Description

Koiitaktfjærsats med minst en av ct drivorgan forskyvbar, Coiitakt spring set with at least one of the ct drive means displaceable,

bevegelig kontaktfjær. movable contact spring.

Oppfinnelsen angår en kontaktfj ær-sats, f. eks. for et elektromagnetisk relé, The invention relates to a contact spring set, e.g. for an electromagnetic relay,

hvor en med et kontaktlegeme forsynt, where one is provided with a contact body,

bevegelig kontaktfjær beveges ved hjelp av movable contact spring is moved by means of

et på tvers av fjærens plan forskyvbart, a transverse to the plane of the spring displaceable,

mellom kontaktlegemet og fjærens faststående ende angripende drivorgan. between the contact body and the fixed end of the spring attacking drive member.

Det har vist seg at som følge av kontaktlegemets massetreghet særlig når dette er utformet forholdsvis tungt f. eks. It has been shown that as a result of the mass inertia of the contact body, especially when this is designed relatively heavy, e.g.

dobbelt, slik som ved omkoplingskontakter double, as with change-over contacts

i sterkstrømsreléer, kan det bli utløst store in high-current relays, large currents can be tripped

krefter ved fjærens bevegelse, som kan forces by the movement of the spring, which can

føre til brudd av fjæren i nærheten av cause breakage of the spring in the vicinity of

drivorganets angrepspunkt. For å unngå the drive member's point of attack. To avoid

et slikt brudd kan den bevegelige kontaktfjær forsterkes, men dette har den ulempe such a break, the movable contact spring can be reinforced, but this has the disadvantage

at en større energi er nødvendig for en that a greater energy is necessary for one

like rask bevegelse av kontaktfjæren og en equally rapid movement of the contact spring and a

større kraft er nødvendig for å holde fjæren i den forskjøvne stilling. greater force is required to hold the spring in the offset position.

Hensikten med oppfinnelsen er å til-veiebringe en konstruksjon hvor brudd av The purpose of the invention is to provide a construction where breakage of

kontaktfjæren praktisk talt unngås uten at the contact spring is practically avoided without that

kontaktfj ærens f jærkarakteristikk med the contact spring's spring characteristic with

hensyn til tilbakestillingskraften påvirkes consideration of the reset force is affected

nevneverdig. Ifølge oppfinnelsen er den bevegelige fjærkontakt forsynt med en fjærstrimmel som strekker seg i kontaktfj ærens lengderetning gjennom drivorganet, significant. According to the invention, the movable spring contact is provided with a spring strip which extends in the longitudinal direction of the contact spring through the drive member,

mellom drivorganets angrepspunkt og fjæren, og som er forbundet med fjæren bare between the drive member's point of attack and the spring, and which is connected to the spring only

på en side av drivorganet, som ligger motsatt fjærens faste ende. Ved hjelp av denne strimmel opptas den ved kontaktlæ-rens bevegelse dannede bøyning slik at in- on one side of the drive member, which is opposite the fixed end of the spring. With the help of this strip, the bending caused by the movement of the contact leather is recorded so that in-

tet stedlig stort bøyemoment oppstår i fjæren. Kontaktfj ærens endestilling -leverer strimmelen tilbakestillingskraften. a locally large bending moment occurs in the spring. The end position of the contact spring - supplies the strip with the reset force.

Fortrinnsvis er strimmelen forbundet med fjæren på det sted kontaktlegemet er festet. Befestigelsen av strimmelen er i dette tilfelle enkel og kan skje samtidig med anbringelsen av kontaktlegemet. Preferably, the strip is connected to the spring at the point where the contact body is attached. The fastening of the strip is in this case simple and can take place simultaneously with the placement of the contact body.

Oppfinnelsen skal forklares nærmere The invention shall be explained in more detail

under henvisning til tegningen. with reference to the drawing.

Fig. 1 viser et lengdesnitt gjennom et utførclseseksempel på kontaktfj ærsatsen ifølge oppfinnelsen. Fig. 2 viser et snitt etter linjen II—II i fig. 1. Fig. 1 shows a longitudinal section through an embodiment of the contact spring set according to the invention. Fig. 2 shows a section along the line II—II in fig. 1.

