Description

Beskyttelse med krybestrøm til kabler i et kabelbundt Nærværende opfindelse angår en beskyttelse mod krybestrøm, der reducerer væskevandring gennem kabler, i henhold til overbegrebet i krav 1, samt et system til efterbehandling af udstødningsgas med en tilsvarende beskyttelse mod krybestrøm Ϊ kabler.BACKGROUND OF THE INVENTION This invention relates to a creep flow protection that reduces fluid migration through cables according to the concept of claim 1, and a exhaust gas after-treatment system with a corresponding creep flow Ϊ cable protection system.

ividtorkøretøjskomponenter, som for eksempel systemer til efterbehandling af udstødningsgasser, består af forskellige enkelte elementer, der styres indbyrdes elektrisk med en styreenheef der enten er udviklet specielt til den pågældende enhed, eller som befinder sig centralt i en mo-torstyreenhe#i:J>en elektriske kontakt mellem styreenheden og de enkelte elektriske komponenter i enheden til efterbehandling af udstødningsgas løber via elektriske kabler i et kabelbundt. Systemer til brænd-: stofindsprøjtning, hvis indsprøjtningsventlief er forbundet med en motorstyreenhed via kabler, er opbygget på lignende vis- Desuden har ventiler med en lignende opbygning forbindelse til motorstyreenheder, der for eksempel styrer knastakselstyringen. Elementerne arbejder med korrosive væskif/ dér for nogles vedkommende kan vandre. Således er det i forsøg for eksempel i forbindelse med ureaopløsninger blevet konstateret, at de uréa krysta l ler der ud krystalliseres ved reaktion med luft, kan yahdré Videre i kabierne Og således tilbagelægge strækninger pi over 6 meter. Krystallerne kommer såledee i tidens løb ind i styreenheden, selv hvis den befinder sig langt væk. Dererogsa blevet konstateret lignende vandringer i forbindelse med olieholdige væsker som for eksempel benzin eller diesefbmendstpf efter flere hundred driftstimer.Individual vehicle components, such as exhaust after-treatment systems, consist of various individual elements that are electrically controlled with a control lever that is either designed specifically for that unit, or which is centrally located in a motor control unit: electrical contact between the control unit and the individual electrical components of the exhaust aftertreatment unit runs via electric cables in a cable bundle. Fuel injection systems, whose injection valves are connected to a motor control unit via cables, are similarly constructed. In addition, valves with a similar structure are connected to motor control units which control the camshaft control, for example. The elements work with corrosive liquid shifts / there for some people can wander. Thus, for example, in experiments with urea solutions, it has been found that the urea crystals which crystallize out by reaction with air, can yahdré Further in the cabins And thus cover stretches of over 6 meters. The crystals thus enter the control unit over time, even if it is far away. Also, similar migrations have been found in connection with oily liquids such as gasoline or diesel fuel after several hundred hours of operation.

Det er Især vigtigt at undgå enhver form for risici på tunge lastbiler, der transponerer farligt go Det skal på sikker vis forhindres, at styreenheder ikke fungerer fuldstændig upåklageligt, eller at der endda sker kortslutninger i forbindelser mellem enkelte ledere eller enkelte årer i et kabelbundt. Dette gøres bedst ved så tæt som muligt på indkrybnings-stedet at forhindre den vandrende væske i at foretage enhver bevægelse fremad.It is Particularly Important to Avoid Any Hazards on Heavy Trucks Transposing Dangerously Go It must be safely prevented that control units do not function completely impeccably or that even short circuits occur in connections between individual conductors or individual veins in a cable bundle. This is best done by preventing the moving fluid as closely as possible at the point of entry to any forward movement.

