Ploski gibki električni vodnikFlat flexible electrical conductor

Predlagani izum se nanaša na ploski gibki električni vodnik, obsegajoč tanko elastično podlago in na njej razporejen tanek električni vodnik.The present invention relates to a flat flexible electrical conductor comprising a thin elastic base and a thin electrical conductor arranged thereon.

Ploski gibki električni vodnik je razkrit na primer z objavo mednarodne patentne prijave štev. WO 2006/116677 A2. Znani vodnik obsega elastično podlago, konkretno iz Kaptona, na kateri so izdelane sledi iz prevodne tinte, konkretno iz tinte na osnovi ogljika. Vendar ta znana rešitev ne izpolnjuje sočasnih zahtev po veliki dolžini, na primer nad 1 m, elastičnosti in majhni masi vodnika.A flat flexible electrical conductor is disclosed, for example, by the publication of international patent application no. WO 2006/116677 A2. The well-known guide comprises an elastic base, specifically from Kapton, on which traces are made of conductive ink, specifically carbon-based ink. However, this known solution does not meet the concomitant requirements of large lengths, such as over 1 m, elasticity and low conductor mass.

Naloga predlaganega izuma je ustvariti ploski gibki električni vodnik uvodoma navedene vrste, s katerim so odpravljene pomanjkljivosti znanih rešitev.It is an object of the present invention to provide a flat flexible electrical conductor of the type mentioned above, which eliminates the disadvantages of the known solutions.

Zastavljena naloga je rešena z značilnostmi, podanimi v značilnostem delu 1. patentnega zahtevka. Podrobnosti izuma so razkrite v podzahtevkih.The assigned task is solved by the characteristics given in the characteristic of claim 1. Details of the invention are disclosed in the sub-claims.

Izum je v nadaljevanju podrobneje opisan na osnovi neomejujočega izvedbenega primera in s sklicevanjem na priloženo skico, kjer kaže sl. 1 ploski gibki električni vodnik po izumu v tridimenzionalnem pogledu, sl. 2 drugi izvedbeni primer ploskega gibkega električnega vodnika s sl. 1.The invention will now be described in more detail with reference to a non-limiting embodiment and with reference to the accompanying drawing, where FIG. 1 shows a flat flexible electrical conductor of the invention in three-dimensional view; 2 is another embodiment of a flat flexible electrical conductor of FIG. 1.

Ploski gibki električni vodnik A po izumu obsega nosilno plast 1 in na njej razporejeno električno prevodno plast 2, katere proč od nosilne plasti 1 obrnjena stran je prekrita z zaščitno plastjo 3. Pri tem je omenjena nosilna plast 1 zasnovana kot elastična trakasta podlaga, na primer poliimidni film (Kaptori), in je na njej razporejena električno prevodna plast 2 izbrana kot kovinska plast, prednostno iz aluminija, in je proč od nosilne plasti 1 obrnjena stran omenjene električno prevodne plasti 2 prekrita z zaščitno plastjo 3, na primer iz umetne snovi. Omenjene plasti 1, 2, 3 so medsebojno spojene na primer po postopku laminiranja. Tako zasnovani električni vodnik A je na svojem vsakokratnem prostem koncu zasnovan z območjem 5, 6, ki je prosto zaščitne plasti 3 in je namenjeno namestitvi konektorja ali nadaljnji električni povezavi. Da se v omenjenem območju 5, 6 vodnika A omogoči karseda dober spoj prevodne plasti 2 z na primer konektorjem, je omenjena prevodna plast 2 vsaj v tem območju 5, 6 prevlečena z materialom, ki se s konektorjem spaja bolje kot prevodna plast 2. Ena od možnosti predvideva galvanski nanos prevleke iz kositra na prevodno plast 2 iz aluminija.The flat flexible electrical conductor A of the invention comprises a support layer 1 and an electrically conductive layer 2 disposed thereon, the side of which is facing away from the support layer 1 and is covered by a protective layer 3. In this case, said support layer 1 is designed as an elastic strip base, for example polyimide film (captors), and having an electrically conductive layer 2 arranged therein is selected as a metal layer, preferably aluminum, and away from the support layer 1, the facing side of said electrically conductive layer 2 is covered with a protective layer 3, for example plastic. Said layers 1, 2, 3 are interconnected, for example, by a laminating process. The electrical conductor A thus designed is, at its respective free end, designed with an area 5, 6 which is free of the protective layer 3 and is intended to accommodate the connector or further electrical connection. In order to allow a good connection of conductive layer 2 with, for example, a connector in said region 5, 6 of conductor A, said conductive layer 2 is at least in this region 5, 6 coated with a material which fits better with the connector than conductive layer 2. One the galvanic coating of the tin coating onto the conductive layer 2 of aluminum is preferably provided.

Nadalje se da niz omenjenih gibkih električnih vodnikov A, vsakokrat obsegajočih nosilno plast 1, prevodno plast 2 in zaščitno plast 3, po izumu sestaviti na način, da se jih razporedi drugega na drugega, pri čemer je med dvema sosednjima vodnikoma A razporejena plast 4 adhezijskega sredstva. Vsakokratna sosednja vodnika A sta s pomočjo omenjene plasti 4 adhezijskega sredstva spojena po postopku laminiranja. Seveda je v primeru omenjenega sestavljanja vodnikov A izbiroma mogoče, da je omenjena zaščitna plast 3 odsotna pri vsem vodnikih A v nizu in je prisotna le na najbolj zunanjem od vodnikov A, ki se jih sestavlja v omenjeni niz. Dalje je po predlaganem izumu predvideno, da je vsaj ena omenjena prevodna plast 2 izbiroma razdeljena v več medsebojno vzporednih in električno ločenih odsekov 2', na primer po postopku jedkanja. Tako zasnovani niz električnih vodnikov je zasnovan na način, da je vsakokratni spodnji vodnik A daljši od zgornjega vodnika A, s čimer je omogočeno, da se v območju 5, 6 vsakokratnega vodnika A na njegovem vsakokratnem prostem koncu lahko priključi konektor ali olajša nadaljnjo električno povezavo.Further, a series of said flexible electrical conductors A, each comprising a carrier layer 1, a conductive layer 2 and a protective layer 3, can be assembled according to the invention in such a way that they are arranged on top of one another, with an adhesion layer 4 arranged between two adjacent conductors A. funds. The adjacent conductors A are connected by means of said adhesive layer 4 through a laminating process. Of course, in the case of said assembly of conductors A, it is optionally possible that said protective layer 3 is absent for all conductors A in the array and is present only at the outermost of the conductors A assembled into said array. Further, it is contemplated by the present invention that at least one said conductive layer 2 is optionally divided into several parallel and electrically separated sections 2 ', for example, by an etching process. Such a series of electrical conductors is designed in such a way that each of the lower conductors A is longer than the upper conductor A, thereby enabling a connector at its respective free end to be able to attach a connector at its respective free end or facilitate further electrical connection. .

Ploski gibki električni vodnik po izumu na zgoraj opisan način omogoča visoko polnilno razmerje med prevodno plastjo 2 in izolacijsko plastjo 1, 4, 3.The flat flexible electrical conductor of the invention provides a high charge ratio between conductive layer 2 and insulating layer 1, 4, 3 as described above.
