DESCRIPCIONDESCRIPTION
Revestimiento por extrusion de una rejilla estampada con un plastico con alta velocidad de contraccionExtrusion lining of a grid stamped with a plastic with high contraction speed
La invencion se refiere a una interfaz hermetica al agua longitudinalmente entre un primer espacio, en el que imperan condiciones de entorno rigurosas en particular con humedad, agua o similares, y un segundo espacio en su mayor parte seco, de acuerdo con las caractensticas del respectivo preambulo de las reivindicaciones independientes. En particular se refiere la invencion a una interfaz hermetica al agua longitudinalmente entre un carter y un compartimento del motor de un vehnculo, en particular de un automovil.The invention relates to a longitudinally water tight interface between a first space, in which rigorous environmental conditions prevail in particular with humidity, water or the like, and a second space mostly dry, in accordance with the characteristics of the respective preamble of the independent claims. In particular, the invention relates to a water tight interface longitudinally between a crankcase and an engine compartment of a vehicle, in particular of a car.
Se sabe que la carcasa del conectador enchufable se moldea por inyeccion a partir de un plastico, revistiendose por extrusion los componentes de contacto y / o la al menos una rejilla estampada por el plastico. Al mismo tiempo se reviste por extrusion tambien el extremo de la conduccion electrica o de las varias conducciones electricas con el plastico de la carcasa del conectador enchufable para conseguir de esta manera la hermeticidad al agua longitudinal.It is known that the plug-in connector housing is injection molded from a plastic, the contact components and / or at least one grid stamped by the plastic being extrusion coated. At the same time, the end of the electrical conduction or of the various electrical conduits is also coated by extrusion with the plastic of the plug-in connector housing in order to achieve longitudinal water tightness in this way.
Por tanto, la invencion se basa en el objetivo de proporcionar una interfaz hermetica al agua longitudinalmente mejorada asf como un procedimiento para su fabricacion.Therefore, the invention is based on the objective of providing a longitudinally improved water tight interface as well as a process for its manufacture.
Este objetivo se soluciona mediante las caractensticas de las reivindicaciones independientes.This objective is solved by the characteristics of the independent claims.
Este objetivo se soluciona de acuerdo con el dispositivo debido a que la carcasa esta formada de un plastico con alta velocidad de contraccion. Esto tiene la ventaja de que la carcasa tras su fabricacion (y eventualmente tambien ya durante su fabricacion) se sujeta muy fuertemente allf en la zona en la que entra en contacto con el revestimiento aislante de la conduccion, para establecer una conexion mtima con la que se consigue la hermeticidad al agua longitudinal necesaria.This objective is solved according to the device because the housing is formed of a plastic with high contraction speed. This has the advantage that the carcass after its manufacture (and eventually also during its manufacture) is held very tightly there in the area where it comes into contact with the insulating coating of the conduit, to establish a minimum connection with which the necessary longitudinal water tightness is achieved.
En un perfeccionamiento de la invencion es de manera ventajosa la carcasa una pieza moldeada por inyeccion. Debido a ello puede fabricarse la carcasa de manera reproducible precisamente en una produccion en serie en altas cantidades de manera rapida, sencilla, economica y con la precision necesaria. Para ello se introducen los elementos de la interfaz, que deban rodearse por la carcasa, en un molde de inyeccion configurado de manera correspondiente (al menos de varias partes) y se introduce el plastico con alta velocidad de contraccion en el molde de inyeccion, en particular se inyecta con presion. A este respecto ha de prestarse atencion logicamente a que aquellas zonas que deben conectarse con el plastico de alta velocidad de contraccion, tambien se conectan con este plastico inyectado. Las zonas que no deben rodearse por este plastico, tales como por ejemplo los componentes de contacto, pueden disponerse dentro del molde de inyeccion o tambien fuera del molde de inyeccion de modo que se impida que se conecten estas con el plastico inyectado.In an improvement of the invention, the housing is advantageously an injection molded part. Due to this, the casing can be manufactured in a reproducible manner precisely in a series production in high quantities quickly, easily, economically and with the necessary precision. For this purpose, the interface elements, which must be surrounded by the housing, are introduced in a correspondingly configured injection mold (at least several parts) and the plastic with high contraction speed is introduced into the injection mold, in particular is injected with pressure. In this regard, attention should be paid logically to those areas that must be connected with the high-speed plastic of contraction, also connect with this injected plastic. The areas that should not be surrounded by this plastic, such as for example the contact components, can be arranged inside the injection mold or also outside the injection mold so as to prevent them from connecting with the injected plastic.