E>^t er således oplagt at hindre væsken i at vandre ved at anbringe tætninger ved de elektriske kontakter på motorstyringens enhed til efterbehandling af udstødningsgas eller på indsprøjtningsventilen. En lang række konstruktionsmæssige forholdsregler har ganske vist opnået forsinkelser, men langvarige hindringer var ikke mulige.Thus, it is obvious to prevent the fluid from migrating by placing seals at the electrical contacts on the engine control unit for exhaust gas treatment or the injection valve. A large number of structural measures have delayed, but long-term obstacles were not possible.

tinder den videre søgning efter en beskyttelse mod krybestrøm for kabler og enkelte beklædte ledere i sådanne kabler for at kunne hindre væsker, herunder især korrosive væsker som urea, i at vandre, søgtes der efter løsninger med vid Udbredelse. Dé endemuffer der fås hos mange etforhan diere, er beskrevet nøjere i den tyske standard DIN 46 341 del 1 fra februar 1977. Der foreslås her to gængse former inden for i so lerings muffer, det isolerer lederne Udadtil, form A og form Ek Sådanne endemuffer tilbydes for eksempel som crimp-samlemuffer, Crimp-samlemuffer har været kendt inden for bilkonstruktion i flere årtier. Forsøg med gængse crimp-samlemuffer, der blev brugt som vinklet forbindelsesled mellem to kabler der blev forbundet med hihanden, kunne heller ikke forhindre de korrosive væsker i at vandre. Laboratorieundersøgelser foretaget af patentansøgeren har vist, at væsken fortsatte med at krybe selv véd en flad m eta i - m eta I - kqn ta kt.For example, the further search for protection against creep flow for cables and single coated conductors in such cables to prevent liquids, especially corrosive liquids such as urea, from wandering, was sought for solutions with widespread use. The end sleeves that are available from many ethanol animals are described in more detail in German standard DIN 46 341 part 1 of February 1977. Here two common forms are proposed in insulation sleeves, which isolates the external conductors, form A and form Ek Such end sleeves offered for example as crimp assembly sleeves, Crimp assembly sleeves have been known in the field of automotive construction for several decades. Also, experiments with common crimp joints used as an angled connector between two cables connected to the hand could not prevent the corrosive fluids from migrating. Laboratory studies by the patent applicant have shown that the fluid continued to crawl even at a flat m eta i - m eta I - kqn ta kt.

fra den tyske brugsmodel DE 20 2005 002 544 U1 kendes der en crimp-samlemuffé, dér består af ét grundelement, i hvis midte der bibeholdes en væg meljern be to blindhuller, der bores fra begge sider.from the German utility model DE 20 2005 002 544 U1 there is known a crimp joint sleeve, which consists of one basic element, in the middle of which is retained a wall of iron, two blind holes drilled from both sides.

Før at kunne tilbyde yderligere funktionér i fotbindéise med elektriske kontaktforbindéjsesstykker findes der j DE 1 148 614 og CH 359182 mulighed for at Optage tapper, der jøbér pi tværs af åreretningen, i muffer Plastiktappen i fig, 8 t DE 1 148 614 fungerer Som holdéstift, mens metaltappen i fig, 1 i CH 359182 tjener til at skabe kontakt for røl I esp idser.Before being able to offer additional functions in foot binding with electrical contact connectors, there is a possibility of incorporating pins that jib across the year in the sleeves. The plastic tab in Fig. 8 t DE 1 148 614 functions as holding pin, while the metal pin of Fig. 1 of CH 359182 serves to make contact for rolls in esp ids.

Pa anvendelsesområder, hvor der ønskes vandtætte klemfofhihdelse, er der fra DE 42 37 900 Al kendskab til, at derfor at forhindre vandtilførsel kan lægges et organisk ta^hingsmate^ som mel- lemlæg rundt dm isoleringskappen under klemfligene.In applications where waterproof clamping joints are desired, from DE 42 37 900 Al it is known that, therefore, to prevent water supply, an organic fabric mat can be laid as a spacer around the insulating sheath under the clamping tabs.

Dét gælder altså om at skabe en beskyttelse mod krybestrøm i kabler, hvis ydre de relevante sped a I vær ksteder hurtigt kan blive fortrolige med, og som sikrer at væske i løbet af tusinde driftstimer hindres i at vandre videre til styreenheden, der er placeret længere væk. Der bør desuden vælges en løsning, der kan eftermonteres på enheder til efterbehandling af udstødningsgas, der allerede er i brug eller som er i kundernes besiddelse.This applies to creating protection against creep flow in cables whose outer spaces can quickly become familiar with and ensure that fluid over a thousand operating hours is prevented from moving on to the control unit, which is located longer away. In addition, a solution should be chosen that can be retrofitted to exhaust gas treatment units that are already in use or that are in the customer's possession.

