Description

Die vorliegende Erfindung betrifft ein elektrisches Anschlusselement mit einem Buchsenabschnitt zur Aufnahme eines Steckkontakts, wobei der Buchsenabschnitt zwei Kontaktfederarme zur Kontaktierung des in dem Buchsenabschnitt aufgenommenen Steckkontakts und eine nach außen umgebogene Verriegelungszunge zur Verriegelung des Anschlusselements in einem Gehäuse umfasst.The present invention relates to an electrical connection element with a socket portion for receiving a plug-in contact, wherein the socket portion comprises two contact spring arms for contacting the plug-in contact received in the socket portion and an outwardly bent locking tongue for locking the connection element in a housing.

Der Buchsenabschnitt eines bekannten Anschlusselements der eingangs genannten Art ist durch ein die Kontaktfederarme aufweisendes Grundteil und eine separate Überfeder gebildet, die das Grundteil umgibt. Die Überfeder definiert die äußere Geometrie des Buchsenabschnitts und ist mit der Verriegelungszunge versehen. Aufgrund der zweiteiligen Ausbildung ist die Herstellung des bekannten Anschlusselements mit einem erhöhten wirtschaftlichen Aufwand verbunden.The female portion of a known connection element of the type mentioned is formed by a contact spring arms exhibiting base and a separate over-spring, which surrounds the base. The over-spring defines the outer geometry of the female portion and is provided with the locking tongue. Due to the two-part design, the production of the known connection element is associated with an increased economic outlay.

Der Erfindung liegt die Aufgabe zugrunde, ein elektrisches Anschlusselement zu schaffen, welches mit einem geringeren wirtschaftlichen Aufwand herstellbar ist.The invention has for its object to provide an electrical connection element which can be produced with a lower economic cost.

Die Aufgabe wird erfindungsgemäß durch ein elektrisches Anschlusselement mit den Merkmalen des Anspruchs 1 und insbesondere dadurch gelöst, dass der Buchsenabschnitt einstückig ausgebildet ist.The object is achieved by an electrical connection element with the features of claim 1 and in particular in that the bushing portion is integrally formed.

Durch die einstückige Ausbildung des Buchsenabschnitts, mit anderen Worten also der Kontaktfederarme und der Verriegelungszunge, wird im Vergleich zu dem bekannten Anschlusselement nicht nur der Materialeintrag, d.h. also die zur Herstellung des Anschlusselements erforderliche Materialmenge, minimiert, sondern auch eine höhere Fertigungsgeschwindigkeit erreicht, da erfindungsgemäß keine separate Überfeder an einem Grundteil des Buchsenabschnitts angebracht zu werden braucht. Insgesamt lässt sich das erfindungsgemäße Anschlusselement also kostengünstiger herstellen.Due to the one-piece design of the socket portion, in other words the contact spring arms and the locking tongue, not only the material input, i. Thus, the amount of material required for the preparation of the connection element, minimized, but also achieved a higher production rate, since according to the invention no separate over-spring needs to be attached to a base of the female section. Overall, the connection element according to the invention can therefore be produced more cheaply.

Bei dem erfindungsgemäßen Anschlusselement handelt es sich bevorzugt um ein Stanz/Biegeteil, welches durch ein geeignetes Umbiegen einer entsprechenden Stanzplatine in eine Form derart gebracht wird, dass die äußere Geometrie des Buchsenabschnitts mit der äußeren Gestalt des zweiteiligen Buchsenabschnitts eines herkömmlichen Anschlusselements im Wesentlichen übereinstimmt. Das erfindungsgemäße Anschlusselement kann somit anstelle eines herkömmlichen Anschlusselements in ein bereits bestehendes Gehäuse eingesetzt und in diesem verriegelt werden.The connecting element according to the invention is preferably a stamped / bent part, which is brought into a shape such that the outer geometry of the bushing section substantially matches the outer shape of the two-part bushing section of a conventional connecting element by suitably bending a corresponding stamping plate. The connecting element according to the invention can thus be used instead of a conventional connecting element in an existing housing and locked in this.

Vorteilhafte Ausbildungen der Erfindung sind den Unteransprüchen, der Beschreibung und der Zeichnung zu entnehmen.Advantageous embodiments of the invention are described in the dependent claims, the description and the drawings.

