Derartige elektrische Steckkontakte werden häufig in Anwendungsbereichen eingesetzt, in denen sie einer relativ hohen Vibrationsbelastung ausgesetzt sind, z. B. in Kraftfahrzeugen. Da das Verbindungsprinzip bei derartigen Steckkontakten auf einer Klemmwirkung zwischen dem Steckkontakt und dem Steckanschluß beruht, kann es je nach Stärke der Klemmkraft bzw. der dadurch hervorgerufenen Reibkraft zwischen dem Steckanschluß und dem Steckkontakt und der Stärke der Vibrationen zu einer Relativbewegung zwischen dem Steckanschluß und dem Steckkontakt kommen. Diese Relativbewegung führt zu einem unerwünschten Verschleiß und je nach Materialauswahl auch zu einer Korrosion von Steckkontakt und Steckanschluß infolge der Reibung. Such electrical plug contacts are often in Used in applications where they are a relative are exposed to high vibration load, z. B. in motor vehicles. Since the connection principle in such Plug contacts on a clamping action between the plug contact and the plug connection is based, it can depending on the strength of the clamping force or caused thereby Frictional force between the plug connection and the Plug contact and the strength of the vibrations to one Relative movement between the plug connection and the Plug contact come.

Diese Aufgabe wird durch die in dem Patentanspruch 1 angegebene Erfindung gelöst. Weiterbildungen
und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen
angegeben. This object is solved by the invention defined in
Mit der Bezeichnung Formänderungswiderstand sei im folgenden eine Materialeigenschaft gemeint, die sich im wesentlichen umgekehrt proportional zu der Elastizität des Materials verhält.With the term deformation resistance is in the following a material property meant in the essentially inversely proportional to the elasticity of the material behaves.
Durch die im wesentlichen L-förmige Ausgestaltung des Steckkontakts sowie die Unterbringung der gesamten Steckzone in diesem L-förmigen Bereich wird ein besonders kompakter Aufbau des Steckkontakts erreicht. Mit der Bezeichnung L-förmig sollen in diesem Zusammenhang neben einem exakten rechten Winkel zwischen den Schenkeln des L-förmigen Bereichs auch geringe Abweichungen von dem rechten Winkel erfaßt sein.Due to the substantially L-shaped configuration of Plug contact as well as the accommodation of the entire Plug zone in this L-shaped area will be a special compact design of the plug contact reached. With The designation L-shaped should in this context next to an exact right angle between the thighs the L-shaped area also slight deviations be detected from the right angle.
Der erfindungsgemäße Steckkontakt kann besonders vorteilhaft zum Anschluß elektromechanischer Komponenten, z. B. Drucksensoren oder Magnetventile, an eine Steuerelektronik eingesetzt werden. In einer bevorzugten Anwendung sind dann die elektromechanischen Komponenten zusammen mit der Steuerelektronik in einem elektronischen Steuergerät angeordnet. Durch die Verformbarkeit des Steckkontakts können auch bei der Fertigung und Montage des elektronischen Steuergeräts auftretende Toleranzen ausgeglichen werden.The plug contact according to the invention can be particularly advantageous for connection of electromechanical components, z. As pressure sensors or solenoid valves, to an electronic control system be used. In a preferred application are then the electromechanical components together with the control electronics in an electronic Control unit arranged. Due to the deformability of the plug contact can also be used during manufacturing and Assembly of the electronic control unit occurring tolerances be compensated.
In einer vorteilhaften Ausgestaltung der Erfindung ist die gesamte Steckzone in dem einen Schenkel des L-förmigen Bereichs angeordnet, während der andere Schenkel als ein aus der Mechanik her bekannter Biegebalken fungiert. In an advantageous embodiment of the invention the entire mating zone in the one leg of the L-shaped Area arranged while the other leg acts as a known from the mechanics ago bending beam.
Das Problem des Reibverschleisses bzw. der Reibkorrosion wird bei dem erfindungsgemaßen Steckkontakt durch die Verformbarkeit der Zwischenzone erreicht, die eine Bewegung der Steckzone gegenüber der Verbindungszone in Steckrichtung in gewissem Umfang erlaubt, wodurch kleinere Bewegungen des Steckanschlusses z. B. infolge von Vibrationen kompensiert werden. In vorteilhafter Weise ist dabei in der Zwischenzone wenigstens ein erster Formänderungsbereich mit einem im Vergleich zu den übrigen Bereichen der Zwischenzone geringeren Formänderungswiderstand vorgesehen. Hierdurch erfolgt die Formanderung an einer definierten Stelle nach Art eines Gelenks.The problem of fretting or fretting corrosion is in the inventive plug contact the ductility of the intermediate zone is reached, the one Movement of the insertion zone in relation to the connection zone in Plugging direction allowed to some extent, resulting in smaller Movements of the plug connection z. B. as a result of Vibrations are compensated. In an advantageous way is at least a first in the intermediate zone Deformation range with one compared to the rest Regions of the intermediate zone lower deformation resistance intended. As a result, the shape change takes place at a defined point in the manner of a joint.
