Opfindelsen angår en kapselsammenstilling af den i krav l*s indledning angivne art.The invention relates to a capsule assembly of the kind specified in the preamble of claim 1.

De mange koblingselementer, der anvendes til at forbinde trådledere i et telefonkredsløb, eksempelvis splejsnings- eller 5 laskehuse, med eller uden tryk, eller telefonstativer, må beskyttes mod korrosion som følge af fugtindtrængning. Denne beskyttelse kan ikke bekvemt tilvejebringes ved indkapsling i et selvhærdende indkapslingsmateriale i en kapsel af den art, der kendes fra US patent nr. 2.862.042, nr. 2.908.744, 10 nr. 2.967.795 og nr. 3.419.669 til brug ved splejsning af underjordskabler eller ved indkapsling i et udtageligt indkapslingsmateriale i en kapsel, som beskrevet i US patentskrift nr. 3.836.694, på grund af de forholdsvis store dimensioner for disse kapsler i forhold til splejshuses eller stativers 15 normale størrelser.The many coupling elements used to connect wire conductors in a telephone circuit, for example, splicing or welding housings, with or without pressure, or telephone racks, must be protected against corrosion due to moisture penetration. This protection cannot conveniently be provided by encapsulation in a self-curing encapsulating material in a capsule of the kind known from US Patent Nos. 2,862,042, Nos. 2,908,744, 10 Nos. 2,967,795 and 3,419,669 for use. by splicing underground cables or by enclosing in a removable encapsulating material in a capsule, as described in U.S. Patent No. 3,836,694, due to the relatively large dimensions of these capsules relative to the normal sizes of splicing housings or racks.

Sådanne koblingselementer er blevet indkapslet enkeltvis i et sejt flydende indlejringsmateriale ved at anbringe et tilkoblet koblingselement i en fleksibel pose, der delvis er fyldt med indlejringsmateriale, hvorefter indlejringsmaterialet 20 pakkes rundt om koblingselementet,og den åbne ende af posen fastgøres omkring de ledninger, der fører til koblingselementet, medens disse er samlet i et bundt. Dette system kræver imidlertid et stor kvantum indlejringsmateriale i forhold til koblingselementets volumen og tilstrækkelig længde i hver af 25 de splejsede ledere til at danne et lederbundt. Det resulterende indkapslede koblingselement er stort sammenlignet med dimensionerne af selve koblingselementet, således at det optager kostbart volumen i vedligeholdelsesboksen, f.eks. splejsehuset eller stativet. Den rette fordeling af indlej-30 ringsmateriale rundt om koblingselementet afhænger af operatørens fagkundskab.Such coupling elements have been individually encapsulated in a cool liquid embedding material by placing a coupled coupling element in a flexible bag partially filled with embedding material, after which the embedding material 20 is wrapped around the coupling element and the open end of the bag is secured around the joints. to the coupling element while assembled into a bundle. However, this system requires a large amount of embedding material relative to the volume of the coupling element and sufficient length in each of the spliced conductors to form a conductor bundle. The resulting enclosed coupling element is large compared to the dimensions of the coupling element itself, so that it takes up precious volume in the maintenance box, e.g. the splice housing or rack. The proper distribution of embedding material around the coupling element depends on the skill of the operator.

Fra US PS 3.597.528 kendes en fremgangsmåde til at indkapsle forbindelse mellem et antal ledere i et elektrisk koblings- 2From US PS 3,597,528 there is known a method of encapsulating a connection between a plurality of conductors in an electrical coupling 2.

element. Der er her tale om en kapselsammenstilling, som omfatter en fatning, som har frie åbne ender og er tilpasset koblingselementets sidevægge. I fatningen anbringes der en så stor mængde sejt flydende vandafstødende dielektrisk 5 indlejringsmateriale at fatningen inklusive kanalerne i koblingselementet bliver fyldt, efter at koblingselementet er anbragt i fatningen.element. This is a capsule assembly which includes a socket having free open ends and adapted to the side walls of the coupling element. In the socket, such a large amount of cool liquid water repellent dielectric embedding material is placed that the socket including the channels in the coupling element is filled after the coupling element is placed in the socket.

