Description

Die Erfindung betrifft eine Hochstrom-Kabelklemme für eine Leiterplattenanordnung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a high-current cable clamp for a circuit board arrangement according to the preamble of patent claim 1.

Für die Funktion von auf Leiterplatten angebrachten elektronischen Schaltungen muß deren Stromversorgung sichergestellt werden. Dies bedeutet, daß auf der Leiterplattenanordnung Anschlüsse vorzusehen sind, an die stromführende Leitungen oder Kabel angeschlossen werden können. Zur Informationsübertragung sind auch Signalanschlüsse vorzusehen, jedoch ist bei den Anschlüssen zur Stromversorgung zu beachten, daß über diese wesentlich größere Leistungen übertragen werden. Zumeist müssen die Kabel zur Stromversorgung der Leiterplatte von der Leiterplatte lösbar sein, um deren Montage zu erleichtern. Für solch eine lösbare Verbindung bedarf es mechanischer Steckverbindungen.For the functioning of electronic circuits mounted on printed circuit boards, their power supply must be ensured. This means that connections must be provided on the circuit board arrangement to which live lines or cables can be connected. Signal connections are also to be provided for information transmission, but it should be noted with the connections to the power supply that much larger powers are transmitted via them. In most cases, the cables for the power supply to the circuit board must be detachable from the circuit board in order to facilitate their assembly. Such a detachable connection requires mechanical plug connections.

Dazu besteht dieser Anschluß aus Vorrichtung von in zwei parallelen Reihen angeordneten elastischen Einpreßstiften, die über eine Einpreßplatte mit einer Aufnahme für Kabelschuhe bzw. Stifte für Steckhülsen verbunden ist. Jedoch weist auch diese Bauform eine große Bauhöhe auf und erfordert zusätzlich, daß das Stromversorgungskabel mit einer Hülse bzw. einem Schuh versehen wird.From the company script Ernipress

Power supply connections for bus systems "from 1992 there is also known a power supply connection which is suitable for power supply cables with plug sleeves or with cable lugs. For this purpose, this connection consists of a device of elastic press-in pins arranged in two parallel rows, which are connected via a press-in plate is connected to a receptacle for cable lugs or pins for receptacles. However, this design also has a large overall height and additionally requires that the power supply cable is provided with a sleeve or a shoe.

Die Aufgabe der Erfindung besteht in der Gestaltung einer Hochstrom-Kabelklemme für eine Leiterplattenanordnung, die die leistungsstarke Stromspeisung der Leiterplattenanordnung mit wenigen lösbaren Komponenten ermöglicht. Die Aufgabe wird durch die Hochstromkabelklemme nach dem Oberbegriff des Patentanspruchs 1 durch die Merkmale des kennzeichnenden Teils gelöst.The object of the invention is to design a high-current cable clamp for a circuit board arrangement, which enables the powerful current supply of the circuit board arrangement with a few detachable components. The object is achieved by the high-current cable clamp according to the preamble of claim 1 by the features of the characterizing part.

Eine Einpreßvorrichtung wird dazu mit einer Schraubklemme nichtlösbar und mit geringem Übergangswiederstand leitend verbunden. Die Schraubklemme weist dabei einen Klemmkörper mit einem von außen zugänglichen Hohlraum zur Aufnahme eines Hochstromkabels und einen einstellbaren Befestigungskörper zur Justierung des Hochstromkabels auf. Das Hochstromkabel kann damit ohne weitere Hilfsmittel in der Schraubklemme befestigt werden. Zudem erfordert eine solche Schraubklemme keine große Bauhöhe, so daß auch die Gesamtabmessung der Hochstromkabelklemme gering bleiben kann. Damit auch hohe Ströme über die Kabelklemme übertragen werden können, weist die Einpreßplatte mehrere zum Einpressen in die Leiterplattenanordnung geeignete Einpreßstifte auf. Die Zahl der Einpreßzonen wird dabei entsprechend dem maximal zu übertragenden Strom ausgewählt.For this purpose, a press-in device is non-releasably connected with a screw terminal and is conductively connected with a low transition resistance. The screw clamp has a clamp body with an externally accessible cavity for receiving a high-current cable and an adjustable fastening body for adjusting the high-current cable. The high-current cable can thus be fastened in the screw terminal without any additional aids. In addition, such a screw clamp does not require a large overall height, so that the overall dimension of the high-current cable clamp can also remain small. So that even high currents can be transmitted via the cable clamp, the press-in plate has a plurality of press-in pins suitable for being pressed into the circuit board arrangement. The number of press-in zones is selected according to the maximum current to be transmitted.

