Description

Stecker mit Haltefeder für einen Erdungskontakt Plug with retaining spring for a ground contact
Die Erfindung betrifft einen Stecker mit einer Hülse und mit einem in Gebrauchsstellung in der Hülse angeordneten Isolierkörper sowie mit länglichen Kontakten, die in Lochungen oder Bohrungen des Isolierkörpers gehalten sind, wobei ein Kontakt als Erdungskontakt parallel zu den übrigen Kontakten innerhalb einer Lochung oder Bohrung angeordnet ist, welche eine seitliche Öffnung für eine elektrisch leitende Haltefeder aufweist, die den Erdungskontakt in Gebrauchsstellung in seiner Lochung oder Bohrung festlegt.The invention relates to a plug with a sleeve and with a position of use in the sleeve arranged insulator and with elongated contacts which are held in holes or holes in the insulator, wherein a contact is arranged as a grounding contact parallel to the other contacts within a perforation or bore which has a lateral opening for an electrically conductive retaining spring which defines the grounding contact in the position of use in its perforation or bore.
Ein derartiger Stecker ist aus EP 1 275 173 B1 bekannt und hat sich bewährt, weil er einfach in der Herstellung ist und bei einer einteiligen Ausbildung des Isolierkörpers die Festlegung der Kontakte, seien es Kontaktstifte, seien es Kontaktbuchsen, auf einfache Weise ermöglicht.Such a connector is known from EP 1 275 173 B1 and has proven itself, because it is simple to manufacture and in a one-piece design of the insulating fixing the contacts, be it contact pins, be it contact sockets, in a simple manner.
Dabei geht aus EP 1 275 173 B1 auch die Möglichkeit hervor, einen der Kontaktstifte mit einer Haltefeder zu erden, ihn also als Erdungskontakt zu benutzen und dabei gleichzeitig auch in axialer Richtung seines Verlaufs innerhalb des Isolierkörpers festzulegen. Die dabei vorgesehene Haltefeder weist zwei den Erdungskontakt rastend erfassende und umgreifende Federarme auf und muss nach dem Einstecken des Erdungskontakts radial durch eine seitliche Öffnung des Isolierkörpers eingesteckt werden. Dies erschwert die Montage, weil der Kontaktstift erst dann lagerichtig festgelegt ist, wenn die Haltefeder ihrerseits montiert ist. Außerdem ist die an den Federarmen vorhandene Kontaktfläche relativ klein. Es besteht deshalb die Aufgabe, einen Stecker der eingangs definierten Art zu schaffen, bei welchem die Montage des Erdungskontakts vereinfacht ist und die Kontaktfläche vergrößert sein kann.It is also apparent from EP 1 275 173 B1 the possibility of grounding one of the contact pins with a retaining spring, so to use it as a ground contact and at the same time set in the axial direction of its course within the insulator. The retaining spring provided here has two grounding detent engaging and encompassing spring arms and must be inserted after insertion of the grounding contact radially through a lateral opening of the insulator. This complicates the assembly, because the contact pin is only then fixed in the correct position when the retaining spring is mounted in turn. In addition, the existing contact surface on the spring arms is relatively small. It is therefore an object to provide a connector of the type defined, in which the mounting of the ground contact is simplified and the contact surface can be increased.
Zur Lösung dieser Aufgabe ist vorgesehen, dass die Haltefeder einen in axialer Richtung durchgängigen, in Gebrauchsstellung innerhalb der Lochung oder Bohrung des Isolierkörpers ange- ordneten Einsteckteil hat, dessen lichter Innenquerschnitt etwa dem Außenquerschnitt des im wesentlichen stiftförmigen Erdungskontakts entspricht und der sich in Gebrauchsstellung innerhalb des Isolierkörpers in Flucht oder koaxial zu der Öffnung oder Lochung des Isolierkörpers für den Erdungskontakt befindet, so dass dieser Erdungskontakt beim Einführen in seine Lochung oder Bohrung in den Einsteckteil einsteckbar ist, dass der Einsteckteil der Kontaktfeder durch die seitliche Öffnung des Isolierkörpers passt und wenigstens einen an seiner Außenseite verlaufenden Federarm trägt, der an einem freien, den Einsteckteil überragenden Ende einen radial nach innen gerichteten, in den Einsteckweg des Erdungskontakts reichenden Vorsprung hat, der den Erdungskontakt in Gebrauchsstellung fixierend beaufschlagt.To achieve this object, it is provided that the retaining spring has a plug-in part which is continuous in the axial direction and is located in the position of use within the hole or bore of the insulating body, whose inner light cross-section corresponds approximately to the outer cross-section of the substantially pin-shaped ground contact and which is in the position of use within the Insulating body in alignment or coaxial with the opening or perforation of the insulating body for the grounding contact is located, so that this grounding contact when inserting into its hole or hole in the plug is inserted, that the insertion of the contact spring fits through the lateral opening of the insulating body and at least one carries its outer side extending spring arm, which at a free, the male part projecting end has a radially inwardly extending, in the insertion path of the grounding contact projection, the grounding contact in the use position fixing be aufschlagt.
