Description
Die Erfindung betrifft ein Verfahren zur elektrisch leitfähigen Kontaktierung einer Leiterplatte.The invention relates to a method for electrically conductive contacting of a printed circuit board.
Aus dem Stand der Technik ist, wie in der
Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zur elektrisch leitfähigen Kontaktierung einer Leiterplatte anzugeben.The invention is based on the object of specifying a method for electrically conductive contacting of a printed circuit board which is improved over the prior art.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren zur elektrisch leitfähigen Kontaktierung einer Leiterplatte mit den Merkmalen des Anspruchs 1.The object is achieved according to the invention by a method for electrically conductive contacting of a printed circuit board having the features of claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous refinements of the invention are the subject matter of the subclaims.
In einem erfindungsgemäßen Verfahren zur elektrisch leitfähigen Kontaktierung einer Leiterplatte, insbesondere aus Kunststoff, wird ein Kontaktstift, insbesondere aus Messing, die Leiterplatte durchdringend, d. h. von einer Flachseite in Richtung einer gegenüberliegenden Flachseite der Leiterplatte, in die Leiterplatte, insbesondere formschlüssig, eingepresst, bis eine Kragenausformung an einem stirnseitigen Ende des Kontaktstifts an einem Boden einer nutartigen Vertiefung in der Leiterplatte anliegt. Dieses stirnseitige Ende wird mit einer in die nutartige Vertiefung gedruckten Leiterbahn, insbesondere aus Silber, bedeckt. Der Kontaktstift wird mit einer Crimphülse vercrimpt. In die Crimphülse wird ein elektrisches Kabel, insbesondere mit einer Kabelendhülse, eingeführt, mit dem Kontaktstift elektrisch leitfähig kontaktiert und mit der Crimphülse vercrimpt. Über dem Kontaktstift, der Crimphülse und zumindest abschnittsweise über dem elektrischen Kabel, insbesondere über der Kabelendhülse, wird ein Schrumpfschlauch abdichtend angeordnet, d. h. aufgeschrumpft. Vorteilhafterweise wird die Leiterplatte bestückt und/oder mit mindestens einer anderen Komponente verklebt, bevor der Kontaktstift mit der Crimphülse vercrimpt wird.In a method according to the invention for electrically conductive contacting of a circuit board, in particular made of plastic, a contact pin, in particular made of brass, penetrates the circuit board, ie. H. from one flat side in the direction of an opposite flat side of the circuit board, pressed into the circuit board, in particular in a form-fitting manner, until a collar formation at a front end of the contact pin rests on a bottom of a groove-like recess in the circuit board. This end is covered with a printed conductor, in particular made of silver, in the groove-like depression. The contact pin is crimped with a crimp barrel. An electrical cable, in particular with a cable end sleeve, is inserted into the crimp sleeve, electrically conductively contacted with the contact pin and crimped with the crimp sleeve. A shrink tube is sealingly arranged over the contact pin, the crimp sleeve and at least in sections over the electrical cable, in particular over the cable end sleeve, ie. H. shrunk. The circuit board is advantageously equipped and / or glued to at least one other component before the contact pin is crimped with the crimp sleeve.
Die Vercrimpung der Crimphülse mit dem Kontaktstift erfolgt insbesondere derart, dass der Kontaktstift in seiner Position in der Leiterplatte durch die Crimphülse verriegelt ist, wobei durch die Crimphülse insbesondere eine Bewegung des Kontaktstifts in Längsrichtung des Kontaktstifts unterbunden oder zumindest eingeschränkt ist. Die Crimphülse verhindert dabei insbesondere ein Zurückdrücken des Kontaktstifts entgegen der Einpressrichtung, wodurch insbesondere eine Kontaktierung des Kontaktstifts zu Leitpasten und/oder zur Leiterbahn am stirnseitigen Ende des Kontaktstifts in Funktion gehalten wird.The crimping of the crimp barrel with the contact pin takes place in particular in such a way that the contact pin is locked in its position in the circuit board by the crimp barrel, with the crimp barrel in particular preventing or at least restricting movement of the contact pin in the longitudinal direction of the contact pin. The crimp sleeve in particular prevents the contact pin from being pushed back against the press-in direction, which in particular keeps contact between the contact pin and conductive pastes and / or the conductor track at the front end of the contact pin in operation.
Mittels der erfindungsgemäßen Lösung kann bei industriell hergestellten Leiterplatten, insbesondere aus Kunststoff, mit insbesondere siebgedruckten Leiterbahnen eine sinnvolle und umwelteinflussstabile elektrisch leitfähige Kontaktierung für Kabel erzeugt werden. Insbesondere wird durch diese erfindungsgemäße Lösung ein durch Temperaturwechselwirkungen und Umwelteinflüsse verursachtes Lösen der elektrisch leitenden Verbindung des Kabels verhindert.By means of the solution according to the invention, in industrially manufactured circuit boards, in particular made of plastic, with in particular screen-printed conductor tracks, a sensible and environmentally stable electrically conductive contact for cables can be produced. In particular, this solution according to the invention prevents the electrically conductive connection of the cable from loosening caused by temperature interactions and environmental influences.
Bei einer direkten elektrisch leitfähigen Kontaktierung der Leiterbahnen mit dem Kabel oder anderen Verbindungselementen würde aufgrund der verschiedenen Wärmeausdehnungskoeffizienten der beteiligten Materialien und durch eine geringe Verbindungskraft zu den Leiterbahnen bereits eine thermisch verursachte Bewegung ausreichen, um die Verbindung zu trennen und somit zu Fehlern in der elektrischen Kontaktierung zu führen. Dies wird durch die erfindungsgemäße Lösung vermieden.In the case of direct electrically conductive contact between the conductor tracks and the cable or other connecting elements, due to the different coefficients of thermal expansion of the materials involved and a low connection force to the conductor tracks, a thermally induced movement would be sufficient to separate the connection and thus to errors in the electrical contact respectively. This is avoided by the solution according to the invention.
Die erfindungsgemäße Lösung wird beispielsweise zur elektrisch leitfähigen Kontaktierung einer Leiterplatte eines Emblems, insbesondere eines beleuchteten Emblems, insbesondere eines Markenemblems eines Fahrzeugherstellers, welches an einem Fahrzeug anbringbar ist, verwendet.The solution according to the invention is used, for example, for electrically conductive contacting of a printed circuit board of an emblem, in particular an illuminated emblem, in particular a brand emblem of a vehicle manufacturer, which can be attached to a vehicle.