Det at tvinge meget sejt flydende indlejringsmateriale fuldstændig gennem de små labyrintiske indre kanaler i et kob-10 lingselement og forbi ledere, som er fastgjort i dette, kræ ver et betydeligt tryk, specielt for store koblingselementer. Når et koblingselement skal føres ind i en fatning, findes der kun små udvendige flader af koblingselementet, som tryk kan overføres til fra en persons tommelfingre eller andre 15 fingre, noget som gør en manuel sammenstilling vanskelig, samtidig med at personen kan komme i berøring med de udragende ledere og eventuelt bøje og skade disse.Completely forcing very cool liquid embedding material through the small labyrinthine inner channels of a coupling element and past conductors attached thereto requires considerable pressure, especially for large coupling elements. When a coupling element is to be inserted into a socket, there are only small external surfaces of the coupling element to which pressure can be transferred from a person's thumb or other 15 fingers, making a manual assembly difficult while allowing the person to come in contact with the projecting leaders and possibly bending and injuring these.

Det er den foreliggende opfindelses formål at anvise en kapselsammenstilling, som gør indpresningen af koblingsele-20 mentet i fatningen lettere samtidig med, at kanalerne i koblingselementet bliver fuldstændigt fyldt med indlejringsmaterialet uden brug af overskydende mængde af dette materiale eller tab af plast omkring koblingselementet.It is an object of the present invention to provide a capsule assembly which facilitates the pressing of the coupling element into the socket while completely filling the channels of the coupling element with the embedding material without the use of excess amount of this material or loss of plastic around the coupling element.

Dette formål er for en kapselsammenstilling af den i indled-25 ningen omtalte art tilgodeset ved, at den er ejendommelig ved det i den kendetegnende del af krav 1 anførte.This object is met for a capsule assembly of the kind mentioned in the introduction in that it is peculiar to that of the characterizing part of claim 1.

De modstående vægtstænger, som er anbragt ved den åbne ende af fatningen, og som må opbygges således, at de kommer i indgreb med den ende af koblingselementet, som ligger ved siden 30 af de udragende ledere, giver en mekanisk kraftforøgelse til inddrivning af koblingselementet i indlejringsmaterialet i fatningen. Inddrivningen kan således udføres manuelt på en 3 146870 kraftbesparende og effektiv måde, uden at den person, som udfører sammenpresningen, kommer i berøring med de udragende ledere og bøjer disse.The opposing barriers, which are located at the open end of the socket, and which must be so constructed as to engage the end of the coupling member adjacent to the protruding conductors, provide a mechanical force increase to drive the coupling member into the the embedding material in the socket. Thus, the drive-in can be performed manually in a power-saving and efficient manner, without the person carrying out the compression coming into contact with the projecting conductors and bending them.

Desuden tjener vægtstængerne til at låse koblingselementet 5 i fatningen.In addition, the levers serve to lock the clutch member 5 in the socket.

Hensigtsmæssigt er fatningen formet til at passe til sidevæggene af koblingselementet således, at dens inderflader i nærheden af den åbne ende giver en snæver giidepasning rundt langs koblingselementets vægge (dvs. ca. 0,013 - 0,025 10 cm frigang),skønt små spor i overfladen af væggene kan til lades. I fatningen indfører man sejt flydende dielektrisk vanduopløseligt indlejringsmateriale i en mængde, der er tilstrækkelig til at fylde fatningen inklusive kanalerne i koblingselementet, efter at koblingselementet er indført et 15 i forvejen bestemt stykke i fatningen. Koblingselementet fø res delvis ind i fatningen gennem den åbne ende indtil den ende, som ligger modsat de udragende ledere, kommer i berøring med indlejringsmaterialet, og ved hjælp af vægtstængerne på fatningen udøves der tilstrækkelig kraft mellem fat-20 ningen og den frilagte ende af koblingselementet til at pres se koblingselementet mod bunden af fatningen og presse indlej ringsmaterialet gennem de indre kanaler i koblingselementet, idet koblingselementet virker som stempel. Indlejringsmaterialet vil flyde gennem kanalerne og fylde dem helt, da 25 disse yder en mindre modstand mod indlejringsmaterialets bevægelse end mellemrum mellem fatningens inderflader og koblingselementets vægge.Conveniently, the socket is shaped to fit the side walls of the coupling element such that its inner surfaces near the open end provide a narrow guide fit around the walls of the coupling element (i.e., about 0.013 - 0.025 10 cm clearance), although small grooves in the surface of the walls can be charged. In the socket, cool liquid dielectric water insoluble embedding material is introduced in an amount sufficient to fill the socket including the channels in the coupling element after the coupling element is inserted a predetermined portion in the socket. The coupling element is partially inserted into the socket through the open end until the end opposite the protruding conductors comes into contact with the embedding material, and by means of the weights on the socket sufficient force is applied between the socket and the exposed end of the coupling element. for pressing the coupling member towards the bottom of the socket and pressing the embedding material through the inner channels of the coupling member, the coupling member acting as a piston. The embedding material will flow through the ducts and fill them completely as these provide less resistance to the movement of the embedding material than spaces between the inner surfaces of the socket and the walls of the coupling element.

