Udløsemekanismen består af et magnetåg med en plan anlægsdel, et bort derfra vinkelret bøjet vinkelben forsynet med en spole og et andet ben og desuden en permanentmag- 15 net. Derved tjener huset ikke kun som beskyttelse, men kommer også til at fungere som en del af udløsemekanismen, hvorved der via huset kan optræde mekaniske spændinger fra magnetsystemet.DE patent patent No. 20 29 607 discloses a housing enclosed in a cover and a base plate, 10 sensitive permanent magnetic release mechanism for fault current relays and similar appliances. The release mechanism consists of a magnetic yoke with a flat abutment portion, an angular leg bent away from it, provided with a coil and a second leg, and in addition a permanent magnet. In this way, the housing not only serves as protection, but also functions as part of the release mechanism, whereby mechanical stresses from the magnetic system can occur via the housing.

20 Endvidere er det fra DE offentliggørelsesskrift nr.20 Furthermore, from DE publication no.

20 00 138 kendt at udstyre en magnetkerne med fastgørelsesorganer til bærefladen og at fastgøre permanentmagneten til det andet vinkelben.20 00 138 is known to equip a magnetic core with fastening means for the support surface and to attach the permanent magnet to the second angular leg.

25 Desuden er det fra AT patentskrift nr. 2 66 972 kendt at fastgøre en holdeplade på magnetkernen, hvilken holdeplade samtidigt tjener som lejring for ankeret og som ophængning for ankerfjederen.25 Furthermore, it is known from AT Patent Specification No. 2,667,972 to attach a retaining plate to the magnetic core, which simultaneously serves as a bearing for the anchor and as a suspension for the anchor spring.

30 Opfindelsens formål er at angive en permanentmagnetisk udløsemekanisme, især til fejlstrømsrelæer, som har en stor følsomhed, og som har små dimensioner og få enkeltdele, som er enkle at montere og som ved ydre påvirkninger begrænser ændringerne i udløservær-The object of the invention is to provide a permanent magnetic release mechanism, especially for fault current relays which have a high sensitivity, which have small dimensions and few single parts which are easy to assemble and which, by external influences, limit the changes in the output value.

2 dierne til et absolut minimum.2 dies to an absolute minimum.

Dette opnås ved at udforme udløsemekanismen ifølge opfindelsen som angivet i krav l's kendetegnende del.This is achieved by designing the release mechanism of the invention as set forth in the characterizing portion of claim 1.

55

Ifølge opfindelsen kan udløsemekanismen være fastgjort i huset som nærmere angivet i krav 2's kendetegnende del. Huset er fortrinsvis udformet som en sprøjtestøbt del med lejring af magnetågets fastgø-10 relsesfremspring mellem anlægssteder ved fodenden af dækslet og bundpladen, der er tæt sammensvejset, f.eks. med ultralyd.According to the invention, the release mechanism may be fixed in the housing as further specified in the characterizing part of claim 2. The housing is preferably formed as an injection molded part with the bearing of the magnet train attachment protrusion between abutment sites at the foot end of the cover and the bottom plate which are tightly welded, e.g. with ultrasound.

Opfindelsens grundtanke ligger i at montere udløseor-15 ganets funktionsdele neutralt i huset og indbyrdes.The basic idea of the invention lies in mounting the functional parts of the triggering body neutral in the housing and mutually.

Spændinger i huset på grund af temperatursvingninger, fastgørelser ved hjælp af skruer og andre påvirkninger kan ikke ved lejring på et enkelt sted eller ved ophængning af magnetåget i huset, overføres til det-20 te, og herved heller ikke til ankerets lejring eller dets belastningsfjeder.Tensions in the housing due to temperature fluctuations, fasteners by screws and other stresses cannot be transmitted to this unit by mounting in a single location or by hanging the magnetic yoke in the housing, and neither to the anchor bearing nor its load spring.

I det følgende forklares opfindelsen nærmere under henvisning til tegningen, hvor 25 fig. 1 viser et længdesnit gennem en udførelsesform for en udløsemekanisme ifølge opfindelsen, fig. 2 viser et tværsnit gennem udløsemekanismen ef-30 ter linien A-A i fig. 1, fig. 3 viser et snit gennem udløsemekanismen efter linien B~B i fig. 1 ogBRIEF DESCRIPTION OF THE DRAWINGS In the following, the invention is explained in more detail with reference to the drawing, in which FIG. 1 is a longitudinal section through an embodiment of a release mechanism according to the invention; FIG. 2 shows a cross section through the release mechanism along line A-A in FIG. 1, FIG. 3 shows a section through the release mechanism along the line B ~ B in FIG. 1 and

3 fig. 4 viser et snit i fig. 1 efter linien C-C* og visende indspændingen af udløsemekanismens magnetåg i huset.3 FIG. 4 is a sectional view of FIG. 1 along line C-C * and showing the clamping of the release mechanism's magnetic shaft in the housing.

