Description
In einem Gehäuse angeordneter Druckfederkontakt In a housing arranged compression spring contact
Die Erfindung betrifft einen in einem Gehäuse angeordneten Druckfederkontakt aus einem bandartigen Material nach dem Oberbegriff des Anspruchs 1 und ein Verfahren zu dessen Herstellung.The invention relates to a housing arranged in a compression spring contact of a strip-like material according to the preamble of claim 1 and a method for its preparation.
Es ist bekannt, in Tragschienen Busleisten einzusetzen, die mit mehreren parallel verlaufenden Leiterbahnen oder Stromschienen versehen sind, welche senkrecht von oben mit einem Druckfederkontakt kontaktiert werden, die aus einem Flachmaterial beste- hen.It is known to use bus bars in mounting rails, which are provided with a plurality of parallel conductor tracks or busbars which are contacted perpendicularly from above with a compression spring contact consisting of a flat material.
Um eine genügende Federkraft aufzubringen, weisen diese Druckfederkontakte einen genügend langen Hebel- bzw. Federarm auf, der sich im Wesentlichen in Anreihrichtung erstreckt, was allerdings das Problem mit sich bringt, dass die Baubreite in An- reihrichtung erhöht wird.In order to apply sufficient spring force, these spring-loaded contacts have a sufficiently long lever arm or spring arm, which extends essentially in the direction of arrangement, but this entails the problem that the width is increased in the direction of arrival.
Die Erfindung hat die Aufgabe, dieses Problem zu beheben.The invention has the object to remedy this problem.
Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruchs 1. Sie schafft ferner das Gehäuse des Anspruchs 9.The invention solves this problem by the subject matter of claim 1. It also provides the housing of claim 9.
Derart ist der Federarm über mehrere - wenigstens zwei - Biegungen oder Faltungen in wenigstens zwei oder mehr vorzugsweise direkt in vertikaler Richtung über dem Kontaktbereich übereinander liegende Federbereiche unterteilt, was den für den Druckfederkontakt in Anreihrichtung erforderlichen Bauraum verringert.In this way, the spring arm is subdivided into a plurality of - at least two - bends or folds in at least two or more preferably directly in the vertical direction over the contact region overlying spring areas, which reduces the space required for the compression spring contact in the mounting direction.
Vorteilhafte Ausgestaltungen der Erfindung sind den Unteransprüchen zu entnehmen. Die Erfindung schafft auch ein vorteilhaftes Verfahren zur Herstellung eines Druckfederkontaktes, insbesondere zur Herstellung eines Druckfederkontaktes nach einem der vorstehenden Ansprüche, gekennzeichnet durch folgende Schritte: a) ein Metallband wird in ein Vorstanzwerkzeug eingelegt und es wird vorzugsweise ein Lötpin/Anlötbereich freigeschnitten und es wird wenigstens ein Kontaktierungsabschnitt mit wenigstens einer Kontaktfläche freigeschnitten; b) es erfolgt ein Oberflächenbe- handeln des vorgestanzten Druckfederkontaktes aus Schritt a); und c) es erfolgt ein Fertigbearbeiten des oberflächenbehandelten Druckfederkontaktes durch weitere Stanz- und/oder Biegevorgänge.Advantageous embodiments of the invention can be found in the dependent claims. The invention also provides an advantageous method for producing a compression spring contact, in particular for producing a compression spring contact according to one of the preceding claims, characterized by the following steps: a) a metal band is inserted into a pre-punching tool and preferably a solder pin / Anlötbereich is cut free and it is at least a contacting portion cut free with at least one contact surface; b) there is a surface treatment of the pre-punched compression spring contact from step a); and c) finishing of the surface-treated compression spring contact takes place by means of further punching and / or bending operations.
Besonders vorteilhaft sind hierbei das Fertigen in den drei Phasen und die Ausführung des Kontaktbereichs durch die beschriebene Oberflächenbehandlung. Durch diese beiden Punkte ist sichergestellt, dass nach dem Aufbringen der Oberfläche an wichtigen Kontaktpunkten diese nicht mehr durch Biegeprozesse beschädigt wird.Particularly advantageous in this case are the manufacturing in the three phases and the execution of the contact area by the described surface treatment. These two points ensure that after applying the surface at important contact points, it is no longer damaged by bending processes.
