Den foreliggende opfindelse angâr et stikkontaktag-gregat til forbindelse af et kabel med en stremskinne og af den i krav 1's indledning angivne art.The present invention relates to a power supply assembly for connecting a cable with a power strip and of the kind set forth in the preamble of claim 1.

Ved et kendt kabelfordelerskab (DE-PS 31 35 772) er 5 det nedefra indferte kabel via en fjederkontakt forbundet med den ene knivkontakt i en med lodret længdeakse under en stremskinne anbragt NH-sikring, hvis anden knivkontakt er forbundet med stremskinnen over et vinkelstik, som ved den mod sikringen vendte ende har en dennes knivkontakt 10 optagende fjederkontakt, og hvis anden ende udviser en stikstift, som kan indferes i et hul i stremskinnen.In a known cable distributor (DE-PS 31 35 772), the bottom-inferred cable is connected via a spring contact to one knife contact in a vertical longitudinal axis below a power rail, the other knife contact of which is connected to the power rail over an angle plug, which at the end facing the fuse has a spring contact of its knife contact 10 and whose other end has a pin which can be inserted into a hole in the guide rail.

Allerede fordi dette kabelfordelerskabs kontaktaggregat er helt uden bereringsbeskyttelse, kan det ikke anvendes til netadskillelse eller til kobling -under belastning. Der er 15 heller ingen mulighed for at fiksere vinkelstikket i en sâdan stilling i skabet, at det ikke star i forbindelse med stremskinnen.Even though this cable distributor's contact unit is completely without contact protection, it cannot be used for mains separation or for coupling-under load. Also, there is no possibility of fixing the angular plug in such a position in the cabinet that it does not interfere with the power strip.

Der kendes et stikkontaktaggregat (DE-GM 82 36 316), som pâ grund af bereringssikker afdækning af sâvel det en 20 stremskinne tilordnede kontaktstykke som stikkets kontakt-elementer i og for sig skulle være egnet til at skille stremvejen mellem stremskinne og kabel, da stikket kan be-tjenes uden risiko, hvis adskillelsen sker stremlest. Der forekommer dog nogle problemer. Trækkes stikket nemlig 25 helt ud, ma der drages omsorg for, at det fastholdes i den adskillende stilling og sikrer mod utilsigtet genindkob-ling. En fiksering af stikket i skillestillingen er ved det kendte aggregat kun muligt derved, at man ved adskil-lelse af str0mvejen kun trækker det sâ langt ud, at kon-30 taktstykkernes berering ophæves, medens den de fingerlig- nende kontaktelementer afdækkende beskyttelseshusdel dog stadig er mekanisk fikseret i stikbesningen. Herved er selv en mindre kraftpâvirkning, eksempelvis et utilsigtet sted mod stikket, tilstrækkeligt til atter at trykke stik-35 ket sâ langt ind i besningen, at der etableres kontakt mellem kontaktstykkerne. Der er sâledes ingen beskyttelse mod utilsigtet genindkobling.A socket assembly (DE-GM 82 36 316) is known which, due to contact-safe coverage of both the 20 contact strip assigned as the contact elements of the plug, should be suitable for separating the path between the cable rail and the cable as the plug can be operated without risk if the separation is difficult. However, some problems do occur. If the plug is pulled out fully 25, care must be taken to keep it in the separating position and to prevent accidental reconnection. Fixing of the plug in the separating position is only possible in the known assembly in that by separating the current path it only extends so far that the contact of the contact pieces is lifted, while the protective housing covering the finger-like contact elements is still mechanically fixed in the connector. In this way, even a minor force effect, for example an unintended location against the plug, is sufficient to push the plug again so far into the bush as to establish contact between the contacts. Thus, there is no protection against accidental reconnection.

Formâlet med den foreliggende opfindelse er at anvise et stikkontaktaggregat af.den omhandlede art, som ikke blot er egnet til brug i et meget fladt kabelfordelerskab, men som ogsâ gor det muligt, nâr stikket er bragt til en 5 stilling, hvor forbindelse mellem kontaktstykkerne er op-hævet, da pâ enkel og bekvem mâde at fastholde det pâ en sâdan mâde, at det er sikret mod utilsigtet genindkobling.The object of the present invention is to provide an outlet of the kind in question, which is not only suitable for use in a very flat cable distributor, but also possible when the plug is brought to a position where connection between the connectors is canceled, since in a simple and convenient way to maintain it in such a way that it is secured against accidental reconnection.

