- einer Schlauchleitung, a hose line,

- mindestens einem, vorzugsweise innerhalb der Schlauchleitung angeordneten, elektrischen, eine elektrisch isolierende Ummantelung aufweisenden Widerstandsheizdraht zur Beheizung des Fluides und - einer Verbindungsvorrichtung, die eine Kontaktierungsvorrichtung zur elektrischen Kontaktierung des Widerstandsheizdrahtes mit einer elektrischen Stromquelle sowie optional zusätzlich einer Anschlussvorrichtung zum Anschluss der Schlauchleitung an ein Fluidreservoir, z.B. einen Fluidtank, aufweist. Derartige Schlauchleitungssysteme kommen insbesondere in Scheibenwaschanlagen von Kraftfahrzeugen zum Einsatz. Die Scheibenwaschflüssigkeit besteht in der Regel aus Wasser sowie ggf. zusätzlichen Komponenten, welche die Reinigungskraft und / oder die Frostsicherheit verbessern. Damit ein derartiges Schlauchleitungssystem beim Betrieb im Winter unterhalb des Gefrierpunktes von Wasser sofort einsatzbereit ist, werden derartige - At least one, preferably disposed within the hose, electrical, an electrically insulating sheath resistance heating wire for heating the fluid and - a connecting device having a contacting device for electrically contacting the Widerstandsheizdrahtes with an electrical power source and optionally additionally a connection device for connecting the hose to a Fluid reservoir, eg a fluid tank. Such hose systems are used in particular in windscreen washer systems of motor vehicles. The windshield washer fluid usually consists of water and possibly additional components which improve the cleaning power and / or the frost resistance. In order for such a hose line system to be immediately ready for use when operating in winter below the freezing point of water, such become

Schlauchleitungssysteme regelmäßig mit einer Heizvorrichtung ausgerüstet. Eine besonders schnelle Erwärmung des zu transportierenden Fluides wird erreicht, sofern ein elektrischer Widerstandsheizdraht innerhalb der Schlauchleitung angeordnet wird. Hose line systems regularly equipped with a heating device. A particularly rapid heating of the fluid to be transported is achieved if an electrical resistance heating wire is arranged inside the hose line.

