Description
BeriShrunnsschalteranordnuna Die Erfindung bezieht sich auf eine Ferührungsschateranordnuna, bestehend aus innerhalh von Positions-Druckfeldern auf die Vorderseite einer Glasscheibe aufgedampften Metallegie rungen und diesen gegenüberliegend auf der Rückseite der Scheibe hefindlichen Kontaktierungsflächen, die mit Schaltelementen der Tragplatte einer gedruckten Schaltung leitend verbindhar sind.Touch switch arrangement The invention relates to a touch switch arrangement, consisting of within position pressure fields on the front of a pane of glass evaporated metal alloys and these opposite on the back of the Disc hefindlichen contacting surfaces with switching elements of the support plate a printed circuit are conductively connected.
Bei bekannten Berührungsschalteranordnungen dieser Art ist die Tragplatte der gedruckten Schaltung mit Abstand von der Pflckseite der Glasscheibe ortsfest in einer Halterunq angebracht und die leitende Verbindung zwischen der Tragplatte und den auf dieser befindlichen Schaltelementen wird durch auf der Platte befestigte Xontaktfedern bewirkt, die den Abstand zwischen beiden Platten Uberbrücken und auf den Kontaktierungsflächen der Glasscheibenrückseite aufliegen.In known touch switch arrangements of this type, the support plate of the printed circuit at a distance from the stake side of the glass pane mounted in a holder and the conductive connection between the support plate and the switching elements located on this is fastened to the plate by Xontaktfedern causes the bridging of the distance between the two plates and on rest on the contact surfaces of the rear side of the glass pane.
Neben der Schwieriqkeit, die das Anbringen der notwendigen zahlreichen Federn auf der Tragplatte bereitet und dem Platzbedarf der Befestigung, der fUr Leiterbahnen und Schaltelemente der Tragplatte verloren geht, bringen diese bekannten Schalteranordnungen noch den wesentlichen Nachteil des großen Herstellungsaufwandes mit sich, der fflr das Anbringen der Kontaktieungsflächen auf der Rückseite der Glasscheibe notwendig ist. Dieser Aufwand ist besonders grau, wenn es sich um hitzebeständige Glas- oder Keramikplatten handelt, wie sie beispielsweise als Peiz- und Kochplatten verwendet werden.In addition to the difficulty of attaching the necessary numerous Prepares springs on the support plate and the space required for the attachment, which is for Conductor tracks and switching elements of the support plate is lost, bring these known Switch arrangements still have the major disadvantage of the great manufacturing effort with it, the one for attaching the contact surfaces on the back of the Glass pane is necessary. This overhead is especially gray when it comes to heat-resistant Glass or ceramic plates are, for example, as Peiz and hot plates be used.
Der große Herstellungsaufwand erfordert dabei aus wirtschaftlichen Gründ auch entsprechend große Stückzahlen ein- und derselben Anordnung der Kontaktierungsflächen auf der Scheibe.The great manufacturing effort requires it for economic reasons Found correspondingly large numbers of items in and out same arrangement the contact surfaces on the pane.
Der Erfindung liegt die Aufgabe zugrunde, die erwähnten Schwierigkeiten zu vermeiden und die Nachteile zu beseitigen.The invention is based on the problem mentioned avoid and eliminate the disadvantages.
Diese Aufgabe wird dadurch gelöst, daß die Kontaktierungsflächen nicht auf der Rückseite der Glas- bzw. Keramikscheibe sondern auf der Rückseite der Tragplatte der gedruckten Schaltung angeordnet sind, und die Tragplatte mit dieser Rückseite auf die Rückseite der Glasplatte auf leg- und mittels federnder Andruckelemente gegen diese andrückbar ist.This object is achieved in that the contact surfaces do not on the back of the glass or ceramic pane but on the back of the support plate the printed circuit are arranged, and the support plate with this back on the back of the glass plate on laying and by means of resilient pressure elements can be pressed against this.
nie Kontaktierungsflächen lassen sich auf diese Weise mit erprobten und hekannten Techniken auf die Tragplatte der gedruckten Schaltung selbst aufbringen und die Glasplatte hedarf nur der Aufbringung der Positionsdruckfelder mit der aufgedampften Metallegierung auf ihrer Vorderseite. nie auf die Tragplatte der gedruckten Schaltung aufgebrahten Kontaktierungsflächen treten durch das Auflegen und Andrücken der Trannlatte auf die Unterseite der Classcheibe in exakt gleicher Position an die Stelle der bisher mit erhehlichem Herstellungsaufwand auf die Rückseite der Glasscheibe aufgebrachten Kontaktierungsflächen. Anders als diese kennen sie aber durch Wegnehmen der Tragplatte jederzeit von dort wieder entfernt und durch andere ersetzt werden.Contact surfaces can never be tested in this way and apply known techniques to the support plate of the printed circuit itself and the glass plate only needs the application of the position pressure fields with the vapor-deposited Metal alloy on its front. never on the support plate of the printed circuit The contacting surfaces that have been sprayed up occur by placing and pressing the transom on the underside of the class disc in exactly the same position in place of the previously applied to the back of the glass pane with considerable manufacturing effort Contact surfaces. In contrast to this, however, you know by removing the support plate can be removed from there at any time and replaced by others.
