Description
25 30 35 526 297 2 =° Kontaktstyckets klämmande del är bildad som en ringformad rygg, vilken utgör bakre änden av ett främre mot spetsen avsmalnande parti av kontaktstycket, varvid kontaktstycket har en längdmittdel med en runtomgàende urtagning, vilken följer efter ryggen för att radiellt avlasta trådarna. I urtagningens bakre ände finns en framàtriktad runtomgàende försânkning i vilken ledaretrådarnas änddelar emottas. Här- igenom minskar risken för att tràdarnas änddelar skall kila in sig mot den klämmande ryggen vid kontaktstyckets urdrag- ning ur hylsan. Åtminstone de delar av kontaktstycket som införes i hylsan är lämpligen utförda av elastiskt material, som kan defor- meras radiellt av hylsan. Försänkningen övertäckes radiellt av en tunga, vars ytteryta företrädesvis vidgar sig koniskt i riktning mot kontaktstyckets bakre ände, varvid den koniska ytan företrädesvis sträcker sig bakåt till omrâdet för kontaktstyckets bakre vidgade kanaldel, som emottar den främre änden av kabelns kabelhölje. The clamping part of the contact piece is formed as an annular ridge, which forms the rear end of a front portion of the contact piece tapered towards the tip, the contact piece having a longitudinal middle part with a circumferential recess, which follows the back to radially relieve the threads. At the rear end of the recess there is a forward-facing circumferential depression in which the end portions of the guide wires are received. This reduces the risk of the end parts of the threads wedging against the clamping back when the connector is pulled out of the sleeve. At least the parts of the contact piece which are inserted into the sleeve are suitably made of elastic material, which can be deformed radially by the sleeve. The recess is radially covered by a tongue, the outer surface of which preferably widens conically towards the rear end of the connector, the conical surface preferably extending rearwardly to the area of the rear widened channel portion of the connector which receives the front end of the cable sheath.
I det föredragna fallet att hylsan har sin främre ände avskärmad av en ändvägg, kan kontaktstyckets främre ände, kring vilken ledaretràdarna år omvikta, pressa dessa trådar till kontakt med hylsans ändvägg.In the preferred case that the sleeve has its front end shielded by an end wall, the front end of the connector, around which the conductor wires are folded, can press these wires into contact with the end wall of the sleeve.
Eventuellt kan kontaktstyckets bakre ände vara försedd med ett ändavsnitt med företrädesvis underskuren omkretsyta till bildning av ett fingergrepp som underlättar utdragning av kontaktstycket tillsammans med kabeln ur hylsan.Optionally, the rear end of the connector may be provided with an end section with preferably undercut circumferential surface to form a finger grip which facilitates pulling of the connector together with the cable from the sleeve.
Uppfinningen kommer i de följande att beskrivas i exempel- form med hänvisning till den bilagda ritningen.The invention will be described in the following by way of example with reference to the accompanying drawing.

Fig. 2 visar en axialsektion motsvarande fig. 1, men med kontaktstycket fullt infört i hylsan.Fig. 2 shows an axial section corresponding to Fig. 1, but with the connector fully inserted into the sleeve.
Pâ fig. 1 visas ett väsentligen rotationssymmetriskt kon- taktstycke 1, vilket har en central genomloppskanal omfat- tande en främre del 10 och en bakre del 11 med en diameter En kabel 2 visas omfatta ett kabelhölje 21 och en màngträdig ledare 22.Fig. 1 shows a substantially rotationally symmetrical contact piece 1, which has a central passage channel comprising a front part 10 and a rear part 11 with a diameter. A cable 2 is shown comprising a cable sheath 21 and a multi-stranded conductor 22.
Kanaldelen 10 har en diameter som är anpassad till ledaren som är större än den främre delen 10. 22, och delen 11 har en diameter som är anpassad till ytcerdiameuern för kabeln z inklusive höijet 21, så acc kabeln kan övergången inskjutas sà att dess främre ände stöter an mot mellan kanaldelarna 10, 11.The channel part 10 has a diameter which is adapted to the conductor which is larger than the front part 10. 22, and the part 11 has a diameter which is adapted to the surface diameter of the cable z including the height 21, so that the cable can be inserted so that its front end abuts between the channel parts 10, 11.
