Definitions
- the invention relates to a contact element according to the preamble of claim 1.
- the carrier part consists of a sleeve and the contact springs are inclined with respect to the sleeve axis with their bent ends fixed on the sleeve edge. Since the contact springs occupy a position in which they run according to the family of generators of a rotation hyperboloid, they have - when considering an axial section through the sleeve equipped with the contact springs - the smallest mutual diagonal distance in their central area; there are consequently the contact points at which the contact pin comes into electrically conductive contact with the contact springs.
- the contact springs are connected at least at one end in a metallically conductive manner to a mat-like contact spring unit and transferred in a radially curved state, before this unit is rolled into a cylindrical shape that allows easy fixing on the separate carrier part.
- the disadvantages that arise in the manufacture of known contact elements (DE-OS 25 58 003), in which a contact spring mat is used, which consists of a meandering bent contact spring wire, are eliminated.
- the contact spring wire sections running parallel to one another are in fact connected to one another via curved sections; Since a certain radius of curvature cannot be fallen below in practice in the case of an arcuate curvature, it is not possible to fall below a predetermined minimum distance between the contact spring wire sections. In addition, the difficult handling the contact spring mat was found to be disadvantageous due to its inevitable elasticity.
- the arcuately curved sections resist a bend around an axis parallel to the contact spring wire sections.
- the object of the invention is to create a contact element of the type mentioned at the outset which is particularly simple and which can be produced at low cost, preferably for connectors requiring little space but having a high current carrying capacity with small insertion forces.
- the contact spring socket according to the invention in which this object is achieved, is characterized essentially by the features highlighted in the characterizing part of claim 1.
- Such a contact element can be produced with wire-shaped metal strips to form the support part and support part, wherein the spacer webs can also be formed from wire material, which form the flat chambers after their deformation.
- the two metal strips with the spacer webs are punched as a unit from contact sheet metal.
- the use of two metal strips made of very thin sheet metal connected to one another by deformed spacers, each forming the carrier part or the support part, is associated with the advantage that the supply and fixing of the contact springs in the flat state of these strips, ie in a comparatively simple and convenient manner, fully automatically can be done.
- the contact element having the marked structure forms the essential basic component in the production of flat or cylindrical contact sockets or Connector pins that provide perfect contact with a minimal contact resistance and yet only a relatively low insertion force is required during the insertion process.
- the contact element is therefore particularly suitable for multiple plug connectors.
- the contact element to form a plug pin or a contact spring socket if the two metal strips forming the carrier part and the support part have an axis extending transversely to the course of the strips and at a distance from them are bent into a substantially cylindrical shape.
- the contact element can then be given the desired cylindrical sleeve shape by simple bending.
- the carrier part-support part unit equipped with the contact springs can be assigned a socket body or pin body, the diameter of which thus corresponds to the diameter of the spacer webs bent out of the plane of the support part and support part - of course after transfer of the support part.
- Support part unit in cylindrical sleeve shape - can vote that the latter can be pushed or pushed into the socket body or on the pin body with elastic deformation of the spacers. This ensures a particularly good current transfer from the contact springs to the socket body.
- the contact springs are provided with a radial curvature towards the rear in their central region between the support part and the support part in order to ensure contact.
- This curvature can be dispensed with if the contact springs to ensure contact in their central region located between the support part and the support part run obliquely with respect to the extension of the support part and the support part, but parallel to the corresponding obliquely oriented spacer bars.
- the oblique course of the contact springs in question ensures that when the metal strips forming the carrier part and the supporting part are bent into the cylindrical sleeve shape mentioned, the contact springs assume a position corresponding to that in the known contact spring bushings mentioned at the outset, in which compact sleeves are obtained from the outset operated to fix the contact springs. It is very useful if the contact springs are not only firmly connected to the support part but also to the support part.
- the spring force in this embodiment depends on the strength and the number of spacers between the support part and the support part, since these determine the distance between the parts holding the contact springs at both ends, namely the support part and the support part.
- the axis, around which the two carrier strips are bent to form a contact bush extends on the rear side and if the contact bush is assigned a socket body which serves to receive it and on which the spacer webs are supported .
- the socket body can comprise a sleeve which is cylindrically shaped from sheet metal and into which the contact socket can be inserted. This embodiment offers the possibility of a radial deformation of the socket body which serves to fix the contact socket.
- a variant can also be implemented in which a socket body in the form of a rotated sleeve is used to accommodate the contact socket.
- the contact element can also be used in an advantageous manner if the axis around which the two carrier strips are bent to form a contact pin extends on the front side and if the contact pin is assigned a pin body serving to receive it, on which the spacers are supported.