Kapselsammenstillingen kræver brug af kun ubetydeligt mere indkapslingsmateriale end, hvad der skal til for at fylde 30 mellemrummene i koblingselementet. Både selvhærdende og ikke hærdende indlejringsmaterialer kan benyttes. Når der benyttes et ikke hærdende indlejringsmateriale, kan man let skifte et indkapslet koblingselement ud ved slet og ret at 4 146870 trække koblingselementet ud af fatningen. Når den ønskede forandring er udført, kan man lukke koblingselementet igen ved ganske enkelt at anbringe indlejringsmaterialet i fatningen og genindsætte koblingselementet.The capsule assembly requires the use of only slightly more encapsulating material than what is needed to fill the 30 spaces in the coupling element. Both self-curing and non-curing embedding materials can be used. When a non-hardening embedding material is used, it is easy to replace an encapsulated coupling element by simply pulling the coupling element out of the socket. When the desired change has been made, the coupling element can be closed again by simply placing the embedding material in the socket and reinserting the coupling element.

5 Indlejringsmaterialer, der er fundet særlig velegnede, ind befatter sådanne,som har en stor dielektrisk fasthed og tiksotrope egenskaber og en statisk viskositet" i området fra ca. 1 til ca. 1,5 million cP, og en aflæsning på en gennemtrængningsmåler i området fra 200-300. Som eksempler kan 10 nævnes et siliconefedt, der markedsføres under betegnelsen "DC-2" af Dow Corning, Midland, Michigan, og et fedt markedsført under betegnelsen "DSG Sealant Grease" af Minnesota Mining and Manufacturing Company, St. Paul, Minnesota.Embedding materials found to be particularly suitable include those having a high dielectric strength and thixotropic properties and a static viscosity "in the range of about 1 to about 1.5 million cP, and a reading on a penetration meter in the range. Examples include 10 a silicone grease marketed under the designation "DC-2" by Dow Corning, Midland, Michigan, and a grease marketed under the designation "DSG Sealant Grease" by the Minnesota Mining and Manufacturing Company, St. Paul, Minnesota.

Den i fig« 1-4 viste faste udførelsesform for kapselsammen-5 stillingen 10 ifølge opfindelsen er beregnet til brug ved ind kapsling af et koblingselement 12 (fig. 2, 3 og 4) med indre kanaler 13, der kommunikerer indbyrdes mellem elementets ender 14, ved at koblingselementet 12 på højkant presses ind i en tætsluttende fatning 15 i kapselsammenstillingen 10, der er 10 fyldt med et sejt flydende dielektrisk vandskyende indlej ringsmateriale. Når koblingselementet 12 presses ind i fatningen 15, tvinges indlejringsmaterialet ind i kanalerne 13 og ekstruderes derigennem til at fylde hulrummene i koblingselementet 12 - se fig, 3 og 4.The solid embodiment of the capsule assembly 10 shown in Figs. 1-4 is intended for use in encapsulating a coupling element 12 (Figs. 2, 3 and 4) with inner channels 13 communicating with each other between the ends 14 of the element. , by pushing the coupling element 12 on a high edge into a tightly sealed socket 15 in the capsule assembly 10, which is 10 filled with a cool liquid dielectric water repellent embedding material. When the coupling element 12 is pressed into the socket 15, the embedding material is forced into the channels 13 and extruded therethrough to fill the voids in the coupling element 12 - see Figures 3 and 4.

