Opfindelsen angår en håndbetjent sikringsafbryder ifølge den indledende del af krav 1. Sådanne sikringsafbrydere virker blokvis opstillet ved siden af hinanden især som lavspændingssikringer i tilknytning til beboelse.The invention relates to a hand operated circuit breaker according to the preamble of claim 1. Such circuit breakers act blockwise arranged side by side especially as low voltage fuses in connection with housing.

5 Sådanne afbrydere, eksempelvis som de i DE offent liggørelsesskrift 2.934.149 eller DE offentliggørelsesskrift 2.618.360 omtalte, kendte afbrydere, er tilvejebragt med en lågformet afbrydervinge, med hvilken en i huset placeret afbryder håndbetjenes. I afbryderens sluttede stilling dæk-10 kes således det rum, som er tilvejebragt til smeltesikringsindsatsen, af afbrydervingen. I tilknytning til udskiftning af sikringen må afbrydervingen således først stilles i en åben stilling, hvorved smeltesikringsindsatsens kontaktstykke på forsyningssiden ikke har nogen forbindelse med strøm-15 forsyningsnettet. Samtidigt aktiveres en låsemekanisme ved ikke isat eller ikke korrekt isat smeltesikringsindsats, hvilken mekanisme blokerer afbrydervingen i dens åbne stilling. Herved er der for brugeren tilvejebragt en høj grad V.Such switches, such as those known in known disclosure disclosures in DE disclosure specification 2,934,149 or DE disclosure disclosures 2,618,360, are provided with a lid-shaped switch blade with which a switch located in the housing is hand operated. Thus, in the closed position of the switch, the space provided for the melt protection insert is covered by the switch wing. Thus, in connection with the replacement of the fuse, the switching wing must first be placed in an open position, whereby the contact piece of the fuse insert on the supply side has no connection with the power supply network. At the same time, a locking mechanism is activated by not inserted or incorrectly inserted melt protection insert, which blocks the switching lever in its open position. A high degree of V is thus provided for the user.

af berøringssikkerhed.of touch security.

20 Opfindelsen går ud fra den erfaring, at der i prak sis ved en kraftig påvirkning af afbrydervingen kan tilvejebringes en ødelæggelse af låsemekanismen. Herved bliver afbryderen uegnet til at virke, eller i værste fald tilvejebringes en slutning af belastningsafbryderen, hvorved det 25 på forsyningssiden tilvejebragte bundkontaktelement i sikringssøjlen sættes under spænding. Især kan, når en elektrisk forbruger er sikret flere gange ved blokvis ved siden af hinanden opstillede sikringsafbrydere, dele af forbrugeren sættes under spænding over de parallelt beliggende, 30 med korrekt virkende isat smeltesikringsindsats tilvejebragte sikringsafbrydere, selv om der åbenbart foreligger en fejl i forbrugerkredsen.The invention is based on the experience that, in practice, by a strong influence on the switching wing, a destruction of the locking mechanism can be provided. This makes the switch unsuitable for operation or, at worst, provides an end of the load switch, whereby the bottom contact element provided on the supply side is energized. In particular, when an electrical consumer is secured several times by block-by-side fuse switches, parts of the consumer can be energized over the parallel-located fuse switches provided with properly functioning fuse protection circuit, although there is obviously a fault in the consumer circuit.

Formålet med den foreliggende opfindelse er således at tilvejebringe en sikringsafbryder, som er således ud-35 formet, at aflåsningen af sikringsafbryderen er effektivt beskyttet mod ødelæggelse mod voldsom håndbetjening af afbrydervingen .The object of the present invention is thus to provide a circuit breaker which is designed so that the locking of the circuit breaker is effectively protected against destruction from excessive hand operation of the circuit breaker.

Det angivne formål opnås med en håndbetjent sikringsafbryder af den indledningsvis omhandlede art, som ifølge opfindelsen er ejendommelig ved den i krav l's kendetegnende del angivne udformning.The stated object is achieved with a hand operated circuit breaker of the kind initially provided, which according to the invention is peculiar to the design according to the characterizing part of claim 1.

5 Fordelagtige videreudviklinger og konstruktive karakte ristika ved opfindelsen er beskrevet i de yderligere krav.Advantageous further developments and constructive characteristics of the invention are described in the further claims.

