Description

Die Erfindung betrifft ein Kontaktierverfahren für einen Draht, insbesondere einen Aluminiumdraht, der mit einem Anschlusskörper, insbesondere einem Stecker eines Spulenkörpers, verbunden wird. Ferner betrifft die Erfindung eine Verbindungsanordnung mit dem Draht und dem Anschlusskörper sowie einen elektrischen Pumpenmotor, der die Verbindungsanordnung aufweist.The invention relates to a contacting method for a wire, in particular an aluminum wire, which is connected to a connecting body, in particular a plug of a bobbin. Furthermore, the invention relates to a connection arrangement with the wire and the connection body and an electric pump motor having the connection arrangement.

Aus dem Stand der Technik sind unterschiedliche Kontaktierungsmethoden bekannt, um einen Draht, beispielsweise einen als Wicklung für einen Elektromotor genutzten Aluminiumdraht, mit dem Anschlusskörper zu verbinden und die zwischen dem Draht und dem Anschlusskörper gebildete Verbindungsstelle zu schützen. Die Verbindung wird im industriellen Umfeld beispielsweise durch Löten oder Schweißen oder Ultraschallbonden hergestellt. Ebenso ist bekannt, eine Schneidklemmtechnik zum Verbinden des Drahts mit dem Anschlusskörper zu verwenden.From the prior art, different contacting methods are known for connecting a wire, for example an aluminum wire used as a winding for an electric motor, to the terminal body and for protecting the joint formed between the wire and the terminal body. The connection is produced in the industrial environment, for example by soldering or welding or ultrasonic bonding. It is also known to use an insulation displacement technique for connecting the wire to the terminal body.

Typischerweise bildet die Verbindungsstelle zwischen dem Draht und dem Anschlusskörper eine Schwachstelle, die es zu schützen gilt. Zum Schutz der Verbindungsstelle ist es insofern bekannt, sie mit thermoplastischen oder duroplastischen Materialien zu umspritzen, sie mit Epoxy oder einem ähnlichen Material zu vergießen oder eine Lackschicht aufzubringen. Ebenso ist aus der CN 204 741 344 U bekannt, ein Fett oder einen anderen Schmierstoff zum Schutz der Verbindungsstelle auf ebendiese aufzubringen. Als Werkstoff kommen hier mit Siliziumoxid verdickte Kohlenwasserstoffe, Polydimethylsiloxan oder ein klassisches Silikon zur Anwendung.Typically, the joint between the wire and the terminal body forms a weak point to be protected. To protect the joint, it is known in the art, they with thermoplastic or thermosetting materials to encapsulate, shed with epoxy or similar material or apply a paint layer. Likewise is from the CN 204 741 344 U It is known to apply a grease or other lubricant to the joint to protect it. The material used here are silica-thickened hydrocarbons, polydimethylsiloxane or a classic silicone.

Auch wenn sich die bekannten Methoden zur Herstellung einer Umhüllung für die Verbindungsstelle in der Praxis grundsätzlich bewährt haben, besteht insbesondere aufgrund der stetig wachsenden Qualitätsstandards und neuer Prüfroutinen (zum Beispiels Salzsprühnebeltests) das Bestreben, die Kontaktierungsmethoden weiter zu verbessern und den Schutz der Verbindungsstelle zu optimieren.Although the known methods for producing a covering for the connection point have basically proven successful in practice, there is a constant effort to further improve the contacting methods and to optimize the protection of the connection point, in particular due to the steadily growing quality standards and new test routines (for example salt spray tests) ,

Aufgabe der Erfindung ist es insofern, ein Kontaktierverfahren, eine Verbindungsanordnung und einen elektrischen Pumpenmotor anzugeben, bei dem die zwischen dem Draht und dem Anschlusskörper gebildete Verbindungsstelle besonders wirtschaftlich hergestellt werden kann und in vorteilhafter Weise gegen schädigende Umgebungseinflüsse geschützt ist.The object of the invention is therefore to provide a contacting method, a connection arrangement and an electric pump motor, in which the connection point formed between the wire and the connection body can be produced particularly economically and is protected in an advantageous manner against damaging environmental influences.

Zur Lösung der Aufgabe weist das erfindungsgemäße Kontaktierverfahren die Merkmale des Patentanspruchs 1 auf.To achieve the object, the contacting method according to the invention has the features of claim 1.

Es wird dabei der Draht mit dem Anschlusskörper stoffschlüssig verbunden. Nach dem Herstellen der Verbindung wird der Schrumpfschlauch mit dem Innenkleber über die Verbindungstelle gelegt.In this case, the wire is firmly bonded to the connection body. After the connection has been made, the heat-shrinkable tube with the inner adhesive is placed over the joint.