15 Koblingselementet 12 er af den i US-PS 3.708.779 beskrevne art og i hovedsagen rektangulært og har opretstående sidevægge 16, der udstrækker sig mellem elementets overfor hinanden liggende ender 14. Koblingselementet 12 har adskilbare isolerende hoveddele, der - efter samling - afgrænser et 20 antal indre ledertrådoptagende kanaler 13, der forløber mel lem enderne 14. Et antal ledende kontaktelementer 18, der er slidset til at danne fjedrende ledermodtagende fingre, er monteret i den ene af hoveddelene med udtagningerne anbragt på linie med kanalerne 13. Ender af lederlængden 19, der 25 skal forbindes elektrisk, anbringes i de dele af kanalerne 13, der er udformet i den ene af hoveddelene, og koblingselementet 12 samles, således at kontaktelementerne 18's fingre fjedrende indgriber med lederne 19 for elektrisk at sammenkoble disse i et forudbestemt mønster. Koblingselementet in-30 deholder desuden skæreklinger 20, som - når forbindelsesled det er samlet - afskærer et stykke af hver leder 19 nær det kontaktelement 18, der er indgreb dermed på en sådan måde, at de afskårne lederender kan trækkes fra koblingselementet 12. Skæreklingerne 20 er anbragt på en sådan måde, at de 35 elektrisk bundne ledere kun strækker sig ud fra den ene ende 146870 6 14 af koblingselementet 12.The coupling element 12 is of the kind described in U.S. Pat. No. 3,708,779 and generally rectangular and has upright side walls 16 extending between the opposite ends of the element 14. The coupling element 12 has separable insulating main parts which - after assembly - define a 20 a plurality of conductor wire receiving channels 13 extending between the ends 14. A plurality of conductive contact members 18 slotted to form resilient conductor receiving fingers are mounted in one of the main portions with the recesses aligned with the channels 13. End of conductor length 19 to be electrically connected 25 are placed in the portions of the ducts 13 formed in one of the main portions and the coupling element 12 is assembled so that the fingers of the contact elements 18 resiliently engage the conductors 19 to electrically couple them in a predetermined pattern. The coupling element further includes cutting blades 20 which - when connected together - cut off a piece of each conductor 19 near the contact element 18 which is engaged thereby in such a way that the cut conductor ends can be pulled from the coupling element 12. The cutting blades 20 is arranged in such a way that the electrically connected conductors extend only from one end of the coupling element 12.

Kapselsairanenstillingen 10 har vinkelret på hinanden stående sidevægge 26, endevægge 27, og en bundvæg 28. De indre flader af disse vægge danner fatningen 15, som har en fri af-5 lang rektangulær åben ende 30 o De indre flader af side- og endevæggene 26 og 27 er tilpasset koblingselementets sidevægge 16 (idet der dog er et spillerum på 0,013 til 0,025 cm mellem sidevæggene 16 og side- og endevæggene 26 og 27) for at hindre, at en betydende mængde indlejringsmateriale trænger 10 ind mellem den, da dette materiale lettere ekstruderes gen nem kanalerne 13, når koblingselementet 12 presses ind i fatningen 15.The capsule arrangement 10 has perpendicular to each other side walls 26, end walls 27, and a bottom wall 28. The inner faces of these walls form the socket 15, which has a free elongated rectangular open end 30 o The inner faces of the side and end walls 26 and 27 are adapted to the sidewalls 16 of the coupling element (however, there is a clearance of 0.013 to 0.025 cm between the sidewalls 16 and the side and end walls 26 and 27) to prevent a significant amount of embedding material from penetrating it as this material facilitates is extruded through the channels 13 as the coupling element 12 is pressed into the socket 15.