Opgaven ifølge opfindelsen består altså i at skabe en beskyttelse mod krybestrøm j kabler, der forhindrer at korrosive væsker, som for eksempel en ureaopiøsning, vandrer i kabler på motorkøretøjer.Thus, the task of the invention consists in providing protection against creep flow j cables which prevent corrosive liquids, such as a urea solution, from traveling in cables on motor vehicles.

Dette løses ifølge opfindelsen med en beskyttelse mod krybestrøm ifølge krav 1,1 kravene 4 øg 7 fremstilles en velegnet anordning i en enhed til efterbehandling af udstødningsgasser. En tilsvarende anvendelse beskrives i krav 8.This is solved according to the invention with a protection against creep flow according to claim 1.1, claims 4 and 7, a suitable device is produced in an exhaust gas treatment unit. A similar use is described in claim 8.

Den komPOidhfe der betegnes som beskyttelse mod krybestrøm i kabler, Skal hindfe væsken, der findes i en del af motorkøretøjet, i at vandre gennem et elektrisk forbindelseskabe!. Selve kablet er i det mi ndste en leder, så at sige en åre, der er beklædt. Beskyttelsen mod krybestrøm i kabler er orienteret efter gængse erimp-samlemuffer, der har kabelformede: kontaktomslutninger med åbninger i to ender. Afsnitsvist fremtræder de søm en elektrisk ledende muffe.The composite termed protection against creep current in cables Should prevent the fluid contained in any part of the motor vehicle from traveling through an electrical junction box !. The cable itself is at least a conductor, so to speak, a vein that is clad. The protection against creep current in cables is oriented to common erimp assembly sleeves having cable-shaped: contact enclosures with openings at two ends. By section, the seams appear in an electrically conductive sleeve.

Beskytteisen mod krybestrøm i kabler, der findes 1 et kabelbundt, har i sit indre et elastisk spærreeiement, fortrinsvist omtrent i midten. Kablets enkelte indførte årer kan maksimalt føres frem til det efastiske ie-héfspærreeleméht. ledersp&mreelementet, der for eksempel kan bestå af ethylen-propylen-dien-gumm! (EPDM)/hydreret nitnlgumm» (H-NBR), berører i enderne kablets ledere og afslutter derved kablets ende. Le-dérapaerreeieirnen udgør dermed en spærre ved kontaktberøringen mellem metal og ethy len-pro py I en -di e n -g u m m i (EPDM)/h yd reret nitril-gummiThe protection ice against creep current in cables found in a cable bundle has in its interior an elastic locking element, preferably approximately in the middle. The individual inserted conductors of the cable can be fed up to the ephemic ie-lock-blocking element to a maximum. the conductor & element which may, for example, consist of ethylene-propylene-diene rubber! (EPDM) / hydrated rubbers (H-NBR), touch the ends of the cable conductors and thereby terminate the cable end. Thus, the Le-dérapaerreeirnen constitutes a barrier in the contact contact between metal and ethylene propylene in a -di e n -g u m m i (EPDM) / h nitrile rubber.

Beskyttelsen mod krybestrøm i kabler har to åbninger, i hvilke der kan indføres enkelte beklædte årer fra et kabel. Der sker en køntaktomslut-ning pi begge sider af de enkelte indførte årer. En formsluttende forbindelse mellem beskyttelsen mod krybestrøm i kabler og årerne forhindrer, at årerne glider ud af beskyttelsen mod krybestrøm i kabler.The protection against creep current in cables has two openings in which single coated veins can be inserted from a cable. There is an enclosing on both sides of the individual introduced veins. A form-fitting connection between the protection against creep flow in cables and the veins prevents the veins from slipping out the protection against creep flow in cables.

