Opfindelsen angår et indkapslingshus, hvori er anbragt en elektrisk komponent, hvilket indkapslingshus er tillukket med et låg, der ved en snapforbindelse er indtrykket i en rille indvendigt i indkapslingshuset, og gennem hvilket låg komponentens elektriske tilledninger føres ud af indkapslingshuset.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an enclosure housing in which an electrical component is provided, which enclosure housing is closed by a lid, which is snap-fastened internally within the enclosure housing and through which the electrical components of the component conductor are discharged from the enclosure housing.

Der kendes allerede indkaplingshuse for elektriske komponenter, hvori et låg eller dæksel ved en snapforbindelse indtrykkes i en rille i indkapslingshuset, jvf. USA-patentskrift nr. 3.197,547 og tysk offentliggørelsesskrift nr. 1.564.727.There are already known enclosures for electrical components in which a lid or cover is snap-pressed into a groove in the enclosure housing, cf. U.S. Patent No. 3,197,547 and German Publication No. 1,564,727.

Brugen af sådanne indkapslingshuse, omfattende låg med snap-forbindelse, og bestemt til at indeholde elektriske komponenter, letter i væsentlig grad samlingsarbejdet, eftersom ingen specialanordning er påkrævet til anbringelse af låget, og befæstelsen etableres ved blot kortvarigt at indtrykke låget i indkapslingshusets rille. I sammenligning hermed er den hidtil benyttede tillodning eller tilbørtling af lågene væsentlig dyrere.The use of such enclosure housings, comprising snap-on lids, and intended to contain electrical components, greatly facilitates assembly work, as no special device is required to place the lid, and the fastening is established by simply briefly pressing the lid into the housing of the enclosure. By comparison, the hitherto used soldering or bending of the lids is considerably more expensive.

Det har dog vist sig, at der i nogle tilfælde ikke opnås en tilfredsstillende befæstelse af låget ved indsnapningsmeto-den, når låget ikke med hele sin periferi slutter fuldstændigt i husets rille. Dette kan f.eks. være tilfældet, når låget ikke er helt plant, men af en eller anden grund er deformeret. I tilfælde af lågets ufuldstændig indsnapning i husets rille er der fare for at låget bliver løst, og således ikke længere beskytter den indkapslede komponent.However, it has been found that in some cases a satisfactory fastening of the lid is not achieved by the snap-in method, when the lid does not end completely with its entire periphery in the groove of the housing. This can be done, for example. be the case when the lid is not completely level but for some reason is deformed. In the event of the lid's incomplete enclosure in the housing groove, there is a danger of the lid being loosened and thus no longer protects the encapsulated component.

Ydermere er det ved de konventionelle hustyper stadigvæk nødvendigt at lodde eller nitte de elektriske forbindelses-tråde til egnede terminaler på låget.Furthermore, with the conventional housing types, it is still necessary to solder or rivet the electrical connecting wires to suitable terminals on the lid.

Det er formålet med opfindelsen yderligere at forbedre indkapslingshuse med indsnapnings-lågtype til elektriske komponenter, således at samlingsarbejdet simplificeres og ac-celeres.SUMMARY OF THE INVENTION It is an object of the invention to further improve enclosure housing with enclosure cover type for electrical components so as to simplify and accelerate assembly work.

Dette opnås ifølge opfindelsen ued, at låget på begge sider har individuelle indsnapningsdele jævnt fordelt langs lågets periferi, og hvor de på undersiden anbragte indsnapningsdele indgriber i nævnte rille i huset, medens de på oversiden anbragte indsnapningsdele fastholder et tilslutningsstykke til lågets overside.This is achieved according to the invention without the lid on either side having individual snap portions evenly distributed along the circumference of the lid and where the underside snap-in parts engage in said groove in the housing, while the upper snap-in snap-in portions retain a connection piece to the top of the lid.

Det har vist sig, at der, ved anbringelse af individuelle separate indsnapningsdele jævnt fordelt langs lågets periferi, altid kan opnås en upåklagelig indsnapning af låget i huset. Ved symmetrisk fordeling af indsnapningsdelene fastholdes låget ensartet og pålideligt langs hele periferien. Anbringelsen af låget simplificeres også derved, at forbindelsestrådene ikke behøver at forbindes til terminaldele anbragt på låget, men kun behøver at føres gennem åbninger i låget, hvorefter låget trykkes ind i huset.It has been found that, by placing individual separate snap-parts evenly distributed along the periphery of the lid, an impeccable snap-in of the lid can always be achieved. By symmetrically distributing the snap-in parts, the lid is maintained uniformly and reliably along the entire periphery. The placement of the lid is also simplified in that the connecting wires do not need to be connected to terminal parts located on the lid, but only need to be passed through openings in the lid, after which the lid is pressed into the housing.

