Description

459 705 anpassa skärkanten resp -kanterna till rundningen hos innerväggen på backen resp backarna. 459 705 align the cutting edge or edges with the rounding of the inner wall the hill or the slopes.

En speciell utföringsform består därvid i att dela upp skär- kanterna i delelement och anordna dem i de avrundade partierna i backarnas innerväggar sida vid sida med inbördes vinkel i skärplanet, så att de kan utöva sin skärverkan över-backarnas hela rundade parti.A special embodiment then consists in dividing the cutting the edges of sub-elements and arrange them in the rounded portions in the inner walls of the slopes side by side with a mutual angle in the cutting plane, so that they can exert their cutting action over the entire rounded portion of the slopes.

Detta uppnås även med skärkanter, som är utförda som ringpartier. Hur som helst medför detta ifråga om skärningen, att skärkanten förlängs relativt icke uppdelade, raka skärkanter, och förstoring av gripzonen_ genom att skärkanternas delelement är anordnade i vinkel. Gripzonen fördubblas givetvis om man istället för bara en skärkant i den ena backen samtidigt anordnar skärkanter i båda backarna enligt ett ut- förande av uppfinningen, varvid backarnas skärkanter då består av de beskrivna och på likadant sätt anordnade delelementen. Man uppnår då .att eggarna på skärkanterna resp på deras delelement är verksamma runt om inuti backarna.This is also achieved with cutting edges, which are designed as ring portions. How in any case, in the case of cutting, this means that the cutting edge is extended relatively undivided, straight cutting edges, and enlargement of the grip zone_ in that the sub-elements of the cutting edges are arranged at an angle. Grip zones doubles, of course, if instead of just a cutting edge in one the slope simultaneously arranges cutting edges in both slopes according to a carrying out the invention, the cutting edges of the jaws then consisting of those described and similarly arranged sub-elements. You achieve then .that the edges on the cutting edges or on their sub-elements are active around about inside the slopes.

Lämpligen ges skärkanterna en sådan optimal utsträckning i om- kretsriktningen, att den vridning av avisolerdonet som krävs för att skära av isoleringen begränsas till 90° i motsats till de 1800 eller mer som krävs vid konventionella verktyg.Suitably the cutting edges are given such an optimal extent in the the direction of rotation, that the rotation of the stripper required to cutting of the insulation is limited to 90 ° as opposed to the 1800 or more required by conventional tools.

Vidare är det lämpligt att förse backarna med en avisoleringsan- ordning bakom skärkanterna. Avisoleringsanordningen kan bestå av två knivblad, som är fästa på var sin back på de kortsidor som är vända bort från skärkanterna. När backarna rör sig mot varandra går knivbladen skärartat över och under varandra och skär på detta sätt in i eller av isoleringen, så att denna kan avlägsnas utan ansträngning. Alternativt kan backarna bakom skärkanterna på motstàende ställen på de yttre längs- kanterna förses med flera bredvid varandra liggande skarpkantade skåror som avisoleringseggar.Furthermore, it is advisable to provide the slopes with a stripping device. order behind the cutting edges. The stripping device can consist of two knife blades, which are attached to each back on the short sides that are turned away from the cutting edges. When the slopes move towards each other, the knife blades move cut above and below each other and cut into or off in this way the insulation, so that it can be removed without effort. Alternatively the slopes behind the cutting edges at opposite points on the outer longitudinal the edges are provided with several adjacent sharp-edged notches as stripping eggs.

De beskrivna utföringsformerna av skalverktyget enligt uppfin- ningen har den fördelen, att de möjliggör att bàde avlägsna den yttre isoleringen på en kabel och avisolera de enskilda innerledarna. Mon-_ tören slipper alltsa ha tvâ olika handverktyg för att avisolera en kabel och dess innerledare.The described embodiments of the scaling tool according to the invention has the advantage that they make it possible to remove both the exterior the insulation on a cable and strip the individual inner conductors. Mon-_ the torso does not have to have two different hand tools to strip one cable and its inner conductor.