Ved det ved opfindelsen tilvejebragte knæled i afbrydervingens aktiveringsarm opnås, at disse i sig selv ikke er stive. Ved udtaget sikringsindsats og dermed blokeret afbry-10 dervinge går knæleddet ved kraftig påvirkning af afbryderen ud af sin strakte stilling mod fjederbelastningen over til sin bøjede stilling. Herved påvirkes stoppet ikke med den fulde betjeningskraft, som ved kendte sikringsafbrydere flerdobles gennem vægtstangsvirkningen, men kun med en af fjederbelastnin-15 gen afhængig brøkdel heraf.By the knee joint provided by the invention in the actuating arm of the switching wing it is obtained that these are not in themselves rigid. Upon removal of the locking insert and thus blocked switching lever, the knee joint, when strongly exerted by the switch, goes out of its stretched position against the spring load to its bent position. In this way, the stop is not affected by the full operating force which, in the case of known circuit breakers, is multiplied by the lever action, but only by a fraction dependent on the spring load.

I de kendetegnende dele af krav 1-3 er beskrevet en konstruktionsteknisk særlig egnet løsning af den stillede opgave. Knæleddet påvirkes af en med dets omdrejningsakse koak-sialt tilvejebragt drejefjeder i udstrækningsretningen. Denne 20 drejefjeder kan næsten være integreret i leddet, hvorved der er frembragt en særlig kompakt og pladsbesparende opbygning.In the characterizing parts of claims 1-3, a construction technically particularly suitable solution of the stated task is described. The knee joint is affected by a pivot spring coaxially provided with its axis of rotation in the extension direction. This 20 swivel spring can almost be integrated into the joint, creating a particularly compact and space-saving structure.

Ved den særlige udpegning af fjederkonstanten sikres en problemløs virkning af den ved opfindelsen tilvejebragte sikringsafbryder. Da de kræfter, som kan overføres, er større end de 25 indkoblingskræfter, som skal overvindes, kan afbryderen sluttes til enhver tid, når smeltesikringsindsatsen er isat korrekt.By the special designation of the spring constant, a problem-free effect of the circuit breaker provided by the invention is ensured. Since the transferable forces are greater than the 25 switching forces to be overcome, the circuit breaker can be closed at any time when the melt protection insert is properly inserted.

Er afbrydervingen blokeret, overføres kun en brøkdel af påvirkningskraften gennem fjederen til den låsende del. Ved fjederens konstruktion er denne kraft så ringe, at der ikke 30 er nogen risiko for ødelæggelse af de aflåsende komponenter l i afbryderen. Derudover virker afbrydervingen ved korrekt isat sikringsindsats som kendte sikringsafbrydere. For ikke trænet personale er der således ingen ændring af betjeningen. Det særlige, sikkerhedsteknisk fordelagtige forhold ved den 35 ved opfindelsen tilvejebragte sikkerhedsafbryder fremtræder først ved fejlagtig betjening.If the switch wing is blocked, only a fraction of the force of force is transmitted through the spring to the locking part. In the spring construction, this force is so low that there is no risk of damaging the locking components 1 in the switch. In addition, the circuit breaker acts as well-known circuit breakers when properly installed fuses. Thus, for unskilled personnel, there is no change in the operation. The particular safety-advantageous relationship of the safety switch provided by the invention first appears through improper operation.

Eftersom det ifølge den kendetegnende del af krav 4 tilvejebragte knæled er placeret i området inden for aktiverings armen i nærheden af afbrydervingens omdrejningspunkt, kan der kun tilvejebringes en aktivering af afbryderen over 5 det knæksikrede ydre ben på akt i verings armen. Eftersom det indvendige ben er meget kort, har dette nemlig ikke nogen angrebsflade for aktivering af afbryderen. Herudover foreligger, som følge af knæledsplacering i nærheden af omdrejningspunktet i forhold til aflåsningspunktet, et omtrentligt lige-10 armet forhold. Herved lettes udpegningen af drejefjederen, eftersom dens fjederkonstant udelukkende skal være således tilvejebragt, at den maksimale kraft, som kan overføres, er mindre end brudkraften for låsningsstedet. Komplicerede beregninger for dette på grund af forskellige vægtstangsforhold kan bort-15 falde.Since, according to the characterizing part of claim 4, the knee joint provided is located in the area within the actuating arm near the pivot point of the switch wing, only actuating the switch above the knee-protected outer leg of the actuating arm can be provided. Because the inner leg is very short, this does not have an attack surface for activating the switch. In addition, due to knee joint placement near the pivot relative to the locking point, there is an approximately straight arm ratio. This facilitates the designation of the pivot spring, since its spring constant must be provided solely so that the maximum force that can be transmitted is less than the breaking force of the locking point. Complicated calculations for this due to different lever ratios may be omitted.

