Description
Det er vanlig å opprette forbindelsen mellom overdelen og underdelen av et hus for elektrisk installasjonsutstyr, som brytere, stikkontakter, lyssignaler m.v. ved hjelp av skruer og gjenge-hylser. Det samme er tilfelle, når husets underdel utgjores av en skjult anordnet stikkontakt og det som husets overdel benyttes et deksel som er utformet i overensstemmelse med den aktuel-le, monterte installasjon. It is common to establish the connection between the upper part and the lower part of a house for electrical installation equipment, such as switches, sockets, light signals etc. using screws and threaded sleeves. The same is the case when the lower part of the house is made up of a hidden socket and the upper part of the house uses a cover that is designed in accordance with the current installed installation.
I den senere tid er husene for vanntett apparatur forsynt med hurtigkoblinger i stedet for skrueforbindelse, hvilket skal for-enkle apparatets montering og redusere monteringstiden. In recent times, the housings for waterproof equipment have been fitted with quick connectors instead of screw connections, which should simplify the installation of the equipment and reduce the assembly time.
En kjent anordning består i at huset fremstilles av en termoplast, at husets underdel forsynes med inngrepsfordypninger i overkanten, mens husets overdel forsynes med knaster som går i inngrep med fordypningene og sammen med disse danner en inngreps-Io A known arrangement consists in the housing being manufactured from a thermoplastic, the lower part of the housing being provided with engagement recesses in the upper edge, while the upper part of the housing is provided with lugs which engage with the recesses and together with these form an engagement Io
as. as.
Ved en annen utforelse for forbindelse av husets over- og underdel benyttes en dreiedel av metall, som overst er forsynt med et sylindrisk skruehode og har en omtrent rettvinklet boyd hake ved fotenden. Husets over- og underdel har uttagninger tilpasset dreiedelen med hake og underdelen er ved uttagningens bunn forsynt med.et skråplan,, bak hvilket metalldreiedelens hake kan gripe inn. Gjensidig tiltrekking av de to husdeler skjer ved en dreiebevegelse av dreiedelen og ved at haken glir på skråplanet. In another embodiment for connecting the upper and lower parts of the housing, a metal turning part is used, which is provided with a cylindrical screw head at the top and has an approximately right-angled boyd hook at the foot end. The upper and lower parts of the housing have recesses adapted to the turning part with a hook and the lower part is provided at the bottom of the recess with an inclined plane, behind which the metal turning part's hook can engage. Mutual attraction of the two housing parts occurs by a turning movement of the turning part and by the hook sliding on the inclined plane.
Ved en annen utforelse fremstilles de to husdelene fortrinnsvis av duroplast.. Husets underdel får to hylser av termoplast og mellom husets overdel og hver hylses hode dannes en inngreps- sperring av inngrepsknaster eller inngrepsspor og -knaster. In another embodiment, the two housing parts are preferably made of duroplast. The lower part of the housing gets two sleeves made of thermoplastic and between the upper part of the housing and the head of each sleeve, an engagement barrier is formed by engagement lugs or engagement grooves and lugs.
Ved samtlige kjente hurtigkoblinger er monteringen forholdsvis enkel, men demontering er vanskelig, fordi den forutsetter et visst kjennskap til koblingssystemet. Dessuten er oppbudet for masseartikkelen "installasjonsutstyr" for hoyt, især med hen-blikk på verktoyomkostningene. With all known quick couplings, assembly is relatively simple, but disassembly is difficult, because it requires a certain knowledge of the coupling system. In addition, the bid for the mass article "installation equipment" is too high, especially in view of the tool costs.
Oppfinnelsen går ut på å tilveiebringe en hurtigkobling, som unngår store omkostninger og vanskeligheter ved demontering og som spesielt muliggjbr den velkjente påvirkning av hurtigkob-lingen med et skrujern både ved montering og demontering. The invention is to provide a quick coupling, which avoids large costs and difficulties during disassembly and which in particular enables the well-known influence of the quick coupling with a screwdriver both during assembly and disassembly.
Denne oppgave loses ifolge oppfinnelsen ved at koblingen består av en gjengehylse eller gjenge e.l. utformet hhv. innpresset i husets underdel og av en gjengeskrue e.l. med sterk stigning. According to the invention, this task is solved by the coupling consisting of a threaded sleeve or thread or the like. designed respectively pressed into the lower part of the housing and by a threaded screw etc. with a strong rise.
Ifolge en videreforing av oppfinnelsens ide foretrekkes en anordning med flere gjenger, idet sammenskruingstiden dermed blir kortere. According to a continuation of the idea of the invention, a device with several threads is preferred, as the screwing time is thus shorter.
Gjengene er videre med fordel anordnet i husunderdelens festedomer. Dermed plasseres befestigelsen i et volum som allerede er gått tapt som bryterrom. The gangs are also advantageously arranged in the lower part of the house's fixing doms. In this way, the attachment is placed in a volume that has already been lost as a switch room.
Ifolge oppfinnelsen kan det benyttes en metallskrue som ligner en plateskrue og en flensbøssing eller en på- According to the invention, a metal screw that resembles a plate screw and a flange bushing or an on-
formet eller innpresset gjenge, hvor gjengene har meget sterk stigning. Ved denne utformning av koblingen tar sammenskruingen vesentlig kortere tid. shaped or pressed-in thread, where the threads have a very strong pitch. With this design of the coupling, screwing together takes significantly less time.