Vorzugsweise umfasst das Oberflächenbehandeln des Schrittes a. folgende Teilschritte: i) der Druckfederkontakte aus Schritt a) wird vernickelt, ii) vorzugsweise wird daraufhin der Anlötbereich verzinnt; und iii) zumindest die Kontaktfläche oder die Kontaktflächen wird/werden vergoldet.Preferably, the surface treatment of step a comprises. the following sub-steps: i) the compression spring contacts of step a) is nickel-plated, ii) then, preferably, the Anlötbereich is tinned; and iii) at least the contact surface or contact surfaces are gold plated.

Figur 1 zeigt in einer Sprengansicht eine Leiterplatte 1 , die zum Einsetzen in ein hier nicht dargestelltes Elektronikgehäuse ausgebildet ist, welches auf eine hutförmige Tragschiene 2 aufrastbar ist.FIG. 1 shows a circuit breaker view of a printed circuit board 1, which is designed for insertion into an electronics housing, not shown here, which can be latched onto a hat-shaped mounting rail 2.
In die hutförmige Tragschiene 2 wird in hier nicht näher dargestellter Weise eine Busleiste 3 eingesetzt, die mehrere Stromschienen oder Leiterbahnen 4 trägt.In the hat-shaped mounting rail 2, a bus bar 3 is used in a manner not shown here, which carries a plurality of bus bars or tracks 4.
An der Leiterplatte 1 wird ein mehrteiliger Busleiterabschnitt 5, beispielsweise durch Löten befestigt, welcher dazu dient, die sich in Haupterstreckungsrichtung X der Tragschiene erstreckenden Kontaktbahnen 4 der Busleiste 3 zu kontaktieren.On the circuit board 1, a multi-part bus conductor section 5, for example, fixed by soldering, which serves to contact the extending in the main direction X of the support rail contact tracks 4 of the bus bar 3.
Hierzu weist der Busleiterabschnitt 5 ein hier mehrteiliges Gehäuse 6 mit einer Gehäu- sevorderwand 7 und einer Gehäuserückwand 8 auf, welches dazu ausgelegt ist, mehrere aus einem Flachmaterial bestehende, parallel zueinander angeordnete Druckfederkontakte 9 aufzunehmen, die dazu ausgelegt sind, die einzelnen Kontaktbahnen jeweils zu kontaktieren. Figur 2 veranschaulicht, dass die Druckfederkontakte 9 senkrecht nach unten zur Tragschiene hin aus dem Gehäuse 6, in dem sie abgestützt sind, mit einem Kontaktierungs- ab schnitt 10 vorstehen.For this purpose, the bus conductor section 5 has a multi-part housing 6 with a housing front wall 7 and a housing rear wall 8, which is designed to receive a plurality of pressure spring contacts 9 arranged parallel to one another and designed to feed the individual contact paths to contact. FIG. 2 illustrates that the compression spring contacts 9 protrude vertically downward from the housing 6, in which they are supported, with a contacting section 10.
Vorzugsweise ist das bandartige Material in diesem Abschnitt geschlitzt ausgebildet, so dass sich der Kontaktierungsabschnitt 10 in zwei Kontaktierungsbereiche 11, 12 unterteilt.Preferably, the band-like material is slit in this section, so that the contacting section 10 is divided into two contacting areas 11, 12.
Die Druckfederkontakte 9 bestehen aus einem metallischen Bandmaterial mit federnden und gut leitenden elektrischen Eigenschaften, wobei sie auch aus einem Federma- terial wie einem Federstahl bestehen können, der mit einem gut leitenden Material beschichtet ist.The compression spring contacts 9 are made of a metallic strip material with resilient and highly conductive electrical properties, and they can also consist of a spring material such as a spring steel, which is coated with a highly conductive material.
Figur 2 zeigt die Anordnung im montierten Zustand an einer Leiterplatte in einer Vorderansicht und Figur 3 die Anordnung der Figur 2 mit einem leicht veränderten Aus- schnitt in einer Rückansicht.FIG. 2 shows the arrangement in the assembled state on a printed circuit board in a front view, and FIG. 3 shows the arrangement of FIG. 2 with a slightly modified cutout in a rear view.