Ifølge det i den kendetegnende del af krav 5 anførte er knæleddet særlig godt beskyttet mod indgreb udefra og ukorrekt behandling. Eftersom drejefjederen ikke ligger ud over afbrydervingens konturflade, kan drejefjederens spidse ende 20 ikke forårsage beskadigelse af betjeningspersonalet.According to the characterizing part of claim 5, the knee joint is particularly well protected against external intervention and improper treatment. Since the pivot spring does not extend beyond the contour surface of the switch wing, the pivot end 20 of the pivot spring cannot cause damage to the operator.

Ved de ifølge den kendetegnende del af krav 6 på bøjningsretningssiden bag knæleddets tilvejebragte anlægsflader til fælles anlæg af det indre og det ydre ben mod hverandre undgås effektivt en overstrækning af knæleddet gennem på-25 virkning af afbrydervingen i åbningsretningen. Frem for alt tilvejebringes ved den vinklede udformning af anlægsfladerne ifølge krav 7 en stabil opbygning af knæleddet. Eftersom anlægsfladerne hovedsageligt ligger tæt op mod hinanden, fordeles de på anlægsfladerne virkende fladetryk regelmæssigt.In accordance with the characterizing part of claim 6 on the bending direction side behind the abutment surfaces provided for joint abutment of the inner and outer legs against each other, an overstretching of the knee joint is effectively avoided by the action of the switching ring in the opening direction. Above all, in the angular configuration of the abutment surfaces of claim 7, a stable structure of the knee joint is provided. Since the contact surfaces are mainly close to one another, the surface pressures acting on the contact surfaces are distributed regularly.

30 Disse egenskaber understøttes yderligere ved den kendeteg- nende del af krav 8, idet der er tilvejebragt særlig meget materiale til anlæg for knæleddet og de to anlægsflader. Den ved opfindelsen tilvejebragte sikringsafbryder virker kort fortalt med stor sikkerhed og er i vidt omfang beskyttet mod 35 beskadigelse.These properties are further supported by the characterizing part of claim 8, in that special material is provided for abutment of the knee joint and the two abutment surfaces. In short, the circuit breaker provided by the invention works with great security and is largely protected against damage.

Der er særlige fordele ved den ved opfindelsen tilvejebragte sikringsafbryder, når flere sikringsafbrydere, som beskrevet i krav 9-10, sættes sammen til en afbryderblok. Hvis nemlig kun en smeltesikringsindsats ikke er isat eller ikke 5 er isat korrekt, blokeres den i den pågældende sikringsafbryder placerede låsemekanisme, og gennem den stive forbindelse af drivarmene blokeres samtlige sikringsafbrydere. Da alle aktiveringsarmene på afbrydervingerne er sikret ved et knæled, er det ikke muligt at ødelægge aflåsningsmekanismen, og den 10 efter sikringsblokken tilsluttede forbruger kan hverken helt eller delvist sættes under spænding. Der er herved tilvejebragt en væsentlig sikkerhedsfordel i forhold til kendte afbryderblokke. En særlig fordelagtig simpel opbygning af afbrydervingen er beskrevet i krav 10. Hele blokken aktiveres 15 næsten af en eneste afbrydervinge, som er sikret ved et knæled.There are particular advantages to the circuit breaker provided by the invention when multiple circuit breakers, as described in claims 9-10, are assembled into a circuit breaker. If only one fuse insert is not inserted or not 5 is inserted correctly, the locking mechanism located in the respective circuit breaker is blocked and all the circuit breakers are blocked through the rigid connection of the drive arms. Since all the actuating arms of the switch wings are secured by a knee joint, it is not possible to destroy the locking mechanism, and the consumer connected to the locking block cannot be fully or partially energized. Thereby, there is provided a significant safety advantage over known switch blocks. A particularly advantageous simple structure of the switch wing is described in claim 10. The entire block is actuated almost by a single switch wing secured by a knee joint.

