Description

Muttersteckerteil für elektrische Steckverbinder Mother connector part for electrical connectors
Die Erfindung betrifft ein Muttersteckerteil eines elektrischen Steckverbinders, zumindest folgendes aufweisend:The invention relates to a mother connector part of an electrical connector, having at least the following:
wenigstens eine Kontaktbuchse mit einerseits einem Buchsenteil zur Aufnahme eines Steckerstiftes und andererseits einem Anschlußteil an dem ein elektrischer Leiter befestigbar ist, undat least one contact socket with on the one hand a socket part for receiving a plug pin and on the other hand a connecting part to which an electrical conductor can be fastened, and
wenigstens einer Kontakthülse mit einem im wesentlichen zylindrischen Federhalter und einer Vielzahl von Kontaktfedern, die wenigstens ein Stirnende des Federhalters umgreifen.at least one contact sleeve with a substantially cylindrical spring holder and a plurality of contact springs which encompass at least one end face of the spring holder.
Bei den hier in Rede stehenden Muttersteckerteilen für elektrische Steckverbinder kommt es u. a. darauf an, daß der elektrische Kontakt mit einem in die Kontaktbuchse eingeführten Kontaktstift sicher gewährleistet ist und daß auch bei häufigem Trennen der Steckverbindung die herrschenden Kräfte für die Kontaktgabe gleich bleiben.In the mother connector parts in question for electrical connectors here it comes u. a. to ensure that the electrical contact with a contact pin inserted into the contact socket is reliably ensured and that the prevailing forces for making contact remain the same even when the plug connection is frequently disconnected.
Die bekannten Kontaktbuchsen für Muttersteckerteile sind mehrteilig ausgeführt, d. h. die Kontaktbuchse ist aus mehreren Teilen zusammengesetzt. Insbesondere bestehen die Buchsenteile der bekannten Kontaktbuchse aus zumindest zwei Drehteilen (also durch Drehen hergestellten Teilen) , die miteinander verbunden werden müssen. Die Herstellung und Montage derartiger Kontaktbuchsen ist aufwendig und materialverbrauchend. Weiterhin kommt es bei bekannten Muttersteckerteilen von elektrischen Steckverbindern nur zu einem linienförmigen elektrischen Kontakt zwischen den Kontaktfederdrähten und dem Buchsenteil und die Kontaktfläche ist relativ klein.The known contact sockets for mother plug parts are made in several parts, ie the contact socket is composed of several parts. In particular, the socket parts of the known contact socket consist of at least two turned parts (that is, parts produced by turning) which have to be connected to one another. The manufacture and assembly of such contact sockets is complex and consumes material. Furthermore, in known mother plug parts of electrical connectors, there is only a linear electrical contact between the contact spring wires and the socket part, and the contact area is relatively small.
Die Erfindung hat das Ziel, ein Muttersteckerteil für einen elektrischen Steckverbinder so auszugestalten, daß der Herstel- lungs- und Montageaufwand möglichst gering ist und daß bei sicherer Kontaktgabe auch nach oftmaligem Gebrauch gleichbleibende Kräfte und eine größtmögliche Kontaktfläche für den Stromdurchgang gewährleistet sind.The object of the invention is to design a mother connector part for an electrical connector in such a way that the manufacturing and assembly work is as low as possible and that constant contact forces and the largest possible contact area for the passage of current are ensured even after frequent contacting.
Dieses Ziel wird bei einem Muttersteckerteil der eingangs genannten Art dadurch erreicht, daß die Kontaktbuchse aus einem einteiligen Stück eines Kontaktbleches geformt ist und daß die Kontakthülse mittels zumindest einer Nut/Feder-Anordnung verdrehsicher im Buchsenteil der Kontaktbuchse gelagert ist.This goal is achieved in a mother plug part of the type mentioned above in that the contact socket is formed from a one-piece piece of a contact plate and that the contact sleeve is mounted in the socket part of the contact socket by means of at least one tongue and groove arrangement.