- the spacers which resiliently rest on the outside of the pin body, ensure perfect current transfer from the contact element to the pin body.
- socket or pin body has a radially directed overlapping, radially directed, support element which supports the contact springs with their free ends Leading edge includes.
- a socket housing with a flat recess is expediently used, into which the two metal strips with the spacer webs and the radially curved contact springs are inserted and fixed in advance with the metal strip forming the carrier part in such a way that the Support spacer bars on one of the two flat walls so that the contact springs protrude into the recess and that the metal strip forming the support part runs near the mouth of the recess.
- the metal strip forming the support part is provided with a widened edge which has been brought into the distance.
- the contact element 1 for electrical connectors comprises a plurality of juxtaposed contact springs 2 formed by sections of a contact spring wire, which at one end - in Fig. 1 at the lower end - on a carrier part 3 by soldering or welding , preferably laser welding are set. In their central region 4 they have a contact point which serves to make contact with a counter-contact piece, which is not illustrated in any more detail, as will be explained in more detail below.
- a support part 5 formed by a second metal strip extends at a distance parallel to the support part 3 formed by a first metal strip. This support part 5 is connected to the support part 3 via spacer webs 6 to form a structural unit, namely the two are the support part 3 and that Supporting part 5 forming metal strips with the spacers 6 punched out of contact sheet.
- the spacer webs 6 are bent out of the common plane of the support part and the support part to the front, with the support part 3 and the support part 5 approaching one another. They are transferred to a position in which two successive spacer webs 6 laterally delimit a flat chamber.
- 4 contact springs 2 are arranged next to one another in mutually parallel planes which enclose a right angle with the common plane of support part 3 and support part 5, even when the contact springs 2 are used to secure them the contact in their central region 4 between the support part 3 and the support part 5 are provided with a radial curvature towards the rear.
- the two metal strips forming the support part 3 and the support part 5 are bent into an essentially cylindrical shape about an axis extending transversely to the course of the strips and at a distance from them.
- the axis about which the two carrier strips are bent extends on the rear side, so that a contact socket is formed from the contact element.
- the axis around which the two carrier strips are bent naturally coincides with the contact socket axis.
- the contact socket is assigned a socket body 7 which serves to receive it. The spacer webs 6 are supported on this.
- the socket body 7 comprises a sleeve which is cylindrically shaped from sheet metal.
- the contact socket formed by a cylindrically shaped section of the contact element 1 can be inserted into this. Due to the resilient contact of the spacer webs 6 on the socket body 7, a perfect current transfer from the socket body 7 to the contact socket or vice versa is ensured.
- two support part-support part-spacer units in the axial direction adjoin one another to form a double unit which enables use as a double bushing.
- the contact springs 2 which extend continuously over both units, are connected in the central double socket region 8 to the associated carrier part 3.
- the free ends of the contact springs 2 lie in the region of the two support parts 5 of the double socket on the latter.
- the socket body 7 comprises a rotated sleeve for receiving the contact socket.
- the socket body 7 according to FIG. 5 is assigned a centrally projecting pin 10 at its end which faces the conductor connecting piece 9 which is integrally connected to it. This pin 10 delimits an annular groove with the socket body 7, into which the contact socket with its carrier part end can be inserted.
- the carrier part 3 is fixed to the ends of the contact springs 2 of the socket body on the conductor connector 9.
- Fig. 3 shows a contact element 1 modified embodiment.
- the contour springs 2 are arranged obliquely, in order to ensure contact in their intermediate carrier part 3 and support part 5, with respect to the extension of the carrier part and the support part 5, but are arranged parallel to the corresponding obliquely oriented spacer webs 6. If this contact element 1 is also converted into a cylindrical shape, then the contact springs 2 run in accordance with the family of generators of a rotation hyperboloid. Accordingly, the contact points at which the contact pin (not shown in more detail) comes into electrically conductive contact are located in its central region 4 even without a preceding curvature. In this embodiment, the contact springs 2 can be firmly connected not only to the carrier part 3, but also to the support part 5.
- FIG. 8 illustrates a plug pin with a pin body 11 and a contact pin bent cylindrically out of the contact element 1.

Accordingly, the spacer webs 6 extend on the side facing the pin body 11 in such a way that the spacer webs 6 are supported on the pin body 11, as a result of which a perfect current transfer from the contact element 1, which is in the form of a contact pin, to the conductor connecting piece 9 of the pin body 11 is ensured.
- FIG. 4 illustrates how the contact element 1 according to FIGS. 1 and 2, but with curved contact springs 2, can be used without prior conversion into cylindrical socket or pin form to form a flat contact spring socket 12.

