Description

450 982 Uppfinningen kommer nu att beskrivas mer detaljerat med hänvisning till' bifogade ritning. ' På ritningen är fig. l en perspektivbild av en utföringsform av konden- satorn enligt uppfinningen, fig. 2 en sidosektion av utföringsformen enligt fig. 1 och fig. 3 en sidosektion av en annan utföringsform av kondensatorn enligt uppfinningen. 450 982 The invention will now be described in more detail with reference to the accompanying drawing. In the drawing, Fig. 1 is a perspective view of an embodiment of the capacitor according to the invention, Fig. 2 a side section of the embodiment according to Fig. 1 and Fig. 3 a side section of another embodiment of the capacitor according to the invention.

I ritningarna har samma hänvisningssiffror givits motsvarande konstruk- tionskomponenter.In the drawings, the same reference numerals have been given to the corresponding design components.

Som framgår av fig. 1 och 2 innefattar kondensatorn ett par rännformiga metallkontaktorgan 1 och 2 med L-formig tvärsektion- Kontaktorganen 1 och 2 är anordnade, såsom visas, för att ha sina vertikala partier vända mot varandra och sina horisontella partier i ett gemensamt plan. En anodledare 4 hos ett konden- satorelement 3 är svetsat vid kontaktorganet 1 och ett katodskikt 5 av elementet 3 är förbundet med kontaktorganet 2 med lod eller elektriskt ledande bindemedel 6. Kondensatorelementet 3 är.inbäddat i isolerande syntetiskt harts 8, som fyller ett utrymme mellan de båda kontaktorganen l och 2, och en tunn platta av syntetiskt harts 7 är fäst vid den övre ytan av hartset 8.As shown in Figs. 1 and 2, the capacitor comprises a pair of gutter-shaped metal contact members 1 and 2 with L-shaped cross-section. The contact members 1 and 2 are arranged, as shown, to have their vertical portions facing each other and their horizontal portions in a common plane. . An anode conductor 4 of a capacitor element 3 is welded to the contact member 1 and a cathode layer 5 of the element 3 is connected to the contact member 2 by solder or electrically conductive adhesive 6. The capacitor element 3 is embedded in insulating synthetic resin 8, which fills a space between the two contact means 1 and 2, and a thin plate of synthetic resin 7 is attached to the upper surface of the resin 8.

Kontaktorganen l och 2 kan vara framställda av lödbar metallplåt, såsom av koppar, nickel eller nickelsilver eller en lämplig metall, som är belagd med lödbart material, såsom lod, tenn eller guld. Kondensatorelementet 3 kan beredas på konventionellt sätt- Exempelvis kan på lämpligt sätt pulveriserad ventilme- tall, lämpligen tantal, pressformas och sintras till bildande av en anodkropp och ett oxidskikt, ett halvledarskikt och ett katodskikt utfälls i följd i nämnda ordning på anodkroppen. "Ventilmetallen" är en sådan metall, såsom_tan- tal, aluminium, zirkon, titan, niob eller liknande, vilken uppvisar "ventil- verkan", dvs ensriktad elektrisk ledningsförmåga mellan metallen och dess oxidbeläggning. Hartset 8 kan väljas bland elektriskt isolerande lufthärdande, strålningshärdande eller värmehärdande, vidhäftande hartser, såsom epoxiharts.The contact means 1 and 2 may be made of solderable sheet metal, such as of copper, nickel or nickel silver or a suitable metal coated with solderable material, such as solder, tin or gold. The capacitor element 3 can be prepared in a conventional manner. The "valve metal" is a metal such as tantalum, aluminum, zirconium, titanium, niobium or the like which exhibits "valve action", i.e., unidirectional electrical conductivity between the metal and its oxide coating. The resin 8 can be selected from electrically insulating air-curing, radiation-curing or heat-curing adhesive resins, such as epoxy resin.

Hartsplattan 7 kan med fördel vara av polyimidharts, polyetenfluoridharts eller glasfylld epoxiharts. Hartsplattan 7 är med fördel fäst vid hartsytan med bindemedelskraft av hartset 8 själv, innan det härdas, även om det kan vidhäftas med separata bindemedel efter härdning av hartset 8. Plattans 7 tjocklek kan vara tillräckligt liten, såsom 0,2 mm exempelvis, så länge som den möjliga vâgformen på ytan av hartset 8 icke uppträder på ytan av plattan 7.The resin plate 7 can advantageously be made of polyimide resin, polyethylene fluoride resin or glass-filled epoxy resin. The resin plate 7 is advantageously attached to the resin surface by adhesive force of the resin 8 itself, before it is cured, although it may be adhered with separate adhesives after curing of the resin 8. The thickness of the plate 7 may be sufficiently small, such as 0.2 mm for example, as long as as the possible waveform on the surface of the resin 8 does not appear on the surface of the plate 7.

I fig. 3 täcker hartsplattan 7 endast en del av hartsets 8 yta. flattans 7 form kan vara icke blott rektangulär utan även cirkulär eller ha annan lämplig form. ßIn Fig. 3, the resin plate 7 covers only a part of the surface of the resin 8. the shape of the surface 7 can be not only rectangular but also circular or have another suitable shape. ß