Die erfindungsgemäße Gestaltung des Muttersteckerteils ermöglicht nicht nur stets im wesentlichen gleichbleibende Steck- und Ziehkräfte bei sicherer Kontaktgabe zwischen Steckerstift und Hülse, sondern auch einen geringen Materialverbrauch und eine Herstellbarkeit des Muttersteckerteils mit automatischen Maschinen, wobei das Muttersteckerteil insgesamt aus einem einteiligen Zuschnitt eines Kontaktbleches automatisch herstellbar ist. Auch ist die elektrische Kontaktgabe zwischen der Kontakthülse und dem Körper der Kontaktbuchse verbessert.The design of the mother plug part according to the invention not only enables essentially constant plug-in and pulling forces with reliable contact between the plug pin and sleeve, but also low material consumption and manufacturability of the mother plug part with automatic machines, the mother plug part being able to be produced automatically from a one-piece blank of a contact plate is. The electrical contact between the contact sleeve and the body of the contact socket is also improved.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, daß die Nut/Feder-Anordnung als Nut zumindest eine Ausbuchtung des Buchsenteils aufweist.According to a preferred embodiment of the invention, it is provided that the tongue and groove arrangement as the groove has at least one bulge in the socket part.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Nut/Feder-Anordnung als Feder einen Abschnitt zumindest einer Kontaktfeder aufweist.A further preferred embodiment of the invention provides that the tongue and groove arrangement as a spring has a section of at least one contact spring.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Kontaktfedern als Drähte ausgebildet sind. Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß der elektrische Leiter durch Quetschen oder Crimpen am Anschlußteil der Kontaktbuchse befestigbar ist.Another preferred embodiment of the invention provides that the contact springs are designed as wires. A further preferred embodiment of the invention provides that the electrical conductor can be fastened to the connecting part of the contact socket by crimping or crimping.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß der Buchsenteil der Kontaktbuchse eine Mehrzahl von radialen Ausbuchtungen aufweist, in denen Endbereiche der Kontaktfedern aufgenommen sind.Another preferred embodiment of the invention provides that the socket part of the contact socket has a plurality of radial bulges in which end regions of the contact springs are received.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Kontaktfedern unter radialer Spannung mit der Innenwand des Buchsenteils der Kontaktbuchse in Eingriff stehen.Another preferred embodiment of the invention provides that the contact springs engage the inner wall of the socket part of the contact socket under radial tension.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Kontaktfedern als Drähte ausgeformt sind, die den zylin- derförmigen Kontaktfederhalter zumindest an einem freien Stirnende mit einer Biegestelle umgreifen, wobei ein Endbereich jeder Kontaktfeder mit der Innenwand des Buchsenteils in Eingriff steht.A further preferred embodiment of the invention provides that the contact springs are formed as wires which surround the cylindrical contact spring holder with a bending point at least at one free end face, an end region of each contact spring being in engagement with the inner wall of the socket part.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß der das Buchsenteil bildende Abschnitt der Kontaktbuchse komplementäre Ausnehmungen und Vorsprünge aufweist, die jeweils an benachbarten Rändern des den Buchsenteil bildenden Kontaktbleches geformt sind, um eine geschlossene Zylinderform zu bilden.A further preferred embodiment of the invention provides that the section of the contact socket forming the socket part has complementary recesses and projections which are each formed on adjacent edges of the contact plate forming the socket part in order to form a closed cylindrical shape.
Weiter kann bei einem Muttersteckerteil der vorstehend beschriebenen Art vorgesehen sein, daß das freie Stirnende des Buchsenteils der Kontaktbuchse zumindest teilweise nach innen umgebogen ist. Mit einer solchen radialen Biegestelle steht das Buchsenteil und damit die Kontaktbuchse in zusätzlichen elektrischem Kontakt mit der Kontakthülse und es ergibt sich auch eine zusätzliche Sicherung gegen ein unerwünschtes Herausziehen der Kontakthülse aus dem Buchsenteil. Gemäß einer weiteren bevorzugten Ausgestaltung des Mutterstek- kerteils ist vorgesehen, daß der Buchsenteil der Kontaktbuchse zumindest im Bereich seiner beiden axialen Enden mit radial gerichteten Ausbuchtungen versehen ist, in die die Kontaktfedern eingreifen, wobei die Federn unter radialer Spannung stehen.Furthermore, in the case of a mother plug part of the type described above, it can be provided that the free end of the socket part of the contact socket is at least partially bent inwards. With such a radial bending point, the socket part and thus the contact socket are in additional electrical contact with the contact sleeve, and there is also an additional safeguard against undesired pulling out of the contact sleeve from the socket part. According to a further preferred embodiment of the nut connector part, it is provided that the socket part of the contact socket is provided, at least in the region of its two axial ends, with radially directed bulges into which the contact springs engage, the springs being under radial tension.