Figuren 4 und 5 veranschaulichen, wie in kontaktierter Stellung die Druckfederkontakte 9, die nur eben gerade zu erkennen sind, auf die Leiterbahnen bzw. Kontaktbahnen 4 des Busabschnittes 5 gedrückt sind und diesen sicher kontaktieren.FIGS. 4 and 5 illustrate how, in the contacted position, the compression spring contacts 9, which can only just be seen straight, are pressed onto the conductor tracks or contact tracks 4 of the bus section 5 and contact them securely.
Der Kontaktierungsabschnitt 10 bildet dabei das eine Ende des Druckfederkontaktes 9 aus. Der Kontaktierungsabschnitt 10 - siehe Fig. 8 - ist über einen Federarm 27 mit einem Anlötbereich an der Leiterplatte verbunden, wobei der Federarm 27 hier federnde und nicht federnde Bereiche und Abschnitte aufweist. Damit sind die Druckfeder- kontakte bzw. die Druckfederkontakte 9 hier vorteilhaft derart ausgebildet und ausgerichtet, dass sie sich ausgehend von einem Anlötbereich 13 an der Leiterplatte im wesentlichen vertikal nach unten in Richtung der Stromschiene erstrecken und in Haupt- erstreckung srichtung X der Tragschiene nur eine geringe Erstreckung aufweisen. Dazu ist der Federarm 27 über mehrere Biegungen oder Faltungen wellenförmig in wenigstens zwei oder mehr vorzugsweise direkt vertikal über dem Kontaktbereich liegende Teilbereiche unterteilt, was den für den Druckfederkontakt in Anreihrichtung erforderlichen Bauraum verringert. Die Druckfederkontakte weisen also nicht - wie oftmals nach dem Stand der Technik - einen sich im wesentlichen in Anreihrichtung X der Leiterplatte über eine größere Strecke erstreckenden Abschnitt auf, der als der Federarm hebelartig die Federkraft erzeugt.The contacting section 10 forms one end of the compression spring contact 9. The contacting portion 10 - see Fig. 8 - is connected via a spring arm 27 with a Anlötbereich to the circuit board, the spring arm 27 here has resilient and non-resilient areas and sections. Thus, the Druckfeder- contacts or the compression spring contacts 9 are here advantageously designed and aligned so that they extend from a Anlötbereich 13 on the circuit board substantially vertically downwards in the direction of the busbar and in the main extension direction X of the mounting rail only one have a small extent. For this purpose, the spring arm 27 is wavy over several bends or convolutions divided into at least two or more preferably directly vertically above the contact area lying portions, which reduces the space required for the compression spring contact in the mounting direction. The spring-loaded contacts therefore do not have-as is often the case with the prior art-a section which essentially extends in the direction of arrangement X of the printed circuit board over a greater distance and which, as the spring arm, produces the spring force like a lever.
Dies sei nachfolgend näher beschrieben.This will be described in more detail below.
Jeder Druckfederkontakt 9 - siehe Fig. 8 - ist in Richtung des Kontaktierungsbereiches 10 - ausgehend von einem Anlötbereich 13 an der Leiterplatte 1 - mehrfach in sich gebogen ausgeführt, d.h. er weist ausgehend von dem hier in sich bogenförmigen Kon- taktierung sbereich 10 zwei oder mehr - hier drei - Wende- bzw. wendepunktartige Bereiche auf. Dabei kann eine wellenförmige Kontur oder zickzackförmige Kontur in vertikaler Richtung Z senkrecht zur Anreihrichtung X entstehen.Each compression spring contact 9 - see Fig. 8 - is in the direction of the Kontaktierungsbereiches 10 - starting from a Anlötbereich 13 on the circuit board 1 - repeatedly bent in itself executed, i. starting from the here inwardly arcuate contacting region 10, it has two or more, here three, turning or turning point-like regions. In this case, a wave-shaped contour or zigzag contour in the vertical direction Z perpendicular to the mounting direction X arise.