Gemäß einer Ausführungsform gehen die Kontaktfederarme in einem einer Einführöffnung für den Steckkontakt abgewandten Bereich des Buchsenabschnitts aus gegenüberliegenden Wandsegmenten des Buchsenabschnitts hervor. Die Kontaktfederarme sind also im Bereich ihrer - in Steckrichtung gesehen - hinteren Enden angelenkt, während ihre vorderen, im Bereich der Einführöffnung gelegenen freien Enden beim Einführen des Steckkontakts in den Buchsenabschnitt ein Auseinanderdrücken der Kontaktfederarme ermöglichen.According to one embodiment, the contact spring arms project from opposite wall segments of the socket section in a region of the socket section facing away from an insertion opening for the plug contact. The contact spring arms are thus in the range of their - seen in the insertion direction - hinged rear ends, while their front, located in the region of the insertion opening free ends during insertion of the plug contact in the socket portion allow a squeezing of the contact spring arms.

Die Verriegelungszunge kann aus einem im Bereich einer Einführöffnung für den Steckkontakt gelegenen Wandsegment des Buchsenabschnitts hervorgehen und zumindest im Bereich eines der Einführöffnung abgewandten freien Endes nach außen umgebogen sein. Die Verriegelungszunge ist mit anderen Worten im Bereich ihres vorderen Endes angelenkt und im Bereich ihres hinteren Endes nach außen umgebogen. Auf diese Weise kann die Verriegelungszunge mit einem in einem Gehäuse für das Anschlusselement vorgesehenen Rastvorsprung zusammenwirken und verhindern, dass das Anschlusselement beim Einführen eines Steckkontakts in den Buchsenabschnitt aus dem Gehäuse herausgeschoben wird.The locking tongue can emerge from a wall segment of the socket section located in the region of an insertion opening for the plug-in contact and can be bent outward at least in the region of a free end facing away from the insertion opening. The locking tongue is articulated in other words in the region of its front end and bent in the region of its rear end to the outside. In this way, the locking tongue can cooperate with a latching projection provided in a housing for the connection element and prevent the connection element from being pushed out of the housing when a plug contact is inserted into the socket section.

Vorteilhafterweise verläuft die Verriegelungszunge außerhalb des einen Kontaktfederarms, d.h. sie ist auf der dem anderen Kontaktfederarm abgewandten Seite des einen Kontaktfederarms angeordnet.Advantageously, the locking tongue extends outside of one contact spring arm, i. it is arranged on the side facing away from the other contact spring arm of a Kontaktfederarms.

Gemäß einer weiteren Ausführungsform ist für wenigstens einen der Kontaktfederarme ein Überbiegeschutz vorgesehen. Bevorzugt ist für jeden der Kontaktfederarme ein derartiger Überbiegeschutz vorgesehen. Der Überbiegeschutz verhindert, dass die Kontaktfederarme z.B. bei einem unsachgemäßen Einführen des Steckkontakts in den Buchsenabschnitt über Gebühr nach außen umgebogen und dadurch beschädigt werden können. Der Überbiegeschutz trägt folglich zu einer dauerhaft zuverlässigen Funktion der Kontaktfederarme und somit des Anschlusselements insgesamt bei.According to a further embodiment, overbending protection is provided for at least one of the contact spring arms. Preferably, such overbending protection is provided for each of the contact spring arms. The overbias protection prevents the contact spring arms from e.g. if the plug-in contact is improperly inserted into the socket section, it can be excessively bent outwards and thereby damaged. The overbending protection thus contributes to a permanently reliable function of the contact spring arms and thus of the connection element as a whole.

Bevorzugt weist ein Kontaktfederarm einen seitlichen Vorsprung auf, der in eine in einem Wandsegment des Buchsenabschnitts vorgesehene Öffnung eingreift. Der in die Öffnung eingreifende Vorsprung stellt eine besonders einfache und wirkungsvolle Form eines Überbiegeschutzes für den Kontaktfederarm dar. Darüber hinaus kann der in die Öffnung eingreifende Vorsprung eine Verriegelung für den Buchsenabschnitt bilden und ein "Auseinanderfalten" des Buchsenabschnitts verhindern.A contact spring arm preferably has a lateral projection which engages in an opening provided in a wall segment of the socket section. The engaging in the opening projection provides a particularly simple and effective form of Überbiegeschutzes for In addition, the protrusion engaging the opening may form a latch for the bushing portion and prevent "unfolding" of the bushing portion.

