Description

Anordnung mit einem Kontaktelement Arrangement with a contact element
Die Erfindung betrifft eine Anordnung mit einer Leiterplatte, welche mit mindestens einer Leiterbahn und einem Kontaktelement zur Herstellung einer elektrischen Verbindung zwischen einem elektrischen Leiter und einer vorgegebenen Leiterbahn auf dieser Leiterplatte versehen ist.The invention relates to an arrangement with a circuit board, which is provided with at least one conductor track and a contact element for establishing an electrical connection between an electrical conductor and a predetermined conductor track on this circuit board.
Bei verschiedenen Anwendungen, z. B. in der Kraftfahrzeugtechnik, auf einem Schiff oder in der Luftfahrt ist es er orderlich, eine vorgegebene Leiterbahn, welche sich auf einer Leiterplatte befindet, mit einem von außen kommenden elektrischen Leiter mechanisch und elektrisch sicher zu verbinden. Dieser elektrische Leiter kann z. B. zur Stromversorgung dienen, und in diesem Fall darf im Betrieb des Fahrzeugs keine Unterbrechung der Stromversorgung auftreten.In various applications, e.g. B. in automotive engineering, on a ship or in aviation, it is orderable to connect a predetermined conductor track, which is located on a circuit board, with an external electrical conductor mechanically and electrically safely. This electrical conductor can, for. B. serve for power supply, and in this case, no interruption of the power supply may occur in the operation of the vehicle.
Diese Verbindung kann auch zur Verbindung mit dem Elektromotor einer sicherheitsrelevanten Applikation dienen, z. B. mit einem Motor, der von der Leiterplatte aus gesteuert wird. Das kann z. B. eine Applikation sein, bei der eine Bewegung elektrisch gesteuert wird (x-by-wire). Auch hier wird eine zuverlässige Verbindung während der ganzen Lebensdauer des Kraftfahrzeugs, Flugzeugs, Schiffs oder dgl. gefordert.This connection can also be used to connect to the electric motor of a safety-relevant application, e.g. B. with a motor that is controlled from the circuit board. That can e.g. B. be an application in which a movement is electrically controlled (x-by-wire). Here, too, a reliable connection is required over the entire service life of the motor vehicle, aircraft, ship or the like.
Zusätzlich ist zu berücksichtigen, dass solche elektrischen Verbindungen möglichst automationsgerecht ausgeführt werden müssen, damit ihre Herstellung / Montage preiswert möglich ist.In addition, it must be taken into account that such electrical connections must be carried out as automation-compatible as possible so that their manufacture / assembly is possible at low cost.
Es ist deshalb eine Aufgabe der Erfindung, eine neue Anordnung der eingangs genannten Art bereit zu stellen.It is therefore an object of the invention to provide a new arrangement of the type mentioned in the introduction.
Nach der Erfindung wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 1.According to the invention, this object is achieved by the subject matter of claim 1.
Durch die Erfindung erhält man zwischen Leiterplatte und Kontaktelement eine zuverlässige mechanische und elektrische Verbindung, da die Beinchen in die Ausnehmungen der Leiterplatte eingepresst werden (Einpresstechnik). Diese Ausnehmungen sind über ihre Metallisierung elektrisch mit den Leiterbahnen der Leiterplatte und der dort befindlichen Schaltung verbunden, und sie sind durch das Einpressen elektrisch und mechanisch mit den Beinchen des Kontaktelements verbunden. Letzteres ermöglicht seinerseits eine zuverlässige Verbindung mit dem von außen kommenden elektrischen Leiter.The invention provides a reliable mechanical and electrical connection between the printed circuit board and the contact element, since the legs fit into the recesses in the PCB are pressed in (press-in technology). These recesses are electrically connected via their metallization to the conductor tracks of the printed circuit board and the circuit located there, and they are electrically and mechanically connected to the legs of the contact element by being pressed in. The latter in turn enables a reliable connection to the electrical conductor coming from outside.
