Description

Bildanzeigeeinrichtung mit Leiterplatinen und Haltedrähten  Image display device with printed circuit boards and holding wires
[Ol ] Die Erfindung betrifft eine Bildanzeigeeinrichtung mit länglichen Leiterplatinen, die nebeneinander mehrere Leuchtpunkte aufweisen, und quer dazu angeordnete Haltedrähte. [02] Aus der WO 2009/01 1853 und der EP 1 888 966 Bl ist es bekannt, längliche Leiterplatinen innerhalb von Drahtstrukturen anzuordnen. Hierzu werden die Leiterplatinen in Schutzhüllen in ein Drahtgewebe eingearbeitet, sodass sie fest mit dem Drahtgewebe in Verbindung stehen. Für Revisionszwecke wird die Leiterplatine aus der Umhüllung herausgezogen. Dieser Aufbau ermöglicht es, große Bildanzeigeeinrichtungen herzustellen, die an Außenfassaden von Gebäuden befestigt werden können. The invention relates to an image display device with elongated printed circuit boards, which have a plurality of luminous dots side by side, and holding wires arranged transversely thereto. [02] From WO 2009/01 1853 and EP 1 888 966 Bl it is known to arrange elongate printed circuit boards within wire structures. For this purpose, the printed circuit boards are incorporated in protective sheaths in a wire mesh, so that they are firmly connected to the wire mesh. For inspection purposes, the printed circuit board is pulled out of the enclosure. This structure makes it possible to produce large image display devices that can be attached to the exterior facades of buildings.
[03] Ausgehend von derartigen Bildanzeigeeinrichtungen mit länglichen Leiterplatinen und quer dazu angeordneten Haltedrähten liegt der Erfindung die Aufgabe zugrunde, den Aufbau zu vereinfachen, um die gesamte Anordnung leichter herstellen zu können. [04] Diese Aufgabe wird mit einer gattungsgemäßen Bildanzeigeeinrichtung gelöst, bei der die Leiterplatinen an den Haltedrähten befestigt sind und eine stromleitende Verbindung zu den Haltedrähten aufweisen, um die Leiterplatinen mit Strom zu versorgen. Starting from such image display devices with elongated printed circuit boards and transverse thereto arranged holding wires, the invention has for its object to simplify the structure in order to make the entire arrangement easier. [04] This object is achieved with a generic image display device in which the printed circuit boards are fastened to the holding wires and have a current-conducting connection to the holding wires in order to supply the printed circuit boards with power.
[05] Die Leiterplatinen sind somit einerseits an den Haltedrähten befestigt und ande- rerseits weisen die Leiterplatinen eine stromleitende Verbindung zu den Haltedrähten auf, um die Leiterplatinen mit Strom zu versorgen. Somit werden quer zu den Leiterplatinen angeordnete Drähte als Haltedrähte als Drähte für die Stromversorgung der Leiterplatinen verwendet. Die Haltedrähte haben somit eine Doppelfunktion. Einerseits dienen sie dazu, die Leiterplatinen stabil zu halten und andererseits dienen sie dazu, die Leiterplatinen mit Strom zu versorgen. [05] The printed circuit boards are thus fastened on the one hand to the holding wires and on the other hand the printed circuit boards have a current-conducting connection to the holding wires in order to supply the printed circuit boards with current. Thus, wires arranged transversely to the printed circuit boards are used as holding wires as wires for the power supply of the printed circuit boards. The holding wires thus have a double function. On the one hand they serve to keep the printed circuit boards stable and on the other hand they serve to supply the printed circuit boards with electricity.
