Abstract

The connector includes a series of grooves (15). These run down from a peak (21), commencing from a convex cylindrical surface (22), changing to a steeply-angled planar surface (23), eventually reaching the flat surface of the base plate (6). The planar surface (23) is so constructed and disposed, that when the claw arm (12) is rolled up, its tip is self-locking into or against this surface (23). (Note: mechanical contact is made against the far side of the groove as viewed in the illustration) This resists unrolling of the claw.

Die Erfindung betrifft eine Criiπpkralle eines elektrischen Kontaktelements aus einem Blechstanzteil zum Crimpen eines elektrischen Flachbandflachleiters nach de» Oberbegriff des Anspruchs 1.The invention relates to a crimping claw of an electrical contact element made from a stamped sheet metal part for crimping an electrical flat ribbon conductor according to the preamble of claim 1.
Flachbandflachleiter, auch Flachleiter, Flachkabel. Folienleiter oder Bandkabel genannt, weisen in der Regel mehrere im Abstand voneinander parallel nebeneinander angeordnete, relativ dünne bandförmige metallische Leiterbahnen auf, die in einem Isolier- εtoffiπaterialband voneinander elektrisch isoliert eingebettet sind. Dabei können die Leiterbahnen oberflächlich oder im Innern des Isolierstoffmaterialbandes angeordnet sein.Flat ribbon flat conductors, also flat conductors, flat cables. Foil conductors or ribbon cables generally have a plurality of relatively thin ribbon-shaped metallic conductor tracks arranged parallel to one another at a distance from one another and embedded in an insulating material tape in an electrically insulated manner. The conductor tracks can be arranged on the surface or in the interior of the insulating material strip.
Die Erfindung befaßt sich mit der elektrischen ontaktierung der Leiterbahnen derartiger Flachbandflachleiter.The invention is concerned with the electrical contacting of the conductor tracks of such flat ribbon flat conductors.
Aus der DE 25 00 556 C2 igt eine Crimpkralle eines elektrischen Kontaktelements bekannt, deren Krallenarme das Isolierstoffmate- rial durchdringen, die Längskanten des Flachleiters umgreifen und gegen eine Querrillen aufweisende Langswölbung des Bodens der Criiηpkralle eingerollt sind, wobei sie den ebenfalls eingerollten Längskantenbereich umgeben. Dabei ist in einem Bogenbereich eine flächige Kontaktierung zwischen der bogenförmigen Innenfläche des jeweiligen eingerollten Krallenarms und der Unterseite des eingerollten, vom Isolierstoff beim Crimpen befreiten Längskantenbereich bewirkt. Zudem durchdringen die Spitzenbereiche der Krallenarme den Flachleiter und gewährleisten jeweils eine zweite Kontaktstelle {DE 25 00 556 C2, Fig. 3). Diese bekannte Crimpkralle erfordert hohe Crimpkräfte insbeson- dere für das Durchdringen des Flachleiters. Außerdem können Rückstellkräfte, die nach dem Einrollen der Crimpkralle auftreten, ein Zurückfedern der Krallenarme bewirken, mit dem Ergebnis, daß die Durchdringungskontaktierung und/oder die flächige Kontaktierung beeinträchtigt werden. Eine gasdichte Kontaktierung ist auf diese Weise dauerhaft nicht erreichbar.A crimping claw of an electrical contact element is known from DE 25 00 556 C2, the claw arms of which penetrate the insulating material, embrace the longitudinal edges of the flat conductor and are rolled up against a longitudinal curvature of the bottom of the crimping claw, which surrounds the likewise rolled up longitudinal edge area. In this case, a flat contact is made in an arc region between the arc-shaped inner surface of the respective rolled-in claw arm and the underside of the rolled-in longitudinal edge region, which is freed from the insulating material during crimping. In addition, the tip areas of the claw arms penetrate the flat conductor and each ensure a second contact point (DE 25 00 556 C2, FIG. 3). This known crimping claw requires high crimping forces in particular for the penetration of the flat conductor. In addition, restoring forces which occur after the crimping claw has rolled in can cause the claw arms to spring back, with the result that the penetration contact and / or the flat contact are impaired. In this way, gas-tight contacting cannot be permanently achieved.