På åket 1 av et bare delvis vist elektromagnetisk relé med et i enden av åket dreibart understøttet anker 2 er ved mel-lomlegg av isolasjonsstykket 3, festet en fjærsats med omkoplingskontakter. Fjær-satsen består av en forholdsvis stiv kontaktfjær 4 med et kontaktlegeme 5 i dens ende, en bevegelig kontaktfjær 6 med et dobbelt kontaktlegeme 7 i dennes ende og en annen forholdsvis stiv kontaktfjær 8 med et kontaktlegeme 9. Den bevegelige kontaktfjær 6 ligger i ankerets hvilestilling med den undre del av kontaktlegemet 7 under påvirkning av sin egen forspenning an mot kontaktlegemet 5 på dens undre fjær 4. On the yoke 1 of an only partially shown electromagnetic relay with an armature 2 rotatably supported at the end of the yoke, a spring set with switching contacts is attached by overlapping the insulation piece 3. The spring set consists of a relatively rigid contact spring 4 with a contact body 5 at its end, a movable contact spring 6 with a double contact body 7 at its end and another relatively rigid contact spring 8 with a contact body 9. The movable contact spring 6 is in the anchor's rest position with the lower part of the contact body 7 under the influence of its own bias against the contact body 5 on its lower spring 4.

Til ankeret 2 er koplet et drivorgan 10 i form av en stige, som ved bevegelse av ankeret ved reléets energisering, beveger seg oppover på tvers av kontaktfj ærenes plan. Drivorganet 10 holdes i oppreist stilling ved hjelp av en åpning 13 som fjæren. 14 er ført gjennom, og som sammen med kontaktfjærene 4, 6 og 8 er festet til åket 1. Ved bevegelse av drivorganet 10 ut av den stilling som er vist i fig. 1, bringer et tverr-steg 11 på drivorganet kontaktfjæren 6 i en stilling i hvilken den øvre del av kontaktlegemet 7 kommer i berøring med kontaktlegemet 9 på den øverste kontaktfjær 8, mens kontakten mellom kontaktlegemet 7 og den undre kontaktfjær 4 brytes. På undersiden av den bevegelige kontaktfjær 6 er anordnet en bøyelig metallstrimmel 12, som på det sted kontaktlegemet 7 er festet, er forbundet med fjæren 6 og strekker seg mellom denne fjær og tverrsteget 11 på drivorganet 10. I ankerets hvilestilling er der mellom strimmelen 12 og tverrsteget 11 på drivorganet, en viss klaring slik at kontakttrykket mellom kontaktle-gemene 5 og 7 utelukkende er betinget av forspenningen i fjæren 6. Ved energisering av reléet når tverrsteget 11 fjærstrimmelen 12 med en viss hastighet, idet fjæren 6 meddeles et støt. Da kontaktlegemet 7 har en forholdsvis stor masse, ville fjæren 6 uten strimmelen 12 bøyes sterkt. Bøyningen av fjæren 6 opptas imidlertid mer eller mindre av strimmelen 12, slik at det ikke dannes noen stor lokal konsentrasjon av den mekaniske spenning i kontaktfjæren 6. Strimmelen 12 påvirker i endestillingen ikke den på driv organet 10 utøvede tilbakestillingskraft eller bare i liten grad idet kontaktfj ærens ettergivenhet er bestemmende. Strimmelen 12 har dessuten den fordel at dennes frik-sjon med fjæren 6 minsker kontaktlegemets 7 tilbøyelighet til å slå tilbake, når den bringes i berøring med den øvre fjær. A drive member 10 in the form of a ladder is connected to the armature 2, which, when the armature is moved when the relay is energized, moves upwards across the plane of the contact springs. The drive member 10 is held in an upright position by means of an opening 13 as the spring. 14 is passed through, and which, together with the contact springs 4, 6 and 8, is attached to the yoke 1. When moving the drive member 10 out of the position shown in fig. 1, a transverse step 11 on the drive member brings the contact spring 6 into a position in which the upper part of the contact body 7 comes into contact with the contact body 9 of the upper contact spring 8, while the contact between the contact body 7 and the lower contact spring 4 is broken. On the underside of the movable contact spring 6, a flexible metal strip 12 is arranged, which, at the point where the contact body 7 is attached, is connected to the spring 6 and extends between this spring and the cross step 11 of the drive member 10. In the armature's rest position, there is between the strip 12 and the cross step 11 on the drive member, a certain clearance so that the contact pressure between the contact bodies 5 and 7 is solely conditioned by the bias in the spring 6. When the relay is energized, the cross step 11 reaches the spring strip 12 with a certain speed, the spring 6 being given a shock. As the contact body 7 has a relatively large mass, the spring 6 without the strip 12 would bend strongly. The bending of the spring 6 is, however, more or less taken up by the strip 12, so that no large local concentration of the mechanical tension is formed in the contact spring 6. The strip 12 does not affect the drive in the end position the body 10 exerted a restoring force or only to a small extent, as the compliance of the contact spring is decisive. The strip 12 also has the advantage that its friction with the spring 6 reduces the tendency of the contact body 7 to strike back when it is brought into contact with the upper spring.
