Die Erfindung betrifft ein Kontaktelement. Das Kontaktelement ist ausgebildet, einen Draht galvanisch zu kontaktieren. Das Kontaktelement ist bevorzugt einstückig aus elektrisch leitfähigem Blech gebildet. Das Kontaktelement weist auch wenigstens eine mit dem Blech verbundene Kontaktfeder auf, wobei die Kontaktfeder ausgebildet ist, den Draht beim Verbinden mit dem Kontaktelement kraftschlüssig und/oder formschlüssig festzuhalten und elektrisch zu kontaktieren. Das Kontaktelement ist bevorzugt ausgebildet, mit einer Leiterplatte mittels Löten verbunden zu werden.The invention relates to a contact element. The contact element is designed to galvanically contact a wire. The contact element is preferably formed in one piece from electrically conductive sheet metal. The contact element also has at least one contact spring connected to the metal sheet, wherein the contact spring is designed to positively hold the wire when connecting to the contact element and / or positively and to contact it electrically. The contact element is preferably designed to be connected to a printed circuit board by means of soldering.
Bei aus dem Stand der Technik bekannten Leiterplatten, welche mit elektronischen Bauelementen bestückt werden, stellt sich bei Leiterplatten mit SMD-Bauelementen (SMD = Surface Mounted Device) das Problem, dass Bauelemente, beispielsweise Kondensatoren, welche wenigstens einen Anschlussdraht aufweisen, in einem zweiten Lötprozess mit der Leiterplatte verbunden werden müssen, wohingegen die SMD-Bauelemente in einem ersten Lötschritt mit der Leiterplatte verlötet werden.In known from the prior art printed circuit boards, which are equipped with electronic components, arises in printed circuit boards with SMD components (SMD = Surface Mounted Device) the problem that components, such as capacitors, which have at least one connecting wire, in a second soldering must be connected to the circuit board, whereas the SMD components are soldered in a first soldering step with the circuit board.
Aus der
Offenbarung der ErfindungDisclosure of the invention
Bevorzugt weist das Kontaktelement eine Kontaktfläche auf, welche ausgebildet ist, den Draht auf einem Längsabschnitt des Drahtes zu kontaktieren. Die Kontaktfeder weist bevorzugt im Bereich eines zum Kontaktieren des Drahtes ausgebildete Anpressfläche auf und ist bevorzugt angeordnet und ausgebildet, den Draht mit der Anpressfläche federnd elektrisch oder zusätzlich wärmeleitend zu kontaktieren und gegen die Kontaktfläche zu drücken, wobei die Kontaktfläche größer ist als die Anpressfläche. Preferably, the contact element has a contact surface which is designed to contact the wire on a longitudinal section of the wire. The contact spring preferably has in the region of a contact surface formed for contacting the wire and is preferably arranged and configured to contact the wire with the contact surface resiliently electrically or additionally thermally conductive and to press against the contact surface, wherein the contact surface is greater than the contact surface.
Durch die größere Kontaktfläche kann der Längsabschnitt des Drahtes, insbesondere im Bereich eines Drahtendes das Kontaktelement mit einer großen Fläche entlang des Längsabschnittes galvanisch kontaktieren.As a result of the larger contact surface, the longitudinal section of the wire, in particular in the region of a wire end, can make galvanic contact with the contact element with a large area along the longitudinal section.
In einer bevorzugten Ausführungsform ist das Kontaktelement durch einen Winkel mit zwei Schenkeln gebildet. Bevorzugt weist ein Schenkel des Winkels eine Öffnung zum Einführen des Drahtes in das Kontaktelement, insbesondere in eine durch den Schenkel mit der Kontaktfläche und die Kontaktfeder gebildete Klemme, auf. Mittels des Winkels kann der Draht, insbesondere ein Draht eines elektronischen Bauelements besonders aufwandsgünstig mit der Leiterplatte verbunden werden. Dazu kann der Winkel zusammen mit weiteren SMD-Bauelementen (SMD = Surface-Mounted-Device) mit der Leiterplatte in einem Lötschritt verbunden werden. In einem anschließenden Montageschritt kann das Bauelement mit dem Draht mit dem Winkel durch Stecken verbunden werden.In a preferred embodiment, the contact element is formed by an angle with two legs. A leg of the angle preferably has an opening for inserting the wire into the contact element, in particular into a clamp formed by the leg with the contact surface and the contact spring. By means of the angle, the wire, in particular a wire of an electronic component, can be connected to the printed circuit board in a particularly cost-effective manner. For this purpose, the angle together with other SMD components (SMD = surface-mounted device) can be connected to the circuit board in a soldering step. In a subsequent assembly step, the device can be connected to the wire with the angle by plugging.