Auf diese Weise ist es möglich, die Haltefeder mit ihrem Einsteckteil von der Seite her in den Isolierkörper einzusetzen und danach den Erdungskontakt wie die übrigen Kontakte, seien es Stifte oder Buchsen, axial in seine Gebrauchsstellung zu verschieben und zu positionieren. Dabei durchsetzt der Er- dungskontakt automatisch den Einsteckteil und tritt mit diesem in Kontakt. Der Einsteckteil und die Haltefeder können also schon an dem Isolierkörper vorgesehen werden, bevor der Erdungskontakt montiert wird. Entsprechend einfach ist an- schließend die Montage dieses Erdungskontakts durch ein einfaches Einschieben in seine Lochung oder Bohrung und dabei auch in den Einsteckteil der Haltefeder. Gleichzeitig kann der Federarm mit seinem Vorsprung den Erdungskontakt fixieren, also festlegen, so dass eine einfache, auch schon bisher übliche Einsteckbewegungen für den Erdungskontakt ausreicht, um ihn zu montieren.In this way it is possible to use the retaining spring with its plug-in part from the side in the insulating body and then move the grounding contact as the other contacts, be it pins or sockets, axially in its position of use and position. The earthing contact automatically penetrates the plug-in part and comes in contact with it. The male part and the retaining spring can therefore already be provided on the insulating body before the grounding contact is mounted. It is accordingly easy to closing the mounting of this grounding contact by a simple insertion into its hole or hole and also in the insertion of the retaining spring. At the same time, the spring arm with its projection fix the grounding contact, so set, so that a simple, even previously usual insertion movements for the ground contact sufficient to mount it.
Ganz besonders zweckmäßig ist es dabei für eine einfache Mon- tage und Fixierung des Erdungskontakts, wenn der Erdungskontakt an der von dem Vorsprung des Federarms beaufschlagten Stelle eine Vertiefung hat und der Schwenkweg des Federarms wenigstens der Eingrifftiefe seines Vorsprungs in diese Vertiefung oder Ausnehmung entspricht. Beim Einschieben des Erdungskontakts in seine Lochung oder Bohrung wird also der Vorsprung des Federarms zunächst durch den eindringenden Erdungskontakt zur Seite gedrückt und dadurch der Federarm ausgelenkt, bis er in die Vertiefung hineinfedern und dadurch den Erdungskontakt fixieren kann. Somit entsteht beim Einschieben des Erdungskontakts automatisch eine Rast- oder Schnappbefestigung durch die elektrisch leitende Haltefeder.It is particularly expedient for a simple assembly and fixation of the grounding contact when the grounding contact on the acted upon by the projection of the spring arm has a recess and the pivoting of the spring arm corresponds to at least the depth of engagement of its projection in this recess or recess. When inserting the grounding contact in his hole or hole so the projection of the spring arm is first pressed by the penetrating ground contact to the side and thereby deflected the spring arm until it springs into the recess and thereby fix the grounding contact. Thus, when inserting the grounding contact automatically creates a snap or snap fastening by the electrically conductive retaining spring.
Der Federarm kann bei entspannter Feder mit seinem Vorsprung durch eine seitliche Öffnung des Isolierkörpers in das Innere der Öffnung oder Bohrung ragen und durch den einsteckbaren Erdungskontakt radial verschwenkbar sein. Wie erwähnt, kann also der Erdungskontakt bei seiner axialen Einsteckbewegungen auf diese Weise den zunächst teilweise in seinem Verschiebeweg befindlichen Vorsprung des Federarms seitlich beziehungsweise radial verdrängen und dadurch den Federarm verschwenken, bis die zum Einrasten des Vorsprungs des Federarms dienende Vertiefung im Bereich dieses Vorsprungs angekommen ist. Dabei kann die seitliche Öffnung für den Vorsprung des Federarms in axialer Richtung benachbart zu der seitlichen Öffnung für das Einführung des Einsteckteils in den Isolierkörper angeordnet sein. Somit wird der Isolierkörper nur so wenig wie notwendig mit seitlichen Öffnungen versehen beziehungsweise diese haben eine möglichst kleine Abmessung, die einerseits ausreicht, um den Einsteckteil durchzulassen, und wobei andererseits eine benachbarte Öffnung mit entsprechend geringer Abmessung den Durchtritt des Vorsprungs des Federarms in ra- dialer Richtung von außen nach innen in den Weg des Erdungskontakts ermöglicht. Außerdem stützt der zwischen den seitlichen Öffnungen befindliche Teil des Isolierkörpers den Federarm von innen ab, so dass er fest an der Innenseite der Hülse anliegen und erden kann.The spring arm can protrude with a relaxed spring with its projection through a lateral opening of the insulating body in the interior of the opening or bore and be radially pivotable through the pluggable grounding contact. As mentioned, therefore, the grounding contact in its axial insertion movements in this way, the first partially in its displacement projection of the spring arm displace laterally or radially, thereby pivoting the spring arm until the serving to engage the projection of the spring arm recess has arrived in the region of this projection , In this case, the lateral opening for the projection of the spring arm can be arranged in the axial direction adjacent to the lateral opening for the insertion of the male part in the insulating body. Thus, the insulator is provided as little as necessary with lateral openings or they have the smallest possible size, on the one hand sufficient to pass the male part, and on the other hand, an adjacent opening with a correspondingly small dimension, the passage of the projection of the spring arm in radial Direction from outside to inside in the path of the ground contact allows. In addition, the part of the insulating located between the side openings supports the spring arm from the inside, so that it can rest firmly against the inside of the sleeve and ground.
