Description

Die Erfindung betrifft einen Lötstützpunkt für Bauelemente auf Leiterplatten, der mit mindestens einem Schenkel in mit Leiterbahnen verbundene öffnungen der Leiterplatte eingesetzt ist, durch den er mit der Leiterplatte mechanisch und mit den Leiterbahnen elektrisch leitend verbunden ist sowie eine trichterförmige Buchse aufweist, welche durch ein Loch der Leiterplatte in den Lötbereich ragt und durch die sich eine Anschlußelektrode des Bauelementes erstreckt.The invention relates to a soldering post for components on circuit boards, with at least one Leg is inserted into openings of the circuit board connected to conductor tracks, through which it connects to the circuit board mechanically and electrically conductively connected to the conductor tracks and a funnel-shaped Has socket which protrudes through a hole in the circuit board in the soldering area and through which a connection electrode of the component extends.

Bei einem solchen bekannten Lötstützpunkt (US-PS 27 30 690) ragt der Schenkel zusammen mit einer Anschlußelektrode eines anderweitig auf der Leiterplatte angeordneten Bauelements in eine mit einer Leiterbahn verbundene öffnung, in der Schenkel und Anschlußelektrode angelötet sind. Zwei andere Schenkel des Lötstützpunktes sind mit Rastlappen versehen, durch welche der Lötstützpunkt an der Leiterplatte verrastet und somit mechanisch befestigt ist Die beiden durch einen Schlitz der Leiterplatte gesteckten und verrasteten Schenkel haben winklig aufeinanderzu gebogene Randabschnitte, zwischen welche eine Anschlußelektrode eines Bauelements lösbar geschoben ist. Anschlußelektrode und Lötstützpunkt sind somit nur als Steckverbindung miteinander verbunden. Eine feste Verbindung beispielsweise durch Löten erlaubt nicht mehr das erforderliche einfache Auswechseln des Bauelements, wenn es wie bei der bekannten Anordnung als Röhre ausgebildet ist. Da diese Steckverbindung sich an der Unterseite der Leiterplatte erstreckt, an welcher sich der Lötbereich für eine Maschinenlötung befindet, bei der alle Lötstellen in einem Lötgang hergestellt werden, kann bei Verwendung des bekannten Lötstützpunktes auch keine wirtschaftliche Maschinenlötung erfolgen.In such a known soldering post (US-PS 27 30 690) the leg protrudes together with a connection electrode of a component arranged otherwise on the circuit board into one with a conductor track connected opening in which the leg and connection electrode are soldered. Two other legs of the soldering post are provided with locking tabs through which the soldering post is locked on the circuit board and thus mechanically fastened. The two were inserted and locked through a slot in the circuit board Legs have edge sections bent towards one another at an angle, between which a connection electrode is Component is releasably pushed. Connection electrode and soldering post are therefore only a plug-in connection connected with each other. A fixed connection, for example by soldering, no longer allows the necessary simple replacement of the component, if it is as with the known arrangement as a tube is trained. Since this connector extends on the underside of the circuit board on which the soldering area is for machine soldering, in which all soldering points are made in one soldering process, If the known soldering post is used, no economical machine soldering can be carried out either.

Außerdem ist eine feste Verbindung bekannt, bei der die elektronischen Bauelemente mit Anschlußdrähten versehen sind und von Hand verdrahtet und mit Handlötkolben mit den zugehörigen Leiterbahnen elektrisch leitend verbunden werden. Dadurch ergeben sich erhöhte Montagekosten. Außerdem sind zum Vermeiden von unterschiedlichen Wärmeausdehnungen entsprechend der verschiedenen Werkstoffe sich relativ stark erwärmende elektronische Bauelemente wie Leistungstransistoren nicht auf der Leiterplatte angeordnet, was zu verhältnismäßig großem Platzbedarf bei elektronischen Steuergeräten führt.In addition, a fixed connection is known in which the electronic components with connecting wires are provided and wired by hand and electrically with the hand soldering iron with the associated conductor tracks be conductively connected. This results in increased assembly costs. Also are to be avoided of different thermal expansions corresponding to the different materials are relatively strong warming electronic components such as power transistors are not arranged on the circuit board, what leads to a relatively large space requirement for electronic control units.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Lötstützpunkt für Bauelemente zum Verbinden mil Leiterbahnen einer Leiterplatte zu schaffen, bei der unabhängig von den Anschlußabmessungen und der durch Werkstoffausdehnungen hervorrufenden Erwärmung des elektronischen Bauelementes das Bauelement auf der Leiterplatte angeordnet werden kann und die elektrisch leitende Verbindung mit den zugehörigen Leiterbahnen zusammen mit einem maschinellen Lötvorgang hergestellt wird, wobei die Lötstellen frei von mechanischen Spannungen sein sollen.The invention is therefore based on the object of providing a soldering post for components for connecting mil To create conductor tracks of a circuit board, regardless of the connection dimensions and the through Material expansion causing heating of the electronic component on the component the circuit board can be arranged and the electrically conductive connection with the associated conductor tracks is produced together with a machine soldering process, the soldering points being free of mechanical Tensions should be.