Description
Die Erfindung bezieht sich auf ein Kontaktelement gemäß dem Oberbegriff des Anspruches 1.The invention relates to a contact element according to the preamble of
Bei einem bekannten automatisch herstellbaren, buchsenförmigen Kontaktelement dieser Art (DE-OS 15 90 124) besteht das Trägerteil aus einer Hülse und die Kontaktfedern sind schräg in Bezug auf die Hülsenachse verlaufend mit ihren umgebogenen Enden am Hülsenrand festgelegt. Da die Kontaktfedern eine Lage einnehmen, in der sie entsprechend der Schar von Erzeugenden eines Umdrehungshyperboloids verlaufen, weisen sie - bei Betrachtung eines Axialschnitts durch die mit den Kontaktfedern bestückte Hülse - etwa in ihrem mittleren Bereich den kleinsten gegenseitigen Diagonalabstand auf;
dort befinden sich folglich die Kontaktstellen, an denen der Kontaktstift mit den Kontaktfedern in elektrisch leitende Berührung gelangt.In a known, automatically produced, socket-shaped contact element of this type (DE-OS 15 90 124), the carrier part consists of a sleeve and the contact springs are inclined with respect to the sleeve axis with their bent ends fixed on the sleeve edge. Since the contact springs occupy a position in which they run according to the family of generators of a rotation hyperboloid, they have - when considering an axial section through the sleeve equipped with the contact springs - the smallest mutual diagonal distance in their central area;
there are consequently the contact points at which the contact pin comes into electrically conductive contact with the contact springs.
Als nachteilig hat sich bei diesen bekannten Kontaktfederbuchsen die Tatsache erwiesen, daß für die Festlegung und Lagesicherung der Kontaktfedern eine relativ massive Hülse benötigt wird, in die nur wenige Kontaktfedern nacheinander eingebracht werden können, um anschließend an deren Stirnseiten in aufwendiger Weise fixiert zu werden. Diese Schwierigkeiten ergeben sich vor allem bei angestrebter Kleinbauweise von Kontaktfederbuchsen mit einem Durchmesser kleiner als 1 mm.A disadvantage of these known contact spring bushings has been the fact that a relatively solid sleeve is required for the fixing and securing of the contact springs, in which only a few contact springs can be inserted one after the other, in order to subsequently be fixed in a complex manner on their end faces. These difficulties arise above all in the case of the desired small construction of contact spring bushes with a diameter of less than 1 mm.
Bei einem Kontaktelement in Form einer Kontaktfederbuchse bzw. eines gefederten Steckerstiftes gemäß einer älteren, nicht vorveröffentlichten Anmeldung (P 36 08 276.7), sind die Kontaktfedern mindestens an ihren einen Enden metallisch leitend zu einer mattenartigen Kontaktfedereinheit quer miteinander verbunden und in radial gewölbten Zustand übergeführt, bevor diese Einheit in eine das leichte Festlegen am gesonderten Trägerteil ermöglichende zylindrische Form gerollt ist. Auf diese Weise werden die Nachteile beseitigt, die sich bei Herstellung vorbekannter Kontaktelemente (DE-OS 25 58 003) ergeben, bei denen man sich einer Kontaktfedermatte bedient, die aus mäanderförmig gebogenem Kontaktfederdraht besteht. Die parallel zueinander verlaufenden Kontaktfederdrahtabschnitte stehen nämlich miteinander über bogenförmig gekrümmte Abschnitte in Verbindung; da ein bestimmter Krümmungsradius bei bogenförmiger Krümmung in der Praxis nicht unterschritten werden kann, läßt sich ein vorbestimmter Mindestabstand der Kontaktfederdrahtabschnitte voneinander nicht unterschreiten. Außerdem hat sich die schwierige Handhabung der Kontaktfedermatte aufgrund ihrer zwangsläufig gegebenen Dehnbarkeit als nachteilig herausgestellt. Die bogenförmig gekrümmten Abschnitte widersetzen sich nämlich einer Biegung um eine Achse parallel zu den Kontaktfederdrahtabschnitten.In the case of a contact element in the form of a contact spring socket or a spring-loaded plug pin according to an older, not previously published application (P 36 08 276.7), the contact springs are connected at least at one end in a metallically conductive manner to a mat-like contact spring unit and transferred in a radially curved state, before this unit is rolled into a cylindrical shape that allows easy fixing on the separate carrier part. In this way, the disadvantages that arise in the manufacture of known contact elements (DE-OS 25 58 003), in which a contact spring mat is used, which consists of a meandering bent contact spring wire, are eliminated. The contact spring wire sections running parallel to one another are in fact connected to one another via curved sections; Since a certain radius of curvature cannot be fallen below in practice in the case of an arcuate curvature, it is not possible to fall below a predetermined minimum distance between the contact spring wire sections. In addition, the difficult handling the contact spring mat was found to be disadvantageous due to its inevitable elasticity. The arcuately curved sections resist a bend around an axis parallel to the contact spring wire sections.
