Definitions
- the invention relates to a double flat spring contact with a stop device.
- the stop device consists of a connected to the outer edge of each fork spring arm of a pair of fork spring arms and at a distance from the outer edge at right angles to the other pair of fork spring arms bent tab and from a web opposite the respective tab on the outer edge of each fork spring arm of the other pair of fork spring arms connected web against which the free end edge of the angled region of the tab abuts.
- the outside of the spacer or stop device is aligned with the end wall of the spring arm base of the double flat spring contact.
- the double flat spring contact is pushed into a cuboid chamber of a connector housing.
- the spacer device can hinder the insertion by the elements of the spacer device protruding outward abutting the chamber wall end edges in the region of the plug-in opening of the chamber. But even if the contact area of the double flat spring contact is threaded, tilting of the double flat spring contact can cause the relatively sharp-edged elements of the spacing devices to abut the chamber walls and cause increased friction, so that they can be inserted of the double flat spring contact in a housing chamber of a connector housing, a relatively high insertion force may be required.
- EP 0 352 871 A3 discloses a flat spring contact which has a conductor wire connection part and a contact part designed as a flat fork spring, the flat fork spring forming a U-shaped spring arm base with a base and two side walls.
- a spring arm is connected to each side wall, extending forward, and these spring arms are bent from the two side walls to a contact line, converging towards one another and diverge from the contact line to form a funnel.
- the flat spring contact is provided with a box-shaped spring which is held in a form-fitting manner on the flat fork spring and has spring arms which rest on the fork spring arms.
- a box web is provided by the over-spring, on which the fork spring arms can be supported with their broad sides in the area of the finding funnel, so as to avoid over-bending of the fork spring arms.
- This flat spring contact is not a double flat spring contact like the contact element described above. Thus, this flat spring contact also has no outwardly projecting stop devices, as mentioned in feature a) of claim 1.
- the object of the invention is to provide a double flat spring contact in which the elements of the spacing device do not impede the insertion of the double flat spring contact into a housing chamber of a plug housing and which ensures a relatively low insertion force.
- the double flat spring contact 1 shown in FIGS. 1 and 2 with external spring 10 is electrical and is formed from a stamped sheet metal part.
- the double flat spring contact 1 consists of an essentially U-shaped spring arm base 4 with two broad side walls 6 and an end wall 7.
- a claw part with claw arms 8 is arranged on one side for attaching an electrical conductor wire, not shown.
- On the other side of the spring arm base 4 are on connected to the front edges of the broad side walls 6, fork spring arms 3 converging in an arc shape, which in the culmination region of the arches form a contact region for a contact tongue, not shown, of a counter-contact.
- protruding stop devices 2 are provided which keep the converging fork spring arms 3 at a certain distance.
- the stop devices 2 consist of web or tab-shaped parts.
- the outer spring 10 essentially consists of a box-shaped spring arm base 13 and a plurality of spring suspension arms 16 adjoining the broad side walls 15 thereof.
- the spring arm base 13 of the outer spring spring 10 has two broad side walls 15 and two end face walls 14, the spring arm base 13 having the spring arm base 4 of the double spring contact 1 on all sides encloses.
- a desired tight contact of the spring arm base 13 of the outer spring 10 on the spring arm base 4 of the double flat spring contact 1 is achieved by holding devices in the form of tabs 17.
- two tabs 17 are formed in each of the side areas, which are bent inward by approximately 180 °, so that the spring arm base 13 is firmly connected to the spring arm base 4.
- 10 skids 11 are provided on the end walls 14 of the spring arm base 13 of the outer over-spring 10 Cover anchor devices 2 from the outside.
- a detent spring tongue 18 is punched out, which serve as clamping devices for the double flat spring contact 1 in a chamber of the connector housing 30 by being slightly bent outwards, such as this is shown in Fig. 2.
- the skids 11 adjoin the end walls 14 of the spring arm base 13 in the direction of the plug housing 30, one skid 11 being provided for each end wall 14.
- the spring fork arms 16 are connected to the broad side walls 15, namely two spring spring arms 16 per broad side wall 15.