Vorteilhafterweise sind diese Einpreßstifte als im Vergleich zur Platte der Einpreßvorrichtung senkrecht abstehender Reihen von Einpreßstiften, insbesondere elastischen oder unelastischen Stiften, ausgebildet. Es kann ebenso vorgesehen sein, daß mehrere solcher Einpreßvorrichtungen mit der Schraubklemme verbunden sind. Zur Erzielung einer geringen Bauhöhe ist die Einpreßplatte als dünne Platte ausgeprägt.Advantageously, these press-in pins are designed as rows of press-in pins, in particular elastic or inelastic pins, which project vertically compared to the plate of the press-in device. It can also be provided that several such press-in devices are connected to the screw terminal. To achieve a low overall height, the press-fit plate is designed as a thin plate.

Die Befestigung und Kontaktierung der Hochstromkabelklemme mit der Leiterplattenanordnung kann dadurch bewirkt werden, daß der Querschnitt der Einpreßstifte so auf den Querschnitt der Löcher in der Leiterplattenanordnung abgestimmt ist, daß ein selbsthaltendes festes und kontaktsicheres Einpressen ermöglicht wird. Alternativ dazu kann der Querschnitt der Einpreßstifte so bemessen sein, daß nach dem Einsetzen auch ein Verlöten möglich ist.The attachment and contacting of the high-current cable clamp with the circuit board arrangement can be effected in that the cross section of the press-fit pins is matched to the cross section of the holes in the circuit board arrangement in such a way that a self-holding, firm and contact-safe pressing is made possible. Alternatively, the cross section of the press-in pins can be dimensioned such that soldering is also possible after insertion.

Nach einer weiteren vorteilhaften Ausgestaltung der Hochstromkabelklemme weist die Einpreßvorrichtung Noppen auf und wird über Punktschweißstellen mit dem Klemmkörper verbunden. Eine einfache und wirtschaftlich herstellbare Ausgestaltungsmöglichkeit der Schraubklemme besteht darin, den Befestigungskörper als Schraube und den Hohlraum des Klemmkörpers als Durchgangsbohrung mit eingelegtem Klemmblech auszuprägen. Die Bauhöhe kann zusätzlich dadurch beeinflußt werden, daß die Klemmschraube zur Justierung des Hochstromkabels senkrecht oder parallel zur Leiterplattenanordnung bzw. zur Platte der Einpreßvorrichtung wirkt.According to a further advantageous embodiment of the high-current cable clamp, the press-in device has knobs and is connected to the clamp body via spot welds. A simple and economically producible design option for the screw terminal consists in designing the fastening body as a screw and the cavity of the clamping body as a through hole with an inserted clamping plate. The overall height can also be influenced by the fact that the clamping screw for adjusting the high-current cable acts perpendicularly or parallel to the circuit board arrangement or to the plate of the press-in device.

Die erfindungsgemäße Hochstromkabelklemme soll im folgenden anhand von zeichnerischen Darstellungen näher erläutert werden.The high-current cable clamp according to the invention will be explained in more detail below with the aid of drawings.

