Opfindelsen angår en kabelgennemføringsenhed i et hus til elektriske apparater, som er tætnet ved hjælp af en gummiring, som ligger i et kammer i huset dannet af to pa-5 rallelle vægge, og hvor gummiringens cylindriske overflade omgives af et elastisk spændehånd, som kan strammes ved hjælp af et skruearrangement, således at gummiringen ved stramning af skruearrangementet presses koncentrisk mod kablet samt med sine plane flader presses mod kammervæggenes 10 over for hinanden liggende inderflader.The invention relates to a cable gland unit in a housing for electrical appliances, which is sealed by means of a rubber ring, which is located in a chamber in the housing formed by two parallel walls, and where the cylindrical surface of the rubber ring is surrounded by an elastic clamping hand which can be tightened by means of a screw arrangement, so that by tightening the screw arrangement, the rubber ring is pressed concentrically against the cable and with its flat surfaces is pressed against the inner surfaces of the chamber walls 10.

En sådan kabelgennemføringsenhed kendes fra tysk patentskrift nr. 641.366.Such a cable gland unit is known from German Patent Specification No. 641,366.

Formålet med opfindelsen er at muliggøre, at en kabelgennemføringsenhed, som passer til et af en isolationskappe 15 omsluttet kabel med et antal isolerede ledere, også kan anvendes til gennemføring af alene lederne med deres isolation.The object of the invention is to enable that a cable bushing unit which fits a cable enclosed by an insulating sheath 15 with a number of insulated conductors can also be used for conducting the conductors alone with their insulation.

En passende udfyldende pakning i gummiringens lysning frembyder sig som en mulighed. P.eks, kendes der fra tysk patentskrift nr. 828.269 en rørdåse med en udfyldende pakning med 20 et antal huller, hvor der ved rørdåselågets påskruning opnås en vis klemvirkning på de ledere, som føres gennem hullerne, men der opnås ikke altid et helt tilfredsstillende tætnende og tilfredsstillende aflastende anlæg af en sådan pakning med lederne, og de ubenyttede huller i den udfyldende pakning 25 kan også give tæthedsproblemer. Det har ifølge opfindelsen vist sig, at det efterstræbte tilfredsstillende aflastende anlæg og en upåklagelig tæthed opnås ved, - at der i gummiringens lysning er anbragt en indsatspakning med huller med blændstifter, 30 _ og at gummiringen har en rundtgående not med trapezformet tværsnit, og at spændbåndet har et tilsvarende trapezformet tværsnit.A suitable filling gasket in the clearance of the rubber ring presents itself as an option. For example, German Patent Specification No. 828,269 discloses a pipe box with a filling gasket with a number of holes, where by screwing on the pipe box lid a certain clamping effect is obtained on the conductors which are passed through the holes, but a completely satisfactory sealing and satisfactory relief facilities of such a gasket with the conductors, and the unused holes in the filling gasket 25 can also cause leakage problems. According to the invention, it has been found that the desired satisfactory relieving abutment and an impeccable tightness are obtained by - - in the opening of the rubber ring an insert gasket with holes with glare pins, 30 - and that the rubber ring has a circumferential groove with a trapezoidal cross-section, and that the strap has a corresponding trapezoidal cross-section.

Det vil ses, at konstruktionen ifølge opfindelsen giver en særdeles god spændvirkning i radial retning til op-35 nåelse af tætning om og aflastning af lederne og en meget effektiv ekspansion i aksial retning til tætning mod kammervæggene .It will be seen that the construction according to the invention provides a very good clamping effect in radial direction to achieve sealing about and relief of the conductors and a very effective expansion in axial direction for sealing against the chamber walls.

Ifølge opfindelsen har det vist sig at være særlig 150430 2 fordelagtigt, at spændbåndets tværsnit er afrundet på den indvendige flade. Herved opnår spændbåndet en bedre aksial ekspansion og en bedre radial sammentrængning, end når den pågældende flade på spændbåndet er plan og har uafrundede 5 kanter.According to the invention, it has proved to be particularly advantageous that the cross-section of the clamping band is rounded on the inner surface. Hereby the tension band achieves a better axial expansion and a better radial contraction than when the surface in question on the tension band is flat and has unrounded 5 edges.