Koblingselernentet kan videre bestå av en skrue og en gjengebossing med flere gjenger. Det kan f.eks. fremstilles eller benyttes en skrue og en gjengebossing med en gjengestigning på 0,5 mm og tre parallelt forlopende gjenger, slik at tre gjenger blir virksomme som hold ved en omdreining - den vanlige, lang-somme skruprosess reduseres med 2/3 av tiden. Anordninger av nevnte type er i og for seg kjent og benyttes f.eks. ved fylle-pennholdere og spesielt.ved beholdere for kosmetiske artikler. Det må dog konstateres, at ingen hittil er kommet på oppfinnel sens ide, men at man har sokt og funnet langt mer kompliserte losninger. The coupling element can also consist of a screw and a threaded boss with several threads. It can e.g. a screw and a threaded boss with a thread pitch of 0.5 mm and three parallel running threads are produced or used, so that three threads become effective as a hold during one turn - the usual, slow screwing process is reduced by 2/3 of the time. Devices of the aforementioned type are known in and of themselves and are used e.g. by fountain pen holders and especially by containers for cosmetic articles. It must be noted, however, that no one has so far come up with an inventive idea, but that far more complicated solutions have been sought and found.
Ved anordning av gjengene i domene må skruen ha storre.diameter. Det er derfor hensiktsmessig å benytte skruedeler hhv. skiver som er festet, til en kjerne. When arranging the threads in domain, the screw must have a larger diameter. It is therefore appropriate to use screw parts or discs that are attached to a core.
Tegningens figurer skal illustrere oppfinnelsen. Som utforelses-eksempel på et elektrisk installasjonsutstyr er det valgt en bryter. Fig. 1 viser et snitt gjennom et vanntett hus med innebygget bryter, fig. 2 et oppriss av husets nedre del med bryteren. Fig. 3 viser en metallskrue som forbindelseselement, hvilken ligner; en plateskrue og fig. 4 viser en skrue med flere gjenger som forbindelseselement, mens fig. 5 viser avviklingen av gjengene for skruen ifolge fig. 4. I fig. 6 er det vist et snitt etter linjen A-A i fig. 7, gjennom en annen utforelsesform av et vanntett hus, mens fig.. 7 viser et oppriss av husets nedre del med innebygget bryter og fig. 8 viser en skrue med stor gj engedi ameter. The drawing's figures shall illustrate the invention. A switch has been chosen as an embodiment of an electrical installation device. Fig. 1 shows a section through a waterproof housing with a built-in switch, fig. 2 an elevation of the lower part of the housing with the switch. Fig. 3 shows a metal screw as a connecting element, which resembles; a plate screw and fig. 4 shows a screw with several threads as a connecting element, while fig. 5 shows the unwinding of the threads for the screw according to fig. 4. In fig. 6 shows a section along the line A-A in fig. 7, through another embodiment of a waterproof house, while fig. 7 shows an elevation of the lower part of the house with a built-in switch and fig. 8 shows a high speed screw.
I fig. 1 og 2 er husunderdelen betegnet med 1, overdelen med 2 og den innebygde bryter med 3. Vanntetning oppnås på kjent må-te med tetningen 4. Til sammenkobling av husunderdelen 1 med husoverdelen 2 benyttes gjengebbssingene 5 og skruene 6 med flere gjenger, som er vist separat i fig. 4 og 5. Av avviklingen ifolge fig. 5 fremgår at skruen og bossingen f.eks. har tredobbelt gjenging. Ifolge fig.. 1 og 2 er skrueforbindélsene 5 og 6 anordnet i en ribbe i husdelen 1. I stedet for skruefor-bindelsen ifolge fig. 4 og 5 kan man også benytte metallskruen ifolge fig. 3 med tilsvarende motgjenging. In fig. 1 and 2, the lower part of the housing is denoted by 1, the upper part by 2 and the built-in switch by 3. Waterproofing is achieved in a known way with the seal 4. To connect the lower part of the housing 1 with the upper part of the housing 2, the threaded fasteners 5 and the screws 6 with several threads are used, which are shown separately in fig. 4 and 5. Of the liquidation according to fig. 5 it appears that the screw and bossing, e.g. has triple threading. According to fig. 1 and 2, the screw connections 5 and 6 are arranged in a rib in the housing part 1. Instead of the screw connection according to fig. 4 and 5, you can also use the metal screw according to fig. 3 with corresponding countermeasures.
Ved utforelseseksemplet ifolge fig. 6-8, hvor husoverdelen er betegnet med 8, underdelen med 9, tetningen med' 10 og den innebygde bryter med 11, er koblingsorganene anordnet i husunderdelens 9 festedomer 12. Bryterrommet innsnevres dermed ikke ved innebygde ribber. Da festedomen 12 har stor diameter, benyttes ifolge fig. 8 en skrue bestående av en kjerne 13 og et påsatt gjengestykke 14, som f.eks. griper inn i gjenger 15 som er pres-set inn i husunderdelens 9 materiale. In the embodiment example according to fig. 6-8, where the upper part of the housing is denoted by 8, the lower part by 9, the seal by 10 and the built-in switch by 11, the coupling means are arranged in the fastening domes 12 of the lower part of the housing 9. The switch space is thus not narrowed by built-in ribs. As the attachment dome 12 has a large diameter, according to fig. 8 a screw consisting of a core 13 and an attached threaded piece 14, which e.g. engages in threads 15 which are pressed into the material of the lower housing part 9.