Dette opnâs ifolge opfindelsen ved den i krav 1 anvi-ste udformning.This is achieved according to the invention in the embodiment of claim 1.

10 Nâr stikket er udtaget af den forste udskæring, er det pâ simpel mâde muligt at sikre det mekanisk ved at indsætte det i den anden udskæring. Da forbindelse mellem kontaktstykkerne er udelukket, nâr stikket er anbragt i den anden udskæring, er utilsigtet indkobling forhindret, 15 fordi indkobling forudsætter, at stikket udtages fra den anden udskæring og genindsættes i den ferste udskæring.10 When the plug is removed from the first cut, it is simple to secure it mechanically by inserting it into the second cut. Since connection between the connectors is ruled out when the plug is placed in the second cut, unintentional switching on is prevented, because switching on requires that the plug is removed from the second cut and reinserted in the first cut.

Til genindkobling kræves altsâ flere enkeltforanstaltnin-ger, hvor stikket bevæges i forskellige retninger, og det kan derfor ikke ske ved en tilfældig, utilsigtet pâvirk-20 ning af stikket, som det er tilfældet ved kendte aggrega- ter.For reconnection, therefore, several single measures are required in which the plug is moved in different directions, and this cannot therefore be done by a random, unintended actuation of the plug, as is the case with known aggregates.

Den anden udskæring kan være anbragt over, ved siden af eller under den ferste udskæring. En særlig omfattende beroringsbeskyttelse opnâs ved den i krav 3 anviste ud-25 formning, hvor stikkets beskyttelseshus, nâr stikket er anbragt i den anden udskæring ved siden af den forste udskæring, dækker for adgang til denne.The second cutout may be placed above, adjacent to or below the first cutout. Particularly comprehensive contact protection is obtained by the design according to claim 3, where the plug housing, when the plug is placed in the second cut next to the first cut, covers for access thereto.

Nâr det til stikket ferende kabel er forholdsvis stift, hvilket eksempelvis er tilfældet, nâr den frie 30 kabelende er forholdsvis kort og/eller ved store leder- tværsnit, er det af hensyn til hândteringen af stikket hensigtsmæssigt, at den anden udskæring er anbragt ved siden af den ferste eller, som anvist i krav 5, er udfor-met i et mellemstykke, der kan placeres i den forste ud-35 skæring.When the cable leading to the plug is relatively rigid, as is the case, for example, when the free cable end is relatively short and / or at large conductor cross-sections, it is appropriate for the purpose of handling the plug that the second cut is placed next to it. of the first or, as disclosed in claim 5, is formed in a spacer which can be placed in the first cut.

Det er, som ànvist i krav 6, hensigtsmæssigt, at det den forste udskæring dannende beskyttelseshus er forsynet med en holder for mellemstykket. Nâr dette ikke er i funk- - 3 -As indicated in claim 6, it is expedient for the protective housing forming the first cut to be provided with a holder for the intermediate piece.

Holderen for mellemstykket kan hensigtsmæssigt være udformet, sâ det kan anvendes som den anden udskæring.The holder for the spacer may conveniently be designed so that it can be used as the second cut.

5 Herved opnâs en universal udformning, som kan benyttes.5 Hereby a universal design which can be used can be obtained.

med eller uden mellemstykke efter omstændighederne pà brugsstedet.with or without spacer according to the circumstances of the place of use.

