Die Klettverbindung der Klettstrukturen, die eine elektrisch leitende Oberfläche aufweisen, zeichnet sich dadurch aus, dass sie als eine biegsame feste elektrische Verbindung geeignet ist.The Velcro connection of the Velcro structures, which have an electrically conductive surface, is characterized in that it is suitable as a flexible solid electrical connection.

Die Klettstrukturen sind in einer Variante aus einem Metalldraht gebildet. Der Flausch kann beispielsweise durch eine Metallwolle gebildet sein.

Die Klettstrukturen umfassen in einer weiteren Variante jeweils eine dünne, biegsame, vorzugsweise elektrisch isolierende Trägerfaser mit einer metallisierten Oberfläche. Die Trägerfasern umfassen in einer vorteilhaften Variante beispielsweise einen Kunststoff. Polymere sind als Material für die Trägerfasern besonders gut geeignet. In Betracht kommen in diesem Zusammenhang beispielsweise Polyethylen, Polyimid (beispielsweise Nylon) und Kapton, das sich durch eine hohe Temperaturbeständigkeit auszeichnet. Auch andere temperaturfeste Materialien sind als Trägerfasern geeignet. Die Trägerfasern können Glas umfassen.In a further variant, the Velcro structures each comprise a thin, flexible, preferably electrically insulating carrier fiber with a metallized surface. The carrier fibers comprise in an advantageous variant, for example, a plastic. Polymers are particularly suitable as material for the carrier fibers. Polyethylene, polyimide (for example nylon) and Kapton, which is distinguished by a high temperature resistance, are suitable in this context. Other temperature-resistant materials are suitable as carrier fibers. The carrier fibers may comprise glass.

Die auf die Trägerfasern aufgebrachte Metallschicht enthält beispielsweise Al, Cu, Ag, Au oder ein anderes Metall. Die Metallschicht umfasst in einer Variante neben den Schichten aus diesen Materialien eine verschleißfeste, vorzugsweise schwer oxidierbare Oberschicht beispielsweise aus Ni.

The metal layer comprises in a variant in addition to the layers of these materials a wear-resistant, preferably Hardly oxidizable upper layer, for example made of Ni. The metal layer is applied, for example, by spraying or in a deposition process (sputtering, etc.).

Das jeweilige Trägerband umfasst ein elektrisch isolierendes Trägersubstrat und eine fest mit diesem verbundene Leiterbahn, die auf das Trägersubstrat vorzugsweise in ein und demselben Verfahrensschritt wie die Metallschicht aufgetragen wird. Die Trägerfasern der Klettstrukturen sind fest mit dem Trägersubstrat verbunden.The respective carrier tape comprises an electrically insulating carrier substrate and a conductor track fixedly connected thereto, which is preferably applied to the carrier substrate in one and the same method step as the metal layer. The carrier fibers of the Velcro structures are firmly connected to the carrier substrate.

Die Leiterbahn ist vorzugsweise als eine elektrische Zuleitung vorgesehen. Sie ist auf einer Oberfläche des Trägersubstrats angeordnet und leitend mit dem Kontaktbereich dieses Trägerbandes verbunden. In einer vorteilhaften Variante können beide Hauptflächen des Trägersubstrats jeweils mindestens eine Leiterbahn aufweisen. Die Leiterbahnen der beiden Hauptflächen sind vorzugsweise über mindestens eine im Trägersubstrat ausgebildete Öffnung, die eine metallisierte Oberfläche aufweist, leitend miteinander verbunden.The conductor track is preferably provided as an electrical supply line. It is arranged on a surface of the carrier substrate and conductively connected to the contact region of this carrier tape. In an advantageous variant, both main surfaces of the carrier substrate may each have at least one conductor track. The conductor tracks of the two main surfaces are preferably conductively connected to one another via at least one opening formed in the carrier substrate, which has a metallized surface.

Auf der Leiterbahn, die als Zuleitung dient, ist vorzugsweise eine Isolationsschicht angeordnet. Diese isoliert die Zuleitung nach außen, was zur Vermeidung von ungewünschten Kurzschlüssen und elektrischem Schlag von Vorteil sein kann.On the conductor track, which serves as a supply line, an insulating layer is preferably arranged. This isolates the supply line to the outside, which can be to avoid unwanted short circuits and electric shock advantage.

Die Leiterbahn ist in einem Zuleitungsbereich des Trägerbands angeordnet, der vorzugsweise auf der Hauptfläche des jeweiligen Trägerbands liegt, auf der auch der Kontaktbereich mit den Klettstrukturen angeordnet ist. Der Zuleitungsbereich ist vorzugsweise frei von den Klettstrukturen.The conductor track is arranged in a feed region of the carrier tape, which preferably lies on the main surface of the respective carrier tape, on which the contact region with the hook and loop structures is also arranged. The supply area is preferably free of the Velcro structures.

