Abstract

1. A method of producing an at least partially elastically compressable clamping zone (17) which forms a section of a pin-shaped element and which serves for forcelocking the element in a bore, wherein the clamping zone is formed by dividing the element (1) into at least two arms (8) which are connected to one another at both ends and by increasing the distance between these two arms relative to one another, characterised in that the division of the element (1) into two arms (8) is effected by means of two wedges (2, 3) which can be moved in opposite directions to one another and which have cutting edges (4) which are aligned parallel to the longitudinal axis (5) of the element (1) and have wedge angles of about 30 degrees to 60 degrees, in such a way that the wedges (2, 3) are either simultaneously pressed into the element (1), in which case the cutting edges are slightly offset relative to one another, or that the wedges (2, 3) are pressed consecutively into the element (1), in which case the cutting edges (4) are in line with one another and the element (1) is correspondingly supported on the opposite side ; and that the arms (8) which give way outwardly when the wedges (2, 3) are pressed into the element (1), are checked transversely to the direction of movement of the wedges (2, 3) by means of abutments (9) which are adapted to the curvature of the bore.

Description

Die Erfindung bezieht sich auf ein-Verfahren zur Herstellung eines wenigstens teilweise elastisch zusammendrückbaren Klemmbereiches, der einen Abschnitt eines stiftförmigen Elementes bildet und der zur kraftschlüssigen Fixierung des Elementes in einer Bohrung vorgesehen ist, wobei der Klemmbereich durch Aufteilung des Elementes in wenigstensrzwei Schenkel, die an ihren beiden Enden miteinander verbunden sind, und eine Vergrößerung des Abstandes dieser beiden Schenkel voneinander erhalten wird.The invention relates to a method for producing an at least partially elastically compressible clamping area, which forms a section of a pin-shaped element and which is provided for the non-positive fixing of the element in a bore, the clamping area by dividing the element into at least two legs their two ends are connected to each other, and an increase in the distance between these two legs is obtained.

Ein solches Verfahren ist aus der GB-PS 1 149 332 bekannt. Bei dem bekannten Verfahren wird das Element zunächst im Klemmbereich flach gedrückt. Anschließend wird der flachgedrückte Abschnitt mit einem Schlitz versehen, so daß sich zwei an ihren beiden Enden miteinander verbundene Schenkel in dem flachgedrückten Abschnitt des Elementes ergeben. Schließlich werden die Schenkel außen abgerundet, um die Außenkontur der Schenkel der Rundung der zur Aufnahme des Elementes vorgesehenen Bohrung anzupassen. Diese Anpassung der Außenkontur eines Klemmbereiches an die Rundung einer Bohrung, in die das Element eingesteckt wird, ist erforderlich, damit z.B. eine Oberflächenmetallisierung der Bohrung nicht durch das Einstecken des Elementes beschädigt werden kann.Such a method is known from GB-PS 1 149 332. In the known method, the element is first pressed flat in the clamping area. Then the flattened section is provided with a slot, so that two legs connected at their two ends in the flattened section of the Result. Finally, the legs are rounded on the outside in order to adapt the outer contour of the legs to the curvature of the bore provided for receiving the element. This adaptation of the outer contour of a clamping area to the rounding of a hole into which the element is inserted is necessary so that, for example, a surface metallization of the hole cannot be damaged by inserting the element.

Derartige Elemente bilden z.B. die mit einem Abschnitt in die Bohrungen einer Leiterplatte einzusteckenden Kontaktstifte, Kontaktmesser oder Kontaktfedern, die in vielpoligen Stift-, Messer- oder Kontaktfederleisten zusammengefasst sind.Such elements form e.g. the contact pins, contact blades or contact springs to be inserted with a section into the bores of a printed circuit board, which are combined in multi-pole pin, knife or contact spring strips.

Es ist dabei erwünscht, den Klemmmbereich auf möglichst rationelle Weise herstellen zu können und mit möglichst wenig Fertigungsschritten auszukommen.It is desirable to be able to produce the clamping area in the most rational manner possible and to get by with as few manufacturing steps as possible.

