- the invention relates to a hose line system, in particular for the transport of an aqueous fluid in a motor vehicle, with
- a Fluid reservoir eg a fluid tank.
- 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
- 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.
- the known in the art hose assemblies consist of many individual parts.
- the production of the electrical contact of the resistance heating wire is relatively expensive and therefore regularly not automatable.
- the electrical contact points for structural reasons during operation are often subjected to a mechanical load and therefore fail during operation.
- the known in the art hose assembly can be improved.
- 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.
- 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 cherriessSchdrahtes, locally removed by the insulation displacement terminals in these areas, the insulating sheath and thereby produces an electrical connection of the lovedsSchdrahtes with the insulation displacement terminals is.
- 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.
- 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.
- Hose line system is relatively simple.
- the electrical contact is safe and fast to carry out.
- an automation of the electrical contacting of thelvessSchdrahtes is possible, since only a simple impressions of Schudrahtenden must be made in the insulation displacement terminals.
- the contacting device has electrical contact elements for connection to the electrical power source, which are each connected to a cutting terminal.
- a contact element and a cutting clamp are each integrally connected to each other.
- the electrical contact elements are designed as pins for an electrical connector.
- 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 lovedsSdrahtes 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.
- the insulation displacement terminals are formed as a metallic bending mold part.
- the insulation displacement terminals further comprise at least substantially semicircular, sharp edged recesses in which the regions of the resistance heating wire are clamped.
- connection device has a housing within which the insulation displacement terminals are arranged.
- the housing is closed with a lid having ribs, wherein the ins
- 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.
- 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.
