at the same time presses the wire body and its insulation against the walls of the hole in a contact-locking and sealing manner.

Der Erfindung liegt die Aufgabe zugrunde, das bekannte Verfahren technologisch zu vereinfachen und zu verbessern, um in Anbetracht der relativ geringen Berührungsflächen auf beiden Seiten der zu verbindenden Teile mechanisch zu einem möglichst wirksamen Kraftschluß und elektrisch zu einem möglichst kleinen Übergangswiderstand zu gelangen.The invention has for its object to technologically simplify and improve the known method, in view of the relatively small contact surfaces on both sides of the parts to be connected mechanically to achieve the most effective frictional connection and electrically to the smallest possible contact resistance.

Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den in Anspruch 1 bezeichneten Fertigungsschritten gelöst. - Auf diese Weise bewirkt der verbleibend in die Verbindungsstelle eingetriebene Spreizdorn im Einhergehen mit dem Ultraschall-Schweißvorgang einen mechanisch wie elektrisch zuverlässigen Kabelanschluß.This object is achieved according to the invention by a method with the manufacturing steps described in claim 1. In this way, the expanding mandrel which is driven into the connection point, together with the ultrasonic welding process, brings about a mechanically and electrically reliable cable connection.

Dabei kann der von außen durch die Ultraschallsonotrode in die Stufenbohrung des Anschlußteils eingeführte und weiter in das Kabelende eingepreßte Spreizdorn bei Bedarf länger ausgeführt werden und dementsprechend deutlich über die gegenüberliegende Bohrungsöffnung hinausreichend in den Drahtkörper eindringen, um beispielsweise eine nach Beendigung des Ultraschall-Schweißvorgangs maschinell vorgenommene Umbiegung des Anschlußkabels zu einem U-bügelförmigen Verbindungselement verbleibend in sich zu stabilisieren.The expanding mandrel that is inserted from the outside through the ultrasonic sonotrode into the stepped bore of the connecting part and pressed further into the cable end can be made longer if necessary and accordingly clearly above the opposite one Penetrating hole opening sufficiently into the wire body, for example, to stabilize a bending of the connecting cable into a U-shaped connecting element which is carried out mechanically after the ultrasound welding process has ended.

Gemäß einer Weiterbildung des Verfahrens nach Anspruch 2 kann die Stufenbohrung sowohl im weiteren Bereich der sie tangierenden Kabelisolation als auch davor im eigentlichen Kontaktbereich gegenüber dem verseilten Drahtkörper des Kabels zuvor mit einer geeigneten Aufrauhung ihrer Innenwandung durch Rändeln, Kordieren od.dgl. versehen werden, um die gegenseitige Haftung zu vergrößern.According to a further development of the method according to claim 2, the stepped bore can be provided with a suitable roughening of its inner wall by knurling, cording or the like both in the wider area of the cable insulation tangent to it and before that in the actual contact area with respect to the stranded wire body of the cable. provided to increase mutual liability.

Nach dem Merkmal des Anspruchs 3 besteht die Möglichkeit, eine verfahrensgemäß zustandegekommene Verbindung sowohl zusätzlich an der Eintrittsstelle des Kabels in das Anschlußteil als auch auf Seiten der gegenübergelegenen Bohrungsöffnung für den Eingriff der Ultraschallsonotrode durch einen abschließend über das gesamte Anschlußteil geschobenen und sich demselben alsdann unter Wärmeeinwirkung satt anschmiegenden Schrumpfschlauchfolienabschnitt aus thermoplastischem Material gegen den Zutritt von Feuchtigkeit und Verunreinigungen zu schützen.According to the feature of claim 3, there is the possibility of a connection that has been established in accordance with the method both additionally at the entry point of the cable into the connection part and on the opposite bore opening for the engagement of the ultrasound sonotrode by a slide finally pushed over the entire connection part and then exposed to the same under heat Protect snugly fitting shrink tube section made of thermoplastic material against the ingress of moisture and contaminants.

Ebenso läßt sich die Kabelverbindung vorzüglich unter Nutzung der Funktion des Anschlußteils an dessen freibleibender Bohrungsöffnung abdichten, indem gemäß einer Weiterbildung der Erfindung nach dem Merkmal des Anspruchs 4 die korrespondierenden Elemente einer Steckverbindung unter Verwendung einer den mit einem Dichtungsring versehenen Anschlußteil hintergreifenden Überwurfmutter aus Kunststoff miteinander verschraubt werden.Likewise, the cable connection can be sealed using the function of the connection part at its free bore opening, by screwing together the corresponding elements of a plug connection using a plastic union nut engaging behind the connection part provided with a sealing ring, according to a development of the invention according to the feature of claim 4 become.