Opfindelsen forklares i det følgende nærmere under henvisning til tegningen, på hvilken: fig. 1 er en plan afbildning af en åbnet halvdel af sikringsafbryderhuset med korrekt isat sikringsindsats og med 20 belastningsafbryderen i indkoblingsstilling, fig. 2 er en plan afbildning modsvarende fig. 1 med fjernet smeltesikringsindsats og med afbrydervippen og belastningsafbryderen i udkoblingsstilling, fig. 3 er en plan afbildning modsvarende fig. 1 og 2 25 med udtaget smeltesikringsindsats og med en angivet aktivering af afbrydervippen trods blokering.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of an opened half of the circuit breaker housing with a properly inserted fuse insert and with the load circuit breaker in the switch-on position; FIG. 2 is a plan view similar to FIG. 1 with removed fuse insert and with the switch rocker and the load switch in the switch-off position, fig. 3 is a plan view corresponding to FIG. 1 and 2 25 with the removed melt-protection insert and with a specified activation of the switch rocker despite blocking.

Den i alle tre figurer med 1 angivne sikringsafbryder indbefatter to af isoleringsmateriale tilvejebragte hushalvdele 2, af hvilke kun en er anskueliggjort i figurerne. Opde-30 lingsfugen mellem hushalvdelene 2 forløber i figurernes teg- t ningsplan. De to hushalvdele 2 er i samlet tilstand nittet sam+1 men. Nitterne er ført igennem de gennemgående boringer 3. Sikringsafbryderen 1 indbefatter et sikringsrum 4 til optagelse af smeltesikringsindsatsen 5. Smeltesikringsindsatsen 5's 35 strømforsyningsforbindelse tilvejebringes af forbindelsesklemmerne 6, 7. Forbindelsesklemmen 7 er over tilledningen 10 forbundet elektrisk ledende med gevindstykket 8, i hvilket bThe fuse switch indicated in all three figures with 1 includes two housing halves 2 provided by insulating material, only one of which is illustrated in the figures. The splitting joint between the housing halves 2 proceeds in the drawing plan of the figures. The two house halves 2 are riveted together + 1 but together. The rivets are passed through the through bores 3. The fuse switch 1 includes a fuse compartment 4 for receiving the melt fuse insert 5. The fuse connection 5 of the fuse insert 5 is provided by the connection terminals 6, 7. The connection terminal 7 is connected over the conduit 10 with the threaded piece 8,

Smeltesikringsindsatsen 5 er i sin øverste og nederste ende udformet med et endekontaktstykke, nemlig topkontaktkappen 5 12 og bundkontaktkappen 13. Ved korrekt iskruet skruekappe 11 er der tilvejebragt en ledende forbindelse mellem skruekappen 11 og topkontaktkappen 12 på smeltesikringsindsatsen 5. Bund-kontaktstykket 13 på smeltesikringsindsatsen 5 ligger an mod et i figurens plan bevægeligt inden for huset tilvejebragt 10 modkontaktstykke 14. Modkontaktstykket 14 er ført til siden ud af sikringsrummet 4's område til en kontaktbro 15 på en ved afbrydervingen 16 aktiverbar belastningsafbryder. Kontaktbroen 15 ligger ved indkoblet belastningsafbryder (fig. 1) med begge sine kontaktstykker 17, 18 an mod modkontaktstykkerne 15 19, 20 på smeltesikringsindsatsen 5's modkontaktstykke 14, henholdsvis en med forbindelsesklemmen 6 forbunden kontaktflig 21.The melt fuse insert 5 is formed at its top and bottom end with an end contact piece, namely the top contact cap 5 12 and the bottom contact cap 13. A properly screwed screw cap 11 provides a conductive connection between the screw cap 11 and the top contact cap 12 of the fuse insert 5 of the bottom contact piece 13. 10 is in contact with a counterclockwise member 14 provided within the plane of the figure. The counterclockwise member 14 is guided laterally out of the area of the fuse space 4 to a contact bridge 15 on a load switch actuable by the switching wing 16. The contact bridge 15 lies at the switched load switch (Fig. 1) with both of its contact pieces 17, 18 abutting against the contact contacts 15 19, 20 on the counter contact piece 14 of the fuse insert 5 and a contact tab 21 connected to the connection terminal 6 respectively.

