Description
Oppfinnelsen angår en sikringssokkel med en i et hus innebygd bryter for en smeltesikring med endekontaktkappe, der smelteinnsatsen er fastholdt i en holder som er innskrudd i.en gjengeinnsats som står i forbindelse med strømutgangen, hvilken innsats står i forbindelse med en fotkontakt over smelteinnsatsen, og der fotkontakten tjener som strømtil-førsel, idet strømtilførselen over fotkontakten kan brytes ved hjelp av bryteren. The invention relates to a fuse base with a switch built into a housing for a fusible link with an end contact cap, where the fusible insert is held in a holder which is screwed into a threaded insert which is connected to the current output, which insert is connected to a foot contact above the fusible insert, and where the foot contact serves as a power supply, as the power supply via the foot contact can be interrupted with the help of the switch.
Ved slike sikringssokler blir bryteren betjent før utskiftingen av en defekt smeltesikring for å sikre at det ikke står farlige spenninger på kontaktene ved utskiftingen. Utkoplingen skjer også når det skal foretas mindre repara-sjoner i den elektriske installasjonen, da den intakte smeltesikringen.skrus noe ut av holderen eller tas ut for å øke sikkerheten. In the case of such fuse bases, the switch is operated before the replacement of a defective fuse to ensure that there are no dangerous voltages on the contacts during the replacement. The disconnection also occurs when minor repairs are to be carried out in the electrical installation, as the intact fuse is unscrewed somewhat from the holder or removed to increase safety.
Det er kjent ved slike sikringssokler å forsyne bryteren med et betjeningshåndtak som har en ansats som i innkoplingsstilling dekker over smeltesikringens holder. It is known for such fuse sockets to provide the switch with an operating handle which has a shoulder which, in the switched-on position, covers the fuse holder.
For uttagelse av smeltesikringen må bryteren bringes i sin utkoplingsstilling. Det er således en tvangsmessighet til-stede, nemlig først utkopling deretter utskifting. Ved inn-setting av smeltesikringen igjen er dette ikke tilfelle. To remove the fuse, the switch must be brought to its disconnection position. There is thus a compulsion present, namely first disconnection then replacement. When inserting the fuse again, this is not the case.
Da smeltesikringen også skiftes av ikke-faglærte er det fare for at smeltesikringen bare settes inn så langt at det akkurat fås kontakt med fotkontakten. Etter innkopling kan det da på grunn av dårlig kontakt mellom smeltesikring og fotkontakt respektive gjengeinnsatsen i holderen oppstå smeltesteder, gnistdannelser, forhøyelse av overgangsmot-standen o. 1. som påvirker funksjonen av sikringssokkelen og i ekstreme tilfeller til ødeleggelser av innretningen. Ved ikke helt fjernet smelteinnsats kan en tredjemann komme til og kople inn bryteren igjen, slik at det elektriske anlegg som opprinnelig f.eks. var koplet ut for reparasjon igjen settes under spenning. As the fuse is also replaced by non-specialists, there is a risk that the fuse is only inserted so far that contact is made with the foot switch. After switching on, due to poor contact between the fuse and the foot contact or the threaded insert in the holder, melting points, sparks, an increase in the transition resistance, etc. 1. can occur, which affect the function of the fuse base and in extreme cases lead to destruction of the device. If the fuse insert is not completely removed, a third party can come and switch the switch back on, so that the electrical system that was originally e.g. was disconnected for repair again put under voltage.
Fra U.S.-patent nr. 3.009.036 er det kjent en sikringssokkel for en smeltesikring, der innretningen er forsynt med en bryter. Bryteren blir sperret mot innkopling mens smeltesikring skiftes, dvs. at bryteren ikke vil kunne koples inn ved uttatt smeltesikring eller ved utilstrekkelig inntatt sikring. Innretningen ifølge det amerikanske patentet er tilpasset smeltesikring med kniv-kontakter og hele innretningen er komplisert og kostbar. From U.S. patent no. 3,009,036, a fuse base for a fuse is known, where the device is provided with a switch. The switch is blocked from being switched on while the fuse is being replaced, i.e. the switch will not be able to be switched on if the fuse is removed or if the fuse is insufficiently inserted. The device according to the American patent is adapted to fuse protection with knife contacts and the whole device is complicated and expensive.
