Die Erfindung bezieht sich auf ein elektronisches Steuergerät mit den Merkmalen, die im Oberbegriff des Patentanspruchs 1 angegeben sind, sowie auf ein Verfah­ ren zur Herstellung eines derartigen Steuergeräts.The invention relates to an electronic control unit with the features which are specified in the preamble of claim 1, and to a procedure ren for the production of such a control device.

Ein derartiges Steuergerät und ein Verfahren zu seiner Herstellung ist aus der DE 44 04 986 A1 bekannt. Die Leiterbahnstruktur wird dabei auf einem Träger be­ festigt. Anschließend werden die elektronischen Bauelemente mit der Leiterbahn­ struktur kontaktiert. Am Einsatzort, hier einem mit dem Steuergerät gesteuerten Elektromotor wird der Träger mit einer Abdeckung versehen, so daß die Leiter­ bahnstruktur und die Bauelemente von einem Gehäuse ummant sind.Such a control device and a method for its production is from the DE 44 04 986 A1 known. The conductor track structure is on a carrier consolidates. Then the electronic components with the conductor track structure contacted. On site, here one controlled by the control unit Electric motor, the carrier is provided with a cover so that the conductor track structure and the components are encased in a housing.

Die Herstellung des bekannten Steuergeräts ist aufwendig. Zudem besitzt das Steuergerät eine geringe mechanische Stabilität, da beispielsweise das Gehäuse lediglich Schutz vor Feuchtigkeit oder Verschmutzung bietet, nicht jedoch die me­ chanische Stabilität des Steuergeräts erhöht. Diese wird im wesentlichen lediglich durch die Festigkeit des Trägers bestimmt.The production of the known control unit is complex. It also has Control unit has low mechanical stability because, for example, the housing only provides protection against moisture or pollution, but not me mechanical stability of the control unit increased. This is essentially just determined by the strength of the wearer.

Der Erfindung liegt die Aufgabe zugrunde, ein elektronisches Steuergerät der ein­ gangs genannten Art zu schaffen, das eine hohe mechanische Stabilität besitzt und das darüber hinaus auf besonders einfache Weise herzustellen ist.The invention has for its object an electronic control unit gangs mentioned to create that has a high mechanical stability and it is also easy to manufacture.

Die Erfindung löst diese Aufgabe für das Steuergerät hinsichtlich der mechani­ schen Stabilität durch die kennzeichnenden Merkmale des Patentanspruchs 1 und hinsichtlich des Herstellungsverfahrens durch die kennzeichnenden Merkmale des Patentanspruchs 3.The invention solves this problem for the control unit in terms of mechani stability by the characterizing features of claim 1 and  with regard to the manufacturing process through the characteristic features of the Claim 3.

Das Steuergerät besitzt nunmehr ein in Kunststoff-Spritztechnik hergestelltes Ge­ häuse, das zu einem kompakten und gegen mechanische sowie thermische und atmosphärische Einflüsse weitgehend unempfindlichen Aufbau führt. Die Herstel­ lung erfolgt mit Hilfe der von integrierten Schaltkreisen bekannten Spritztechnik, die einfach zu handhaben ist und die einen hohen Reifegrad besitzt. Abhängig vom verwendeten Kunststoff und/oder dem angewandten Herstellungsverfahren lassen sich die mechanischen und thermischen Eigenschaften des Steuergeräts den je­ weiligen Anforderungen optimal anpassen.The control unit now has a Ge manufactured in plastic injection molding technology housing that is compact and against mechanical as well as thermal and largely insensitive to atmospheric influences. The manufacturer tion takes place with the help of the spray technology known from integrated circuits, which is easy to use and has a high level of maturity. Depending on the used plastic and / or the manufacturing process used the mechanical and thermal properties of the control unit ever optimally adapt to certain requirements.

Vorteilhafte Ausgestaltungen des Steuergeräts sind Gegenstand des Patentan­ spruchs 2 und ermöglichen, die Einsatzmöglichkeiten des Steuergeräts zu vergrö­ ßern. Durch die Verwendung zusätzlicher Leiterbahn-Strukturabschnitte lassen sich empfindliche Bauelemente, die während der Herstellung des Gehäuses Scha­ den nehmen würden, auslagern und erst nachträglich am Steuergerät befestigen. Dadurch ergibt sich die Möglichkeit, die Kunststofftechnik noch mehr den geforder­ ten mechanischen Eigenschaften des Gehäuses anzupassen, da auf die Belast­ barkeit der ansonsten innerhalb des Gehäuses angeordneten elektrischen Bauteile dann keine Rücksicht mehr genommen zu werden braucht.Advantageous embodiments of the control device are the subject of the patent Proposition 2 and allow to increase the possible uses of the control unit eat. By using additional conductor track structural sections sensitive components that Scha would take it, outsource it and attach it to the control unit only afterwards. This results in the possibility that plastics technology meets the requirements even more adapt the mechanical properties of the housing to the load Availability of the electrical components otherwise arranged within the housing then no more consideration needs to be taken.

Im Rahmen des Herstellungsverfahrens lassen sich die Kontaktteile nachträglich den jeweiligen Anforderungen anpassen. Sie können als Steck-, als Löt- oder an­ dere Anschlüsse ausgebildet werden. Neben der Möglichkeit, diese Kontakte nachträglich auszubilden, besteht auch die Möglichkeit, diese Kontakte vor dem Umspritzen der Bauteile, beispielsweise bei der Herstellung des Stanzteils selbst bereits auszubilden.The contact parts can be retrofitted as part of the manufacturing process adapt to the respective requirements. You can use it as a plug-in, as a solder or on whose connections are formed. In addition to the possibility of these contacts training afterwards, there is also the possibility of these contacts before Injection molding of the components, for example in the manufacture of the stamped part itself already training.