Aus der US-FS 5,137,468 Fig. 5 bis 7 ist eine gleiche Crimpkralle bekannt, die aber derart eingerollt ist, daß die bogenförmige Außenfläche der eingerollten Spitzenbereiche der Krallenarme die Oberseite des Längskantenbereichs des Flachleiters kontaktieren, wobei die Spitzen der Krallenarme beim Crimpen Isolierstoffmaterial vom Flachleiter abgeschabt haben. Dabei wird der Flachbandleiter mit dem konvexen Bogen des jeweiligen Krallenarms gegen den auf dem konvexen Bogen der Bodenwölbung im Querrillenbereich abgestützten Flachleiter gedrückt. Aus dieser Konfiguration der Crimpkralle resultieren punktförmige Kontaktstellen, die - nach der Lehre der Druckschrift - im Massenproduktiσnsprozeß nicht ausreichend sicher ausgeführt werden können.A similar crimping claw is known from US-FS 5,137,468, FIGS. 5 to 7, but is rolled up in such a way that the arcuate outer surface of the rolled-up tip regions of the claw arms contact the upper side of the longitudinal edge region of the flat conductor, the tips of the claw arms during crimping insulating material from the flat conductor scraped off. The flat ribbon conductor with the convex arch of the respective claw arm is pressed against the flat conductor supported on the convex arch of the floor arch in the transverse groove area. This configuration of the crimping claw results in point-like contact points which - according to the teaching of the publication - cannot be carried out with sufficient certainty in the mass production process.
Demgemäß befaßt sich der Gegenstand der US-PS 5,137,468 mit einer Verbesserung der ebenfalls bekannten flächigen Kontaktierung der Oberseite des Längskantenbereichs des Flachleiters. Gemäß Fig. 3 der Druckschrift ist jeweils die konvexe Außenfläche des Endbereichs der eingerollten Krallenarme einem konkaven Bogenbereich gleichen Radius einer sich nur bis zur Quermitte der Längswölbung erstreckenden Querrille gegenüberliegend angeordnet, wobei dazwischen der Flachleiter zur elektrischen Kontaktierung eingespannt ist. Nachteilig bei dieser Kontaktierung ist ebenfalls, daß die Krallenaπve nach dem Crimpvorgang auf einer Kreisbahn ungehindert zurückfedern können und sich dabei die Kontaktstelle öffnet, wodurch die Kontaktierung mit dem Flachleiter gestört oder sogar aufgehoben sein kann. In der Druckschrift ist zwar erwähnt, daß die Bögen nicht konzentrisch sein müssen und daß der Bogen einer Rille aus mehreren unterschiedlichen Radien bestehen kann, warum dies sein kann, wird nicht angegeben. Die Spitze der Crimpkralle muß punktgenau den Übergangsbereich in dem konkaven Bogenbereich treffen. Bereits kleinste Toleranzen, die es im Fertigungsprozeß immer gibt, können die Kontaktierung komplett verhindern.Accordingly, the subject of US Pat. No. 5,137,468 is concerned with an improvement in the likewise known surface contacting of the upper side of the longitudinal edge region of the flat conductor. According to FIG. 3 of the document, the convex outer surface of the end region of the rolled-up claw arms is arranged opposite a concave arc region of the same radius of a transverse groove which only extends to the transverse center of the longitudinal curvature, the flat conductor for electrical contact being clamped in between. A disadvantage of this contact is also that the Krallenaπve can spring back unhindered on a circular path after the crimping process and the contact point opens, whereby the contact with the flat conductor can be disturbed or even canceled. It is mentioned in the publication that the arcs do not have to be concentric and that the arc of a groove can consist of several different radii, and why this can be so is not stated. The tip of the crimping claw must be precise Meet the transition area in the concave arc area. Even the smallest tolerances, which are always present in the manufacturing process, can completely prevent contacting.

