Description

Elektrisches GerätElectric device
Stand der TechnikState of the art
Die Erfindung betrifft ein elektrisches Gerät mit den Merkmalen des Oberbegriffs des unabhängigen Anspruchs 1.The invention relates to an electrical device with the features of the preamble of independent claim 1.
Aus der DE 1 022 968 AI ist ein elektrisches Gerät bekannt, welches ein mit einem Deckel als zweites Gehäuseteil ver- schließbares erstes Gehäuseteil aufweist, in dem eine mit e- lektrischen/elektronischen Bauelementen versehene Leiterplatte angeordnet. Das erste Gehäuseteil ist mit Kontaktelementen versehen, welche mit dem Anschluss des Gerätes elektrisch verbunden sind. Beim Einbau der Leiterplatte dringen nach Innen abstehende Enden der Kontaktelemente durch Kontaktoffnungen der Leiterplatte, so dass die Leiterplatte mit dem Anschluss des Gerätes elektrisch verbunden ist. Anschließend wird das zweite Gehäuseteil auf das erste Gehäuseteil aufgesetzt und der Gehäuseinnenraum verschlossen.From DE 1 022 968 AI an electrical device is known which has a first housing part which can be closed with a lid as the second housing part and in which a printed circuit board provided with electrical / electronic components is arranged. The first housing part is provided with contact elements which are electrically connected to the connection of the device. When the circuit board is installed, ends of the contact elements which protrude inward penetrate through contact openings in the circuit board, so that the circuit board is electrically connected to the connection of the device. The second housing part is then placed on the first housing part and the housing interior is closed.
Vorteile der ErfindungAdvantages of the invention
Bei dem erfindungsgemäßen elektrischen Gerät mit den kennzeichnenden Merkmalen des Anspruchs 1 ist eine mit elektri- sehen/elektronischen Bauelementen versehene Trägerplatte vorteilhaft an dem zweiten Gehäuseteil festgelegt, so dass durch Aufsetzen des zweiten Gehäuseteils auf das erste Gehäuseteil vorteilhaft gleichzeitig die elektrische Verbindungen zwischen den Kontaktelementen und der Trägerplatte hergestellt werden. Somit entfällt die aufwendige Montage, bei der zunächst die Trägerplatte in das Gehäuse eingebaut wird und anschließend erst in einem separaten Arbeitsschritt die beiden Gehäuseteile miteinander verbunden werden. Das erfindungsgemäße elektrische Gerät ist daher einfach und kostensparend herstellbar. Da die Trägerplatte an dem zweiten Gehäuseteil festgelegt ist, kann die elektrische Verbindung vom Geräteanschluss zur Trägerplatte einfacher und zuverlässiger hergestellt werden, da die zum Einpressen benötigte Kraft auf das zweite Gehäuseteil wirkt und die Träger- platte gleichzeitig durch das zweite Gehäuseteil mechanisch stabilisiert wird. Ein Bruch der Trägerplatte wird dabei vorteilhaft vermieden.In the electrical device according to the invention with the characterizing features of claim 1 is a support plate provided with electrical / electronic components advantageously fixed to the second housing part, so that by placing the second housing part on the first housing part, the electrical connections between the contact elements and the carrier plate are advantageously produced at the same time. This eliminates the complex assembly, in which the carrier plate is first installed in the housing and only then are the two housing parts connected to one another in a separate working step. The electrical device according to the invention is therefore simple and inexpensive to manufacture. Since the carrier plate is fixed to the second housing part, the electrical connection from the device connection to the carrier plate can be established more simply and reliably, since the force required for pressing in acts on the second housing part and the carrier plate is simultaneously mechanically stabilized by the second housing part. A breakage of the carrier plate is advantageously avoided.
Vorteilhafte Ausführungsbeispiele und Weiterentwicklungen der Erfindung werden durch die in den abhängigen Ansprüchen angegebenen Merkmale ermöglicht.Advantageous exemplary embodiments and further developments of the invention are made possible by the features specified in the dependent claims.