In einer bevorzugten Ausführungsform weist der zu dem Schenkel mit der Öffnung abgewinkelte Schenkel auf der dem Schenkel mit der Öffnung zugewandten Seite die Kontaktfläche auf. Die zur Kontaktfläche gegenüberliegende Seite des Schenkels weist bevorzugt eine Lötfläche zum Verbinden mit der Leiterplatte auf. So kann das Kontaktelement vorteilhaft mit einem Schenkel mit der Leiterplatte verbunden werden, wobei derselbe Schenkel den Draht des Bauelements galvanisch kontaktiert. Dadurch ist weiter vorteilhaft ein geringer ohmscher Übergangswiderstand zwischen dem Draht und der Lötfläche gegeben, welche lediglich durch eine Dicke des Bleches des Schenkels mit der Kontaktfläche und der Lötfläche bestimmt ist. In a preferred embodiment, the leg which is angled away from the leg with the opening has the contact surface on the side facing the leg with the opening. The opposite side of the leg to the contact surface preferably has a soldering surface for connection to the printed circuit board. Thus, the contact element can be advantageously connected to a leg with the circuit board, wherein the same leg contacted the wire of the device galvanically. As a result, a low ohmic contact resistance between the wire and the soldering surface is advantageously provided, which is determined only by a thickness of the metal sheet of the leg with the contact surface and the soldering surface.
Bevorzugt ist die Lötfläche mit der Kontaktfläche und der Anpressfläche elektrisch verbunden. Dazu ist der Schenkel mit der Kontaktfläche und der Lötfläche bevorzugt aus elektrisch leitfähigem Material, insbesondere aus elektrisch leitfähigem Blech, insbesondere Kupferblech oder Stahlblech gebildet. Das Kontaktelement weist auf der Lötfläche bevorzugt eine Lotschicht, insbesondere eine Zinnschicht auf. Dadurch wird ein Verlöten in einem späteren Lötprozess mit einer Leiterbahn der Leiterplatte erleichtert.Preferably, the soldering surface is electrically connected to the contact surface and the contact surface. For this purpose, the leg with the contact surface and the soldering surface is preferably formed from electrically conductive material, in particular from electrically conductive sheet metal, in particular copper sheet or sheet steel. The contact element preferably has a solder layer, in particular a tin layer, on the soldering surface. This facilitates soldering in a subsequent soldering process with a conductor track of the printed circuit board.
In einer bevorzugten Ausführungsform weist eine Seite des Schenkels mit der Öffnung eine Lötfläche zum Verbinden mit der Leiterplatte auf. Die Seite ist bevorzugt diejenige, durch welche der Draht in die Öffnung zum Verbinden mit dem Kontaktelement eingeführt werden kann.In a preferred embodiment, one side of the leg having the opening has a soldering surface for connection to the printed circuit board. The side is preferably the one through which the wire can be inserted into the opening for connection to the contact element.
Dadurch kann das elektronische Bauelement mit dem wenigstens einen Draht vorteilhaft durch die Leiterplatte hindurch mit dem Kontaktelement verbunden werden, welches auf einer gegenüberliegenden Seite der Leiterplatte mit der Leiterplatte verlötet ist. Die Leiterplatte weist bevorzugt im Bereich der Öffnung des Kontaktelements einen Durchbruch zum Durchführen des Drahtes auf. So kann eine Leiterplatte vorteilhaft von zwei Seiten mit Bauelementen bestückt werden. Die Leiterplatte weist dann auf beiden Seiten wenigstens ein Kontaktelement auf, welches zum galvanischen Verbinden mit dem elektronischen Bauelement ausgebildet ist.As a result, the electronic component with the at least one wire can advantageously be connected through the printed circuit board to the contact element, which is soldered to the printed circuit board on an opposite side of the printed circuit board. The printed circuit board preferably has an opening for passing the wire in the region of the opening of the contact element. Thus, a circuit board can be advantageously equipped from two sides with components. The circuit board then points on both sides at least one contact element, which is designed for galvanic connection to the electronic component.
Bevorzugt bildet die Kontaktfläche eine Rinne. Die Rinne kann beispielsweise mittels Prägen in dem Schenkel mit der Kontaktfläche ausgeformt sein. Durch die Rinne kann der Draht vorteilhaft auf einer größeren Fläche des Längsabschnitts des Drahtes, bevorzugt an zwei längsgestreckten Flächenabschnitten, galvanisch kontaktiert werden. Bevorzugt weist die Rinne einen V-förmigen Querschnitt auf. Dadurch kann der Draht an zwei Längsabschnitten mit dem Schenkel galvanisch kontaktiert werden. In anderen Ausführungsformen weist die Rinne einen U-förmigen, halbkreisförmigen, halbellipsenförmigen oder reckteckförmigen Querschnitt auf. Preferably, the contact surface forms a groove. The groove can be formed, for example, by embossing in the leg with the contact surface. The wire advantageously allows the wire to be galvanically contacted on a larger area of the longitudinal section of the wire, preferably on two elongated surface sections. Preferably, the channel has a V-shaped cross-section. As a result, the wire can be galvanically contacted at two longitudinal sections with the leg. In other embodiments, the channel has a U-shaped, semicircular, semi-elliptical or rectangular cross-section.