Erfindungsgemäß wird die Aufgabe dadurch gelöst daß die trichterförmige Buchse in dem Loch der Leiterplatte seitlich frei bewegbar ist und durch einen federnden Kontaktarm am Schenkel gehaltert ist.According to the invention the object is achieved in that the funnel-shaped socket in the hole in the circuit board is laterally freely movable and is supported by a resilient contact arm on the leg.

Durch den federnden Kontaktarm, an dem die Anschlußelektrode durch den Maschinenlötgang starr verbunden ist sowie durch das große Loch der Leiterplatte, durch welche das trichterförmige Ende des Konlaktarms ragt, hat der Kontaktarm genügend Bewegungsmöglichkeiten, um eventuell auf die Lötstelle wirkende mechanische Spannungen federnd abzufangen. Ein Ausführungsbeispiel der Verbindung nach der Erfindung ist in der Zeichnung wiedergegeben. Sie zeigt in Fig. 1 einen Teil einer Leiterplatte, auf der ein Lötstützpunkt angeordnet ist, in räumlicher Darstellung, Fig. 2 den Teil der Leiterplatte in Ansicht von der Lötseite.By the resilient contact arm, to which the connection electrode is rigidly connected by the machine soldering path is as well as through the large hole in the circuit board through which the funnel-shaped end of the Konlaktarms protrudes, the contact arm has enough freedom of movement to possibly affect the solder joint to absorb mechanical stresses resiliently. An embodiment of the connection according to the invention is shown in the drawing. It shows in Fig. 1 part of a circuit board on which a soldering post is arranged, in a three-dimensional representation, Fig. 2 the part of the circuit board in view of the Solder side.

Eine Leiterplatte 1 ist mit öffnungen 2 versehen sowie mit Löchern 3 und Befestigungslöchern 4. Die öffnungen 2 (Fig.2) liegen in Anschlußstellen 5 von Leiterbahnen 6, welche auf der Leiterplatte 1 ein- oder beidseitig aufgetragen sind.A circuit board 1 is provided with openings 2 as well with holes 3 and fastening holes 4. The openings 2 (FIG. 2) are located in connection points 5 of conductor tracks 6, which are applied to one or both sides of the circuit board 1.

Ein elektronisches Bauelement in Form eines Leistungstransistors 7 ist auf der Leiterplatte 1 mechanisch befestigt durch Schrauben oder Niete, welche in den Befestigungslöchern 4 sitzen. Jede Anschlußelektrode 8 des Leistungstransistors 7 ragt durch ein Loch 3 der Leiterplatte lin den Bereich eines Maschinenlötganges an der Unterseite der Leiterplatte 1.An electronic component in the form of a power transistor 7 is mechanically on the circuit board 1 fastened by screws or rivets which sit in the fastening holes 4. Each terminal electrode 8 of the power transistor 7 protrudes through a hole 3 in the circuit board lin the area of a machine soldering process on the underside of the circuit board 1.