Das Buchsenteil der Kontaktbuchse kann auch über seine gesamte Länge mit sickenformigen Ausformungen versehen sein, welche nach dem Rollen des Buchsenteils die vorstehend genannten Ausbuchtungen zur Aufnahme der Kontaktfedern bilden.The socket part of the contact socket can also be provided over its entire length with bead-shaped formations, which form the aforementioned bulges for receiving the contact springs after the socket part has rolled.
Die Kontaktfedern können einerseits durch gesonderte Drähte gebildet werden, andererseits aber auch aus dem Material des im wesentlichen zylinderför igen Kontaktfederhalters selbst. Bei der letztgenannten Variante werden die Kontaktfedern aus dem Material des Kontaktfederhalters ausgestanzt und um das axiale Stirnende des Kontaktfederhalters umgebogen, so daß sie mit der Innenwand des Buchsenteils in Eingriff kommen, wie es hier ansonsten für gesonderte Drahtfedern beschrieben ist. Dabei stehen die aus dem Kontaktfederhalter ausgestanzten Federn mit einem Ende in integraler Verbindung mit dem Kontaktfederhalter.The contact springs can be formed on the one hand by separate wires, but on the other hand also from the material of the substantially zylinderför contact spring holder itself. In the latter variant, the contact springs are punched out of the material of the contact spring holder and bent over the axial face of the contact spring holder, so that they with the inner wall of the socket part come into engagement, as is otherwise described here for separate wire springs. The springs punched out of the contact spring holder are integral with the contact spring holder at one end.
Bei der Herstellung des Muttersteckerteils kann der Buchsenteil gerollt werden und, wie oben erläutert ist, durch for schlüssig ineinandergreifende Ausnehmungen und Vorsprünge können die nach dem Rollen aneinanderliegenden Längsränder des den Buchsenteil bildenden Bleches miteinander verknüpft werden. Ist zuvor die Kontakthülse in den gerollten Buchsenteil eingelegt worden, läßt sich auf diese Weise beim Herstellungsprozeß die radiale Spannung der Kontaktfedern in einfacher Weise erreichen.In the manufacture of the mother plug part, the socket part can be rolled and, as explained above, by means of interlocking interlocking recesses and projections, the longitudinal edges of the sheet metal forming the socket part, which are adjacent after the rolling, can be linked together. If the contact sleeve has previously been inserted into the rolled socket part, the radial tension of the contact springs can be achieved in a simple manner in this way during the manufacturing process.
Bevorzugt ist vorgesehen, daß die vorstehend genannten Vorsprün- ge und Ausnehmungen an den Längsrändern des den Buchsenteil bildenden Bleches zueinander exakt komplementär sind, d. h. die Vorsprünge passen genau in die entsprechenden Ausnehmungen, so daß bei fertig gerolltem Buchsenteil insgesamt eine geschlossene Zylinderform entsteht. Die Ausnehmungen an den Längsrändern des den Buchsenteil bildenden Bleches sind vorzugsweise hinter- schnitten, um eine formschlüssige Verbindung mit den in die Ausnehmungen eingreifenden Vorsprüngen zu erreichen.It is preferably provided that the above-mentioned projections and recesses on the longitudinal edges of the sheet forming the bushing part are exactly complementary to one another, ie the projections fit exactly into the corresponding recesses, so that when the bushing part is completely rolled up, a closed cylindrical shape is created. The recesses on the longitudinal edges of the sheet metal forming the socket part are preferably behind cut to achieve a positive connection with the projections engaging in the recesses.
Die Verknüpfung der beim Rollen des Buchsenteils in gegenseitige Anlage kommenden Längsränder des Bleches kann auch dadurch erreicht werden, daß an jedem der beiden Längsränder sowohl zumindest eine Ausnehmung als auch zumindest ein Vorsprung vorgesehen sind, um eine wechselseitige Verknüpfung der Längsränder zu erreichen.The connection of the longitudinal edges of the sheet that come into mutual contact when the bushing part rolls can also be achieved in that at least one recess and at least one projection are provided on each of the two longitudinal edges in order to achieve a mutual connection of the longitudinal edges.