Besonders vorteilhaft ist die Anwendung von Ultraschall zum Dichtschweißen der Verbindungsstelle zwischen dem ersten Ge- häuseteil und dem zweiten Gehäuseteil. Die Ultraschalleinwirkung reduziert die zum Einpressen der Kontaktelemente in die Kontaktoffnungen der Trägerplatte benötigte Kraft vorteilhaft auf etwa 20%. Aufgrund der reduzierten Einpresskraft kann das zweite Gehäuseteil vereinfacht mit dem ersten Gehäuseteil verscheißt werden, was vorteilhaft ebenfalls durch Ultraschall erfolgt. Somit kann in einem gemeinsamen Arbeitsschritt das zweite Gehäuseteil auf das erste Gehäuseteil aufgesetzt werden, die elektrische Kontaktierung zwischen Trägerplatte und Geräteanschluss hergestellt werden und außerdem der Übergangsbereich von ersten und zweiten Gehäuseteil abgedichtet werden.The use of ultrasound for sealing welding the connection point between the first housing part and the second housing part is particularly advantageous. The effect of ultrasound advantageously reduces the force required to press the contact elements into the contact openings of the carrier plate to approximately 20%. Because of the reduced press-in force, the second housing part can be welded to the first housing part in a simplified manner, which is also advantageously done by ultrasound. Thus, in a common working step, the second housing part can be placed on the first housing part, and the electrical contact between the carrier plate and the device connection can be established and also the transition region of the first and second housing parts are sealed.
Durch die Ausbildung eines Kragens an dem zweiten Gehäuse- teil und die Ausbildung eines Vorsprungs an einer dem zweiten Gehäuseteil zugewandte Stirnseite einer Wandung des ersten Gehäuseteils können die beiden Gehäuseteile besonders zuverlässig miteinander verschweißt werden.The two housing parts can be welded to one another particularly reliably by the formation of a collar on the second housing part and the formation of a projection on an end face of a wall of the first housing part facing the second housing part.
Besonders vorteilhaft ist weiterhin, dass durch die Ultraschalleinwirkung im Kontaktbereich von Kontaktelementen und Kontaktoffnungen eine verlötungsartiger Kontaktzone entsteht, wodurch die Zuverlässigkeit der elektrischen Verbindung zwischen der Trägerplatte und dem Geräteanschluss er- höht wird.It is also particularly advantageous that the action of ultrasound in the contact area of contact elements and contact openings creates a soldering-like contact zone, which increases the reliability of the electrical connection between the carrier plate and the device connection.

Bei dem Gerät kann es sich aber auch um einen beliebigen anderen Sensor oder um ein Steuergerät handeln. Das elektrische Gerät umfasst wenigstens ein erstes Gehäuseteil 1 und ein zweites Gehäuseteil 2, welche beispielsweise als' Spritzgussteile aus Kunststoff gefertigt sind. An dem ersten Gehäu- seteil 1 ist ein Anschluss 4 als Steckerteil ausgebildet. Elektrische Kontaktelemente 5 sind an dem ersten GehäuseteilIn Fig. 1, an electrical device is shown, which is designed in this embodiment as a rotation angle sensor. However, the device can also be any other sensor or a control device. The electrical device comprises at least a first housing part 1 and a second housing part 2, which are made for example as' injection-molded parts made of plastic. On the first housing part 1, a connection 4 is designed as a plug part. Electrical contact elements 5 are on the first housing part
1 angeordnet. Diese können beispielsweise mit Kunststoff umspritzt sein oder in das erste Gehäuseteil eingepresst sein oder in anderer geeigneter Weise an dem ersten Gehäuseteil festgelegt sein. Erste Enden 11 der Kontaktelemente 5 bilden Steckkontakte zum Anschluss eines entsprechend ausgebildeten Gegensteckers. Die Kontaktelemente 5 können selbstverständlich auch mit separaten Steckkontakten eines solchen Steckerteil elektrisch verbunden sein. Die zweiten Enden 12 der Kon- taktelemente 5 sind in den Gehäuseinnenraum geführt und dort in eine gemeinsame Richtung abgebogen, welche mit der Aufsetzrichtung eines zweiten Gehäuseteils 2 auf das erste Gehäuseteil 1 übereinstimmt. Das zweite Gehäuseteil 2 ist in diesem Ausführungsbeispiel mit einem zu dem ersten Gehäuse- teil 1 hin abstehenden Kragen 13 versehen ist, welcher einen Vorsprung 14 an der dem zweiten Gehäuseteil 2 zugewandten Stirnseite der Wandung 8 des ersten Gehäuseteils 1 umfasst.1 arranged. These can, for example, be extrusion-coated with plastic or pressed into the first housing part or fixed in another suitable manner to the first housing part. First ends 11 of the contact elements 5 form plug contacts for connecting a correspondingly designed mating plug. The contact elements 5 can of course also be electrically connected to separate plug contacts of such a plug part. The second ends 12 of the contact elements 5 are guided into the interior of the housing and are bent there in a common direction which corresponds to the direction in which a second housing part 2 is placed on the first housing part 1. In this exemplary embodiment, the second housing part 2 is provided with a collar 13 projecting towards the first housing part 1, which comprises a projection 14 on the end face of the wall 8 of the first housing part 1 facing the second housing part 2.