Opfindelsen skal forklares nærmere i forbindelse med tegningen, hvor fig. 1-3 viser en kendt kabelgennemføringsenhed ifølge tysk patentskrift 641.366 i henholdsvis sidebille -10 de, planbillede og tværsnit, fig, 4 viser en udførelsesform for den ifølge opfindelsen anviste indsatspakning omgivet af en tilhørende gummiring, fig, 5 samme dele omgivet af et spændbånd, 15 fig, 6 de tre nævnte komponenter i tværsnit, og fig. 7 en installationsdåse.The invention will be explained in more detail in connection with the drawing, in which fig. 1-3 show a known cable bushing unit according to German patent specification 641,366 in side view -10, plan view and cross section, respectively, fig. 4 shows an embodiment of the insert package according to the invention surrounded by an associated rubber ring, fig. 5 the same parts surrounded by a clamp, Fig. 15 shows the three mentioned components in cross section, and 7 an installation box.

I fig. 1-3 vil det ses, at der i et kammer a mellem parallelle vægge b og c (se også fig .7) ligger en tætningsgummiring d. Et elastisk spændbånd e kan indsnævres ved 20 hjælp af en skrue f med møtrik g, hvorved gummiringen d med sin indre cylindriske flade h presses mod ledningen og med sine to endeflader i og k presser mod kammerets a vægge b og c og således tætner apparathusets inderrum i alle retninger. Fig. 3 viser, at spændbåndet e er noget smallere end 25 gummiringen.In FIG. 1-3 it will be seen that in a chamber a between parallel walls b and c (see also fig. 7) there is a sealing rubber ring d. An elastic clamping band e can be narrowed by means of a screw f with nut g, whereby the rubber ring d with its inner cylindrical surface h is pressed against the wire and with its two end faces i and k presses against the walls b and c of the chamber a and thus seals the inner space of the apparatus housing in all directions. FIG. 3 shows that the strap e is somewhat narrower than the rubber ring.

Den i fig. 4-6 viste udførelsesform for kabelgennemføringsenheden ifølge opfindelsen omfatter en gummiring D og et spændbånd E med gevind skærende skrue F og overlappende flige, som sikrer spændbåndets kontinuerlige omslutning' af 30 gummiringen, også i skruens område. Gummiringen D og spændbåndet E har tværsnit som henholdsvis en kileremskive og en kilerem (trapezformet)hvor spændbåndets E indvendige flade A er afrundet, I gummiringens lysning er der anbragt en indsatsåbning P. I denne er der boret et antal huller: i det viste 35 eksempel 8 huller, som hver især er lukket med en blænd-stift S. De i hinanden indgribende cylindriske flader på gummiringens inderside og på'pakningens yderside kan være 150430 3 forsynet med en rilning E som antydet i fig, 6,The device shown in FIG. 4-6 of the cable bushing unit according to the invention comprises a rubber ring D and a clamping band E with threaded cutting screw F and overlapping tabs, which ensures the continuous enclosing of the rubber ring of the clamping ring, also in the area of the screw. The rubber ring D and the clamping band E have cross-sections as a V-belt pulley and a V-belt (trapezoidal), respectively, where the inner surface A of the clamping band E is rounded. An insert opening P is placed in the clearance of the rubber ring. 8 holes, each of which is closed with a glare pin S. The engaging cylindrical surfaces on the inside of the rubber ring and on the outside of the gasket may be provided with a groove E as indicated in Fig. 6,

Ved "brugen udelades indsatspakningen £ helt, hvis man skal gennemføre et kabel med isolationskappe. Hvis man derimod skal gennemføre de enkelte ledere med disses isola-5 tion, slår man det fornødne antal blændstifter S ud af deres huller og indfører de isolerede ledere, hvorpå man spænder ved hjælp af skruen F,In use, the insert gasket £ is omitted altogether if a cable with insulating sheath is to be carried out. If, on the other hand, the individual conductors are to be provided with their insulation, the required number of glare pins S is knocked out of their holes tighten using the screw F,

Kabelgennemføringsenheden egner sig også til montering af en panserslange, idet kraven på dennes slangenippel 10 N (fig. 7) kan fastklemmes mellem indersiden af den yderste parallelle væg b og gummiringen, således at en fastspænding med møttik kan undværes. Det vil forstås, at åbningen i den yderste parallelle væg b skal være mindre end slangeniplens N" kravediameter, medens hullet i den inderste parallelle væg 15 c skal tillade kravens passage.The cable entry unit is also suitable for mounting an armored hose, as the collar of its hose nipple 10 N (Fig. 7) can be clamped between the inside of the outer parallel wall b and the rubber ring, so that a clamping with a nut can be dispensed with. It will be appreciated that the opening in the outermost parallel wall b must be smaller than the collar diameter of the hose nipple N ", while the hole in the innermost parallel wall 15c must allow the passage of the collar.