Ein elektrisches Kontaktelement aus einem Blechstanzteil weist in der Regel einen Kon aktbereich 2 und einen Crimpbereich 3 auf, die über einen Übergangsbereich 4 miteinander einteilig in Verbindung stehen (Fig. 6} . Die Raumfαrm des Kontaktbereichs 4 kann beliebig sein, weshalb sie im Rahmen der Beschreibung der vorliegenden Erfindung unberücksichtigt bleibt.An electrical contact element made from a stamped sheet metal part generally has a contact area 2 and a crimp area 3, which are connected to one another in one piece via a transition area 4 (FIG. 6}. The spatial shape of the contact area 4 can be arbitrary, which is why it is part of the Description of the present invention is not considered.
Der Crimpbereich 3 weist eine Crimpkralle 5 auf, die zum Crimpen eines Flachbandflachleiters 27 ausgebildet ist.The crimping area 3 has a crimping claw 5, which is designed for crimping a flat ribbon conductor 27.
Die Crirtpkralle 5 besteht aus einer im wesentlichen langgestreckten ebenen Bodenplatte 6 mit den Längskanten 7 und S, einer freien Endkante 9 sowie einer Oberfläche 10 und einer Unterfläche 11.The crimp claw 5 consists of an essentially elongated flat base plate 6 with the longitudinal edges 7 and S, a free end edge 9 and a surface 10 and a lower surface 11.
An die Längskanten 7, S sind etwa rechtwinklig abgewinkelte, über die Oberfläche 10 überstehende Krallenarme 12 angebunden. Die Krallenarme 12 an beiden Längskanten 7, 8 sind in Querrichtung der Bodenplatte 6 nicht sich gegenüberliegend, sondern diagonal versetzt angeordnet.Claw arms 12, which are angled approximately at right angles and protrude above surface 10, are connected to longitudinal edges 7, S. The claw arms 12 on the two longitudinal edges 7, 8 are not arranged opposite one another in the transverse direction of the base plate 6, but are offset diagonally.
Die Crimpkralle nach Fig. 6 weist z.B. an der einen Längskante 7 zwei Krallenarme 12 und an der anderen Längskante 8 drei Krallenarme 12 jeweils in einer Längsreihe auf. In jeder Reihe ist jeweils zwischen zwei Krallenarmen 12 eine Lücke 13 vorgesehen. Einer Lücke 13 gegenüberliegend ist an der anderen Längskante jeweils ein Krallenarm 14 angebunden. Die Anzahl der Krallenarme 12 und der Lücken 13 ist wählbar; im einfachsten Fall reichen zwei sich diagonal gegenüberliegende Krallenarme 12 aus. Die Krallenarme 12 haben eine Zungenform und laufen in einem abgerundeten Spitzenbereich 16 aus, der zweck äßigerweise keilförmig dünner geprägt ist mit einer zum freien Ende hin abgeschrägten ebenen Außenfläche. Aus der etwa dreieckförmigen Zungenform der Krallenarme 12 resultieren in etwa V-förmige bis U-förmige Luken 13, so daß die Lücken 13 in etwa die Negativform der Krallenarme 12 aufweisen.6 has, for example, on one longitudinal edge 7 two claw arms 12 and on the other longitudinal edge 8 three claw arms 12 each in a longitudinal row. A gap 13 is provided in each row between two claw arms 12. Opposite a gap 13, a claw arm 14 is connected to the other longitudinal edge. The number of claw arms 12 and the gaps 13 can be selected; in the simplest case, two diagonally opposite claw arms 12 are sufficient. The claw arms 12 have a tongue shape and terminate in a rounded tip region 16, which is expediently embossed wedge-shaped with a flat outer surface that is beveled towards the free end. The approximately triangular tongue shape of the claw arms 12 results in approximately V-shaped to U-shaped hatches 13, so that the gaps 13 have approximately the negative shape of the claw arms 12.