Til elektrisk forbindelse af komponenten bruges et særskilt tilslutningsstykke, hvori forbindelses- eller tilledninger fastklemmes i deres stilling fortrinsvis ved hjælp af spæn-destykker eller clips, idet dette tilslutningsstykke monteres på lågets topside ved hjælp af indsnapningsdele.For electrical connection of the component, a separate connection piece is used in which connection or leads are clamped in their position preferably by means of clamps or clips, this connection piece being mounted on the top side of the lid by means of snap-in parts.

Sådanne spændestykker er i særdeleshed bestemt til flade tilslutningstråde. For også at kunne tilføre runde tråde pålideligt i spændestykkerne er der på lågets overside -ifølge en udførelsesform for opfindelsen - anbragt ledeorganer, som fører den indstukne trådende frem til kort før spændestykket.Such clamps are in particular intended for flat connection wires. In order to be able to reliably supply round threads to the clamping pieces, there is also provided, on the upper side of the lid, an embodiment of the invention - guiding means which carry the threaded thread forward shortly before the clamping piece.

Opfindelsen samt fordelagtige yderligere udformninger af denne vil nu blive nærmere gennemgået under henvisning til tegningen, på hvilken: fig. 1 og 2 viser indkapslingshusets enkelte dele i snit-afbildning, d.v.s. på fig. la, lb og lc inden samlingsarbejdet, og på fig. 2 efter samlingsarbejdet.The invention and advantageous further embodiments thereof will now be further elucidated with reference to the drawing, in which: FIG. 1 and 2 show the individual parts of the enclosure housing in sectional view, i.e. in FIG. 1a, 1b and 1c before the assembly work, and in fig. 2 after the assembly work.

Fig. 3a wiser låget i snitafbildning, medens fig. 3b viser det set fra oven.FIG. 3a shows the lid in sectional view, while FIG. 3b shows it from above.

Fig. 4a viser forbindelsesstykket i snitafbildning, og fig. 4b viser dette set fra oven.FIG. 4a shows the connector in sectional view; and FIG. 4b shows this from above.

På figurerne la - le vises i snitafbildning de enkelte dele af indkapslingshuset ifølge opfindelsen. Huset 1, der såvel kan bestå af metal som af kunststof, har på sin øvre del en rille 12, der tjener til lågets indsnapning. Ovenfor rillen 12 er der til låget placeret en vulst 11 så langt fra husets overkant, at låget efter indsnapningen kan flugte med denne overkant. Indenfor huset 1 er komponenten 4 placeret, f.eks. en elektrisk kondensator med forbindelses- eller tilledninger 41. Fortrinsvis er der ved husets bund anbragt en indsnapnings-fod 13, bestemt til at fasttrykke huset i et hul i en plade ved simpel indsnapning. Fortrinsvis har indsnapningsfoden 13 rektangulært tværsnit, så at den kan indsættes udrejeligt i et tilsvarende formet hul i monteringspladen.The figures 1a show in sectional view the individual parts of the enclosure housing according to the invention. The housing 1, which can consist of metal as well as plastic, has on its upper part a groove 12 which serves for the cover of the lid. Above the groove 12, a bead 11 is placed so far from the upper edge of the housing that the lid can flush with this upper edge after the snap. Within the housing 1, the component 4 is located, e.g. an electrical capacitor with connecting or conduits 41. Preferably, at the bottom of the housing, a snap-in foot 13 is provided for securing the housing to a hole in a plate by simple snap-in. Preferably, the snap-in foot 13 has a rectangular cross-section so that it can be removably inserted into a correspondingly shaped hole in the mounting plate.

Det i fig. Ib viste låg 2 til huset består af en pladeformet del, hvorpå indsnapningsdele 21 er udformet på undersiden og indsnapningsdele 22 på oversiden. Indsnapningsdelene 21 har fortrinsvis segmentformet karakter, medens indsnapningsdelene 22 er fingerformede. Oversiden af låget 2 er fortrinsvis forsynet med en krave 23, der tjener til centrering af et derpå anbragt tilslutningsstykke 3. I låget findes huller 24 til gennemføring af den elektriske komponents tilslutnings-tråde 41. For at føre disse forbindelsestråde frem til indsætning i forbindelsesklemmerne i tilslutningsstykket 3 er der på dækslets overside anbragt ledeorganer 25.The FIG. 1b, the housing 2 shown in Fig. 1b consists of a plate-shaped part on which snap-in portions 21 are formed on the underside and snap-in parts 22 on the upper side. The snap-in portions 21 are preferably segment-shaped, while the snap-in parts 22 are finger-shaped. The upper surface of the lid 2 is preferably provided with a collar 23 which serves to center a connecting piece 3. There are holes 24 for inserting the electrical components connection wires 41. In order to pass these connecting wires for insertion into the connection terminals in the connecting member 3 is provided with guide members 25 on the upper side of the cover.

