DK 161923 BDK 161923 B

Opfindelsen angår en elektrisk sikringsindsats, især en lavspæn-dings-højeffektsikringsindsats med et rørformet hus af isolationsmateriale, hvis kontaktkniv og smelteleder er indført aksialt og ligger med fremspring fra kontaktkniven på en rand af huset, hvorhos tilslutnings-5 plader fastholder kontaktkniven.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an electrical fuse insert, in particular a low-voltage, high-power fuse insert, with a tubular housing of insulating material, the contact knife and melt conductor being axially inserted and projecting from the contact knife onto an edge of the housing where the connecting plate retains the contact knife.

For at opnå en høj mekaniseringsgrad ved montagen, undgås gerne skrue- og svejseforbindelser, som kræver megen tid.To achieve a high degree of mechanization during assembly, screw and weld joints are required, which require a lot of time.

Der kendes en smeltesikring (DE-patentskrift 16 38 141), som består af et rørformet hus af isolationsmateriale med påmonterede dækpla-10 der. En præfabrikeret enhed af to kontaktknive og en smelteleder, som forbinder disse, føres ind i det rørfomede hus og fastlåses. Herved forhindrer en ved basis af en kontaktkniv anbragt knopformet forbindelse en udtrækning af smeltelederen fra huset. Kontaktkniven forskydes få millimeter radialt udad, således at en på den anbragt næse ligger kne-15 bent på husranden. På den overfor liggende side af kontaktkniven griber en af husets dækplader ind i en udsparing i kontaktkniven. Således forhindres det, at kontaktkniven glider tilbage ind i husets indre. Herunder er det ganske vist nødvendigt, at kontaktkniven og husets dækplade monteres i én arbejdsgang.A melt fuse is known (DE patent 16 38 141), which consists of a tubular housing of insulating material with mounted cover plates 10. A prefabricated unit of two contact blades and a melting conductor connecting them is inserted into the tubular housing and locked. Hereby a knob-shaped connection arranged at the base of a contact knife prevents the extraction of the melt conductor from the housing. The contact knife is displaced a few millimeters radially outwards so that one on the positioned nose lies squarely on the edge of the housing. On the opposite side of the contact knife, one of the cover plates of the housing engages in a recess in the contact knife. Thus, the contact knife is prevented from sliding back into the interior of the housing. It is, of course, necessary that the contact knife and the cover plate of the housing be mounted in one workflow.

20 Ved en anden kendt sikringsindsats (US-patentskrift 1.790.713) ligger et bundt af smelteledere med kontaktknive på begge ender efter en radial forskydning inde i et hus på skuldrene af tilslutningskappen.In another known fuse insert (U.S. Pat. No. 1,790,713), a bundle of melt conductors with contact blades is located on both ends following a radial displacement inside a housing on the shoulders of the connection sheath.

Skuldrene strækker sig her i samme plan som smeltelederne.The shoulders extend here in the same plane as the melting conductors.

Til grund for opfindelsen ligger den opgave at udvikle en lavspæn-25 dings-højeffekt sikringsindsats, hvor arreteringen af kontaktkniven ved huset forbedres samtidig med at montagen af kontaktkniven forenkles.The object of the invention lies in the development of a low-voltage high-power fuse in which the arrangement of the contact knife at the housing is improved while simplifying the mounting of the contact knife.

Denne opgave løses ifølge opfindelsen ved hjælp af en sikring ifølge krav 1 med de kendetegnende ejendommeligheder.This task is solved according to the invention by means of a fuse according to claim 1 with the characteristic features.

Ifølge krav 1 har en første endeplade ved basis af en første kontakt-30 kniv udformninger, som griber ind i tilsvarende modsatte udformninger i huset. Efter indføringen af enheden bestående af kontaktkniv, endeplade og smelteleder forskydes den første kontaktkniv radialt således, at den første endeplade kan støtte sig mod fx. en rippe og på hvileflader, som findes i åbningen i huset. Denne konstruktion forhindrer en tilbage-35 glidning ind i husets indre. Derefter kan afslutningspladerne, som - 2 -According to claim 1, a first end plate at the base of a first contact knife has configurations which engage in correspondingly opposite configurations in the housing. After the insertion of the unit consisting of contact knife, end plate and melting conductor, the first contact knife is radially displaced so that the first end plate can withstand e.g. a ripping and resting surface which is found in the opening in the house. This construction prevents back sliding into the interior of the housing. Then, the end plates which - 2 -

trykker endepladerne mod hvilefladerne, skrues på husets endeflade.pushing the end plates against the resting surfaces, screw on the end surface of the housing.