Besonders günstig ist es, wenn die Vertiefung an dem Erdungskontakt für den Eingriff des Vorsprungs des Federarms ringförmig umläuft und/oder in Einsteckrichtung durch einen umlaufenden Ring oder Bund begrenzt ist, der auf seiner der Vertiefung abgewandten Seite insbesondere sich verjüngend, konisch oder kegelstumpfförmig ausgebildet ist.It is particularly favorable if the depression on the ground contact for the engagement of the projection of the spring arm rotates annularly and / or is delimited in the plug-in direction by a circumferential ring or collar, which on its side facing away from the depression is in particular tapered, conical or frustoconical ,
Die Ringform der Vertiefung ermöglicht es, den Erdungskontakt, der in aller Regel einen kreisförmigen Querschnitt hat, in beliebiger Drehorientierung in seine Lochung oder Bohrung einzuführen und dennoch die Rast- oder Schnappverbindung mit dem zungenartigen Vorsprung des Federarms zu erlauben. Die sich verjüngende Form der Begrenzung der Vertiefung in Einsteckrichtung vor dieser Vertiefung erleichtert das seitliche Verdrängen des Federarms mit seinem Vorsprung.The ring shape of the recess makes it possible to introduce the grounding contact, which usually has a circular cross-section, in any rotational orientation in its hole or bore and still allow the snap or snap connection with the tongue-like projection of the spring arm. The tapered shape of the boundary of the recess in the insertion direction before this depression facilitates the lateral displacement of the spring arm with its projection.
Für eine möglichst präzise Positionierung des Erdungskontakts kann es vorteilhaft sein, wenn der Vorsprung des Federarmes an seinem freien Ende eine insbesondere in axialer Richtung orientierte Haltezunge oder Verbreiterung aufweist, womit die Vertiefung ausgefüllt oder ein Anschlag zu einer der Begrenzungen der Vertiefung hergestellt werden kann, wenn der Er- dungskontakt seine genaue axiale Lage erreicht hat.For a precise positioning of the grounding contact, it may be advantageous if the projection of the spring arm on its free end has a particular oriented in the axial direction retaining tongue or broadening, whereby the recess can be filled or a stop can be made to one of the boundaries of the recess when the Erd dungskontakt has reached its exact axial position.
Besonders günstig ist es, wenn der Emsteckteil der Haltefeder eine größere seitliche Abmessung als die seitliche Öffnung des Isolierkörpers hat und etwa der seitlichen Abmessung oder dem Durchmesser der Lochung oder Bohrung für den Erdungskontakt entspricht, und wenn der Emsteckteil quer zu seiner Innenlängshöhlung beziehungsweise in radialer Richtung gegen seine Elastizität soweit zusammendrückbar ist, dass er durch die seitliche Öffnung einführbar ist, die außerdem etwas konisch sein kann. Der Emsteckteil kann also durch eine seitliche Öffnung des Isolierkörpers in seine Gebrauchslage gebracht werden und dann aufgrund seiner Eigenelastizität die Ränder der seitlichen Öffnung hintergreifen, so dass er unverlierbar und weitgehend formschlüssig gehalten wird. In vorteilhafter Weise kann somit die Haltefeder vormontiert sein, so dass anschließend nur noch der Erdungskontakt eingeschoben und verrastet werden muss, um die Montage zu beenden.It when the Emsteckteil the retaining spring has a larger lateral dimension than the lateral opening of the insulating and corresponds approximately to the lateral dimension or the diameter of the hole or hole for the ground contact, and if the Emsteckteil transverse to its inner longitudinal cavity or in the radial direction is particularly favorable against its elasticity is compressible so far that it can be inserted through the side opening, which may also be slightly conical. The Emsteckteil can thus be brought by a lateral opening of the insulating in its position of use and then engage behind the edges of the lateral opening due to its inherent elasticity, so that it is held captive and largely positive fit. Advantageously, thus, the retaining spring can be pre-assembled, so that subsequently only the grounding contact has to be inserted and locked in order to finish the assembly.