Die Hochstromkabelklemme nach FIG 1 (Vorderansicht) und 2 (Seitenansicht) besteht aus einem quaderförmigen Klemmkörper 3, der mit einer Einpreßvorrichtung 7 durch mehrere Punktschweißstellen über Noppen in der Einpreßvorrichtung 7 verbunden ist. Die Einpreßvorrichtung 7 besteht beispielsweise aus einer Zinn-Bronze-Legierung, wie auch der Klemmkörper 3. Die Einpreßvorrichtung 7 weist zwei Reihen von beispielsweise je fünf Einpreßstiften auf, wobei die beiden Reihen parallel sind und senkrecht von der Platte der Einpreßvorrichtung 7 abstehen. Diese Form der Einpreßvorrichtung 7 kann leicht durch Stanzen und Biegen aus einem Blech hergestellt werden.The high-current cable clamp according to FIG. 1 (front view) and 2 (side view) consists of a cuboid-shaped clamping body 3, which is connected to a press-in device 7 by means of several spot welds via knobs in the press-in device 7. The press-in device 7 consists, for example, of a tin-bronze alloy, as does the clamping body 3. The press-in device 7 has two rows of, for example, five press-in pins, the two rows being parallel and projecting perpendicularly from the plate of the press-in device 7. This form of the press-in device 7 can easily be produced by stamping and bending from a sheet metal.

Die Einpreßstifte 8 sind in einem Raster angeordnet, das dem der Leiterplattenanordnung 1 entspricht. Die Einpreßstifte 8 sind in ihrem Querschnitt an die entsprechenden Löcher in der Leiterplattenanordnung 1 angepaßt. Die Einpreßstifte 8 können sowohl elastisch als auch unelastisch ausgeprägt sein, wodurch sich verschiedene Arten der Kontaktierung ergeben. Die DIN Norm 41611 gibt dafür verschiedene Formen einer Einpreßverbindung an. Zudem kann die Hochstromkabelklemme zusätzlich in der Leiterplattenanordnung 1 verlötet werden, wenn die Querschnitte von Einpreßstiften 8 und Löchern in der Leiterplattenanordnung 1 entsprechend ausgestaltet sind.The press-in pins 8 are arranged in a grid which corresponds to that of the printed circuit board arrangement 1. The cross-section of the press-in pins 8 is adapted to the corresponding holes in the circuit board arrangement 1. The press-in pins 8 can be both elastic and inelastic, which results in different types of contact. The DIN standard 41611 specifies various forms of a press-in connection. In addition, the high-current cable clamp can also be soldered in the circuit board arrangement 1 if the cross sections of press-in pins 8 and holes in the circuit board arrangement 1 are configured accordingly.

Der quadratische Klemmkörper 3 weist eine Durchgangsbohrung in der Achse der Reihe der Einpreßzonen auf, in die das Hochstromkabel 5 eingeführt werden kann. Zum Feststellen des Hochstromkabels 5 in diesen Hohlraum 4 ist eine Klemmschraube 6 vorgesehen. Diese Klemmschraube 6 wirkt jedoch auf das Hochstromkabel 5 nicht direkt, sondern über ein Klemmblech. Dieses Klemmblech ist jedoch für die Funktion der Hochstromkabelklemme nicht unbedingt erforderlich. Die Klemmschraube 6 kann in den Klemmkörper 3 eingeschraubt werden und übt so eine Druckkraft auf das Hochstromkabel 5 aus. In den FIG 1 und 3 bis 6 ist das Hochstromkabel 5 jedoch nicht dargestellt.The square clamping body 3 has a through hole in the axis of the row of press-fit zones into which the high-current cable 5 can be inserted. A clamping screw 6 is provided for fixing the high-current cable 5 in this cavity 4. However, this clamping screw 6 does not act on the high-current cable 5 directly, but via a clamping plate. However, this clamping plate is not absolutely necessary for the function of the high-current cable clamp. The clamping screw 6 can be screwed into the clamping body 3 and thus exerts a compressive force on the high-current cable 5. In Figures 1 and 3 to 6, the high-current cable 5 is not shown.