Kapselsairanenstillingen 10 har også et par vægtstænger 32, der mekanisk forøger kraften, når koblingselementet presses 15 ind i fatningen 15 og tjener til at låse koblingselementet deri o Vægtstængerne 32 er hængslet overfor hinanden ved den åbne ende af fatningen og på en sådan måde, at de kan svinges om hver sin akse ved kanten af endeåbningen 27. Hver vægtstang 32 har et ydre endeparti 34, der er beregnet til 20 manuel betjening, og en plan drivflade 35 nær den åbne ende 30 af fatningen 15. Vægtstangsarmene kan drejes fra en første ydre position, se fig. 1 og 2, hvor de er adskilt så meget, at fatningens åbne ende 30 er helt åben således, at koblingselementet 12 delvis kan indføres, til en anden posi-25 tion, hvor drivfladerne 35 lægger sig an mod den frie ende af det i fatningen 15 delvis indførte koblingselement langs overfor liggende kanter, og drive koblingselementet helt ind i fatningen 15. De modstående vægtstænger 32 kan let presses mod hinanden af brugeren, og afstanden fra aksen til driv-30 fladen 35 af hver vægtstang32 er forholdsvis kort sammen lignet med længden af vægtstangen 32 fra aksen til dens ydre ende 34 således, at vægtstangen 32 giver en kraftforøgelse, der gør det muligt at presse koblingselementet ind i fatningen 15.The capsule arrangement 10 also has a pair of weights 32 which mechanically increase the force as the coupling member 15 is pressed into the socket 15 and serves to lock the coupling member therein. The weights 32 are hinged to each other at the open end of the socket and in such a way that they can be pivoted about its axis at the edge of the end aperture 27. Each bar 32 has an outer end portion 34 intended for 20 manual operation and a flat drive surface 35 near the open end 30 of the socket 15. The bar arms can be pivoted from a first outer position, see fig. 1 and 2, where they are separated so much that the open end 30 of the socket is fully open so that the coupling element 12 can be partially inserted, to another position, where the driving surfaces 35 abut the free end of it in the socket. 15 partially inserted coupling member along opposite edges, driving the coupling member fully into the socket 15. The opposing barriers 32 can be easily pressed against each other by the user, and the distance from the axis to the drive surface 35 of each bar 32 is relatively short compared to the length. of the lever 32 from the shaft to its outer end 34 such that the lever 32 provides a force increase allowing the clutch member to be pressed into the socket 15.

Kapselsammenstillingen 10 er formet ud i ét af et polymert materiale, fortrinsvis polypropylen» Rotationsaksen for hver vægtstang 32 er tilvejebragt ved hjælp af en første tynd hængselspart 38 af det støbte materiale mellem vægtstangen 5 32 og endevæggene 27 - se fig. 2. Den tynde hængselspart 38 forskydningshærder under deformation og giver et over for brud forholdsvis modstandsdygtigt og fleksibelt hængsel mellem vægtstangen 32 og den pågældende endevæg 27.The capsule assembly 10 is formed into one of a polymeric material, preferably polypropylene. 2. The thin hinge portion 38 shear hardens during deformation and provides a relatively resilient and flexible hinge between the bar 32 and the end wall 27 concerned.

Hver vægtstang 32 har en første vægtstangsdel 40 og en anden 10 vægtstangsdel 42, og delene er indbyrdes forbundet ved hjælp af en anden tynd hængselspart 44 svarende til og beliggende parallelt med den første tynde hængselspart 38. Den første del 40 danner drivfladen 35 og har et par overfor hinanden beliggende hager 46, der forløber langs overfor hinanden kan-15 ter af drivfladen 35 fra rotationsaksen, som, idet den dan ner en ret vinkel med drivfladen 35, rager frem mod den åbne ende 30 af fatningen 15. Hagerne 46 på hver vægtstang 32 er indrettet til at indgribe med et par låseribber 48, der rager ud fra de modsatte sider 26 af fatningen nær dens 20 åbne ende 30 og således låser den første vægtstangsdel 40 i dennes anden position.Each bar 32 has a first bar portion 40 and a second barbell portion 42, and the portions are interconnected by a second thin hinge portion 44 corresponding to and located parallel to the first thin hinge portion 38. The first portion 40 forms the drive surface 35 and has a a pair of opposite hooks 46 extending along opposite edges of the driving surface 35 from the axis of rotation, which, at a right angle to the driving surface 35, protrudes toward the open end 30 of the socket 15. The hooks 46 on each bar 32 is adapted to engage with a pair of locking ribs 48 projecting from the opposite sides 26 of the socket near its open end 30, thus locking the first bar portion 40 in its second position.

Den anden del 42 af hver vægtstang har et par trekantede sideflanger 50 med indre endekanter 52 nær ved den fra drivfladen 35 bortvendte flade på den første vægtstangsdel 40.The second portion 42 of each bar has a pair of triangular side flanges 50 with inner end edges 52 adjacent the surface facing away from the drive surface 35 on the first bar portion 40.