Das Kontaktelement ist also schon durch die Einpresstechnik elektrisch mit der vorgegebenen Leiterbahn verbunden, und zusätzlich erhält man eine flächige Lötstelle zwischen ihm und der Leiterbahn. Im sog. Reflow-Verfahren wird also eine Lötverbindung zwischen dem Kontaktelement und der Leiterbahn hergestellt, d. h. bei der Erwärmung der Leiterplatte im Reflow-Ofen kann das Lot an alle gewünschten Stellen gelangen. Diese Lötverbindungen bilden auch, zusätzlich zu der durch die Einpresstechnik entstandenen mechanischen und elektrischen Verbindung, eine sichere elektrische Verbindung und unterstützen die durch das Einpressen entstandene mechanische Verbindung. Trotz kostenoptimaler Prozesse erhält man so eine hohe funktionale Sicherheit der Verbindung zwischen Kontaktelement und Leiterplatte / Leiterbahn, und zwar elektrisch und mechanisch.The contact element is thus already electrically connected to the specified conductor track by the press-in technique, and in addition a flat solder joint is obtained between it and the conductor track. In the so-called reflow process, a soldered connection between the contact element and the conductor track is thus established, i. H. when the circuit board is heated in the reflow oven, the solder can get to any desired location. In addition to the mechanical and electrical connection created by the press-in technology, these soldered connections also form a secure electrical connection and support the mechanical connection created by the pressing. Despite cost-optimal processes, this provides a high level of functional reliability of the connection between the contact element and the printed circuit board / conductor track, namely electrically and mechanically.
Bei der Erfindung steht also die Überlegung im Vordergrund, eine Verbindung zu schaffen, die sehr sicher und zuverlässig ist und deshalb eine gewisse Redundanz aufweist.In the case of the invention, the focus is on creating a connection that is very secure and reliable and therefore has a certain redundancy.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den im folgenden beschriebenen und in der Zeichnung dargestellten, in keiner Weise als Einschränkung der Erfindung zu verstehenden Ausführungsbeispielen, sowie aus den übrigen Unteransprüchen. Es zeigt:Further details and advantageous developments of the invention result from the exemplary embodiments described below and shown in the drawing, which are in no way to be understood as a restriction of the invention, and from the remaining subclaims. It shows:

Fig. 7 eine Darstellung einer Leiterplatte mit dem Kontaktelement der Fig. 6.FIG. 7 shows a circuit board with the contact element of FIG. 6.
Fig. 1 zeigt eine Leiterplatte 20, auf der sich eine Leiterbahn 22 befindet, die gewöhnlich aus verzinntem Kupfer besteht. Oberhalb der Leiterbahn 22 sind in Fig. 1 drei Bohrungen 24, 26, 28 vorgesehen, und unterhalb von ihr zwei Bohrungen 30, 32.Fig. 1 shows a circuit board 20 on which there is a conductor track 22, which usually consists of tinned copper. Three bores 24, 26, 28 are provided above the conductor track 22 in FIG. 1, and two bores 30, 32 below it.
Gemäß Fig. 2 werden in diese fünf Bohrungen 24 bis 32 die fünf Beinchen 34, 36, 38, 40, 42 eines Kontaktelements 44 eingepresst. Durch das Einpressen wird das Kontaktelement 44 in der gewünschten Lage an der Leiterplatte 20 festgehalten. Das Kontaktelement 44 besteht gewöhnlich aus einer Kupferlegierung, oder aus Kupfer, Messing oder dgl. Die Leiterbahn 22 ist weitgehend an die Form des Kontaktelements 44 angepasst, um eine großflächige Verlötung zu ermöglichen.2, the five legs 34, 36, 38, 40, 42 of a contact element 44 are pressed into these five bores 24 to 32. By pressing in, the contact element 44 is held in the desired position on the printed circuit board 20. The contact element 44 usually consists of a copper alloy, or of copper, brass or the like. The conductor track 22 is largely adapted to the shape of the contact element 44 in order to enable large-area soldering.