Fig. 8 eine weitere Ausführungsvariante des Steuergeräts in Seitenansicht. Fig. 8 shows a further embodiment of the control unit in side view.

Das in Fig. 1 dargestellte elektronische Steuergerät besteht im wesentlichen aus einem Gehäuse 2, aus dem Steckkontakte 3, Anschlußkontakte 4 und 4′ (Fig. 2) sowie weitere Anschlußkontakte 5 hervorstehen. Es dient beispielsweise dazu, einen Schrittmotor zu steuern (Fig. 7).The electronic control unit shown in Fig. 1 consists essentially of a housing 2 , from the plug contacts 3 , connection contacts 4 and 4 '( Fig. 2) and further connection contacts 5 protrude. It is used, for example, to control a stepper motor ( Fig. 7).

Das Steuergerät 1 wird hergestellt aus einem Blechstanzteil 6, das aufgebaut ist aus einem Hilfsrahmen 7 und mit diesem verbundenen Kontaktteilen 3, 4 und 5 sowie den Kontakten 4 entsprechenden korrespondierenden Kontaktteilen 4′, Lei­ terbahnabschnitten 8 sowie einem zentralen Träger 9. Nach Herstellung des Blechstanzteils 6 werden elektronische Bauteile wie ein Chipkondensator 10 und ein Mikroprozessor 11 an den eingezeichneten Stellen fixiert und über Bonddrähte mit den zugehörigen Anschlüssen 3, 4, 4′ und 5 verbunden (Fig. 3).The control unit 1 is made of a stamped sheet metal part 6 , which is constructed from an auxiliary frame 7 and connected to this contact parts 3 , 4 and 5 and the contacts 4 corresponding corresponding contact parts 4 ', Lei terbahnabschnitte 8 and a central support. 9 After the stamped sheet metal part 6 has been produced , electronic components such as a chip capacitor 10 and a microprocessor 11 are fixed at the points shown and connected to the associated connections 3 , 4 , 4 'and 5 via bond wires ( FIG. 3).

Anschließend wird das Stanzteil mit Kunststoff umgeben und das Gehäuse 13 gebildet (Fig. 4). Dabei wird eine an sich bekannte Kunststoff-Spritztechnik ange­ wandt.The stamped part is then surrounded with plastic and the housing 13 is formed ( FIG. 4). A known plastic injection molding technique is used.

Anschließend wird der Hilfsrahmen 7 wie dargestellt entfernt. Die Anschlüsse 3, 4, 4′ und 5 bleiben stehen und können beispielsweise nachbehandelt werden. Sie können beispielsweise verlötet oder wie bei den Anschlüssen 4 und 4′ angedeutet an der eingezeichneten Stelle ausgestanzt und so mit Öffnungen versehen wer­ den. Subsequently, the subframe 7 is removed as shown. The connections 3 , 4 , 4 'and 5 remain and can be treated, for example. You can, for example, soldered or punched out as indicated in the connections 4 and 4 'at the location shown and thus provided with openings to who.

Das so gebildete Steuergerät ist mechanisch stabil. Die Bauteile sowie die zu den Anschlüssen führenden Bonddrähte sind gegen äußere Einflüsse thermischer, me­ chanischer und chemischer Art völlig geschützt.The control device thus formed is mechanically stable. The components as well as the Connections leading bond wires are thermal against external influences, me chanical and chemical type completely protected.

Beim Ausführungsbeispiel von Fig. 6 ist gezeigt, wie die beiden Anschlüsse 5 dazu verwendet werden, ein ausgelagertes Bauteil, beispielsweise einen Resonator 14 zu tragen. Dieser wird nach der Herstellung des Gehäuses 13 angeordnet. Hierbei können die Anschlüsse 5 nach oben gebogen werden (Fig. 1).The embodiment of FIG. 6 shows how the two connections 5 are used to support an outsourced component, for example a resonator 14 . This is arranged after the manufacture of the housing 13 . Here, the connections 5 can be bent upwards ( FIG. 1).

Das so gebildete Steuergerät kann beispielsweise verwendet werden, um einen Schrittmotor 15 zu steuern. Es ist in an sich bekannter Weise auf der Oberseite des Motors angeordnet und über die Anschlüsse 4 und 4′ mit dem Motor 15 ver­ bunden (Fig. 7).The control device formed in this way can be used, for example, to control a stepper motor 15 . It is arranged in a manner known per se on the top of the motor and connected via the connections 4 and 4 'to the motor 15 ( FIG. 7).

Ergänzend kann für beispielsweise die Steckkontakte 3 ein Gehäuse 16 vorgese­ hen sein, das nachträglich mit dem Körper 13 verbunden werden kann. Hierzu besitzt der Körper 13 beispielsweise dann eine Einschnürung 17, in die das Stec­ ker-Gehäuse 16 eingeklippst wird. Die Anschlüsse 3 sind dann zusätzlich ge­ schützt und ermöglichen einen problemlosen Anschluß eines nicht gezeigten Stec­ kers am elektronischen Steuergerät 1. Auf diese Weise ergibt sich ein elektroni­ sches Steuergerät, das einfach im Aufbau und in der Herstellung ist und das den­ noch eine hohe mechanische und thermische Stabilität besitzt.In addition, for example the plug contacts 3, a housing 16 can be hen, which can subsequently be connected to the body 13 . For this purpose, the body 13 then has, for example, a constriction 17 , into which the connector housing 16 is clipped. The connections 3 are then additionally protected and enable problem-free connection of a connector (not shown) to the electronic control unit 1 . In this way, there is an electronic control unit which is simple in construction and manufacture and which still has high mechanical and thermal stability.