In der Quermitte der Bodenplatte 6 ist zwischen den Krallenarmen 12 ein sich in Längsrichtung der Bodenplatte 6 erstreckender, über die Oberfläche 10 überstehender Wulst 14 angeordnet, der z.B. von der Unterseite der Bodenplatte 6 nach oben durchgedrückt sein kann. Im Wulst 14 sind Querrillen 15 eingefσrmt, die jeweils einem Krallenarm 12 in Querrichtung der Bodenplatte 6 gegenüberliegend positioniert sind. Die Breite der Rillen 15 entspricht etwa der Breite des Spitzenbereichs 16 eines Krallenarms 12.Arranged in the transverse center of the base plate 6 between the claw arms 12 is a bead 14 which extends in the longitudinal direction of the base plate 6 and projects beyond the surface 10 and which, e.g. can be pushed upwards from the underside of the base plate 6. In the bead 14 transverse grooves 15 are formed, each of which is positioned opposite a claw arm 12 in the transverse direction of the base plate 6. The width of the grooves 15 corresponds approximately to the width of the tip region 16 of a claw arm 12.
Wesentlich ist die Raumform des Wulstes 14 und der Rillen 15 in Querrichtung der Bodenplatte 6.The spatial shape of the bead 14 and the grooves 15 in the transverse direction of the base plate 6 is essential.
Nach einer ersten Ausführungsform der Erfindung (Fig. 1, 2) geht der Wulstzenit 18 in Querrichtung über eine konvexe Zylinder- bogenfläche 17 in eine ebene, steil zur Bodenplatte 6 abfallende erste schräge Fläche 1$ über, an die sich eine zweite ebene, schräge, etwas flacher zur Bodenplatte 6 abfallende, in letztere übergehende Fläche 20 anschließt.According to a first embodiment of the invention (FIGS. 1, 2), the bead zenite 18 transversely transitions over a convex cylindrical arch surface 17 into a flat, sloping first surface 1 $ that slopes steeply towards the base plate 6, to which a second flat, inclined surface is formed , slightly flat to the bottom plate 6, merging into the latter surface 20 connects.
Der Winkel der Fläche 19 zur ebenen Oberfläche 10 der Bodenplatte 6 liegt vorzugsweise zwischen 50 und 70°. Zudem liegt der Winkel zwischen der Fläche 20 und der Oberfläche 10 der Bodenplatte 6 vorzugsweise zwischen 20 und 40°.The angle of the surface 19 to the flat surface 10 of the base plate 6 is preferably between 50 and 70 °. The angle also lies between the surface 20 and the surface 10 of the base plate 6, preferably between 20 and 40 °.
Um die Rillentiefe nach unten versetzt verläuft der Rillenboden in Querrichtung zur Bodenplatte 6 wie die Wulstober läche. Mithin weist der Rillenboden einen Rillenzenit 21 auf, der in Querrichtung über eine konvexe Zylinderbogenflache 22 in eine schräge, ebene, steil zur Bodenplatte 6 abfallende Fläche 23 übergeht, an die sich eine weitere ebene, schräge, etwas flacher zur Bodenplatte 6 abfallende, in letztere übergehende Fläche 24 anschließt.To the groove depth offset down the groove bottom runs in the transverse direction to the base plate 6 as the bead surface. Thus, the groove bottom has a groove zit 21, which transversely merges via a convex cylindrical arch surface 22 into an inclined, flat surface 23 that slopes steeply towards the base plate 6, to which another flat, inclined surface, which slopes somewhat flatly, into the latter merging surface 24 connects.