Der Erfindung liegt die Aufgabe zugrunde, ein besonders einfach ausgebildetes und mit geringen Gestehungskosten herstellbares Kontaktelement der eingangs genannten Art,vorzugsweise für Steckverbinder geringen Raumbedarfs, jedoch hoher Strombelastbarkeit bei dennoch kleinen Steckkräften zu schaffen.The object of the invention is to create a contact element of the type mentioned at the outset which is particularly simple and which can be produced at low cost, preferably for connectors requiring little space but having a high current carrying capacity with small insertion forces.
Die Kontaktfederbuchse nach der Erfindung, bei der diese Aufgabe gelöst ist, zeichnet sich im wesentlichen durch die im kennzeichnenden Teil des Anspruches 1 herausgestellten Merkmale aus. Ein derartiges Kontaktelement läßt sich mit drahtförmigen Metallstreifen zur Bildung von Trägerteil und Stützteil herstellen, wobei auch die Distanzstege aus Drahtmaterial gebildet sein können, die nach ihrer Verformung die flachen Kammern bilden. Besonders zweckmäßig ist es jedoch, wenn die beiden Metallstreifen mit den Distanzstegen als Baueinheit aus Kontaktblech gestanzt sind.The contact spring socket according to the invention, in which this object is achieved, is characterized essentially by the features highlighted in the characterizing part of
Die Verwendung von zwei durch verformte Distanzstege miteinander verbundenen, jeweils das Trägerteil bzw. das Stützteil bildenden Metallstreifen aus sehr dünnem Metallblech ist mit dem Vorteil verbunden, daß die Zufuhr und Festlegung der Kontaktfedern in flachem Zustand dieser Streifen, d.h. auf vergleichsweise einfache und bequeme Weise vollautomatisch erfolgen kann. Das den gekennzeichneten Aufbau aufweisende Kontaktelement bildet das wesentliche Grundbauteil bei Herstellung von flachen oder zylindrischen Kontaktbuchsen bzw. Steckerstiften, bei denen eine einwandfreie Kontaktgabe mit einem minimalen Übergangswiderstand gegeben und dennoch beim Steckvorgang nur eine relativ geringe Steckkraft benötigt wird. Insbesondere für Vielfachsteckverbinder ist deshalb das Kontaktelement in besonderem Maße geeignet.The use of two metal strips made of very thin sheet metal connected to one another by deformed spacers, each forming the carrier part or the support part, is associated with the advantage that the supply and fixing of the contact springs in the flat state of these strips, ie in a comparatively simple and convenient manner, fully automatically can be done. The contact element having the marked structure forms the essential basic component in the production of flat or cylindrical contact sockets or Connector pins that provide perfect contact with a minimal contact resistance and yet only a relatively low insertion force is required during the insertion process. The contact element is therefore particularly suitable for multiple plug connectors.
Als sehr vorteilhaft im Hinblick auf den Einsatz des Kontaktelements zur Bildung eines Steckerstiftes bzw. einer Kontaktfederbuchse hat es sich erwiesen, wenn die beiden das Trägerteil und das Stützteil bildenden Metallstreifen um eine sich quer zum Verlauf der Streifen und mit Abstand von ihnen erstreckende Achse in eine im wesentlichen zylindrische Form gebogen sind. Durch einfaches Biegen läßt sich dem Kontaktelement nämlich anschließend die gewünschte zylindrische Hülsenform geben. Dabei zeigt sich der zusätzliche Vorteil, daß sich der mit den Kontaktfedern bestückten Trägerteil-Stützteil-Einheit ein Buchsenkörper bzw. Stiftkörper zuordnen läßt, dessen Durchmesser so auf den Durchmesser der aus der Ebene von Stützteil und Trägerteil herausgebogenen Distanzstege - natürlich nach Überführung der Trägerteil-Stützteil-Einheit in zylindrische Hülsenform - abstimmen läßt, daß letztere in den Buchsenkörper bzw. auf den Stiftkörper unter elastischer Verformung der Distanzstege ein- bzw. aufschiebbar ist. Dadurch ist ein besonders guter Stromübergang von den Kontaktfedern zum Buchsenkörper sichergestellt.It has proven to be very advantageous with regard to the use of the contact element to form a plug pin or a contact spring socket if the two metal strips forming the carrier part and the support part have an axis extending transversely to the course of the strips and at a distance from them are bent into a substantially cylindrical shape. The contact element can then be given the desired cylindrical sleeve shape by simple bending. This shows the additional advantage that the carrier part-support part unit equipped with the contact springs can be assigned a socket body or pin body, the diameter of which thus corresponds to the diameter of the spacer webs bent out of the plane of the support part and support part - of course after transfer of the support part. Support part unit in cylindrical sleeve shape - can vote that the latter can be pushed or pushed into the socket body or on the pin body with elastic deformation of the spacers. This ensures a particularly good current transfer from the contact springs to the socket body.
