Description
5352 åâš SAM MAN FATTN I NG Ett syfte med den föreliggande uppfinningen är att tillhandahålla ett förbättrat jordningsdon till ett fordon, särskilt då till ett tungt fordon som en lastbil eller en buss. 5352 åâš SUMMARY An object of the present invention is to provide an improved earthing device for a vehicle, especially for a heavy vehicle such as a truck or a bus.
Detta och andra syften uppnås med detjordningsdon som anges i bifogade krav.This and other objects are achieved with the grounding device specified in the appended claims.
Följaktligen tillhandahålls ett jordningsdon som tillhandahåller en jordanslutningskontakt i ett fordon. Jordningsdonet är utformat som en elektriskt ledande hylsa med en i allt väsentligt konisk form samt en insats som har en i allt väsentligt konisk form och som är konstruerad i ett material som är hårdare än hylsan.Accordingly, a grounding device is provided which provides a ground connection connector in a vehicle. The grounding device is designed as an electrically conductive sleeve with a substantially conical shape and an insert which has a substantially conical shape and which is constructed in a material which is harder than the sleeve.
Uppfinningen avser även ett fordon som innefattar ett jordningsdon i enlighet med ovanstående beskrivning.The invention also relates to a vehicle which comprises a grounding device in accordance with the above description.
KORT BESKRIVNING AV RITNINGARNA Den föreliggande uppfinningen beskrivs nu mer detaljerat med hjälp av icke- begränsande exempel och med hänvisning till bifogade ritningar, där: - Fig. 1a visar en hylsa tillhörande ett jordningsdon, - Fig. 1b visar en insats tillhörande ett jordningsdon, - Fig. 1c visar en hylsa som samverkar med en insats som tillsammans bildar ett jordningsdon, och - Fig. 2 visar en kombinerad genomskärnings- och sidovy av ett jordningsdon. 10 20 25 EEQ 425 DETALJERAD BESKRIVNING l Fig. 1a visas en hylsa 1 tillhörande ett jordningsdon 3. Hylsan 1 innefattar kragar 1a sammanbundna med en flänsdel 1b. Hylsan 1 tillverkas företrädesvis i ett ledande material med relativt mjuka egenskaper vilket möjliggör att hylsan kan expandera i en tvärriktning. Hylsan 1 kan till exempel vara tillverkad i koppar, främst förtennad koppar.BRIEF DESCRIPTION OF THE DRAWINGS The present invention is now described in more detail by means of non-limiting examples and with reference to the accompanying drawings, in which: - Fig. 1a shows a sleeve belonging to a grounding device, - Fig. 1b shows an insert belonging to a grounding device, - Fig. 1c shows a sleeve which cooperates with an insert which together form a grounding device, and Fig. 2 shows a combined cross-sectional and side view of a grounding device. EEQ 425 DETAILED DESCRIPTION Fig. 1a shows a sleeve 1 belonging to a grounding device 3. The sleeve 1 comprises collars 1a connected to an end part 1b. The sleeve 1 is preferably made of a conductive material with relatively soft properties, which enables the sleeve to expand in a transverse direction. The sleeve 1 can, for example, be made of copper, mainly tinned copper.