De acuerdo con la invencion se usa una combinacion de material, en la que el plastico del revestimiento aislante de la conduccion es un plastico de ETFE (etileno-tetrafluoroetileno) y el plastico de la carcasa es un plastico de PBT (poli(tereftalato de butileno)). Esta combinacion de material tiene la ventaja especial de que garantiza la hermeticidad al agua longitudinal tambien en grandes intervalos de temperatura, en particular de menos 40 grados Celsius a mas 150 grados Celsius, tal como debe garantizarse en particular en la aplicacion en vehnculos. Al mismo tiempo tiene esta combinacion de material o cada plastico usado individual la ventaja de que este resiste condiciones de entorno rigurosas. Segun esto pueden mencionarse por ejemplo humedad, vibraciones, solicitaciones mecanicas tales como traccion y presion, asf como en la aplicacion en vehnculos por ejemplo agua salada y aceite pulverizado y condiciones de entorno comparables.According to the invention a combination of material is used, in which the plastic of the conductive insulating coating is an ETFE (ethylene-tetrafluoroethylene) plastic and the housing plastic is a PBT (poly (butylene terephthalate) plastic )). This combination of material has the special advantage that it guarantees longitudinal water tightness also at large temperature ranges, in particular from less than 40 degrees Celsius to more than 150 degrees Celsius, as must be guaranteed in particular in application in vehicles. At the same time, this combination of material or each individual plastic has the advantage that it resists stringent environmental conditions. According to this, humidity, vibrations, mechanical stresses such as traction and pressure can be mentioned, for example, as well as in the application in vehicles such as salt water and pulverized oil and comparable environmental conditions.
Para el aumento de la hermeticidad al agua longitudinal deseada presenta la zona, en la que el componente de contacto esta dispuesto en el extremo del conductor electrico, una estampacion. Como ejemplo se menciona en este caso que el conductor electrico de la conduccion en su extremo se libera (se deja al descubierto) del revestimiento aislante, de modo que esta zona aislada puede llevarse a conexion con una zona de contacto del componente de contacto. En el area de la zona de contacto se conecta el extremo del conductor electrico con el componente de contacto al menos electricamente, preferentemente sin embargo mecanica y electricamente. La conexion electrica se realiza por ejemplo mediante soldadura, termosoldadura, pegado o similares. Una fijacion mecanica se realiza por ejemplo mediante un encogimiento, en el que el extremo del conductor electrico se fija por aletas de encogimiento de una conexion de encogimiento. Eventualmente puede pensarse tambien en este caso en soldar o termosoldar o similar, despues de o antes de realizar el encogimiento, el conductor electrico en la zona de contacto con el componente de contacto. Esta zona de contacto preparada de esta manera tal como se ha descrito anteriormente se dota de una estampacion, que esta configurada por ejemplo como una estampacion plana, una estampacion, en forma de ranuras y/o almas o similares. Tambien esta zona de la estampacion se rodea con el plastico de alta velocidad de contraccion, que forma la carcasa, de modo que debido a esta conformacion aumenta la superficie que esta a disposicion en el area de contacto (zona de contacto) para mejorar debido a esta superficie aumentada la hermeticidad al agua longitudinal.For the increase of the desired longitudinal water tightness, the area is presented, in which the contact component is arranged at the end of the electric conductor, a stamping. As an example, it is mentioned in this case that the electrical conductor of the conduit at its end is released (exposed) from the insulating coating, so that this insulated zone can be brought into connection with a contact zone of the contact component. In the area of the contact zone the end of the electrical conductor is connected to the contact component at least electrically, preferably mechanically and electrically, however. The electrical connection is made, for example, by welding, heat welding, bonding or the like. A mechanical fixation is carried out, for example, by means of a shrink, in which the end of the electric conductor is fixed by shrink fins of a shrink connection. Eventually, in this case, it is also possible to consider welding or heat-welding or the like, after or before shrinking, the electric conductor in the contact area with the contact component. This contact area prepared in this manner as described above is provided with a stamping, which is configured for example as a flat stamping, a stamping, in the form of grooves and / or souls or the like. Also this area of the stamping is surrounded by the high-speed plastic of contraction, which forms the housing, so that due to this conformation the surface that is available in the contact area (contact area) increases to improve due to this surface increased the water resistance to longitudinal water.
