2) RIASSUNTO 2) SUMMARY

Scopo del presente trovato è la produzione di giunti elettrici in materiale autostringente, composto da tre pareti cilindriche in due pezzi indipendenti, aventi ciascuna parete caratteristiche eletti<1>iche e meccaniche diverse, poi calzando i pezzi uno sull’altro su un supporto cilindrico secondo le necessità, ed applicando sulla superficie esterna del pezzo assemblato una . verr ice conduttiva. The purpose of the present invention is to produce electrical joints in self-tightening material, consisting of three cylindrical walls in two independent pieces, each wall having different elected ical and mechanical characteristics, then fitting the pieces one on top of the other on a cylindrical support according to needs, and applying a. will be conductive.

I giunti autostringen ti attualmente prodotti sono realizzati con l'impiego della coestrusione o costampaggio , per ottenere un manufatto a più strati tecnici ma non scindibili, con funzioni elettriche o meccan iche differenti. The self-tightening joints currently produced are made with the use of coextrusion or co-molding, to obtain a product with several technical but non-separable layers, with different electrical or mechanical functions.

II giunto così pr oldotto è poi espanso ed alloggiato su un supporto rigido, a forma normalmente cilindr ica, con un diametro interno superiore a quello sul quale deve poi essere posizionato il manu: atto stesso. Il preassemblato espanso rimane normalmente in magazzino fino alla vendita e q hindi all’applicazione. The joint thus produced is then expanded and housed on a rigid support, normally cylindrical in shape, with an internal diameter greater than that on which the manual itself must then be positioned. The expanded pre-assembled product normally remains in the warehouse until the sale and then the application.

4) DESCRIZIONE D EL TROVATO 4) DESCRIPTION OF THE FOUND

Nella disegno allega to si riporta una applicazione a puro titolo esemplificativo per meglio descrivere l’invenzi me, essa pertanto non costituisce limitazione per gli sviluppi che possono derivare dalle varie applicazioni che di volta in volta si andranno a realizzare; sviluppi, modifiche e/o aggir nte che si intendono pertanto fin da ora compresi nelle rivendicazioni di cui al presente trovai o. The attached drawing shows an application purely by way of example to better describe the invention, it therefore does not constitute a limitation for the developments that may arise from the various applications that will be implemented from time to time; developments, modifications and / or circumvention which are therefore understood from now on included in the claims referred to herein.

Il tubo interno è reél izzato in una mescola di gomma siliconica o altro elastomero coestruso e/o costampato cor: una mescola di gomma siliconica o altro elastomero addizionata di cariche conduttive (tome ad esempio polvere di carbone) proporzionate in modo da conferire al prodotto la prop lietà elettrica conosciuta come "controllo di campo". Esso si presenta come un unico pez^ o a due strati, come riportato nel disegno con la dicitura tubo interno, dove la parete interrila di spessore S 1,1 è con funzione di controllo di campo, cioè additivata di cariche conduttive, Il diametro interno DI sia ad esempio di 20 mm, lo spessore Sl,l sia ad esempio di 2 mm, 1 spessore Sl,2 sia ad esempio di 3 mm e la lunghezza LI sia ad esempio di 200 mm. The inner tube is reel ized in a mixture of silicone rubber or other coextruded elastomer and / or co-molded with: a mixture of silicone rubber or other elastomer with the addition of conductive fillers (such as carbon powder for example) proportioned in such a way as to give the product the prop liety known as "field control". It is presented as a single piece or in two layers, as shown in the drawing with the wording inner tube, where the inter-row wall of thickness S 1.1 has a field control function, that is, with the addition of conductive charges. is for example 20 mm, the thickness Sl, l is for example 2 mm, 1 thickness Sl, 2 is for example 3 mm and the length L1 is for example 200 mm.

Ή tubo esterno è r elalizzato in sola gomma siliconica o altro elastomero ad elevato potere dielettrico e con “ir emoria elastica” particolarmente esaltata. H diametro interno D2 sia ad esempio di 10 mm, {doè più stretto del tubo interno, lo spessore S2 sia ad esempio di 3 mm e la lunghezza L2 sia ad esempio di 220 mm, cioè più lungo del tubo interno. Sulla superficie esterna del tubo e ^temo è applicata, nel modo più opportuno, una particolare vernice semiconduttiva, per uno spessore finito ad esempio di 0,2 mm, per ottenere l'effetto di "radializzare il camp o elettrico" Ή external tube is made of only silicone rubber or other elastomer with high dielectric power and with particularly enhanced “elastic ir emory”. H internal diameter D2 is for example 10 mm, ie is narrower than the internal tube, the thickness S2 is for example 3 mm and the length L2 is for example 220 mm, ie longer than the internal tube. A particular semiconductive paint, for a finished thickness of 0.2 mm, for example, is applied to the external surface of the tube in the most appropriate way, to obtain the effect of "radializing the electrical field"

H supporto tubolare rigido, realizzato nel modo più vario e nei più vari materiali, ha poi diametro esterno D: ad esempio di 30 mm, cioè più largo del tubo interno, lo spessore S3 quello che si vuole e la lunghezza L3 sia ad esempio di 300 mm, cioè più lungo del tubo esterno. H rigid tubular support, made in the most varied way and in the most various materials, then has an external diameter D: for example 30 mm, i.e. wider than the internal tube, the thickness S3 is what you want and the length L3 is for example of 300 mm, i.e. longer than the outer tube.

Nel processo descritl o nel presente trovato ciascuno strato tubolare componente il manufatto è prodotto singolarme nte con la tecnica più opportuna a conferirgli quelle caratteristiche meccaniche e/o elett iche e/o superficiali e/o altro che si desiderano. In the process described in the present invention, each tubular layer making up the product is produced individually with the most suitable technique to give it those mechanical and / or electrical and / or surface and / or other characteristics that are desired.

Per ottenere il manu atto finito e preassemblato si procederà a calzare consecutivamente l’uno all’altro i vari strati, partendo dal più interno, come si vede nell'assieme in disegno. To obtain the finished and pre-assembled manual, the various layers will be fitted consecutively to each other, starting from the innermost, as seen in the assembly in the drawing.