- the spring arm base 13 as well as the skids 11 and the spring fork arms 16 are formed in one piece.
- the skids 11 it is the task of the skids 11 to cover the stop devices 2 of the double flat spring contact 1 in order to prevent jamming in the chamber of the connector housing 30. This is done in that the skids 11 extend in a straight line and flat to the spring arm base 13 and abut tightly against the stop devices 2. In order to bring about a better insertion of the double flat spring contact 1, the end regions of the spring fork arms 11 are bent inwards. The kinked areas are shown as bevels 12 and thus form a conical taper of the free end of the outer spring 10. With this conical taper, simple insertion of the double flat spring contact 1 into the corresponding chamber of the plug chamber housing 30 is ensured.
- the spring fork arms 16 are also straight, but run obliquely inwards in order to rest against the free ends of the fork spring arms 3.
- the oblique course of the spring fork arms 16 is produced in that the spring fork arms 16 are bent in their connection area to the spring arm base 13.
- the kink 19 thus formed can be seen in FIG. 2.
- the spring fork arms 16 are shorter.
- the end or the end 20 of the spring fork arms 16 is located approximately at the level of the transition of the skids 11 from the straight course to the bevel 12.
- the spring fork arms 16, which act from the outside against the fork spring arms 3 of the double flat spring contact 1, on the one hand ensure that the free ends of the fork spring arms 3 cannot get caught in the chamber of the connector housing 30.
- the tension between the fork spring arms 3 necessary for receiving a counter-contact pin, not shown, is increased by the tight contact of the spring-loaded fork arms 16.
- FIG. 3 shows a plan view of a skid 11, wherein the spring arm base 13 of the outer spring 10 adjoining the lower end of the skid 11 has been omitted.
- the sliding skid 11 shown has a butt joint 21 in the middle in the longitudinal direction of the sliding skid 11, which also runs through the end wall 14, not shown, of the spring arm base 13 in a corresponding manner.
- the butt seam 21 results from manufacturing reasons, since the outer spring 10 together with the skids 11 and the spring fork arms 16 are stamped in one piece from a sheet metal part.
- the outer spring 10 receives its shape shown in FIGS. 1 and 2 by corresponding bending of the punched sheet metal part into a box-like shape.
- a dovetail-shaped undercut recess 22 is provided on one edge of the butt seam 21, whereas on the other edge the butt seam 21 a correspondingly shaped tab 23 is formed.
- the tab 23 is pressed into the recess 22, so that there is a firm connection or a positive fit of the tab 23 in the recess 22.
- notches 24 are formed, which are bent inwards after the assembly of the outer spring 10 onto the double flat spring contact 1, in order to additionally enable a good connection of the outer spring 10 with the double flat spring contact 1.

Description
Die Erfindung betrifft einen Doppelflachfederkontakt mit Anschlageinrichtung.The invention relates to a double flat spring contact with a stop device.
Auf dem Markt gibt es (interner Stand der Technik) bereits einen Doppelflachfederkontakt mit den Merkmalen a) und b) des Anspruchs 1. Bei diesem Doppelflachfederkontakt besteht die Anschlageinrichtung aus einer an der Außenkante jedes Gabelfederarms des einen Gabelfederarmpaares angebundenen und im Abstand von der Außenkante rechtwinklig zum anderen Gabelfederarmpaar abgebogenen Lasche sowie aus einem der jeweiligen Lasche gegenüberliegend an der Außenkante jedes Gabelfederarms des anderen Gabelfederarmpaares angebundenen Steg, gegen den die freie Endkante des abgewinkelten Bereichs der Lasche stößt. Dabei fluchtet die Außenseite der Abstandhalte- bzw. Anschlageinrichtung jeweils mit der Stirnwandung der Federarmbasis des Doppelflachfederkontakt.There is (internal state of the art) already a double flat spring contact with the features a) and b) of
Der Doppelflachfederkontakt wird in eine quaderförmige Kammer eines Steckergehäuses geschoben. Dabei kann die Abstandhalteeinrichtung das Einführen behindern, indem die nach außen überstehenden Elemente der Abstandhalteeinrichtung gegen die Kammerwandungsstirnkanten im Bereich der Stecköffnung der Kammer stoßen. Aber selbst wenn der Kontaktbereich des Doppelflachfederkontakts eingefädelt ist, können durch Verkantungen des Doppelflachfederkontakts die relativ scharfkantigen Elemente der Abstandhalteeinrichtungen gegen die Kammerwandungen stoßen und schabend eine erhöhte Reibung verursachen, so daß zum Einführen des Doppelflachfederkontakts in eine Gehäusekammer eines Steckergehäuses eine relativ hohe Steckkraft erforderlich sein kann.The double flat spring contact is pushed into a cuboid chamber of a connector housing. The spacer device can hinder the insertion by the elements of the spacer device protruding outward abutting the chamber wall end edges in the region of the plug-in opening of the chamber. But even if the contact area of the double flat spring contact is threaded, tilting of the double flat spring contact can cause the relatively sharp-edged elements of the spacing devices to abut the chamber walls and cause increased friction, so that they can be inserted of the double flat spring contact in a housing chamber of a connector housing, a relatively high insertion force may be required.