De acuerdo con el procedimiento esta previsto para la fabricacion de una interfaz hermetica al agua longitudinalmente que la carcasa se forme de un plastico con alta velocidad de contraccion en un procedimiento de moldeo por inyeccion. Mediante esto resultan las mismas ventajas, tal como se han expuesto ya anteriormente. ElAccording to the procedure, it is planned for the manufacture of a water-tight interface longitudinally so that the housing is formed of a plastic with high contraction speed in an injection molding process. This results in the same advantages, as discussed above. He

procedimiento de moldeo por inyeccion tiene la ventaja de que la carcasa puede fabricarse de manera reproducible precisamente en una produccion en serie con altas cantidades de manera muy sencilla, rapida, economica y con la precision necesaria. Ademas es posible una multiplicidad de geometnas de la carcasa, dado que dependiendo de la geometna de la carcasa deben incorporarse unicamente otros moldes de inyeccion (moldes) en una maquina de moldeo por inyeccion. El uso del plastico con alta velocidad de contraccion tiene en este caso igualmente la ventaja de que consigue durante el proceso de moldeo por inyeccion y/o tras la fabricacion de la carcasa acabada la conexion mtima deseada con el revestimiento aislante de plastico para la obtencion de la hermeticidad al agua longitudinal deseada.Injection molding process has the advantage that the housing can be reproducibly manufactured precisely in a series production with high quantities in a very simple, fast, economical manner and with the necessary precision. In addition, a multiplicity of carcass geometries is possible, since depending on the carcass geometry only other injection molds (molds) must be incorporated into an injection molding machine. In this case, the use of plastic with high contraction speed also has the advantage that during the injection molding process and / or after the fabrication of the finished housing, the desired minimum connection with the plastic insulating coating is obtained to obtain the desired longitudinal water tightness.
Una aplicacion especialmente ventajosa de la interfaz hermetica al agua longitudinalmente de acuerdo con la invencion se observa en la aplicacion en vehnculos. En este caso ha de observarse de manera especialmente ventajosa la aplicacion de la interfaz hermetica al agua longitudinalmente con la carcasa, que esta formada de un plastico con alta velocidad de contraccion, entre un carter y un compartimento del motor de un vehnculo. En esta aplicacion se encuentran tanto altas temperaturas (temperatura del aceite en el funcionamiento del vehnculo de aproximadamente 90 grados Celsius o eventualmente tambien superior a esto) asf como condiciones de entorno rigurosas (tal como humedad, agua sucia y agua salada en el compartimento del motor y sobre todas las cosas tambien una alta diferencia de temperatura entre el carter y el compartimento del motor).An especially advantageous application of the water-tight interface longitudinally according to the invention is observed in the application in vehicles. In this case, it is especially advantageous to observe the application of the hermetic interface to the water longitudinally with the housing, which is formed of a plastic with high speed of contraction, between a crankcase and an engine compartment of a vehicle. In this application there are both high temperatures (oil temperature in the operation of the vehicle of approximately 90 degrees Celsius or possibly higher than this) as well as stringent environment conditions (such as humidity, dirty water and salt water in the engine compartment and above all also a high temperature difference between the crankcase and the engine compartment).
De manera complementaria se describe la invencion aun tal como sigue.In a complementary manner the invention is described even as follows.