Die im Stand der Technik bekannten Schlauchleitungssysteme bestehen aus vielen Einzel- teilen. Insbesondere die Herstellung der elektrischen Kontaktierung des Widerstandsheizdrahtes ist vergleichsweise aufwendig und daher regelmäßig nicht automatisierbar. Weiterhin besteht das Problem, dass die elektrischen Kontaktstellen aus konstruktiven Gründen während des Betriebes häufig mit einer mechanischen Belastung beaufschlagt werden und daher während des Betriebs versagen können. Insgesamt sind die im Stand der Technik bekannten Schlauchleitungssysteme verbesserungsfähig. The known in the art hose assemblies consist of many individual parts. In particular, the production of the electrical contact of the resistance heating wire is relatively expensive and therefore regularly not automatable. Furthermore, there is the problem that the electrical contact points for structural reasons during operation are often subjected to a mechanical load and therefore fail during operation. Overall, the known in the art hose assembly can be improved.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Schlauchleitungs- System mit den eingangs beschriebenen Merkmalen anzugeben, welches einfach und kostengünstig herstellbar ist sowie darüber hinaus mittels eines automatisierten Verfahrens montiert werden kann. Against this background, the invention has for its object to provide a hose system with the features described above, which is simple and inexpensive to produce and beyond can be mounted by means of an automated process.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Kontaktierungsvorrichtung elektrisch leitfähige Schneidklemmen aufweist, in die Bereiche, vorzugsweise Endbereiche, des Widerstandsheizdrahtes eingeklemmt sind, wobei durch die Schneidklemmen in diesen Bereichen die isolierende Ummantelung lokal entfernt und hierdurch eine elektrische Verbindung des Widerstandsheizdrahtes mit den Schneidklemmen hergestellt ist. Erfindungsgemäß werden also für das Schlauchleitungssystem zur elektrischen Kontaktierung des Widerstandsheizdrahtes Schneidklemmen eingesetzt, welche grundsätzlich zwar bekannt sind, jedoch bislang in der Kommunikationstechnik, also zur Übertragung von elektrischen Signalen, eingesetzt wurden. Erfindungsgemäß werden diese Schneidklemmen nun jedoch zur Übertragung eines vergleichsweise großen elektrischen Stromes eingesetzt, mit dessen Hilfe die in der Schlauchleitung stehende Flüssigkeit schnell und sicher aufgetaut werden soll. Durch den Einsatz der Schneidklemmen kann die elektrische Kontaktierung des Widerstandsheizdrahtes sehr einfach erfolgen. Beim Eindrücken der Endbereiche des Widerstandsheizdrahtes in die Schneidklemmen wird an den Kontaktstellen von den Schneidklemmen die elektrisch isolierende Ummantelung des Widerstandsheizdrahtes bewusst beschädigt und damit entfernt. Aufgrund der Anpresskraft des Widerstandsheizdrahtes in der Schneidklemme wird ein sicherer elektrischer Kontakt hergestellt. Gleichzeitig mit der Montage des Widerstandsheizdrahtes in den Schneidklemmen erfolgt also eine lokale Entfernung der isolierenden Ummantelung des Widerstandsheizdrahtes und somit kann in einem einzigen Arbeitsgang sowohl die mechanische Verbindung des Widerstandsheizdrahtes mit der elektrischen Kontaktstelle als auch die Herstellung der elektrischen Verbindung mit der Kontaktstelle erfolgen. Die konstruktive Gestaltung des erfindungsgemäßen According to the invention the object is achieved in that the contacting device has electrically conductive insulation displacement terminals are clamped in the areas, preferably end portions of the Widerstandsheizdrahtes, locally removed by the insulation displacement terminals in these areas, the insulating sheath and thereby produces an electrical connection of the Widerstandsheizdrahtes with the insulation displacement terminals is. Thus, according to the invention, cutting terminals are used for the hose-line system for the electrical contacting of the resistance heating wire, which are basically known but have hitherto been used in communications technology, ie for the transmission of electrical signals. According to the invention, however, these insulation displacement terminals are now used for transmitting a comparatively large electric current, with the help of which the liquid standing in the tubing should be thawed quickly and safely. By using the insulation displacement terminals, the electrical contacting of the resistance heating can be done very easily. When pressing the end portions of the Widerstandsheizdrahtes in the insulation displacement terminals, the electrically insulating sheathing of the Widerstandsheizdrahtes deliberately damaged at the contact points of the insulation displacement wires and thus removed. Due to the contact pressure of the Widerstandsheizdrahtes in the insulation displacement terminal a secure electrical contact is made. Simultaneously with the mounting of the Widerstandsheizdrahtes in the insulation displacement thus takes place a local removal of the insulating sheath of Widerstandsheizdrahtes and thus can be done in a single operation both the mechanical connection of the Widerstandsheizdrahtes with the electrical contact point as well as the preparation of the electrical connection to the contact point. The structural design of the invention

Schlauchleitungssystems ist vergleichsweise einfach. Darüber hinaus ist die elektrische Kontaktierung sicher und schnell durchführbar. Insbesondere ist eine Automatisierung der elektrischen Kontaktierung des Widerstandsheizdrahtes möglich, da lediglich ein einfaches Eindrücken der Heizdrahtenden in die Schneidklemmen erfolgen muss. Ferner ist es mittels der Schneidklemmen möglich, im Betrieb eine sichere Zugentlastung des Widerstands- heizdrahtes sicherzustellen, da die Schneidklemmen ortsfest im Schlauchleitungssystem fixiert sind. Hose line system is relatively simple. In addition, the electrical contact is safe and fast to carry out. In particular, an automation of the electrical contacting of the Widerstandsheizdrahtes is possible, since only a simple impressions of Heizdrahtenden must be made in the insulation displacement terminals. Furthermore, it is possible by means of insulation displacement terminals, during operation, a safe strain relief of the resistance Ensure heating wire, as the insulation displacement terminals are fixed in place in the hose system.