Als besonders zweckmäßig hat es sich in weiterer Ausbildung herausgestellt, wenn die Kontaktfedern zur Sicherstellung der Kontaktgabe in ihrem zwischen Trägerteil und Stützteil befindlichen mittleren Bereich mit einer radialen Wölbung zur Rückseite hin versehen sind.In a further development, it has proven to be particularly expedient if the contact springs are provided with a radial curvature towards the rear in their central region between the support part and the support part in order to ensure contact.
Auf diese Wölbung kann verzichtet werden, wenn die Kontaktfedern zur Sicherstellung der Kontaktgabe in ihrem zwischen Trägerteil und Stützteil befindlichen mittleren Bereich in Bezug auf die Erstreckung von Trägerteil und Stützteil schräg, jedoch parallel zu den entsprechend schräg ausgerichteten Distanzstegen verlaufen. In diesem Fall stellt der fragliche schräge Verlauf der Kontaktfedern sicher, daß beim Biegen der das Trägerteil und das Stützteil bildenden Metallstreifen in die genannte zylindrische Hülsenform die Kontaktfedern eine Lage entsprechend derjenigen in den eingangs erwähnten bekannten Kontaktfederbuchsen einnehmen, bei denen man sich von vornherein kompakter Hülsen zur Fixierung der Kontaktfedern bedient. Dabei ist es sehr zweckmäßig, wenn die Kontaktfedern nicht nur mit dem Trägerteil sondern auch mit dem Stützteil fest verbunden sind. Die Federkraft ist bei dieser Ausführung von der Stärke und der Zahl der Distanzstege zwischen Trägerteil und Stützteil abhängig, da diese den Abstand der die Kontaktfedern beidendig eingespannt haltenden Teile, nämlich Trägerteil und Stützteil, bestimmen.This curvature can be dispensed with if the contact springs to ensure contact in their central region located between the support part and the support part run obliquely with respect to the extension of the support part and the support part, but parallel to the corresponding obliquely oriented spacer bars. In this case, the oblique course of the contact springs in question ensures that when the metal strips forming the carrier part and the supporting part are bent into the cylindrical sleeve shape mentioned, the contact springs assume a position corresponding to that in the known contact spring bushings mentioned at the outset, in which compact sleeves are obtained from the outset operated to fix the contact springs. It is very useful if the contact springs are not only firmly connected to the support part but also to the support part. The spring force in this embodiment depends on the strength and the number of spacers between the support part and the support part, since these determine the distance between the parts holding the contact springs at both ends, namely the support part and the support part.
Bei Bildung von Kontaktfederbuchsen hat es sich als günstig erwiesen, wenn sich die Achse, um die die beiden Trägerstreifen zur Bildung einer Kontaktbuchse gebogen sind, auf der Rückseite erstreckt und wenn der Kontaktbuchse ein ihrer Aufnahme dienender Buchsenkörper zugeordnet ist, an dem sich die Distanzstege abstützen. Dabei kann der Buchsenkörper eine aus Metallblech zylindrisch geformte Hülse umfassen, in die die Kontaktbuchse einschiebbar ist. Diese Ausführung bietet die Möglichkeit einer der Festlegung der Kontaktbuchse dienenden radialen Verformung des Buchsenkörpers.When contact spring bushings are formed, it has proven to be advantageous if the axis, around which the two carrier strips are bent to form a contact bush, extends on the rear side and if the contact bush is assigned a socket body which serves to receive it and on which the spacer webs are supported . The socket body can comprise a sleeve which is cylindrically shaped from sheet metal and into which the contact socket can be inserted. This embodiment offers the possibility of a radial deformation of the socket body which serves to fix the contact socket.
Es ist jedoch auch eine Variante ausführbar, bei der man sich eines Buchsenkörpers in Form einer gedrehten Hülse für die Aufnahme der Kontaktbuchse bedient.However, a variant can also be implemented in which a socket body in the form of a rotated sleeve is used to accommodate the contact socket.