Um das Muttersteckerteil in einem zugehörigen Gehäuse positionieren zu können, ist vorgesehen, daß das Muttersteckerteil einen Abschnitt mit reduziertem Durchmesser aufweist, so daß durch unterschiedliche Radien eine Stufe gebildet wird, mit deren Hilfe das Muttersteckerteil an einer vorgesehenen Position im Gehäuse einrastet.In order to be able to position the mother plug part in an associated housing, it is provided that the mother plug part has a section with a reduced diameter, so that a step is formed by different radii, with the aid of which the mother plug part engages in a designated position in the housing.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigt:An exemplary embodiment of the invention is described in more detail below with reference to the drawing. It shows:
Figur 1 eine Seiteneinsicht einer Kontaktbuchse für ein Muttersteckerteil ;Figure 1 is a side view of a contact socket for a mother connector part;
Figur 2 eine Ansicht einer Kontaktbuchse entsprechend Figur 1, wobei der sog. Buchsenabschnitt geschnitten ist; undFIG. 2 shows a view of a contact socket corresponding to FIG. 1, the so-called socket section being cut; and
Figur 3 einen Schnitt durch eine Kontaktbuchse gemäß Figur 1 im Bereich des Buchsenteils.3 shows a section through a contact socket according to FIG. 1 in the region of the socket part.
Das Muttersteckerteil gemäß dem dargestellten Ausführungsbei- spiel weist eine Kontaktbuchse 1 auf, die insgesamt rotations- symmetrisch um ihre Längsachse A ausgebildet ist. Die Kontaktbuchse 1 besteht insgesamt aus einem einteiligen Zuschnitt eines Bleches mit guten elektrischen Kontakteigenschaften. Die Kontaktbuchse 1 dient der elektrischen Verbindung zwischen einem Steckerstift 15 (vgl. Figur 2) und einem elektrischen Leiter 17.The mother plug part according to the exemplary embodiment shown has a contact socket 1 which is designed overall in a rotationally symmetrical manner about its longitudinal axis A. The contact socket 1 consists overall of a one-piece cut of a sheet with good electrical contact properties. The contact socket 1 serves for the electrical connection between a plug pin 15 (see FIG. 2) and an electrical conductor 17.
Die Kontaktbuchse 1 enthält als weiteres Bauteil eine Kontakthülse 2 (vgl. Figur 2) , die in ein Buchsenteil 3 der Kontaktbuchse 1 eingeführt ist. Die Kontakthülse 2 nimmt den Steckerstift 15 auf und erzeugt dabei einen durchgehenden Kontakt vom Steckerstift 15 zur Wand der Kontaktbuchse 1. Elektrisch isolierende Bauteile, die die Kontaktbuchse 1 zumindest teilweise umgeben und auch ein äußeres Gehäuse sind in der Zeichnung nicht dargestellt, da die isolierenden Teile und das Gehäuse als solche nicht den Gegenstand der Erfindung bilden.As a further component, the contact socket 1 contains a contact sleeve 2 (see FIG. 2) which is inserted into a socket part 3 of the contact socket 1. The contact sleeve 2 receives the plug pin 15 and thereby creates a continuous contact from the plug pin 15 to the wall of the contact socket 1. Electrically insulating components which at least partially surround the contact socket 1 and also an outer housing are not shown in the drawing, since the insulating parts and the housing as such does not form the subject of the invention.
Die Kontaktbuchse weist an ihrem in den Figuren obenliegenden Ende ein Anschlußteil 4 auf, das zum Anschließen des Leiters 17 dient. Hierzu ist am Leiter 17 eine Zunge 18 ausgeformt, die in das Anschlußteil 4 ragt, (vgl. die gestrichelte Linie der Zunge 18) . Durch Quetschen des Anschlußteils 14 erfolgt eine feste, elektrisch leitende Verbindung zum Leiter 17.The contact socket has a connection part 4 at its end located at the top in the figures, which serves to connect the conductor 17. For this purpose, a tongue 18 is formed on the conductor 17, which protrudes into the connecting part 4 (cf. the dashed line of the tongue 18). By squeezing the connecting part 14, a firm, electrically conductive connection to the conductor 17 takes place.
