Description

Die Erfindung betrifft einen elektrischen Doppelflachfederkontakt mit einer Überfeder gemäß dem ersten Teil von Patentanspruch 1 und geht vom Dokument DE-U-7 313 792 aus.The invention relates to an electrical double flat spring contact with an over-spring according to the first part of claim 1 and is based on document DE-U-7 313 792.

Diese DE-U-7 313 792 zeigt einen Anschlußstekked mit einer U-förmigen Federklammer, die innerhalb des Doppelflachfederkontaktes gelagert ist, wobei sich die freien U-Schenkel der Klammer noch vorne erstrecken und nur mit den abgewinkelten Enden die Federarme von außen beaufschlagen.This DE-U-7 313 792 shows a connecting plug with a U-shaped spring clip which is mounted within the double flat spring contact, the free U-legs of the clip still extending at the front and only acting on the spring arms from the outside with the angled ends.

Elektrische Doppelflachfederkontakte sind aus Blechstanzteilen hergestellt. Bekannt sind Innenüberfedern, die zwischen den Kontaktfederarmen angeordnet sind (DE-PS 2 455 140). Bekannt ist ferner eine Außenüberfeder für einen sogenannten Telefonverbinder. Diese Außenüberfeder ist aber für einen Doppelflachfederkontakt nicht geeignet.Electrical double flat spring contacts are made from stamped sheet metal parts. Inner springs which are arranged between the contact spring arms are known (DE-PS 2 455 140). An outer spring for a so-called telephone connector is also known. However, this external spring is not suitable for a double flat spring contact.

Aus der US-PS 4 168 880 ist eine Kontakthülse mit kreisrundem Querschnitt bekannt, die mit einer hülsenförmigen Überfeder mit ebenfalls kreisrundem Querschnitt bestückt ist. Dabei wird ein aus dem Hülsenkörper frei geschnittener Kontaktarm des Grundkontakthülsenkörpers von einem im Hülsenkörper der Überfeder frei geschnittenen Überfederarm belastet. Die hülsenförmige Überfeder ist am Hülsenkörper des Grundkontakts im Bereich des Federarms des Grundkontakts arretiert und erstreckt sich von der Anbindungsstelle des Federarms des Grundkontakts bis zum Steckbereich des Hülsenkörpers des Grundkontakts.From US-PS 4 168 880 a contact sleeve with a circular cross section is known, which is equipped with a sleeve-shaped spring with a circular cross section. In this case, a contact arm of the basic contact sleeve body that is cut free from the sleeve body is loaded by a spring arm that is cut freely in the sleeve body of the spring. The sleeve-shaped spring is locked on the sleeve body of the basic contact in the area of the spring arm of the basic contact and extends from the connection point of the spring arm of the basic contact to the plug-in area of the sleeve body of the basic contact.

Das Gebrauchsmuster 71 47 278 beschreibt und zeigt einen Doppelflachfederkontakt aus einem Blechstanzteil ohne Überfeder, der Anschlußelemente für einen elektrischen Leiterdraht aufweist und eine kastenförmige, im Querschnitt rechteckige Federarmbasis mit einem Boden, Seitenwänden und einer Decke besitzt, wobei sich von der Decke zwei Federarme nach vorne erstrecken und am Boden zwei Federarme angebunden sind. Die Federarme sind in einer Biegelinie aufeinander zulaufend abgebogen und berühren sich in einer weiteren Biegelinie. Von dort laufen die Endbereiche der Federarme zur Bildung eines Einführtrichters auseinander. Die Decke der Federarmbasis ist längsgeteilt und weist demgemäß zwei Deckenteile auf.The utility model 71 47 278 describes and shows a double flat spring contact made of a stamped sheet metal part without a spring, which has connection elements for an electrical conductor wire and a box-shaped spring arm base with a rectangular cross section, with a base, side walls and a ceiling, with two spring arms pointing forward from the ceiling extend and two spring arms are connected to the ground. The spring arms are bent towards one another in a bending line and touch in a further bending line. From there, the end regions of the spring arms diverge to form an insertion funnel. The ceiling of the spring arm base is longitudinally divided and accordingly has two ceiling parts.

Aufgabe der Erfindung ist, einen Doppelflachfederkontakt mit einer Überfeder zu schaffen, die bei Einführung eines Steckkontakten nicht stärt, eine relativ unkomplizierte Form aufweist und die Außen abmessungen des Doppelflachfederkontakts nicht erheblich vergrößern soll. Ferner soll die Überfeder leicht auf dem Doppelflachfederkontakt angeordnet werden können, unverlierbar sicher auf ihm lagern und einen ausreichenden Federdruck erzeugen.The object of the invention is to provide a double flat spring contact with a spring, which does not strengthen when introducing a plug contact, has a relatively uncomplicated shape and should not significantly increase the external dimensions of the double flat spring contact. Furthermore, the over-spring should be able to be easily arranged on the double flat spring contact, securely held there captively and generating sufficient spring pressure.

