Description
Die Erfindung bezieht sich zum einen auf eine einstückige Tastaturmatte und zum anderen auf ein elektrisches Gerät.The invention relates firstly to a one-piece keyboard mat and secondly to an electrical device.
Bei einem Kommunikationsendgerät, wie zum Beispiel ein Telefonanrufbeantworter, ist bekannt, ein solches elektrisches Gerät im Querschnitt in stehender L-Form zu bauen mit einem L-Winkel zwischen 90 und 180 Grad. Vorzugsweise ist ein L-Winkel von ungefähr oder gleich 110 Grad gewählt.In a communication terminal, such as a telephone answering machine, it is known to build such an electrical appliance in cross-section in a standing L-shape with an L-angle between 90 and 180 degrees. Preferably, an L angle of about or equal to 110 degrees is selected.
Bei einem solchen Gerät kann sich eine Flachbaugruppe in dem ersten Schenkel der L-Form befinden und kann sich eine Tastatur in dem zweiten Schenkel der L-Form befinden. Beispielsweise sind die Flachbaugruppe in einem ersten, längeren Schenkel und die Tastatur in einem zweiten, kürzeren Schenkel der L-Form untergebracht.In such a device, a printed circuit board may be located in the first leg of the L-shape and a keyboard may be located in the second leg of the L-shape. For example, the printed circuit board in a first, longer leg and the keyboard are housed in a second, shorter leg of the L-shape.
Geräteintern befindet sich zwischen der Tastatur und der Flachbaugruppe eine elektrisch funktionsfähige Verbindung, um Tastenbetätigungen der das Gerät insgesamt steuernden Flachbaugruppe kenntlich zu machen.Internally located between the keyboard and the printed circuit board is an electrically functional connection to key presses of the device controlling the overall printed circuit board identified.
Die in einem solchen Gerät heute verwendeten Tastaturen weisen eine Tastaturmatte mit einem Abschnitt auf, das Tasten mit jeweils wenigstens einem einzigen zugehörigen elektrisch leitenden Kontaktelement umfasst.The keyboards used in such a device today comprise a keypad mat having a portion comprising keys each having at least a single associated electrically conductive contact element.
Ferner ist bekannt, die elektrische Verbindung zwischen der Tastatur und der Flachbaugruppe entweder mit Steckverbindern, mit Drähten oder Flachbandkabeln oder mit Folienverbindern zu realisieren.Furthermore, it is known to realize the electrical connection between the keyboard and the printed circuit board either with connectors, with wires or ribbon cables or with foil connectors.
Nachteilig bei Steckverbindern ist, dass ihre Position fix ist. Steckverbinder weisen keine Flexibilität in der Verbindung auf.A disadvantage of connectors is that their position is fixed. Connectors have no flexibility in the connection.
Bei Drähten oder Flachbandkabeln existiert zwar eine Flexibilität in der Verbindung. Die Kontaktierung ist aber mittels Löten oder Steckverbindern zu bewerkstelligen.In the case of wires or ribbon cables, there is flexibility in the connection. The contact is but to accomplish by means of soldering or connectors.
Bei dem Einsatz von Folienverbindern besteht zwar auch eine Flexibilität in der Verbindung, die Verbindung ist aber ebenfalls mittels Löten zu bewerkstelligen oder es ist der Einsatz von Bügeltechniken notwendig.Although the use of film connectors also provides flexibility in the connection, but the connection is also to accomplish by means of soldering or it is the use of ironing techniques necessary.
Außerdem ist allen vorgenannten Verbindungstechniken in nachteiliger Weise gemeinsam, dass sie aufwändig, zeitintensiv in der Montage und insgesamt teuer sind.In addition, all the above-mentioned joining techniques disadvantageously have in common that they are complicated, time-consuming to install and overall expensive.

Aufgabe der vorliegenden Erfindung ist es daher, ausgehend von einer Tastaturmatte der eingangs genannten Art eine solche Tastaturmatte in der Weise technisch zu verbessern, dass eine kostengünstige, einfache und in der Montagezeit verkürzte Verbindung zwischen der Tastatur und der zugehörigen Flachbaugruppe eines zugehörigen elektrischen Geräts wie oben beschrieben zu realisieren ist.The object of the present invention is therefore, starting from a keyboard mat of the type mentioned in such a keypad to technically improve in such a way that a cost-effective, simple and shortened in the assembly time connection between the keyboard and the associated Flat assembly of an associated electrical device as described above is to realize.