Die Kontaktbuchse 1 weist zwischen dem Buchsenteil 3 und dem Anschlußteil 4 eine Einschnürung 5 mit reduziertem Durchmesser auf. Dieser Abschnitt mit reduziertem Durchmesser dient der Positionierung der Kontaktbuchse in einem Gehäuse (nicht gezeigt) . Die Einschnürung 5 bildet gemäß den Figuren 1 und 2 an beiden Enden konische Stufen, die mit entsprechenden konischen Flächen im Gehäuse (nicht gezeigt) positionsgenau in Eingriff bringbar sind.The contact socket 1 has a constriction 5 with a reduced diameter between the socket part 3 and the connecting part 4. This section with reduced diameter is used to position the contact socket in a housing (not shown). The constriction 5 forms, according to FIGS. 1 and 2, conical steps at both ends, which can be brought into engagement with corresponding conical surfaces in the housing (not shown) in a precisely positioned manner.
Eine Kontakthülse 2 wird im Buchsenteil 3 der Kontaktbuchse 1 positioniert. Die Kontakthülse 2 weist einen zylinderförmigen Kontaktfederhalter 6 und Kontaktfedern 7 auf. Beim dargestellten Ausführungsbeispiel sind die Kontaktfedern 7 als federnde Drähte ausgebildet. Eine Vielzahl von federnden Drähten 7 erstreckt sich durch den Innenraum des Kontaktfederhalters 6. An den beiden axialen Enden des Kontaktfederhalters 6 sind die Kontaktfedern 7 umgebogen und bilden so Biegestellen 8. Die Endbereiche der Kontaktfedern 7 sind mit 8* bezeichnet. Diese Endbereiche 8' der Kontaktfedern 7 stehen in elektrischem Kontakt mit der Wand des Buchsenteils 3. Dabei stehen die Biegestellen 8 der Kontaktfedern 7 unter radialer Spannung.A contact sleeve 2 is positioned in the socket part 3 of the contact socket 1. The contact sleeve 2 has a cylindrical contact spring holder 6 and contact springs 7. In the illustrated embodiment, the contact springs 7 are designed as resilient wires. A large number of resilient wires 7 extend through the interior of the contact spring holder 6. At the two axial ends of the contact spring holder 6, the contact springs 7 are bent over and thus form bending points 8. The end regions the contact springs 7 are designated 8 *. These end regions 8 'of the contact springs 7 are in electrical contact with the wall of the socket part 3. The bending points 8 of the contact springs 7 are under radial tension.
Figur 3 zeigt einen Schnitt senkrecht zur Achse A der Kontaktbuchse 1 im Bereich eines stirnseitigen Endes des Buchsenteils 3. Gemäß Figur 3 ist das Buchsenteil 3 mit mehreren Ausbuchtungen 9 ausgeformt, in die die Endbereiche 8' der Kontaktfedern 7 eingreifen. Durch den Eingriff der Endbereiche 8' der Kontaktfedern 7 in die Ausbuchtungen 9 wird zum einen ein großflächiger elektrischer Kontakt zwischen den Kontaktfedern 7 und dem Buchsenteil 3 der Kontaktbuchse 1 erreicht und zum anderen bewirkt der Eingriff der Endbereiche 8 ' in die Ausbuchtungen 9 eine Verdrehsicherung der Kontakthülse 2 insgesamt im Buchsenteil 3. Die vorstehend beschriebene Verdrehsicherung mittels der Endbereiche 8 ' der Kontaktfedern und der Ausbuchtungen 9 wirkt in der Art einer Nut/Feder-Verbindung. Die radiale Spannung in den Kontaktfedern 7, insbesondere in deren Biegestellen 8, bewirkt insgesamt eine Verklemmung der Kontakthülse 2 im Buchsenteil 3 der Kontaktbuchse 1.FIG. 3 shows a section perpendicular to the axis A of the contact socket 1 in the region of an end face of the socket part 3. According to FIG. 3, the socket part 3 is formed with a plurality of bulges 9 into which the end regions 8 ′ of the contact springs 7 engage. Through the engagement of the end regions 8 'of the contact springs 7 in the bulges 9, on the one hand a large-area electrical contact between the contact springs 7 and the socket part 3 of the contact socket 1 is achieved and, on the other hand, the engagement of the end regions 8' in the bulges 9 ensures a rotation of the Contact sleeve 2 overall in the socket part 3. The anti-rotation device described above by means of the end regions 8 'of the contact springs and the bulges 9 acts in the manner of a tongue and groove connection. The radial tension in the contact springs 7, in particular in their bending points 8, causes a jamming of the contact sleeve 2 in the socket part 3 of the contact socket 1.