Eine weitere einfache Form eines Überbiegeschutzes liegt vor, wenn aus wenigstens einem Seitenwandsegment des Buchsenabschnitts eine Schutzlasche hervorgeht, die so umgebogen ist, dass sie einen Kontaktfederarm zumindest teilweise überragt.Another simple form of overbend protection is when from at least one side wall segment of the female portion a protective tab emerges, which is bent so that it projects beyond a contact spring arm at least partially.

Grundsätzlich ist es möglich, den Buchsenabschnitt so zu gestalten, dass beide Kontaktfederarme durch aus Seitenwandsegmenten des Buchsenabschnitts hervorgehende und die Kontaktfederarme zumindest teilweise überragende Schutzlaschen geschützt sind oder dass beide Kontaktfederarme jeweils einen seitlichen Vorsprung aufweisen, der in eine entsprechende Öffnung in einem Wandsegment des Buchsenabschnitts eingreift.In principle, it is possible to design the bushing section such that both contact spring arms are protected by protective tabs protruding from side wall segments of the bushing section and at least partially overhanging the contact spring arms or both contact spring arms each have a lateral projection which engages in a corresponding opening in a wall segment of the bushing section ,

Gemäß einer besonders bevorzugten Ausführungsform weist jedoch der eine Kontaktfederarm einen in eine Wandsegmentöffnung eingreifenden Vorsprung auf, während der andere Kontaktfederarm von zwei Schutzlaschen zumindest teilweise überragt wird. Diese Variante der verschiedenartigen Ausbildung des Überbiegeschutzes für die beiden Kontaktfederarme lässt sich bei einem als Stanzbiegeteil ausgebildeten Anschlusselement auf besonders einfache Weise realisieren.According to a particularly preferred embodiment, however, one contact spring arm has a projection engaging in a wall segment opening, while the other contact spring arm is at least partially surmounted by two protective tabs. This variant of the various types of overbending protection for the two contact spring arms can be implemented in a particularly simple manner in the case of a connecting element designed as a stamped and bent part.

Gemäß einer weiteren Ausführungsform ist ein Überbiegeschutz für die Verriegelungszunge im Bereich eines freien, in Steckrichtung gesehen also hinteren, Endes der Verriegelungszunge vorgesehen. Durch diesen Überbiegeschutz ist auch die Verriegelungszunge vor einer Beschädigung, z.B. durch zu starkes Umbiegen bei einem unsachgemäßen Einbringen des Anschlusselements in ein Gehäuse, geschützt. Der Überbiegeschutz trägt also dazu bei, eine zuverlässige Funktion der Verriegelungszunge und somit eine sichere Arretierung des Anschlusselements in einem Gehäuse dauerhaft zu gewährleisten.According to a further embodiment, a Überbiegeschutz for the locking tongue in the region of a free, so seen in the insertion direction, the rear end of the locking tongue is provided. By this Überbiegeschutz and the locking tongue from damage, for example, by over-bending in case of improper insertion of the connection element in a housing, protected. The overbend protection carries So helping to ensure a reliable function of the locking tongue and thus secure locking of the connection element in a housing permanently.

Bevorzugt ist der Überbiegeschutz für die Verriegelungszunge an gegenüberliegenden Seiten der Verriegelungszunge wirksam. Dies verhindert, dass sich die Verriegelungszunge bei einer unsachgemäßen Verwendung des Anschlusselements verwinden kann.The overbending protection for the locking tongue is preferably effective on opposite sides of the locking tongue. This prevents the locking tongue from twisting due to improper use of the connection element.

Vorteilhafterweise umfasst der Überbiegeschutz für die Verriegelungszunge ein Wandsegment des Buchsenabschnitts und einen aus der Verriegelungszunge seitlich hervorgehenden und in Richtung des Wandsegments umgebogenen Vorsprung. Das Wandsegment und der Vorsprung sind bevorzugt so miteinander ausgerichtet, dass der Vorsprung auf dem Wandsegment aufsitzt, wenn die Verriegelungszunge nach innen gedrückt wird, und dadurch eine weitere Verformung der Verriegelungszunge verhindert wird.Advantageously, the overbending protection for the locking tongue comprises a wall segment of the bushing section and a projection projecting laterally out of the locking tongue and bent in the direction of the wall segment. The wall segment and the projection are preferably aligned with each other so that the projection is seated on the wall segment when the locking tongue is pressed inwardly, thereby preventing further deformation of the locking tongue.