Gemäß der Erfindung ist in der Zwischenzone ein zweiter Formänderungsbereich mit verringertem Formänderungswiderstand vorgesehen, derart, daß die bevorzugte Verformungsrichtung des ersten und des zweiten Formänderungsbereichs entlang von parallel liegenden räumlichen Achsen angeordnet sind. Dies hat gegenüber einem einzelnen Formänderungsbereich den Vorteil, daß eine Verschwenkung der Steckzone bei einer Bewegung derselben infolge von Vibrationen besser vermieden werden kann. Hierdurch können auch Relativbewegungen zwischen der Steckzone und dem Steckanschluß quer zur Steckrichtung besser vermieden werden. Außerdem können Reibkräfte zwischen der Steckzone und den Wandungen einer den Steckkontakt haltenden Aufnahmevorrichtung vermieden oder zumindest reduziert werden. According to the invention is in the intermediate zone a second deformation range provided with reduced strain resistance, such that the preferred direction of deformation of along the first and the second strain-changing regions arranged by parallel spatial axes are. This has opposite to a single strain range the advantage that a pivoting of the plug-in zone in a movement of the same due to vibrations can be better avoided. This can also be done Relative movements between the plug-in zone and the plug connection be better avoided across the direction of insertion. In addition, frictional forces between the plug zone and the walls of a plug-in contact holding device avoided or at least reduced become.
Gemäß einer weiteren vorteilhaften Weiterbildung ist der Steckkontakt im Bereich der Verbindungszone und/oder der Zwischenzone mehrfach abgewinkelt, vorzugsweise in einer S-Form bzw. einer Mäanderform. Hierdurch ist der Steckkontakt besonders kompakt und kleinbauend, was den Vorteil hat, daß der Steckkontakt auch in elektronischen Geräten mit geringem Platzangebot einsetzbar ist.According to a further advantageous embodiment the plug contact in the region of the connection zone and / or the intermediate zone angled several times, preferably in an S-shape or a meander shape. hereby is the plug contact particularly compact and physically small, which has the advantage that the plug contact also in electronic devices with limited space can be used.
In einer weiteren vorteilhaften Weiterbildung der Erfindung dient die Verbindungszone gleichzeitig auch zur mechanischen Befestigung des Steckkontakts, so daß für die mechanische Befestigung kein besonderer Bereich oder Teil des Steckkontakt vorgesehen werden muß. Hierdurch wird insbesondere auch die preisgünstige Herstellbarkeit und der kompakte Aufbau des Steckkontakts gefördert.In a further advantageous embodiment of the invention serves the connection zone at the same time also for mechanical attachment of the plug contact, so that for the mechanical attachment no special area or part of the plug contact must be provided. hereby in particular, the low-cost manufacturability and the compact design of the plug contact promoted.
Der erste und/oder der zweite Formänderungsbereich weisen, wie bereits erläutert, einen geringeren Formänderungswiderstand auf als die übrigen Bereiche der Zwischenzone. Dies kann beispielsweise dadurch erreicht werden, daß der bzw. die Formänderungsbereiche bei im wesentlichen gleichbleibendem Materialquerschnitt einer Erwärmung unterworfen werden und hierdurch eine höhere Elastizität erreichen. Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung wird der geringere Formänderungswiderstand durch eine Verringerung des Materialquerschnitts der Zwischenzone erreicht. Besonders vorteilhaft ist es hierbei, die Materialdicke zu verringern, da dies zu einer relativ starken Verringerung des Flächenträgheitsmoments bei einer im Vergleich hierzu geringen Verringerung des Materialquerschnitts führt, was den Vorteil hat, daß der elektrische Widerstand im Bereich der Formänderungsbereiche nicht unnötig erhöht wird.The first and / or the second deformation range have, as already explained, a lower deformation resistance on than the remaining areas of the intermediate zone. This can be achieved, for example be that the or the deformation ranges in the essentially constant material cross-section of a Be subjected to warming and thereby a higher Achieve elasticity. According to a further advantageous Embodiment of the invention is the lower deformation resistance by reducing the material cross section reached the intermediate zone. Especially it is advantageous here to reduce the material thickness, because this leads to a relatively large reduction the area moment of inertia at a comparison For this purpose, a small reduction in the material cross section leads, which has the advantage that the electrical resistance not unnecessary in the field of strain ranges is increased.
Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung weist die Steckzone wenigstens zwei Aufnahmezungen zur Aufnahme des Steckanschlusses auf, deren außenliegende Kontur sich bei nicht gestecktem Steckanschluß in Richtung zu der der Zwischenzone abgewandten Seite der Steckzone verjüngt. Hierdurch wird gegenüber bekannten Steckkontakten, deren außenliegende Konturen der Steckzone im wesentlichen parallel zueinander verlaufen, der Vorteil erzielt, daß bei gleichem Platzbedarf die Steckkraft bzw. die Klemmkraft, mit der die Aufnahmezungen den Steckanschluß aufnehmen, erhöht wird. Infolge dessen wird auch die Reibkraft erhöht, und es kann Reibverschleiß und Reibkorrosion noch besser vermieden werden.According to a further advantageous embodiment of Invention, the insertion zone has at least two receiving tongues for receiving the plug-in connection, whose external Contour when not plugged plug connection facing away from the intermediate zone Side of the plug zone tapers. This is opposite known plug contacts whose outer contours the plug-in zone are substantially parallel to each other, achieved the advantage that the same footprint the insertion force or the clamping force with which the Receptacles record the plug connection, increased becomes. As a result, the frictional force is increased, and it can be even better at fretting and fretting corrosion be avoided.
In einer vorteilhaften Weiterbildung der Erfindung verändert sich die Querschnittsfläche einer Aufnahmezunge wenigstens in einem Teilbereich linear, vorzugsweise in dem mittleren Bereich der Aufnahmezunge. Dies hat den Vorteil, daß die mechanischen Spannungen, die infolge der Aufweitung des Steckkontakts beim Einstecken des Steckanschlusses auftreten, sich gleichmäßig verteilen und somit keine unerwünschten Spannungsüberhöhungen entstehen. Außerdem wird der Materialbedarf und somit das Gewicht des Steckkontakts minimiert. Hierdurch weist der Steckkontakt eine hohe Lebensdauer und ein geringes Gewicht auf. Modified in an advantageous embodiment of the invention the cross-sectional area of a receiving tongue at least in a partial region linear, preferably in the middle area of the receiving tongue. This has the Advantage that the mechanical stresses due to the widening of the plug contact when inserting the Plug connection occur, distribute evenly and thus no unwanted voltage peaks arise. In addition, the material requirement and thus minimizes the weight of the plug contact. hereby the plug contact has a long life and a low weight.
Es ist vorteilhaft, die infolge der Federwirkung der Aufnahmezungen auf den Steckanschluß ausgeübte Reibkraft deutlich höher zu dimensionieren als die sich aufgrund des Formänderungswiderstands der Formänderungsbereiche ergebende Kraft zur Verformung der Zwischenzone, insbesondere etwa doppelt so hoch.It is advantageous that due to the spring action of Tongues on the plug connection exerted frictional force to dimension much higher than the ones themselves due to the deformation resistance of the strain ranges resulting force for deformation of the intermediate zone, especially about twice as high.
Gemäß einer weiteren vorteilhaften Weiterbildung weist die Verbindungszone des Steckkontakts einen Bondbereich auf, an dem mittels Bonden ein elektrisches Bauteil anschließbar ist. Hierdurch ist der erfindungsgemäße Steckkontakt ohne weiteres auch für eine Anwendung in der Dickdrahtbond-Verbindungstechnik einsetzbar. Der Steckkontakt ist vorzugsweise aus dem Material Kupfer-Beryllium oder Kupfer-Zinn gefertigt. Hierbei tritt in der Praxis das.Problem auf, daß dieses Material einer Oxidation unterliegt, was nachteilig für die Anwendung der Dickdrahtbond-Technik ist. Gemäß einer vorteilhaften Weiterbildung der Erfindung weist der Bondbereich zumindest teilweise eine Beschichtung aus Aluminium auf. Hierdurch kann der Steckkontakt besser in Verbindung mit der Dickdrahtbond-Technik eingesetzt werden, da eine Aluminium-Oxidschicht für das Bonden nicht nachteilig ist. Es ist auch vorteilhaft, den Bondbereich unmittelbar vor dem Bonden einer Laserreinigung zu unterziehen. In diesem Fall kann gegebenenfalls auch auf die Aluminium-Beschichtung verzichtet werden.According to a further advantageous embodiment the connection zone of the plug contact a bond area on, by means of bonding an electrical component can be connected is. As a result, the inventive Plug contact readily for an application in the Dickdrahtbond connection technology used. Of the Plug contact is preferably made of the material copper beryllium or copper-tin. This occurs in The practice das.Problem that this material a Oxidation is subject to what is detrimental to the application the thick wire bonding technique is. According to an advantageous Development of the invention, the bonding area at least partially a coating of aluminum on. This allows the plug in contact better be used with the Dickdrahtbond technique, as an aluminum oxide layer for bonding is not is disadvantageous. It is also beneficial to the bond area immediately before bonding a laser cleaning to undergo. In this case, if necessary, too to dispense with the aluminum coating.