Der Winkel der Fläche 23 zur ebenen Oberfläche 10 der Bodenplatte 6 liegt zwischen 50 und 70°. Außerdem liegt der Winkel zwischen der Fläche 24 und der Oberfläche 10 der Bodenplatte 6 zwischen 20 und 40°.The angle of the surface 23 to the flat surface 10 of the base plate 6 is between 50 and 70 °. In addition, the angle between the surface 24 and the surface 10 of the base plate 6 is between 20 and 40 °.
Nach Fig. 1 und 2 erstrecken sich die Rillen 15 quer über den gesamten Wulst 14. Notwendig ist aber die erfindungsgemäße Rillenausgestaltung nur auf der Seite, auf der der Rille 15 ein Krallenarm 12 gegenüberliegend angeordnet ist, weil dieser Krallenann lediglich mit dieser Rillenhälfte zusammenwirkt.1 and 2, the grooves 15 extend across the entire bead 14. However, the groove configuration according to the invention is only necessary on the side on which the groove 15 has a claw arm 12 arranged opposite, because this claw only interacts with this groove half.
Die Erfindung sieht vor, daß der jeweilige Krallenarm 12 derart eingerollt wird, daß er mit seiner Außenfläche gegen den Wulst 14 und die Rille 15 auf seiner Längsseite neben der Längsmitte 26 gedrückt wird, wobei dazwischen ein Flachbandflachleiter 27 angeordnet ist. Der Rollradius des Krallenarms 12 ist dabei auf den Winkel der Schräge 19 und/oder 23 zur Bodenplatte 6 derart abgestimmt, daß beim unvermeidbaren Rückfedern des Krallenarros 12 nach dem Crimpen und/oder bei einer Zugwirkung auf den Flachbandflachleiter eine Selbsthemmung des Krallenfederarms bewirkt wird. Diese Selbsthemmving verdeutlichen die Figuren 7 und 8. Der Spitsenbereich 16 durchdringt das Basismaterial 29 des Flachbandflachleiters 27, wird vom Obersteϊt-pel des Crimpwerkzeugs (nicht dargestellt) erfaßt und derart verformt, daß der Spitzenbereich 16 vorzugsweise im Bereich der konvexen Zylinderbogen- fläche 17 oder auf den schrägen Flächen 19, 20 auf die Kupferfreifläche 28 des Flachbandflachleiters 27 trifft. Dabei wird der Flachbandflachleiter 27 zwischen der Außenfläche des Krallenarms 12 und der Fläche 19 (Fig. 7) und/oder der Fläche 20 (Fig. 8) geklemmt. Die Kontaktierung erfolgt über die Außenfläche des Krallenarms 12 und die Oberseite der Kupferfreifläche 28 des Flachband lachleiters 27 „The invention provides that the respective claw arm 12 is rolled in such a way that its outer surface is pressed against the bead 14 and the groove 15 on its long side next to the longitudinal center 26, a flat ribbon conductor 27 being arranged in between. The rolling radius of the claw arm 12 is matched to the angle of the bevel 19 and / or 23 to the base plate 6 such that self-locking of the claw spring arm is brought about in the event of inevitable springback of the claws arm 12 after crimping and / or in the event of a tensile effect on the flat ribbon conductor. This self-locking is illustrated in FIGS. 7 and 8. The tip area 16 penetrates the base material 29 of the flat ribbon conductor 27, is gripped by the uppermost part of the crimping tool (not shown) and is deformed in such a way that the tip area 16 preferably in the area of the convex cylindrical arc surface 17 or on the inclined surfaces 19, 20 meets the copper free surface 28 of the flat ribbon conductor 27. The flat ribbon conductor 27 is clamped between the outer surface of the claw arm 12 and the surface 19 (FIG. 7) and / or the surface 20 (FIG. 8). The contact is made via the outer surface of the claw arm 12 and the top of the copper free surface 28 of the flat ribbon conductor 27 "
Eine weitere Aus ührungsform der erfindungsgemäßen Crimpkralle (Fig. 3, 4) sieht vor, daß der Zenit 18 des Wulsts 14 mit dem Zenit 21 der Rillen 15 zusammenfällt. Aus dieser Raumform resultiert eine längere Auslaufschräge 24 der Rillen 15 i Vergleich zur Auslaufschräge 20 des Wulsts 14, Diese Ausführungsform stellt eine fertigungstechnische Vereinfachung dar.Another embodiment of the crimping claw according to the invention (FIGS. 3, 4) provides that the zenith 18 of the bead 14 coincides with the zenith 21 of the grooves 15. This spatial shape results in a longer run-out slope 24 of the grooves 15 i compared to the run-out slope 20 of the bead 14. This embodiment represents a simplification in terms of production technology.