Det elastiske iederspaerreelernent sidder selvsiddende i radial retning mellem de enkelte årer. Lederspærree!ementet berører kontaktomslut-ningen fuldstændigt. Lederspærreeiementet ligger langs hele omkredsen i kontaktpmslutningen. Led erspærreelementets opgave er at Opbygge en kontaktafbrydelse som spærring for vaeskekrybning i åreretningen. Den korrosive væske der vandrer ind i det beklædte kabel, kan derved trænge frem indtil lederspærreeiementet. Fra lederspærreeiementet opbygges der en pålidelig soærre for den korrosive væske.The elastic spring locking element is self-seated in the radial direction between the individual veins. The conductor locking element completely contacts the contact envelope. The conductor locking member is located along the entire circumference of the contact connection. The task of the locking block element is to Build a contact switch as a barrier for liquid creep in the year. The corrosive liquid which enters the sheathed cable can thereby penetrate up to the conductor locking element. From the conductor locking element, a reliable special is built up for the corrosive liquid.

Det er en fordel, hvis skilléelementet indbygges på fordelagtige stedør i kabel bundtet. Dette kan også ske på et senere tidspunkt. Det eksisterende kabeibundt kan i så fald blive i motorkøretøjet. På foreskrevne Stider skal kabelbundtet kun skilles ad. Skilleelementet indbygges mellem en komponent, hvori der strømmer et medium til efterbehandling af udstødningsgasser; for eksempel på ureabasis, som for eksempel en doseringsenhed eller en pumpe eller et mellemlager, og en elektrisk styre-enhed for at forbinde den elektriske styreenhed, der kan være udstyret med en mikrocontroller, elektrisk med mediet til efterbehandling af udstødningsgasser, mens det fluidtsk er skilt fra komponenterne.It is an advantage if the partition element is built into an advantageous locator in the cable bundle. This can also happen at a later date. In this case, the existing cab bundle may remain in the motor vehicle. At the prescribed times, the cable bundle should only be disassembled. The separating element is incorporated between a component in which a medium is used to exhaust exhaust gases; for example, on a urea basis, such as a metering unit or pump or intermediate storage unit, and an electrical control unit for connecting the electrical control unit, which may be equipped with a microcontroller, electrically with the exhaust gas treatment medium while it is fluid. separated from the components.

Beskyttelsen mod krybestrøm i kabler, der er udformet som beskyttelse mod krybestrøm i enkelte årer, er betrukket med et isolerende lag på den udvendige overflade. Selvom beskyttelsen mod krybestrøm i kabler tjruges i motorkøretøjssystemer med lav spænding, fx under 63 V, altsa ved 12 Vi, 24 V eller 48 V, og ikke udgør nogen fare for mennesker der kommer 1 berøring med den, ydes der således en yderligere sikkerhed fx rhod gnisttændinger. På enderne af beskyttelsen mod krybestrøm i kabler er der udkrænget ansatser. Mellem ansatserne findes der en mel· lemleklaedning der er beklædt med isolerende materiale, og som afsluttes af ansatserne, der ligeledes kan være beklædte.The protection against creep flow in cables, which are designed to protect against creep flow in individual veins, is covered with an insulating layer on the outside surface. Although the protection against creep current in cables is used in low-voltage motor vehicle systems, eg below 63 V, ie at 12 Vi, 24 V or 48 V, and does not pose a danger to people who come into contact with it, an additional security is provided e.g. rhod spark ignition. At the ends of the protection against creep current in the cables there are creased stents. Between the abutments there is an intermediate garment covered with insulating material, which is finished by the abutments, which may also be coated.

Ifølge et udførelséséksémpél befinder der sig mindst en indbugtning, eventuelt også flere indbugtninger, i centrum af den midterste muffe, der peger i retning af muffens akse. Indbugtningerne ser ud som kærver. indbugtningerne forbedrer lederspærreelementets spærrevirkning ved at fastlægge en positionering og derved samtidig hindre ledefspær-reelementet i at forskubbe sig.According to one embodiment, at least one indentation, possibly also several indentations, is located in the center of the middle sleeve pointing in the direction of the axis of the sleeve. The indentations look like gnomes. the indentations enhance the locking element's locking action by determining a positioning and thereby preventing the locking element from shifting.