Wie man aus Fig. 4 klar erkennt, haben die Beinchen 34, 36, 38 bevorzugt eine identische Form. Z. B. hat das Beinchen 38 ein freies Ende 37, und es hat im Bereich dieses freien Endes 37 eine reduzierte Breite 39, so dass es damit beim Bestücken der Leiterplatte 20 leicht in die Öffnung 28 eingeführt und eingepresst werden kann. In seinem in Fig. 4 oberen Teil hat das Beinchen 38 eine Breite 41, die so bemessen ist, dass des in die Öffnung 28 eingepresst werden muss, d. h. seine Breite 41 übersteigt den Durchmesser D (Fig. 1) der Bohrung 28, so dass man bei der Montage einen Presssitz erhält, der eine gute mechanische Verbindung ergibt. Die Bohrungen 24 bis 32 sind zumindest an einem Ende metallisiert, z. B. mit Kupfer, um eine gute Einpressverbindung und damit eine gute mechanische und zudem elektrisch leitende Verbindung zu erhalten.As can be clearly seen from FIG. 4, the legs 34, 36, 38 preferably have an identical shape. For example, the leg 38 has a free end 37, and it has a reduced width 39 in the region of this free end 37, so that it can be easily inserted and pressed into the opening 28 when the printed circuit board 20 is fitted. In its upper part in FIG. 4, the leg 38 has a width 41 which is dimensioned such that it has to be pressed into the opening 28, i. H. its width 41 exceeds the diameter D (FIG. 1) of the bore 28, so that a press fit is obtained during assembly, which results in a good mechanical connection. The bores 24 to 32 are metallized at least at one end, e.g. B. with copper to get a good press-fit connection and thus a good mechanical and also electrically conductive connection.
Wie sich aus Fig. 2 bis 4 ergibt, kann das Kontaktelement 44 an seiner in Fig. 2 oberen Seite drei Beinchen 34, 36, 38 und an seiner unteren Seite zwei Beinchen 40, 42 aufweisen. Alle Beinchen sind elektrisch und mechanisch mit einem Basisteil 46 verbunden, dass in Fig. 2 wie ein invertiertes U aussieht und zwei Schenkel 48, 50 und eine Basis 52 aufweist, welche diese Schenkel verbindet. Es können aber auch nur ein oder zwei Beinchen sein.2 to 4, the contact element 44 can have three legs 34, 36, 38 on its upper side in FIG. 2 and two legs 40, 42 on its lower side. All legs are electrically and mechanically connected to a base part 46, which looks like an inverted U in FIG. 2 and has two legs 48, 50 and a base 52 which connects these legs. But it can also be just one or two legs.
Zwischen den Schenkeln 48, 50 ist eine Federzunge 54 herausgestanzt, die an ihrem in Fig. 2 oberen Ende einstückig mit der Basis 52 ausgebildet ist. Die Federzunge 54 hat an ihrem in Fig. 3 linken Teil einen Abschnitt 56, an dem sie stark ansteigt und der in einen langsam abfallenden Abschnitt 58 übergeht, welcher zu einer Kontaktstelle 60 führt und von dort bei 62 langsam wieder ansteigt, so dass sich in Fig. 3 rechts eine Einführöffnung 64 bildet, in die ein strichpunktiert angedeutetes Blechteil 66 eingeführt werden kann, z. B. zur elektrischen Verbindung mit einem (nicht dargestellten) Motor, der von der Leiterplatte 20 aus gesteuert werden soll, oder zur Verbindung mit einem Netzteil oder mit einem beliebigen Gerät.A spring tongue 54 is punched out between the legs 48, 50 and is formed in one piece with the base 52 at its upper end in FIG. 2. The spring tongue 54 has on its left part in FIG. 3 a section 56 at which it rises sharply and which merges into a slowly falling section 58, which leads to a contact point 60 and from there slowly rises again at 62, so that in Fig. 3 forms an insertion opening on the right, into which a dash-dotted sheet metal part 66 can be inserted, z. B. for electrical connection to a (not shown) motor, which is to be controlled from the circuit board 20, or for connection to a power supply or to any device.
Das Basisteil 46 hat links und rechts je eine hoch gebogenen Wange 70 bzw. 72. Die Wange 70 ist am Schenkel 48 ausgebildet, die Wange 72 am Schenkel 50. Diese Wangen 70, 72 dienen als seitliche Führungsglieder für das Blechteil 66 bei dessen Montage.The base part 46 has left and right cheek 70 and 72, respectively. The cheek 70 is formed on the leg 48, the cheek 72 on the leg 50. These cheeks 70, 72 serve as lateral guide members for the sheet metal part 66 during its assembly.