Zum Einschrauben der Klemmschraube 6 ist eine Gewindebohrung im Klemmkörper 3 eingebracht. Diese Gewindebohrung ist in FIG 1 senkrecht zur Leiterplattenanordnung 1, also in Richtung der Einpreßstifte 8 vorgesehen. Somit ergibt sich eine einfache Justierung des Hochstromkabels 5 über die Klemmschraube 6, jedoch eine im Vergleich zu der Hochstromkabelklemme von FIG 2 erhöhte Bauhöhe.For screwing in the clamping screw 6, a threaded hole is made in the clamping body 3. This threaded bore is provided in FIG. 1 perpendicular to the circuit board arrangement 1, that is to say in the direction of the press-in pins 8. This results in a simple adjustment of the high-current cable 5 via the clamping screw 6, but an increased overall height in comparison to the high-current cable clamp from FIG.

Die Kabelklemme nach FIG 3 und 4 unterscheidet sich von der nach FIG 1,2 darin, daß die Klemmschraube 6 parallel zur Leiterplattenanordnung 1 in den Klemmkörper 3 eingeschraubt wird. Hierdurch kann die Bauhöhe weiter reduziert werden.The cable clamp according to FIGS. 3 and 4 differs from that according to FIG. 1 2 in that the clamping screw 6 is screwed into the clamping body 3 parallel to the circuit board arrangement 1. This allows the overall height to be reduced further.

Da pro Einpreßstift 8 nur eine bestimmte Leistung übertragen werden kann, ist es mitunter erforderlich eine größere Anzahl von Einpreßstiften 8 vorzusehen. Dazu kann die Zahl der Einpreßstifte 8 pro Reihe der Einpreßvorrichtung 7 erhöht werden. In FIG 5,6 ist dies der Fall und es sind pro Reihe sieben Einpreßstifte 8 vorgesehen. Es besteht jedoch auch die Möglichkeit, mehrere Einpreßvorrichtungen 7 mit dem Klemmkörper 3 zu verbinden. Evtl. ist es dazu nötig, die Dimension des Klemmkörpers 3 im Vergleich zu den Varianten nach FIG 1,2 und Fig 3,4 zu erhöhen. Wird auch ein Hochstromkabel 5 mit größerem Querschnitt eingesetzt, ist es vorteilhaft auch mehrere Klemmschrauben 6 zur Befestigung des Hochstromkabels 5 im Klemmkörper 3 zu verwenden. Ebenso ist erweist es sich als nötig, die Zahl der Punktschweißstellen zu erhöhen.Since only a certain power can be transmitted per press-in pin 8, it is sometimes necessary to provide a larger number of press-in pins 8. For this purpose, the number of press-in pins 8 per row of press-in device 7 can be increased. This is the case in FIG. 5, 6 and seven press-in pins 8 are provided per row. However, there is also the possibility of connecting a plurality of press-in devices 7 to the clamping body 3. Possibly. it is necessary to increase the dimension of the clamping body 3 in comparison to the variants according to FIGS. 1,2 and 3,4. If a high-current cable 5 with a larger cross section is also used, it is also advantageous to use a plurality of clamping screws 6 for fastening the high-current cable 5 in the clamping body 3. It is also necessary to increase the number of spot welds.

Die erfindungsgemäße Hochstromkabelklemme kann auf einfache Weise an verschiedene Anforderungen der Leistungsübertragung auf einer Leiterplattenanordnung 1 angepaßt werden. Die Bauhöhe ist leicht anpaßbar, auch kann durch die Wahl der Anzahl der Einpreßstifte und ihre Anordnung eine flexible Anpassung an die zu übertragende Stromstärke und die Eigenart der Leiterplattenanordnung 1 erreicht werden.The high-current cable clamp according to the invention can be easily adapted to various requirements of power transmission on a circuit board arrangement 1. The overall height is easily adaptable, and by the choice of the number of press-in pins and their arrangement, flexible adaptation to the current intensity to be transmitted and the peculiarity of the printed circuit board arrangement 1 can be achieved.