Hensikten med foreliggende oppfinnelse er å for-bedre og forenkle slike innretninger, slik at de blir tilpasset en sikringssokkel for smeltesikring med endekontaktkappe der smeltesikringen er fastholdt i en holder som er innskrudd i en gjengeinnsats som står i forbindelse med strømutgangen. The purpose of the present invention is to improve and simplify such devices, so that they are adapted to a fuse socket for a fuse with an end contact cap where the fuse is held in a holder which is screwed into a threaded insert which is in connection with the current output.
Dette oppnås ifølge oppfinnelsen ved en anordning ved en sikringssokkel med eri i et hus innbygd bryter for en smeltesikring med endekontaktkappe, der smeltesikringen er fastholdt i en holder som er innskrudd i en gjengeinnsats som star i forbindelse med strømutgangen, hvilken innsats står i forbindelse med en fotkontakt over smeltesikringen, og hvilken fotkontakt tjener som strømtilførsel, idet strømtilførselen over fotkontakten kan brytes ved hjelp av bryteren, og at bryteren i sin stilling med fjernet eller ikke tilstrekkelig innskrudd sikring er blokkert ved hjelp av en sperreinnretning, og det karakteristiske består i at sperreinnretningen består av en bøyle hvis svingebevegelse bevirkes av den under f jær-spenning stående fotkontakten, og at den frie enden av bøylen griper under en sperrenese på koplingsarmen. According to the invention, this is achieved by a device in a fuse base with a switch built into a housing for a fusible link with an end contact cap, where the fusible link is held in a holder that is screwed into a threaded insert that is in connection with the current output, which insert is in connection with a foot contact above the fuse, and which foot contact serves as a power supply, since the power supply via the foot contact can be interrupted using the switch, and that the switch in its position with the fuse removed or not sufficiently screwed in is blocked by means of a blocking device, and the characteristic is that the blocking device consists of a hoop whose swing movement is caused by the foot contact standing under spring tension, and that the free end of the hoop grips under a locking nose on the coupling arm.
Konstruksjonen ifølge oppfinnelsen blir meget enkel, driftssikker og billig i fremstilling. De fordeler som oppnås ved oppfinnelsen består særlig i at bryteren, som på forhånd er slått av, ved fjernet smeltesikring resp. ikke tilstrekkelig innskrudd sikring, hverken bevisst eller utilsiktet kan koples inn igjen. Først etter en full-stendig innskruing av sikringen og oppnåelse av tilstrekkelig kontakttrykk mellom sikringen og motkontakten, blir virkningen av sperreinnretningen opphevet. The construction according to the invention is very simple, reliable and cheap to manufacture. The advantages achieved by the invention consist in particular in that the switch, which has been switched off in advance, when the fuse is removed resp. the fuse is not screwed in sufficiently, neither deliberately nor unintentionally can it be switched back on. Only after the fuse has been completely screwed in and sufficient contact pressure has been achieved between the fuse and the counter contact, is the effect of the blocking device cancelled.
En fordelaktig utførelsesform ved oppfinnelsen er karakterisert ved at bøylen samvirker med en membran som gir et akustisk signal som gir en indikasjon på at sperreinnretningen er i virksomhet. An advantageous embodiment of the invention is characterized in that the hoop cooperates with a membrane which gives an acoustic signal which gives an indication that the locking device is in operation.