Ferner ist in der EP 0 352 871 A3 ein Flachfederkontakt offenbart, der ein Leiterdrahtanschlußteil und einen als Flachgabelfeder ausgebildetes Kontaktteil aufweist, wobei die Flachgabelfeder eine U-förmige Federarmbasis mit einem Boden und zwei Seitenwänden bildet. An jede Seitenwand ist ein Federarm sich nach vorne ersteckend angebunden und diese Federarme sind von den beiden Seitenwänden beginnend bis zu einer Kontaktlinie aufeinander zulaufend abgebogen und divergieren zur Bildung eines Findungstrichters von der Kontaktlinie. Der Flachfederkontakt ist mit einer kastenförmigen Überfeder versehen, die auf der Flachgabelfeder formschlüssig gehalten wird und Überfederarme aufweist, die auf den Gabelfederarmen aufliegen. Im Bereich des Findungstrichters ist ein Kastensteg durch die Überfeder vorgesehen, an dem sich die Gabelfederarme im Bereich des Findungstrichters mit ihren Breitseiten abstützen können, um so eine Überbiegung der Gabelfederarme zu vermeiden.Furthermore, EP 0 352 871 A3 discloses a flat spring contact which has a conductor wire connection part and a contact part designed as a flat fork spring, the flat fork spring forming a U-shaped spring arm base with a base and two side walls. A spring arm is connected to each side wall, extending forward, and these spring arms are bent from the two side walls to a contact line, converging towards one another and diverge from the contact line to form a funnel. The flat spring contact is provided with a box-shaped spring which is held in a form-fitting manner on the flat fork spring and has spring arms which rest on the fork spring arms. In the area of the finding funnel, a box web is provided by the over-spring, on which the fork spring arms can be supported with their broad sides in the area of the finding funnel, so as to avoid over-bending of the fork spring arms.
Dieser Flachfederkontakt ist kein Doppelflachfederkontakt, wie das oben beschriebene Kontaktelement. So weist dieser Flachfederkontakt auch keine nach außen überstehenden Anschlageinrichtungen auf, wie sie im Merkmal a) des Anspruchs 1 genannt sind.This flat spring contact is not a double flat spring contact like the contact element described above. Thus, this flat spring contact also has no outwardly projecting stop devices, as mentioned in feature a) of
Aufgabe der Erfindung ist es, einen Doppelflachfederkontakt zu schaffen, bei dem die Elemente der Abstandhalteeinrichtung das Einführen des Doppelflachfederkontakts in eine Gehäusekammer eines Steckergehäuses nicht behindern und der eine relativ geringe Steckkraft gewährleistet.The object of the invention is to provide a double flat spring contact in which the elements of the spacing device do not impede the insertion of the double flat spring contact into a housing chamber of a plug housing and which ensures a relatively low insertion force.