Ved den i krav 9 anviste udformning opnâs, at det i udskæringen isatte stik kan fastholdes lesneligt. Det er 10 herved, som anvist i krav 10, hensigtsmæssigt, at stikket kan fastholdes i en stilling, hvor der ikke er kontakt mellem kontaktstykkerne, men hvor en sâdan kontakt hurtigt kan etableres. Nâr dette enskes, indebærer den nævnte udformning af rasteelementerne, at rastemodstanden ferst 15 skal overvindes med en vis trykkraft. Denne trykkraft bevirker, nâr rastemodstanden overvindes, at kontaktetab-leringen sker med stor fart.In the embodiment according to claim 9, it is achieved that the plug inserted in the cut-out can be legibly retained. It is convenient here, as stated in claim 10, that the plug can be held in a position where there is no contact between the connectors, but where such contact can be established quickly. When this is agreed upon, the said design of the resting elements implies that the resting resistance must be overcome with some compressive force. This compressive force, when the resistance of the ridge is overcome, causes the contact establishment to take place at great speed.

Ved yderligere at udforme aggregatet som anvist i krav 11 opnâs, at der, ogsâ nâr kontakten skal brydes, mâ 20 udeves en kraft, der overvinder en rastemodstand. Bryd-ning af kontakten sker altsâ hurtigt, sâledes at det er muligt at foretage afbrydelse af forholdsvis heje belast-ninger, idet den ved brydning dannede lysbue slukkes hurtigt.By further designing the assembly as described in claim 11, it is achieved that, even when the contact is to be broken, 20 must be exerted a force which overcomes a break resistance. Breaking of the contact is thus done quickly, so that it is possible to interrupt relatively high loads, since the arc formed during breaking breaks off quickly.

The zero conductor rail is permanently conductively connected to a Cables 9, 10 and 11 cables 9, 10 and 11 lower down from the bottom of the cable distributor 1 are also separately connected to each of the current rails via separate terminals 12, 13 and 14 respectively. , 5 and 6, respectively.

20 Stikkontaktaggregaterne 12-14 samt yderligere, i fig. 1 ikke viste aggregater for andre, heller ikke viste kabler, er identiske, hvorfor kun aggregaget 14 for kablet 11 vil blive nærmere omtalt i forbindelse med fig. 2-8.20 The sockets 12-14 and further, in FIG. 1, the assemblies not shown for other cables, not shown, are identical, so only the assembly 14 for the cable 11 will be discussed in more detail in connection with FIG. 2-8.

Stikkontaktaggregatet 14 omfatter et sâvel til ad-25 skillelse som til kobling under belastning egnet stik 16 med et beskyttelseshus 17, som ber0ringssikkert dækker et kontaktstykke 18, som er elektrisk ledende forbundet med kablets 11 leder. Herved forlober den inde i beskyttel-seshuset 17 dannede kabeloptagningskanal for kablet 11 vin-30 kelret pâ den bosningformede beskyttelseshusdel 31, som dæk ker kontaktstykket 18. Stikket 16 er altsâ et vinkelstik. Denne udformning muliggor sammen med de udformningsmæssige-detaljer, som skal omtales i det f0lgende, at stikkontaktaggregatet i den vinkelret pâ kabeloptagningskanalen stâ-35 ende retning kun stiller ganske ringe pladskrav. Stikkon taktaggregatet er sâledes meget fladt og kan anbringes i et kabelfordelerskab med ringe dybde som vist med fuldThe socket assembly 14 comprises a separator as well as a suitable connector 16 under load, with a protective housing 17, which touchingly covers a connector 18 electrically conductively connected to the conductor of the cable 11. Hereby, the cable receiving channel formed within the protective housing 17 for the cable 11 extends perpendicular to the bush-shaped protective housing portion 31 which covers the contact piece 18. The plug 16 is thus an angular plug. This configuration together with the design details to be discussed below makes it possible for the socket assembly in the direction perpendicular to the cable receiving channel to place only very low space requirements. The Stikkon clock unit is thus very flat and can be placed in a cable distributor with low depth as shown with full

