Description

Starterholder for lysstoffrørlamper. Starter holder for fluorescent lamps.

Starterholdere for lysstoffrørlamper er alminnelig kjent. Man skiller mellom dem hvis klemskruer er tilgjengelig fra forsiden og dem hvis klemskruer er tilgj engelige fra baksiden ved forbindelse av tilførsels-ledninger. Alt etter behov er det da nød-vendig med to forskjellige utførelser, slik at man for hver utførelse trenger et annet verktøy. Dette fører imidlertid til økte fremstillingsomkostninger ved en så liten gjenstand. Hensikten med oppfinnelsen er derfor å tilveiebringe en starterholder som ved hjelp av bare et enkelt verktøy kan dekke begge utførelsesformer. Starter holders for fluorescent lamps are generally known. A distinction is made between those whose clamping screws are accessible from the front and those whose clamping screws are accessible from the back when connecting supply lines. Depending on the need, it is then necessary to have two different versions, so that you need a different tool for each version. However, this leads to increased manufacturing costs for such a small object. The purpose of the invention is therefore to provide a starter holder which, with the help of just a single tool, can cover both embodiments.

Ifølge oppfinnelsen har holderhuset ialt fire innleggsfordypninger for kontakt-enes to tilslutningsklemmer, hvorav to kommer til anvendelse samtidig. I en starterholder befinner det seg vanligvis to kontakter som er bestemt for de to kon-taktstifter som gir kontakt til lysstoffrøret. Hver kontakt er forsynt med en tilslut-ningsklemme for ledningen. Av de fire innleggsfordypninger i den nye innretningen hører alltid to diagonalt overfor hverandre liggende, til en holderenhet og er forsynt med tilslutningsklemmer. According to the invention, the holder housing has a total of four insert depressions for the contacts' two connection terminals, two of which are used at the same time. In a starter holder, there are usually two contacts that are intended for the two contact pins that make contact with the fluorescent tube. Each contact is provided with a connection clamp for the cable. Of the four insert recesses in the new device, two diagonally opposite each other always belong to a holder unit and are provided with connection clamps.

Videre består oppfinnelsen i at to sam-menhørende innleggsfordypninger for de utenfra betjenbare klemskruer er anordnet i husunderdelen, og at de to andre innleggsfordypninger er anordnet i husdekslet. Hvis man altså trenger klemme-anordninger hvor klemskruene skal betjenes fra dekselsiden, benyttes de innleggsfordypninger for klemmene som er anordnet i husoverdelen. Trenges derimot betjening fra baksiden, anordnes tilslut-21 f-84<02> — 120554 — 1 blad tegninger. Furthermore, the invention consists in that two matching insert recesses for the externally operable clamping screws are arranged in the lower part of the housing, and that the other two insert recesses are arranged in the housing cover. If you therefore need clamping devices where the clamping screws are to be operated from the cover side, the insert depressions for the clamps which are arranged in the upper part of the housing are used. If, on the other hand, operation from the rear is required, the end-21 f-84<02> — 120554 — 1 sheet of drawings is provided.

ningsklemmene i de to andre innleggsfordypninger da adkomsten til klemskruene her befinner seg i husunderdelen. ning clamps in the other two insert recesses, as access to the clamping screws here is located in the lower part of the housing.

Kontaktene er fortrinnsvis fremstillet av ett stykke og for de forskjellige formål en gang anordnet ved klemskruens fot og en annen gang ved klemskruens hode. Hvis de er anordnet ved klemskruens fot, tilsvarer de betjening av klemskruen fra forsiden, og er de anordnet ved skruens hode, er den beregnet på betjening fra baksiden. The contacts are preferably made of one piece and for the different purposes once arranged at the base of the clamping screw and another time at the head of the clamping screw. If they are arranged at the base of the clamping screw, they correspond to operation of the clamping screw from the front, and if they are arranged at the head of the screw, it is intended for operation from the rear.

Husdelen er således utformet at begge kontaktinnretningene oppnår samme gode stilling. Innleggsfordypningene for kontaktstiftene befinner seg på kjent måte i husets deksel. Husoverdelen og husunderdelen har dessuten mellom de to innsats-steder for tilslutningsklemmene, hull for organer som holder de to husdeler sammen. Videre er sideveggene og innleggsfordypningene for tilslutningsklemmene gjen-nombrutt på siden for å kunne føre tilslut-ningstrådene inn i klemmene. I denne hen-sikt befinner betjeningsåpningene til tilslutningsklemmene seg ved den klemanord-ning som betjenes fra baksiden i husoverdelen, og for betjening fra forsiden i husunderdelen. The housing part is designed in such a way that both contact devices achieve the same good position. The insert depressions for the contact pins are located in a known manner in the housing cover. The upper part of the housing and the lower part of the housing also have, between the two insertion points for the connection clamps, holes for organs that hold the two parts of the housing together. Furthermore, the side walls and insert recesses for the connection clamps are broken through on the side to be able to lead the connection wires into the clamps. For this purpose, the operating openings for the connection terminals are located at the terminal device which is operated from the rear in the upper part of the housing, and for operation from the front in the lower part of the housing.

