Description

Kontaktklemme for ledninger i elektrisk Contact clamp for wires in electrical

installasjonsmateriell. installation material.

Foreliggende oppfinnelse angår en kontakMemme for ledninger i elektrisk installasjonsmateriell, og som er av den type hvori minst en ledningsende kan klemmes mellom en kontaktplate og en spent fjær, som ved åpning av klemmen forskyves bort fra platen for innsetning eller uttagning av vedkommende ledningsende. The present invention relates to a contact memory for wires in electrical installation material, and which is of the type in which at least one wire end can be clamped between a contact plate and a tensioned spring, which, when the clamp is opened, is moved away from the plate for insertion or removal of the wire end in question.

Sådanne klemmer anvendes fortrinnsvis i vanlig elektrisk installasjonsmateriell som brytere, stikkontakter, stopsler, kontaktbokser og lignende. Such clamps are preferably used in ordinary electrical installation material such as switches, sockets, plugs, contact boxes and the like.

Åpning og lukning av klemmen skjer vanligvis ved hjelp av en trykkanordning, f.eks. en trykknapp, som virker mer eller mindre direkte på fjæren. Et betydelig trykk må herunder utoves ved. manovrering av fjæren, da denne må være forholdsvis stiv for å Opening and closing of the clamp is usually done by means of a pressure device, e.g. a push button, which acts more or less directly on the spring. Considerable pressure must be exerted here. maneuvering of the spring, as this must be relatively stiff in order to

gi godt kontakttrykk. Slike trykkanordninger er derfor ubekvemme i bruk, og krever trykkfjærer av forholdsvis dyr utforelse og provide good contact pressure. Such pressure devices are therefore inconvenient to use, and require pressure springs of a relatively expensive design and

komplisert oppbygning. complicated structure.

Det er derfor oppfinnelsens hovedformål å fremskaffe en anordning for åpning og lukning av kontaktklemmer av foreliggende type, og som er konstruert slik at de ovenfor angitte ulemper unngås. It is therefore the main purpose of the invention to provide a device for opening and closing contact terminals of the present type, and which is constructed so that the above-mentioned disadvantages are avoided.

Dette oppnås i henhold til oppfinnelsen ved at en ekssenterskrve This is achieved according to the invention by an eccentric screw

er slik dreibart anordnet i forhold til fjæren at skiven i en fbrste vinkelstilling ikke påvirker fjæren, men ved dreining til en annen vinkelstilling forskyver fjæren bort fra kontaktplaten for åpning av klemmen. is so rotatably arranged in relation to the spring that the disc in a first angular position does not affect the spring, but when turned to another angular position, the spring moves away from the contact plate to open the clamp.

Herved oppnås en særskilt enkel utforelse med et nedsatt antall nodvendige deler, og som gjor det mulig å minske anordningens dimensjoner, samtidig som anordningen er lett manovrerbar fra siden av kontaktklemmen, spesielt hvis ekssenterskiven, i henhold til oppfinnelsen, er forsynt med et spor for dreining av skiven ved hjelp av en skrutrekker eller lignende. In this way, a particularly simple design is achieved with a reduced number of necessary parts, and which makes it possible to reduce the device's dimensions, while the device is easily maneuverable from the side of the contact clamp, especially if the eccentric disk, according to the invention, is provided with a groove for turning off the disc using a screwdriver or similar.

Oppfinnelsen vil nå bli nærmere forklart ved hjelp av et utforelseseksempel og under henvisning til vedfoyde tegninger, der Fig.. 1 viser, sett. fra siden, en vippebryter med kontakikLemmer i henhold til oppfinnelsen; The invention will now be explained in more detail by means of an embodiment example and with reference to the attached drawings, where Fig. 1 shows, set. from the side, a rocker switch with contactor Limbs according to the invention;

Fig. 1a viser et utsnitt'av fig. 1, der klemmen er vist stiplet Fig. 1a shows a section of fig. 1, where the clamp is shown dashed

i åpen stilling; Fig. 2 viser bryteren i fig. 1 sett ovenfra og i snitt langs linjen II-II i fig. 1, og Fig. 3 viser et tverrsnitt gjennom bryteren i fig. 1, delvis langs linjen IIIA-IIIA og delvis langs linjen IIIB-IIIB i denne figur. in open position; Fig. 2 shows the switch in fig. 1 seen from above and in section along the line II-II in fig. 1, and Fig. 3 shows a cross-section through the switch in Fig. 1, partly along the line IIIA-IIIA and partly along the line IIIB-IIIB in this figure.

En vippebryter av den type som er vist i figurene er utformet for å kobles direkte inn i en tilkoblingsledning for en lampe eller lignende, og for å bæres opphengt i denne ledning. A rocker switch of the type shown in the figures is designed to be plugged directly into a connecting wire for a lamp or the like, and to be carried suspended in this wire.