Alternativ oder zusätzlich und insbesondere auf der dem Vorsprung gegenüberliegenden Seite der Verriegelungszunge umfasst der Überbiegeschutz einen aus einem Wandsegment des Buchsenabschnitts hervorgehenden und nach innen umgebogenen Stützabschnitt. Bevorzugt ist der Stützabschnitt derart nach innen umgebogen, dass die Verriegelungszunge, wenn sie nach innen gedrückt wird, etwa in dem Biegezustand auf dem Stützabschnitt aufsitzt, in welchem ein an der gegenüberliegenden Seite der Verriegelungszunge vorgesehener umgebogener Vorsprung auf einem zugeordneten Wandsegment aufsitzt. Auf diese Weise ist sichergestellt, dass der Überbiegeschutz seine schützende Wirkung gleichzeitig auf beiden Seiten der Verriegelungszunge entfaltet, wodurch ein Verwinden der Verriegelungszunge zuverlässig vermieden wird.Alternatively or additionally, and in particular on the opposite side of the projection of the locking tongue of Überbiegeschutz includes a protruding from a wall segment of the female portion and inwardly bent support portion. Preferably, the support portion is bent inwardly so that the locking tongue, when pressed inwards, approximately in the bending state on the support portion is seated, in which a provided on the opposite side of the locking tongue bent projection on an associated wall segment. In this way, it is ensured that the overbending protection unfolds its protective effect simultaneously on both sides of the locking tongue, whereby a twisting of the locking tongue is reliably prevented.

Weiterer Gegenstand der Erfindung ist außerdem ein Verfahren mit den Merkmalen des Anspruchs 12, durch welches ein elektrisches Anschlusselement der voranstehend beschriebenen Art in besonders vorteilhafter Weise herstellbar ist.Another object of the invention is also a method having the features of claim 12, by which an electrical connection element of the type described above can be produced in a particularly advantageous manner.

Wie in Fig. 1 bis 3 gezeigt ist, umfasst das Anschlusselement einen Buchsenabschnitt 10 zur Aufnahme eines Steckkontakts, welcher an seinem vorderen Ende eine Einführöffnung 12 zum Einführen des Steckkontakts aufweist und welcher an seinem hinteren Ende in einen im vorliegenden Ausführungsbeispiel als Crimpabschnitt ausgebildeten Verbindungsabschnitt 14 zur Verbindung des Anschlusselements mit einer elektrischen Leitung übergeht.As shown in FIGS. 1 to 3, the connecting element comprises a socket portion 10 for receiving a plug contact, which has at its front end an insertion opening 12 for insertion of the plug contact and which at its rear end in a connecting portion formed in the present embodiment as a crimping section 14 for connecting the connection element with an electrical line passes.

Der Buchsenabschnitt 10 weist einen im Wesentlichen rechteckigen und zumindest annähernd quadratischen Querschnitt auf (Fig. 4).The bushing section 10 has a substantially rectangular and at least approximately square cross section (FIG. 4).

Wie insbesondere Fig. 2 zu entnehmen ist, umfasst der Buchsenabschnitt 10 einen oberen Kontaktfederarm 16, der an einer Rückseite eines hinteren oberen Wandsegments 18 des Buchsenabschnitts 10 aus diesem hervorgeht und so nach innen eingeschlagen ist, dass er sich in Richtung der Einführöffnung 12 erstreckt. Der obere Kontaktfederarm 16 ist also mit seinem hinteren Ende an dem hinteren oberen Wandsegment 18 angelenkt, während er sich an seinem vorderen freien Ende 20 an einem im Bereich der Einführöffnung 12 gelegenen, vorderen oberen Wandsegment 36 abstützt.As can be seen in particular from FIG. 2, the bushing section 10 comprises an upper contact spring arm 16 which emerges from a rear side of a rear upper wall segment 18 of the bushing section 10 and is turned inwards such that it extends in the direction of the insertion opening 12. The upper contact spring arm 16 is thus hinged at its rear end to the rear upper wall segment 18, while it is supported at its front free end 20 at a located in the region of the insertion opening 12, front upper wall segment 36.