Das Trägerband weist in einer Variante mindestens einen Endbereich auf, der frei von den Klettstrukturen und vorzugsweise auch frei von einer Metallisierung ist. Dieser Endbereich dient als Griff für einen Benutzer, was insbesondere für die Trennung der Klettverbindung der Trägerbänder von Vorteil ist.The carrier tape has at least one end region in a variant which is free of the Velcro structures and preferably also free of metallization. This end portion serves as a handle for a user, which is particularly advantageous for the separation of the Velcro connection of the carrier tapes.

Das Trägersubstrat kann neben den ersten Klettstrukturen, die auf seiner ersten Hauptfläche angeordnet sind, auch zweite Klettstrukturen aufweisen, die auf seiner zweiten Hauptfläche angeordnet sind. Die ersten Klettstrukturen bilden vorzugsweise einen Flausch, während die zweiten Klettstrukturen als Haken ausgebildet sind. Es besteht die Möglichkeit, mehr als nur zwei solche Trägerbänder miteinander zu verbinden. Dabei werden die Trägerbänder so übereinander gelegt, dass die ersten und zweiten Klettstrukturen ineinander greifen. Vorzugsweise werden mit Klettstrukturen versehene Bereiche der ersten und zweiten Trägerbänder abwechselnd angeordnet, wobei die Trägerbänder derselben Sorte beispielsweise durch eine gemeinsame Umhüllung oder einen Gurt zu einem Bund miteinander verbunden werden. Die Trägerbänder derselben Sorte sind elektrisch parallel zueinander verbunden, wobei sie vorzugsweise an einen gemeinsamen elektrischen Anschluss angeschlossen werden. Durch die Verbindung einer Vielzahl von Trägerbändern gelingt es, eine Stromtragfähigkeit der elektrisch leitenden Klettverbindung zu erhöhen.The carrier substrate may, in addition to the first Velcro structures, which are arranged on its first main surface, also have second Velcro structures, which are arranged on its second major surface. The first Velcro structures preferably form a loop, while the second Velcro structures are formed as hooks. It is possible to connect more than just two such carrier bands with each other. In this case, the carrier tapes are superimposed so that the first and second Velcro structures interlock. Preferably, regions of the first and second carrier tapes provided with hook-and-loop structures are arranged alternately, wherein the carrier tapes of the same type are connected to form a waistband, for example, by a common cover or a belt. The carrier tapes of the same type are electrically connected in parallel with each other, wherein they are preferably connected to a common electrical connection. By connecting a plurality of carrier tapes, it is possible to increase a current carrying capacity of the electrically conductive Velcro connection.

Das elektrische Kontaktelement, das eine elektrisch leitfähige Klettverbindung umfasst, wird nun anhand von schematischen und nicht maßstabgetreuen Figuren erläutert. Es zeigen:

  • Figur 1 im Querschnitt eine Klettverbindung mit ineinander greifenden elektrisch leitfähigen Klettstrukturen von zwei Trägerbändern;
  • Figur 2 im Querschnitt eine Klettverbindung, die eine Vielzahl von Trägerbändern aufweist, die auf beiden Oberflächen Klettstrukturen aufweisen.
The electrical contact element, which comprises an electrically conductive Velcro connection, will now be explained with reference to schematic and not to scale figures. Show it:
  • Figure 1 in cross-section a Velcro connection with interlocking electrically conductive Velcro structures of two carrier bands;
  • Figure 2 in cross-section a hook and loop fastener comprising a plurality of carrier tapes having Velcro on both surfaces.

In Figur 1 ist eine Klettverbindung gezeigt, die ein erstes Trägerband 1 und ein zweites Trägerband 2 umfasst. Das erste Trägerband 1 umfasst ein flexibles erstes Trägersubstrat 11 und das zweite Trägerband 2 ein flexibles zweites Trägersubstrat 21. Das erste Trägerband 1 weist einen ersten Kontaktbereich 12 mit ersten Klettstrukturen 14 und das zweite Trägerband 2 einen zweiten Kontaktbereich 22 mit zweiten Klettstrukturen 24 auf. Die Klettstrukturen 14, 24 der beiden Trägerbänder sind komplementär zueinander - als Schlaufen und Haken - ausgebildet und greifen ineinander. Die ersten Klettstrukturen 14 sind mit dem Trägersubstrat 11 des ersten Trägerbands 1 und die zweiten Klettstrukturen 24 mit dem Trägersubstrat 21 des zweiten Trägerbands 2 fest verbunden, auch wenn die Klettverbindung getrennt wird.FIG. 1 shows a Velcro connection comprising a first carrier tape 1 and a second carrier tape 2. The first carrier tape 1 comprises a flexible first carrier substrate 11 and the second carrier tape 2 a flexible second carrier substrate 21. The first carrier tape 1 has a first contact region 12 with first Velcro structures 14 and the second carrier tape 2 has a second contact region 22 with second Velcro structures 24. The Velcro structures 14, 24 of the two carrier bands are complementary to each other - as loops and hooks - formed and interlock. The first Velcro structures 14 are fixedly connected to the carrier substrate 11 of the first carrier tape 1 and the second Velcro structures 24 to the carrier substrate 21 of the second carrier tape 2, even if the Velcro connection is disconnected.