In einer bevorzugten Ausführungsform ist die Kontaktfeder durch einen Blechabschnitt gebildet, der an den Schenkeln mit der Öffnung anschließt und sich mit einem Ende der Kontaktfläche entgegenstreckt. Dadurch kann die Kontaktfeder besonders aufwandsgünstig bereitgestellt werden, da diese bevorzugt an den Schenkel angeformt ist. Weiter bevorzugt ist die Kontaktfeder von dem Schenkel mit der Öffnung abgewinkelt.In a preferred embodiment, the contact spring is formed by a sheet metal section, which connects to the legs with the opening and extends with one end of the contact surface. As a result, the contact spring can be provided in a particularly cost-effective manner, since it is preferably molded onto the leg. More preferably, the contact spring is angled from the leg with the opening.
Das Kontaktelement kann zusätzlich zu der bereits beschriebenen Kontaktfeder eine weitere Kontaktfeder aufweisen. Dazu kann das Blech des Schenkels mit der Öffnung beispielsweise im Bereich eines Endes in seiner Längserstreckung zweigeteilt sein. Mittels eines Teils, welcher sich abgewinkelt der Kontaktfläche entgegenstreckt, kann der Draht federnd kontaktiert und festgehalten werden. Mittels des zweiten Teils, welcher sich ebenfalls abgewinkelt der Kontaktfläche entgegenstreckt, kann der Draht entlang seines Längsabschnittes an einem weiteren Berührungsort federnd festgehalten und galvanisch kontaktiert werden.The contact element may have a further contact spring in addition to the already described contact spring. For this purpose, the sheet metal of the leg with the opening, for example in the region of one end in its longitudinal extent be divided into two. By means of a part which angled extends the contact surface, the wire can be resiliently contacted and held. By means of the second part, which likewise extends at an angle to the contact surface, the wire can be resiliently held along its longitudinal section at a further contact location and can be galvanically contacted.
Die Kontaktfeder ist beispielsweise ausgebildet, in einem Zustand des Kontaktelements, bei dem kein Draht durch das Kontaktelement kontaktiert wird, die Kontaktfläche federnd zu berühren. In einer anderen Ausführungsform berührt die Kontaktfeder die Kontaktfläche nicht und ist mit einem vorbestimmten Abstand von der Kontaktfläche beanstandet. Der Abstand ist bevorzugt kleiner als ein Drahtdurchmesser eines mit dem Kontaktelement zu verbindenden Drahtes. The contact spring is formed, for example, in a state of the contact element in which no wire is contacted by the contact element to contact the contact surface resiliently. In another embodiment, the contact spring does not contact the contact surface and is jammed at a predetermined distance from the contact surface. The distance is preferably smaller than a wire diameter of a wire to be connected to the contact element.
In einer bevorzugten Ausführungsform weist die Kontaktfeder wenigstens zwei Endabschnitte auf, welche jeweils ausgebildet sind, den Draht an zueinander verschiedenen Berührungsorten insbesondere Einschneidens zu kontaktieren und federnd gegen die Kontaktfläche zu drücken. Mittels der so ausgebildeten Kontaktfeder, welche beispielsweise wie vorab beschrieben durch die zwei Endabschnitte gebildet sein kann, kann der Draht vorteilhaft mittels zwei Kontaktfedern doppelt sicher mit dem Kontaktelement verbunden sein und so sicher galvanisch kontaktiert werden.In a preferred embodiment, the contact spring has at least two end portions, which are each designed to contact the wire at mutually different contact locations, in particular incision, and to press resiliently against the contact surface. By means of the thus formed contact spring, which may be formed, for example, as described above by the two end portions, the wire can advantageously be connected by means of two contact springs twice securely connected to the contact element and so safely contacted galvanically.
Die Erfindung betrifft auch eine Leiterplatte mit einem Kontaktelement gemäß der vorbeschriebenen Art. Die Leiterplatte weist wenigstens eine elektrisch leitfähige Schicht, insbesondere eine Kupferschicht auf. Die Leiterplatte weist auch ein Trägermaterial auf, beispielsweise faserverstärktes Epoxidharz. Die Leiterplatte ist bevorzugt auf zwei Seiten mit einer elektrisch leitfähigen Schicht kaschiert und weist wenigstens auf einer Seite wenigstens ein Kontaktelement der vorbeschriebenen Art auf, dessen Lötfläche mittels Löten mit der Leiterplatte verbunden ist. Die Leiterplatte weist weiter bevorzugt auf beiden Seiten wenigstens ein Kontaktelement der vorbeschriebenen Art auf.The invention also relates to a printed circuit board with a contact element according to the above-described type. The printed circuit board has at least one electrically conductive layer, in particular a copper layer. The printed circuit board also has a carrier material, for example fiber-reinforced epoxy resin. The circuit board is preferably laminated on two sides with an electrically conductive layer and has at least on one side at least one contact element of the type described above, the soldering surface is connected by means of soldering to the circuit board. The circuit board further preferably has on both sides at least one contact element of the type described above.