Derved er den første kontaktkniv sikret mod udløftning og fast arrete-ret.Thereby the first contact knife is secured against lifting and fixed arrests.

En anden endeplade ved basis for den anden kontaktkniv, som ligger 5 over for den første kontaktkniv, er udformet med udsparinger således, at den allerede ved en centreret position ligger på hvileflader i hu set. Dette mliggør en yderligere forenkling af konstruktionen.A second end plate at the base of the second contact knife, which is 5 opposite the first contact knife, is designed with recesses so that it is already at a centered position on the resting surface of the housing. This allows for further simplification of the construction.

Den anden endeplade ved basis af den anden kontaktkniv kan være udformet så bred, at den hviler på en ringformet hvileflade i huset.The second end plate at the base of the second contact knife may be formed so wide that it rests on an annular resting surface in the housing.

10 Herved kan man anvende et hus uden ripper, hvilket letter husfremstillingen og tillader en hurtigere og lettere indføring af konstruktionsenheden bestående af kontaktknive og smelteledere. Herunder forhindres tilbageglidningen af en kontaktkniv ind i huset ved, at der i udsparingerne i husets endeflader er indlagt mindst én stift, på hvilken den 15 anden endeplade ved basis for den anden kontaktkniv i huset allerede ligger i en centreret position.Hereby one can use a housing without a ripper, which facilitates the manufacture of the housing and allows a faster and easier introduction of the structural unit consisting of contact blades and melting conductors. Below, the slipping of a contact knife into the housing is prevented by the insertion of at least one pin in the recesses on the housing surfaces, on which the second end plate at the base of the second contact knife in the housing is already in a centered position.

Til arretering af kontaktknivene kendes allerede stifter (DE-frem-læggelsesskrift 1 001 386). Boringer i kontaktknivene rummer her stifterne, som kun kan forhindre, at kontaktknivene kan trækkes ud af hu-20 set. De beskytter ikke mod indtrykning.Pins are already known for the arresting of the contact blades (DE-publication specification 1 001 386). Bores in the contact blades here contain the pins, which can only prevent the contact blades from being pulled out of the housing. They do not protect against impression.

I modsætning hertil forhindrer stifterne ved lavspændings-højef-fektsikringsindsatsen ifølge opfindelsen, at kontaktkniven kan trykkes tilbage ind i huset.In contrast, the pins of the low voltage high power protection insert of the invention prevent the contact knife from being pushed back into the housing.

Det er gunstigt at udforme en tap på hver endeplade på den side, 25 som vender bort fra kontaktkniven. Denne tap har i forhold til kontaktkniven hensigtsmæssigt et lille profil, for at mindske varmebortlednin-gen ved påsvejsning af smeltelederen med svejsepunkter. Den tjener ikke til arretering af kontaktkniven, som det derimod er tilfældet ved den indledningsvis nævnte, kendte sikring (DE-patentskrift 1 638 141) ved 30 hjælp af den knopformede bund.It is advantageous to design a pin on each end plate of the side 25 facing away from the contact knife. Conveniently, this pin has a small profile relative to the contact knife to reduce heat dissipation by welding the melting conductor with welding points. It does not serve to arrest the contact knife, as is the case with the prior art known fuse (DE Patent Specification 1 638 141) by means of the knob-shaped base.

Kontaktkniv, endeplade og tap kan udformes i ét stykke, hvorved overgangsmodstanden for lavspændings-højeffektsikringen formindskes.Contact knife, end plate and pin can be formed in one piece, thereby reducing the transition resistance of the low voltage high power fuse.