Weiter ist es Aufgabe der Erfindung, ausgehend von einem elektrischen Gerät der eingangs genannten Art, ein solches elektrisches Gerät in der Weise technisch zu verbessern, dass der Montageaufwand, die Montagezeit und die Montagekosten reduziert sind.It is another object of the invention, starting from an electrical device of the type mentioned, to technically improve such an electrical device in such a way that the assembly costs, assembly time and installation costs are reduced.
Bezüglich der Tastaturmatte wird die Aufgabe erfindungsgemäß durch eine Tastaturmatte gelöst, die die im Anspruch 1 angegebenen Merkmale aufweist.With regard to the keyboard mat, the object is achieved by a keypad mat having the features specified in claim 1.
Bezüglich des elektrischen Geräts wird die Aufgabe erfindungsgemäß durch ein elektrisches Gerät gelöst, das die im Anspruch 6 angegebenen Merkmale aufweist.With regard to the electrical device, the object is achieved by an electrical device having the features specified in claim 6.
Die erfindungsgemäße Tastaturmatte weist danach nicht nur einen ersten Abschnitt mit Tasten auf, sondern weist gleichzeitig auch einen die elektrisch leitende Verbindung zwischen dem ersten Abschnitt und einer zugehörigen Flachbaugruppe herstellenden flächigen Verbindungsabschnitt und ein kastenförmiges Positionierelement auf. Dabei ist der Verbindungsabschnitt zwischen dem ersten Abschnitt und dem Fositionierelement angeordnet und sind der erste Abschnitt, der flächige Verbindungsabschnitt und das Positionierelement einstückig aus Silikon gefertigt. Der Verbindungsabschnitt weist auf einer seiner beiden flachen Seiten elektrisch leitende Streifen auf, die elektrisch kontaktierbare Bereiche aufweisen. Die elektrisch leitenden Streifen erstrecken sich in den ersten Abschnitt und sind dort mit Kontaktelementen der Tasten verbunden. Der Verbindungsabschnitt weist an seinen dem Positionierelement und dem ersten Abschnitt zugewandten Enden auf der gegenüber der flachen Seite mit den elektrisch leitenden Streifen anderen flachen Seite seiner beiden flachen Seiten einstückig verbundene, verdickt ausgeführte Andruckstücke auf, die gegenüber den elektrisch kontaktierbaren Bereichen angeordnet sind.The keymat according to the invention then not only has a first section with buttons, but at the same time also has a planar connecting section producing the electrically conductive connection between the first section and an associated printed circuit board and a box-shaped positioning element. In this case, the connecting portion between the first portion and the Fositionierelement is arranged and are the first portion, the flat connecting portion and the positioning member made in one piece of silicone. The connecting portion has on one of its two flat sides electrically conductive strips having electrically contactable areas. The electrically conductive strips extend into the first section and are connected there to contact elements of the buttons. The connecting portion has, at its ends facing the positioning element and the first portion, on the opposite flat side with the electrically conductive strips other flat side of its two flat sides integrally connected, thickened executed Andruckstücke, which are arranged opposite to the electrically contactable areas.
Damit ist eine in der Regel erforderliche und damit ohnehin vorhandene Tastaturmatte lediglich erweitert, erspart aber andere separate Teile für die Herstellung der elektrisch leitenden Verbindung zwischen dem Abschnitt mit den Tasten und der zugehörigen Flachbaugruppe. Gemäß der Erfindung wird somit die Tastaturmatte neben der Verwendung als Tastaturmatte gleichzeitig auch als Verbindungselement für die Verbindung zur zugehörigen Flachbaugruppe genutzt. Mit der Montage der Tastaturmatte erfolgt daher gleichzeitig auch die Montage der elektrisch leitenden Verbindung zwischen der Tastatur und der zugehörigen Flachbaugruppe.Thus, a usually required and therefore already existing keypad is only extended, but saves other separate parts for the production of the electrically conductive connection between the section with the keys and the associated printed circuit board. According to the invention, the keypad is thus used in addition to the use as a keypad simultaneously as a connecting element for the connection to the associated printed circuit board. With the installation of the keyboard mat, therefore, at the same time also the mounting of the electrically conductive connection between the keyboard and the associated printed circuit board.