Zweckmäßigerweise weist die Kontaktierungsvorrichtung elektrische Kontaktelemente für den Anschluss an die elektrische Stromquelle auf, die jeweils mit einer Schneidklemme verbunden sind. In einer besonders bevorzugten Ausführungsform der Erfindung sind ein Kontaktelement und eine Schneidklemme jeweils einstückig miteinander verbunden. Hierdurch wird die Herstellung des erfindungsgemäßen Schlauchleitungssystems noch weiter vereinfacht. Zweckmäßigerweise sind die elektrischen Kontaktelemente als Pins für einen Elektrostecker ausgebildet. Conveniently, the contacting device has electrical contact elements for connection to the electrical power source, which are each connected to a cutting terminal. In a particularly preferred embodiment of the invention, a contact element and a cutting clamp are each integrally connected to each other. As a result, the production of the hose line system according to the invention is further simplified. Conveniently, the electrical contact elements are designed as pins for an electrical connector.

Im Rahmen der Erfindung liegt es ferner, dass die elektrischen Kontaktelemente und / oder die mit den Kontaktelementen verbundenen Schneidklemmen eine Schmelzsicherung aufweisen, die bei Überschreitung einer bestimmten elektrischen Belastung schmilzt und die Stromversorgung des Widerstandsheizdrahtes hierdurch unterbricht. Damit wird eine Überhitzung des Schlauchleitungssystems, von der größere Schäden und auch nicht unerhebliche Gefahren ausgehen können, sicher vermieden. Im Fall einer zu starken Strombelastung werden lediglich die Schneidklemme bzw. die elektrischen Kontaktelemente geschädigt, welche einfach ausgetauscht werden können. Im Rahmen der Erfindung liegt es hier- bei insbesondere auch, dass nur der Pluspol mit einer Schmelzsicherung versehen ist und der Minuspol hingegen nicht. Zweckmäßigerweise sind die Schneidklemmen als metallisches Biegeformteil ausgebildet. Vorzugsweise weisen die Schneidklemmen ferner zumindest im Wesentlichen halbkreisförmige, mit scharfen Kanten versehene Ausnehmungen auf, in die die Bereiche des Widerstandsheizdrahtes eingeklemmt sind. In the context of the invention, it is further that the electrical contact elements and / or connected to the contact elements insulation displacement terminals have a fuse that melts when exceeding a certain electrical load and the power supply of the Widerstandsheizdrahtes thereby interrupts. This safely prevents overheating of the hose line system, which can cause major damage and considerable dangers. In the case of excessive current load, only the cutting terminal or the electrical contact elements are damaged, which can be easily replaced. In the context of the invention, it is also the case in particular that only the positive pole is provided with a fuse and the negative pole is not. Conveniently, the insulation displacement terminals are formed as a metallic bending mold part. Preferably, the insulation displacement terminals further comprise at least substantially semicircular, sharp edged recesses in which the regions of the resistance heating wire are clamped.