MontageAssembly
Vor dem Einpressen des Kontaktelements 44 wird die Leiterplatte 20 an den erforderlichen Stellen mit Lötpaste bedruckt. Anschließend wird das Kontaktelement 44 in die Leiterplatte 20 eingepresst, wobei ein Teil der Lötpaste in Ausnehmungen 49 des Kontaktelements 44 gelangt und in diesen Ausnehmungen gespeichert wird.Before the contact element 44 is pressed in, the printed circuit board 20 is printed with solder paste at the required points. Subsequently, the contact element 44 is pressed into the printed circuit board 20, a portion of the solder paste reaching recesses 49 in the contact element 44 and being stored in these recesses.
Nach dem Einpressen werden die elektronischen Bauteile (SMD-Bauteile) in der üblichen Weise auf die zuvor aufgedruckte Lötpaste bestückt, und nachdem dies geschehen ist, wird die Leiterplatte durch einen Reflow-Ofen transportiert, wo die Lötung aller Bauteile stattfindet.After pressing in, the electronic components (SMD components) are placed in the usual way on the previously printed solder paste, and after this has been done, the circuit board is transported through a reflow oven, where the soldering of all components takes place.
Bei der Erfindung ist also nur ein einziger Zwischenschritt notwendig, nämlich das Einpressen des Kontaktelements 44. Alle anderen Prozesse müssen auch für die SMD- Bauteile durchgeführt werden, d. h. für die Montage des Kontaktelements 44 entstehen nur ganz geringe Mehrkosten.In the invention, therefore, only a single intermediate step is necessary, namely the pressing in of the contact element 44. All other processes must also be carried out for the SMD components, i. H. only very small additional costs arise for the assembly of the contact element 44.
Bei Fig. 1 ist darauf hinzuweisen, dass die Leiterbahn 22 an die Form des Kontaktelements 44 angepasst ist, wie sich das aus einem Vergleich der Fig. 1 und 2 direkt ergibt. Damit wird eine großflächige Verlötung erreicht. Um zu verhindern, dass beim Einpressen des Kontaktelements 44 die zuvor aufgebrachte Lötpaste komplett seitlich weggepresst wird, sind im Basisteil 46 durchgehende Ausnehmungen 49 vorgesehen, in welche bei diesem Einpressvorgang die Lötpaste teilweise gepresst wird, so dass beim Löten im Reflow-Ofen genügend Lötpaste zur Verfügung steht, um eine ordnungsgemäße Lötverbindung zu erhalten. Diese Ausnehmungen 49 dienen also als Reservoir für die Lötpaste.In FIG. 1, it should be pointed out that the conductor track 22 is adapted to the shape of the contact element 44, as can be seen directly from a comparison of FIGS. 1 and 2. Large-area soldering is thus achieved. In order to prevent the previously applied solder paste from being pressed completely to the side when the contact element 44 is pressed in, continuous recesses 49 are provided in the base part 46, into which the solder paste is partially pressed during this press-in process, so that sufficient solder paste to be used in the reflow oven Is available to get a proper solder joint. These recesses 49 thus serve as a reservoir for the solder paste.
Das Kontaktelement 44 wird, nachdem seine Beinchen 34 bis 42 in die Bohrungen 24 bis 32 der Leiterplatte 20 eingepresst wurden, im Reflow-Ofen in der üblichen Weise verlötet. Dabei fließt Lötzinn 74 in die Öffnungen 24 bis 32 und fließt durch Kapillarwirkung auch unter das Basisteil 46, wodurch dieses mit der Leiterbahn 22 großflächig verlötet wird. Dadurch wird eine zusätzliche mechanische Verbindung mit der Leiterplatte 20 hergestellt. Ebenso wird die Verbindungsanordnung 44 mit der Leiterbahn 22 elektrisch sicher verbunden.After its pins 34 to 42 have been pressed into the bores 24 to 32 of the printed circuit board 20, the contact element 44 is soldered in the reflow oven in the usual manner. In this case, solder 74 flows into the openings 24 to 32 and also flows under the base part 46 by capillary action, as a result of which this is soldered to the conductor track 22 over a large area. This creates an additional mechanical connection to the circuit board 20. Likewise, the connection arrangement 44 is electrically securely connected to the conductor track 22.