In einer weiteren vorteilhaften Weiterbildung weist die Verbindungszone (4) in dem Bondbereich (12) eine galvanisch aufgebrachte bondbare Beschichtung auf. Hierfür wird vorzugsweise Nickel-Phosphor als Beschichtungsmaterial verwendet.In a further advantageous embodiment, the Connecting zone (4) in the bonding area (12) a galvanic applied bondable coating on. Therefor is preferably nickel-phosphorus as a coating material used.
Gemäß einer weiteren vorteilhaften Weiterbildung der Erfindung ist eine Aufnahmevorrichtung für den elektrischen Steckkontakt vorgesehen, die Haltemittel aufweist, welche zur Aufnahme der Verbindungszone des Steckkontakts geeignet sind, derart, daß die Verbindungszone unbeweglich gegenüber der Aufnahmevorrichtung gehalten wird. Hierdurch kann der Steckkontakt relativ einfach montiert werden und mittels Umspritzen der Aufnahmevorrichtung in dem mit dem Steckkontakt zu versehenen elektrischen Gerät befestigt werden. Hierbei behält die Steckzone ihre Beweglichkeit gegenüber der Verbindungszone, welche infolge der unbeweglichen Aufnahme in der Aufnahmevorrichtung unbeweglich gegenüber dem elektrischen Gerät angeordnet ist..According to a further advantageous embodiment of Invention is a receiving device for the electrical Plug contact provided, which has holding means, which for receiving the connection zone of Plug contacts are suitable, such that the connection zone immovable relative to the receiving device is held. As a result, the plug contact relative be easily mounted and by molding the receiving device in the provided with the plug contact electrical device to be attached. Retains this the mating zone their mobility compared to the Connection zone, which as a result of immovable absorption immovable in the cradle the electrical device is arranged ..
Der Fertigungsschritt des Umspritzens unterscheidet sich beispielsweise von dem Fertigungsschritt des Vergießens dadurch, daß eine Umspritzung immer zu einer starren Befestigung führt, während beim Vergießen auch elastische Befestigungen möglich sind, z.B. durch Verwendung einer permanent elastischen Vergußmasse.The manufacturing step of overmoulding makes a difference For example, from the manufacturing step of the casting in that an encapsulation always to a rigid attachment leads while casting as well elastic fixings are possible, e.g. by using a permanently elastic sealing compound.
Die Montage der Aufnahmevorrichtung durch Umspritzen wird einerseits durch Verwendung eines relativ harten bzw. unflexiblen Materials, vorzugsweise harter Kunststoff, für die Aufnahmevorrichtung unterstützt, andererseits durch die Verwendung einer das Innere der Aufnahmevorrichtung vor der Umspritzmasse schützende Labyrinthdichtung, welche einen direkten Zugang der Umspritzmasse zu dem Inneren der Aufnahmevorrichtung versperrt.The mounting of the receiving device by molding on the one hand, by using a relatively hard one or inflexible material, preferably hard plastic, supported for the recording device, on the other hand by using a the inside of the cradle Protective labyrinth seal before overmoulding which gives a direct access to Umspritzmasse locked to the interior of the recording device.
Gemäß einer bevorzugten Weiterbildung weist die Aufnahmevorrichtung Bewegungsbegrenzungsmittel auf, welche diese Bewegbarkeit der Steckzone und/oder der Zwischenzone gegenüber der Aufnahmevorrichtung begrenzen. Durch geeignete Dimensionierung der Bewegungsbegrenzungsmittel kann der zu erwartenden Vibrationsbelastung in geeigneter Weise Rechnung getragen werden, ohne daß beliebig große Bewegungen oder gar plastische Verformungen des Steckkontakts auftreten.According to a preferred embodiment, the receiving device Motion limiting means on which this mobility of the plug-in zone and / or the intermediate zone limit against the recording device. By appropriate dimensioning of the movement limiting means can the expected vibration load in a suitable Be taken into account, without any arbitrary large movements or even plastic deformations of the plug contact occur.
Gemäß einer vorteilhaften Weiterbildung der Erfindung besteht die Aufnahmevorrichtung aus zwei Teilen, wobei die Teilungsebene in einer Ausführungsform im wesentlichen senkrecht und in einer weiteren Ausführungsform im wesentlichen parallel zu der raumlichen Achse der bevorzugten Verformungsrichtung des ersten Formänderungsbereichs ist. Dies hat den Vorteil, daß der Steckkontakt einfach in eine Hälfte der Aufnahmevorrichtung eingelegt werden kann, sodann die zweite Hälfte formschlüssig darauf gesteckt wird, womit bereits die Montage des Steckkontakts in der Aufnahmevorrichtung beendet ist. Hierdurch wird somit eine besonders einfache Montage des Steckkontakts und der Aufnahmevorrichtung unterstützt, wobei dieser Arbeitsschritt auch vollautomatisch maschinell ausführbar ist.According to an advantageous embodiment of the invention consists of the recording device of two parts, wherein the dividing plane in one embodiment substantially perpendicular and in another embodiment in the substantially parallel to the spatial axis of the preferred Deformation direction of the first strain area is. This has the advantage that the plug contact simply in one half of the cradle can be inserted, then the second half form-fitting put on it, which already the assembly the plug contact in the receiving device finished is. As a result, a particularly simple Assembly of the plug contact and the receiving device supported, this step also fully automatic is machine executable.