Man kan se att kopplingsstyckets främre ände har en nos 16 sig fràn nosen 16 i riktning bakåt till en kläm- rygg 12 med ringa axiell längd, efter vilken följer en ur- tagning 3 i ett längdmittomràde av kontaktstycket. och vidgar Vid urtagningens bakre ände finns en framàtriktad runtom- igàende försänkning 14, som övertäckes av en framätriktad runtomgàende tunga 15. Man kan se att kabeln 2 har sin främre ände avskalad utmed en sådan sträcka att ledare- tràdarna sträcker sig tillbaka runt kontaktstyckets nos över ryggen 12 längs urtagningens bottenyta 13, sä att tràdändarna 23 är avslutade vid försänkningens 14 botten.It can be seen that the front end of the coupling piece has a nose 16 extending from the nose 16 in the rearward direction to a clamping back 12 of small axial length, followed by a recess 3 in a longitudinal center area of the connector. and widening At the rear end of the recess there is a forward-facing circumferential recess 14, which is covered by a forward-facing circumferential tongue 15. It can be seen that the cable 2 has its front end stripped along such a distance that the conductor wires extend back around the nose of the connector over the ridge 12 along the bottom surface 13 of the recess, so that the wire ends 23 are terminated at the bottom of the recess 14.
Man kan se att den koniska ytan 17 vid kontaktstyckets nosparti samverkar med hylsans 30 mynningskant och medger en inklâmning av ledaren 22 i kanalen 10, varvid en i förväg bestämd radiell klämning etableras mellan ryggen 12 och hylsans mantelvägg 31, för etablering av en definierad kontakt mellan ledaretràdarna och hylsan. Vidare kan man se att kontaktstyckets bakre del 4 har ett utvändigt bakåt sig vidgande koniskt avsnitt 18, som sträcker sig från tungans 15 främre ände och bakåt till en axialposition i området för övergången mellan kanaldelarna 10 och ll. Den koniska ytan 18 följs av ett cylindriskt avsnitt. 00 0000 oo 0 n o o 000 000 C000 0 O I I o to II 10 15 20 25 30 35 526 297 4 r,- Pà fig. 1 och 2 visas även en utföringsform i vilken kontaktstycke följs av en ringformig del 5 med förstorad diameter och en framätvänd avfasad fingergripyta 51, som underlättar utdragning av kontaktstycket 1 ur hylsan 30.It can be seen that the conical surface 17 at the nose portion of the connector cooperates with the mouth edge of the sleeve 30 and allows a clamping of the conductor 22 in the channel 10, whereby a predetermined radial clamp is established between the back 12 and the sleeve wall 31, to establish a defined contact between the conductor wires and the sleeve. Furthermore, it can be seen that the rear part 4 of the connector has an externally rearwardly widening conical section 18, which extends from the front end of the tongue 15 and backwards to an axial position in the area of the transition between the channel parts 10 and 11. The conical surface 18 is followed by a cylindrical section. 00 0000 oo 0 noo 000 000 C000 0 OII o to II 10 15 20 25 30 35 526 297 4 r, - Figures 1 and 2 also show an embodiment in which the contact piece is followed by an annular part 5 with an enlarged diameter and a forward-facing chamfered finger grip surface 51, which facilitates pulling of the connector 1 out of the sleeve 30.
Diametern för kontaktstyckets bakre del är vald för att säkerställa en radiell komprimering av kabeln 2 inklu- derande höljet 21, av sådan art att à ena sidan hylsans 4 omkretsyta tätar mot hylsans mantelvägg 31 och vidare kanalväggen 11 tätar runt omkretsen av kabelns 21 ytteryta och vidare kabelhöljets 21 inneryta tätar mot ledaren och komprimerar dess trådar radiellt för minimering av risken för axiell fuktgörelse genom kabeln.The diameter of the rear part of the connector is chosen to ensure a radial compression of the cable 2 including the housing 21, of such a nature that on one side the circumferential surface of the sleeve 4 seals against the jacket wall 31 of the sleeve and further the channel wall 11 seals around the circumference of the outer surface 21 the inner surface of the cable sheath 21 seals against the conductor and compresses its wires radially to minimize the risk of axial wetting through the cable.