Die Ausführungsform der Erfindung nach Fig. 5 sieht vor, daß die beidseitigen Außenkanten der Rillen 15 schneidenförmig ausgebildet sind und über die Wulεtoberflache überstehen, woraus Schneiden 25 resultieren. Hierdurch wird eine zusätzliche Kontaktierung des Leiters 30 von der Unterseite ermöglicht. Die Schneiden 25 durchdringen dabei das Basismaterial 29 und kontaktieren den Leiter 30 des Flachbandflachleiters 27-The embodiment of the invention according to FIG. 5 provides that the outer edges of the grooves 15 on both sides have a cutting shape and protrude beyond the bead surface, resulting in cutting edges 25. This enables additional contacting of the conductor 30 from the underside. The cutting edges 25 penetrate the base material 29 and contact the conductor 30 of the flat ribbon conductor 27.
Die Ausführungsform der Erfindung nach Fig. 9 sieht vor, daß der Flachbandflachleiter 27 keine Kupferfreifläche 28 besitzt. Der Spitzenbereich 16 des Krallenarms 12 durchdringt die Deckschicht 31 des Flachbandflachleiters 27 und schabt diese ab und kontaktiert mit seiner Außenfläche auf dem Leiter 30»The embodiment of the invention according to FIG. 9 provides that the flat ribbon conductor 27 has no copper open area 28. The tip region 16 of the claw arm 12 penetrates the cover layer 31 of the flat ribbon conductor 27 and scrapes it off and makes contact with its outer surface on the conductor 30.
Die Erfindung schafft somit eine Selbsthemiming der Krallenarme im kontaktierenden Bereich nach dem Crimpen und definierte Kontaktzonen. Außerdem ergibt sich eine gasdichte Kontaktsone, wobei Flachbandflachleiter jeglicher Art kontaktiert werden können*» Es kann eine sichere Kontaktierung im Langzeitbetrieb gewährleistet werden. Die Kontaktierung erfolgt mit dem Auslaufbogen der Crimpkralle, der sich auf einer Schrägen abstützt, die vom Flachleiter gebildet wird, der auf der schrägen Fläche des Wulstes und der Rille aufliegt. Die Kontaktierung erfolgt über der Schrägfläche 19/23 des Wulsts und/oder der Rille, wobei insbesondere die Kontaktierung auch auf der Auslaufschräge der beiden Elemente erfolgen kann.The invention thus creates self-locking of the claw arms in the contacting area after crimping and defined contact zones. In addition, there is a gas-tight contact zone, with flat ribbon conductors of any kind being able to be contacted * »Secure contacting in long-term operation can be guaranteed. The contact is made with the outlet arch of the crimping claw, which is supported on a slope, which is formed by the flat conductor, which is on the inclined surface of the Bead and the groove rests. The contacting takes place over the inclined surface 19/23 of the bead and / or the groove, wherein in particular the contacting can also take place on the run-out slope of the two elements.
Zum Erreichen einer optimalen Stelbsthemmung der Krallenarme können die schrägen Flächen 19, 23 und/oder 20, 24 leicht konvex in Richtung auf den Flachbandflachleiter gewölbt sein. To achieve optimum self-locking of the claw arms, the inclined surfaces 19, 23 and / or 20, 24 can be curved slightly convex in the direction of the flat ribbon conductor.