Kontaktbroen 15 påvirkes ved trykket af lukkefjedrene 22, 23 i retningen mod modkontaktstykkerne 19, 20 i indkob-20 lingsstillingen. Lukkefjedrene 22, 23 støtter med de nedre endestykker på husvæggen 24.The contact bridge 15 is actuated by the pressure of the closing springs 22, 23 in the direction towards the counter contact pieces 19, 20 in the switch-on position. The closing springs 22, 23 support with the lower end pieces on the housing wall 24.

En i isolationsmaterialet tilvejebragt trykstødstang 25 er med sin ene ende i berøring med oversiden af kontaktbroen 15. Trykstødstangen 25 er lejret således inden i sikrings-25 afbryderen 1, at den i lukkefjedr’ene 22, 23's trykretning, henholdsvis vinkelret på kontaktbroens længderetning, kan forskydes i sin længderetning mellem husvæggene 27. Ved sin placering oven på kontaktbroen 15 ligger den i mellemrummet mellem de i sluttet stilling ved kontaktbroen 15 elektrisk 30 ledende indbyrdes forbundne modkontaktstykket 19, 20.A thrust bar 25 provided in the insulating material is in contact with one end of it with the upper side of the contact bridge 15. The thrust bar 25 is mounted so within the circuit breaker 1 that in the pressure direction of the closing springs 22, 23 and perpendicularly to the longitudinal direction of the contact bridge, is displaced in its longitudinal direction between the housing walls 27. At its location on top of the contact bridge 15, it lies in the gap between the electrically conductive interconnecting piece 19, 20 connected in contact with the contact bridge 15.

Afbrydervippen 16 er lejret drejeligt omkring den 1 lodret på tegningsplanet tilvejebragte drejeaksel 28 på sikkerhedsafbryderen 1. Den er på den mod trykstødstangen 25 vendende ende 29 udformet med en udskæring 30 til optagelse 35 af et mod siden af afbrydervippen tilvejebragt styreorgan, hvilket styreorgan, som herefter benævnes afbrydervingestyre-The switch rocker 16 is pivotally mounted about the rotary shaft 28 provided vertically on the drawing plane 1.

0 organet 31, sammen med et yderligere styreorgan 32 tilvejebringer en som 33 benævnt vægtstang med knæled. Den frie ende af afbrydervingestyreorganet 31 er lejret drejeligt om omdrejningsakselen 28 for afbrydervingen 16. Styreorganet 5 32 virker som trykoverføringselement og er med sin frie ende 34 i berøring med den bagside af trykstødstangen 25, som vender væk fra kontaktbroen 15. Den frie ende 34 af styreorganet 32 hviler således i en på bagsiden af trykstødstangen 25 tilvejebragt kærv 35 på en sådan måde, at den kan drejes en 10 hvis vinkel i kærven 35's kileformede udskæring i figurens plan. Ved påvirkning af kontaktbroen 15 og trykstødstangen 25 gennem lukkefjedrene 22, 23 har styreorganet 32 til stadighed sin frie ende 34 placeret i kærven 35.The member 31, together with a further control member 32, provides a lever with knee joints referred to as 33. The free end of the switch wing control member 31 is pivotally mounted about the shaft 28 of the switch wing 16. The control member 5 32 acts as a pressure transmitting element and is in contact with its free end 34 in contact with the back side of the thrust bar 25 which faces away from the contact bridge 15. The free end 34 of the control means 32 thus rests in a groove 35 provided at the rear of the thrust bar 25 in such a way that it can be rotated 10 at an angle in the wedge-shaped cut of the groove 35 in the plane of the figure. By actuating the contact bridge 15 and the thrust bar 25 through the closing springs 22, 23, the control means 32 constantly has its free end 34 located in the notch 35.