Den str0mskinnen 6 tilordnede del af aggregatet 14 omfatter et beskyttelseshus 19, som beraringssikkert dæk-5 ker et med stromskinnen 6 elektrisk ledende kontaktstykke 20 (fig. 4 og 6). I ét med beskyttelseshuset 19 er pâ begge sider af dette udformet ansatse 22,af hvilke kun den eue kan ses i fig. 2 og 8. Ansatsene 22 tjener til at dække dele af stromskinnen 6 og har herfor bagud âben 10 C-profil med holdenæser 23 langs kanteme. Nâr beskyttelseshuset 19 med ansatsene 22 trykkes mod stramskinnen 6, vil næserne 23 med snapvirkning gribe bag om stramskinnen. Sâvel beskyttelseshuset 17 for stikket 16 som huset 19 er fremstillet af til isolerende huse sædvanligt anvendt 15 plastmateriale, som tillader elastisk deformering af ansatsene 22 ved næserne 23. Skal der pâ samme stromskinne 6 anbringes flere stikkontaktaggregater tæt ved siden af hinanden, kan ansatsene 22 afkortes eller fjernes helt.The portion of the power rail 6 assigned to the assembly 14 comprises a protective housing 19 which covers non-contactably an electrically conductive contact piece 20 with the current rail 6 (Figures 4 and 6). Along with the protective housing 19, on both sides of this housing are formed 22, of which only the eue can be seen in FIG. 2 and 8. The guides 22 serve to cover portions of the busbar 6 and have rearwardly open 10 C profile with holding nozzles 23 along the edges. When the protective housing 19 with the lugs 22 is pressed against the tension rail 6, the noses 23 will snap behind the tension rail with snap action. Both the protective housing 17 for the plug 16, which the housing 19 is made of insulating casing commonly used 15 plastic material, which allows elastic deformation of the lugs 22 at the noses 23. If several plugs are to be placed on the same busbar 6, the lugs 22 can be shortened. or removed completely.

Til centrering og til sikring af beskyttelseshuset 19 mod 20 forskydning pâ langs ad str0mskinnen 6 har huset 19 pâ in-dersiden en fremspringende kappe 25, som griber om hovedet pâ en skrue 26, med hvilken kontaktstykket 20 er fastskruet til str0mskinnen 6 (fig. 4, 6 og 7).For centering and securing the protective housing 19 against 20 longitudinal displacement along the current rail 6, the housing 19 on the inside has a protruding sheath 25 which engages the head of a screw 26 with which the contact piece 20 is screwed to the current rail 6 (Fig. 4 , 6 and 7).

Som det fremgâr af fig. 3, 5 og 8, har stikkets 16 i 25 beskyttelseshuset 17 anbragte kontaktstykke 18, som er elektrisk ledende forbundet med kablets 11 leder, to fin-gerlignende kontaktelementer 28, som med en mellemliggende slids 29 strækker sig vinkelret pâ den kabeloptagnings-kanalen indeholdende hoveddel af beskyttelseshuset 17 og 30 inde i den kontaktelementerne 28 afdækkende, bosningsfor- mede beskyttelseshusdel 31. Slidsen 29 er beregnet til optagelse af et knivkontaktelement 33, som udg0res af det kontaktdannende endeomrâde af det med stromskinnen 6 for-bundne kontaktstykke 20. For knivkontaktelementets 33 35 indgriben i den kontaktelementerne 28 dækkende beskyttel seshusdel 31 har denne udskæringer 34.

The slot 29 is intended to receive a knife contact element 33 formed by the contact-forming end area of the contact piece 20 connected to the current rail 6 for the knife contact element 33 35. the engagement of the protective housing housing portion 31 covering the contact members 28 has these cuts 34.

5 Ved knivkontaktelementet 35 er beskyttelseshuset 19 sâledes udformet, at det danner en stikb0sningslignende udskæring 41, i hvilken stikkets 16 beskyttelseshusdel 31 kan indfores for at lade knivkontaktelementet 33 indtræde i slidsen 29 mellem stikkets kontaktelementer 28 og be-10 virke kontakt mellem kontaktstykkerne 20 og 18. Som det fremgâr af fig. 3 og 5-8 danner beskyttelseshuset 19 ved udskæringen 41 en den evre indforingsâbning for husdelen 31 dækkende liste 42, som strækker sig pâ langs ad knivkontaktelementet 33 og hindrer manuel berering af dette.5 At the knife contact element 35, the protective housing 19 is designed to form a socket-like cut 41 in which the protective housing part 31 of the plug 16 can be inserted to allow the knife contact element 33 to enter into the slot 29 between the contact elements 28 and the contact 20 between the contacts 18. As can be seen from FIG. 3 and 5-8, the cut-out housing 19 at the cut-out 41 forms an even insertion opening for the housing part 31 covering the groove 42 which extends along the knife contact element 33 and prevents manual contact thereof.