An der Oberfläche des jeweiligen Trägersubstrats sind Leiterbahnen 15, 25 angeordnet, die mit dem Kontaktbereich 12, 22 elektrisch leitend verbunden sind. Die Leiterbahnen sind hier auf beiden Hauptflächen des Trägersubstrates angeordnet. Die Leiterbahnen der beiden Hauptflächen sind über mindestens eine im Trägersubstrat ausgebildete Durchkontaktierung 16, 26 leitend miteinander verbunden. Die Durchkontaktierung kann beispielsweise durch eine im Trägersubstrat ausgebildete Öffnung mit einer metallisierten Oberfläche gebildet sein. Die Öffnung kann aber auch mit einem elektrisch leitfähigen Material zumindest teilweise ausgefüllt sein.On the surface of the respective carrier substrate conductor tracks 15, 25 are arranged, which are electrically conductively connected to the contact region 12, 22. The conductor tracks are arranged here on both main surfaces of the carrier substrate. The conductor tracks of the two main surfaces are conductively connected to one another via at least one through-connection 16, 26 formed in the carrier substrate. The via can be formed, for example, by an opening formed in the carrier substrate with a metallized surface. The opening can also be at least partially filled with an electrically conductive material.

Auf die Metallisierung auf der nach außen gewandten Seite des Trägerbandes kann unter Umständen verzichtet werden. Falls durch das Band durchkontaktiert wird, ist es möglich, auf die Metallisierung auf der nach innen gewandten Seite des Trägerbandes verzichtet werden.On the metallization on the outwardly facing side of the carrier tape may be waived under certain circumstances. If through-contacted by the tape, it is possible to dispense with the metallization on the inwardly facing side of the carrier tape.

Jedes Trägerband 11, 21 kann mindestens eine innen liegende Leiterbahn aufweisen, die parallel zu den Leiterbahnen 15 bzw. 25 geschaltet und auch mit der Durchkontaktierung 16 bzw. 26 leitend verbunden ist. Eine parallele Verschaltung von Leiterbahnen hat den Vorteil einer hohen Stromtragfähigkeit. Dadurch gelingt es, in der Kontaktanordnung mit der Klettverbindung Ströme über 1 A zu führen.Each carrier tape 11, 21 may have at least one inner conductor track, which is connected in parallel to the conductor tracks 15 and 25 and is also conductively connected to the through-connection 16 or 26. A parallel interconnection of printed conductors has the advantage of a high current carrying capacity. This makes it possible to lead in the contact arrangement with the Velcro connection currents above 1 A.

Das jeweilige Trägerband 1, 2 umfasst einen Endbereich 13, 23, der frei von Klettstrukturen ist. Der Endbereich 13, 23 ist vorzugsweise metallisierungsfrei und als Griff für einen Benutzer zur Trennung der Klettverbindung vorgesehen.The respective carrier tape 1, 2 comprises an end region 13, 23 which is free of Velcro structures. The end portion 13, 23 is preferably metallization-free and provided as a handle for a user to separate the Velcro connection.

Vorzugsweise weist nur ein als Kontaktbereich vorgesehener Bereich des jeweiligen Trägerbandes die Klettstrukturen auf, wobei seine übrigen Bereiche frei von Klettstrukturen sind.Preferably, only one region of the respective carrier strip provided as a contact region has the hook-and-loop structures, with its remaining regions being free from hook-and-loop structures.

In Figur 2 ist eine Klettverbindung gezeigt, die eine Vielzahl von ersten Trägerbändern 1 sowie eine Vielzahl von zweiten Trägerbändern 2 aufweist, die jeweils auf beiden Oberflächen Klettstrukturen aufweisen. Beispielsweise sind schlaufenartige Klettstrukturen auf der ersten Hauptfläche und hakenartige Klettstrukturen auf der zweiten Hauptfläche des jeweiligen ersten (oder zweiten) Trägerbands angeordnet.FIG. 2 shows a Velcro connection which has a plurality of first carrier tapes 1 and a multiplicity of second carrier tapes 2, which each have hook-and-loop structures on both surfaces. For example, loop-type Velcro structures on the first main surface and hook-like Velcro structures are arranged on the second main surface of the respective first (or second) carrier tape.

Es ist vorteilhaft, wenn die endständigen Trägerbänder auf ihrer nach außen gewandten Oberfläche keine Klettstrukturen aufweisen.It is advantageous if the terminal carrier tapes have no Velcro structures on their outwardly facing surface.

Die Trägerbänder ein und derselben Sorte sind vorzugsweise - beispielsweise mittels eines Gurtes oder einer Umhüllung - zu einem Bund zusammengefasst.The carrier tapes of one and the same type are preferably combined - for example by means of a belt or an envelope - to form a waistband.
