Anschlußvorrichtung für eine elektronische SchaltungConnection device for an electronic circuit
Die Erfindung bezieht sich auf eine Anschlußvorrichtung zur Verbindung externer Stromkreise mit einer elektronischen Schaltung auf einem Schaltungsträger.The invention relates to a connection device for connecting external circuits to an electronic circuit on a circuit carrier.
Eine Anschlußvorrichtung zur Verbindung externer Stromkreise mit einer elektronischen Schaltung auf einem Schaltungsträger ist z.B. aus der DE 196 22 445 Cl bekannt. Hier erfolgt der Anschluß über vorgeformte Drahtstifte, die flächig auf Lötpads des Schaltungsträgers in der Weise aufgelötet werden, daß ihre freien Enden, durch ein übergeschobenes Kunststoff-Teil geführt, unmittelbar die Drahtstifte des Anschlußsteckers bilden. Fertigungstechnisch ist diese Anordnung zwar gut handhabbar, jedoch werden zur sicheren Fixierung der Drahtstifte auf dem Schaltungsträger relativ große Lötpads benötigt.A connection device for connecting external circuits with an electronic circuit on a circuit carrier is known, for example, from DE 196 22 445 Cl. Here, the connection is made via pre-formed wire pins, which are soldered flat onto solder pads on the circuit carrier in such a way that their free ends, guided through a plastic part pushed over them, directly form the wire pins of the connector. In terms of manufacturing technology, this arrangement is easy to handle, but relatively large solder pads are required to securely fix the wire pins on the circuit carrier.
Daher liegt der Erfindung die Aufgabe zugrunde, eine Anschlußvorrichtung der obengenannten Art aufzuzeigen, bei der wenig Anschlußfläche auf dem Schaltungsträger benötigt wird und die zugleich in der Fertigung gut handhabbar ist.The invention is therefore based on the object of demonstrating a connection device of the above-mentioned type, in which little connection area is required on the circuit carrier and which is at the same time easy to handle in production.
Die Aufgabe wird gelöst durch ein Isolierstoff-Teil, das kraftschlüssig mit dem Schaltungsträger verbunden ist, in dem metallische Anschlußstifte kraftschlüssig gehaltert sind, deren schaltungsseitige Enden über Bonddrähte mit Bondpads 0 auf dem Schaltungsträger verbunden sind.The task is solved by an insulating material part that is positively connected to the circuit carrier, in which metallic connection pins are held in a force-fitting manner, the circuit-side ends of which are connected to bond pads 0 on the circuit carrier via bonding wires.
Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous further developments of the invention can be found in the dependent claims.
5 Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert.5 An embodiment of the invention is explained in more detail below with reference to a drawing.