For at kunne anbringe et større antal smelteledere, kan endepladerne have udsparinger, som forstørrer disses overflade.In order to be able to place a greater number of melting conductors, the end plates may have recesses which enlarge their surface.

og kan derfor fremstilles af formstof. Der findes da ingen spændingsførende gribelasker, således at en betjeningsperson er beskyttet.and can therefore be made of plastic. There are then no live gripper joints, so that an operator is protected.

Lavspændings-højeffektsikringsindsatsen ifølge opfindelsen fremstilles på enkelt måde i det væsentlige af et færdig sikringshus af ke-5 ramik, af afslutningsplader og af en præfabrikeret byggeenhed kontakt-kniv-smelteleder. Enheden, som består af kontaktknive, endeplader og smelteledere, støttes af støttepunktflader ved randene på sikringshusets endeflader, og arreteres af de påskruede afslutningsplader. Medens endefladen af huset ved den tidligere omtalte kendte smeltesikring (DE-10 patentskrift 1 638 141) skal indføres i en not i kontaktkniven, lejres kontaktkniven ved sikringsindsatsen ifølge opfindelsen med endepladen på endesiden af huset. Det forenkler produktionen og resulterer i et fladere og sikrere støttepunkt.The low-voltage high-power fuse insert of the invention is manufactured in a simple manner substantially from a finished ceramic fuse housing, from end plates and from a prefabricated building unit contact-knife fusible conductor. The unit, which consists of contact blades, end plates and melt conductors, is supported by support point faces at the edges of the fuse housing end faces and is arranged by the screwed-off end plates. While the end surface of the housing is to be inserted into a groove in the contact knife by the previously mentioned known melt fuse (DE-10 patent 1 638 141), the contact knife of the invention according to the invention is stored with the end plate on the end side of the housing. It simplifies production and results in a flatter and safer support point.

Opfindelsen forklares i det følgende nærmere ved hjælp af på teg-15 ningen groft skematisk gengivne udførelseseksempler. På tegningen viser: fig. 1 en eksplosionsgengivelse af en sikringsindsats ifølge opfindelsen med to endeplader. Her er en af endefladerne så stor, at den i en centreret position ligger på en 20 ringformet støttepunktflade i huset.The invention will now be explained in more detail by way of example, in the drawing, roughly schematically illustrated embodiments. In the drawing: FIG. 1 is an exploded view of a fuse insert according to the invention with two end plates. Here, one of the end faces is so large that it is in a centered position on an annular support point face in the housing.

Fig. 2 en yderligere udformning af sikringsindsatsen. Her forhindres en afglidning af kontaktkniven i huset foruden ved hjælp af dettes støttepunktsflader også ved hjælp af stifter, som ligger i husets endeflader mellem endepla-25 derne og huset.FIG. 2 shows a further design of the hedging effort. Here, in addition to its support point surfaces, a slip of the contact knife in the housing is also prevented by means of pins which lie in the end faces of the housing between the end plates and the housing.

Det rørformede hus 1 ifølge fig. 1 er fremstillet af isolationsmateriale og omslutter en aksialt indført smelteleder 2, som ved hver af sine ender har en kontaktkniv 31, 32.The tubular housing 1 of FIG. 1 is made of insulating material and encloses an axially inserted melting conductor 2 which has a contact knife 31, 32 at each end thereof.

30 Kontaktkniven 31, 32, som befinder sig udenfor huset 1, har ved sin basis endeplader 16, 14. Endepladen 16 ligger efter radial forskydning af kontaktkniven på randen af huset 1.The contact knife 31, 32 located outside the housing 1 has at its base end plates 16, 14. The end plate 16 lies after radial displacement of the contact knife on the edge of the housing 1.

En ringformet støttepunktflade på randen af gennemføringsåbningerne i endefladerne 6 i huset 1 danner en hvileflade for det første 35 støttepunkt 73 på kontaktkniven 32. Den nederste, første endeflade 16 - 4 -An annular support point surface on the rim of the through-openings in the end faces 6 of the housing 1 forms a resting surface for the first 35 support point 73 on the contact knife 32.

har formen 71. Denne er i det væsentlige oval med notformede udsparinger 20. De griber formtilpasset ind i en modsvarende udformning 81 i huset 1, som er en yderligere udformet oval med en ribbe 21.has the shape 71. This is substantially oval with groove-shaped recesses 20. They engage the shape-fit into a corresponding configuration 81 in the housing 1, which is a further shaped oval with a rib 21.