Eine Tastatur als Ganzes weist neben der Tastaturmatte auch eine Tastaturleiterplatte auf, mit der die Tasten beziehungsweise die Tasten der Tastaturmatte elektrisch und mechanisch in Verbindung stehen. Die Tastaturleiterplatte umfasst dabei in der Regel auch eine Schaltmatrix mit zugehöriger entsprechender Steuerung, durch die nur wenige Ansteuerleitungen für die Ansteuerung der einzelnen Tastenstellen der Tastatur notwendig sind. Beispielsweise genügen für die Ansteuerung von 8, 9 oder 10 Einzeltasten 5 Ansteuerleitungen. Das heißt, die erfindungsgemäße Tastaturmatte braucht nur diese wenigen Ansteuerleitungen zur Verfügung zu stellen.A keyboard as a whole, in addition to the keyboard mat also has a keyboard circuit board, with which the keys or the keys of the keyboard mat are electrically and mechanically in communication. As a rule, the keyboard circuit board also includes a switching matrix with corresponding control, by means of which only a few control lines are necessary for controlling the individual key positions of the keyboard. For example, 5 control lines suffice for the control of 8, 9 or 10 individual keys. That is, the keyboard mat according to the invention needs only to provide these few control lines available.
Da eine Silikon-Tastatur eine hochohmige Kontaktgabe darstellt, ist es in vorteilhafter Weise möglich, eine hochohmige Verbindung von der Tastatur zur Flachbaugruppe zu realisieren. Dies geschieht mittels beispielsweise 5 schmalen Streifen aus leitendem Silikon, welche entsprechende Kontaktpunkte auf der Tastaturleiterplatte mit entsprechenden Kontaktpunkten auf der zugeordneten Flachbaugruppe verbinden und so eine Tastenbetätigung für die Flachbaugruppe kenntlich machen.Since a silicone keyboard represents a high-impedance contact, it is advantageously possible to realize a high-impedance connection from the keyboard to the printed circuit board. This is done by means of, for example, 5 narrow strips of conductive silicone, which connect corresponding contact points on the keyboard circuit board with corresponding contact points on the associated printed circuit board and so make a key operation for the printed circuit board identified.
Der Vorteil der erweiterten Tastaturmatte ist insbesondere, dass keine zusätzlichen Drähte oder Leitfolien benötigt werden. Ebenso sind keine Löt- und/oder Bügelverbindungen notwendig. Auch Steckverbinder sind nicht notwendig.The advantage of the expanded keypad mat is in particular that no additional wires or guide foils are needed. Likewise, no soldering and / or ironing connections are necessary. Also connectors are not necessary.
Ein Tastaturmodul kann komplett vormontiert werden. Es sind daher keine zusätzlichen Arbeitsabläufe wie zum Beispiel Löten, Bügeln oder Stecken notwendig.A keyboard module can be completely pre-assembled. There are therefore no additional operations such as soldering, ironing or plugging necessary.
Weiter vorteilhaft ist, dass zusätzliche Funktionen integrierbar sind. So können beispielsweise flachbaugruppenseitig Lichtleiter genutzt werden. Auch können beispielsweise auf der Flachbaugruppenseite zusätzliche Tasten genutzt werden.It is also advantageous that additional functions can be integrated. For example, flat conductor side light guides can be used. Also, for example, additional buttons can be used on the printed circuit board side.
Bezüglich des elektrischen Geräts wird die Aufgabe erfindungsgemäß durch ein solches elektrisches Gerät gelöst, das die erfindungsgemäße Tastaturmatte integriert hat, wie sie oben mit den zugehörigen Vorteilen näher beschrieben ist.With regard to the electrical device, the object is achieved by such an electrical device that has integrated the keypad according to the invention, as described in more detail above with the associated advantages.