Oppfinnelsen skal i det følgende forklares nærmere under henvsining til tegningen, som viser et utførelses-eksempel for oppfinnelsen. Fig. 1 viser et snitt gjennom en med bryter forsynt sikringssokkel med innsatt smeltesikring. Fig. 2 viser et snitt gjennom en med bryter forsynt sikringssokkel ifølge fig. 1, uten smeltesikring og sikring-ens holder i utkoplet tilstand. Sikringssokkelen består av to identiske hushalvdeler 1, idet den fremre hushalvdel ikke er tegnet. Hushalvdelene er forbundet med hverandre ved hjelp av nagler 2. For til-kopling av ledninger tjener klemmer 3,3' ved fotkontakten 4 resp. ved den gjengede innsats 5. Strømtilførselen over fotkontakten 4 kan brytes ved hjelp av en bryter 6, f.eks. for utskifting av en defekt smeltesikring. Ved utskruing av holderen 7 for smeltesikringen 8 beveger fotkontakten 4 seg oppover ved hjelp av en trykkfjær 9 inntil anslagsflaten 10. Derved blir en på fotkontakten 4 lagret bøyle 11 svingt så langt utover at den for sperring av utkoplingsarmen 12 tjenende ende 13 kommer til å ligge innen svingeområdet for en sperrenese 14 på utkoplingsarmen 12. Bryteren 6 kan derved ikke koples inn. Først ved innskruing av holdeinn-retningen 7 med smeltesikringen 8, hvor smeltesikringen holdes i holderen 7 ved hjelp av en holdefjær 18, trykkes fotkontakten nedover ved hjelp av den nedre kontaktkappen 15 på smeltesikringen 8, slik at bøylen 11 beveger seg innover og enden 13 svinges igjen utenfor svingeområdet for sperre-nesen 14 på koplingsarmen 12. Bryteren 6 kan da koples inn. For oppnåelse av forskriftsmessig drift av sikringssokkelen er kontakttrykket mellom endekontaktkappen 15,16 og dens kontaktmotlager av største viktighet. For at man skal kunne oppfatte at denne driftstilstand er oppnådd, frembringes det et aktustisk signal ved hjelp av et membran 17 som påvirkes av bøyleenden 13. Dette signal er hørbart både ved utskruing og ved innskruing av smeltesikringen 8 og tjener til å indikere at bryteren kan betjenes. In the following, the invention will be explained in more detail with reference to the drawing, which shows an embodiment of the invention. Fig. 1 shows a section through a switch-equipped fuse base with an inserted fuse. Fig. 2 shows a section through a safety socket provided with a switch according to fig. 1, without fuse and the fuse holder in the disconnected state. The fuse base consists of two identical housing halves 1, the front housing half not being drawn. The housing halves are connected to each other by means of rivets 2. For connecting cables, clamps 3,3' at the foot contact 4 or by the threaded insert 5. The power supply via the foot contact 4 can be broken using a switch 6, e.g. for the replacement of a defective fuse. When the holder 7 for the fuse 8 is unscrewed, the foot contact 4 moves upwards with the help of a pressure spring 9 until the stop surface 10. Thereby a hoop 11 stored on the foot contact 4 is swung so far outwards that the end 13 serving to block the disconnection arm 12 comes to rest within the swing area of a locking nose 14 on the disconnection arm 12. The switch 6 cannot thereby be engaged. First when screwing in the holding device 7 with the fuse 8, where the fuse is held in the holder 7 by means of a holding spring 18, the foot contact is pressed downwards by means of the lower contact cap 15 on the fuse 8, so that the hoop 11 moves inwards and the end 13 is swung again outside the swing area for the locking nose 14 on the coupling arm 12. The switch 6 can then be switched on. In order to achieve proper operation of the fuse base, the contact pressure between the end contact cap 15,16 and its contact counter bearing is of utmost importance. In order to be able to perceive that this operating condition has been achieved, an acoustic signal is produced by means of a membrane 17 which is affected by the hoop end 13. This signal is audible both when unscrewing and when screwing in the fusible link 8 and serves to indicate that the switch can operated.