15 Som det tydeligst fremgâr af fig. 2, er udskæringens 41 sidevægge foroven opslidsede, sâledes at der dannes op-ad fremstâende, fjedereftergivelige holdetunger 44. Disse har pâ indersiden rastefordybninger 45, i hvilke et mod-svarende rastefremspring 46 pâ ydersiden af beskyttelses-20 husdelen 31 aftageligt kan indsnappe, nâr stikket 16 med sin husdel 31 indfores helt i udskæringen 41 som vist i fig. 2 og 3, hvor stikkontaktaggregatet befinder sig i indkoblende stilling, hvor knivkontaktelementet 33 danner kontakt med de fingerlignende kontaktelementer 28. Ud over 25 rastefremspringene 46 har husdelen 31 et par yderligere rastefremspring 47, som kan samvirke med rastefordybningeme 45, nâr beskyttelseshusdelen 31 ikke er fort helt ind i udskæringeme 41 ( se fig. 4 og 5 ), hvorved knivkontaktelementet 33 er uden beroring med kontaktelementeme 28.15 As can be seen most clearly in FIG. 2, the sidewalls of the cut 41 are slit at the top so as to form upwardly projecting spring-retaining retaining tongs 44. These have on the inside ridge recesses 45 in which a corresponding ridge projection 46 on the outside of the protective housing part 31 can be removably snap the plug 16 with its housing part 31 is fully inserted into the cutout 41 as shown in FIG. 2 and 3, where the socket assembly is in the engaging position where the knife contact element 33 contacts the finger-like contact elements 28. In addition to the 25 protrusions 46, the housing portion 31 has a pair of additional protrusions 47 which can cooperate with the protuberances 45 when the protective housing portion 31 is not all the way into the cutouts 41 (see Figures 4 and 5), whereby the knife contact element 33 is without contact with the contact elements 28.

30 Kontakt sluttes eller brydes, ved at der mod husdelen 31 udeves en kraft, der er tilstrækkelig til at overvinde snapvirkningen mellem rastefordybningeme 45 og rastefremspringene 47 henholdsvis 46.Contact is closed or broken by exerting a force sufficient on the housing portion 31 to overcome the snap action between the screen recesses 45 and the screen protrusions 47 and 46, respectively.

Ogsâ fra den i fig. 2 og 3 .viste indkoblende stilling mâ der 5 f0rst overvindes en rastemodstand mellem forbybningerne 45 og fremspringene 46, inden husdelen 31 kan trækkes ud- ad. Nâr denne rastemodstand overvindes, sker der en meget hurtig udkoblingsbevægeise. Khivkontaktelementet 33 og kontaktelementerne 28 fores meget hurtigt fra hinanden, 10 sâledes at den ved udkobling under belastning opstâede lysbue atter slukkes hurtigt.- 7 - overcoming the break resistance. Due to the necessary operating force, as soon as the resistance is overcome, a very fast switching movement will occur. Also from the one shown in FIG. 2 and 3, the switching position shown 5 must first overcome a resting resistance between the forks 45 and the projections 46 before the housing part 31 can be pulled out. When this break resistance is overcome, a very fast switch-off movement occurs. The kiv contact element 33 and contact elements 28 are moved very quickly apart, 10 so that the arc arising during switching off is quickly extinguished.