25 Disse endekanter 52 lægger sig mod og presser den nært belig gende første vægtstangsdel 40 mod dennes anden position, når de ydre vægtstangsdele 42 presses mod hinanden for at drive koblingselementet ind i fatningen 15. Efter at den første vægtstangsdel 40 er fastlåst i sin anden position, 30 danner den anden hængselspart 44 en passende svækningslinie for let afrivning eller bortskæring af den anden vægtstangsdel 42, om dette skulle ønskes.These end edges 52 lie against and press the proximate first lever portion 40 toward its second position as the outer lever parts 42 are pressed against each other to drive the coupling member into the socket 15. After the first lever portion 40 is locked in its second position. 30, the second hinge portion 44 forms a suitable line of weakening for easy tearing or cutting of the second lever portion 42, should this be desired.

I fig» 5 og 6 er der vist en anden udførelsesform for en 146870 δ kapselsammenstilling 60. Ligesom kapselsammenstillingen 10 er kapselsammenstillingen 60 også beregnet til brug ved indkapsling af et koblingselement med indre kanaler, som kommunikerer indbyrdes mellem elementets ender ved på høj-5 kant at presse koblingselementet ind i en tætsluttende fatning 61, der er fyldt med et indlejringsmateriale. Kapsel-sammenstillingen 60 er specielt beregnet til at indkapsle koblingselementet, hvor sidevægslængden er meget større end deres bredde og har et par vægtstænger 62, der bidrager til 10 at presse koblingselementet ind i fatningen 61, ved at lægge sig an mod den frilagte ende af koblingselementet langs dettes længste kanter.In Figs. 5 and 6, another embodiment of a capsule assembly 60 is shown. Like the capsule assembly 10, the capsule assembly 60 is also intended for use in encapsulating an inner channel coupling element which communicates between the ends of the element at a high 5 edge. pressing the coupling member into a tightly sealed socket 61 filled with an embedding material. The capsule assembly 60 is specially designed to encapsulate the coupling member, the sidewall length being much greater than their width and having a pair of weights 62 which contribute to pressing the coupling member into the socket 61 by abutting the exposed end of the coupling member along its longest edges.

Ligesom kapselsammenstillingen 10 indeholder kapselsammenstillingen 60 vinkelret på hinanden stående sidevægge 66 og ende-15 vægge 67 samt en bundvæg 68, hvis indre overflader danner fatningen 61, som har en aflang rektangulær fri åben ende 70.Like the capsule assembly 10, the capsule assembly 60 includes perpendicular to each other side walls 66 and end walls 67 as well as a bottom wall 68, the inner surfaces of which form the socket 61, which has an elongated rectangular free open end 70.

De indre overflader af side- og endevæggene 66 og 67 passer til sidevæggene af et koblingselement, til hvilket konstruktionen er dimensioneret til effektivt at forhindre bevægelse 20 eller forskydning af mellemliggende indlejringsmateriale og tvinge det gennem koblingselementets kanaler, når koblingselementet presses ind i fatningen 61.The inner surfaces of the side and end walls 66 and 67 correspond to the side walls of a coupling element, to which the structure is designed to effectively prevent movement 20 or displacement of intermediate embedding material and force it through the channels of the coupling element as the coupling element is pressed into the socket 61.