Ein Lötstützpunkt ist als im wesentlichen U-förmige Kontakfeder 9 mit zwei Schenkeln 10 ausgebildet. Die Schenkel 10 laufen in Zapfen 11 aus, welche in die Öffnungen 2 gesteckt sind und mit ihren Enden ebenfalls an der Unterseite der Leiterplatte 1 in den Lötbereich ragen. Ein federnder Kontaktarm 12 ist an der Kontaktfeder 9 derart angebogen, daß er mit einem Verbindungsabschnitt 13 zwischen den Schenkeln 10 ebenfalls M-förmig verbunden ist. Der Kontaktarm 12 ist an seinem freien Ende zu einer trichterförmigen Buchse 14 geformt. Die trichterförmige Buchse 14 ragt durch das Loch 3 der Leiterplatte 1 auch in den Lötbereich. Die Anschlußelektrode 8 des Leistungstransistors 7 erstreckt sich durch die Buchse 14 bis über die Unterseite der Leiterplatte 1 hinaus. Jeder Anschlußelektrode 8 ist eine Kontaktfeder9 zugeordnet.A soldering post is designed as an essentially U-shaped contact spring 9 with two legs 10. the Legs 10 run out in pins 11 which are inserted into the openings 2 and also with their ends the underside of the circuit board 1 protrude into the soldering area. A resilient contact arm 12 is on the contact spring 9 bent in such a way that it is connected to a connecting portion 13 is also connected in an M-shape between the legs 10. The contact arm 12 is on his free end formed into a funnel-shaped socket 14. The funnel-shaped socket 14 protrudes through the Hole 3 of the circuit board 1 also in the soldering area. The connection electrode 8 of the power transistor 7 extends through the socket 14 to over the underside of the circuit board 1 also. Each terminal electrode 8 is a contact spring9 assigned.

Die Bauelemente einer Steuerelektronik, die Leistungstransistoren 7 der Leistungsstufe und sonstige elektrischen Bauelemente sind auf der Leiterplatte 1 angeordnet und mit den Leiterbahnen 6 durch einen einzigen Maschinenlötgang elektrisch leitend verbunden. Dabei steigt Lötmittel 15 in die Buchse 14 und bildet dort wie unterhalb des Bereichs um die kleinere öffnung der Buchse 14 eine gute elektrisch leitende Verbindung zwischen der Anschlußelektrode 8 und dem Kontaktarm 12 der Kontaktfeder 9. Die elektrisch leitende Verbindung zwischen der Kontaktfeder 9 und der br> zugehörigen Leiterbahn 6 erfolgt über die Schenkel 10 und Zapfen ti, welche durch Lötmittel mit den Anschlußstellen 5 der Leiterbahnen 6 verbunden sind. Leitungstransistoren 7 gehören zu den sich relativThe components of an electronic control system, the power transistors 7 of the power stage and other electrical components are arranged on the circuit board 1 and are electrically conductively connected to the conductor tracks 6 by a single machine soldering path. The solder 15 rises into the socket 14 and forms a good electrically conductive connection between the connection electrode 8 and the contact arm 12 of the contact spring 9, as below the area around the smaller opening of the socket 14. The electrically conductive connection between the contact spring 9 and the b The associated conductor track 6 takes place via the legs 10 and pins ti, which are connected to the connection points 5 of the conductor tracks 6 by solder. Line transistors 7 belong to the relative

stark erwärmenden elektronischen Bauelementen. Sie verursachen bei Temperaturwechsel unterschiedliche Wärmeausdehnung der sie unmittelbar umgehenden verschiedenen Werkstoffe wie der Kontaktfeder 9 und der Leiterplatte 1. Durch die Federwirk'jng des Kontaktarmes 12 in Richtung der Längsachse der Anschluße'ektrode 8 werden durch die unterschiedliche Ausdehnung bei Temperaturwechsel hervorgerufene Spannungen kompensiert. Dadurch ist es möglich, sich relativ stark erwärmende elektronische Bauelemente 7 direkt auf der Leiterplatte 1 anzuordnen. Zum Herstellen der elektrisch leitenden Verbindungen zwischen den Leistungstransistoren 7 und den Leiterbahnen 6 entfällt sowohl das lohnintensive Verdrahten von Hand als auch das Löten mit Handkolben. Die Zapfen 11 zum Kontaktieren an den Leiterbahnen 6 können außerdem unabhängig von den Abmessungen der Anschlußelektroden 8 den Anschlußstellen 5 und Leiterbahnen 6 angepaßt werden.strongly heating electronic components. They cause different effects when there is a change in temperature Thermal expansion of the various materials immediately bypassing them, such as the contact spring 9 and of the circuit board 1. Due to the spring action of the contact arm 12 in the direction of the longitudinal axis of the connection electrode 8 are due to the different expansion Stresses caused by temperature changes are compensated. This makes it possible to look relative To arrange strongly heating electronic components 7 directly on the circuit board 1. To produce the Electrically conductive connections between the power transistors 7 and the conductor tracks 6 are omitted both the labor-intensive manual wiring and soldering with hand-held pistons. The pins 11 for contact on the conductor tracks 6 can also be independent of the dimensions of the connection electrodes 8 the connection points 5 and conductor tracks 6 are adapted.