|Bestätigungskopie| [06] Um beispielsweise für Revisionszwecke einzelne Leiterplatinen von den Haltedrähten zu entfernen, wird vorgeschlagen, dass die Leiterplatinen lösbar an den Haltedrähten befestigt sind. Hierdurch wird auch der Aufbau der Bildanzeigeeinrichtung erleichtert, da zunächst die Haltedrähte angeordnet werden können und anschließend können die Leiterplatinen an den Haltedrähten lösbar befestigt werden. Entsprechend wird auch der Abbau einer derartigen Bildanzeigeeinrichtung erleichtert, sodass die Bildanzeigeeinrichtung leicht transportabel auch nur für kurze Zeit an einem bestimmten Ort aufgestellt oder montiert werden kann. | Confirmation copy | [06] For example, to remove individual printed circuit boards from the holding wires for inspection purposes, it is proposed that the printed circuit boards be detachably fastened to the holding wires. As a result, the structure of the image display device is facilitated, since first the retaining wires can be arranged and then the printed circuit boards can be releasably attached to the retaining wires. Accordingly, the degradation of such an image display device is facilitated, so that the image display device can be placed or mounted easily transportable even for a short time at a specific location.
[07] Die Haltedrähte können zusätzlich zu ihrer Funktion der Stromversorgung auch die Funktion der Dateneinspeisung übernehmen. Hierzu können die gleichen Haltedrähte oder zusätzliche Haltedrähte verwendet werden. [07] In addition to their function of power supply, the holding wires can also take on the function of data feed. For this purpose, the same retaining wires or additional retaining wires can be used.
[08] Die Leiterpatinen werden über die Haltedrähte mit Strom versorgt. Die Information, welche Leuchtpunkte mit Strom versorgt werden sollen, erhalten die Platinen über einen gesonderten Anschluss oder über die Haltedrähte. Dafür kann - wie bei einer W- LAN- oder IP-Steckdose im selben Haltedraht ein Grundstrom für die Stromversorgung fließen und darauf moduliert ein Spannungsprofil, das von der Platine ausgelesen werden kann, um dementsprechend die Leuchtpunkte anzusteuern. Dies wird auch unter Powerlan angeboten und ermöglicht es, auf eine separate Dateneinspeisung zu verzichten. [09] Eine andere Ausführungsvariante sieht vor, dass die Leiterplatinen eine aufgesteckte Dateneinspeisung aufweisen. Diese Dateneinspeisung kann stirnseitig oder seitlich auf mehrere Leiterplatinen aufgesteckt werden, um die Platine mit Informationen darüber zu versorgen, welche Leuchtpunkte wann mit Strom versorgt werden sollen. [08] The conductor leads are powered by the holding wires. The information about which luminous points should be supplied with power, the boards receive a separate connection or via the holding wires. This can - as in a W-LAN or IP socket in the same holding wire flow a base current for the power supply and modulated on a voltage profile that can be read from the board to accordingly control the light points. This is also offered under Powerlan and makes it possible to dispense with a separate data feed. [09] Another embodiment provides that the printed circuit boards have a plugged-in data feed. This data feed can be plugged on the front side or laterally on several printed circuit boards in order to provide the board with information about which luminous points should be supplied with power.
[10] Ein besonders kompakter Aufbau wird dadurch erzielt, dass die Leiterplatinen auf ihrer Längserstreckung mehrere Ausnehmungen zur Aufnahme von Haltedrähten aufweisen. Dadurch können die Haltedrähte in der Ebene der Leiterplatine geführt werden. Somit wird einerseits die Tiefe der Bildanzeigeeinrichtung verkleinert und anderer- seits wird vermieden, dass die Haltedrähte in die Blickachse zwischen Betrachter und Leuchtpunkt gelangen. Die Haltedrähte können dabei soweit in die Ebene der Leiterplatinen gerückt werden, dass die Leuchtpunkte am Rand einer Leiterplatine aus der Ebene der Platine und der Haltedrähte vorstehen. [1 1 ] Eine einfache Art der Befestigung wird dadurch erzielt, dass zwischen den länglichen Leiterplatinen und den Haltedrähten Kontaktfedern zur Befestigung angeordnet sind. Dies ermöglicht eine schnappende oder rastende, vorzugsweise lösbare, Befestigung mittels Kontaktfedern, die beispielsweise mittels zwei gebogenen Schenkeln den Haltedraht oder die Platine halten. [12] Die Kontaktfedern können beispielsweise fest mit den Haltedrähten verbunden sein und lösbar die Platine halten. Eine