I fig. 1 er bryteren vist med borttatt ytterdeksel på den ene langside, og til venstre i figuren, i snitt gjennom lengdeaksen. Til hoyre for midten er det vist en kontaktklemme i henhold til oppfinnelsen med en krum bladfjær 1 som ved sin ytterende 1a ligger an mot en kontaktplate 2. Ved dreining av en ekssenterskive 3, som er anordnet dreibart om en akse 3a gjennom skivens overste del, med urviseren, vil skiven skyve anleggsenden 1a, av den krumme bladfjær bort fra kontåktplaten 2. Herved fremkommer den stilling av ekssenterskiven 3 og bladfjæren 1 som er vist stiplet i fig. 1a, og som tilsvarer åpen stilling for kontaktklemmen. Ved at ekssenterskiven i denne stilling ligger an mot bakveggen 8, og kraften fra bladfjæren angriper til venstre for dreieaksen 3a, er klemmens åpne stilling gjort stabil. I denne stilling kan, som antydet i fig. 1a, en avisolert ledningsende L innfores bak ekssenterskiven 3 mellom kontåktplaten og bladfjæren. Ved dreining av ekssenterskiven tilbake til utgangsstillingen frigjores bladfjæren 1 og presser ledningsenden L mot kontåktplaten 2, i lukket stilling av kontaktklemmen. In fig. 1, the switch is shown with the outer cover removed on one long side, and on the left in the figure, in section through the longitudinal axis. To the right of the center is shown a contact clamp according to the invention with a curved leaf spring 1 which at its outer end 1a rests against a contact plate 2. When turning an eccentric disc 3, which is arranged to be rotatable about an axis 3a through the top part of the disc, clockwise, the disk will push the contact end 1a of the curved leaf spring away from the contact plate 2. This results in the position of the eccentric disk 3 and the leaf spring 1 which is shown dashed in fig. 1a, and which corresponds to the open position for the contact terminal. As the eccentric disk in this position rests against the rear wall 8, and the force from the leaf spring acts to the left of the axis of rotation 3a, the clamp's open position is made stable. In this position, as indicated in fig. 1a, a stripped cable end L is inserted behind the eccentric disk 3 between the contact plate and the leaf spring. When turning the eccentric disc back to the starting position, the leaf spring 1 is released and presses the cable end L against the contact plate 2, in the closed position of the contact clamp.

Plasseringen av bladfjæren 1 og kontåktplaten 2 i forhold til ekssenterskiven 3 ef nærmere vist i fig. 2 og 3» Som det vil fremgå av disse figurer, der kontaktklemmen liksom i fig. 1 er vist i lukket stilling, er bladfjæren så bred at det er god plass til innforing av minst en ledningsende innenfor ekssenterskiven, for fastklemning mellom fjæren og platen. Som det vil fremgå av fig. 1 er en lignende,kontaktklemme anordnet på den annen side av bryterens tversgående symmetriplan, og som antydet i fig. 2 og 3, er to tilsvarende klemmer også plassert på motsatt side av bryterens langsgående symmetriplan. Ekssenterskivene for disse fire klemmer er parvis forenet over en mellomliggende tversgående aksel k- som er dreibar om vedkommende ekssenterskivers felles akse 3a. De to skiver 3 som befinner seg på samme aksel h, kan således dreies synkront ved innforing av f.eks. en skrutrekker i et av de spor 3b som er utformet på yttersiden av hver ekssenterskive 3. The location of the leaf spring 1 and contact plate 2 in relation to the eccentric disk 3 ef is shown in more detail in fig. 2 and 3" As will appear from these figures, where the contact clamp as in fig. 1 is shown in the closed position, the leaf spring is so wide that there is plenty of room for inserting at least one wire end inside the eccentric disk, for clamping between the spring and the plate. As will be seen from fig. 1 is a similar contact clamp arranged on the other side of the switch's transverse plane of symmetry, and as indicated in fig. 2 and 3, two corresponding clamps are also located on the opposite side of the switch's longitudinal plane of symmetry. The eccentric discs for these four clamps are united in pairs over an intermediate transverse shaft k- which is rotatable about the respective eccentric disc's common axis 3a. The two discs 3 which are located on the same shaft h can thus be turned synchronously by inserting e.g. a screwdriver in one of the grooves 3b which are designed on the outside of each eccentric disc 3.

En toleder med adskilte og avisolerte ledningsender kan innfores A two-wire with separated and stripped wire ends can be inserted

fra hver ende av bryteren gjennom hull 5 og fremforingskanaler 6, from each end of the switch through holes 5 and feed channels 6,

slik at nevnte ledningsender L fores på hver sin side av en skillevegg 7 (fig. 2) og inn i .mellomrommet mellom bladfjær 1 og kontaktplate'2 for hver sin kontaktklemme i vedkommende klemmepar med felles ekssenterakse når de to kontaktklemmer befinner seg i åpen stilling, slik som antydet stiplet i fig. 1a. so that said wire ends L are fed on each side of a partition 7 (fig. 2) and into the space between leaf spring 1 and contact plate'2 for each contact clamp in the relevant clamp pair with a common eccentric axis when the two contact clamps are in the open position , as indicated by the dotted line in fig. 1a.

Resten av bryteren er stort sett av konvensjonell utforelse, og The rest of the switch is mostly of conventional design, and

vil. ikke bli beskrevet i detalj her. Det skal bare ganske kort antydes at kontaktbrytningen og -slutningen foregår ved hjelp av en vippeknast V som er anordnet omtrent i bryterens langsgående want. not be described in detail here. It should only be briefly mentioned that the contact breaking and closing takes place with the help of a toggle cam V which is arranged approximately in the longitudinal direction of the switch

symmetriplan. Denne vippeknast påvirker en kontaktåive S, som i knastens ene stilling danner kontakt mellom kontaktplatene 2 i kontaktklemmene på bryterens 1 ene langside. I vippeknastens annen stilling oppheves denne kontakt, således at strømforsyningen over vedkommende tilkoblingsledning opphorer. plane of symmetry. This toggle cam affects a contact force S, which in one position of the cam forms contact between the contact plates 2 in the contact clamps on one long side of the switch 1. In the other position of the toggle cam, this contact is canceled, so that the power supply via the relevant connection cable ceases.

På den annen langside av bryteren er kontaktklemmenes kontaktplater On the other long side of the switch are the contact plates of the contact terminals

permanent kortsluttet, idet det er anordnet en felles.kontaktplate ha. Bryteren er således innrettet for enpolet brytning og slutning. permanently short-circuited, since a common contact plate has been arranged. The switch is thus designed for single-pole breaking and closing.