Når beskyttelsen mod krybestrøm i kabler, der kan omfatte flere beskyttelser mod krybestrøm i kabler indbyrdes forbundettil en pakke, indbygges, bevirker den en opdeling af motorkøretøjets enkelte områder. Eter opstår et område, i hvilket væsken cirkulerer øg køn diffundere. Et andet område gælder som fluidisk adskilt fra mediet til efterbehandling af udstødnibisgis.When the protection against creep current in cables, which may comprise several protection against creep current in cables interconnected to a package, is incorporated, it causes a division of the individual areas of the motor vehicle. Ether arises an area in which the fluid circulates increasing sex diffuse. Another area applies as fluid separated from the medium for the exhaust nib gas finishing.

Beskyttelsen mod krybestrøm i kabler ser ud som en aflang muffe, dér bthSltitter årerne fast, og som bringer det tilførende og afledende kabel elektrisk i forbindelse med hinanden, mens et elastisk spærreelement i muffens centrale område sikrer en yaeskemaessig adskillelse.The protection against creep current in cables looks like an elongated sleeve where the bthSltitter veins firmly, which electrically connect the supplying and conducting cable, while an elastic locking element in the central area of the sleeve ensures a yaw-shaped separation.

En lettere forståelse af opfindelsen kan opnås ved hjælp af de vedlagte tegnirtger, hvøraf fig, 1 viser en klassiske endemuffe, fig. 2 viser en skematisk, fremstilling af anvendelsesområdet for en beskyttelse rnod krybestrøm i kabler, fig, 3 viser en første udførelsesform af en beskyttelse mod krybestrøm i kabler, fig. 4 viser en yderligere udførelsésform af en beskyttelse mod krybe-strøm i: kabler med talrige enkelte årer, der hver især er beklædte og således dan her én leder méd flere årer, fig. 5 viser én yderligere udføreisesform af en beskyttelse mod krybe strøm i kabier>: fig. 6 viser en ddførelsesform i henhold til fig, 5 med enkelte kabler.A better understanding of the invention can be obtained by means of the accompanying drawings, in which Fig. 1 shows a classic end sleeve; Fig. 2 is a schematic representation of the application of a protection against creep current in cables; Fig. 3 shows a first embodiment of a protection against creep flow in cables; Fig. 4 shows a further embodiment of a protection against creep current in: cables having numerous single cores, each of which is clad and thus forms one conductor with several cores; 5 shows one further embodiment of a protection against creeping current in cabs>: fig. 6 shows an embodiment of FIG. 5 with single cables.

Fig. 1 viser en allerede kendt endemuffe, der også anvendes på motor-køretøjsomfåclet, dg som kan erimpes på kablerne i et kabelbundt ved hjåblp af en crimp-samlemuffe for på den mide at bringe enderne af en åre i kontakt med enderne i en anden åre. Som regel anvendes endemufferne dog til at forstærke enderne af en enkelt åre.FIG. 1 shows an already known end sleeve also used on the motor vehicle scope, dg which can be pimped onto the cables in a cable bundle by means of a crimp joint sleeve to contact the ends of one vein with the ends of another vein. As a rule, however, the end sleeves are used to reinforce the ends of a single vein.

