Description
508 552 10 15 20 25 30 35 2 Ytterligare särdrag hos och fördelar med uppfinningen kommer att framgå av den detaljerade beskrivningen som följer och som ges under hänvisning till de àtföljande ritningarna, vilka tillhandhàlls enbart i form av icke be- gränsande exempel och pà vilka: Fig 1 är en sprängskiss över en elektronisk enhet i enlighet med uppfinningen; Fig 2 är en planvy över en del av den elektroniska enheten som visas i fig 1; och Pig 3 är en sektion, som är tagen längs linjen III-III i fig 2. 508 552 10 15 20 25 30 35 2 Additional features and advantages of the invention will be apparent from the detailed description which follows and given with reference to the following the drawings, which are provided solely in the form of boundary examples and on which: Fig. 1 is an exploded view of an electronic device in in accordance with the invention; Fig. 2 is a plan view of a part of the electronic the unit shown in Fig. 1; and Pig 3 is a section taken along the line III-III in Fig. 2.
Såsom visas i fig l innefattar den elektriska enheten enligt uppfinningen en plan bärare l av elektriskt isole- exempelvis en keram, som på sin ena yta som innefattar ledande banor 2, rande material, bär en elektronisk krets, passiva komponenter 2a och ett flertal elektroniska fast- fasenheter 3, i synnerhet integrerade kretsar. De integre- rade kretsarna 3 är anslutna till de ledande banorna 2 med tunna, svetsade, ledande trådar 4.As shown in Fig. 1, the electrical unit includes according to the invention a flat carrier 1 of electrically insulated for example, a ceramic, which on its one surface comprising conductive paths 2, material, carries an electronic circuit, passive components 2a and a plurality of electronic fixed phase units 3, in particular integrated circuits. The integrated The circuits 3 are connected to the conductive paths 2 by thin, welded, conductive wires 4.
Bärarens 1 andra yta är limmad tillïen metallplatta 5, som har till uppgift att avleda värme. Plattan 5 kan exempelvis bestå av aluminium.The second surface of the carrier 1 is glued to a metal plate 5, which has the task of dissipating heat. Plate 5 can for example, consist of aluminum.
Plattan 5 är limmad, exempelvis medelst en epoxy- harts, till kanten hos en isolerande kapsel, som betecknas allmänt med 6. I den visade utföringsformen har denna kap- sel ett väsenligen ringformigt element 7 och ett lock 8.The plate 5 is glued, for example by means of an epoxy resin, to the edge of an insulating capsule, designated generally with 6. In the embodiment shown, this cap- a substantially annular element 7 and a lid 8.
Det ringformiga elementet 7 är lämpligen utformat i ett plastmaterial, exempelvis polybutylentereftalat, och har ett spàr 9 i sin övre yta, som är i ingrepp med en pe- riferiell kant hos locket 8 med lim anbringat emellan.The annular element 7 is suitably formed in a plastic material, for example polybutylene terephthalate, and has a groove 9 in its upper surface, which engages a pe- referral edge of the lid 8 with glue applied in between.
Detta lock 8 utgörs också lämpligen av ett plastmaterial, exempelvis polyamid.This lid 8 is also suitably made of a plastic material, for example polyamide.
De isolerande elementen 7 och 8 avgränsar tillsammans en kammare, som visas vid 10 i fig 3, i vilken locket 8 utgör tak och det ringformiga elementet 7 utgör sidoväg- gar. 10 15 20 25 30 35 508 552 3 Plattan 5 med den tillhörande bäraren 1 är limmad till det ringformiga elementet 7 vid sin kant som är mot- satt locket 8, så att de kretsar som bärs av bäraren vet- ter in i kammaren 10.The insulating elements 7 and 8 delimit together a chamber, shown at 10 in Fig. 3, in which the lid 8 forms a roof and the annular element 7 forms a side road gar. 10 15 20 25 30 35 508 552 3 The plate 5 with the associated carrier 1 is glued to the annular element 7 at its edge which is set the cover 8 so that the circuits carried by the carrier enters the chamber 10.
Inre skiljeväggar ll skjuter ut fràn det ringformiga elementets 7 sidoväggar och bildar ett slags nät, som ut- sträcker sig i ett plan som är väsentligen vinkelrätt mot bärarens 1 plan. Dessa skiljeväggar omger zoner i kammaren 10 som täcker de elektroniska enheterna 3.Internal partitions ll protrude from the annular the side walls of the element 7 and form a kind of net, which extends in a plane that is substantially perpendicular to the carrier's 1 plane. These partitions surround zones in the chamber 10 covering the electronic devices 3.
Kammaren 10 är delvis fylld med en isolerande gel (som visas vid 12 i fig 3), som täcker de elektroniska kretsarna som bärs av bäraren 1.The chamber 10 is partially filled with an insulating gel (shown at 12 in Fig. 3), which covers the electronic ones the circuits carried by the carrier 1.
Skiljeväggarna ll, som omger, sàsom redan har nämnts, zonerna i kammaren 10 som täcker de elektroniska enheterna 3, begränsar den isolerande gelens 12 rörelse när enheten är i bruk. Således elimineras risken för att de elektro- niska komponenternas 3 tunna, lödda trådar skall slitas sönder genom plötsliga rörelser hos denna gel i kammaren 10. l Det ringformiga elementet 7 har ett i ett stycke med detta utformat utskott 13 pà sin ytteryta, vilket utskott bildar en elektrisk anslutning via vilken ledande anslut- ningsorgan 14 sträcker sig, vilka är anslutna till den elektroniska kretsen som uppbärs av bäraren 1.The partitions ll, which surround, as already mentioned, the zones in the chamber 10 covering the electronic devices 3, restricts the movement of the insulating gel 12 when the unit is in use. This eliminates the risk of the electrodes The 3 thin, brazed wires of the mechanical components must be worn broken by sudden movements of this gel in the chamber 10. l The annular element 7 has one in one piece with this formed committee 13 on its outer surface, which committee forms an electrical connection via which conductive extending means 14, which are connected to it electronic circuit supported by the carrier 1.
Dessa ledande element kan införlivas i det ringformi- ga elementet 7 under gjutningen av detta. Detta ringformi- ga elements skiljeväggar ll tillverkas lämpligen i ett stycke med elementet i gjutfasen.These conductive elements can be incorporated into the annular gave the element 7 during the casting thereof. This ring-shaped partitions of the element ll are suitably manufactured in one piece with the element in the casting phase.
Naturligtvis kan formarna hos utförandet och struktu- rella detaljer varieras vitt med avseende pà de beskrivna och visade, som endast utgör icke begränsade exempel, så länge principen för uppfinningen förblir densamma, varvid uppfinningen inbegrier samtliga utföringsformer som uppnår samma funktion i kraft av samma uppfinningskoncept.Of course, the shapes of the embodiment and structures real details vary widely with respect to those described and showed, which are only unlimited examples, so as long as the principle of the invention remains the same, wherein the invention includes all embodiments that achieve the same function by virtue of the same concept of invention.
