Opfindelsen angår en endeforgreningsdåse af den i kravets indledning angivne art.The invention relates to an end branch box of the kind specified in the preamble of the claim.

Det er opfindelsens formål at anvise udformningen af en endeforgreningsdåse af den i kravets indled-5 ning angivne art, hvor den nødvendige tætning mellem på den ene side bæreorganet og på den anden side dels kappen, dels abonnentledningerne, med henblik på en fluidumtæt isolering af det inden i den aftagelige kappe beliggende rum for abonnenttilslutninger fra omgivel-10 serne, er opnået ved hjælp af enkle midler og på en særdeles hensigtsmæssig måde.SUMMARY OF THE INVENTION It is an object of the invention to provide the design of an end-branch box of the kind set forth in the preamble of the claim, where the necessary sealing between the carrier and on the one hand, the sheath and the subscriber lines, for a fluid-tight insulation of the within the detachable sheath space for subscriber connections from the surroundings is obtained by simple means and in a very convenient manner.

Det angivne formål opnås ved en endeforgreningsdåse, der ifølge opfindelsen er ejendommelig ved den i kravets kendetegnende del angivne udformning.The stated object is achieved by an end branch box which according to the invention is peculiar to the design according to the characterizing part of the claim.

15 Herved opnås ved hjælp af ét enkelt tætningsorgan for det første en automatisk selvlukkende tætning mellem de enkelte abonnentledninger og bæreorganet, idet disse ved indføringen gennem det fælles tætningsorgan åbner slidserne i den ene pakning og kommer til tætnende anlæg 20 imod de i den anden pakning udformede åbninger, og dersom en abonnentledning eventuelt fjernes på et senere tidspunkt, vil de modstående sider af slidserne igen komme i berøring med hinanden og lukke åbningen. For det andet opnås en permanent-elastisk tætning mellem kappen og bæ~ 25 reorganet, idet den tætningslæbe, som fra den ene pakning rager ud fra bæreorganet, indgriber tætnende med kappen under påvirkning af sin iboende elastiske kraft.Hereby, by means of one single sealing means, first, an automatic self-closing seal between the individual subscriber lines and the carrier is obtained, which, when inserting through the common sealing means, opens the slots in one pack and arrives at sealing systems 20 against those formed in the other pack. openings, and if a subscriber line is removed at a later date, the opposite sides of the slots will again contact each other and close the opening. Second, a permanent-elastic seal is obtained between the sheath and the support member, the sealing lip projecting from the one package from the support member sealingly engaging the sheath under the influence of its inherent elastic force.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken 30 fig. 1 viser et vandret snit gennem en endefor greningsdåse ifølge opfindelsen, fig. 2 et lodret snit gennem den i fig. 1 viste endeforgreningsdåse, og fig. 3 et lodret snit i endeforgreningsdåsen i-35 følge fig. 1 set fra siden.The invention will now be explained in more detail with reference to the drawing, in which 1 shows a horizontal section through an end branch of the invention; FIG. 2 is a vertical section through the embodiment of FIG. 1, and FIG. 3 shows a vertical section in the end branch box according to FIG. 1 seen from the side.

I fig. 1 ses abonnentledningstilslutningsklemmerne 1 over kabelafslutningsrummet 13's lukkedæksel 2. Rummet over lukkedækslet anvendes til ledningstilføringen 3, fig. 2.In FIG. 1, the subscriber line connection terminals 1 are shown above the cable cover space 13 of the closure compartment 2. The space above the closure cover is used for the wiring 3, FIG. 2nd

Tætningen af abonnentledningsindføringsåbningerne 5 4 sker ved hjælp af to permanent-elastiske formdele 5 og 6, fig. 3, hvor den ene formdel 6 er udformet med boringer 6a til ledningstætningen, og den anden formdel 5 er udformet med slidser 5a. Slidserne 5a er så lange, at abonnentledningen uden vanskelighed kan føres igennem. Når led-10 ningsgennemføringsåbningen 4 ikke benyttes, ligger slid sen 5a's to sider tæt imod hinanden. Begge elastiske formdele 6,5 har med henblik på lejringssikring udformede forstærkninger henholdsvis 7 og 8, der griber ind i tilsvarende fordybninger i bæreorganet 19's dele. Den ene af 15 formdelene 5 når med en ved kanten rundtgående læbe 9 ud over bæreorganet 19 og tjener derved som elastisk tætningsorgan over for formstofdækslet 32.The sealing of the subscriber line insertion openings 5 4 is effected by means of two permanently elastic mold portions 5 and 6. 3, where one mold portion 6 is formed with bores 6a for the conduit seal and the other mold portion 5 is formed with slots 5a. The slots 5a are so long that the subscriber line can easily pass through. When the lead-through opening 4 is not used, the two sides of the tendon 5a lie close to each other. Both elastic mold members 6.5 have reinforcements 7 and 8 formed for bearing protection, respectively, which engage corresponding recesses in the parts of the carrier 19. One of the 15 mold members 5 reaches a lip 9 extending around the edge beyond the support member 19, thereby serving as an elastic sealing member against the plastic cover 32.