Som det især fremgâr af fig. 4, 6 og 7, har beskyt-telseshuset 19 ved stromskinnen 6 en yderligere udskæring 51 ved siden af udskæringen 41 og, i modsætning til denne, 15 uden kontaktelementer, som kunne komme i beroring med de fingerlignende kontaktelementer 28, nâr husdelen 31 an-bringes i den yderligere udskæring 51. Til samvirke med rastefremspringene pâ husdelen 31 har ogsâ den yderligere udskæring 51 rastefordybninger 55. Indsat i den yderli-20 gere udskæring 51 er stikket 16 sikret mod utilsigtet ind- kobling.As can be seen in particular from FIG. 4, 6 and 7, the protective housing 19 at the flow rail 6 has a further cut 51 next to the cut 41 and, in contrast, 15 without contact elements which could come into contact with the finger-like contact elements 28 when the housing part 31 is inserted into the additional cut 51. In cooperation with the protrusions on the housing part 31, the additional cut 51 also has recesses 55. Inserted in the additional cut 51, the plug 16 is secured against unintentional engagement.

Hvis kablet 11 med stikket 16 udgor en forholdsvis stiv enhed, eksempelvis hvis stikket er anbragt pâ en kort kabelende og/eller pâ et kabel med stort ledertværsnit, 25 kan det være vanskeligt at flytte stikket mellem de to ud- skæringer 41 og 51. I sa tilfælde kan man, som vist i fig.If the cable 11 with the plug 16 forms a relatively rigid unit, for example if the plug is arranged on a short cable end and / or on a cable with a large conductor cross-section 25, it may be difficult to move the plug between the two cut-outs 41 and 51. In such cases, as shown in FIG.

7 og 8, anvende et mellemstykke 61, som i den ene ende er udformet sâledes, at det kan indfores i udskæringen 41 pâ samme mâde som husdelen 31, og i den anden ende er udfor-30 met sâledes, at det kan optage husdelen 31 pâ samme mâde som udskæringen 41. Nâr mellemstykket 61 er indsat mellem udskæringen 41 og husdelen 31, er der ingen mulighed for kontakt mellem knivkontaktelementet 33 og de fingerlignende kontaktelementer 28. Nâr mellemstykket 61 ikke benyttes 35 til at hindre indkobling, kan det anbringes i den yderli gere udskæring 51.7 and 8, use an intermediate piece 61 formed at one end such that it can be inserted into the cutout 41 in the same manner as the housing part 31, and at the other end is designed to accommodate the housing part 31 In the same way as the cutout 41. When the intermediate piece 61 is inserted between the cutout 41 and the housing part 31, there is no possibility of contact between the knife contact element 33 and the finger-like contact elements 28. When the intermediate piece 61 is not used 35 to prevent engagement, it can be placed in it. further cutting 51.

- 8 - I stedet for en yderligere i kablets 11 længderetning forsatte udskæring 51 eller et mellemstykke 61 kan man til fastholdelse i udkoblende stilling af stikket pâ en for-holdsvis stiv kabelende benytte en udskæring 51' som vist 5 i fig. 5. Denne udskæring 51' er anbragt ved siden af ud-skæringen 41, sâledes at det ikke kræver nogen særlig be-vægelse af stikket 16 i kablets 11 længderetning at flytte stikket fra den ene udskæring til den anden.- 8 - Instead of a further cut 51 or an intermediate piece 61 provided in the longitudinal direction of the cable 11, a cut-out 51 'as shown 5 in FIG. 5. This cutout 51 'is arranged adjacent to the cutout 41 so that it does not require any particular movement of the plug 16 in the longitudinal direction of the cable 11 to move the plug from one cutout to the other.

Som det fremgâr af fig. 4, er indforing af stikkets 10 husdel 31 i udskæringen 41, takket være en forreste affas-ning 76 pâ husdelen 31 og den ringe længde af de indf0-ringsâbningen begrænsende vægdele 75, ogsâ mulig, selv om husdelens 31 længdeakse skrâner noget i forhold til udskæringen 41. For yderligere at lette indforingen under 15 disse forhold kan den 0vre kant af udskæringen være tragt-formet.As can be seen from FIG. 4, the insertion of the housing part 31 of the plug 10 into the cut-out 41, thanks to a front bevel 76 on the housing part 31 and the small length of the wall portions 75 restricting the insertion opening, is also possible, although the longitudinal axis of the housing part 31 slopes somewhat in relation to the cutout 41. To further facilitate the insertion under these conditions, the upper edge of the cutout may be funnel-shaped.