Av fig. 2 kan man utläsa att konytan 18 eventuellt kan vara anordnad för att radiellt eliminera den runtomgàende för- sänkningen 14, för fastklämning av tràdändarna 23 däri, exempelvis genom radiell nedtryckning eller nedfällning av tungan 15 mot urtagningens bottenyta 13.From Fig. 2 it can be seen that the cone surface 18 may optionally be arranged to radially eliminate the circumferential recess 14, for clamping the wire ends 23 therein, for instance by radial depression or lowering of the tongue 15 against the bottom surface 13 of the recess.
Genom att säkerställa en begränsad axiell längd för ryggen 12 kan man uppnå ett högt uttryck mellan trådarna och hyls- väggen 31 samtidigt som man minskar risken för att trådarna axiellt skall förskjutas relativt hylsan 30 vid kontakt- styckets äterdragning från hylsan. I den visade utförings- formen är hylsans 30 främre ände tätt försluten av en änd- vägg 32, vilken pà sin utsida har en infästningshylsa 40 för en ledare 22' tillhörande en anslutningskabel 2'.By ensuring a limited axial length for the back 12, a high expression between the wires and the sleeve wall 31 can be achieved while reducing the risk of the wires being axially displaced relative to the sleeve 30 when the connector is retracted from the sleeve. In the embodiment shown, the front end of the sleeve 30 is tightly closed by an end wall 32, which on its outside has a fastening sleeve 40 for a conductor 22 'belonging to a connecting cable 2'.
Ledaren 22' kan infästas i hylsan 40 pà lämpligt sätt, exempelvis medelst en klämskruv 41.The conductor 22 'can be fastened to the sleeve 40 in a suitable manner, for example by means of a clamping screw 41.
Hylsan 30 visas tätt infäst i en motsvarande öppning genom en vägg 50. Av fig. 2 framgår att kontaktstycket även säkerställer kontakt för ledaretràdarna i närgränsnings- omràdet mellan nosen 16 och ändväggen 32. Hylsan 30 består lämpligen av elektriskt ledande material. 0 0 I I I 00 OO 0 000 0000 0 I I 00 00 0 n 0000 0 0 00 0 O l 0 000 0 0 0 0 0 0 OI QIO OI .Ü 10 526 297 s Innerytan av hylsans mantelvägg 31 kan vara klädd med ett skikt av aktiverbart lim, exempelvis mikrosfärer som är fyllda med limkomponenter och som bryts sönder vid kontakt med kabelhöljet, för att säkerställa en fast förankring av kabeln i kontaktstycket. Alternativt kan innerytan av mantelväggen vara ràgjord eller bestå av lämpligt material för att erbjuda en säker och enkel limförbindning eller svetsförbindning till kabelhöljet, om så önskas.The sleeve 30 is shown tightly attached to a corresponding opening through a wall 50. Fig. 2 shows that the contact piece also ensures contact for the conductor wires in the proximity area between the nose 16 and the end wall 32. The sleeve 30 suitably consists of electrically conductive material. 0 0 III 00 OO 0 000 0000 0 II 00 00 0 n 0000 0 0 00 0 O l 0 000 0 0 0 0 0 0 OI QIO OI .Ü 10 526 297 s The inner surface of the sleeve shell wall 31 may be covered with a layer of activatable adhesive, for example microspheres which are filled with adhesive components and which break on contact with the cable sheath, to ensure a firm anchoring of the cable in the connector. Alternatively, the inner surface of the jacket wall may be roughened or consist of suitable material to provide a secure and simple adhesive connection or weld connection to the cable sheath, if desired.