Der in den Figuren 1 und 2 dargestellte Doppelflachfederkontakt 1 mit Außenüberfeder 10 ist elektrisch und aus einem Blechstanzteil geformt. Der Doppelflachfederkontakt 1 besteht aus einer im wesentlichen U-förmigen Federarmbasis 4 mit zwei Breitseitenwandungen 6 und einer Stirnseitenwandung 7. An die Federarmbasis 4 ist auf der einen Seite ein Krallenteil mit Krallenarmen 8 zum Anschlagen eines nicht dargestellten elektrischen Leiterdrahts angeordnet. Auf der anderen Seite der Federarmbasis 4 sind an die Vorderkanten der Breitseitenwandungen 6 bogenförmig konvergierende Gabelfederarme 3 angebunden, die im Kulminationsbereich der Bögen einen Kontaktbereich für eine nicht dargestellte Kontaktzunge eines Gegenkontakts bilden. Im Kontaktbereich sind überstehende, die konvergierenden Gabelfederarme 3 auf einen bestimmten Abstand haltende Anschlageinrichtungen 2 vorgesehen. Die Anschlageinrichtungen 2 bestehen dabei aus steg- bzw. laschenförmigen Teilen.The double
Die Außenüberfeder 10 besteht im wesentlichen aus einer kastenförmigen Federarmbasis 13 und mehreren, sich an deren Breitseitenwandungen 15 anschließenden Überfedergabelarmen 16. Die Federarmbasis 13 der Außenüberfeder 10 weist zwei Breitseitenwandungen 15 und zwei Stirnseitenwandungen 14 auf, wobei die Federarmbasis 13 die Federarmbasis 4 des Doppelfederkontakts 1 allseitig umschließt. Eine angestrebte dichte Anlage der Federarmbasis 13 der Außenüberfeder 10 an der Federarmbasis 4 des Doppelflachfederkontakts 1 wird durch Halteeinrichtungen in Form von Laschen 17 bewerkstelligt. In den Stirnseitenwandungen 14 der Außenüberfeder 10 sind in den Seitenbereichen jeweils zwei Laschen 17 ausgebildet, die um etwa 180° nach innen umgebogen sind, so daß die Federarmbasis 13 fest mit der Federarmbasis 4 verbunden ist.The
Um erfindungsgemäß das Einführen des Doppelflachfederkontakts 1 in eine Kammer eines Steckergehäuses 30 nicht durch die Elemente der als Abstandshalterung dienenden Anschlageinrichtungen 2 zu behindern und eine relativ geringe Steckkraft zu gewährleisten, sind an den Stirnseitenwandungen 14 der Federarmbasis 13 der Außenüberfeder 10 Gleitkufen 11 vorgesehen, die die Anschlageinrichtungen 2 von außen überdecken.In order not to impede the insertion of the double
In den Breitseitenwandungen 15 der Federarmbasis 13 ist jeweils eine Rastfederzunge 18 ausgestanzt, die als Klemmvorrichtungen für den Doppelflachfederkontakt 1 in einer Kammer des Steckergehäuses 30 dienen, indem sie leicht nach außen gebogen sind, wie dies in Fig. 2 gezeigt ist. An die Stirnseitenwandungen 14 der Federarmbasis 13 schließen sich in Richtung des Steckergehäuses 30 die Gleitkufen 11 an, wobei pro Stirnseitenwandung 14 je eine Gleitkufe 11 vorgesehen ist. An die Breitseitenwandungen 15 dagegen sind die Überfedergabelarme 16 angeschlossen und zwar pro Breitseitenwandung 15 jeweils zwei Überfedergabelarme 16. Die Federarmbasis 13 sowie die Gleitkufen 11 und die Überfedergabelarme 16 sind einstückig ausgebildet.In the