Eine vorteilhafte Erweiterung der Einsatzmöglichkeit des Kontaktelements für die Herstellung von Doppelbuchsen ist bei Verwendung der Merkmale des Anspruches 10 gegeben.An advantageous extension of the use of the contact element for the production of double sockets is given when using the features of
Bei Bildung von gefederten Steckerstiften kann das Kontaktelement ebenfalls in vorteilhafter Weise eingesetzt werden, wenn sich die Achse, um die die beiden Trägerstreifen zur Bildung eines Kontaktstiftes gebogen sind, auf der Vorderseite erstreckt und wenn dem Kontaktstift ein seiner Aufnahme dienender Stiftkörper zugeordnet ist, an dem sich die Distanzstege abstützen. Auch hier sorgen die elastisch an der Stiftkörperaußenseite anliegenden Distanzstege für einen einwandfreien Stromübergang vom Kontaktelement zum Stiftkörper.When spring-loaded plug pins are formed, the contact element can also be used in an advantageous manner if the axis around which the two carrier strips are bent to form a contact pin extends on the front side and if the contact pin is assigned a pin body serving to receive it, on which the spacers are supported. Here, too, the spacers, which resiliently rest on the outside of the pin body, ensure perfect current transfer from the contact element to the pin body.
Sowohl bei der Schaffung von zylindrischen Kontaktfederbuchsen wie auch bei der Herstellung von gefederten Steckerstiften hat es sich als vorteilhaft erwiesen, wenn der Buchsen- bzw. Stiftkörper einen das zylindrisch geformte Stützteil, an dem sich die Kontaktfedern mit ihren freien Enden abstützen, übergreifenden, radial gerichteten Führungsrand umfaßt.Both in the creation of cylindrical contact spring bushings as well as in the manufacture of spring-loaded plug pins, it has proven to be advantageous if the socket or pin body has a radially directed overlapping, radially directed, support element which supports the contact springs with their free ends Leading edge includes.
Bei der Bildung einer flachen Kontaktfederbuchse mit Hilfe des erfindungsgemäßen Kontaktelements findet zweckmäßigerweise ein Buchsengehäuse mit einer flachen Ausnehmung Anwendung, in das die beiden Metallstreifen mit den Distanzstegen sowie den radial gewölbten Kontaktfedern derart mit dem das Trägerteil bildenden Metallstreifen voran eingeführt und festgelegt sind, daß sich die Distanzstege an einer der beiden flachen Wände abstützen, daß die Kontaktfedern in die Ausnehmung vorstehen und daß der das Stützteil bildende Metallstreifen in der Nähe der Mündung der Ausnehmung verläuft.When forming a flat contact spring bushing with the aid of the contact element according to the invention, a socket housing with a flat recess is expediently used, into which the two metal strips with the spacer webs and the radially curved contact springs are inserted and fixed in advance with the metal strip forming the carrier part in such a way that the Support spacer bars on one of the two flat walls so that the contact springs protrude into the recess and that the metal strip forming the support part runs near the mouth of the recess.
Um sicherzustellen, daß die freien Kontaktfederenden beim Einführen des Gegenkontakts von letzterem nicht stirnseitig berührt und beschädigt werden können, hat es sich als zweckmäßig erwiesen, wenn der das Stützteil bildende Metallstreifen mit einem in die Distanzstegebene übergeführten Verbreiterungsrand versehen ist.In order to ensure that the free contact spring ends cannot be touched and damaged on the end face when the counter-contact is inserted by the latter, it has proven to be expedient if the metal strip forming the support part is provided with a widened edge which has been brought into the distance.