Dabei ist es günstig, dass der Emsteckteil m Gebrauchsstel- lung durch den ihn insbesondere formschlüssig durchsetzenden Erdungskontakt gegen eine radiale Zusammendrückung gesichert oder gesperrt ist. Befindet sich der Erdungskontakt m Gebrauchsstellung kann also die Haltefeder nicht mehr aus der seitlichen Öffnung des Isolierkörpers herausgezogen werden. Gleichzeitig verläuft aber der Federarm an diese Außenseite außerhalb der seitlichen Öffnung und kann in Kontakt mit der den Isolierkörper aufnehmenden Hülse treten, um die gewünschte Erdung herbeizuführen. Zweckmäßig ist es, wenn der Einsteckteil der Haltefeder als Hülse ausgebildet ist, die den Erdungskontakt in Gebrauchsstellung außenseitig zumindest bereichsweise flächig berührt. Eine entsprechend große Kontaktfläche zwischen Haltefeder und Erdungskontakt steht auf diese Weise zur Verfügung. Dabei kann die elektrisch leitende Haltefeder aus wenigstens bereichsweise elektrischen Strom leitendem Werkstoff, insbesondere aus Metall bestehen.In this case, it is favorable that the emplacement part is secured or blocked against radial compression by the grounding contact passing through it, in particular in a form-locking manner. Is the ground contact m use position so the retaining spring can not be pulled out of the lateral opening of the insulator. At the same time, however, the spring arm extends to this outer side outside the lateral opening and can come into contact with the insulating body receiving sleeve to bring about the desired grounding. It is expedient if the insertion part of the retaining spring is designed as a sleeve, which touches the grounding contact in the position of use on the outside at least partially flat. A correspondingly large contact surface between the retaining spring and grounding contact is available in this way. In this case, the electrically conductive retaining spring of at least partially electrical current conductive material, in particular made of metal.
Ferner ist es günstig, wenn der hülsenförmige Einsteckteil wenigstens einen etwa in axialer Richtung verlaufenden, insbesondere durchgehenden Schlitz oder dergleichen Unterbrechung hat und in entspanntem Zustand einen geringeren Querschnitt als der Erdungskontakt hat. Dieser weitet dann bei seinem Einführen in seine Gebrauchslage den Einsteckteil auf, so dass dieser durch die dabei auftretenden Rückstellkräfte gut an dem Erdungskontakt angedrückt wird und zu einem entsprechend sicheren elektrischen Kontakt führt.Further, it is advantageous if the sleeve-shaped insertion part has at least one extending approximately in the axial direction, in particular continuous slot or the like interruption and in the relaxed state has a smaller cross-section than the ground contact. This expands when inserted into its position of use the male part, so that it is pressed well by the restoring forces occurring at the ground contact and leads to a correspondingly secure electrical contact.
Der Federarm kann an dem in Einsteckrichtung vorderen Ende der Haltefeder und ihres Emsteckteils insbesondere einstückig angebracht und sich in Einsteckrichtung erstreckend angeordnet sein. Dadurch verläuft dieser Federarm über eine größtmögliche Länge der Haltefeder und kann einen guten Kontakt zu der Hülse des Steckers herstellen. Darüber hinaus tritt bei dem axialen Einführen des Erdungskontakts und dessen Beaufschlagung des Vorsprungs des Federarms neben der radialen Verschwenkung auch eine gewisse axiale Belastung auf, die bei der erwähnten Anordnung als Zugkraft auf den Federarm wirkt und deshalb nicht zu dessen Stauchung führen kann.The spring arm can in particular be integrally attached to the front end of the retaining spring and its Emsteckteils in the insertion direction and arranged extending in the insertion direction. As a result, this spring arm extends over a maximum length of the retaining spring and can make good contact with the sleeve of the plug. In addition occurs in the axial insertion of the ground contact and its application to the projection of the spring arm in addition to the radial pivoting on a certain axial load, which acts in the above arrangement as a tensile force on the spring arm and therefore can not lead to its compression.
Besonders preiswert ist die Haltefeder, wenn sie mit ihrem Einsteckteil und mit ihrem Federarm insbesondere einstückig aus einem Teil oder Stanzteil gebogen ist. Ein etwas breiterer Teil eines solchen Stanzteils kann zu einer Hülse gerollt werden, während ein von diesem breiteren Teil abgehender schmaler Teil den Federarm bilden kann, an dessen freies Ende der erwähnte Vorsprung gegebenenfalls mit zusätzlicher Haltezunge oder dergleichen Verbreiterung angeformt werden kann.Particularly inexpensive is the retaining spring when with her Insertion and in particular with its spring arm is integrally bent from a part or stamped part. A slightly wider part of such a stamped part can be rolled into a sleeve, while a narrow part extending from this wider part can form the spring arm, at the free end of which the aforementioned projection can optionally be formed with additional retaining tongue or the like widening.
Es sei noch erwähnt, dass der Federarm der Haltefeder eine in Querrichtung seiner Erstreckung verlaufende Verbreiterung aufweisen kann, um die Kontaktfläche zu der Innenseite der Strom leitenden Hülse des Steckers zu vergrößern.It should be noted that the spring arm of the retaining spring may have a widening extending in the transverse direction of its extension broadening to increase the contact area to the inside of the current-conducting sleeve of the plug.
Vor allem bei Kombination einzelner oder mehrerer der vorbe- schriebenen Merkmale und Maßnahmen ergibt sich ein Stecker mit Isolierkörper, Erdungskontakt und diesen Erdungskontakt erfassender und festlegender Haltefeder, der durch einfache Steckbewegungen montiert werden kann, wobei dennoch der Erdungskontakt gut fixiert, kontaktiert und positioniert werden kann, weil die Haltefeder nicht nur den elektrischen Kontakt herstellt, sondern mit Hilfe eines Federarms auch die Fixierung und Befestigung des Erdungskontakts bewirkt, wobei dieser Federarm eine Doppelfunktion hat, weil er neben dieser Fixierung des Erdungskontakts auch den Kontakt zu der Hülse des Steckers herstellt. Dieser Federarm ist also gleichzeitig eine Erdungsfeder .Especially when combining one or more of the above-described features and measures results in a plug with insulating body, grounding contact and this ground contact detecting and festive retaining spring, which can be mounted by simple insertion movements, yet the grounding contact can be well fixed, contacted and positioned because the retaining spring not only makes the electrical contact, but also causes the fixing and attachment of the grounding contact with the aid of a spring arm, this spring arm has a dual function, because he also makes contact with the sleeve of the plug in addition to this fixation of the grounding contact. This spring arm is thus at the same time a grounding spring.