In den Figuren werden gleiche Bezugszeichen für einander entsprechende Teile verwendet.In the figures, the same reference numerals for each other used corresponding parts.
Der in den Fig. 1 bis 3 dargestellte elektrische Steckkontakt (1) besteht geometrisch aus einem L-förmigen Bereich (2, 5, 6, 7), an den sich ein S-förmiger bzw. mäanderförmiger Bereich (4, 5, 6) anschließt. Der Steckkontakt (1) weist an seinem einen Ende eine vollständig in dem einen Schenkel des L-förmigen Bereichs angeordnete Steckzone (2) auf, die geeignet ist, einen ihr als Gegenstück zugeordneten Steckanschluß (3) aufzunehmen. An seinem anderen Ende weist der Steckkontakt (1) eine vollständig in dem S-förmigen Bereich angeordnete Verbindungszone (4) auf, die zur elektrischen Verbindung des Steckkontakts mit einem elektrischen Bauteil, z. B. einer elektrischen Leiterplatte, dient. In einer bevorzugten Ausgestaltung weist die Verbindungszone (4) ein Bondpad (12) auf, welches vorzugsweise mittels Dickdrahtbonden mit dem elektrischen Bauteil elektrisch verbunden wird. Das Bondpad (12) ist in einer bevorzugten Ausgestaltung der Erfindung einstückig mit dem Steckkontakt (1) ausgeführt.The illustrated in FIGS. 1 to 3 electrical plug contact (1) is geometrically composed of an L-shaped Area (2, 5, 6, 7), to which an S-shaped or meandering region (4, 5, 6) connects. Of the Plug contact (1) has at its one end a complete in the one leg of the L-shaped area arranged plug-in zone (2), which is suitable, a to record their mating connector (3) assigned as a counterpart. At its other end, the plug contact (1) a completely disposed in the S-shaped area Connection zone (4), which is for electrical connection the plug-in contact with an electrical component, z. As an electrical circuit board, is used. In a preferred embodiment, the connection zone (4) a bonding pad (12), which is preferably using thick wire bonding with the electrical component is electrically connected. The bondpad (12) is in one preferred embodiment of the invention in one piece executed with the plug contact (1).
Als Werkstoff für den Steckkontakt (1) kommt bevorzugt Kupfer-Beryllium oder auch Kupfer-Zinn in Betracht. Das Bondpad (12) ist vorzugsweise mit einer Beschichtung aus Aluminium versehen. Alternativ zu der Aluminium-Beschichtung oder auch zusätzlich dazu kann das Bondpad (12) einer Laserreinigung unterzogen werden.As a material for the plug contact (1) is preferred Copper beryllium or copper-tin into consideration. The Bondpad (12) is preferably coated made of aluminum. Alternative to the aluminum coating or in addition to this, the bondpad (12) to undergo a laser cleaning.
Zwischen der Steckzone (2) und der Verbindungszone (4) weist der Steckkontakt (1) eine den L-förmigen und den S-förmigen Bereich überlappende Zwischenzone (5) auf, die verformbar ist, um der Steckzone (2) eine gewisse Bewegbarkeit in Steckrichtung (21) zur Kompensation von Vibrationen zu erlauben. Die Zwischenzone (5) ist als längliches Teil ausgebildet und dient als Biegebalken. Um eine definierte Verformbarkeit zu erzielen, sind im Bereich der Zwischenzone (5) ein erster (6) und ein zweiter (7) Formänderungsbereich vorgesehen. Der erste Formänderungsbereich (6) ist gemäß Fig. 1 in dem waagerechten Schenkel des L-förmigen Bereichs und der zweite Formänderungsbereich (7) in dem senkrechten Schenkel des L-förmigen Bereichs angeordnet, d.h. die Zwischenzone (5) ist zwischen den Formänderungsbereichen (6, 7) im wesentlichen rechtwinklig abgewinkelt.Between the plug-in zone (2) and the connection zone (4) the plug contact (1) has an L-shaped and the S-shaped area overlapping intermediate zone (5), which is deformable to the plug zone (2) a certain Movability in plug-in direction (21) to compensate for To allow vibrations. The intermediate zone (5) is as elongated part formed and serves as a bending beam. In order to achieve a defined deformability, are in Area of the intermediate zone (5) a first (6) and a second (7) deformation range provided. The first Form change range (6) is shown in FIG. 1 in the horizontal Leg of the L-shaped area and the second Deformation area (7) in the vertical leg of the L-shaped area, i. the intermediate zone (5) is between the strain ranges (6, 7) angled substantially at right angles.