Der obere Kontaktfederarm 16 ist im Bereich seines vorderen Endes 20 mit einem seitlichen Vorsprung 22 versehen, welcher in eine Öffnung 24 eingreift, die in einem ersten Seitenwandsegment 26 des Buchsenabschnitts 10 ausgebildet ist. Durch den Vorsprung 22 ist der obere Kontaktfederarm 16 in der Öffnung 24 abgestützt.The upper Kontaktfederarm 16 is provided in the region of its front end 20 with a lateral projection 22 which engages in an opening 24 which is formed in a first side wall segment 26 of the female portion 10. By the projection 22 of the upper Kontaktfederarm 16 is supported in the opening 24.

Der in die Öffnung 24 eingreifende Vorsprung 22 bildet einen Überbiegeschutz für den oberen Kontaktfederarm 16 und verhindert, dass der obere Kontaktfederarm 16 bei einem unsachgemäßen Einführen eines Steckkontakts in den Buchsenabschnitt 10 übermäßig stark nach außen umgebogen und somit beschädigt werden kann.The engaging in the opening 24 projection 22 forms a Überbiegeschutz for the upper Kontaktfederarm 16 and prevents the upper Kontaktfederarm 16 can be excessively strongly bent outwards and thus damaged in improper insertion of a plug contact in the socket portion 10.

Der Buchsenabschnitt 10 umfasst ferner einen unteren Kontaktfederarm 28, der an einer Vorderseite eines unteren hinteren Wandsegments 30 des Buchsenabschnitts 10 aus diesem hervorgeht und sich in Richtung der Einführöffnung 12 erstreckt (Fig. 3). Der untere Kontaktfederarm 28 ist mit seinem hinteren Ende also an den Buchsenabschnitt 10 angelenkt, während er sich an seinem vorderen freien Ende 32 an einem im Bereich der Einführöffnung 12 gelegenen, vorderen unteren Wandsegment 34 des Buchsenabschnitts 10 abstützt (Fig. 1 und 4).The female portion 10 further includes a lower contact spring arm 28 which is attached to a front side of a lower rear wall segment 30 of the Socket portion 10 emerges from this and extends in the direction of the insertion opening 12 (Fig. 3). The lower contact spring arm 28 is thus articulated with its rear end to the socket portion 10, while it is supported at its front free end 32 at a located in the region of the insertion opening 12, front lower wall segment 34 of the socket portion 10 (Fig. 1 and 4).

Aus dem vorderen unteren Wandsegment 34 und dem gegenüberliegenden vorderen oberen Wandsegment 36 geht jeweils eine Führungslasche 38 hervor, die nach innen eingeschlagen ist, um ein korrektes Einführen eines Steckkontakts in den Buchsenabschnitt 10 zu erleichtern und eine Beschädigung der Kontaktfederarme 16, 28 im Bereich ihrer freien Enden 20, 32 zu verhindern.From the front lower wall segment 34 and the opposite front upper wall segment 36 is in each case a guide tab 38 protrudes, in order to facilitate a correct insertion of a plug in the socket portion 10 and damage the contact spring arms 16, 28 in the region of their free To prevent ends 20, 32.

Wie Fig. 2 und 3 zu entnehmen ist, laufen die Kontaktfederarme 16, 28 ausgehend von ihren hinteren Enden in Richtung der Einführöffnung 12 zunächst aufeinander zu und anschließend wieder auseinander (Fig. 2 und 3). Die Kontaktfederarme 16, 28 formen somit eine Engstelle, die einen Kontaktbereich 40 zur Kontaktierung eines in dem Buchsenabschnitt 10 aufgenommenen Steckkontakts bildet.As can be seen in FIGS. 2 and 3, the contact spring arms 16, 28 initially run towards one another from their rear ends in the direction of the insertion opening 12 and then apart again (FIGS. 2 and 3). The contact spring arms 16, 28 thus form a constriction, which forms a contact region 40 for contacting a plug-in contact received in the socket section 10.

