Description

Uppfinnare: H Prien och H-S Wulff Priorttet beglird frau den 18 juni 1959 (Forbundsrepubliken Tyskland) Uppfinningen avser en elektrisk effektbrytare for lagspanining med kopplingslas och svangbar kontaktbdrare, I vilken de rorliga kontaktstyckena aro ledbart insatta och vid vilken varje rorligt kontaktstyeke pkverkas av em fjdderkraftsackum:ulator, vilken med sin frau, kontaktstyeket vanda ande stoder mot den fasta brytard.elen. Inventors: H Prien and HS Wulff Priorttet Beglird frau June 18, 1959 (Federal Republic of Germany) ulator, which with its wife, the contact piece of water ande stands against the fixed switch.

Till .grund fOr uppfinningen ligger uppglften aft Ora de i kontaktbararen insatta kontaktstyckena latt uthytbara. The basis for the invention is the object of making the contact pieces inserted in the contact bar easily removable.

I enlighet med uppfinningen uppvisa:r den svangbara kontaktbararen for laming av denna uppgift for varje kontaktstycke tvd urtag, vilkas langdaxlar bilda rat vinkel med varandra ooh i vilka dot i varje fall iirdgavarande kontaktstycket samt ett anslutnings stycke for forbindning av det rorliga kontaktstycket med tilledningen Ore lost insatta samt genom fjaderkraftackumulatorn kraftbundet f8rbundna med varandra. In accordance with the invention, the pivotable contact carrier for laminating this object has two recesses for each contact piece, the longitudinal axes of which form an angled distance with each other and in which at least the respective contact piece and a connecting piece for connecting the movable contact piece to the conductor Ore loosely inserted and through the spring force accumulator forcibly connected to each other.

Ytterligare kannetecken p5 uppfinningen fraingd av beskrivningen av ett utfoiingsexempel. Pd. ritningen Or ett utfOringsexempel ,enligt uppfinningen askadliggjort. PA densamma visar fig. 1 en flerpolig effektbrytare i sidovy och genomskarning; fig. 2 ett rorligt kontaktstycke rned anslutningsstycke oh klambygel i perspektiv och i isardraget skiek. Further features of the invention may be derived from the description of an exemplary embodiment. Pd. drawing Or an exemplary embodiment, according to the invention disassembled. PA the same, Fig. 1 shows a multipole circuit breaker in side view and section; Fig. 2 shows a movable contact piece with a connecting piece and clamp in perspective and in the ice-drawn skiek.

I det sektionerade isolermaterialholjet 1 Or den svangbara kontaktbararen 2 exeentriskt lagrad. Kopplingsldset, vilket paverkar kontaktbararen, dr icke dskddliggjort. Kontaktbdraren 2 Or fOr varje kontaktstyeke 5 fOrsedd med tvenne urtag 3 ooh 4, vilkas langdaxtar Oro vinkelrata mot varandra. In the sectioned insulating material casing 1 Or the pivotable contact carrier 2 is eccentrically stored. The coupling lead, which affects the contact bar, is not damaged. The contact carrier 2 Or for each contact piece 5 provided with two recesses 3 and 4, the long axes of which are perpendicular to each other.

Kontaktstyeket Or i kontaktbdraren 2 vridbart lagrat ouakring axeln 6. The contact piece Or in the contact carrier 2 rotatably mounted without the shaft 6.

I urtagen 3 och 4 Oro kontaktstycket 5 och anslutningsstycket 7 med klambygeln 8 lost insatta. Fjdderkraftackurnulatorn 9., vilken vilar mot holjessoekeln, trycker anslutningsstycket 7, vilket genom punktsvetsning Ar fOrbundet med den bojliga tilledningen 11, fast mot kontaktstyeket 5. Klambygeln 8, vilken dessutom Miler kontaktstycket 5 i kraftlaunder', forbindelse med anslutningsstycket 7, sailer for att kontaktstyeket 5 Or sdkert anorduat pd. anslutningsstycket 7 orb 'War dessutom kontakttrycket. Stallskruven tjanar for ins-Wining av kontakttrycket. Fja.- derkraftackumulatarn 9 astral-, dels det erforderliga kontakttrycket mellan kontaktstycke 5 och anslutningsstycke 7, dels alstrar den kontakttrycket mellan det fasta och dot rOrliga kontaktstycket oak tjdnar vidare som atertrycksfjader for den svdngbara kontaktbdraren 2, di brytaren oppnas, dvs. nOr lasningea av det joke dskadliggjorda kopplingsbasot lossas. In the recesses 3 and 4, make sure that the contact piece 5 and the connecting piece 7 with the clamp bracket 8 are inserted loosely. The spring force accumulator 9, which rests against the hollow base, presses the connecting piece 7, which by spot welding is connected to the flexible conduit 11, fixedly to the contact piece 5. The clamp bracket 8, which in addition Miles the contact piece 5 in kraftlaunder ', connects to the connecting piece 7, 5 Or sdkert anorduat pd. the connection piece 7 orb 'War also the contact pressure. The stable screw serves for ins-Wining of the contact pressure. The spring accumulator 9 is astral, on the one hand the required contact pressure between contact piece 5 and connection piece 7, and on the other hand it generates the contact pressure between the fixed and double contact piece which also serves as a return pressure spring for the pivotable contact carrier 2, in which the switch is opened. nOr lasningea of the joke damaged clutch bassot is loosened.

For .utbyte av kontaktstyckena bringas kontaktbdraren 2 till oppningslage. Kontaktstycket 5 kan sedan latt dragas nit framdt ur kontaktbararen 2 och ersattas med ett nytt kontaktstycke, vilket hell enkelt skjutes in kontaktbdraren. Varje kontaktstycke 5 liar ett urtag 12, med vilket det vid inskjutandet mellan klambygeln 8 och anslutningsstycke 7 bringas i ingrepp. Efter utdragande av anslutningsstycket och avlagsnande av mnst011- nimgsskruvenJ 10 kan aven anslutningsstycket 7 oak anslutningsbandet 11 utbytas. To replace the contact pieces, the contact carrier 2 is brought to the opening position. The contact piece 5 can then be easily pulled riveted forward from the contact carrier 2 and replaced with a new contact piece, which is easily easily pushed into the contact carrier. Each contact piece 5 has a recess 12, with which it is brought into engagement when inserted between the clamping bracket 8 and the connecting piece 7. After pulling out the connecting piece and removing the mandrel screw 10, the connecting piece 7 and the connecting band 11 can also be replaced.

Claims

Patent claim:

1. An electrical circuit breaker with a pivotable contactor, in which the movable contactors are articulated and in which 2— - each movable contactor is actuated by a spring force.curulator, which with its. Iran's contact with the spirit is resting against it. the fixed breaking part, characterized therefrom, by the pivotable contact carrier, which partly comprises the movable contact pieces, has two recesses, the long axes of which are perpendicular to each other, in which the rotary contact piece and a connecting piece for connecting the movable contact piece to the supply. aro lost inserted oh through the spring force accumulator the power dog united with each other.

2. An electrical circuit breaker according to claim 1, characterized in that the movable connector also passes through a. elastic clamp is the power dog joined to the connecting piece.

3. An electrical circuit breaker according to claim 1 or 2, characterized therefrom, by the connection force with the movable contact piece forcibly coupling the spring. in addition, the contact pressure between the fixed oth (slightly strange contact piece) also creates such contact tapping springs on the contact bar when the strange contact piece locking the coupling load is released.