In dem Gehäuseinnenraum ist eine als Leiterplatte oder kera- misches Hybrid ausgebildete Trägerplatte 3 angeordnet, welche mit elektrischen und/oder elektronischen Bauelementen 9 versehen ist. Die Trägerplatte 3 ist mit dem zweiten GehäuseteilArranged in the interior of the housing is a carrier plate 3 designed as a printed circuit board or ceramic hybrid, which is provided with electrical and / or electronic components 9. The carrier plate 3 is with the second housing part
2 fest verbunden. Beispielsweise kann die Trägerplatte 3 auf das zweite Gehäuseteil 2 aufgeklebt sein oder mittels anderer geeigneter Befestigungsmittel an dem zweiten Gehäuseteil 2 festgelegt sein.2 firmly connected. For example, the carrier plate 3 can be glued to the second housing part 2 or fixed to the second housing part 2 by means of other suitable fastening means.
Fig. 2 zeigt einen vergrößerten Ausschnitt aus Fig. 1. Die Trägerplatte 3 weist elektrische Kontaktoffnungen 6 bei- spielsweise in Form von Durchkontaktierungen auf, welche Kontaktoffnungen über Leiterbahnen der Trägerplatte 3 mit den Bauelementen 9 elektrisch verbunden sind. Beim Aufsetzen des mit der Trägerplatte 3 versehenen zweiten Gehäuseteils 2 werden die zweiten Enden 12 der Kontaktelemente in die Kontakt- Öffnungen 6 elektrisch kontaktierend eingepresst, wobei zum Einspressen der Kontaktelemente 5 eine bestimmte Einpress- kraft erforderlich ist. In dem zweiten Gehäuseteil 2 können unter der Trägerplatte 3 noch Aussparungen 15 ausgebildet sein, welche die auf der von dem ersten Gehäuseteil 1 abge- wandten Seite der Trägerplatte 3 abstehenden Enden der Kontaktelemente 5 aufnehmen.FIG. 2 shows an enlarged detail from FIG. 1. The carrier plate 3 has electrical contact openings 6, for example in the form of plated-through holes, which contact openings are electrically connected to the components 9 via conductor tracks of the carrier plate 3. When the second housing part 2 provided with the carrier plate 3 is placed on it, the second ends 12 of the contact elements are pressed into the contact openings 6 in an electrically contacting manner Pressing the contact elements 5 a certain press-in force is required. In the second housing part 2, recesses 15 can also be formed under the carrier plate 3, which receive the ends of the contact elements 5 which protrude on the side of the carrier plate 3 facing away from the first housing part 1.
Durch Einstrahlung von Ultraschallwellen, beispielsweise von der dem ersten Gehäuseteil 1 abgewandten Seite des zweiten Gehäuseteils 2 aus, kann einerseits diese Einspresskraft verringert werden und andererseits das zweite Gehäuseteil 2 mit dem ersten Gehäuseteil 1 im Bereich des Vorsprungs 14 und des Kragens 13 dicht verschweißt werden. Durch das an sich bekannte Ultraschallschweißen wird dabei die zum Einpressen der Kontaktelemente benötigte Kraft vorteilhaft auf bis zu 20% verringert, wodurch das Verschweißen des zweiten Gehäuseteils mit dem ersten Gehäuseteil stark erleichtert wird.By irradiation of ultrasound waves, for example from the side of the second housing part 2 facing away from the first housing part 1, this injection force can be reduced on the one hand and on the other hand the second housing part 2 can be tightly welded to the first housing part 1 in the region of the projection 14 and the collar 13. The ultrasonic welding known per se advantageously reduces the force required to press in the contact elements to up to 20%, which greatly simplifies the welding of the second housing part to the first housing part.
Vorteilhaft entsteht durch den Ultraschall gleichzeitig eine verlötungsartige Kontaktzone 7 im Kontaktierungsbereich vonThe ultrasound advantageously simultaneously creates a soldering-like contact zone 7 in the contacting area of
Kontaktelementen 5 und Kontaktoffnungen 6, wodurch die Zuverlässigkeit der elektrischen Verbindung erhöht wird. Contact elements 5 and contact openings 6, which increases the reliability of the electrical connection.