Im Rahmen der Erfindung liegt es auch, dass die Verbindungsvorrichtung ein Gehäuse aufweist, innerhalb dessen die Schneidklemmen angeordnet sind. Zweckmäßigerweise ist das Gehäuse mit einem Rippen aufweisenden Deckel verschlossen, wobei die ins In the context of the invention, it is also the case that the connection device has a housing within which the insulation displacement terminals are arranged. Conveniently, the housing is closed with a lid having ribs, wherein the ins

Gehäuseinnere zeigenden, vorzugsweise einstückig an den Deckel angeformten, Rippen bei der Montage des Deckels die entsprechenden Bereiche des Widerstandsheizdrahtes in die Schneidklemmen drücken. Hierdurch ist sichergestellt, dass allein durch die Montage des Deckels am Gehäuse die gewünschte elektrische Verbindung zwischen Widerstandsheizdraht, Schneidklemmen und ggf. vorhandenen elektrischen Kontaktelementen hergestellt wird. Ferner fixieren die Rippen in vorteilhafter Weise die entsprechenden Bereiche des Widerstandsheizdrahtes in den Schneidklemmen, so dass die elektrische Kontaktie- rung dauerhaft und sicher gewährleistet ist. Alternativ hierzu oder aber auch ergänzend kann das Gehäuse mit Gießharz gefüllt sein, welches die in die Schneidklemmen eingedrückten Bereiche des Widerstandsheizdrahtes fixiert und hierbei gleichzeitig elektrisch isolierend wirkt. Housing interior facing, preferably integrally formed on the lid, ribs during assembly of the lid press the corresponding areas of the resistance heating in the insulation displacement terminals. This ensures that the desired electrical connection between Widerstandsheizdraht, insulation displacement terminals and possibly existing electrical contact elements is made only by mounting the cover on the housing. Furthermore, the ribs advantageously fix the corresponding regions of the resistance heating wire in the insulation displacement terminals, so that the electrical contact permanently and safely. Alternatively, or in addition, the housing may be filled with casting resin, which fixes the depressed into the insulation displacement portions of the resistance heating wire and this case simultaneously acts electrically insulating.

Im Rahmen der Erfindung liegt es ferner, dass die Anschlussvorrichtung einen Anschlussstutzen für die Schlauchleitung sowie ein Anschlusselement zur Herstellung einer Fluidver- bindung zum Fluidreservoir aufweist. Zweckmäßigerweise weist die Verbindungsvorrichtung mindestens einen eine, vorzugsweise zwei Öffnungen aufweisenden Stopfen auf, der eine fluiddichte Hinein- und Herausführung des Widerstandsheizdrahtes in die bzw. aus der Schlauchleitung sicherstellt. Dieser Stopfen bildet zweckmäßigerweise den Übergang von Anschlussvorrichtung zur Kontaktierungsvorrichtung. Der Stopfen kann mittels Gießharz in einer entsprechenden Durchtrittsöffnung der Verbindungseinrichtung fixiert sein. Die erfindungsgemäße Lehre kommt insbesondere in Scheibenwaschanlagen für Kraftfahrzeuge zum Einsatz. Andere Anwendungsbereiche, z.B. der Transport einer Harnstoff- Wasser-Lösung, beispielsweise genormt nach DIN 70070 und CEFIC (European Chemical Industry Council), werden hierdurch jedoch nicht ausgeschlossen. Harnstoff-Wasser- Lösungen werden Verbrennungsabgasen von Motoren, insbesondere Dieselmotoren, zu- gegeben, um vor allem die Stickoxidemission zu senken und damit die immer weiter steigenden Anforderungen der Abgasvorschriften zu erfüllen. Für die Leitung der Harnstoff- Wasser-Lösung aus einem Tank zur Einspritzung in die Verbrennungsgase ist in der Regel eine Temperierungsmöglichkeit der Schlauchleitung erforderlich, weil die Harnstoff- Wasser-Lösung aufgrund ihrer chemischen Zusammensetzung den Nachteil hat, dass sie bei ca. - 1 1 °C ausflockt bzw. gefriert. In the context of the invention, it is further provided that the connection device has a connection piece for the hose line and a connection element for producing a fluid connection to the fluid reservoir. The connecting device expediently has at least one plug, preferably two openings, which ensures a fluid-tight introduction and withdrawal of the resistance heating wire into and out of the hose line. This plug expediently forms the transition from connection device to contacting device. The plug can be fixed by means of casting resin in a corresponding passage opening of the connecting device. The teaching according to the invention is used in particular in windscreen washer systems for motor vehicles. Other applications, e.g. However, the transport of a urea-water solution, for example, standardized according to DIN 70070 and CEFIC (European Chemical Industry Council), this is not excluded. Urea water solutions are added to combustion exhaust gases from engines, in particular diesel engines, in order to reduce nitrogen oxide emissions in particular and thus to meet the ever-increasing requirements of the exhaust gas regulations. For the management of the urea-water solution from a tank for injection into the combustion gases usually Temperierungsmöglichkeit the hose is required because the urea-water solution has the disadvantage due to their chemical composition, that at about - 1 1 ° C flocculates or freezes.