5 Den på tegningen viste permanentmagnetiske udløsemekanisme består af et magnetåg 1, en på denne fastgjort permanent magnet 2, en på magnetågets ene ben 3 monteret udløsespole 4, et klapanker 5, en belastningsfjeder 6 for klapankeret og en af klapankeret 10 betjent tap eller stødstang 7 til udløsning af en klinke eller lignende. Til montering af permanentmagneten 2 på magnetåget tjener en elastisk holdeplade 8 og en nitte 9 eller lignende organer. Fra holdepladen er der udbøjet en lap eller et fremspring 10 med et 15 hul 11 til indhægtning af fjederen 6, og endvidere er der udformet et gaffelorgan 12 til fastholdelse og lejring af klapankerets 5 knivleje 13. Holdepladen 8 ligger under let forspænding an mod magnetåget 1, hvorved det er muligt at foretage en toleranceudlig-20 ning for lejringen. Udløsemekanismen er indbygget i et hus bestående af en bundplade 14 og et dæksel 15 med gennemgangsåbning 16 for tappen 7. Til tætning af lysningen eller spalten mellem tappen 7 og randen af gennemgangsåbningen 16 tjener en dækplade 17 af et 25 ældningsstabilt, højelastisk materiale, f.eks. sili-conegummi med en membran 17 med en tykkelse på under 0,1 mm. Til fastgørelse af magnetåget i huset har magnetåget 1 på en side en kort, lige anlægsdel 18 med fastgørelsesfremspring 10. Den korte anlægsdel 18 30 med fremspringene 19 er indført mellem fodenden af dækslet 15 og bundpladen 14, og dækslet 15 og bundpladen 14 er indbyrdes sammensvejset med ultralyd.5 The permanent magnetic release mechanism shown in the drawing consists of a magnetic yoke 1, a permanent magnet 2 attached to it, a release coil 4 mounted on one of the magnetic yoke 3, a flap anchor 5, a load spring 6 for the flap anchor and a pin or thrust rod operated by the flap 10. for triggering a latch or the like. For mounting the permanent magnet 2 on the magnetic train, an elastic retaining plate 8 and a rivet 9 or similar means are used. From the retaining plate, a patch or projection 10 is provided with a 15 hole 11 for securing the spring 6, and furthermore a fork member 12 is provided for holding and locking the knife bearing 13 of the anchor 5. The retaining plate 8 lies under light bias against the magnetic train 1 , thereby allowing a tolerance equalization for the bearing. The release mechanism is built into a housing consisting of a base plate 14 and a cover 15 with passage opening 16 for the pin 7. For sealing the gap or gap between the pin 7 and the rim of the passage opening 16, a cover plate 17 of a 25 aging-resistant, high elastic material, f. eg. silicone rubber having a membrane 17 with a thickness of less than 0.1 mm. For fastening the magnetic yoke in the housing, the magnetic yoke 1 has on one side a short, straight abutment portion 18 with attachment protrusions 10. The short abutment portion 18 30 with the projections 19 is inserted between the foot end of the cover 15 and the base plate 14, and the cover 15 and the base plate 14 are mutually welded together. with ultrasound.

punktet, og belastningsfjederén 6 er ophængt i en vinkel, der er større end 90° i forhold til ankeret 5. Fjederophængningen med gaffellejringen sikrer fastholdelsen af klapankeret på magnetåget 1 uden 5 ekstra organer.the point and the load spring 6 is suspended at an angle greater than 90 ° to the anchor 5. The spring suspension with the fork bearing ensures the retaining of the anchor on the magnet shaft 1 without 5 additional means.

Den væsentligste fordel ved udløsemekanismen ifølge opfindelsen ligger i, at de i huset, på grund af tryk- og temperaturpåvirkninger, opståede spændinger 10 som følge af den ensidige ophængning af udløseren i huset ikke overføres til magnetåget. Udløseorganerne påvirkes derfor ikke, og udløserværdiernes spredning kan derfor holdes inden for snævre grænser.The main advantage of the release mechanism according to the invention lies in the fact that the stresses 10 caused by the unilateral suspension of the trigger in the housing due to pressure and temperature effects are not transferred to the magnetic train. The trigger means are therefore not affected and the spread of the trigger values can therefore be kept within narrow limits.