Ved overføring af afbrydervingen 16 fra indkoblings-15 stillingen (fig. 1) til udkoblingsstillingen (fig. 2) bliver den med knæled udformede vægtstang gennem anlæg på den nedre ende af udskæringen 30 i afbrydervingen 16 trykket igennem sin strakte stilling (ikke anskueliggjort). Herved bevæger knæledsaksen 36 på den ved knæled tilvejebragte vægtstang 33 20 sig nedad i retning af kontaktbroen 15. Gennem styreorganet 32 trykkes trykstødstangen 25 herved nedad (pileretning 26) og kontaktbroen 15 fjernes fra modkontaktstykkerne 19, 20 (fig. 2).When transferring the switch wing 16 from the switch-on position (Fig. 1) to the switch-off position (Fig. 2), the lever-shaped bar through abutment on the lower end of the cut-out 30 in the switch-wing 16 is pushed through its stretched position (not shown). Hereby, the knee joint axis 36 of the lever 33 20 provided by the knee joint moves downwardly in the direction of the contact bridge 15. Through the control means 32, the pushing rod 25 is thereby pressed downwards (arrow direction 26) and the contact bridge 15 is removed from the counter contact pieces 19, 20 (Fig. 2).

Herefter beskrives kort opbygning og driftmåde af 25 den til afbrydervingen 16 knyttede aflåsningsindretning.Next, a brief structure and operation of the locking device associated with the switching wing 16 is described.

Den indbefatter i hovedsagen en i pilretningen 26 forløbende låsebøjle 37, som med'den mod kontaktstykkerne vendende ende 38 ved modkontaktstykket 14 er fastgjort ved siden af kontaktbroen i sikringsrummet 4's kantområde·. Den frie ende 39 30 af låsebøjlen 37 er placeret i området ved afbrydervingen 16's l endestykke 29. I afbrydervingen 16’s udkoblingsstilling ligger udskæringen 30 ud for låsebøjlens frie ende 39. Modkontaktstykket 14 på smeltesikringsindsatsen 5 påvirkes nedefra gennem en kontaktfjeder 40, som med sin nedre ende støtter 35 på væggen 24 på huset. I afbrydervingen 16's udkoblingsstilling (fig. 2) ligger udskæringen 30 ud for den frie ende 39 oIt generally includes a locking bracket 37 extending in the direction of arrow 26, which, with the end 38 facing the contact pieces, is secured to the counter contact piece 14 next to the contact bridge in the edge area of the fuse space 4. The free end 39 30 of the locking bracket 37 is located in the region of the end piece 29. of the switching blade 16 In the switching position 16 of the switching blade 16, the cut-out 30 lies outside the free end 39 of the locking bracket. The counter-contact piece 14 of the fuse insert 5 is actuated from below through a contact spring 40, which with its lower end supports 35 on the wall 24 of the housing. In the switch-off position of the switching wing 16 (Fig. 2), the cut-out 30 is opposite the free end 39 and

Ved påvirkningen af afbrydervingen 16 i indkob- 5 lingsretningen 41 kommer den frie ende 39 på låsebøjlen 37 til anlæg mod kanten 42 på udskæringen 30, hvorved afbrydervingen 16 blokeres. Denne situation er anskueliggjort i fig. 3.40, and the free end 39 of the locking bracket is displaced into the cutout 30. By actuating the switch wing 16 in the engagement direction 41, the free end 39 of the locking bracket 37 comes into contact with the edge 42 of the cutout 30, thereby blocking the switching wing 16. This situation is illustrated in FIG. Third