Aufgabe vorliegender Erfindung ist es daher, ein Verfahren der eingangs genannten Art so weiterzubilden, daß der Klemmbereich unter Aufrechterhaltung seiner vollen Funktionstüchtigkeit, insbesondere unter Schaffung einer der Bohrungsrundung angepaßten Außenkontur,:.in möglichst nur einem Arbeitsgang hergestellt werden kann.It is therefore an object of the present invention to develop a method of the type mentioned at the outset such that the clamping region can be produced in as little as possible in one operation while maintaining its full functionality, in particular by creating an outer contour adapted to the rounding of the bore.

Erfindungsgemäjß ergibt sich die Lösung dieser Aufgabe dadurch, daß die Aufteilung des Elementes in-zwei Schenkel durch zwei gegensinnig zueinander gewegbare Keile mit parallel zur Längsachse des Elementes ausgerichteten und einen Keilwinkel von ca. 30° bis 60° aufweisenden Keilschneiden in der Weise vorgenommen wird, daß die Keile entweder zugleich, unter geringem Versatz der Keilschneiden gegeneinander, in das Element hineingedrückt werden oder daß die Keile nacheinander mit aufeinander ausgerichteten Keilschneiden in das Element unter jeweils entsprechender Abstützung des Elementes auf der Gegenseite hineingedrückt, werden und daß die beim Eindrücken der Keile in das Element ausweichenden Schenkel quer zur Bewegungsrichtung der Keile durch der Bohrungsrundung angepaßte Widerlager abgefangen werden.According to the invention, this object is achieved in that the division of the element into two legs is carried out by means of two wedges which can be moved in opposite directions with wedge edges oriented parallel to the longitudinal axis of the element and having a wedge angle of approximately 30 ° to 60 °, that the wedges are either pressed into the element at the same time, with a slight offset of the wedge cutting edges against one another, or that the wedges are successively with one another aligned wedge cutting into the element with appropriate support of the element on the opposite side, and that the legs evading when pressing the wedges into the element are intercepted transversely to the direction of movement of the wedges by the rounding of the abutment.

Ein besonderer Vorteil dieses Verfahrens ist darin zu sehen, daß im wesentlichen ohne Rücksicht auf das Querschnittsprofil des Elementes im Klemmbereich stets nach außen abgerundete Schenkel erhalten werden, die abschnittsweise parallel zueinander verlaufen.A particular advantage of this method can be seen in the fact that, regardless of the cross-sectional profile of the element in the clamping area, legs which are rounded outward and which in sections run parallel to one another are always obtained.

Ausführungsbeispiele der Erfindung werden nachstehend anhand von acht Figuren noch näher erläutert.Exemplary embodiments of the invention are explained in more detail below with reference to eight figures.

Dabei zeigen die Figuren 1 und 2 die Herstellung des Klemmbereiches, wobei zwei gleichzeitig bewegbare Keile Verwendung finden,1 and 2 show the production of the clamping area, two wedges which can be moved simultaneously being used,

die Figuren 3 und 4 die Herstellung des Klemmbereiches unter Verwendung zweier nacheinander bewegbarer Keile,FIGS. 3 and 4 show the production of the clamping area using two wedges that can be moved in succession,

die Figuren 5, 6 .und 7 eine Seitenansicht von zwei in ein Element eingearbeiteten Klemmbereichen, die um 90° gegeneinander verdreht sind, mit den zugehörigen Querschnittsbildern undFIGS. 5, 6 and 7 show a side view of two clamping areas worked into an element, which are rotated by 90 ° relative to one another, with the associated cross-sectional images and

Die Figur 8 in Schrägsicht und stark vergrößert, die spezielle Form der auf das Element einwirkenden Keile und die sich hieraus ergebende Ausbildung der Schenkel des Elementes im Klemmbereich.Figure 8 in an oblique view and greatly enlarged, the special shape of the wedges acting on the element and the resulting formation of the legs of the element in the clamping area.