Hierbei sind die bevorzugten Verformungsrichtungen des ersten und des zweiten Formänderungsbereichs (6, 7) entlang von parallel liegenden räumlichen Achsen angeordnet, wie in der Fig. 2 durch die gestrichelten Linien (18, 19) angedeutet ist. Bezüglich der Fig. 1 liegen diese Achsen somit senkrecht zur Papierebene. Durch die Verwendung zweier Formänderungsbereiche (6, 7) in der zuvor beschriebenen Anordnung kann eine Verschwenkung der Steckzone (2) bei einer Bewegung derselben infolge von Vibrationen besser vermieden werden und ein Reibverschleiß somit wirkungsvoller unterdrückt werden.Here are the preferred deformation directions of the first and second deformation changing sections (6, 7) arranged along parallel spatial axes, as shown in Fig. 2 by the dashed lines (18, 19) is indicated. With respect to FIG. 1 lie these axes thus perpendicular to the paper plane. By the use of two deformation zones (6, 7) in The arrangement described above can pivot the plug-in zone (2) during a movement of the same due better avoided by vibrations and a Frictional wear thus be suppressed more effectively.
Die Formänderungsbereiche (6, 7) haben einen geringeren Formänderungswiderstand als die übrigen Bereiche der Zwischenzone (5), was in einer bevorzugten Ausgestaltung der Erfindung durch einen verringerten Materialquerschnitt im Vergleich zu den übrigen Bereichen der Zwischenzone (5) erzielt wird. In einer vorteilhaften Weiterbildung ist in den Formänderungsbereichen (6, 7) insbesondere eine geringere Materialdicke vorgesehen als in den übrigen Bereichen der Zwischenzone (5). Hierdurch kann bei relativ großem Materialquerschnitt in den Formänderungsbereichen (6, 7) ein im Verhältnis hierzu kleines Flächenträgheitsmoment erzielt werden, wodurch ein günstiger Kompromiß zwischen leichter Verformbarkeit der Formänderungsbereiche (6, 7) und dem elektrischen Widerstand, welcher zur Vermeidung unnötiger Verluste möglichst gering sein sollte, erzielt wird.The shape change regions (6, 7) have a smaller one Deformation resistance than the remaining areas of the Intermediate zone (5), which in a preferred embodiment the invention by a reduced material cross-section compared to the other areas of the Intermediate zone (5) is achieved. In an advantageous Continuing education is in the deformation areas (6, 7) in particular provided a smaller material thickness than in the remaining areas of the intermediate zone (5). As a result, with a relatively large material cross section in the shape change areas (6, 7) in a ratio small area moment of inertia can be achieved for this, whereby a favorable compromise between easy deformability the shape change areas (6, 7) and the electrical resistance, which helps to avoid unnecessary Losses should be as low as possible achieved becomes.
Die Formänderungsbereiche (6, 7) sind bevorzugt als Verjüngung des Materials der Zwischenzone (5) ausgebildet, z. B. durch Prägen. Hierbei wird in etwa eine Halbierung der Dicke und der Breite des Materials der Zwischenzone (5) vorgesehen. The shape change regions (6, 7) are preferred as Rejuvenation of the material of the intermediate zone (5) formed, z. B. by embossing. This is about a halving the thickness and the width of the material of the intermediate zone (5) provided.
Alternativ können die Formänderungsbereiche (6, 7) auch durch eine lokale Schwächung des Materials der Zwischenzone (5) bei gleichbleibendem Materialquerschnitt realisiert werden, z. B. durch Erwärmung. Auch eine Kombination dieser Methoden ist vorteilhaft.Alternatively, the shape changing portions (6, 7) may also by a local weakening of the material of the intermediate zone (5) with constant material cross section be realized, for. B. by heating. Also one Combining these methods is beneficial.
Die Verbindungszone (4) dient des weiteren zur mechanischen Befestigung des Steckkontakts in einer dafür vorgesehenen Aufnahmevorrichtung, wie anhand der Fig. 5 bis 8 im folgenden noch näher erläutert wird.The connection zone (4) further serves for the mechanical Fixing the plug contact in a designated Receiving device, as with reference to FIG. 5 to 8 will be explained in more detail below.