Afbrydervingen 16's opbygning og virkemåde forklares i det følgende under henvisning til denne figur: 10 Afbrydervingen 16 er udformet som en vægtstang og er lejret drejeligt om omdrejningsaksen 28 i sikringsafbryderen 1. Den er i hovedsagen L-formet, idet L-horisontalbenet 43 med sin frie ende går over i en omkring omdrejningsakselen 28 koncentrisk tilvejebragt cylinderformet valse 44. Den cylinder-15 formede valse 44 er i den del af dens omkredsområde, som vender mod kontaktstykkerne, udformet med udskæringen 30, i hvilken låsebøjlen 37 ved manglende eller ukorrekt isat smeltesikringsindsats 5 griber ind, og hvor ind i afbrydervinge-styreorganet 31 er placeret. Den del af den cylinderformede 20 valse 44, som vender mod kontaktstykkerne, virker således som drivarm 45 for den med knæled tilvejebragte vægtstang 33, hvorved den virker ved aktiveringen af kontaktbroen 15 over trykstødstangen 25. Den del af den cylinderformede valse 44, som vender bort fra kontaktstykkerne, benævnes sammen 25 med det L-f ormede stykke som aktiverings arm 46. Denne aktiveringsarm 46 er gennem det i overgangsområdet mellem den cylinderformede valse 44 og L-horisontalbenet 43 tilvejebragte knæled 49 opdelt i et indre ben 47 og et ydre ben 48. Knæleddet 49 påvirkes gennem en koncentrisk med sin ledakse 50 lej-30 ret drejefjeder 51 imod afbrydervingen 16's indkoblingsretning 41. Påvirkningskraften overføres gennem drejefjederen 51's frie ender 53, 54, idet disse støtter mod den i bøjningsretningen 55 vendende side af det indre ben 47 og det ydre ben 48.The structure and operation of the switching wing 16 are explained in the following with reference to this figure: 10 The switching wing 16 is designed as a lever and is rotatably rotated about the axis of rotation 28 of the circuit breaker 1. It is essentially L-shaped, the L horizontal leg 43 having its free The cylindrical roller 44 is formed in the portion of its circumferential region facing the contact pieces with the cut-off 30, in which the locking bracket 37, by missing or improperly inserted melt protection insert 5, is formed. engages and where the switching wing control means 31 is located. The portion of the cylindrical roller 44 facing the contact pieces thus acts as a driving arm 45 for the lever 33 provided by the knee joint, thereby acting upon the activation of the contact bridge 15 over the thrust bar 25. The portion of the cylindrical roller 44 facing away from the contacts, 25 together with the Lf-shaped piece are referred to as actuating arm 46. This actuating arm 46 is divided into an inner leg 47 and an outer leg 48 through the knee joint 49 provided in the transition region between the cylindrical roller 44 and the L horizontal leg 43. 49 is actuated by a concentric pivot spring 51 positioned by its articulated axis 50 against the switching direction 41 of the switching wing 16. The force of force is transmitted through the free ends 53, 54 of the pivot spring 51, which abut against the side of the inner leg 47 facing in the bending direction 55. ben 48.

Drejefjederen er tilvejebragt med en sådan fjederkonstant, 35 at de gennem denne overførte kræfter er større end de indkoblingskræfter, som skal overvindes, men mindre end den afspær- δ DK 165082 Β ο ringskraft, som tilvejebringes ved låsebøjlen 37's indgreb 56. Herved forbliver knæleddet 49 ved aktivering af den ikke--blokerede afbrydervinge 16 (fig. 1) ved fjederbelastningen hovedsagelig i sin strakte stilling. Ved blokeret afbrydervin-5 ge (fig. 3) overføres knæleddet 49 til sin bøjede stilling.The swivel spring is provided with such a spring constant that, through this transmitted force, it is greater than the coupling forces to be overcome but less than the locking force provided by the locking lever 37's engagement 56. This remains the knee joint 49 by activating the unblocked switch wing 16 (Fig. 1) at the spring load mainly in its stretched position. At blocked switch angle (Fig. 3), the knee joint 49 is transferred to its bent position.