vorteilhafte Ausftihrungsvariante sieht jedoch vor, dass die Kontaktfedern mit der Leiterplatine unlösbar verbunden sind und an den Haltedrähten angesteckt sind. Hierzu können die Kontaktfedern auf der Platine verlötet sein. Ein einfaches Stanz-Biege-Teil, beispielsweise aus Kupfer, ermöglicht an der Pla- tine eine gelötete Befestigung und eine klammernde Befestigung am Haltedraht. A particularly compact construction is achieved in that the printed circuit boards have on their longitudinal extent a plurality of recesses for receiving retaining wires. As a result, the holding wires can be guided in the plane of the printed circuit board. Thus, on the one hand, the depth of the image display device is reduced and, on the other hand, it is avoided that the retaining wires get into the line of sight between the observer and the illuminated spot. The retaining wires can be moved so far into the plane of the printed circuit boards, that project the luminous dots on the edge of a printed circuit board from the plane of the board and the holding wires. [1 1] A simple type of attachment is achieved by arranging contact springs for attachment between the elongated printed circuit boards and the retaining wires. This allows a snapping or latching, preferably releasable, attachment by means of contact springs that hold the retaining wire or the board, for example by means of two curved legs. [12] The contact springs may for example be firmly connected to the holding wires and releasably hold the board. An advantageous Ausftihrungsvariante provides, however, that the contact springs are permanently connected to the circuit board and are plugged into the holding wires. For this purpose, the contact springs can be soldered on the board. A simple stamped and bent part, made of copper, for example, allows the board to have a soldered attachment and a clamped attachment to the retaining wire.
[13] Um eine leitende Verbindung vom Haltedraht über die Kontaktfeder zur Platine zu ermöglichen, kann der Haltedraht zumindest an der Anlagefläche zur Kontaktfeder stromleitend sein. Sofern jedoch isolierte Haltedrähte verwendet werden, wird vorgeschlagen, dass die Haltedrähte Kontakthülsen aufweisen. Die Kontakthülsen bilden dann einen Übergang zwischen dem leitenden Haltedraht und der Kontaktfeder bzw. der Platine. [13] In order to enable a conductive connection from the retaining wire via the contact spring to the board, the retaining wire may be at least on the contact surface to the contact spring current conducting. However, if insulated retaining wires are used, it is proposed that the retaining wires have contact sleeves. The contact sleeves then form a transition between the conductive holding wire and the contact spring or the board.
[14] Eine bevorzugte Ausführungsvariante sieht vor, dass die Kontakthülsen einen Dorn und der Haltedraht eine Isolation aufweisen. Der Dorn durchsticht bei der Verbindung von Kontakthülse und Haltedraht die Isolierung des Haltedrahtes. Dies ermöglicht es, auch isolierte Haltedrähte zu verwenden und auf diesen isolierten Haltedrähten in regelmäßigen Abständen Kontakthülsen aufzupressen oder aufzucrimpen. Derartige Kontakthülsen können wie die Kontaktfedern als Stanz-Biege-Teil einfach hergestellt werden. Bei der Befestigung der Kontakthülse am isolierten Haltedraht durchsticht der Dorn der Kontakthülse die Isolation und bildet eine stromleitende Verbindung von der Seele des Haltedrahtes zur Kontakthülse. Die Kontakthülse bildet beim Anstecken der Leiterplatine eine definierte Oberfläche, die einen stromleitenden Übergang zwischen Kontakthülse und Kontaktfeder erleichtert. [14] A preferred embodiment provides that the contact sleeves have a mandrel and the retaining wire an insulation. The mandrel punctures the insulation of the retaining wire when connecting the contact sleeve and retaining wire. This makes it possible to use insulated retaining wires and squeeze or crimp on this insulated retaining wires at regular intervals contact sleeves. Such contact sleeves can be easily manufactured as the contact springs as a stamped and bent part become. When mounting the contact sleeve on the insulated retaining wire, the mandrel of the contact sleeve pierces the insulation and forms a current-conducting connection from the soul of the retaining wire to the contact sleeve. When the printed circuit board is plugged in, the contact sleeve forms a defined surface which facilitates a current-conducting transition between contact sleeve and contact spring.