Als Ausführungsbeispiel ist in Fig. 1 der anliegenden Zeichnung eine nach dem erfindungsgemäßen Verfahren hergestellte Verbindung zwischen einem nicht näher definierten Anschlußteil 1 und dem aus Seiterdrähten 2 litzenartig verseilten Kabel(-ende) mit einer Kunststoffummantelung 3 im Schnitt dargestellt. Dabei ist dieses
Anschlußteil 1, beispielsweise als Polanschlußklemme für einen Akkumulator, mit einer durchgehend von beiden Seiten her zugänglichen Stufenbohrung 4 versehen, deren Durchmesser an der Einstecköffnung dem des kunststoffummantelten Kabels (3) entspricht und sich im Inneren der Bohrung 4 abgesetzt auf den Durchmesser des abisolierten Drahtkörpers 2 verringert. In diese kleinere Öffnung der Bohrung 4 führt dann die Sonotrode 5 einer gebräuchlichen Ultraschall-Schweißvorrichtung den zylindrischen Spreizdorn 6 hinein und preßt ihn aufweitend zunächst zentral in den Drahtkörper 2 des Kabels und dann weiter axial samt der Kunststoffummantelung 3 gegen die Innenwandung der Stufenbohrung 4. Dabei kann sich eine gewisse Aufrauhung der Bohrungsinnenwandung als nützlich erweisen. - Simultan dazu oder zeitlich mit geringer Verzögerung erfolgt dann die Preßschweißung durch longitudinale Ultraschallschwingungen. Durch diese Schubwellen, die sich von der Sonotrode 5 in den von ihr zeitweilig gehalterten Spreizdorn 6 fortpflanzen, entsteht an den Kontaktflächen Reibung, wodurch die Struktur an den Oberflächen zerstört wird und sich die Metalle von Anschlußteil 1 und Drahtkörper 2 bereichsweise fest und kontaktschlüssig miteinander verbinden. Dabei bewirkt der über die Kabeleintrittsstelle hinaus in den Drahtkörper 2 eingepreßte Spreizdorn 6 zur gleichen Zeit einen vorteilhaften Knickschutz für das angeschlossene Kabel. Um die bereits verfahrensgemäß zustandegekommene Abdichtung an der Kabeleinführungsöffnung zu sichern und insbesondere die ihr gegenüberliegende Einführungsöffnung für den Spreizdorn 6 nachträglich abzudichten, wird das verkabelte Anschlußteil 1 ab abschließend mit einem thermoplastischen Schrumpfschlauchfolienabschnitt (7) überzogen und thermisch versiegelt.As an exemplary embodiment, FIG. 1 of the accompanying drawing shows a connection, produced by the method according to the invention, between an unspecified connection part 1 and the cable (end) stranded from stranded wires 2 with a plastic sheath 3 in section. Here is this
Connection part 1, for example as a pole connection terminal for an accumulator, is provided with a stepped bore 4 which is continuously accessible from both sides, the diameter of which at the insertion opening corresponds to that of the plastic-coated cable (3) and is offset in the interior of the bore 4 to the diameter of the stripped wire body 2 decreased. The sonotrode 5 of a conventional ultrasonic welding device then leads the cylindrical expanding mandrel 6 into this smaller opening in the bore 4 and then expands it centrally into the wire body 2 of the cable and then further axially together with the plastic sheath 3 against the inner wall of the stepped bore 4 a certain roughening of the inner wall of the bore can prove useful. - Simultaneously or with a slight delay, the pressure welding is then carried out by longitudinal ultrasonic vibrations. These shear waves, which propagate from the sonotrode 5 into the expanding mandrel 6 which it temporarily holds, create friction at the contact surfaces, as a result of which the structure on the surfaces is destroyed and the metals of the connecting part 1 and the wire body 2 are partially firmly and contact-wise connected to one another . The expanding mandrel 6, which is pressed into the wire body 2 beyond the cable entry point, at the same time brings about an advantageous kink protection for the connected cable. In order to secure the seal on the cable entry opening, which has already been established in accordance with the method, and in particular to subsequently seal the opposite insertion opening for the expanding mandrel 6, the wired connecting part 1 is finally covered with a thermoplastic shrink tube section (7) and thermally sealed.