Die Figuren 1a und 1 b zeigen ein Schlauchleitungssystem, welches zum Transport einer Scheibenwaschflüssigkeit in einem Kraftfahrzeug eingesetzt wird. Dieses weist eine (nicht dargestellte) Schlauchleitung, einen innerhalb der Schlauchleitung schlaufenförmig angeordneten, elektrischen, eine elektrisch isolierende Ummantelung 1 aufweisenden Widerstandsheizdraht 2 zur Beheizung des Fluides und eine Verbindungsvorrichtung 3 mit einer Schneidklemmen 4 aufweisenden Kontaktierungsvorrichtung 5 zur elektrischen Kontaktie- rung des Widerstandsheizdrahtes 2 mit einer (nicht dargestellten) elektrischen Stromquelle auf. Zusätzlich besitzt die Verbindungsvorrichtung 3 eine Anschlussvorrichtung 6 zum Anschluss der Schlauchleitung an einen (nicht dargestellten) Fluidtank, vorliegend also an einen Reinigungsflüssigkeitsbehälter. Beim Ausführungsbeispiel gemäß den Fig. 1 a und 1 b wird der Widerstandsheizdraht 2 innerhalb der Verbindungsvorrichtung 3 um ca. 90° umgelenkt. Beim Ausführungsbeispiel gemäß den Fig. 2a und 2b hingegen verläuft der Wider- standsheizdraht 2 in der Verbindungsvorrichtung 3 innerhalb einer Ebene. FIGS. 1a and 1b show a hose line system which is used to transport a windshield washer fluid in a motor vehicle. This has a (not shown) hose line, a loop inside the hose arranged, electrical, an electrically insulating sheath 1 having Widerstandsheizdraht 2 for heating the fluid and a connecting device 3 with a insulation displacement terminal 4 having contacting device 5 for electrical contacting tion of Widerstandsheizdrahtes 2 with a (not shown) electrical power source. In addition, the connecting device 3 has a connecting device 6 for connecting the hose line to a (not shown) fluid tank, in the present case to a cleaning liquid container. In the embodiment according to FIGS. 1 a and 1 b, the resistance heating wire 2 is deflected within the connecting device 3 by approximately 90 °. In the embodiment according to FIGS. 2 a and 2 b, on the other hand, the resistance heating wire 2 in the connection device 3 extends within a plane.