Auch der untere Kontaktfederarm 28 ist mit einem Überbiegeschutz versehen, der den Kontaktfederarm 28, z.B. bei einem unsachgemäßen Einführen eines Steckkontakts in den Buchsenabschnitt 10, vor einem übermäßigen Umbiegen nach außen schützt. Der Überbiegeschutz des unteren Kontaktfederarms 28 ist durch zwei Schutzlaschen 42 gebildet, die an einer Unterseite der Seitenwandabschnitte 26 aus diesen hervorgehen und so weit aufeinander zu umgebogen sind, dass sie den unteren Kontaktfederarm 28 im Bereich des Kontaktbereichs 40 zumindest teilweise überragen (Fig. 3).Also, the lower contact spring arm 28 is provided with a Überbiegeschutz that protects the Kontaktfederarm 28, for example, in case of improper insertion of a plug contact in the socket portion 10, from excessive bending outwards. The overbend protection of the lower contact spring arm 28 is formed by two protective tabs 42 which emerge from an underside of the side wall sections 26 and are bent over so far that they project at least partially beyond the lower contact spring arm 28 in the region of the contact region 40 (FIG. 3). ,

Der Buchsenabschnitt 10 weist an seiner Oberseite ferner eine Verriegelungszunge 44 auf, die dazu dient, das Anschlusselement in einem entsprechend ausgebildeten Gehäuse zu arretieren.The socket portion 10 also has on its upper side a locking tongue 44, which serves to lock the connection element in a correspondingly designed housing.

Die Verriegelungszunge 44 geht an einer der Führungslasche 38 abgewandten Seite des vorderen oberen Wandsegments 36 aus diesem hervor und erstreckt sich nach hinten. Damit die Verriegelungszunge 44 hinter einem Rastvorsprung eines Gehäuses für das Anschlusselement einrasten kann, ist die Verriegelungszunge 44 in Richtung ihres hinteren, freien Endes 46 nach außen, d.h. also nach oben, umgebogen.The locking tongue 44 extends on a side facing away from the guide tab 38 of the front upper wall segment 36 from this and extends to the rear. In order for the locking tongue 44 to latch behind a locking projection of a housing for the connection element, the locking tongue 44 is in the direction of its rear, free end 46 to the outside, i. So up, bent over.

Die Verriegelungszunge 44 verläuft auf der dem unteren Kontaktfederarm 28 abgewandten Seite des oberen Kontaktfederarms 16, d.h. also außerhalb des oberen Kontaktfederarms 16. Die Verriegelungszunge 44 bietet somit einen gewissen Schutz für den oberen Kontaktfederarm 16 gegen äußere Einflüsse.The locking tongue 44 extends on the side of the upper Kontaktfederarms 16 facing away from the lower Kontaktfederarm 28, i. ie outside the upper contact spring arm 16. The locking tongue 44 thus provides some protection for the upper contact spring arm 16 against external influences.

Um die Verriegelungszunge 44 im Falle eines unsachgemäßen Gebrauchs des Anschlusselements vor einer Beschädigung durch übermäßiges Verbiegen nach innen bzw. unten zu schützen, ist auch die Verriegelungszunge 44 mit einem Überbiegeschutz versehen.In order to protect the locking tongue 44 in case of improper use of the connection element from damage due to excessive bending inwards or downwards, and the locking tongue 44 is provided with a Überbiegeschutz.

Dieser umfasst einen im Bereich des freien Endes 46 der Verriegelungszunge 44 seitlich aus dieser hervorgehenden Vorsprung 48, welcher etwa rechtwinklig nach unten umgebogen und mit einem Stützabschnitt 50 eines zweiten Seitenwandsegments 51 ausgerichtet ist (Fig. 2). Auf der gegenüberliegenden Seite der Verriegelungszunge 44 umfasst der Überbiegeschutz eine Stützlasche 52, die aus dem ersten Seitenwandsegment 26 hervorgeht und soweit nach innen umgebogen ist, dass sich ihr freies Ende 54 unterhalb der Verriegelungszunge 44 befindet.This comprises a projecting in the region of the free end 46 of the locking tongue 44 laterally from this projection 48 which is bent approximately at right angles and aligned with a support portion 50 of a second side wall segment 51 (Fig. 2). On the opposite side of the locking tongue 44, the overbend protection comprises a support tab 52, which consists of the first side wall segment 26 emerges and is bent inward so far that its free end 54 is below the locking tongue 44.

