Abstract

The invention is a connector for high currents. It is distinguished in that it comprises a cylindrical contact piece (1) and an outer contact piece (5) encompassing such. The outer contact piece can be axially displaced to and from the contact position by means of a manoeuvring control, and upon contact is pressed against the cylindrical contact piece (1) with the help of the outer contact piece's encompassing conical sleeve (6).<IMAGE>

Description

15 20 25 50 446 573 t 2 Uppfinningen är närmare exemplifierad i bifogade figurer, av vilka fig 1 visar en sidovy av ett kopplingsdon enligt uppfirmingen, och fig 2 visar en tvärsektion längs linje A-A i fig 1. The invention is further exemplified in the accompanying figures, of which Fig. 1 shows a side view of a connector according to the invention, and Fig. 2 shows a cross section along line A-A in Fig. 1.

Kontaktdonet enligtdfigzzrerrza består av en rörlig oylindrisk kontakt 1, vilken består av ett kopparrör, som är tillslutet i kontaktänden och vattenlwlt genom att vatten tillföras genom ett inre rör 2, och strömmar tillbaka i utrymmet 5 mellan tillförselröret 2 och kontaktrörets 1 insida, lämpligen i en ring-formad kanal i den rörliga kontaktdelen. Den rörliga nylinarinka kontakten sken röran från ungefär det pnnkc-nznenkaae ligen till höger i figuren i pilens B riktning till det inritade läget i fig 1.The connector according to the figure consists of a movable non-cylindrical contact 1, which consists of a copper pipe, which is closed at the contact end and watered by water being supplied through an inner pipe 2, and flows back into the space 5 between the supply pipe 2 and the inside of the contact pipe 1, preferably in a ring-shaped channel in the movable contact part. The movable nylinarinka contact shines the mess from approximately the pnnkc-nznenkaae lig to the right in the figure in the direction of the arrow B to the plotted position in Fig. 1.

Cylinderkontakten 1 är anordnad att fasthållas av en chuckancrdning 4, som lqvles genom kontakt med cylinderkontakten 1. Chuckanordningen består ianpiigen av tre knnnnmbiem 5 (se även rig 2), nen givetvis ai- annan antal backar också möjligt. Kontaktbackarna 5 pressas med stor kraft mot cylinderkontalcten då. de omslutes av en presskona 6, som pressas axiellt mot kontaktbackarna 5 av fjädern 7. Fjädern kan, som visas, vara uppbyggd av fjäderbrickor eller bestå. av en spiralfjäder. Det är också tänkbart att ersätta eller komplettera fjädern med presskraft från en Ixydraullcolv (ej visad).The cylinder contact 1 is arranged to be held by a chuck device 4, which is maintained by contact with the cylinder contact 1. The chuck device consists of three gears 5 (see also row 2), of course a different number of jaws is also possible. The contact jaws 5 are pressed with great force against the cylinder contact then. they are enclosed by a press cone 6, which is pressed axially against the contact jaws 5 of the spring 7. The spring can, as shown, be built up of spring washers or consist. of a coil spring. It is also conceivable to replace or supplement the spring with compressive force from an Ixydraull piston (not shown).

Presskonan 6 är fast monterad och är via kolvstången 8 kopplad till en hydraulcylinder 9. Dennas yttermantel är via stänger 10 och 11 samt ett nn 12 förbunden nen knntnxebnnknm 5. när nyarnnlnylinaem manövreras ligger således kolven stilla medan yttermanteln rör sig, varvid kontakt- backarna pressas axiellt ut ur presskonan 6. Fjädrar (ej visade) mellan backarna. i chuckanordningen gör, att 'dessa föres isär så. att chuckanord- ningen gapar och oylinderkontakten blir fri och kan dras ut.The press cone 6 is fixedly mounted and is connected via the piston rod 8 to a hydraulic cylinder 9. Its outer jacket is connected via rods 10 and 11 and a nn 12 nne knntnxebnnknm 5. when the new line is operated the piston thus lies still while the outer jacket moves, the contact jaws axially out of the press cone 6. Springs (not shown) between the jaws. in the chuck device causes these to be disassembled so. that the chuck device gapes and the cylinder contact becomes free and can be pulled out.

Då kontaktdonet åter skall slutas förs cylinderkontakten 1 tillbaka in i chuckanordiiingen 4. Eftersom ohuckanordningen gapar kan detta göras lätt och utan större krav på. precision. Sedan manövreras hydraulcylindern, var- vid backarna dras tillbaka. axiellt in i presskonan 6 och med stor kraft mot cylinderkontakten 1. Dackarna 5 rör sig således i oylinderkontaktens 1 axiella riktningii sättningsögonblioket. Denna rörelse är viktig och bidrar till god kontaktfimktion, eftersom oxidskikt på kontaktytorna därvid rivs upp.When the connector is to be closed again, the cylinder contact 1 is moved back into the chuck device 4. Since the hook device gaps, this can be done easily and without major requirements. precision. The hydraulic cylinder is then operated, whereby the jaws are retracted. axially into the press cone 6 and with great force against the cylinder contact 1. The dowels 5 thus move in the axial direction of the cylinder contact 1 at the moment of insertion. This movement is important and contributes to good contact function, as oxide layers on the contact surfaces are thereby torn up.

5 446 573 I fig 1 visas, streck-prickat, kontaktbackamas 5 och cylinderkontaktens 1 läge då. kontaktdonet är öppnat. Strömmen överförs till kontaktbackaxna via flexibla anslutningar 13, som i sin tur är anslutna till strömledare 14. 15 och 16 visar alternativa lägen för de flexibla anslutningarna och strömledarxla. För att säkerställa att kontaktytorrza mellan presskona 6, kontaktbackar 5 och cylinderkontakt 1 alltid är rena finns anslutning 17 för spolluft i presskonan. Strömledarxms dragning och kontaktbacloarnas och de flexibla anslutningar- nas lägen framgår klarare i fig 2, där placeringen runt den cylindriska kontakten 1 klart visas. Anordningen enligt ovan kan varieras på. mång-ahanda sätt inom ramen för nedanstående patentlcrav. PATENTKRAVFig. 1 shows, in dashed lines, the position of the contact jaws 5 and the cylinder contact 1 then. the connector is open. The current is transmitted to the contact jaws via flexible connections 13, which in turn are connected to current conductors 14. 15 and 16 show alternative positions for the flexible connections and current conductor shaft. To ensure that the contact dry between the press cone 6, contact jaws 5 and cylinder contact 1 is always clean, there is a connection 17 for purge air in the press cone. The routing of the current conductor axis and the positions of the contact bacloars and the flexible connections are clearer in Fig. 2, where the location around the cylindrical contact 1 is clearly shown. The device as above can be varied. in many ways within the scope of the following patent claims. PATENT REQUIREMENTS 1.