Kapselsammenstillingen 60 inklusive vægtstængerne 62 er formet ud i ét, fortrinsvis af polypropylen. Rorationsaksen for 25 hver vægtstang 60 er tilvejebragt ved hjælp af en tynd hængselspart 65 af polypropylen mellem vægtstangen 62 og den ende af sidevæggene 66 nær den åbne ende 70 af fatningen 61. Vægtstængerne 62 er monteret med modsat orientering. Hver vægtstang har en plan del, hvis ydre ende 74 er beregnet 30 til manuel betjening. Et antal indbyrdes adskilte trekantede fremspring 75 rager ud fra den plane del mod den åbne ende 70 af fatningen 61. Hvert fremspring 75 på hver vægtstang har flugtende indre endeflader, således at disse danner en drivflade 76 nær den åbne ende 70 af fatningen 61. Vægt-35 stængerne kan svinges fra en første position med drivfladerne 9 146870 76 beliggende i afstand fra den åbne 70 af fatningen 61 som dermed er helt fri til* at et koblingselement delvis kan indføres i fatningen til en anden position, ved hvilken drivfladerne 76 indgriber med den frie ende af det koblingsele-5 ment, der delvis er optaget i fatningen langs modsatte kan ter, og vil drive koblingselementet 12 helt ind i fatningen 61. Afstanden fra aksen til drivfladen 76 på hver vægtstang er forholdsvis kort sammenlignet med længden af vægtstangen fra aksen til den ydre ende 74, således at vægtstangen giver 10 en kraftforøgelse, der gør det lettere at presse koblingsele mentet ind i fatningen 61. Midt på kapselens længde er de modstående vægtstænger 62 udsparede således, at en bruger vil søge at presse vægtstængerne 62 i fire parter med maximal vægtstangslængde. Derved fordeles den tilførte kraftpåvirk-15 ning mere ensartet hen ad koblingselementet under dets indfø ring i fatningen uden binding eller fastkilning.The capsule assembly 60 including the weights 62 is formed integrally, preferably of polypropylene. The axis of rotation of each lever 60 is provided by a thin hinge portion 65 of polypropylene between the lever 62 and that end of the side walls 66 near the open end 70 of the socket 61. The levers 62 are mounted in opposite orientation. Each lever has a planar portion, the outer end 74 of which is intended for manual operation. A plurality of spaced apart triangular projections 75 protrude from the planar portion toward the open end 70 of the socket 61. Each projection 75 on each bar rod has flushing inner end faces so as to form a driving surface 76 near the open end 70 of the socket 61. Weight The -35 rods may be pivoted from a first position with the drive surfaces 9 spaced apart from the open 70 by the socket 61 which is thus completely free to allow a coupling element to be partially inserted into the socket to a second position at which the drive surfaces 76 engage the free end of the clutch member partially accommodated in the socket along opposite ends and will drive the clutch member 12 fully into the socket 61. The distance from the axis to the drive surface 76 on each bar is relatively short compared to the length of the bar from the axis to the outer end 74 so that the lever 10 provides an increase in force which makes it easier to push the coupling element into the socket 61. Mid length of the capsule e The opposing barbs 62 are recessed so that a user will seek to squeeze the barbs 62 into four parts with maximum bar length. Thereby, the applied force distribution is distributed more uniformly across the coupling element during its introduction into the socket without bonding or wedging.

Fig. 7 viser en tredje udførelsesform for en kapselsammenstilling 80 ifølge opfindelsen. Denne svarer til den i fig.FIG. 7 shows a third embodiment of a capsule assembly 80 according to the invention. This is similar to that of FIG.

5 og 6 viste kapselsammenstilling 60 derved,at den indehol-20 der et par vægtstænger 81 til at presse et koblingselement ind i en fatning 83, idet vægtstængerne 81 er indrettet til at lægge sig an mod koblingselementet ved dettes længste kanter. En første del 84 af kapselsammenstillingen 80, som danner fatningen 83, kan skilles fra en anden del 85, der 25 indeholder vægtstængerne 81 og ydervægge til centrering og understøtning af den første del 84. Når disse dele 84 og 85 sættes sammen, kan vægtstængerne 81 betjenes manuelt til indpresning af et koblingselement med indre kanaler, der skaber forbindelser mellem enderne, på højkant ind i fatningen 30 83, efter at fatningen delvis er fyldt med et sejt flydende indlejringsmateriale. Efter indlejringen af et koblingselement,kan den første del 84 således efterlades rundt om koblingselement, og den anden del 85 fjernes for genanvendelse som et værktøj til at optage nye første dele og indkapsle 35 yderligere koblingselementer„5 and 6, the capsule assembly 60 showed that it contains a pair of weights 81 for pressing a coupling member into a socket 83, the weights 81 being adapted to engage the coupling member at its longest edges. A first portion 84 of the capsule assembly 80 forming the socket 83 may be separated from a second portion 85 containing the weights 81 and outer walls for centering and supporting the first portion 84. When these parts 84 and 85 are assembled, the weights 81 is operated manually for pressing a coupling element with internal channels which makes connections between the ends, high in the socket 30 83, after the socket is partially filled with a cool liquid embedding material. Thus, after embedding a coupling element, the first portion 84 can be left around the coupling element and the second portion 85 removed for reuse as a tool for accommodating new first parts and encapsulating 35 additional coupling elements.