Bevorzugt wird der Schrumpfschlauch nach dem Herstellen der Umhüllung erwärmt. Beim Umhüllen der Verbindungsstelle mit dem Schrumpfschlauch beziehungsweise beim Erwärmen des Schrumpfschlauchs kann ein Teil des thermoplastischen Innenklebers durch einen Spalt hindurchtreten, welcher zwischen dem Anschlusskörper und dem Schrumpfschlauch gebildet ist.Preferably, the shrink tube is heated after the production of the envelope. When wrapping the connection point with the shrink tube or when heating the shrink tube, a part of the thermoplastic adhesive inside can pass through a gap which is formed between the connector body and the shrink tube.

Der besondere Vorteil der Erfindung besteht darin, dass die Verbindungsstelle durch den Innenkleber und den Schrumpfschlauch in hervorragender Weise elektrisch isoliert ist. Zugleich sind die Verbindungsstelle und der von der Umhüllung umfasste Teil des Drahts vor Korrosion geschützt. Der Schrumpfschlauch mit dem Innenkleber verhindert den Kontakt mit Sauerstoff beziehungsweise Wasser. Der Schrumpfschlauch ist zudem alterungsbeständig. Durch den Innenkleber sowie den Materialeigenschaften des Schrumpfschlauchs ist Spannungsrissen vorgebeugt beziehungsweise die Neigung zum Verspröden minimiert. Die Verbindungsstelle ist beständig gegen aggressive Medien wie Öl, Säure, Lauge beziehungsweise Salze. Des Weiteren ist eine gute Temperaturbeständigkeit in den normalen Betriebstemperaturbereichen einer Aluminiumwicklung für Spulenkörper gewährleistet. Zudem besteht nicht die Gefahr, dass der Schrumpfschlauch schmilzt, da er bei Temperaturen über den kristallinen Schmelzpunkt nicht mehr fließt, sondern elastisch wird wie ein Elastomer.The particular advantage of the invention is that the connection point is electrically insulated in an outstanding manner by the inner adhesive and the heat-shrinkable tube. At the same time, the connection point and the part of the enclosure enclosed by the enclosure are Wire protected against corrosion. The shrink tube with the inner adhesive prevents contact with oxygen or water. The shrink tubing is also resistant to aging. Due to the internal adhesive as well as the material properties of the heat shrink tube, stress cracks are prevented or the tendency to embrittlement is minimized. The joint is resistant to aggressive media such as oil, acid, alkali or salts. Furthermore, a good temperature resistance in the normal operating temperature ranges of an aluminum coil winding body is ensured. In addition, there is no risk that the shrink tube melts because it no longer flows at temperatures above the crystalline melting point, but becomes elastic like an elastomer.

Die gute Isolation führt zudem dazu, dass der Draht, wenn er als Aluminiumlackdraht ausgeführt ist, keine zusätzliche Isolationsschicht beziehungsweise keinen zusätzlichen Isolationsschutz mehr bedarf. Des Weiteren begünstigt der verschrumpfte Schlauch, mit dem die Verbindungsstelle umhüllt ist, eine gleichmäßige und dauerhafte Krafteinwirkung auf die Verbindungspunkte. Sie stellt eine zusätzliche mechanische Sicherung dar und gewährleistet eine dauerhaft gute Verbindung. Wirtschaftlich sind die Investitionskosten in die Anlagentechnik gering. Der Verbindungsprozess ist großserientauglich und gut beherrschbar. Die Taktzeiten sind gering.The good insulation also means that the wire, when it is designed as aluminum enameled wire, no longer requires an additional insulation layer or no additional insulation protection. In addition, the shrunk tubing that wraps the joint facilitates uniform and sustained force on the junctions. It represents an additional mechanical security and ensures a permanently good connection. Economically, the investment costs in the system engineering are low. The connection process is suitable for mass production and easy to control. The cycle times are low.

Die stoffschlüssige Verbindung zwischen dem Draht und dem Anschlusskörper wird beispielsweise durch Löten oder Schweißen hergestellt. Beispielsweise kann der Draht auf den Anschlusskörper gebondet werden. Beim Herstellen der Bondstelle kommt insbesondere ein Bondautomat zum Einsatz. Dabei wird der Draht von einem Werkzeug des Bondautomaten gegen den Anschlusskörper gedrückt und von dem Werkzeug zu Ultraschallschwingungen angeregt.The cohesive connection between the wire and the connection body is produced for example by soldering or welding. For example, the wire may be bonded to the terminal body. In particular, a bonding machine is used when producing the bonding site. The wire is pressed by a tool of the bonding machine against the connector body and excited by the tool to ultrasonic vibrations.

Nach einer Weiterbildung der Erfindung werden wenigstens zwei Verbindungspunkte ausgebildet. Die wenigstens zwei und bevorzugt alle Verbindungspunkte werden auf einer gleichen Seite des Anschlusskörpers hergestellt.According to a development of the invention, at least two connection points are formed. The at least two and preferably all connection points are produced on a same side of the connection body.