Eine relativ einfache Herstellung der Teile einerseits und eine effektive Kontaktierung andererseits ergibt sich, wenn der als Erdungsfeder dienende Federarm einen flachen ebenen, also geradlinig begrenzten Querschnitt hat und in Gebrauchsstellung in der im Querschnitt kreisbogenförmigen Fuge zwischen der im Querschnitt kreisförmigen Innenseite der Hülse und der Außenseite des Isolierkörpers eingeklemmt ist. Da der Querschnitt des Federarms nicht genau zu dem der Fuge passt, wird er an den jeweiligen Berührstellen entsprechend stark angedrückt und möglicherweise auch noch etwas verformt, was zu entsprechend guten elektrischen Kontakten führt.A relatively simple manufacture of the parts on the one hand and an effective contact on the other hand results when the spring arm serving as a grounding arm has a flat, so rectilinear limited cross-section and in the use position in the cross-sectional arcuate joint between the circular in cross-section inside the sleeve and the Outside of the insulating body is clamped. Since the cross section of the spring arm does not exactly match that of the joint, it is correspondingly strongly pressed at the respective contact points and possibly also somewhat deformed, which leads to correspondingly good electrical contacts.
Nachstehend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben. Es zeigt in zum Teil schematisierter Darstellung:An embodiment of the invention will be described in more detail below with reference to the drawing. It shows in partly schematized representation:

Der in Fig.2 in seinem Endzustand und in Fig.1 in Einzelteilen dargestellte Stecker 1 weist eine sein Gehäuse bildende Hülse 2 und einen in Gebrauchsstellung im Inneren dieser Hülse 2 angeordneten und fixierten Isolierkörper 3 sowie längliche stiftartige Kontakte 4 auf, die Kontaktstifte oder Kontaktbuchsen sein können, bei welchen also der Gegenstecker dann Stifte aufweist. An diese Kontakte 4 werden in üblicher Weise vor oder nach der Montage Kabel oder Litzen angeschlossen, zum Beispiel angelötet .The illustrated in Figure 2 in its final state and in Figure 1 in parts connector 1 has a housing forming its sleeve 2 and a in use position inside this sleeve 2 arranged and fixed insulating body 3 and elongated pin-like contacts 4, the contact pins or contact sockets may be, in which therefore the mating connector then has pins. At these contacts 4 cables or wires are connected in the usual way before or after assembly, for example, soldered.
Der Isolierkörper 3 enthält Lochungen oder Bohrungen 6, in welchen die Kontakte 4 fixiert werden, wobei ein Kontakt als Erdungskontakt 5 parallel zu den übrigen Kontakten 4 innerhalb einer dieser Lochungen oder Bohrungen 6 angeordnet ist, welche eine seitliche Öffnung 8 für eine elektrisch leitende, im Ganzen mit 9 bezeichnete Haltefeder aufweist, die den Erdungskontakt 5 in Gebrauchsstellung in seiner Lochung oder Bohrung 6 festlegt.The insulating body 3 contains holes or holes 6, in which the contacts 4 are fixed, wherein a contact is arranged as a grounding contact 5 parallel to the other contacts 4 within one of these holes or holes 6, which has a lateral opening 8 for an electrically conductive, in the Whole designated 9 retaining spring which defines the grounding contact 5 in the use position in its perforation or hole 6.
Vor allem in den Figuren 1, 6 und 8, aber auch in den Fig.4 und 5 erkennt man, dass die Haltefeder 9 einen in axialer Richtung durchgängigen, in Gebrauchsstellung innerhalb der Lochung oderEspecially in Figures 1, 6 and 8, but also in Figures 4 and 5 it can be seen that the retaining spring 9 a continuous in the axial direction, in the position of use within the perforation or
Bohrung 6 des Isolierkörpers 3 angeordneten Einsteckteil 10 hat, dessen lichter Innenquerschnitt gemäß Fig.3 bis 5 etwa demBore 6 of the insulating body 3 arranged plug-in part 10 has its inner light section according to Figure 3 to 5 about the
Außenquerschnitt des im wesentlichen stiftförmigen oder hülsenförmigen Erdungskontakts 5 entspricht und der sich inOuter cross-section of the substantially pin-shaped or sleeve-shaped grounding contact 5 corresponds and in
Gebrauchsstellung innerhalb des Isolierkörpers 3 in Flucht und koaxial zu der Öffnung oder Lochung 6 des Isolierkörpers 3 für den Erdungskontakt 5 befindet. Der Erdungskontakt 5 ist also beim axialen Einführen in seine Lochung oder Bohrung 6 gleichzeitig in diesen zuvor montierten Einsteckteil 10 einschiebbar und einsteckbar.Use position within the insulating body 3 in alignment and coaxial with the opening or perforation 6 of the insulating body 3 for the ground contact 5 is located. The grounding contact 5 is thus at the same time inserted into its hole or hole 6 during axial insertion into this previously mounted plug 10 and inserted.