Aus den Figuren 1 bis 4 ist zu ersehen, daß die Einarbeitung eines Klemmbereiches in ein stiftförmiges Element 1, das einen quadratischen Querschnitt aufweist (der Querschnitt des Elementes kann selbstverständlich auch rund, oval, rechteckig oder vieleckig sein) mit Hilfe zweier Keile 2,3 vorgenommen wird, deren Keilschneiden 4 einen Winkel von 60° aufweisen. Die Keilschneiden 4 sind zueinander und zur Achse 5 des Elementes parallel gerichtet.It can be seen from FIGS. 1 to 4 that the incorporation of a clamping area into a pin-shaped element 1 which has a square cross section (the cross section of the element can of course also be round, oval, rectangular or polygonal) with the aid of two wedges 2, 3 is made, the wedge edges 4 have an angle of 60 °. The wedge edges 4 are directed parallel to one another and to the axis 5 of the element.

Die Keile 2,3 können entweder wie in den Figuren 1 und 2 dargestellt, gleichzeitig oder, wie aus den Figuren 3 und 4 zu ersehen, nacheinander in das Element 1 hineinbewegt werden.The wedges 2, 3 can either be moved simultaneously into the element 1, as shown in FIGS. 1 and 2, or, as can be seen from FIGS. 3 and 4, one after the other.

Wenn die Keile 2,3 zugleich in das Element mitzueinander gegenläufiger Bewegungsrichtung ihrer Keilschneiden 4 hineinbewegt werden sollen, so ist es erforderlich, wie aus den Figuren 1 und 2 zu ersehen, dieBewegungsebenen 6 der Keile 2,3 gegen eine durch die Achse 5 des Elementes 1 verlaufende Symmetrieebene 7 des Elementes 1 so zu versetzen, daß sich, wie insbesondere aus Fig. 2 zu ersehen ist, die beiden Keile 2,3 in ihrer nach dem Aufteilen des Elementes 1 in zwei Schenkel 8 erreichten Endposition mit ihren Keilschneiden 4 gegenseitig überlappen.If the wedges 2, 3 are to be simultaneously moved into the element in the opposite direction of movement of their wedge edges 4, it is necessary, as can be seen from FIGS. 1 and 2, the planes of movement 6 of the wedges 2, 3 against one through the axis 5 of the element 1 extending plane of symmetry 7 of the element 1 so that, as can be seen in particular from FIG. 2, the two wedges 2, 3 in their end position reached after dividing the element 1 into two legs 8 overlap with their wedge edges 4 .

Durch das Aufteilen des Elementes 1 im Klemmbereich in zwei Schenkel 8 mit Hilfe der Keile 2,3 wird u.a. erreicht, daß mit zunehmendem Eindringen der Keile 2,3 in das Element 1 die Schenkel 8 zunehmend auseinander bewegt werden. Diese Bewegung wird jedoch durch zwei Widerlager 9 begrenzt, die an-ihren dem Element 1 zugewandten Seiten als Halbschalen 10 ausgebildet sind, die der Rundung der Bohrung, in die das Element 1 eingesteckt werden soll, angepaßt sind, Dadurch werden die Schenkel 8 mit ihrer von der Achse 5 des Elementes 1 abgewandten Außenseite 11 durch die Keile 2,3 gegen die Rundungen 10 der Widerlager 9 gepreßt und dadurch diesen Rundungen angepaßt. Das Element hat deshalb im Klemmbereich einen Querschnitt, vgl. hierzu die Figuren 6 und 7, bei dem jeder der beiden Schenkel 8 nach außen eine der Bohrungsrundung angepaßte Außenseite 11 und eine dem gegenüberliegenden Schenkel zugewandte keilförmige Innenseite 12 besitzt, so daß der die Schenkel 8 trennende Zwischenraum 13 schmetterlingsartig ausgebildet ist.By dividing the element 1 in the clamping area into two legs 8 with the help of the wedges 2, 3 it is achieved, among other things, that the legs 8 are increasingly moved apart as the wedges 2, 3 penetrate into the element 1. However, this movement is limited by two abutments 9, which are designed on their sides facing the element 1 as half-shells 10, which are adapted to the rounding of the bore into which the element 1 is to be inserted its outer side 11 facing away from the axis 5 of the element 1 is pressed by the wedges 2, 3 against the curves 10 of the abutment 9 and thereby adapted to these curves. The element therefore has a cross section in the clamping area, cf. 6 and 7, in which each of the two legs 8 has an outer face 11 adapted to the rounding of the bore and a wedge-shaped inner face 12 facing the opposite leg, so that the space 13 separating the legs 8 is formed like a butterfly.