På grund af de notformede udsparinger 20 kan den nederste, første 5 endeflade 16 ved indbygningen i huset 1 føres forbi ribben 21. Efter forskydningen af kontaktkniven 31 støtter endefladen 16 sig på ribben 21 og en modsvarende udformning et andet fladt støttepunkt.Due to the groove-shaped recesses 20, the lower first 5 end surface 16 can be passed by the housing 1 in the housing 1. After the displacement of the contact knife 31, the end surface 16 rests on the rib 21 and a similar design another flat support point.

Afslutningspladerne 9 og 10, som er skruet fast på endefladen 6 i huset 1, og som presser endepladerne 14 og 16 mod støttepunktfladen 5 10 ved randen af huset 1, arreterer kontaktknivene 31, 32. Afslutningspladerne 9 og 10 har åbninger til kontaktknivene 31, 32 og en hjælpe-smeltetråd 11. De behøver altså ikke at være spændingsførende og kan derfor består af formstof. Det samme gælder for gribelaskerne 12, som er dele af de ydre tilslutningsplader 10. Tilslutningspladerne 9 kan 15 også på gængs måde udformes som tætninger af asbest eller asbestlig nende materiale.The termination plates 9 and 10, which are screwed onto the end face 6 of the housing 1 and which press the end plates 14 and 16 against the supporting point face 5 10 at the edge of the housing 1, arrest the contact blades 31, 32. The termination plates 9 and 10 have openings for the contact blades 31, 32 and an auxiliary melting wire 11. Thus, they do not need to be live conducting and can therefore consist of plastic. The same is true of the gripper lugs 12, which are parts of the outer connection plates 10. The connection plates 9 can also be formed in the usual way as seals of asbestos or asbestos-resistant material.

Mellem endepladerne 14 og 16 og smeltelederen 2 er der udformet tappe 13 Disse har hensigtsmæssigt en mindre profil end kontaktkniven 31 og 32, hvorhos en eller flere smelteledere 2 let kan svejses på 20 tappen 13. Kontaktkniven 31 og 32, endepladen 14 og 16 og tappen 13 lader sig fremstille i ét stykke ved mekanisk formning.Pin 13 is formed between the end plates 14 and 16 and the melt conductor 2. These are suitably of a smaller profile than the contact knife 31 and 32, where one or more melt conductors 2 can be easily welded to the pin 13. The contact knife 31 and 32, the end plate 14 and 16 and the pin 13 can be made in one piece by mechanical molding.

Den anden endeplade 14 har en i det væsentlige oval udformning 73 uden notagtig udsparing 20. Den er udformet så stor, at den i en centreret position kun ligger på den ringformede hvileflade 5.The second end plate 14 has a substantially oval configuration 73 without noticeable recess 20. It is so large that in a centered position it rests only on the annular resting surface 5.

25 Enheden bestående af kontaktknivene 31, 32, endepladerne 16, 14 og smeltelederen 2 indbygget i huset ovenfra. Når den anden endeplade 14 ligger på hvilefladen 5, sammentrykkes smeltelederen 2 så meget, at den første endeplade 16 forskydes radialt, således at den ligger på rippen 21.The unit consisting of the contact blades 31, 32, the end plates 16, 14 and the melt conductor 2 built into the housing from above. When the second end plate 14 lies on the resting surface 5, the melt conductor 2 is compressed so much that the first end plate 16 is radially displaced so that it lies on the ridge 21.

30 Den anden endeplade 17 ifølge fig. 2 har en i det væsentlige oval udformning 74 og ligger udvendigt på den ringformede hvileflade 5 på stifter 18. Disse lægges først ind efter indbygnigen af enheden bestående af kontaktkniven 31 og 32, endeplader 17, 22 og smelteleder 2 i udsparinger i endesiden 6 på huset 1, således at de rækker hen over 35 husåbningen.The second end plate 17 of FIG. 2 has a substantially oval configuration 74 and exteriorly of the annular resting surface 5 of pins 18.