Dabei passt dieser Einsteckteil 10 der Haltefeder 9 durch die seitliche Öffnung 8 des Isolierkörpers 3, kann also von der Seite her durch diese Öffnung 8 in seine Gebrauchslage gebracht werden. In Fig.1 ist die Haltefeder 9 und ihr Einsteckteil 10 noch vor dieser Montage erkennbar, während Fig. 3 und 4 die Gebrauchslage der Haltefeder 9 und ihres Einsteckteils 10 zeigen. Dabei erkennt man in den Fig.3 und 4 auch, dass die seitliche Öffnung 8 leicht konisch mit einem sich zur Mitte des Isolierkörpers 3 etwas verringernden Querschnitt ausgebildet ist, was das Einführen des Einsteckteils 10 erleichtert.In this case, this insertion part 10 of the retaining spring 9 fits through the lateral opening 8 of the insulating body 3, so it can be brought from the side through this opening 8 in its position of use. In Figure 1, the retaining spring 9 and its male part 10 is still recognizable before this assembly, while Fig. 3 and 4, the position of use of the retaining spring 9 and its male part of the 10th demonstrate. It can be seen in Figures 3 and 4 also that the lateral opening 8 is slightly conical with a to the center of the insulating body 3 slightly reducing cross section is formed, which facilitates the insertion of the male part 10.
Vor allem in den Fig.1 , 6 und 8 sowie auch in Fig.4 und 5 erkennt man außerdem, dass der Einsteckteil 10 einen an seiner Außenseite verlaufenden Federarm 11 trägt, der an seinem freien, den Einsteckteil 10 überragenden Ende einen radial nach innen gerichteten, in den Einsteckweg des Erdungskontakts 5 reichenden Vorsprung 12 hat, der den Erdungskontakt 5 in Gebrauchsstellung in noch zu beschreibender Weise fixierend und in axialer Richtung festlegend beaufschlagt.Especially in FIGS. 1, 6 and 8 as well as in FIGS. 4 and 5, it can also be seen that the plug-in part 10 carries a spring arm 11 extending on its outside, which at its free end projecting beyond the plug-in part 10 projects radially inwards directed, in the insertion of the grounding contact 5-reaching projection 12 which has the grounding contact 5 in the position of use in still-to-be-described way fixed and applied in the axial direction.
Vor allem in Fig.1 ist dargestellt, dass der Erdungskontakt 5 an der von dem Vorsprung 12 des Federarms 11 in Gebrauchs- Stellung beaufschlagten Stelle eine Vertiefung 7 hat und der Schwenkweg des Federarms 11 wenigstens der Eingrifftiefe seines Vorsprungs 12 in diese Ausnehmung oder Vertiefung 7 entspricht.In particular, it is shown in FIG. 1 that the earthing contact 5 has a recess 7 on the point acted upon by the projection 12 of the spring arm 11 and the pivoting path of the spring arm 11 is at least the engagement depth of its projection 12 into this recess or recess 7 equivalent.
Gemäß Fig.5 ragt der Vorsprung 12 des Federarms 11 bei entspannter Lage oder entspannter Feder durch eine seitliche Öffnung 13 des Isolierkörpers 3 in das Innere der Öffnung oder Bohrung 6 und ist durch den einsteckbaren Erdungskontakt 5 radial verschwenkbar. Dabei ist die seitliche Öffnung 13 für den Vorsprung 12 des Federarms 11 in axialer Richtung benachbart zu der seitlichen Öffnung 8 für das Einführen des Einsteckteils 10 in den Isolierkörper 3 angeordnet, wobei die beiden Öffnungen 8 und 13 des Abmessungen und Abständen des Einsteckteils 10 und des Vorsprungs 12 voneinander entsprechen.According to Figure 5 protrudes the projection 12 of the spring arm 11 in a relaxed position or relaxed spring through a lateral opening 13 of the insulating body 3 in the interior of the opening or bore 6 and is radially pivotable through the plug-in grounding contact 5. In this case, the lateral opening 13 is arranged for the projection 12 of the spring arm 11 in the axial direction adjacent to the lateral opening 8 for the insertion of the male part 10 in the insulating body 3, wherein the two openings 8 and 13 of the dimensions and distances of the male part 10 and Projection 12 correspond to each other.
In Fig.1 erkannt man, dass die Vertiefung 7 an den Erdungskontakt 5, die für den Eingriff des Vorsprungs 12 des Federarms 11 vorgesehen ist, ringförmig umläuft, also als Ringnut ausgebildet ist und somit eine beliebige Dreh-Position des Erdungskontakts 5 bei seiner Montage erlaubt.In Fig.1 it is recognized that the recess 7 to the grounding contact 5, which is responsible for the engagement of the projection 12 of the spring arm 11 is provided, annularly rotates, that is designed as an annular groove and thus allows any rotational position of the grounding contact 5 during its assembly.
