Elektrisk kontaktforbindning och satt for dess framstallning. Electrical contact connection and set for its manufacture.

Foreliggande uppf inning hanfor sig till elektriska kontaktforbindningar, som me- deist en elektrisk ledning skola forbinda ett par foremal. Dylika kontaktforbindningar anvaniclas exempelvis for elektriskt forbindande av ett par ralsandar med varandra, varvid kontaktforbindningen bestar av en elektrisk ledning och tvenne pa vardera fin- den av ledningen fastsatta kontaktskor, som pa ett eller annat satt aro fasta vid ralsandarna t. ex. genom mekanisk hopfogning, lodning eller manuell svetsning. Vid lodning far man den fordelen, att grundmaterialet, ralen, aldrig upphettas till smaltning eller sadan temperatur att nagon hardning av vederborande del av grundmaterialet kan intraffa, men samtidigt stalles stora ,ansprak pa sjalva utforandet av Nidningen for att denna skall fa tillracklig hallbarhet. Uppfinningen avser sarskilt att tillgodose sistnamnda fordran och samtidigt mojliggOra ,ett snabbt och behhndigt fastsattande av kontaktforbindningen. The present invention relates to electrical contact connections, which by means of an electrical line are to connect a pair of objects. Such contact connections are used, for example, for electrically connecting a pair of ral sands to each other, the contact connection consisting of an electrical wire and two contact shoes attached to each end of the wire, which on one side or the other are attached to the ralsandar, e.g. by mechanical joining, soldering or manual welding. When soldering, one has the advantage that the base material, the rale, is never heated to melting or such a temperature that any hardening of the adjacent part of the base material can occur, but at the same time is made large, claiming the very design of Nidningen for it to have sufficient durability. In particular, the invention is intended to satisfy the latter requirement and at the same time enable, a quick and convenient fastening of the contact connection.

En. elektrisk kontaktforbindning, bestaende av en ledning saint pa dennas bada andar anbragta kontaktskor, utmfirkes enligt uppfinningen darav, att vardera kontaktskons for anliggning mot en ral eller ett formal avsedda del ãr forsedd med hdl och att en metallpinne fir anbragt i halet samt genom delvis smaltning och .darefter foljande stelnande bildar en fast forbindning mellan rdlen eller fOremalet och respektive kontaktsko. Enligt uppfinningen aro de pa kant satt av rorstycken bestaende kontaktskorna, som till hela sin langd omsluta den av ett flertal tradar bildade ledningen, jamte ledningstradarna tillplattade vid yttre anden och hava halet gaencle tvars igenom den tillplattade delen. Uppfinningen .avser aven sattet att framstalla en dylik kontaktforbindning, vilket satt narmare skall forklaras i f8ljande beskrivning. One. electrical contact connection, consisting of a wire saint on the two spirits placed contact shoes, is distinguished according to the invention from then the following solidification forms a solid connection between the groove or the object and the respective contact shoe. According to the invention, the contact shoes consisted on the edge of pipe pieces, which for their entire length enclose the wire formed by a plurality of wires, as well as the wire wires flattened at the outer spirit and having the tail gaencle across the flattened part. The invention also relates to the method of producing such a contact connection, which method will be explained in more detail in the following description.

Ett par sasom exempel visade utfOranden enligt uppfinningen askadliggoras pt bifogade ritning. Fig. 1 och 2 visa tvenne i mot varandra vinkelrata riktningar sedda vyer av en kontaktforbindning fore fastsfittningen. Fig. 3 visar en sidovy av en fastsatt kontaktforbindning. Fig. 4 visar en del av en modifierad kontaktfOrbindning. Fig. och 6 visa langdsektioner genom pa olika sfitt utformade delar for kontaktforbindningen. A couple of such examples show the embodiments according to the invention as shown in the accompanying drawing. Figs. 1 and 2 show two views of the contact connection before the fitting seen in perpendicular directions. Fig. 3 shows a side view of a fixed contact connection. Fig. 4 shows a part of a modified contact connection. Figs. And 6 show longitudinal sections through parts designed for different contact connections.