Aus der Zeichnung ergibt sich, daß das Kontaktelement 1 für elektrische Steckverbinder eine Vielzahl von nebeneinander angeordneten, durch Abschnitte eines Kontaktfederdrahtes gebildeten Kontaktfedern 2 umfaßt, die an ihrem einen Ende-in Fig. 1 am unteren Ende - an einem Trägerteil 3 durch Löten oder Schweißen, vorzugsweise Laser-Verschweißung festgelegt sind. In ihrem mittleren Bereich 4 weisen sie eine der Kontaktgabe mit einem nicht näher veranschaulichten Gegenkontaktstück dienende Kontaktstelle auf, wie nachstehend noch näher erläutert wird. Parallel zu dem durch einen ersten Metallstreifen gebildeten Trägerteil 3 erstreckt sich im Abstand ein durch einen zweiten Metallstreifen gebildetes Stützteil 5. Dieses Stützteil 5 ist mit dem Trägerteil 3 über Distanzstege 6 zu einer Baueinheit verbunden, und zwar sind die beiden das Trägerteil 3 bzw. das Stützteil 5 bildenden Metallstreifen mit den Distanzstegen 6 aus Kontaktblech gestanzt.From the drawing it follows that the
Wie aus Fig. 2 ersichtlich, sind die Distanzstege 6 unter gegenseitiger Annäherung von Trägerteil 3 und Stützteil 5 aus der gemeinsamen Ebene von Trägerteil und Stützteil zur Vorderseite herausgebogen. Sie sind in eine Position übergeführt, in der jeweils zwei aufeinanderfolgende Distanzstege 6 eine flache Kammer seitlich begrenzen. In in den Fig. 1 bzw. 3 veranschaulichten Ausführungsbeispielen sind jeweils 4 Kontaktfedern 2 nebeneinander in zueinander parallelen Ebenen angeordnet, die einen rechten Winkel mit der gemeinsamen Ebene von Trägerteil 3 und Stützteil 5 einschließen, und zwar auch dann, wenn die Kontaktfedern 2 zur Sicherstellung der Kontaktgabe in ihren zwischen Trägerteil 3 und Stützteil 5 befindlichen mittleren Bereich 4 mit einer radialen Wölbung zur Rückseite hin versehen sind.As can be seen from FIG. 2, the
Wie die Fig. 5 bis 8 zeigen, sind die beiden das Trägerteil 3 und das Stützteil 5 bildenden Metallstreifen um eine sich quer zum Verlauf der Streifen und mit Abstand von ihnen erstreckende Achse in eine im wesentlichen zylindrische Form gebogen. Im Falle der Fig. 5 bis 7 erstreckt sich die Achse, um die die beiden Trägerstreifen gebogen sind, auf der Rückseite, so daß aus dem Kontaktelement eine Kontaktbuchse gebildet wird. Die Achse, um die die beiden Trägerstreifen gebogen sind, fällt natürlich mit der Kontaktbuchsenachse zusammen. Der Kontaktbuchse ist im Falle der Fig. 5 und 6 ein ihrer Aufnahme dienender Buchsenkörper 7 zugeordnet. An diesem stützen sich die Distanzstege 6 ab.5 to 8 show, the two metal strips forming the support part 3 and the
Im Falle der Ausführung gemäß der rechten Hälfte der Fig. 5 umfaßt der Buchsenkörper 7 eine aus Metallblech zylindrisch geformte Hülse. In diese ist die durch einen zylindrisch geformten Abschnitt des Kontaktelements 1 gebildete Kontaktbuchse einschiebbar. Aufgrund der elastisch nachgiebigen Anlage der Distanzstege 6 am Buchsenkörper 7 ist ein einwandfreier Stromübergang vom Buchsenkörper 7 auf die Kontaktbuchse, bzw. umgekehrt, gewährleistet.In the case of the embodiment according to the right half of FIG. 5, the socket body 7 comprises a sleeve which is cylindrically shaped from sheet metal. The contact socket formed by a cylindrically shaped section of the
Bei der Ausführung nach Fig. 6 sind zwei Trägerteil-Stützteil-Distanzsteg-Einheiten in Axialrichtung aneinander angrenzend zu einer den Einsatz als Doppelbuchse ermöglichenden Doppeleinheit zusammengefaßt. In diesem Fall sind die sich durchgehend über beide Einheiten erstreckenden Kontaktfedern 2 im zentralen Doppelbuchsen-Bereich 8 mit dem zugehörigen Trägerteil 3 verbunden. Die freien Enden der Kontaktfedern 2 liegen im Bereich der beiden Stützteile 5 der Doppelbuchse an letztere an.In the embodiment according to FIG. 6, two support part-support part-spacer units in the axial direction adjoin one another to form a double unit which enables use as a double bushing. In this case, the contact springs 2, which extend continuously over both units, are connected in the central double socket region 8 to the associated carrier part 3. The free ends of the contact springs 2 lie in the region of the two