Der Doppelflachfederkontakt 1, der erfindungsgemäß mit einer Außenüberfeder 2 bestückbar ist, weist - von hinten nach vorne betrachtet - die Isolationskralle 3, die Leiterdrahtkralle 4, die kastenförmige, im Querschnitt rechteckige Federarmbasis 5 und daran angebundene Federarme auf. Die kastenförmige Federarmbasis 5 besteht aus dem Boden 6, den beiden Seitenwänden 7 mit den freien Vorderkanten 7a und aus den längsgeteilten Deckenteilen 8. In der Längsmitte sind die Kanten 9 der Deckenteile 8 auf Abstand voneinander angeordnet, so daß sich ein Schlitz 10 ergibt. Von jedem Deckenteil 8 erstreckt sich nach vorne ein Federarm 11. Die Federarme befinden sich in der Längsmitte um die Breite des Schlitzes 10 auf Abstand, so daß sich der Schlitz 10 nach vorne unverändert fortsetzt. Deckungsgleich unterhalb der Federarme 11 sind die Federarme 12 angeordnet, die an den Boden 6 angebunden sind (in Fig. 1 daher nicht sichtbar). Die Federarme 11 und 12 sind in den Biegelinien 13 nach unten abgebogen, so daß sie aufeinander zulaufen und sich in der Biegelinie 14 berühren. Von dort laufen die Endbereiche 15 zur Bildung eines Einführtrichters 16 divergierend auseinander (Fig. 8).The double flat spring contact 1, which according to the invention can be fitted with an external spring 2, has - viewed from the rear to the front - the insulation claw 3, the conductor wire claw 4, the box-shaped spring arm base 5 with a rectangular cross section and spring arms connected to it. The box-shaped spring arm base 5 consists of the bottom 6, the two side walls 7 with the free front edges 7a and the longitudinally divided ceiling parts 8. In the longitudinal center, the edges 9 of the ceiling parts 8 are arranged at a distance from one another, so that a slot 10 results. A spring arm 11 extends forward from each cover part 8. The spring arms are spaced in the longitudinal center around the width of the slot 10, so that the slot 10 continues unchanged towards the front. The spring arms 12 are arranged congruently below the spring arms 11 and are connected to the base 6 (therefore not visible in FIG. 1). The spring arms 11 and 12 are bent downward in the bending lines 13 so that they converge and touch in the bending line 14. From there, the end regions 15 diverge to form an insertion funnel 16 (FIG. 8).

Wesentlich ist, daß in jedem Deckenteil 8 ein Winkel, vorzugsweise ein rechter Winkel, ausgeschnitten ist, so daß sich jeweils eine Ausschnittlängskante 8a und eine Ausschnittquerkante 8b ergeben, deren Funktion weiter unten beschrieben wird.It is essential that an angle, preferably a right angle, is cut out in each ceiling part 8, so that there is a cutout longitudinal edge 8a and a cutout transverse edge 8b, the function of which is described below.

Die Außenüberfeder 2 ist zur Achse 17 symmetrisch aufgebaut (Fig. 2) und weist jeweils die unteren Klammerarme 18 und die oberen Klammerarme 19 auf, die im Abstand voneinander an der Überfederarmbasis 20 angeordnet sind. Die Überfederarmbasis 20 wird durch die Biegelinie 21, 22 in den Bodenabschnitt 23, die Seitenwandabschnitte 24 und die Deckenwandabschnitte 25 unterteilt. Zwischen den Klammerarmen 18 ist ein Schlitz 26 vorgesehen, der der Breite des Schlitzes 10 des Doppelflachfederkontakts entspricht. In Verlängerung der Schlitze 26 ist in der Überfederarmbasis 20 eine Rastzunge 27 bis zur Hinterkante 28 der Überfederarmbasis 20 freigeschnitten. Parallel zur Vorderkante 29 der Seitenwandabschnitte 24 verlaufend ist ein Durchschnitt 30 eingebracht, so daß sich ein schmaler Arretierstreifen 31 ergibt. Zudem befindet sich in den Außenkanten 32 der Überfederarmbasis 20 ein parallel zur Hinterkante 28 verlaufender kurzer Einschnitt 33, woraus Lappen 34 resultieren.The outer spring 2 is constructed symmetrically to the axis 17 (FIG. 2) and in each case has the lower clamp arms 18 and the upper clamp arms 19 which are arranged at a distance from one another on the spring arm base 20. The spring arm base 20 is divided by the bending line 21, 22 into the bottom section 23, the side wall sections 24 and the top wall sections 25. A slot 26 is provided between the clamp arms 18, which corresponds to the width of the slot 10 of the double flat spring contact. In the extension of the slots 26, a latching tongue 27 is cut out in the spring arm base 20 up to the rear edge 28 of the spring arm base 20. An average 30 is introduced running parallel to the front edge 29 of the side wall sections 24, so that a narrow locking strip 31 results. In addition, in the outer edges 32 of the spring arm base 20 there is a short incision 33 running parallel to the rear edge 28, from which tabs 34 result.