Das Blechteil 66 für den elektrischen Anschluss kann z. B. eine Breite von 0,8 cm haben. Bevorzugt hat es eine Ausnehmung, in die bei der Montage eine an der Federzunge 54 vorgesehene Warze oder dgl. einrastet, um eine sichere mechanische Verrastung zwischen Federzunge 54 und Blechteil 66 zu ermöglichen, was auch bei der Montage nützlich ist.The sheet metal part 66 for the electrical connection can, for. B. have a width of 0.8 cm. It preferably has a recess into which a wart or the like provided on the spring tongue 54 snaps into place in order to enable secure mechanical locking between the spring tongue 54 and the sheet metal part 66, which is also useful during assembly.
Nach dem Einschieben wird das Blechteil 66 an zwei seitlichen Bereichen, z.B. an den Stellen 76, 78, durch Schweißen mittels eines Lasers berührungslos fest geschweißt (sog. Laserpunkten). Dies ermöglicht eine Herstellung der Schweißverbindung an einer bereits bestückten Leiterplatte 20, ohne dass hierbei deren elektrische Bauelemente durch Fremdspannungen beschädigt oder zerstört werden können. Durch das Schweißen erhält man eine materialschlüssige Verbindung vom Kontaktelement 44 zum Blechteil 66, also eine sehr sichere und zuverlässige elektrische und zugleich mechanische Verbindung.After insertion, the sheet metal part 66 is attached to two lateral areas, e.g. at points 76, 78, non-contact welded by welding using a laser (so-called laser spots). This enables the welded connection to be produced on a printed circuit board 20 that has already been fitted, without the electrical components thereof being damaged or destroyed by external voltages. The welding results in a material connection from the contact element 44 to the sheet metal part 66, that is to say a very safe and reliable electrical and at the same time mechanical connection.
Fig. 5 zeigt eine Variante zu Fig. 3. Gleiche oder gleich wirkende Teile wie in Fig. 3 werden deshalb mit denselben Bezugszeichen bezeichnet.FIG. 5 shows a variant of FIG. 3. Parts which are the same or have the same effect as in FIG. 3 are therefore designated with the same reference symbols.
Nachteilig bei Fig. 3 kann sein, dass bei der Montage des Kontaktelements 44 ein Spalt zwischen diesem und der Leiterplatte 20 entsteht, welcher die Ausbildung einer sicheren Lötverbindung behindern könnte. Der Grund ist der, dass die Beinchen 34 bis 42 im rechten Winkel nach unten abgebogen sind, wobei unvermeidlich ein Biegeradius entsteht, welcher beim Einpressen den beschriebenen Spalt verursachen kann.A disadvantage of FIG. 3 may be that a gap is formed between the contact element 44 and the printed circuit board 20 during assembly, which gap could hinder the formation of a secure soldered connection. The reason is that the legs 34 to 42 are in the right Angles are bent downwards, whereby inevitably a bending radius arises which can cause the gap described when pressed in.
Die Variante nach Fig. 5 ermöglicht eine satte Auflage des Kontaktelements 44 auf der Leiterplatte 20. Bei dieser Variante werden die Beinchen zuerst hochgebogen und dann um 180° umgebogen. Dies ist am Beispiel der Beinchen 34' und 40' dargestellt. Das Beinchen 34' ist an der Stelle 57 in Richtung nach oben umgebogen, macht dann bei 59 eine Biegung um 180°, wobei der Radius dieser Biegung ggf. sehr klein gewählt werden kann, und geht von dort bei 61 senkrecht nach unten. Dieselbe Formgebung, aber spiegelbildlich findet sich beim Beinchen 40'.The variant according to FIG. 5 enables the contact element 44 to rest on the printed circuit board 20. In this variant, the legs are first bent up and then bent through 180 °. This is illustrated using the example of the legs 34 'and 40'. The leg 34 'is bent upwards at the point 57, then makes a bend by 180 ° at 59, the radius of this bend possibly being chosen to be very small, and from there it goes vertically downward at 61. The same shape, but mirror image, is found in the leg 40 '.