Werden die Keile 2, 3 nacheinander in das Element 1 hineinbewegt, vgl. hierzu insbesondere die Fig. 3 und 4, so können die Keile 2,3 mit ihren Bewegungsebenen, diese stimmen mit den Symmetrieebenen der Keilschneiden 4 überein, auf eine durch die Achse 5 des Elementes verlaufende Symmetrieebene 7 des Elementes 1 ausgerichtet werden.If the wedges 2, 3 are successively moved into the element 1, cf. 3 and 4 in particular, the wedges 2, 3 with their planes of movement, which coincide with the planes of symmetry of the wedge edges 4, can be aligned with a plane of symmetry 7 of the element 1 running through the axis 5 of the element.

Beim Hineindrücken eines der beiden Keile 2,3 muß der jeweils andere Keil durch ein Abstützorgan 14 ersetzt werden, wobei das Abstützorgan 14 ein Ausweichen des Elementes 1 in Bewegungsrichtung eines der Keile 2,3 verhindert.When one of the two wedges 2, 3 is pushed in, the other wedge must be replaced by a support member 14, the support member 14 preventing the element 1 from escaping in the direction of movement of one of the wedges 2, 3.

Die Ausformung der Außenseite 11 der Schenkel 8 wird auch bei einem nacheinander erfolgenden Eindrücken der Keile 2,3 in das Element 1 in gleicher Weise wie bei dem Verfahren nach den Fig.1 und 2 mit Hilfe zweier Widerlager 9 vorgenommen.The shaping of the outside 11 of the legs 8 is carried out in the same way as in the method according to FIGS. 1 and 2, with the aid of two abutments 9, even if the wedges 2, 3 are pressed into the element 1 one after the other.

Wie Figur 5 zeigt, können in ein Element 1 in Verlaufsrichtung des Elementes auch mehrere Klemmbereiche 15 eingearbeitet werden, wobei vorteilhaft die Klemmwirkung der aufeinanderfolgenden Klemmbereiche 15 um 900 gegeneinander versetzt wird.As Figure 5 shows, a plurality of terminal areas 15 may be incorporated in an element 1 in the extending direction of the element, wherein the clamping effect of the clamping portions 15 consecutive advantageously 90 0 is offset from each other.

Aus Fig. 8 ist zu ersehen, daß die Keile 2,3 mit ihren Keilschneiden 4 zu den Verbindungspunkten 16 der Schenkel 8 hin jeweils abgeschrägt verlaufen, so daß sich die Schenkel 8 von einem mittleren Abschnitt 17 aus, in dem die Schenkel 8 parallel zueinander in einem bestimmten Abstand voneinander verlaufen und damit den eigentlichen Klemmbereich bilden, sich kontinuierlich wieder einander nähern, also aufeinander zu verlaufen. Dies ermöglicht es, den Querschnitt des Elementes 1 gegenüber einer Bohrung, in der der Klemmbereich 15 des Elementes 1 zur Wirkung kommen soll, relativ kleiner auszubilden, so daß das Element 1 die Bohrungswände nur im Bereich 17 berührt. In diesem Bereich 1 hat das Element durch die der Rnndung der Bohrung angepaßte Außenseite 11 der Schenkel 8 eine Kontur, die optimal auf die Bohrung abgestimmt ist, Der Querschnitt des restlichen Elementes 1 kann dagegen, um z.B. einen Wrap-Stil zu erhalten, quadratisch oder rechteckig sein, jedenfalls demijeweiligen Verwendungszweck entsprechend ausgebildet sein.From Fig. 8 it can be seen that the wedges 2, 3 run with their wedge edges 4 to the connection points 16 of the legs 8 each so that the legs 8 extend from a central section 17 in which the legs 8 are parallel to each other run at a certain distance from one another and thus form the actual clamping area, continuously approach each other again, that is to say run together. This makes it possible to make the cross section of the element 1 relatively smaller compared to a bore in which the clamping area 15 of the element 1 is to come into effect, so that the element 1 only touches the bore walls in the area 17. In this area 1, the element 11 has a contour that is optimally matched to the bore due to the outer side 11 of the legs 8 that is adapted to the edge of the bore. to get a wrap style, be square or rectangular, in any case be designed according to the intended use.