Die Außenüberfeder 2 ist um die Biegelinie 21 und 22 gebogen, so daß sich eine im Querschnitt rechteckige, kastenförmige Außenüberfederarmbasis 20 ergibt (Fig. 3 bis 6). Dabei liegen sich die Außenkanten 32 im Abstand der Breite des Schlitzes 26 gegenüber. In der Biegelinie 35 sind die Überfederklammerarme 18, 19 einwärts abgebogen, so daß sie aufeinander zulaufen, wobei jedoch die Enden 36 in Abstand voneinander bleiben. In der Knicklinie 37 sind die Endbereiche 36 zweckmäßigerweise nochmals etwas nach einwärts abgeknickt.The outer spring 2 is bent around the bending line 21 and 22, so that there is a box-shaped outer spring arm base 20 with a rectangular cross section (FIGS. 3 to 6). The outer edges 32 lie opposite one another at a distance from the width of the slot 26. In the bending line 35, the spring clip arms 18, 19 are bent inwards so that they converge towards one another, but the ends 36 remain at a distance from one another. In the crease line 37, the end regions 36 are expediently bent a little further inwards.

Nach der Erfindung sind die Lappen 34 mit ihrer Spitze 34a in die Kastenform der Außenüberfederarmbasis 20 einwärts abgebogen und die Arretierstege 31 nach innen durchgedrückt (Fig. 4, 5 und 6).According to the invention, the tabs 34 are bent inward with their tip 34a into the box shape of the outer spring arm base 20 and the locking webs 31 are pushed inwards (FIGS. 4, 5 and 6).

Die Außenüberfeder 2 sitzt auf der kastenförmigen Federarmbasis 5 des Doppelflachfederkontakts 1 gemäß den Fig. 7 bis 10. Dabei sitzt die etwas länger ausgeführte Kastenform der Außenüberfeder etwa formschlüssig über der Kastenform des Doppelflachfederkontakts, wobei die Klammerarme 18 und 19 in der Draufsicht betrachtet, parallel zu den Federarmen 11, 12 des Doppelflachfederkontakts verlaufen. Ihre Breite entspricht zweckmäßigerweise der Breite der Federarme 11, 12. Sie sind jedoch kürzer ausgeführt, so daß die Klammerarme 18, 19 kurz vor der Biegelinie 14 von außen auf die Federarme 11, 12 des Doppelflachfederkontakts drücken. Die Hinterkante 28 der Außenüberfeder 2 schließt mit der Hinterkante 8c der Federarmbasis 5 des Doppelflachfederkontakts ab. Der Durchschnitt 30 ist auf der Länge des Basisteils 20 der Außenüberfeder 2 dort angeordnet, wo sich die Vorderkanten 7a der Seitenwände 7 des Doppelflachfederkontakts fluchtend und parallel verlaufend befinden. Dadurch wird gewährleistet, daß der Steg 31 die Vorderkante 7a hintergreift und ein Zurückschieben der Außenüberfeder 2 auf dem Doppelflachfederkontakt verhindert wird. Der Einschnitt 33 ist in Kombination mit dem Durchschnitt 30 an einer Stelle eingebracht, die fluchtend und parallel zur Kante 8b des jeweiligen Deckenteils 8 verläuft. Durch das Einwärtsbiegen der Spitze 34a hintergreift die Kante 34b der Außenüberfeder 2 die Kante 8b des Doppelflachfederkontakts, so daß eine Verschiebung der Außenüberfeder 2 nach vorne verhindert ist. Die Außenüberfeder 2 aus Stahl sitzt somit fest auf dem Doppelflachfederkontakt.The outer spring 2 is seated on the box-shaped spring arm base 5 of the double flat spring contact 1 according to FIGS. 7 to 10. The somewhat longer box shape of the outer spring is seated approximately positively above the box shape of the double flat spring contact, the clamp arms 18 and 19 being viewed in plan view, parallel to the spring arms 11, 12 of the double flat spring contact. Their width suitably corresponds to the width of the spring arms 11, 12. However, they are shorter, so that the clamp arms 18, 19 press shortly before the bending line 14 from the outside onto the spring arms 11, 12 of the double flat spring contact. The rear edge 28 of the outer spring 2 terminates with the rear edge 8c of the spring arm base 5 of the double flat spring contact. The average 30 is arranged on the length of the base part 20 of the outer spring 2 where the front edges 7a of the side walls 7 of the double flat spring contact are flush and parallel. This ensures that the web 31 engages behind the front edge 7a and prevents the outer spring 2 from being pushed back on the double flat spring contact. The incision 33 is made in combination with the average 30 at a point which is flush and parallel to the edge 8b of the respective ceiling part 8. By bending the tip 34a inward, the edge 34b of the outer spring 2 engages behind the edge 8b of the double flat spring contact, so that a displacement of the outer spring 2 to the front is prevented. The outer spring 2 made of steel is thus firmly seated on the double flat spring contact.