Det i snitafbildning på fig. la viste tilslutningsstykke er af kapselformet karakter og er indvendig forsynet med klemme forbindelser til at fiksere den elektriske komponents tilledninger. Dette klemmearrangement er fortrinsvis således udformet, at der på oversiden kan indstikkes homogen tråd 144230 4 eller litzetråd.The sectional view of FIG. 1a, the connector shown in capsule is of a capsule-shaped nature and is internally provided with clamping connections for fixing the electrical component wires. This clamping arrangement is preferably designed such that homogeneous thread or litz thread can be inserted on the upper side.

I fig. 2 er huset vist i sammenbygget tilstand, samtidig med at det heri fremgår, hv/ordan huset kan monteres på en plade, hvori indsnapningsfoden 13 er indtrykket gennem et hul. Af fig. 2 fremgår det også at låget 2 hviler mod vul-sten 11, idet indsnapningsdelene 21 indgriber i husets rille 12. Samtidig fastholder indsnapningsdelene 22 tilslutningsstykket 3 tæt til oversiden af låget 2. Den elektriske komponents forbindelsestråde 41 er ført gennem lågets huller og fastspændt i klemmerne 31 inden i tilslutningsstykket.In FIG. 2, the housing is shown in a assembled state, while at the same time it appears that the housing can be mounted on a plate in which the snap base 13 is pressed through a hole. In FIG. 2, it is also seen that the lid 2 rests against the bead 11, with the snap-in parts 21 engaging in the groove 12. At the same time, the snap-in parts 22 hold the connection piece 3 close to the upper side of the lid 2. The connecting wire 41 of the electrical component is passed through the holes of the lid and clamped in the clamps. 31 inside the connector.

Samlingsarbejdet er meget simpelt. Den elektriske komponent 4 indsættes i huset 1. Derpå føres forbindelsestrådene 41 gennem hullerne 24 i låget 2, hvilket lettes deraf, at disse huller på undersiden har en konisk udvidelse. Ledeorganerne 25 simplificerer indstikningen af trådene 41 i klemmerne på tilslutningsstykket 3. For at forhindre at trådene 41 efter gennemstikningen glider tilbage gennem dækslets huller, kan de udragende trådender fladtrykkes. Derefter indtrykkes låget i huset, hvorved indsnapningsdelene 21 passerer vul-sten 11 og griber ind i rillen 12 i huset 1, hvorved låget kommer til at hvile mod vulsten 11. Nu fastklemmes de af ledeorganerne 25 udragende ender af tilslutningstrådene 41 indført nedefra i tilslutningsstykket 3, til dettes klemmer 31. Samtidig indsnappes tilslutningsstykket 3 til låget 2, hvorved indsnapningsdelene 22 fastholder tilslutningsstykket 3 i sin stilling.The assembly work is very simple. The electrical component 4 is inserted into the housing 1. Then the connecting wires 41 are passed through the holes 24 in the lid 2, which is facilitated by the fact that these holes on the underside have a tapered extension. The guide members 25 simplify the insertion of the wires 41 into the terminals of the connection piece 3. To prevent the wires 41 from sliding back through the holes of the cover after the piercing, the protruding thread ends can be flattened. Then, the lid is pressed into the housing, whereby the snap-in parts 21 pass the bead 11 and engage the groove 12 in the housing 1, whereby the lid will rest against the bead 11. Now the ends protruding by the guide members 25 are clamped by the connecting wires 41 introduced from below into the connection piece 3 , to its terminals 31. At the same time, the connecting piece 3 is snapped to the cover 2, whereby the snap-in parts 22 hold the connecting piece 3 in its position.

På fig. 3 er låget vist, nemlig i snitafbildning på fig. 3a og set fra oven på fig. 3b. Det ses af disse figurer, at indsnapningsdelene 21 har segmentformet karakter og er jævnt fordelt langs omkredsen af låget 2, medens indsnapningsdelene 22 har fingerformet karakter. Endvidere ses den ringformede krave 23, der tjener til centrering af det kapselformede tilslutningsstykke 3 ved dets anbringelse på låget 2.In FIG. 3, the lid is shown, namely in sectional view of FIG. 3a and seen from above in FIG. 3b. It can be seen from these figures that the snap-in portions 21 are segmental in character and are evenly distributed along the circumference of the lid 2, while the snap-in parts 22 are finger-shaped. Also seen is the annular collar 23 which serves to center the capsule-shaped connection piece 3 upon its placement on the lid 2.