Hier weist der Druckfederkontakt Abschnitte 14, 15, 16, 17 auf, die sich im wesentlichen vertikal zur Tragschiene bzw. zur Kontaktierungsfläche - also hier in Richtung Z bzw. parallel zur Richtung Z und senkrecht zur Anreihrichtung X - erstrecken und die zur Federwirkung nur einem geringen oder keinen Beitrag leisten. Diese Abschnitte 14 - 17 können Fenster bzw. Aussparungen 28 im Gehäuse 6 durchsetzen, so dass sie sich in Anreihrichtung bewegen können. Zusätzlich sind sie vertikal im Gehäuse 6 beweglich.Here, the compression spring contact sections 14, 15, 16, 17, which extend substantially vertically to the mounting rail or the contacting surface - ie here in the direction Z or parallel to the direction Z and perpendicular to the mounting direction X - and the spring action only one make little or no contribution. These sections 14-17 can pass through windows or recesses 28 in the housing 6, so that they can move in the direction of arrangement. In addition, they are vertically movable in the housing 6.
Federnd wirken dagegen die die vertikalen Abschnitte 14, 15, 16, 17 hier winklig zur Anreihrichtung verbindenden Federbereiche 18, 19 und/oder weitere Bereiche (wie der Abschnitt 20), die sich in Richtung Z ausgehend von Biegebereichen 21, 22, 23, 24 bewegen können, so dass der Druckfederkontakt 9 in sich senkrecht zur Tragschiene nach oben federnd zusammendrückbar ist. Die Federbereiche 18, 29 und 20 liegen ver- tikal (in Z-Richtung) bzw. über dem Kontaktbereich direkt übereinander (aber nicht aneinander). Sie sie relativ zueinander wechselweise „zickzackartig" winklig zur Anreihrichtung ausgerichtet, wobei sie zur Tragschiene in einem Winkel zwischen vorzugsweise 0 und 80°, vorzugsweise zwischen 20° und 60°, angeordnet sind.On the other hand, the spring sections 18, 19 and / or further areas (such as section 20) connecting the vertical sections 14, 15, 16, 17 at an angle to the mounting direction, springing in the direction Z starting from bending areas 21, 22, 23, 24, have a springy action can move so that the compression spring contact 9 is resiliently compressible in itself upwards to the mounting rail upwards. Spring areas 18, 29 and 20 are tikal (in the Z direction) or above the contact area directly above each other (but not together). They are aligned relative to each other alternately "zigzag" angled to the mounting direction, wherein they are arranged to the mounting rail at an angle between preferably 0 and 80 °, preferably between 20 ° and 60 °.
Zusätzlich ist hier vorgesehen, dass ein stiftartiger Abschnitt 25 des Gehäuses ein Loch 26 im Druckfederkontakt 9 durchsetzt, so dass hierdurch eine Art Widerlager für die Druckfederkontakte 9 im Gehäuse 6 gebildet wird.In addition, it is provided here that a pin-like portion 25 of the housing passes through a hole 26 in the compression spring contact 9, so that in this way a kind of abutment for the compression spring contacts 9 in the housing 6 is formed.
Wesentlich ist, dass der wirksame Federarm 27 zwischen dem Widerlager und dem Kontaktierungsbereich in mehr als einen, insbesondere mehr als zwei zwischen dem Widerlager und dem Kontaktierungsbereich vertikal übereinander liegende Federbereiche 18, 19, 20 unterteilt ist, so dass das die Druckfederkontakte 9 in Richtung senkrecht zur Tragschiene komprimierbar sind, wodurch im Montagezustand eine An- druckkraft erzeugt wird, die den Druckfederkontakt als das Kontaktelement 9 sicher auf die Busleiste bzw. deren Leiterbahnen 4 drückt, so das auch nach langem Gebrauch in rauer Umgebung (an Maschinen oder dgl.) ein sicherer Kontakt gewährleistet ist.It is essential that the effective spring arm 27 is divided between the abutment and the contact area in more than one, in particular more than two spring areas 18, 19, 20 vertically overlapping between the abutment and the contacting area, so that the compression spring contacts 9 in the direction perpendicular can be compressed to the support rail, whereby a pressure force is generated in the assembled state, which presses the compression spring contact safely as the contact element 9 on the bus bar or their interconnects 4, so even after long use in harsh environment (on machines or the like.) On secure contact is guaranteed.