Gemäß der Erfindung ist es Aufgabe der Gleitkufen 11, die Anschlageinrichtungen 2 des Doppelflachfederkontakts 1 zu überdecken, um ein Hakeln in der Kammer des Steckergehäuses 30 zu verhindern. Dies geschieht dadurch, indem sich die Gleitkufen 11 geradlinig und eben zur Federarmbasis 13 nach oben erstrecken und dabei dicht an den Anschlageinrichtungen 2 anliegen. Um ein besseres Einführen des Doppelflachfederkontakts 1 zu bewirken, sind die Endbereiche der Überfedergabelarme 11 nach innen abgeknickt. Die abgeknickten Bereiche stellen sich als Schrägen 12 dar und bilden somit eine konische Verjüngung des freien Endes der Außenüberfeder 10. Mit dieser konischen Verjüngung ist ein einfaches Einführen des Doppelflachfederkontaktes 1 in die entsprechende Kammer des Steckerkammergehäuses 30 gewährleistet.According to the invention, it is the task of the
Die Überfedergabelarme 16 sind ebenfalls geradlinig ausgebildet, verlaufen aber schräg nach innen, um an den freien Enden der Gabelfederarme 3 anzuliegen. Der schräge Verlauf der Überfedergabelarme 16 wird dadurch hergestellt, daß die Überfedergabelarme 16 in ihrem Anschlußbereich an die Federarmbasis 13 abgeknickt sind. Die sich somit bildende Knickstelle 19 ist aus Fig. 2 ersichtlich.The
In Bezug auf die Gleitkufen 11 sind die Überfedergabelarme 16 kürzer ausgebildet. Der Abschluß bzw. das Ende 20 der Überfedergabelarme 16 befindet sich dabei etwa auf der Höhe des Übergangs der Gleitkufen 11 vom geradlinigen Verlauf zur Schräge 12. Die Überfedergabelarme 16, die von außen gegen die Gabelfederarme 3 des Doppelflachfederkontakts 1 anliegen, sorgen einerseits dafür, daß sich die freien Enden der Gabelfederarme 3 nicht in der Kammer des Steckergehäuses 30 verhaken können. Andererseits wird die zur Aufnahme eines nicht dargestellten Gegenkontaktstiftes nötige Spannung zwischen den Gabelfederarmen 3 durch das dichte Anliegen der Überfedergabelarme 16 verstärkt.With regard to the
Fig. 3 zeigt in Draufsicht eine Gleitkufe 11, wobei auf eine Darstellung der sich am unteren Ende der Gleitkufe 11 anschließenden Federarmbasis 13 der Außenüberfeder 10 verzichtet worden ist. Die dargestellte Gleitkufe 11 weist mittig eine in Längsrichtung der Gleitkufe 11 durchgehende Stoßnaht 21 auf, die in entsprechender Weise auch durch die nicht dargestellte Stirnseitenwandung 14 der Federarmbasis 13 verläuft. Die Stoßnaht 21 ergibt sich aus herstellungstechnischen Gründen, da die Außenüberfeder 10 zusammen mit den Gleitkufen 11 und den Überfedergabelarmen 16 einstückig aus einem Blechteil ausgestanzt ist. Die Außenüberfeder 10 erhält ihre in den Fig. 1 und 2 dargestellte Form durch entsprechendes Biegen des ausgestanzten Blechteils in eine kastenartige Form. Die sich nach dem Biegen des Blechstanzteiles gegenüberliegenden freien Kanten bilden dann die dargestellte Stoßnaht 21. Um die Außenüberfeder 10 an der Stoßnaht 21 zu verbinden, ist an der einen Kante der Stoßnaht 21 eine schwalbenschwanzförmige hinterschnittene Ausnehmung 22 vorgesehen, wohingegen an der anderen Kante der Stoßnaht 21 eine entsprechend geformte Lasche 23 ausgebildet ist. Zum Verbinden bzw. Schließen der Stoßnaht 21 wird die Lasche 23 in die Ausnehmung 22 eingedrückt, so daß sich eine feste Verbindung bzw. ein formschlüssiger Sitz der Lasche 23 in der Ausnehmung 22 ergibt.FIG. 3 shows a plan view of a
Am unteren Ende der Gleitkufe 11 sind, wie in Fig. 3 gezeigt, Einschnitte 24 ausgebildet, die nach der Montage der Außenüberfeder 10 auf den Doppelflachfederkontakt 1 nach innen umgebogen werden, um zusätzlich eine gute Verbindung der Außenüberfeder 10 mit dem Doppelflachfederkontakt 1 zu ermöglichen.At the lower end of the