Vorteilhaft kann durch das Bonden von Draht und Anschlusskörper eine stoffschlüssige Verbindung mit einem geringen elektrischen Übergangswiderstand hergestellt werden. Dabei verbessert sich die Zuverlässigkeit der elektrischen Verbindung, wenn zwei oder mehr Verbindungspunkte zwischen dem Draht und dem Anschlusskörper hergestellt werden. Wirtschaftlich vorteilhaft werden die zwei oder mehr Punkte auf einer gemeinsamen Seite des Anschlusskörpers hergestellt, da ein Umpositionieren des Anschlusskörpers und/oder des Drahts beim Herstellen der Verbindung vermieden werden kann.Advantageously, a material connection with a low electrical contact resistance can be produced by the bonding of wire and connection body. Thereby, the reliability of the electrical connection improves when two or more connection points are made between the wire and the terminal body become. Advantageously, the two or more points are produced on a common side of the connection body, since a repositioning of the connection body and / or the wire during the connection can be avoided.

Optional kann vorgesehen sein, dass der Draht vor dem Bonden an dem Anschlusskörper wenigstens grob positioniert wird. Der Anschlusskörper kann zu diesem Zweck Führungsmittel für den Draht vorsehen. Beispielsweise können an dem Anschlusskörper Führungsausnehmungen für den Draht vorgesehen werden.Optionally, it can be provided that the wire is at least roughly positioned on the connecting body before bonding. The connecting body may provide for this purpose guide means for the wire. For example, guide recesses for the wire can be provided on the connection body.

Eine Anwendungsmöglichkeit liegt im Bereich der Kontaktierung von Aluminiumdraht, beispielsweise von Aluminiumlackdraht für eine Aluminiumdrahtwicklung eines Elektromotors, bei der die Kontaktierung des Aluminiumdrahtes durch einen Ultraschall-Drahtbondautomaten erzeugt wird.One application is in the field of contacting aluminum wire, such as aluminum wire for an aluminum wire winding of an electric motor, in which the contacting of the aluminum wire is produced by an ultrasonic wire bonding machine.

Für die Auswahl des Schrumpfschlauches sind die Geometrie des zu isolierenden Bereichs, das heißt die Geometrie des Anschlusskörpers und der Verbindungsstelle zu berücksichtigen sowie die Qualitätsanforderungen, die an das Produkt gerichtet sind, in Betracht zu ziehen. Hierbei sind besonders die Dauereinsatztemperatur des Schrumpfschlauchs sowie die der durch den Draht gebildeten Wicklung zu berücksichtigen. Ein weiterer wichtiger Parameter ist das zu schützende Volumen, welches der Innenkleber abdichten muss. Dies muss bei der Auswahl des Schrumpfschlauches ebenfalls berücksichtigt werden.For the selection of the shrink tubing, the geometry of the area to be insulated, ie the geometry of the connection body and the connection point must be taken into account as well as the quality requirements, which are addressed to the product into consideration. In this case, especially the continuous use temperature of the shrink tube and the winding formed by the wire are taken into account. Another important parameter is the volume to be protected, which the inner adhesive must seal. This must also be taken into account when selecting the shrink tube.

Die Verwendung des Schrumpfschlauchs mit dem Innenkleber ist verfahrenstechnisch sehr vorteilhaft, da in einem gemeinsamen Verfahrensschritt der Innenkleber und der Schrumpfschlauch angesetzt werden können. Als Innenkleber kann beispielsweise ein thermoplastischer Innenkleber und insbesondere ein Innenkleber auf Polyamid-Basis zur Anwendung kommen. Beispielsweise kann ein Ethylen-Vinylacetat-Copolymer (Elastomerkleber) als Innenkleber zur Anwendung kommen. Insbesondere bei der Verwendung des thermoplastischen Innenklebers kann ein Schmelzpunkt desselben im Bereich von zirka 135 °C vorgesehen sein.The use of the shrink tube with the inner adhesive is procedurally very advantageous because in a common process step, the inner adhesive and the shrink tube can be applied. For example, a thermoplastic inner adhesive and in particular a polyamide-based inner adhesive may be used as the inner adhesive. For example, an ethylene-vinyl acetate copolymer (elastomeric adhesive) may be used as the internal adhesive. In particular, when using the thermoplastic adhesive, a melting point thereof in the range of about 135 ° C may be provided.

Bei der Erprobung des erfindungsgemäßen Kontaktierverfahrens hat sich gezeigt, dass ein sehr guter mechanischer Schutz vor Stößen, Schwingungen und dergleichen hergestellt ist. Die elektrisch leitende Verbindung ist daher dauerhaft hergestellt.In the testing of the contacting method according to the invention has been shown that a very good mechanical protection against shocks, vibrations and the like is made. The electrically conductive connection is therefore made permanently.

Zur Lösung der Aufgabe weist die erfindungsgemäße Verbindungsanordnung die Merkmale des Patentanspruchs 7 auf.To achieve the object, the connection arrangement according to the invention has the features of claim 7.