Die Steckzone (2) weist zwei Aufnahmezungen (8, 9) auf, die zur Aufnahme des Steckanschlusses (3) dienen. Beim Einstecken des Steckanschlusses (3) wird die Steckzone (2) unter Verformung der Aufnahmezungen (8, 9) aufgeweitet, so daß der Steckanschluß (3) durch die Federwirkung des Materials der Aufnahmezungen (8, 9) festgehalten wird. Infolge von Reibung ist die Steckzone (2) gegenüber dem Steckanschluß (3) auch bei in Steckrichtung (21) wirkenden Kräften unbeweglich, solange die durch.die Haftreibung verursachte Haltekraft nicht überwunden wird.The plug-in zone (2) has two receiving tongues (8, 9), which serve to receive the plug connection (3). At the Inserting the plug connection (3) becomes the plug-in zone (2) expanded under deformation of the receiving tongues (8, 9), so that the plug connection (3) by the spring action the material of the receiving tongues (8, 9) held becomes. Due to friction, the plug-in zone (2) opposite the plug connection (3) also in plug-in direction (21) forces immovable, as long as the not caused by stiction is overcome.
In einer vorteilhaften Ausgestaltung der Erfindung ist der Formänderungswiderstand wenigstens des ersten Formänderungsbereichs (6) derart dimensioniert, daß bei Vorhandensein einer in Steckrichtung (21) wirkenden Kraft sich die Steckzone (2) unter Verformung der Zwischenzone (5) bewegt, ohne daß hierbei die Reibkraft zwischen dem Steckanschluß (3) und der Steckzone (2) überwunden wird, so daß sich die Steckzone (2) nicht gegenüber dem Steckanschluß (3) bewegt. Hierfür ist die Reibkraft höher zu wählen als die sich aufgrund des Formänderungswiderstands der Formänderungsbereiche (6, 7) ergebende Kraft zur Verformung der Zwischenzone (5). Vorzugsweise ist die Reibkraft deutlich höher zu wählen, besonders vorteilhaft etwa doppelt so hoch wie die für die Verformung notwendige Kraft. Hierdurch kann in vorteilhafter Weise eine permanente Reibung zwischen dem Steckanschluß (3) und der Steckzone (2) vermieden werden, z. B. bei Auftreten von Vibrationsbelastungen. Durch das Vermeiden von Reibbewegungen wird die Lebensdauer der Steckverbindung erhöht, da kein Reibverschleiß und keine Reibkorrosion auftreten.In an advantageous embodiment of the invention the deformation resistance of at least the first deformation range (6) dimensioned such that at Presence of acting in the direction of insertion (21) Force the plug zone (2) under deformation of the intermediate zone (5) moves, without causing the frictional force between the plug connection (3) and the plug-in zone (2) is overcome, so that the plug-in zone (2) not relative to the plug connection (3) moves. For this is the Friction force to choose higher than that due to the Deformation resistance of the deformation change regions (6, 7) resulting force for deformation of the intermediate zone (5). Preferably, the frictional force is much higher to choose particularly advantageous about twice as high as the necessary force for the deformation. This can be done in advantageously a permanent friction between the plug connection (3) and the plug-in zone (2) avoided be, for. B. when vibration loads occur. By avoiding friction movements, the life becomes the connector increases because no fretting and no fretting corrosion occur.
Wie insbesondere aus der Fig. 3 erkennbar ist, verjüngt sich die außenliegende Kontur (22, 31) der Aufnahmezungen bei nicht gestecktem Steckanschluß (3) in Richtung zu der der Zwischenzone (5) abgewandten Seite, d. h. in der vorliegenden Darstellung entgegen der Steckrichtung (21). Bei gestecktem Steckanschluß (3), wie in der Fig. 4 dargestellt, verlaufen die außenliegenden Konturen (22, 31) im wesentlichen parallel zueinander, so daß bei kompakter Bauweise eine hohe Klemmkraft und infolgedessen auch eine hohe Reibkraft zum Festhalten des Steckanschlusses (3) erzeugt wird. Die Querschnittsfläche einer Aufnahmezunge (8, 9) verändert sich dabei wenigstens in einem Teilbereich (10, 11) der jeweiligen Aufnahmezunge (8, 9) im wesentlichen linear. Hierdurch kann eine gleichmäßige Verteilung der mechanischen Spannungen bei gestecktem Steckanschluß (3) erzielt werden. As can be seen in particular from FIG. 3, tapers the outer contour (22, 31) of the receiving tongues with not plugged plug connection (3) in direction to the side facing away from the intermediate zone (5), d. H. in the present representation against the direction of insertion (21). With inserted plug connection (3), as in the Fig. 4, the outer contours extend (22, 31) substantially parallel to each other, so that in a compact design, a high clamping force and consequently also a high frictional force for holding the Plug connection (3) is generated. The cross-sectional area a receiving tongue (8, 9) changes at least in a partial area (10, 11) of the respective Recording tongue (8, 9) substantially linear. hereby can be a uniform distribution of mechanical Voltages with inserted plug connection (3) achieved become.