Hylsan har en i allt väsentligt konisk form för att passa i ett hål anbringat i fordonsramen. Kragama 1a ger den konlska formen med vilken hylsan 1 kan föras in i ett hål som har konisk form vilket är vanligt förekommande när ett hål har stansats utan efterföljande putsning. Förutom att sammanbinda kragarna 1a utgör flänsdelen en elektrisk anslutningskontakt till vilken jordning kan ske. l Fig. 1b visas en insats 2 som ska tryckas eller på annat sätt föras in i hylsan 1. insatsen 2 har en i allt väsentligt konisk form för att passa både hylsans 1 form och ett hål ifordonsramen. insatsen 2 är företrädesvis tillverkad i ett material som är hårdare än hylsan 1 och kan vara tillverkad i stål. lnsatsens utsida har en struktur som är avpassad för att låsa fast i hylsan. Utsidan kan till exempel vara skrovlig eller gängad. lnsatsens insida är utformad för att passa ett verktyg som är avpassat för att föra in insatsen i hylsan. Till exempel kan insidan ha jämna väggar eller gängade väggar beroende vilket verktyg som används för insättning av insatsen 2. Ett verktyg för montering av blindnitar är särskilt lämpat för insättning av insatsen 2.The sleeve has a substantially conical shape to fit in a hole provided in the vehicle frame. The collars 1a give the conical shape with which the sleeve 1 can be inserted into a hole which has a conical shape which is common when a hole has been punched without subsequent polishing. In addition to connecting the collars 1a, the end part constitutes an electrical connection contact to which earthing can take place. Fig. 1b shows an insert 2 to be pressed or otherwise inserted into the sleeve 1. the insert 2 has a substantially conical shape to fit both the shape of the sleeve 1 and a hole in the vehicle frame. the insert 2 is preferably made of a material which is harder than the sleeve 1 and may be made of steel. The outside of the insert has a structure that is adapted to lock in the sleeve. The outside can, for example, be rough or threaded. The inside of the insert is designed to fit a tool that is adapted to insert the insert into the sleeve. For example, the inside may have smooth walls or threaded walls depending on which tool is used for inserting the insert 2. A tool for mounting blind rivets is particularly suitable for inserting the insert 2.
I Fig. 1c visas jordningsdonet 3 vid montering där insatsen 2 förs in i hylsan 1.Fig. 1c shows the earthing device 3 during assembly where the insert 2 is inserted into the sleeve 1.
I Fig. 2 visas jordningsdonet 3 monterat i ett hål 5 i fordonsramen 4. Den övre delen av Fig. 2 är en genomskärningsvy som visar hylsans 1 och lnsatsens 2 position när de monteras med ett monteringsverktyg i hålet 5. 532 425 _4_ lnsatsens 2 insida 6 kan vara slät eller gängad. Den nedre delen av Fig. 2 är en sidovy av den andra hälften av jordningsdonet monterat i hålet 5. Hålet 5 kan i ett utförande vara koniskt. En konisk form på hålet kan till exempel vara ett resultat av att hålet stansats i ramen 4.Fig. 2 shows the earthing device 3 mounted in a hole 5 in the vehicle frame 4. The upper part of Fig. 2 is a sectional view showing the position of the sleeve 1 and the insert 2 when they are mounted with a mounting tool in the hole 5. 532 425 _4_ the inside of the insert 2 6 can be smooth or threaded. The lower part of Fig. 2 is a side view of the other half of the earthing device mounted in the hole 5. The hole 5 can in one embodiment be conical. A conical shape on the hole may, for example, be a result of the hole being punched in the frame 4.
Användning av jordningsdon i enlighet med beskrivningen häri kommer att leda till lägre komponentkostnader i jämförelse med befintliga metoder som tillhandahållerjordningsdon. Dessutom kommer kontaktytan att bli större vilket i sin tur förbättrar jordningsdonets elektriska egenskaper.The use of grounding devices as described herein will result in lower component costs compared to existing methods of providing grounding devices. In addition, the contact surface will be larger, which in turn improves the electrical properties of the earthing device.
Vidare kan jordningsdonet förmonteras vid montering av fordonsramen och därigenom minska korrosionsrtsken, eftersom monteringen kan äga rum innan màlningsarbete utförs.Furthermore, the earthing device can be pre-assembled during assembly of the vehicle frame and thereby reduce the corrosion risk, since the assembly can take place before painting work is performed.
Monteringstiden är mycket kort på grund av det ringa antalet komponenter och behovet av enbart ett verktyg vid endast ett tillfälle för varje jord ningsdon som anbringas i ramen. Jordningsdonet kan användas i ett stansat hål med konisk form vilket därigenom eliminerar behovet av putsning, urborming eller liknande åtgärd. Ett standardverktyg kan användas vid montering av jordningsdonet.Assembly time is very short due to the small number of components and the need for only one tool at a time for each grounding device mounted in the frame. The earthing device can be used in a punched hole with a conical shape, which thereby eliminates the need for trimming, drilling or similar action. A standard tool can be used when mounting the earthing device.