[15] Die Haltedrähte, an denen die Leiterplatinen befestigt sind, können einzelne, vorzugweise parallel verlaufende, blanke oder isolierte, stromleitende Drähte sein. Zur Erhöhung der Stabilität kann die Bildanzeigeeinrichtung ein Flächengefüge aus Drähten aufweisen. Vorteilhaft ist es dabei, wenn die Haltedrähte Teil dieses Flächengefüges sind. The retaining wires to which the printed circuit boards are attached may be single, preferably parallel, bare or insulated, electrically conductive wires. To increase the stability, the image display device may have a surface structure of wires. It is advantageous if the retaining wires are part of this surface structure.
[16] Dieses Flächengefüge kann ein Gestrick, Gewirk oder Vlies oder auch ein Geflecht aus beliebigen Materialien, wie beispielsweise auch Kunststoff oder Naturmaterialien, sein. Besonders vorteilhaft ist ein Drahtgewebe als Flächengefüge und im Hinblick auf Stabilität und elektrische Leiteigenschaften wird vorzugsweise ein Drahtge- webe aus Metall eingesetzt oder ein Gewebe, das unter anderem auch Metalldrähte aufweist. This surface structure may be a knitted fabric, knitted or nonwoven or a mesh of any materials, such as plastic or natural materials. A wire mesh is particularly advantageous as a surface structure, and with regard to stability and electrical conduction properties, it is preferable to use a wire mesh made of metal or a woven fabric which, inter alia, also comprises metal wires.
[17] Ein Ausfuhrungsbeispiel einer Bildanzeigeeinrichtung ist in der Zeichnung dargestellt und wird im Folgenden näher erläutert. Es zeigt [17] An exemplary embodiment of an image display device is shown in the drawing and will be explained in more detail below. It shows

Quer zu den Leiterplatinen 2 bis 5 sind Haltedrähte 20 und 21 angeordnet, an denen die Leiterplatinen 2 bis 5 befestigt sind. Zwischen den Leiterplatinen 2 bis 5 und den Haltedrähten 21, 22 sind jeweils stromleitende Verbindungen 22 bis 27 vorgesehen. [18] The image display device 1 shown in FIG. 1 has a plurality of elongated printed circuit boards 2, 3, 4, 5, each of which has a plurality of luminous dots 6 to 19 next to each other. Transverse wires 20 and 21, to which the printed circuit boards 2 to 5 are attached, are arranged transversely to the printed circuit boards 2 to 5.

[19] Die Figur 2 zeigt eine als Stanz- oder Biegeteil hergestellte Kontaktfeder 28 aus Kupfer oder einem anderen gut leitenden Material. Diese Kontaktfeder 28 hat einen Spalt 29, mit dem die Kontaktfeder 28 auf eine Platine 2 aufgesteckt werden kann. Zur Befestigung der Kontaktfeder 28 an der Platine 2 ist an der Platine 2 ein beidseitig durchkontaktiertes Löt-Pad 30 vorgesehen.

[20] Die Kontaktfeder 28 hat neben dem Spalt 29 eine sich quer zum Spalt 29 erstreckende Aufnahme 31 für einen Haltedraht 20, 21.

FIG. 2 shows a contact spring 28 made of copper or another highly conductive material, produced as a stamped or bent part. This contact spring 28 has a gap 29, with which the contact spring 28 can be plugged onto a circuit board 2. To attach the contact spring 28 to the board 2, a solder pad 30, which is plated on both sides, is provided on the board 2. This makes it possible to solder the contact spring 28 as shown in Figure 6 on the board 2 on the solder pad 30. The contact spring 28 has, in addition to the gap 29, a receptacle 31 extending transversely to the gap 29 for a retaining wire 20, 21. In order to arrange this receptacle in the area of the board 2, the board 2 has a plurality of recesses 32 on its longitudinal extent. Herein, the holding wires can be arranged.