Eine andere Möglichkeit, die Einführungsöffnung für einen außerdem länger ausgeführten Spreizdorn 6 abzudichten, ist in Fig. 2 der Zeichnung - teilweise im Schnitt - anhand eines Drahtbügels zur Verbindung zweier Batteriepole dargestellt. Hierbei sind die Anschlußteile 1 am jeweiligen Kabelende als konische Hülsen (taper pins) ausgebildet, um form- und kontaktschlüssig in die korrespondierend ausgeführten Sacklochbohrungen 8 der Batteriepole 9 eingesteckt werden zu können. Im unbenutzten Zustand lassen sich diese Sacklochbohrungen 8 außerdem noch gegen das Eindringen von Verunreinigungen und Feuchtigkeit schützen, indem sie mit einem Formstopfen aus Schaumstoff bestückt werden, welcher im Zuge der Verbindungsherstellung vor der eingeführten Steckhülse 1 ohne weiteres in einen am Boden der Bohrung vorgesehenen Leerraum ausweichen kann. Wie aus der links im Bild geschnitten dargestellten Kabelverbindung ersichtlich, ist in das partiell abisoliert in die Stufenbohrung 4 der Steckhülse 1 eingeschobene Kabelende durch die gegenübergelegene Bohrungsöffnung mittels der Ultraschallsonotrode ein verlängerter Spreizdorn 6 eingepreßt und nach Beendigung des Ultraschall-Schweißvorgangs mitsamt dem Anschlußkabel rechtwinklig umgebogen worden, um auf diese Weise zu einem in Grenzen elastischen Verbindungsglied zwischen zwei benachbarten Batteriepolen 9 zu gelangen. Dabei wird die ungeschützte Bohrungsöffnung vorn an der Steckhülse 1 im Zuge der Benutzung gegen den Zutritt von Verunreinigungen und Feuchtigkeit gesichert, wozu eine die Steckhülse 1 kabeleinführungsseitig hintergreifende Überwurfmutter 10 aus Kunststoff mit einem Gewindeansatz rings um die Sacklochbohrung 8 des Batteriepols 9 verschraubt wird und dabei einen von der Steckhülse 1 getragenen Dichtungsring 11 gegen die Öffnungsrandung der Sacklochbohrung 8 preßt. Zudem sichert diese Maßnahme generell die hergestellte Steckverbindung. Für deren Lösen kann die Steckhülse 1 kabeleinführungsseitig zur Halterung der Überwurfmutter 10 mit einem (sechskantig) profilierten Flansch versehen werden, welcher den lockernden Ansatz eines Werkzeugs ermöglicht.Another possibility of sealing the insertion opening for an expanding mandrel 6, which is also longer, is shown in FIG. 2 of the drawing — partly in section — using a wire bracket for connecting two battery poles. Here, the connection parts 1 are formed at the respective cable end as conical sleeves (taper pins) in order to be form-fitting and contact-locking to be able to be inserted into the correspondingly designed blind holes 8 of the battery poles 9. In the unused state, these blind holes 8 can also be protected against the ingress of contaminants and moisture by fitting them with a molded plug made of foam, which in the course of establishing the connection can easily escape before the inserted socket 1 into an empty space provided at the bottom of the hole can. As can be seen from the cable connection shown on the left in the figure, an extended expanding mandrel 6 is pressed into the partially stripped cable end into the stepped bore 4 of the socket 1 through the opposite bore opening by means of the ultrasonic sonotrode and bent at right angles together with the connecting cable after the ultrasonic welding process has ended in order in this way to arrive at a connection member between two adjacent battery poles 9 which is elastic within limits. The unprotected bore opening on the front of the plug-in sleeve 1 is secured in the course of use against the ingress of contaminants and moisture, for which purpose a union nut 10, which engages behind the plug-in sleeve 1 on the cable entry side, is screwed with a threaded attachment around the blind hole 8 of the battery pole 9 and thereby one from the receptacle 1 worn sealing ring 11 presses against the opening edge of the blind hole 8. In addition, this measure generally secures the plug connection that is produced. To release them, the plug-in sleeve 1 can be provided on the cable entry side for holding the union nut 10 with a (hexagonal) profiled flange, which enables the loosening of a tool.