La interfaz hermetica al agua longitudinalmente se forma por un conectador enchufable, que puede enchufarse con un correspondiente contraconectador enchufable. El conectador enchufable (y tambien el contraconectador enchufable) presentan componentes de contacto que estan dispuestos en el extremo de una conduccion. De manera correspondiente a los requerimientos de la transmision de senales, tensiones o similares con el conectador enchufable esta presente en numero correspondiente o bien una conduccion o estan presentes en numero correspondiente varias conducciones. Las conducciones presentan un conductor interno electricamente conductor, que esta dotado frente a las influencias externas y para la proteccion contra cortocircuitos de un revestimiento aislante. Con el extremo de la conduccion electrica esta conectado de manera adecuada un componente de contacto, tal como un enchufe, un casquillo o similar. El componente de contacto puede estar configurado tambien como alternativa en forma de una rejilla estampada, siendo concebible que con dos o varias rejillas estampadas se conecten piezas de construccion electricas o electronicas entre sfThe longitudinally water tight interface is formed by a plug-in connector, which can be plugged in with a corresponding plug-in counter connector. The plug-in connector (and also the plug-in counter-connector) have contact components that are arranged at the end of a pipe. Corresponding to the requirements of the transmission of signals, voltages or the like with the plug-in connector is present in corresponding number or one conduit or several conduits are present in corresponding number. The pipes have an electrically conductive internal conductor, which is equipped against external influences and for the protection against short circuits of an insulating coating. A contact component, such as a plug, a socket or the like, is suitably connected to the end of the electrical conduction. The contact component may also be configured as an alternative in the form of a stamped grid, it being conceivable that two or more stamped racks connect electrical or electronic construction pieces to each other.
El conectador enchufable presenta por su parte una carcasa, estando dispuesta en la carcasa una camara de contacto para los componentes de contacto o la al menos una rejilla estampada.The plug-in connector has a housing on the other hand, a contact chamber for the contact components or the at least one stamped grid being arranged on the housing.
La carcasa del conectador enchufable esta configurada por su contorno externo de manera que por un lado puede acoplarse con el contraconectador enchufable y por otro lado puede estar configurado y puede ser adecuado para que se fije en o a una pieza de construccion del vehnculo. En particular en el ejemplo de aplicacion del carter / compartimento del motor presenta el conectador enchufable un enclavamiento integrado en la carcasa del carter (bedplate, bancada).The plug-in connector housing is configured by its external contour so that on the one hand it can be coupled with the plug-in connector and on the other hand it can be configured and can be adapted to be fixed in or to a vehicle construction part. In particular, in the example of the application of the crankcase / engine compartment, the plug-in connector has an interlock integrated in the crankcase housing (bedplate, bed).
De acuerdo con la invencion esta previsto para la hermeticidad al agua longitudinal mejorada que la hermeticidad se consiga mediante revestimiento por extrusion del componente de contacto o de la al menos una rejilla estampada con zona estampada con un plastico con alta velocidad de contraccion. Debido a ello puede conseguirse, en comparacion con plasticos con baja velocidad de contraccion, una hermeticidad al agua longitudinal claramente mejorada, presentando el plastico propuesto en el presente documento con alta velocidad de contraccion de manera ventajosa tambien requerimientos adicionales de la temperatura, de la estabilidad frente a los medios y similares.According to the invention, it is provided for improved longitudinal water tightness that the tightness is achieved by extrusion coating of the contact component or of the at least one stamped grid with area stamped with a plastic with high shrinkage speed. Due to this, a clearly improved longitudinal water tightness can be achieved in comparison with plastics with low contraction speed, presenting the plastic proposed herein with high contraction speed advantageously also additional temperature, stability requirements in front of the media and the like.
En particular para la aplicacion en vehnculos debe poder representarse un intervalo de temperatura de menos 40 grados Celsius a mas 130 grados Celsius (o tambien mas alla de esto) para el plastico con alta velocidad de contraccion. La estabilidad frente a los medios se refiere en particular a la resistencia frente a medios agresivos tales como combustible, aceite, aceite pulverizado, agua salada, productos de limpieza y similares. Ademas debe cumplir el plastico con alta velocidad de contraccion tambien una alta exigencia de vibracion.In particular for application in vehicles, a temperature range of less than 40 degrees Celsius to more than 130 degrees Celsius (or also beyond this) must be represented for plastic with high contraction speed. Media stability refers in particular to resistance to aggressive media such as fuel, oil, spray oil, salt water, cleaning products and the like. You must also meet the plastic with high speed of contraction also a high requirement of vibration.
De acuerdo con la invencion esta constituido el revestimiento exterior de la al menos una conduccion electrica de material de ETFE (etileno-tetrafluoroetileno), siendo el plastico con alta velocidad de contraccion un plastico de PBT (poli(tereftalato de butileno).In accordance with the invention, the outer coating of the at least one electrical conduit of ETFE material (ethylene-tetrafluoroethylene) is constituted, the plastic with high contraction rate being a plastic of PBT (poly (butylene terephthalate).