Durch diese Gestaltung kann das Basisteil 46 (Schenkel 48, 50 und Basis 52) satt auf der Leiterplatte aufliegen, so dass sich im Reflow-Ofen eine ausgezeichnete Lötverbindung ergibt, weil das Lot den gesamten Zwischenraum zwischen dem Kontaktelement 44 und der Leiterbahn 22 sicher ausfüllt. Hierbei sind die Ausnehmungen 49, welche bei Fig. 2 beschrieben wurden, sehr vorteilhaft und werden deshalb in gleicher Weise bei der Variante gemäß Fig. 5 verwendet.This design allows the base part 46 (legs 48, 50 and base 52) to lie snugly on the circuit board, so that there is an excellent solder connection in the reflow oven, because the solder reliably fills the entire space between the contact element 44 and the conductor track 22 , Here, the recesses 49, which were described in FIG. 2, are very advantageous and are therefore used in the same way in the variant according to FIG. 5.
Fig. 6 zeigt etwa im Maßstab 10:1 eine raumbildliche Darstellung eines Kontaktelements 80, das ähnlich aufgebaut ist wie das Kontaktelement 44 der Fig. 1 bis 5, aber nur vier Beinchen hat. Es hat ein Basisteil 82 mit zwei Längsschenkeln 84, 86, die auf einer Seite durch eine Basis 87 verbunden sind. Vom Schenkel 84 sind zwei Beinchen 88, 90 abgebogen und vom Schenkel 86 zwei Beinchen 92, 94.FIG. 6 shows a spatial representation of a contact element 80, approximately on a scale of 10: 1, which is constructed similarly to the contact element 44 of FIGS. 1 to 5, but has only four legs. It has a base part 82 with two longitudinal legs 84, 86 which are connected on one side by a base 87. Two legs 88, 90 are bent from leg 84 and two legs 92, 94 from leg 86.
Zwischen den Schenkeln 84, 86 ist eine federnde Kontaktzunge 96 herausgestanzt und in der dargestellten Weise geformt, um das Einführen eines elektrischen Leiters, z. B. eines flachen Metallteils, zu ermöglichen und um dieses flache Metallteil in der eingeführten Stellung sicher festzuhalten.Between the legs 84, 86, a resilient contact tongue 96 is punched out and shaped in the manner shown in order to insert an electrical conductor, for. B. a flat metal part, and to hold this flat metal part securely in the inserted position.
Fig. 7 zeigt die Befestigung eines als externer elektrischer Leiter dienenden Blechstreifens 66 am Kontaktelement 80. Letzteres ist auf einer Leiterplatte 20 in der zuvor beschriebenen Weise befestigt, wobei die Leiterbahn 22 (vgl. Fig. 1) hier zur Vereinfachung nicht dargestellt ist.FIG. 7 shows the fastening of a sheet metal strip 66 serving as an external electrical conductor to the contact element 80. The latter is fastened on a printed circuit board 20 in the manner described above, the conductor track 22 (cf. FIG. 1) not being shown here for simplification.
Wie man sieht, ist das Kontaktelement 80 mit seinen vier Beinchen 88, 90, 92, 94 in entsprechenden Ausnehmungen der Leiterplatte festgelötet. Das Blechteil 66 ist zwischen das Basisteil 82 und die federnde Zunge 96 eingeschoben. Letztere hat auf ihrer dem Blechteil 66 zugewandten Seite eine Warze 97, deren hohle Oberseite in Fig. 7 sichtbar ist. Das Blechteil 66 hat eine entsprechende (nicht dargestellte) Ausnehmung, und wenn es richtig eingeführt wird, rastet die Warze 97 in dieser Ausnehmung ein und hält dadurch das Blechteil 66 unverlierbar fest.As can be seen, the contact element 80 with its four legs 88, 90, 92, 94 is in corresponding recesses of the circuit board soldered. The sheet metal part 66 is inserted between the base part 82 and the resilient tongue 96. The latter has a wart 97 on its side facing sheet metal part 66, the hollow upper side of which is visible in FIG. 7. The sheet metal part 66 has a corresponding recess (not shown), and if it is inserted correctly, the wart 97 engages in this recess and thereby holds the sheet metal part 66 captively.
Anschließend wird das Blechteil 66 in seinem in Fig. 7 mit 100 bezeichneten Bereich durch Laser-Punktschweißen mit dem Basisteil 82 verschweißt. Dasselbe geschieht bevorzugt auch auf der in Fig. 7 nicht sichtbaren, gegenüberliegenden Seite. Auf diese Weise erhält man eine äußerst zuverlässige elektrische und mechanische Verbindung, die problemlos automatisiert hergestellt werden kann.The sheet metal part 66 is then welded to the base part 82 by laser spot welding in its area designated 100 in FIG. 7. The same happens preferably on the opposite side, not visible in FIG. 7. In this way, an extremely reliable electrical and mechanical connection is obtained, which can be easily automated.