Dabei erkennt man ferner, dass die ringnutartige Vertiefung 7 durch einen umlaufenden Ring oder Bund 14 begrenzt ist, der auf seiner der Vertiefung 7 abgewandten und in Einsteckrichtung vorderen Seite 14a sich verjüngend, konisch oder kegelstumpfförmig ausgebildet ist, um beim Einschieben des Er- dungskontakts 5 das Beaufschlagen und radiale Verschwenken des Vorsprungs 12 des Federarms 11 zu erleichtern.It can also be seen that the annular groove-like recess 7 is bounded by a circumferential ring or collar 14, which is tapered, conical or frusto-conical on its side facing away from the recess 7 and 14a in the insertion direction to the insertion contact to facilitate the application and radial pivoting of the projection 12 of the spring arm 11.
Für eine gute axiale Positionierung ist vorgesehen, dass der Vorsprung 12 des Federarms 11 an seinem freien Ende eine in axialer Richtung orientierte Haltezunge 15 hat, die gemäß Fig.5 in Gebrauchsstellung an der als Bund 14 ausgebildeten Begrenzung der Nut 7 anschlägt .For a good axial positioning is provided that the projection 12 of the spring arm 11 at its free end has an axially oriented retaining tab 15 which abuts according to Figure 5 in the use position on the designed as a collar 14 boundary of the groove 7.
Vor allem anhand der Fig.3 und 4 wird deutlich, dass der Einsteckteil 10 der Haltefeder 9 eine größere seitliche oder radiale Abmessung als die seitliche Öffnung 8 des Isolierkörpers 3 hat und dabei etwa der seitlichen Abmessung oder dem Durchmesser der Lochung oder Bohrung 6 für den Erdungskontakt 5 entspricht, so dass der Einsteckteil 10 in Gebrauchsstellung diese Bohrung 6 praktisch mit seiner Außenseite ausfüllt. Gleichzeitig ist der Einsteckteil 10 quer zu seiner Innenlängshöhlung beziehungsweise in radialer Richtung gegen die Elastizität seines Werkstoffs soweit zusammendrückbar, dass er durch die seitliche Öffnung 8 einführbar ist. Dabei kann diese seitliche oder radiale Zusammendrückung durch die etwas konische Form der seitlichen Öffnung 8 unterstützt werden. Der Benutzer kann also die Haltefeder 9 und dabei vor allem deren Einsteckteil 10 in die seitliche Öffnung 8 einführen und die Haltefeder 9 parallel zu sich selbst durch die Öffnung 8 hindurchdrücken, wobei der Einsteckteil 10 zunächst etwas nachgibt, um dann im Inneren der Lochung oder Bohrung 6 wieder seine ursprüngliche Form einzunehmen. Dadurch gelangt also der Einsteckteil 10 in eine Art Hinterschneidung und ist formschlüssig und damit unverlierbar gehalten. Somit ist der Einsteckteil 10 in Gebrauchsstellung durch den ihn formschlüssig durchsetzenden Erdungskontakt 5 gegen eine radiale Zusammendrückung gesichert oder gesperrt und dadurch halten sich also die beiden Teile, nämlich der Erdungskontakt 5 und die Haltefeder 9 gegenseitig fest in ihrer Gebrauchsstellung.Especially with reference to Figures 3 and 4 it is clear that the male part 10 of the retaining spring 9 has a larger lateral or radial dimension than the lateral opening 8 of the insulator 3 and about the lateral dimension or the diameter of the hole or hole 6 for the Earthing contact 5 corresponds, so that the plug 10 in the position of use, this hole 6 practically fills with its outside. At the same time, the male part 10 is compressible transversely to its inner longitudinal cavity or in the radial direction against the elasticity of its material so far that it can be inserted through the lateral opening 8. In this case, this lateral or radial compression can be supported by the slightly conical shape of the lateral opening 8. The user can thus insert the retaining spring 9 and in particular its plug 10 in the lateral opening 8 and the Holding spring 9 parallel to push itself through the opening 8, wherein the male member 10 first yields slightly, then to take its original shape inside the hole or hole 6 again. As a result, the male member 10 thus enters a kind of undercut and is held in a form-fitting manner and thus captive. Thus, the male member 10 is secured in the position of use by the form-fitting passing through ground contact 5 against radial compression or locked and thus hold so the two parts, namely the ground contact 5 and the retaining spring 9 mutually fixed in their position of use.
Der Einsteckteil 10 der Haltefeder 9 ist dabei als Hülse aus- gebildet, die den Erdungskontakt 5 in Gebrauchsstellung außenseitig zumindest bereichsweise flächig berührt, was einen guten elektrischen Kontakt ergibt, der aber auch noch durch den Vorsprung 12 des Federarms 11 und dessen Haltezunge 15 unterstützt wird, so dass in jedem Falle ein guter elektrischer Kontakt zwischen Erdungskontakt 5 und Haltefeder 9 besteht, selbst wenn in dem einen oder anderen Bereich Zwischenräume auftreten sollten.The plug-in part 10 of the retaining spring 9 is formed as a sleeve, which touches the ground contact 5 in the use position outside at least partially flat, which gives a good electrical contact, but also supported by the projection 12 of the spring arm 11 and the retaining tongue 15 , so that in each case there is a good electrical contact between grounding contact 5 and retaining spring 9, even if in one or the other area gaps should occur.