In den Fig. 5 bis 8 ist die Aufnahmevorrichtung (13) zur Aufnahme des Steckkontakts (1) mit darin angeordnetem Steckkontakt dargestellt. Die Aufnahmevorrichtung besteht aus zwei Halbschalen (16, 17), welche eine Teilungsebene aufweisen, die im wesentlichen senkrecht zu der räumlichen Achse (19) der bevorzugten Verformungsrichtung des ersten Formänderungsbereichs (6) ist. Die Halbschalen weisen formschlüssig ineinandergreifende Justiermittel (25) auf, die eine exakte Montage und Justierung der beiden Halbschalen (16, 17) zueinander vereinfachen.FIGS. 5 to 8 show the receiving device (13). for receiving the plug-in contact (1) with arranged therein Plug contact shown. The cradle consists of two half-shells (16, 17), which have a dividing plane which are substantially perpendicular to the spatial axis (19) of the preferred direction of deformation of the first strain area (6). The Half shells have a form-fitting interlocking Adjustment means (25) on which an exact assembly and adjustment the two half-shells (16, 17) to each other simplify.
Aus der Fig. 5 ist ersichtlich, wie der Steckanschluß (1) in der einen Halbschale (16) der Aufnahmevorrichtung (13) angebracht ist. Die Verbindungszone (4) wird dabei formschlüssig von Haltemitteln (23, 24) aufgenommen und von diesen unbeweglich gegenüber der Aufnahmevorrichtung (13) gehalten. Die Steckzone (2) sowie die Zwischenzone (5) bzw. zumindest der größte Teil davon ist in begrenztem Umfang bewegbar gegenüber der Aufnahmevorrichtung (13), wobei die Bewegbarkeit der Zwischenzone (5) durch Bewegungsbegrenzungsmittel (14, 15) auf ein erwünschtes Maß begrenzt wird. Durch die Begrenzung der Bewegbarkeit soll beispielsweise eine plastische Verformung der Zwischenzone (5) vermieden werden.From Fig. 5 it can be seen how the plug connection (1) in the one half shell (16) of the receiving device (13) is attached. The connection zone (4) becomes while positively received by holding means (23, 24) and of these immovable against the cradle (13) held. The plug-in zone (2) and the Intermediate zone (5) or at least the largest part thereof is to a limited extent movable relative to the receiving device (13), with the mobility of the intermediate zone (5) by movement limiting means (14, 15) is limited to a desired level. By the limitation the mobility should, for example, a plastic Deformation of the intermediate zone (5) can be avoided.
Zur vollständigen Montage des Steckkontakts (1) in der Aufnahmevorrichtung (13) ist zunächst der Steckkontakt (1) in die eine Halbschale (16) einzulegen, wie in der Fig. 5 dargestellt, und sodann die zweite Halbschale (17) daraufzustecken. Sodann kann die auf diese Weise entstandene Einheit in einem elektronischen Gerät montiert werden, beispielsweise durch Umspritzen der Aufnahmevorrichtung (13) in dem elektronischen Gerät. Die vorzugsweise aus Kunststoff hergestellten Halbschalen (16, 17) dienen hierbei zur allseitigen Kraftabstützung des Steckkontakts (1). Der zuvor beschriebene Montagevorgang läuft vorzugsweise vollautomatisch mittels einer hierfür vorgesehenen Bestückungsmaschine ab.For complete installation of the plug contact (1) in the Recording device (13) is initially the plug contact (1) to insert in the one half shell (16), as in the Fig. 5 is shown, and then the second half-shell (17) on it. Then that can be done this way resulting unit mounted in an electronic device be, for example by encapsulation of the recording device (13) in the electronic device. The preferably half shells made of plastic (16, 17) serve here for all-around force support of the plug contact (1). The assembly process described above preferably runs fully automatically by means of a provided for this insertion machine.
Um ein Eindringen von Umspritzmasse in die Aufnahmevorrichtung (13) zu vermeiden, ist diese mit einer Labyrinthdichtung (28) versehen, die einen direkten Zugang der Umspritzmasse zum Inneren Aufnahmevorrichtung (13) versperrt. Die Labyrinthdichtung (28) ist vorzugsweise als ein an der Halbschale (16) angeordneter umlaufender Vorsprung ausgebildet, der im montierten Zustand der Aufnahmevorrichtung (13) den Rand der Halbschale (17) überlappt.To prevent ingress of Umspritzmasse in the receiving device (13) to avoid this is with a labyrinth seal (28) providing direct access the Umspritzmasse to the internal recording device (13) blocked. The labyrinth seal (28) is preferably as a peripheral to the half-shell (16) arranged Formed in the mounted state of the projection Receiving device (13) the edge of the half-shell (17) overlaps.