Forbindelsesstykkerne 10 mellem kabeltilslutningsklemmerne 11 og abonnenttilslutningsklemmerne 1 er 20 ført mellem de to dele af en todelt, permanent- -elastisk pakning 12 og 12a, fig. 1 og 3. Begge dele, der har form som en ramme, tjener samtidig som tætning for lukkedækslet 2 mellem abonnentledningsrummet 33 og kabel-afslutningsrummet 13. Den nedre rammedel har noter til 25 forbindelsesstykkerne 10. Noterne er udformet lidt i understørrelse, så at hvert forbindelsesstykke 10 omsluttes tæt ved hjælp af lukkedækslet 2's anlægstryk over pakningsdelen 12a. Fastholdelse af forbindelsesstykkerne 10 opnås ved indgreb med fremspring 14 og 14a, der er udformet i 30 bæreorganet 19.The connecting pieces 10 between the cable connection terminals 11 and the subscriber connection terminals 1 are passed between the two parts of a two-part, permanently-elastic gasket 12 and 12a. 1 and 3. Both parts having the shape of a frame simultaneously serve as a seal for the closure cover 2 between the subscriber wiring space 33 and the cable terminating space 13. The lower frame portion has grooves for the connecting pieces 10. The notes are slightly shaped in size so that each connector 10 is tightly enclosed by the abutment pressure of the closure cover 2 over the gasket member 12a. Retaining of the connectors 10 is achieved by engagement with projections 14 and 14a formed in the support member 19.

Abonnentledningsjordingen opnås ved, at et til hver ledningsindføringsåbning 4 hørende kontaktstykke 15 ved hjælp af en skrue 16, som det er fjedrende anbragt på, føres til ledningsjorden. Samtidig holdes skruerne 16 fast ved 35 hjælp af kontaktstykket 15. Både skruerne og kontaktstyk- 3 14531 9The subscriber line grounding is achieved by inserting a contact piece 15 associated with each lead insertion opening 4 by means of a screw 16 on which it is resiliently mounted. At the same time, the screws 16 are held in place by means of the contact piece 15. Both the screws and the contact piece

kerne bæres af en såkaldt kappeforbinder 17, der er U-for-met og er anbragt således, at kontaktstykkerne 15, der er ført i bæreorganet 19's noter 18, ikke kan komme ud af noterne. Kappeforbinderindretningen 20 med skruerne 16 og 5 kontaktstykkerne 15 sørger samtidig for en god lejrings sikring af abonnentledningerne ved træk-, tryk- og torsionspåvirkninger og har ved sin ene side en klemme 21 til tilslutning af en jordtråd.the core is supported by a so-called jacket connector 17 which is U-shaped and is arranged so that the contact pieces 15 inserted in the notes 18 of the support member 19 cannot come out of the notes. At the same time, the cap connecting device 20 with the screws 16 and 5 connectors 15 provides a good bearing securing of the subscriber wires by tensile, pressure and torsional influences and has at one side a terminal 21 for connecting a ground wire.

Lejringssikringen og kontakteringen af jordkablet 10 opnås på grund af den stadig større anvendelse af lagkappe-kabler ved hjælp af en indretning bestående af en formstof-ring 22, et spændebånd 23 og to kontaktplader 24 og 25, på hver af hvilke der er udformet to sideflige 26 og 27, ved hjælp af hvilke indretningen fastholdes i bæreorganet 19 15 og forbindelsen til jordledningen tilvejebringes.The locking and contacting of the ground cable 10 is achieved by the increasing use of layer sheath cables by means of a device consisting of a plastic ring 22, a clamping band 23 and two contact plates 24 and 25, on which two side tabs are formed. 26 and 27, by means of which the device is held in the support member 19 15 and the connection to the ground wire is provided.

Beliggenheden af de ved enden af de tilsvarende forlængede forbindelsesstykker 10 siddende knivkontakter 28 til de indstikkelige overspændingsaflederkassetter er i forbindelse med på bæreorganet 19 udformede ribber 29 og 20 30 hensigtsmæssigt udformet således, at indstikningen af kassetterne kun kan ske i én retning.The location of the knife contacts 28 at the end of the correspondingly extended connecting pieces 10 to the insertable surge arrester cartridges is suitably formed in connection with the ribs 29 and 20 30 of the support member 19, so that the insertion of the cartridges can only take place in one direction.

Endeforgreningsdåsens formstofbæreorgan 19 er udformet, således at det - trods sin noget større dimensionering - kan monteres på konsollet 31 tilhørende en tid-25 ligere kendt endeforgreningsdåse.The plastic manifold 19 of the end branch box 19 is designed so that, despite its somewhat larger dimension, it can be mounted on the bracket 31 of a previously known end branch box.