Enligt det i fig. 1-3 visade utfOrandet ar vardera kontaktskon, utford av ett rorstycke som till hela sin langd patratts resp. dude pa en elektrisk ledning 2, bildad av ett flertal tradar av metall, exempelvis koppartradar. Kontaktskons yttre ande och de darigenonu gaende ledningstradarna aro hoppressade, sa att en tillplattad del 3 erhalles. Tvars igenom denna del 3 ar upptaget ett hal 4, som saledes gar igenom saval de tillplattade rorvaggarna som de vid platsen for halet sig strackantle ledningstradarna. According to the embodiment shown in Figs. 1-3, each contact shoe is challenged by a piece of pipe which, for its entire length, is patrated resp. dude on an electrical wire 2, formed by a plurality of wires of metal, for example copper wires. The external spirit of the contact and the conducting wires therein are compressed, so that a flattened part 3 is obtained. Throughout this part 3 a hall 4 is occupied, which thus passes through both the flattened rudder walls and the ones at the place of the haul.

I och for fastsattning av kontaktforbindningen vid ett par riarbelagna ralsandar i ett spar for att bilda en elektrisk ledning mellan dessa anbringas den enn kontaktskons tillplattade del 3 emot ralsanden, sasom fig. 3 visar, och darefter infores en pilule 5 i halet 4 och emot ralsanden saint bringas att i sadan grad smalta, genom att elektrisk strom ledes genom pinnen till ralsfinden, att small material fran pinnen efter stelnandet bildar en fast forbindning mellan ralsanden och kontaktskon. Darefter fastsattes den andra kontaktskon vid sin ralsande ph samma shtt och en hallbar elektrisk forbindelse mellan ralsandarna liar uppnalts. In order to attach the contact connection to a pair of rubber-coated rale sands in a groove to form an electrical wire between them, the flattened part 3 of the contact shoe is applied against the ralsand, as Fig. 3 shows, and then a pellet 5 is inserted into the tail 4 and against the ralsand saint is caused to melt to such an extent, by conducting electric current through the pin to the ralsfind, that small material from the pin after solidification forms a solid connection between the ralsand and the contact shoe. Then the second contact shoe was attached to its ralsande ph the same shtt and a durable electrical connection between the ralsandar liar was achieved.

Vid grovre ledningar med storre kontaktskor kunna tit hal, enligt fig. 4, eller flera forefinnas for anbringande av flistpinnar. In the case of coarser wires with larger contact shoes, ten or more slips, according to Fig. 4, can be present for fitting chipping pins.

Hela fastpinnen kan besta av samma material som blott debris nedsmaltes for att erforderligt small material skall erhallas, men I sa fall fordras speciella forsiktighetsatgarder. Det synes darfor vara lampligare att utf8ra fastpinnen air tvenne material med olika smaltpunkt. The entire stick can consist of the same material as only debris was melted down in order to obtain the required small material, but in that case special precautionary measures are required. It therefore seems more appropriate to make the fixed pin air two materials with different melting points.

Enligt fig. bestar pinnen av en del 6 av stal och en del 7 av svetsbrons, paljelod, sil- verlod eller dylikt relativt latt smaltbart ma- terial eller lodmetall. I delens 7 yttre ande fir en halighet, fylld med flussmedel 8 och till- sluten med ett lock 9, som bestar a-v samma material som delen 7. Vid fastIodning fasthalles delen 6 av en magnet och strom framslappes genom fastpinnen, sa att en ljusbage 2— — bildas mellan locket 9 och ralsanden, Hussraedlet flyter ut och delen 7 smatter saint rinner icke blott in mellan den tillplattade delen 3 och ralen utan aven genom halet 4 in mellan ledningstradarna narmast halet 4 och bildar vid stelnandet en fast forbindning ralen, kantaktskons undersida, pinnen och mellan ledningstradarna inbardes samt mellan dessa och den tillplattade delens innersida. Pa en och samma gang erhalles saledes bade fastsattning av skon vid ralen och forbattrad forening av ledningstradarna med resp. sko. According to Figs., The pin consists of a part 6 of steel and a part 7 of welding bronze, bead solder, silver solder or the like relatively easily fusible material or solder metal. In the outer spirit of the part 7 there is a cavity, filled with flux 8 and closed with a lid 9, which consists of the same material as the part 7. When soldering, the part 6 is held by a magnet and current is passed through the fixed pin, so that a candle bag 2 - - is formed between the lid 9 and the ralsand, the housing rudder flows out and the part 7 smatter saint not only flows in between the flattened part 3 and the ral but also through the tail 4 in between the conductor lines closest to the rag 4 and forms a solid connection ral, , the pin and between the wire lines were brought in and between these and the inside of the flattened part. Thus, at the same time, both the attachment of the shoe to the rail and the improved union of the wires with resp. shoe.