I fig. 3 anskueliggøres en særlig fordelagtig udførelsesform af udformningen af afbrydervingen 16 med knæleddet 49. Knæleddet 49 ligger nemlig i den i overgangsområdet mellem den cylinderformede valse 44 og L-horisontalbenet 43. place-10 rede udskæring 57, uden at de frie ender 53, 54 af drejefjede-ren 51 stikker frem ud over afbrydervingen 16's kontur. Ud fra denne udskæring 57 strækker sig en delefuge 58 langs den cylinderformede valse 44’s periferi. Det indre ben 47 og det ydre ben 48 er udformet med mod hinanden vendende anlægsflader 15 59, 60, hvilke flader ligger mod hinanden, når knæleddet 49 (fig. 1, 2) er placeret i strækstillingen. Anlægsfladerne 59, 60*s vinkelform er således på denne måde fordelagtig, idet aktiveringskræfter i næsten hvilken som helst retning gennem vinkelfladernes tætte anlæg fordeles så godt som muligt. Den 20 særlige udformning af afbrydervingen 16 som et L-stykke og en cylinderformet valse 44 tilvejebringer herudover en forøgelse af størrelsen af de mod hinanden vendende anlægsflader 59, 60, hvorved de optrædende særlige fladetryk yderligere bliver reduceret.· 25 Gennem flere, ved siden af hinanden parallelplacerede sikringsafbrydere 1 ifølge fig. 1-3, kan der tilvejebringes en flerpolet afbryderblok. I tilslutning til sådanne afbryder-blokke er de enkelte afbrydervinger 16 lejret koaksialt på en omdrejningsaksel 28. I tilknytning hertil, vil det være 30 en fordel ved opfindelsen, om de som indre ben 47 på aktive- ringsarmene 46 henholdsvis som drivarme 45 tilvejebragte cylinderformede valser 44 er stift forbundet med hinanden, I praksis opnås dette ved, at der til de enkelte sikringsafbrydere 1 i sikringsblokken anvendes en i ét stykke udformet gennem-35 gående cylinderformet valse 44. Gennem denne stive forbindelse sikres det, at hele sikringsblokken ved fastlåsning af en afIn FIG. 3, a particularly advantageous embodiment of the design of the switching wing 16 is shown with the knee joint 49. The knee joint 49 is located in the cut-away position 57 in the transition area between the cylindrical roller 44 and the L-horizontal leg 43, without the free ends 53, 54 of pivot spring 51 protrudes beyond the contour of switch switch 16. From this cut 57, a dividing joint 58 extends along the periphery of the cylindrical roller 44. The inner leg 47 and the outer leg 48 are formed with facing abutment surfaces 15 59, 60 which face each other when the knee joint 49 (Figs. 1, 2) is placed in the stretching position. The angular shape of the contact surfaces 59, 60 * is thus advantageous in this way, since activation forces are distributed in almost any direction through the close abutment of the angular surfaces as best as possible. In addition, the special design of the switching wing 16 as an L-piece and a cylindrical roller 44 provides an increase in the size of the facing contact surfaces 59, 60, thereby further reducing the occurring special surface pressures. interlocking fuse switches 1 according to FIG. 1-3, a multi-pole switch block may be provided. In connection with such switch blocks, the individual switching wings 16 are coaxially mounted on a rotary shaft 28. In addition, it will be an advantage of the invention if the cylindrical rollers provided as inner legs 47 on the actuating arms 46 or as drive arms 45, respectively. 44 is rigidly connected to each other, in practice this is achieved by the use of a single-piece continuous cylindrical roller 44 for the individual circuit breakers 1 in the fuse block. Through this rigid connection, the entire fuse block is secured by locking a of

0 sikringsafbryderne 1 gennem den pågældende aflåsningsbøjle 37's indgreb i en udskæring 30 er låst. Eftersom det ydre ben 48 på afbrydervingen 16 samtidig kan knække i knæleddet 49, kan sikringsblokken ikke aktiveres, ligesom indgrebet 56 ved 5 en voldsom omlægning af afbrydervingen 16 til indkoblingsposition (fig. 1) ikke kan ødelægges. Ved den stive forbindelse af det ydre ben 48 på aktiveringsarmene 46 på de enkelte sikringsafbrydere 1 virker disse i en samlet enhed som en flerpodet sikringsblok, idet aflåsningsfunktionen ved manglen-10 de eller ikke korrekt isat smeltesikringsindsats 5 udgående fra en enkelt pol altid forhindre aktivering af den samlede blok. I dette tilfælde er tilvejebringelsen af en stiv forbindelse af de cylinderformede valser 44 til frembringelse af en sammenhængende komponent overflødig. Blokeres nemlig kun 15 en drivarm 45 ved indgreb, kan der, på grund af den stive forbindelse af de ydre ben 48 med hinanden, kun overføres et sammenbøjningsdrejningsmoment på samtlige knæled, mens der ikke kan overføres noget indkoblingsmoment mere på de ikke blokerede drivarme.0 the circuit breaker 1 through the engagement of the respective locking bracket 37 in a cutout 30 is locked. Since the outer leg 48 of the switch wing 16 can simultaneously break in the knee joint 49, the locking block cannot be actuated, just as the engagement 56 at 5 does not violently change the switch wing 16 to switch-on position (Fig. 1). In the rigid connection of the outer leg 48 of the actuating arms 46 of the individual fuse switches 1, these act in a single unit as a multipoint fuse block, the locking function of the missing or incorrectly inserted fuse insert 5 starting from a single pole always preventing activation of the the total block. In this case, the provision of a rigid connection of the cylindrical rollers 44 to produce a coherent component is superfluous. Because only a driving arm 45 is blocked by engagement, due to the rigid connection of the outer legs 48 with each other, only a bending torque can be transmitted on all knee joints, while no more torque can be applied to the non-blocked driving arms.