Die Busleiterabschnitte an der Leiterplatte 1 können gemeinsam mit der Leiterplatte in ein übergeordnetes, reihenklemmenartiges Elektronikgehäuse eingesetzt werden. Die Federkontakte sind aber auch für Applikationen anderer Art geeignet.The bus conductor sections on the printed circuit board 1 can be used together with the printed circuit board in a parent, row clamp-type electronics housing. The spring contacts are also suitable for applications of other types.
Fig. 9a und b zeigen eine Variante eines Busleiterabschnitts 5, der Druckfederkontakte 9 aufweist, die Anlötbereiche 13 zum Anlöten an einer Leiterplatte aufweisen, die sich parallel zu der anzulötenden Leiterplatte erstrecken, so dass sie an dieser in einfacher Weise in SMD-Technik anlötbar sind, wohingegen diese Anlötbereiche nach Fig.8 nach Art von Lötpins ausgebildet sind, welche in Bohrungen 29 der Leiterplatte einsteckbar und an der Leiterplatte verlötbar sind. Vorzugsweise werden die Buskontakte wie folgt hergestellt:9a and b show a variant of a bus conductor section 5 which has compression spring contacts 9 which have soldering regions 13 for soldering to a printed circuit board, which extend parallel to the circuit board to be soldered, so that they can be soldered to them in a simple manner in SMD technology whereas these Anlötbereiche 8 are formed in the manner of solder pins, which can be inserted into holes 29 of the circuit board and soldered to the circuit board. Preferably, the bus contacts are made as follows:
1. Phase (Vorstanzen): ein gerades Metallband wird in ein Vorstanzwerkzeug eingelegt; ein Lötpin/ Anlötbereich 13 wird vollflächig/umlaufend freigeschnitten; einer oder zwei Kontaktierungsabschnitte 10 mit einem oder mehreren Kontakt- flächen/Kontaktierungsbereichen 11, 12 wird/werden freigeschnitten und ggf. ausgestellt.1st phase (pre-punching): a straight metal strip is inserted into a pre-punching tool; a Lötpin / Anlötbereich 13 is fully blank / circumferentially cut free; One or two contacting sections 10 with one or more contact surfaces / contacting areas 11, 12 are / are cut free and possibly exhibited.
2. Phase (Oberflächenbehandlung): es erfolgt ein Vernickeln des kompletten Kontakts; - es erfolgt ein Verzinnen des Lötbereichs 13 (selektiv); es erfolgt ein Schützen, insbesondere ein Vergolden der Kontaktierungsbereiche 11, 12 (selektiv) vorzugsweise im Tauch- oder Brush- Verfahren möglich2nd phase (surface treatment): nickel plating of the complete contact takes place; - There is a tinning of the solder region 13 (selectively); There is a shooter, in particular a gilding of the contacting areas 11, 12 (selectively) preferably in the dip or brush method possible
3. Phase (Fertigstanzwerkzeug): - es erfolgen alle restlichen Biegungen und Abtrennen des Kontakts aus dem Streifen in einem Fertigstanzwerkzeug3rd phase (finish punching tool): all remaining bends and detachment of the contact from the strip are carried out in a final punching tool
Durch das Fertigen in den drei Phasen und insbesondere die Ausführung des Anlötbereichs und/oder des Kontaktierungsbereichs 11, 12 durch die beschriebene Oberflä- chenbehandlung wird gewährleistet, dass nach dem Aufbringen der Oberfläche an den besonders wichtigen Kontaktflächen/punkten wie dem Anlötbereich und/oder insbesondere der Kontaktbereiche zum Kontaktieren der Busleiste diese nicht mehr durch Biegeprozesse beschädigt wird. Damit ergibt sich eine vorteilhafte Oberfläche ohne Rissbildung, die am Kontakt auftritt, wenn die 2. Phase der Herstellung nicht wie vor- stehend beschrieben durchlaufen wurde. BezugszeichenBy manufacturing in the three phases and in particular the execution of the Anlötbereichs and / or the contacting area 11, 12 by the surface treatment described ensures that after the application of the surface at the particularly important contact surfaces / points as the Anlötbereich and / or in particular the contact areas for contacting the bus bar this is no longer damaged by bending processes. This results in an advantageous surface without crack formation, which occurs at the contact, if the second phase of the production was not carried out as described above. reference numeral