[21 ] An der Platine 2 sind als Leuchtpunkte 6 bis 19 RGB-SMD-LEDs vorgesehen, die individuell angesteuert werden können. Hierfür weist jede Leiterplatine mindestens eine aufgesteckte Dateneinspeisung 33 auf. Diese Dateneinspeisung 33 besteht aus einer zu den Platinen 2 bis 5 quer verlaufenden Einspeisplatine 34 mit mehreren Buchsen 35, 36, 37, die mit Steckern 38, 39, 40 an den Platinen 2 bis 5 zusammenwirken können. Diese Einspeisplatine 34 kann entweder seitlich oder stirnseitig auf die Leiterplatinen 2 bis 5 aufgesteckt werden. Selbstverständlich können auch an der Einspeisplatine 34 die Stecker vorgesehen werden, während die Platinen 2 bis 5 entsprechende Buchsen aufweisen. On the board 2 6 to 19 RGB SMD LEDs are provided as luminous points, which can be controlled individually. For this purpose, each printed circuit board on at least one plugged data feed 33. This data feed 33 consists of a to the boards 2 to 5 transverse feeder board 34 with a plurality of sockets 35, 36, 37, which can cooperate with plugs 38, 39, 40 on the boards 2 to 5. This feeder board 34 can be attached either laterally or frontally on the printed circuit boards 2 to 5. Of course, also on the feed board 34, the Plugs are provided while the boards have 2 to 5 corresponding sockets.
[22] Die Figur 5 zeigt exemplarisch einen Abschnitt eines Haltedrahtes 20 mit einer Kontakthülse 41. Auf diese Kontakthülse 41 kann die Kontaktfeder 28 mit der daran angelöteten Leiterplatine 2 aufgesteckt werden. Hierfür hat die Kontaktfeder 28 zwei Arme 42, 43, die elastisch schnappend die Kontakthülse 41 umgreifen. Hierdurch wird ein elektrischer Kontakt geschlossen, der von der Leiterplatine 2 über das Löt-Pad 30 und die Arme 42 und 43 der Kontaktfeder 28 zur Kontakthülse 41 verläuft. FIG. 5 shows by way of example a section of a holding wire 20 with a contact sleeve 41. The contact spring 28 with the printed circuit board 2 soldered thereto can be plugged onto this contact sleeve 41. For this purpose, the contact spring 28 has two arms 42, 43 which engage around the contact sleeve 41 elastically snapping. As a result, an electrical contact is closed, which extends from the printed circuit board 2 via the solder pad 30 and the arms 42 and 43 of the contact spring 28 to the contact sleeve 41.
[23] Die Kontakthülse 41 besteht zunächst aus einem u-fÖrmig gebogenen Grundkör- per 44 mit zwei Dornen 45 und 46. Der Haltedraht 20 besteht aus einer den Draht (nicht gezeigt) umhüllenden Isolierung 47. Auf diese Isolierung 47 wird die u-förmig gebogene Kontakthülse 41 derart aufgesteckt, dass sich die Dornen 45, 46 der Kontakthülse 41 durch die Isolierung 47 in die Drahtseele des Haltedrahtes 20 bohren. Danach wird die Kontakthülse 41 derart um die Isolierung des Haltedrahtes 20 gelegt, dass sie eine im Querschnitt kreisrunde Form einnimmt. [23] The contact sleeve 41 initially consists of a U-shaped base body 44 with two spikes 45 and 46. The retaining wire 20 consists of an insulation 47 surrounding the wire (not shown). This insulation 47 becomes U-shaped curved contact sleeve 41 plugged in such a way that the spikes 45, 46 of the contact sleeve 41 through the insulation 47 in the wire core of the retaining wire 20 drill. Thereafter, the contact sleeve 41 is placed around the insulation of the holding wire 20 so that it assumes a circular cross-sectional shape.