Sowohl bei der Doppelbuchse nach Fig. 6 wie auch bei der einfachen Kontaktfederbuchse nach Fig. 5, linke Hälfte, umfaßt der Buchsenkörper 7 eine gedrehte Hülse für die Aufnahme der Kontaktbuchse. Dem Buchsenkörper 7 gemäß Fig. 5 ist an seinem Ende, das dem mit ihm einstückig verbundenen Leiteranschlußstück 9 zugewandt ist, ein zentral vorspringender Stift 10 zugeordnet. Dieser Stift 10 begrenzt mit dem Buchsenkörper 7 eine Ringrille, in die die Kontaktbuchse mit ihrem Trägerteilende einschiebbar ist. Durch eine radiale, nach innen gerichtete Verformung des Buchsenkörpers 7 ist das Trägerteil 3 mit den an ihm festgelegten Enden der Kontaktfedern 2 des Buchsenkörpers am Leiteranschlußstück 9 festgelegt.Both the double socket according to FIG. 6 and the simple contact spring socket according to FIG. 5, left half, the socket body 7 comprises a rotated sleeve for receiving the contact socket. The socket body 7 according to FIG. 5 is assigned a centrally projecting
Fig. 3 zeigt ein Kontaktelement 1 abgewandelter Ausführung. Bei dieser sind die Kontaltfedern 2 zur Sicherstellung der Kontaktgabe in ihrem Zwischenträgerteil 3 und Stützteil 5 befindlichen mittleren Bereich 4 in Bezug auf die Erstreckung von Trägerteil und Stützteil schräg, jedoch parallel zu den entsprechend schräg ausgerichteten Distanzstegen 6 angeordnet. Wird auch dieses Kontaktelement 1 in Zylinderform übergeführt, dann verlaufen die Kontaktfedern 2 entsprechend der Schar von Erzeugenden eines Umdrehungshyperboloids. Dementsprechend befinden sich in ihrem mittleren Bereich 4 auch ohne eine vorausgehende Wölbung die Kontaktstellen, an denen der nicht näher veranschaulichte Kontaktstift mit den Kontaktfedern in elektrisch leitende Berührung gelangt. Bei dieser Ausführung können die Kontaktfedern 2 nicht nur mit dem Trägerteil 3, sondern auch mit dem Stützteil 5 fest verbunden sein.Fig. 3 shows a
Fig. 8 veranschaulicht einen Steckerstift mit einem Stiftkörper 11 sowie einem aus dem Kontaktelement 1 zylindrisch gebogenen Kontaktstift. In diesem Fall verläuft die Achse, um die die beiden Metallstreifen, nämlich Trägerteil 3 und Stützteil 5 gebogen sind, auf der Vorderseite. Dementsprechend erstrecken sich die Distanzstege 6 auf der dem Stiftkörper 11 zugewandten Seite, und zwar so, daß sich die Distanzstege 6 am Stiftkörper 11 abstützen, wodurch ein einwandfreier Stromübergang vom in die Form eines Kontaktstifts übergeführten Kontaktelement 1 zum Leiteranschlußstück 9 des Stiftkörpers 11 gewährleistet ist.FIG. 8 illustrates a plug pin with a pin body 11 and a contact pin bent cylindrically out of the
In Fig. 4 ist veranschaulicht, wie das Kontaktelement 1 gemäß den Fig. 1 und 2, jedoch mit gewölbten Kontaktfedern 2 ohne vorherige Überführung in zylindrische Buchsen- bzw. Stiftform zur Bildung einer Flachkontaktfederbuchse 12 verwendbar ist. Zu diesem Zweck ist dem Kontaktelement 1 ein Buchsengehäuse 13 mit Leiteranschlußstück 9 sowie einer flachen Ausnehmung 14 zugeordnet. In diese Ausnehmung 14 sind die beiden Metallstreifen, nämlich das Trägerteil 3 und das Stützteil 5 mit den Distanzstegen 6 sowie den radial gewölbten Kontaktfedern 2 derart mit dem das Trägerteil 3 bildenden Metallstreifen voran eingeführt und in ihr festgelegt. Die Distanzstege 6 stützen sich dabei an der unteren Wand 15 der beiden flachen Wände 15, 16 des Buchsengehäuses 13 ab. Die gewölbten Kontaktfedern stehen dementsprechend in die Ausnehmung 14 nach oben vor. Der das Stützteil 5 bildende Metallstreifen verläuft in der Nähe der Mündung der Ausnehmung 14. Zum Schutz der freien Kontaktfederenden gegen Berührung mit dem nicht näher veranschaulichten Gegenkontakt bei dessen Einführung in die Ausnehmung 14 ist der das Stützteil 5 bildende Metallstreifen mit einem in die Distanzstegebene übergeführten Verbreiterungsrand 17 versehen. An die flache Ausnehmung 14 schließt sich ein Halteschlitz 18 an, in dem der das Trägerteil 3 bildende Metallstreifen festgelegt ist. Zur Fixierung in der flachen Ausnehmung bedient man sich zweckmäßigerweise des bekannten Punktschweißverfahrens, mit dessen Hilfe der Verbreiterungsrand 17 an der Wand 15 des Buchsengehäuses 13 festgelegt wird.FIG. 4 illustrates how the
Diesem bei der Ausführung nach Fig. 4 dem Schutz der freien Kontaktfederenden gegen Berührung mit dem Gegenkontakt dienenden Verbreiterungsrand entspricht beim Buchsen- bzw.