Die Stützlasche 54 einerseits und der seitliche Vorsprung 48 und der Stützabschnitt 50 andererseits sind dabei so bemessen, dass die Verriegelungszunge 44, wenn sie nach unten bzw. innen gedrückt wird, zumindest annähernd gleichzeitig auf der Stützlasche 52 bzw. über den Vorsprung 48 auf dem Stützabschnitt 50 aufsitzt. Durch dieses beidseitige Abstützen der Verriegelungszunge 44 wird ein Verwinden der Verriegelungszunge 44 beim Herunterdrücken der Verriegelungszunge 44 verhindert.The support tab 54 on the one hand and the lateral projection 48 and the support portion 50 on the other hand are dimensioned so that the locking tongue 44, when pressed down or inside, at least approximately simultaneously on the support tab 52 and on the projection 48 on the support portion 50 is seated. By this two-sided support of the locking tongue 44 a twisting of the locking tongue 44 during depression of the locking tongue 44 is prevented.

Wie bereits erwähnt wurde, handelt es sich bei dem vorliegenden Anschlusselement um ein Stanzbiegeteil. Zur Herstellung des Anschlusselements wird zunähst eine entsprechende Platine 56 aus einem Metallblech ausgestanzt (Fig. 5). Dabei werden nicht nur die äußeren Konturen der Platine 56 und Öffnungen 24, 58 ausgestanzt, sondern auch Schnitte 60 vorgenommen.As already mentioned, the present connection element is a stamped and bent part. To produce the connecting element, a corresponding blank 56 is first punched out of a metal sheet (FIG. 5). Not only the outer contours of the board 56 and openings 24, 58 are punched out, but also cuts 60 made.

Damit sich der untere Kontaktfederarm 28 mit seinem vorderen freien Ende 32 an dem vorderen unteren Wandsegment 34 abstützen kann, muss der den unteren Kontaktfederarm 28 bildende Abschnitt der Platine 56 gestreckt werden. Zu diesem Zweck wird der den unteren Kontaktfederarm 28 bildende Abschnitt zunächst relativ zu den Abschnitten, die das vordere untere Wandsegment 34 bzw. die Stützlaschen 42 bilden, versetzt und dann durch Ausübung einer Presskraft abgeflacht.In order for the lower contact spring arm 28 with its front free end 32 to be supported on the front lower wall segment 34, the portion of the circuit board 56 forming the lower contact spring arm 28 has to be stretched. For this purpose, the portion forming the lower contact spring arm 28 is first offset relative to the portions constituting the front lower wall segment 34 and the support tabs 42, respectively, and then flattened by applying a pressing force.

In ähnlicher Weise wird der die Verriegelungszunge 44 bildende Abschnitt gestreckt bzw. abgeflacht, um die Länge der Verriegelungszunge 44 in Steckrichtung gesehen zu vergrößern.Similarly, the locking tongue 44 forming portion is stretched or flattened to increase the length of the locking tongue 44 seen in the insertion direction.

Durch das Abflachen des unteren Kontaktfederarms 28 und der Verriegelungszunge 44 wird in vorteilhafter Weise auch deren Materialfestigkeit erhöht sowie deren Steifigkeit verringert.The flattening of the lower contact spring arm 28 and the locking tongue 44 also advantageously increases its material strength and reduces its rigidity.

Nach erfolgter Abflachung des unteren Kontaktfederarms 28 und der Verriegelungszunge 44 wird die Platine 56 entlang der Biegelinien 62 umgebogen und das Anschlusselement in seine endgültige Form gebracht (Fig. 1 bis 4).After flattening of the lower Kontaktfederarms 28 and the locking tongue 44, the board 56 is bent along the bending lines 62 and brought the connection element in its final form (Fig. 1 to 4).

Dabei dient der in die Öffnung 24 des Seitenwandabschnitts 26 eingreifende seitliche Vorsprung 22 des oberen Kontaktfederarms 16 nicht nur als Überbiegeschutz für den oberen Kontaktfederarm 16, sondern auch als Verriegelung für den Buchsenabschnitt 10, d.h. er verhindert, dass sich der Buchsenabschnitt 10 selbsttätig öffnen kann.Here, the engaging in the opening 24 of the side wall portion 26 lateral projection 22 of the upper Kontaktfederarms 16 serves not only as Überbiegeschutz for the upper Kontaktfederarm 16, but also as a lock for the female section 10, ie it prevents the female section 10 can open automatically.