Der in Fig.4 erkennbare Abstand zwischen Einsteckteil 10 und Erdungskontakt 5 ist gemäß Fig.5 nur über einen Teil der Länge dieses Erdungskontakts 5 vorgesehen.The recognizable in Figure 4 distance between plug 10 and grounding contact 5 is provided in accordance with Figure 5 only over part of the length of this grounding contact 5.
Gemäß Fig.4, 6 und 8 hat der hülsenförmige Einsteckteil 10 einen etwa in axialer Richtung verlaufenden Schlitz 16 oder dergleichen Unterbrechung und kann in entspanntem Zustand einen geringeren Querschnitt als der Erdungskontakt 5 haben, so dass dieser beim Einschieben den hülsenförmigen Einsteckteil 10 etwas aufweiten kann, um den Kontakt zu verbessern. Die elektrisch leitende Haltefeder 9 besteht nämlich aus wenigstens bereichsweise elektrischen Strom leitendem Werkstoff, insbesondere aus Metall. Dabei wird vor allem in den Fig.1, 5 und 6 bis 9 deutlich, dass der Federarm 11 an dem in Einsteckrichtung des Erdungskontakts 5 vorderen Ende 1 Oa des Einsteckteils 10 und der Haltefeder 9 einstückig angebracht und sich in Einsteckrichtung erstreckend angeordnet ist. Beim Einschieben des Erdungskontakts 5 kommt dieser also zunächst mit dem Ende 10a der Haltefeder 9 in Berührung, von welchem sich der Federarm 11 in Richtung der weiteren Einsteckbewegung erstreckt. Dadurch wird erreicht, dass beim Beaufschlagen des Vorsprungs 12 des Federarms 11 mit dem Vorsprung oder Bund 14 des Erdungskontakts 5 der Federarm 11 nicht nur radial seitlich nach außen ausgelenkt, sondern auch einer gewissen Zugkraft unterworfen wird, so dass keine Gefahr besteht, dass dieser Federarm 11 gestaucht wird.According to Fig.4, 6 and 8, the sleeve-shaped plug 10 has a running approximately in the axial direction slot 16 or the like interruption and may have a smaller cross-section than the ground contact 5 in the relaxed state, so that it can expand the sleeve-shaped plug 10 slightly when inserted to improve the contact. The electrically conductive retaining spring 9 consists namely of at least partially electrical current conductive material, in particular of metal. 1, 5 and 6 to 9 that the spring arm 11 is integrally attached to the front end 1 Oa of the male member 10 and the retaining spring 9 in the insertion direction of the earth contact 5 and is arranged to extend in the insertion direction. When inserting the grounding contact 5 so this comes first with the end 10a of the retaining spring 9 into contact, of which the spring arm 11 extends in the direction of further insertion movement. It is thereby achieved that upon application of the projection 12 of the spring arm 11 with the projection or collar 14 of the earthing contact 5, the spring arm 11 is not only radially deflected laterally outward, but also subjected to a certain tensile force, so that there is no danger that this spring arm 11 is compressed.
Die Haltefeder 9 ist dabei mit ihrem Einsteckteil 10 und mit ihrem Federarm 11 einstückig aus einem Teil, bevorzugt aus einem Stanzteil gebogen. Entsprechende Stanzteile sind in den Fig.7 und 9 dargestellt und man erkennt deutlich einen breiteren Bereich, der den Einsteckteil 10 bilden wird und von welchem der Federarm 11 abgeht .The retaining spring 9 is in this case with its plug 10 and with its spring arm 11 in one piece from a part, preferably bent from a stamped part. Corresponding stamped parts are shown in FIGS. 7 and 9, and it is clearly possible to see a wider region which will form the plug-in part 10 and from which the spring arm 11 leaves.
Dabei zeigen die Fig.8 und 9, dass der Federarm 11 der Haltefeder 9 eine in Querrichtung seiner Erstreckung verlaufende Verbreiterung 17 aufweisen kann, die den Kontakt zu der Innenseite der elektrisch leitenden Hülse 2 vergrößern kann.8 and 9 show that the spring arm 11 of the retaining spring 9 can have a widening 17 extending in the transverse direction of its extension, which can increase the contact with the inside of the electrically conductive sleeve 2.
Gemäß den Fig.4, 7 und 9 hat der als Erdungsfeder dienende Federarm 11 einen flachen ebenen Querschnitt und ist in Gebrauchsstellung in der im Querschnitt kreisbogenförmigen Fuge 18 zwischen der im Querschnitt kreisförmigen Innenseite der Hülse 2 und der Außenseite des Isolierkörpers 3 eingeklemmt, was eine entsprechend gute Kontaktierung ergibt.4, 7 and 9 serving as grounding spring arm 11 has a flat planar cross-section and is in the use position in the circular arc-shaped joint 18 clamped between the circular in cross-section inside the sleeve 2 and the outside of the insulating body 3, resulting in a correspondingly good contact.