I det följande beskrivs som icke bindande exempel några utförings- former av uppfinningen med hänvisning till ritningen, där fig 1 visar backarna i planvy i uppfällt tillstànd; fig 2 tillhörande ändvy; fig 3 en modifierad utföringsform enligt fig 1; fig 4 de hopslagna backarna med iliggande kabel i planvy; fig 5 en vy av ett avisoleringsdon med speciell utformning av skärkanterna med utfällda backar; fig 6 till- 459 7057 hörande planvy sedd i riktning mot den ände, där skärkanterna är anord- nade; fig 7 sammalunda i planvy med backarna nästan hopslagna och med iliggande kabel; fig 8 sammalunda i planvy med öppna backar med ring- partiformiga skärkanter; fig 9 en vy av ett med sina backar utfällda skalverktyg med avisoleringsanordning; fig 10 tillhörande planvy med en utsikt mot knivbladen vid utfällda.backar; och fig 11 tillhörande planvy i det läge da backarna är hopslagna och knivblande griper skär- artat över och under varandra. ' Backarna 1, 2, som på känt sätt är försedda med skärkanter 3, 4 i ena änden, har i genomskärning cylindersegmentform och är inbördes svängbart förbundna längs intilliggande lângsidor med hjälp av gäng- järn 5, 6, så att de kan fällas samman till en ihålig kropp. Det halrum som då bildas tjänar till att ta upp den kabel 7 som ska skalas, jfr fig 4. När kabeln 7 lagts i de från varandra utfällda backarna 1, 2, tränger vid den följande hopfällningen av backarna 1, 2 skärkanterna 3, 4 in i kabelns 7 isolerskal, varvid isolerskalet skärs av runt om genom att backarna 1, 2 vrids och får utföra en lätt brytrörelse i sid- led. Genom att man drar i backarna 1, 2 resp drar ut kabeln 7 ur backar- na 1, 2 skalas sedan det avskurna stycket av isolerskalet av från inner- kabeln. En på den ena backen anordnad klack 8 understödjer därvid handhavandet av verktyget.In the following, as non-binding examples, some embodiments are described. forms of the invention with reference to the drawing, in which Fig. 1 shows the slopes in plan view in the raised condition; Fig. 2 associated end view; fig 3 a modified embodiment according to Fig. 1; Fig. 4 shows the folded slopes with adjacent cable in plan view; Fig. 5 is a view of a stripper with special design of the cutting edges with extended jaws; Fig. 6 to 459 7057 associated plan view seen in the direction of the end, where the cutting edges are arranged nade; Fig. 7 together in plan view with the slopes almost folded and with adjacent cable; Fig. 8 together in plan view with open jaws with ring biased cutting edges; Fig. 9 is a view of one with its jaws unfolded scale tool with stripping device; Fig. 10 associated plan view with a view of the knife blades at unfolded.backs; and Fig. 11 associated plan view in the position where the slopes are folded and stabbing grips species above and below each other. ' The jaws 1, 2, which in a known manner are provided with cutting edges 3, 4 at one end, has a cross-section cylindrical segment shape and is spaced apart pivotally connected along adjacent longitudinal sides by means of threaded iron 5, 6, so that they can be folded into a hollow body. The hall which is then formed serves to pick up the cable 7 to be scaled, cf. Fig. 4. When the cable 7 is laid in the unfolded jaws 1, 2, penetrates at the following folding of the jaws 1, 2 the cutting edges 3, 4 into the insulating shell of the cable 7, the insulating shell being cut off all around by turning the jaws 1, 2 and having to perform a slight breaking movement in the lateral led. By pulling in jaws 1, 2 or pulling out the cable 7 from the jaws 1, 2 is then peeled off the cut piece of the insulating shell from the inside. cable. A lug 8 arranged on one hill then supports it operation of the tool.

Givetvis kan backarna 1, 2 också förbindas med endast ett gång- järn 9, jfr fig 3, eller vid tvâ gångjärn förses med en gemensam gång-_ järnsaxel 10, jfr fig 1. _ Genom skalverktyget_enligt uppfinningen kan alltså isolerskalen hos en- eller flerledarkablar handhas enklare och med färre hjälpmedel än förut. ' Vid utförandet enligt fig 5-7 är de vid backarnas 1, 2 främre ändar anordnade skärkanterna 3, 4 uppdelade i delelement 11, 12 och 13, 14, som är vinkelställda mot varandra i skärplanet pa sådant sätt, att deras skäreggar sträcker sig helt över backarnas 1, 2 inre runda partier, jfr fig 6. vid slutna backar 1, 2 och ilagd kabel 7, jfr fig 7, bildas pá detta sätt pa backarnas 1, 2 insidor en runtgaende skärkant, som da verktyget resp backarna 1, 2 vrides samtidigt skär in i kabeln 7 i den periferiyta som ligger mittemot skärkanternas 3, 4 delelement 4-14.Of course, the jaws 1, 2 can also be connected to only one iron 9, cf. Fig. 3, or in the case of two hinges is provided with a common hinge. iron shaft 10, cf. fig 1. _ The insulating shell can thus be insulated through the peeling tool according to the invention with single- or multi-conductor cables is handled more easily and with fewer aids than before. ' In the embodiment according to Figs. 5-7, they are in front of the jaws 1, 2 ends arranged cutting edges 3, 4 divided into sub-elements 11, 12 and 13, 14, which are angled to each other in the cutting plane in such a way that their cutting edges extend completely over the inner round of the slopes 1, 2 parties, cf. Fig. 6. at closed jaws 1, 2 and laid cable 7, cf. fig. 7, is formed on this way on the inside of the slopes 1, 2 inside a circumferential cutting edge, as then the tool or jaws 1, 2 are turned at the same time cut into the cable 7 in it peripheral surface opposite the cutting edges 3, 4 sub-elements 4-14.