Principen i uppfinningen andras givetvis icke, om den i fig. 1 och fig. 2 visade kontaktfarbindningen är utford pa Want satt att de i den elektriska ledningen 2 ingdende tradarna endast skjuta ett stycke in uti det till kabelsko utformade rorstycket 1 och fore fastsattandet vid ralen genom en sarskild lodningsprocedur fastlotts till rOret 1. Detta tillvagagangsatt kan vara lampligt att anvanda, vid s grova dimensioner pa kabeln 2, att det kan tankas att tjockleken pa den tillplatlade delen 3 skulle bli for stor, ern kabeln 2 ginge fram farbi halet 4, och svarigheter pa grund av den stora godstjockleken skulle uppsta vid fastsattandet av kontaktfOrbindningen vid ralen. The principle of the invention is of course not changed, if the contact connection shown in Fig. 1 and Fig. 2 is challenged in the sense that the wires included in the electrical line 2 push only a piece into the pipe piece 1 formed for cable lugs and fasten to the rail. by a special soldering procedure attached to the pipe 1. This approach can be convenient to use, with such large dimensions on the cable 2, that it is conceivable that the thickness of the flattened part 3 would become too large before the cable 2 advanced past the tail 4, and responsibilities due to the large thickness of the material would arise when attaching the contact connection to the rail.

I stallet for magnetiskt medal far fasthallning av fastpinnen under fastsattningen kan en mekanisk gripanordning anviindas, vid vilket senare fall fastpinnen Iampligen utfOres sasom fig. 6 visar. Harvid ar den av material med hogre smaltpunkt utforda delen relativt lang, sh att dess forlangningsdel 10 kan insattas i en hylsa, som tjanar icke blott som hallare ,utan aven som stramtilledare och foretradesvis ingar i en s. k. svetspistol for fastsvetsning av bultar. Mellan forlangningsdelen 10 och den del 11, som skall utfylla ett hal 4 i kontaktskon ar ett runtomgaende spar 12. Hela delen 10, 11 är av ett relativt skort material, t. ex. en sprOd massing. Nar darfor denna pinne fastlotts, behover man blott sla till hell latt pa forlangningsdelen 10 for att brott skall uppsta vid sparet 12 och den i kontaktskon fastsatta pinnen komma att na blott obetydligt utanfor kontaktskon. Instead of a magnetic medal holding the fixing pin during the fastening, a mechanical gripping device can be used, in which later case the fixing pin is preferably made as Fig. 6 shows. In this case, the part of material with a higher melting point is relatively long, so that its extension part 10 can be inserted into a sleeve, which serves not only as a holder, but also as a tension conductor and preferably in a so-called welding gun for welding bolts. Between the extension part 10 and the part 11, which is to fill a hall 4 in the contact shoe, there is a circumferential groove 12. The whole part 10, 11 is of a relatively short material, e.g. a sprOd massing. Therefore, when this pin is secured, all that is needed is to lightly tap the extension member 10 so that breakage will occur at the slot 12 and the pin attached to the contact shoe will reach only insignificantly outside the contact shoe.

Andra satt far utforandet av pinnen kan ocksa tankas. SA t. ex. kan forlangningsdelen 10 pa den i fig. 6 visade pinnen ersattas av ett i delen 11 i axial riktning ga.ende hal, som tjanstgOr som hallare och stromtilledare pa samma satt som fallet Or med en enpolig stickkontakt. SvetspistoIens som hallare och stramtilledare tjanstgorande hylsa maste i sâ fall ersattas av en cylindrisk tapp, som genom uppslitsade spar bibringas en titan fjadring i radiell riktning. Others sat father the design of the stick can also be refueled. SA e.g. For example, the extension part 10 on the pin shown in Fig. 6 can be replaced by a hall running in the axial direction in the part 11, which serves as a holder and current conductor in the same way as the case Or with a single-pole plug. The welding pistol, which serves as a holder and a tension conductor, must in that case be replaced by a cylindrical pin, which is provided with a titanium spring in the radial direction through slotted grooves.

Uppfinningen skall icke anses begransad till blott de beskrivna och pa ritningen visa-de utforingsformerna, enar dessa kunna varieras inom uppfinningens ram. Sarskilt fast pinnen kan Tara utford pa olika satt. Kontaktskons inre ande kan vara forsedd med en runtomgaende inpressning for att fastare OMsluta ledningen. The invention is not to be construed as limited to only the embodiments described and shown in the drawing, these may be varied within the scope of the invention. Especially the stick can challenge Tara in different ways. The inner spirit of the contact cone may be provided with a circumferential indentation to more firmly enclose the wire.