I fig. 2 vises en skematisk fremstilling af et elektrisk system l i et motorkøretøj med elektromske og eJektrømekaniske komponenter^ Den form for elektromekaniske komponenter, søm underenhederne 15, 16 og 17 er, kan før eksempei i en enhed til efterbehandling af udstødningsgas være en pumpe til uréaopløsnmg, en ddseringsventil eller et mellemlager. Der er kort sagt tale om separate komponenter 12, 13, 14. I et bremsesystem ville sådanne systemer være bremseskiver eller bremsebakker eller bremseforstærkere. ynderenhederne 15, 16 og 17 er via forblndeiseskabler 20, 21, 22 elektrisk forbundet med en styreen-héd 10, der kan være en central styréenhed i motorkøretøjet eller en special ud viklet styringselektronik. Som regel vil underenhederne 15, 16, 17 befinde sig sammenhængende og ved siden af hinanden, for søm samlet blok at udgøre den pågældende enhed i motorkøretøjet, som for eksempel en enhed til efterbehandiing af udstødningsgas, i et væskéområdé li, hvorfra kablerne 20/ 21, 22 kan føre videre i forskellige retninger som separate årer eller som kabelbundt med mange enkelte årer. Kablerne 20, 21, 22 er afbrudt mekanisk fra beskyttelserne mød krybestrøm i kabler 50, 51, 52, 53, 54, 55, de danner dog en elektrisk forbindelse, via hvilken der både kan overføres styrestrøm og styresignaler, digitalt og analogt, med så ringe interferens som muligt og derfor stort set udæmpet eller helt udæmpet. Beskyttelserne mod kry- fesstrøm i kabler inddeler motorkøretøjet i en væskeførende det med elektriske enheder og et væskefrit, rent elektriskeller eiektroniskdrevet andet område. I et system eller motorkøretøj kan dér også befinde sig en kombination af forskellige beskyttelser mod krybestrøm i kabler 50, 51, 52, 53, 54> 55 ifølge opfindelsen.In FIG. 2 is a schematic representation of an electrical system in a motor vehicle with electric and electromechanical components; dosing valve or intermediate storage. In short, these are separate components 12, 13, 14. In a braking system, such systems would be brake discs or brake trays or brake boosters. the inner units 15, 16 and 17 are electrically connected via blending cables 20, 21, 22 to a control unit 10, which may be a central control unit in the motor vehicle or a specially developed control electronics. As a rule, sub-assemblies 15, 16, 17 will be contiguous and adjacent to each other, for seam assembled block, to constitute the unit in question in the motor vehicle, such as an exhaust gas after-treatment unit, in a fluid area 1 1, from which cables 20/21 , 22 may proceed in different directions as separate veins or as cable bundles with many single veins. The cables 20, 21, 22 are mechanically disconnected from the protectors meet creep current in cables 50, 51, 52, 53, 54, 55, however, they form an electrical connection through which both control current and control signals can be transmitted digitally and analogously, as little interference as possible and therefore largely attenuated or completely attenuated. The protection against creeping current in cables divides the motor vehicle into a fluid carrying it with electrical units and a liquid-free, clean electric or electronically driven other area. In a system or motor vehicle there may also be a combination of various creep current protections in cables 50, 51, 52, 53, 54> 55 according to the invention.

I fig. 3 vises et første udførelseseksempel pi en beskyttelse mod krybestrøm i kabler 50 med et elastisk lederspærreeiement 65, som fortrinsvist er fremstillet af ethylen-propyfen-dien-gummi (EPDM) eller af hy-dreret oitrifguromi (H-NBR). Lederspærreelementet65 ligger fortrinsvist inden for muffen, der er udformet som kontaktomsiutning 60 og lige langt væk fra tilførselsibningen 61 og aflederåbningen 62, således at der dannes en identisk indstiksdybde for en leder 23 eller enkelt Irs 24, der også kan være beklædt (se fig. 4). Lederspærreelementet 65 opdeler kontaktomslutmngens indvendige rum i et rum der optager tilførslen 63, og et rum der optager aflederen 64, Rummet der Optager tilførslen 63 og rummet der optager aflederen 64 udmunder henholdsvis i tilførselsåbningen 61 Og afiedefåbningeh 62. f4idterømrådet i kontaktom-slutningen 60 er det område hvor kontakten afbrydes Si I fig, 4, 5 og 6 er dele der ligner hinanden, forsynet med samme referencetegn sofri I fig. 3, også selvom de fremstår med: ringe ændringer.In FIG. 3, a first exemplary embodiment of a creep flow protection is shown in cables 50 with an elastic conductor barrier element 65 preferably made of ethylene-propylene-diene rubber (EPDM) or of hydrated oitrifrhuromy (H-NBR). The conductor locking element 65 is preferably within the sleeve, which is configured as contact wrapping 60 and equally far away from the supply sieve 61 and the deflector opening 62, so as to form an identical insertion depth for a conductor 23 or single Irs 24 which may also be lined (see Fig. 4 ). The conductor locking element 65 divides the inner space of the contact envelope into a space which receives the supply 63, and a space which occupies the conductor 64, the space which receives the supply 63 and the space which occupies the conductor 64, respectively, in the supply opening 61 and the end opening 60 in the contact space 60. area where the switch is disconnected Si In Figs. 4, 5 and 6, similar parts are provided with the same reference character sofri. 3, even if they appear: minor changes.