Därvid skärs kabelisoleringen av helt redan efter att verktyget vridits i i praktiken 90 grader.In this case, the cable insulation is cut off completely already after the tool has been turned in practice 90 degrees.

En ytterligare utföringsform av uppfinningstanken består som visas i fig 8 i att skärkanterna 3, 4 utformas som ringpartier 18, 19, ___., -1 459 705 4 .som motsvarar formen på backarnas 1, 2 insidor. Även härvid bildas en runtgående skärkant, vilken som 'beskrivits endast kräver att verktyget manövreras i i praktiken 90°.A further embodiment of the inventive concept consists as is shown in Fig. 8 in that the cutting edges 3, 4 are formed as ring portions 18, 19, ___., -1 459 705 4 .which corresponds to the shape of the insides of the slopes 1, 2. Here, too, a circumferential cutting edge, which as' described only requires the tool operated in practice at 90 °.

För att underlätta handhavandet av verktyget är backarna 1, 2 försedda med var sin symmetrisk dubbelklack 20, 21 och 15, 16, som vid hopfällda backar 1, 2 bildar kompakta dubbelpucklar, vilka i samverkan med ett i luckan 22 ifört finger, t ex pekfingret, speciellt då den avskurna isoleringen ska dras av, förbättrar handens grepp om verktyget.To facilitate the operation of the tool, the jaws are 1, 2 provided with their respective symmetrical double heels 20, 21 and 15, 16, as at folded slopes 1, 2 form compact double humps, which in cooperation with a finger inserted in the cover 22, for example the index finger, especially when it cut insulation should be pulled off, improves hand grip on the tool.

Som visas i fig 9-11 är backarna 1, 2 på de kortsidor som ligger motsatt skärkanterna 3, 4 försedda med en avisoleringskniv 23. Denna består av knivbladen 27, 28, som är fästa på var sin back 1, 2, närmare bestämt på sådant sätt, att när backarna fälls samman till en hálkropp, rör sig knivldaden 27, 28 mot varandra och griper därvid skärartat framför och bakom varandra. Därvid avskiljs resp avskärs isoleringen pà en mellan knivbladen 27, 28 befintlig kabelledare.As shown in Figs. 9-11, the slopes 1, 2 are on the short sides which lie opposite the cutting edges 3, 4 provided with a stripping knife 23. This consists of the knife blades 27, 28, which are attached to each jaw 1, 2, closer determined in such a way that when the slopes fold into a slippery body, the blade blade 27, 28 moves towards each other and thereby grips in a cutting manner in front and behind each other. The insulation is then separated or cut off on an existing cable conductor between the knife blades 27, 28.

Man kan också istället för de beskrivna knivbladen 27, 28 förse backarna 1, 2 med flera, t ex två bredvid varandra liggande skarp- kantade och spegelartat lika hack 24, 25, 30, 31 som avisoleringsknivar bakom knivarna 3, 4 på motstående ställen på de yttre längskanterna 26, 29.It is also possible to provide instead of the described knife blades 27, 28 the slopes 1, 2 and more, for example two adjacent sharp edged and mirror-like notches 24, 25, 30, 31 as stripping knives behind the knives 3, 4 in opposite places on the outer longitudinal edges 26, 29.

När man fäller saman backarna 1, 2 avskiljer resp avskär häcken 24,25,30,31 isoleringen från en mellan dem belägen kabelledare.When folding down slopes 1, 2 separate and cut off hedges 24,25,30,31 the insulation from a cable conductor located between them.

Skalverktyget blir därigenom ett universalverktyg,@med vilket man kan avlägsna både ytterisoleringen och isoleringen på de enskilda ledarna efter vartannat.The scaling tool thereby becomes a universal tool, @ with which you can remove both the outer insulation and the insulation on the individual conductors after every other.