Et utførelseseksempel på oppfinnelsen skal forklares nærmere under henvisning til tegningen. Fig. 1—5 viser en holder for skruebe-tjening fra forsiden. Fig. 6—10 viser en holder med skrue-betjening fra baksiden. Fig. 1 og 6 viser et grunnriss av dekslet. Fig. 2 og 7 viser et grunnriss av husunderdelen. Fig. 3 og 8 viser husunderdelen sett bakfra. Fig 4 og 9 viser et snitt langs linjen A—A resp. B—B. Fig. 5 og 10 viser perspektivisk kontakter for den ene eller den andre utfør-else. An embodiment of the invention will be explained in more detail with reference to the drawing. Fig. 1-5 shows a holder for screw operation from the front. Fig. 6-10 shows a holder with screw operation from the back. Fig. 1 and 6 show a plan view of the cover. Fig. 2 and 7 show a ground plan of the lower part of the house. Fig. 3 and 8 show the lower part of the housing seen from the rear. Figs 4 and 9 show a section along the line A—A resp. B—B. Fig. 5 and 10 show perspective contacts for one or the other design.

I husunderdelen 1 befinner det seg fire innleggsfordypninger la, lb, lc, ld, for de med kontaktene 3 forbundne tilslutningsklemmer 2. Innleggsfordypningene for tilslutningsklemmene er f. eks. anordnet i hjørnene av et rektangel, slik at alltid to innleggsfordypninger ligger diagonalt overfor hverandre. Ved bruk av starterholderen blir alltid to diagonalt overfor hverandre liggende innleggsfordypninger anvendt, nemlig for betjening fra forsiden-av huset innleggsfordypningene lb og ld,.og ved betjening fra baksiden innleggsfordypningene lc og la. Kontaktene 3 er som fig. 5 og 10 viser fremstilt av ett stykke og således forbundet med tilslutningsklemmene at de i det ene tilfelle for betjening fra forsiden er anbragt ved foten av klemmen, og i det annet tilfelle ved hodet av klemmen. Dette er nødvendig for at klemmene ved snudd innsetning, altså for betjening' fra baksiden, ellers ikke ville ligge an mot bunnen av husunderdelen. I de to husdeler befinner det seg for adkomst til klemskruene to hull le og lf i husoverdelen og lg og lh i husunderdelen. Hullene i de to husdeler ligger ikke rett over hverandre, men er for-delt på holderhusets fire hjørner. Dessuten er der boringer li og lk resp. 11 og" lm så-vel i husoverdelen som i husunderdelen for befestigelsesorganer, f. eks. hulnagler for å holde de to husdeler sammen. Innførings-åpningene 4a og 4b for kontaktstiftene befinner seg i husdekslet 4. Dessuten er der i sideveggene av husdelene åpninger ln, lo, lqu, av hvilke åpningene ln og lqu er anordnet i den nedre halvdel og lp og lo i den øvre halvdel av det samlede hus. In the lower part of the housing 1, there are four insert recesses la, lb, lc, ld, for the connection terminals 2 connected to the contacts 3. The insert recesses for the connection terminals are e.g. arranged in the corners of a rectangle, so that two insert recesses are always diagonally opposite each other. When using the starter holder, two diagonally opposite insert recesses are always used, namely for operation from the front of the housing insert recesses lb and ld, and for operation from the rear insert recesses lc and la. The contacts 3 are as fig. 5 and 10 show produced in one piece and thus connected to the connection clamps that in one case for operation from the front they are placed at the base of the clamp, and in the other case at the head of the clamp. This is necessary so that the clamps, when inserted upside down, i.e. for operation from the rear, would otherwise not rest against the bottom of the lower part of the housing. In the two housing parts, there are two holes le and lf in the upper housing part and lg and lh in the lower housing part for access to the clamping screws. The holes in the two housing parts do not lie directly above each other, but are distributed among the four corners of the holder housing. In addition, there are boreholes li and lk respectively. 11 and" lm both in the upper part of the housing and in the lower part of the housing for fasteners, e.g. hollow rivets to hold the two housing parts together. The insertion openings 4a and 4b for the contact pins are located in the housing cover 4. In addition, there are openings in the side walls of the housing parts ln, lo, lqu, of which the openings ln and lqu are arranged in the lower half and lp and lo in the upper half of the assembled housing.