Die Ansruckelemente für die Tragplatte können aus Federstiften bestehen, die die Tragplatte in nahe bei den Kontaktierungsflachen gelegenen, nicht leitenden, Bereichen der Tragplattenflache unterfaßt. Zur Vermeidung des Andrückens von Lötpunkten oder Leiterbahnen, die sich neben den Kontaktierungsflächen ebenfalls auf der Rückseite der Tragplatte befinden, an die tInterseite der Glasplatte, kannen, wie die Erfindung weiter vorsieht, die Kontaktierungsflächen auf Abstandsplatten aus leitfähigem oder nichtleitfähigem Werkstoff aufgebracht scin, deren Stärke grösser ist als die Höhe der Lötpunkte bzw. Leiterbahnen.The pressure elements for the support plate can consist of spring pins, the support plate in close proximity to the contact surfaces, non-conductive, Areas of the support plate area grasped. To avoid the pressure of soldering points or conductor tracks, which are located next to the contact areas also on the back the support plate are located on the inside of the glass plate, like the invention further provides the contacting surfaces on spacer plates conductive or non-conductive material applied scin, the thickness of which is greater than the Height of the soldering points or conductor tracks.
Schießlich besteht noch erfindungsgemäß die Möglichkeit, Tragnlatte und Glasscheibe im aufeinandergelegten Zustand miteinander zu verkleben.Finally, according to the invention, there is still the possibility of using a support lath and to glue the glass pane to one another when placed on top of one another.
Die Erfindung wird anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen: Fig. 1 die Schalteranordnuna, auseinandergezogen, in ners pektivischer Darstellung, Fig. 2 die Schalteranordnung in Betriebsstellung im Schnitt, von der Seite qesehen, und Fig. 3 einen Schnitt durch die Tragplatte im vergrösserten Maßstab.The invention is based on the embodiment shown in the drawing explained in more detail. In the drawing: Fig. 1 shows the switch assembly, pulled apart, in a perspective view, Fig. 2 shows the switch arrangement in the operating position in section, seen from the side, and FIG. 3 shows a section through the support plate on a larger scale.
wie aus Fig. 1 ersichtlich, sind die Positionierungsdruckfelder 1 auf der Vorderseite 2a der Glas- oder Keramikplatte 2 angeordnet. nie Kontaktierungsflächen 3 befinden sich auf der wirokseite 4a der Tragplatte 4 der gedruckten Schaltung. Die Leiterbahnen und die Schaltelemente der gedruckten Schaltung sind auf der in Fig. 1 nicht erkennbaren Vorderseite 4b der Tragplatte angeordnet und nur die Lötpunkte 5 dieser Schaltung befinden sich zwischen den Kontaktierungsflächen 3 auf der Rückseite 4a der Tragplatte 4.As can be seen from FIG. 1, the positioning pressure fields 1 arranged on the front side 2a of the glass or ceramic plate 2. never contact surfaces 3 are located on the wirokseite 4a of the support plate 4 of the printed circuit. The conductor tracks and the circuit elements of the printed circuit are on the in Fig. 1 not recognizable front 4b of the support plate is arranged and only the soldering points 5 of this circuit are located between the contact surfaces 3 on the rear 4a of the support plate 4.
Aus Fig. 2 geht hervor, wie die Tragplatte 4, durch Leitscheiben 9 gegen seitliche Verschiebung gesichert, mittels der Federstifte 10, die die Vorderseite 4b in den nichtleitenden Bereichen zwischen den Schaltelementen 8 unterfassen, gegen die Unterseite 2b der Glasplatte 2 gedrfickt wird, wobei die Xontaktierungsflchen 3 an dieser Unterseite anliegen.From FIG. 2 it can be seen how the support plate 4 is provided by guide disks 9 secured against lateral displacement, by means of the spring pins 10, which the front 4b below in the non-conductive areas between the switching elements 8, against the underside 2b of the glass plate 2 is pressed, the Xontaktierungsflchen 3 rest against this underside.
Aus Fig. 3 geht- hervor, das die Kontaktierungsflächen 3 dabei auf Abstandsplatten 7 aufgebracht sind, die hier mittels einer Hohlniet 10 auf der Tragplatte 4 befestigt wurden. nie Starke der Abstandsplatte 7 ist grösser als die Höhe der neben dieser angedeuteten Lötpunkte 5 für die Schaltelerente 8.From Fig. 3 it can be seen that the contact surfaces 3 in this case Spacer plates 7 are applied, here by means of a tubular rivet 10 on the support plate 4 were attached. The thickness of the spacer plate 7 is never greater than the height of the next to this indicated soldering points 5 for the switching element 8.