Die Ausbuchtungen 9 können sich entweder über die gesamte axiale Länge des Buchsenteils 3 erstrecken oder auch nur jeweils an den axialen Enden des Buchsenteils 3 ausgeformt sein. Die Endbereiche 8 ' der Kontaktfedern 7 können länger sein als in Figur 2 dargestellt ist.The bulges 9 can either extend over the entire axial length of the socket part 3 or can be formed only at the axial ends of the socket part 3. The end regions 8 'of the contact springs 7 can be longer than is shown in FIG. 2.
Beim dargestellten Ausführungsbeispiel sind sechs Kontaktfedern 7 in sechs entsprechenden Ausbuchtungen 9 im Buchsenteil 3 geführt. Ein Steckerstift 15 wird in Richtung des Pfeiles in den Buchsenteil 3 und in die Kontakthülse 2 eingeschoben und kommt so in elektrischen Kontakt mit den Kontaktfedern 7.In the illustrated embodiment, six contact springs 7 are guided in six corresponding bulges 9 in the socket part 3. A plug pin 15 is inserted in the direction of the arrow into the socket part 3 and into the contact sleeve 2 and thus comes into electrical contact with the contact springs 7.
Die Kontaktbuchse 1 und insbesondere deren Buchsenteil 3 können durch Rollen eines entsprechend zugeschnittenen Blechstückes hergestellt werden. Um eine geschlossene Zylinderform für das Buchsenteil 3 (vgl. Fig. 3) zu erreichen, ist vorgesehen, daß an den nach dem Rollen in gegenseitige Anlage kommenden Längsrän- dern 10, 11 des den Buchsenteil 3 bildenden Blechstückes Ausnehmungen 13 bzw. Vorsprünge 14 in der dargestellten Weise (Fig. 1) ausgeformt sind. Die Vorsprünge 14 passen komplementär in die hinterschnittenen Ausnehmungen 13, so daß sich eine ununterbrochene Oberfläche des Buchsenteils 3 ergibt.The contact socket 1 and in particular its socket part 3 can be produced by rolling a correspondingly cut piece of sheet metal. In order to achieve a closed cylindrical shape for the socket part 3 (cf. FIG. 3), it is provided that the longitudinal rims coming into mutual contact after the rolling 10, 11 of the sheet metal piece forming the socket part 3, recesses 13 or projections 14 are formed in the manner shown (FIG. 1). The projections 14 complementary fit into the undercut recesses 13, so that there is an uninterrupted surface of the socket part 3.
In Abwandlung des in den Figuren dargestellten Ausfuhrungsbeispieles kann das Buchsenteil 3 an seinem in den Figuren unten gelegenen axialen Ende zumindest teilweise leicht nach innen gebogen sein, so daß die Kontakthülse 2 im Buchsenteil 3 gesichert ist.In a modification of the exemplary embodiment shown in the figures, the socket part 3 can at least partially be slightly bent inwards at its axial end located below in the figures, so that the contact sleeve 2 is secured in the socket part 3.
In Abwandlung des vorstehend beschriebenen Ausführungsbeispieles kann die Kontakthülse 2 auch einen Kontaktfederhalter 6 aufweisen, der mit den Kontaktfedern 7 einstückig (integral) ausgebildet ist. Bei dieser Abwandlung können die Kontaktfedern z. B. durch teilweises Stanzen aus dem Kontaktfederhalter 6 herausgebogen werden, z. B. in Form einzelner Blechstreifen, die entsprechend den in den Figuren dargestellten Kontaktfedern 7 um die axialen Stirnflächen des Kontaktfederhalters herumgebogen sind und so mit der Innenwand des Buchsenteils 3 in axialen Eingriff kommen, wobei die Biegestellen unter radialer Spannung stehen. In a modification of the exemplary embodiment described above, the contact sleeve 2 can also have a contact spring holder 6 which is formed in one piece (integral) with the contact springs 7. In this modification, the contact springs z. B. bent out of the contact spring holder 6 by partial punching, for. B. in the form of individual sheet metal strips, which are bent around the axial end faces of the contact spring holder according to the contact springs 7 shown in the figures and thus come into axial engagement with the inner wall of the socket part 3, the bending points being under radial tension.