Wie insbesondere einer vergleichenden Betrachtung der Fig. 1 a - 2b mit der Fig. 3 zu entnehmen ist, welche die in den Fig. 1a bis 2b gezeigten beiden Schneidklemmen 4 in einer dreidimensionalen Einzeldarstellung zeigt, sind in die elektrisch leitfähigen Schneidklem- men 4 die beiden Endbereiche 7 des Widerstandsheizdrahtes 2 eingeklemmt, wobei durch die Schneidklemmen 4 in diesen Endbereichen 7 die isolierende Ummantelung 1 lokal entfernt und hierdurch eine elektrische Verbindung des Widerstandsheizdrahtes 2 mit den Schneidklemmen 4 hergestellt ist. Die Kontaktierungsvorrichtung 5 weist zwei elektrische Kontaktelemente 8 für den Anschluss an die elektrische Stromquelle auf, die einstückig mit jeweils einer Schneidklemme 4 verbunden sind. Den Figuren kann ferner entnommen werden, dass die beiden elektrischen Kontaktelemente 8 als Pins für einen (nicht dargestellten) Elektrostecker ausgebildet sind. Die Pins 8 weisen jeweils eine Schmelzsicherung 9 auf, die bei Überschreitung einer bestimmten elektri- sehen Belastung schmilzt und die Stromversorgung des Widerstandsheizdrahtes 2 hierdurch unterbricht. Im Ausführungsbeispiel ist die Schmelzsicherung 9 jeweils durch eine Materialschwächung in Form einer reduzierten Materialstärke im Übergangsbereich von Pin 8 zu Schneidklemme 4 realisiert. Die beiden Schneidklemmen 4 sowie die daran As can be seen in particular from a comparative consideration of FIGS. 1 a - 2 b with FIG. 3, which shows the two insulation displacement terminals 4 shown in FIGS. 1 a to 2 b in a three-dimensional individual representation, the electrically conductive insulation displacement terminals 4 are the clamped at both end portions 7 of the resistance heating wire 2, wherein the insulating sheath 1 locally removed by the insulation displacement terminals 4 in these end regions 7 and thereby an electrical connection of the Widerstandsheizdrahtes 2 is made with the insulation displacement terminals 4. The contacting device 5 has two electrical contact elements 8 for connection to the electrical power source, which are integrally connected to a respective cutting terminal 4. The figures can also be seen that the two electrical contact elements 8 are formed as pins for a (not shown) electrical connector. The pins 8 each have a fuse 9, the melt melts when exceeding a certain electrical load and the power supply of the Widerstandsheizdrahtes 2 thereby interrupts. In the exemplary embodiment, the fuse 9 is realized in each case by a material weakening in the form of a reduced material thickness in the transition region from pin 8 to insulation displacement terminal 4. The two insulation displacement terminals 4 as well as the

angeformten Pins 8 sind jeweils als einstückiges, metallisches Blechbiegeformteil 10 aus- gebildet. Im Rahmen der Erfindung liegt es jedoch auch, dass nur der am Pluspol angeschlossene Pin 8 mit der Schmelzsicherung 9 versehen ist und der andere, am Minuspol angeschlossene Pin 8 hingegen nicht. Die beiden Schneidklemmen 4 weisen jeweils halbkreisförmige, mit scharfen Kanten 20 versehene Ausnehmungen 11 auf, in die die Endbereiche 7 des Widerstandsheizdrahtes 2 eingeklemmt sind. Die beiden Schneidklemmen 4 sind zwecks Vermeidung eines Kurzschlusses elektrisch voneinander getrennte Bauteile der Kontaktierungsvorrichtung 5 und jeweils mäanderförmig ausgebildet. Ferner sind beide Schneidklemmen 4 im Ausführungsbeispiel konstruktiv identisch. Bei der Montage wird eine der beiden Schneidklemmen 4 um 180° um die Pinachse gedreht, so dass eine spiegelbildliche Einbausituation vorliegt. formed pins 8 are each formed as a one-piece, metallic sheet metal bending molding 10. However, within the scope of the invention it is also the case that only the pin 8 connected to the positive pole is provided with the fuse 9 and the other pin 8 connected to the minus pole is not. The two insulation displacement terminals 4 each have semicircular, provided with sharp edges 20 recesses 11, in which the end portions 7 of the Widerstandsheizdrahtes 2 are clamped. The two insulation displacement terminals 4 are designed to avoid a short circuit electrically separate components of the contacting device 5 and each meandering. Furthermore, both insulation displacement terminals 4 are structurally identical in the exemplary embodiment. During assembly, one of the two cutting clamps 4 is rotated by 180 ° about the pin axis, so that there is a mirror-image installation situation.