Die Befestigung auf einer Leiterplatte 20 erfolgt in der gleichen Weise, wie das bei Fig. 1 bis 5 für das erste Ausführungsbeispiel beschrieben wurde, d. h. mittels eines Presssitzes in Bohrungen der Leiterplatte, wie in Fig. 7 dargestellt, und zusätzlich durch entsprechende Lötverbindungen. Die Beinchen 88, 90, 92, 94 können zu diesem Zweck an ihren freien Enden eine etwas reduzierte Breite haben, um die Montage in den Löchern der Leiterplatte zu vereinfachen.The attachment to a circuit board 20 is carried out in the same manner as that described for the first embodiment in FIGS. 1 to 5, i. H. by means of a press fit in holes in the printed circuit board, as shown in FIG. 7, and additionally by means of corresponding soldered connections. For this purpose, the legs 88, 90, 92, 94 can have a slightly reduced width at their free ends in order to simplify assembly in the holes in the printed circuit board.
Die Verbindung von einer Leiterbahn der Leiterplatte zu einem externen elektrischen Leiter hat zwei Komponenten: a) Die Verbindung von der Leiterbahn zum Kontaktelement. b) Die Verbindung vom Kontaktelement zum externen Leiter.The connection from a conductor track of the circuit board to an external electrical conductor has two components: a) The connection from the conductor track to the contact element. b) The connection from the contact element to the external conductor.
Die Verbindungskomponente a) bezieht ihre Sicherheit durch die Kombination eines Einpressvorgangs, der vorwiegend eine mechanische, aber auch eine elektrische Verbindung bewirkt, mit einem Lötvorgang, bei dem die niederohmige elektrische Verbindung im Vordergrund steht, aber auch eine mechanische Verbindung erzeugt wird.The connection component a) obtains its security through the combination of a press-in process, which primarily brings about a mechanical but also an electrical connection, with a soldering process in which the low-resistance electrical connection is in the foreground, but also a mechanical connection is produced.
Die Verbindungskomponente b) bezieht ihre Sicherheit durch das Verschweißen des flachen Leiters mit dem Kontaktelement, wobei das Einrasten des Leiters, und die Federkraft an der Kontaktzunge, eine zusätzliche Redundanz bewirken und die Montage erleichtern.The connection component b) obtains its security by welding the flat conductor to the contact element, the snap-in of the conductor and the spring force on the contact tongue causing additional redundancy and facilitating assembly.
Durch die Erfindung erhält man eine elektrische Verbindung von großer Sicherheit, die es ermöglicht, die Leiterbahn einer Leiterplatte sicher und zuverlässig mit einem externen Bauteil zu verbinden, in welchem hohe Ströme fließen, z. B. mit einem Elektromotor. Diese sichere und zuverlässige Verbindung wird ermöglicht durch eine Einpressverbindung zwischen Leiterplatte und Kontaktelement sowie durch eine Lötverbindung mit der Leiterbahn 22, und durch die berührungslos hergestellten Schweißverbindungen 76, 78, wie sie bei Fig. 2 beschrieben wurden. Dabei ist die Montage äußerst einfach und kann problemlos automatisiert werden, was auch durch das Einrasten zwischen Blechteil 66 und Federzunge 54 erleichtert wird.The invention provides an electrical connection of great security that it enables the conductor track of a circuit board to be safely and reliably connected to an external component in which high currents flow, e.g. B. with an electric motor. This secure and reliable connection is made possible by a press-in connection between the printed circuit board and the contact element and by a soldered connection to the conductor track 22, and by the welded connections 76, 78 produced in a contactless manner, as described in FIG. 2. The assembly is extremely simple and can be automated without any problems, which is also facilitated by the snapping between the sheet metal part 66 and the spring tongue 54.
Naturgemäß sind im Rahmen der vorliegenden Erfindung vielfache Abwandlungen und Modifikationen möglich. Naturally, numerous modifications and modifications are possible within the scope of the present invention.
