"Connettore per il collegamento elettrico fra una saldatrice e gli spinotti di raccordo dei manicotti di polietilene atti a venire saldati mediante elettrofusione su tubi o simili" "Connector for the electrical connection between a welding machine and the connecting pins of the polyethylene sleeves suitable for being welded by electrofusion on pipes or the like"

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

Nel campo degli impianti di convogliamento di fluidi, quali acqua, gas o simili, Ã ̈ noto l'impiego di tubi in materia plastica saldabili, quali ad esempio i tubi in polietilene. E' anche noto di impiegare, per la saldatura di tali tubi fra loro (o con altri elementi di impianto), dei manicotti ad In the field of systems for conveying fluids, such as water, gas or the like, the use of weldable plastic pipes, such as for example polyethylene pipes, is known. It is also known to use, for the welding of these pipes together (or with other system elements),

elettro fusione, muniti di spinotti elettrici collegabili ad adatte macchine saldatrici elettriche. electro fusion, equipped with electric pins that can be connected to suitable electric welding machines.

Un problema di tali dispositivi di saldatura consiste nel fatto che detti spinotti di raccordo elettrico presentano dei pin di misure differenti, ed in particolare di 4 mm e di 4,7 mm. A problem of these welding devices consists in the fact that said electrical connecting pins have pins of different sizes, and in particular of 4 mm and 4.7 mm.

Questo fatto implica che ciascuna macchina saldatrice deve essere munita di cavi elettrici muniti di terminali di diametri differenti o deve essere munita di adattatori per adattare i terminali agli spinotti di diametro 4,7 mm o agli spinotti di diametro 4 mm. This fact implies that each welding machine must be equipped with electric cables equipped with terminals of different diameters or must be equipped with adapters to adapt the terminals to the 4.7 mm diameter pins or the 4 mm diameter pins.

Tutto ciò comporta numerosi inconvenienti, sia dal punto di vista delle attrezzature richieste che dal punto di vista che l'uso di adattatori in cantiere non à ̈ sempre consigliato e consigliabile. All this involves numerous drawbacks, both from the point of view of the required equipment and from the point of view that the use of adapters on site is not always recommended and advisable.

Per ovviare a questo problema à ̈ stato proposto con la domanda di brevetto GE 2006 A 000035 l'adozione di un dispositivo unico di raccordo, provvisto al suo interno di una coppia di elementi elastici di contatto di diametro rispettivamente 4,7 e 4 mm. In order to overcome this problem, the adoption of a single connection device has been proposed with the patent application GE 2006 A 000035, provided internally with a pair of elastic contact elements having a diameter of 4.7 and 4 mm respectively.

Tale dispositivo noto, anche se risolve in parte il problema del collegamento a spinotti di diametri differenti, presenta tuttavia degli svantaggi dovuti al fatto che non sempre à ̈ facile stabilire un buon contatto fra detti elementi elettrici, e che inoltre gli elementi metallici di contatto sono del tutto scoperti e sprovvisti di protezione isolante. This known device, even if it partially solves the problem of connecting pins of different diameters, nevertheless has some disadvantages due to the fact that it is not always easy to establish a good contact between said electrical elements, and that furthermore the metallic contact elements are completely uncovered and without insulating protection.

Costituisce pertanto lo scopo principale della presente invenzione realizzare un connettore per il collegamento elettrico fra una saldatrice e gli spinotti di raccordo dei manicotti di polietilene atti a venire saldati mediante elettrofusione su tubi o simili, atto ad ovviare agli inconvenienti dei connettori noti. Therefore, the main object of the present invention is to provide a connector for the electrical connection between a welding machine and the connecting pins of the polyethylene sleeves suitable for being welded by electrofusion on pipes or the like, able to obviate the drawbacks of known connectors.

Secondo la presente invenzione tale scopo viene conseguito montando su un elemento di base un elemento troncoconico in lamierino metallico formato da quattro spicchi articolati per la loro base maggiore a detto elemento di base, ed atti ad aprirsi a tulipano. Detti spicchi sono svasati in corrispondenza della loro estremità libera in modo da consentire l'inserimento di spinotti di diametro differente. Detto elemento troncoconico à ̈ rivestito da un cappuccio di un materiale elastomerico analogo alla gomma, avente una memona di forma atto a mantenere, e raffreddandosi a riportare detti spicchi in aderenza fra loro, e che costituisce ulteriormente un elemento di isolamento elettrico del lato esterno di dette lamine metalliche. According to the present invention, this object is achieved by mounting on a base element a truncated cone element in metal sheet formed by four segments articulated by their base greater than said base element, and adapted to open like a tulip. Said segments are flared at their free end so as to allow the insertion of pins of different diameter. Said frusto-conical element is covered by a cap of an elastomeric material similar to rubber, having a shape suitable for maintaining and cooling to bring said segments into adherence to each other, and which further constitutes an element of electrical insulation of the external side of called metal foils.

Ulteriori scopi e vantaggi del dispositivo secondo l'invenzione appariranno meglio dalla seguente descrizione di una sua forma esecutiva preferita, illustrata a titolo di esempio non limitativo nel disegno allegato, nel quale: Further objects and advantages of the device according to the invention will become clearer from the following description of a preferred embodiment thereof, illustrated by way of non-limiting example in the attached drawing, in which:

La figura 1 Ã ̈ una vista laterale in scala maggiore parzialmente sezionata di un connettore secondo la presente invenzione, e Figure 1 is a partially sectioned, larger scale side view of a connector according to the present invention, e

La figura 2 Ã ̈ una vista frontale del connettore di figura 1. Figure 2 is a front view of the connector of figure 1.

Con riferimento ai disegni, e con particolare riferimento alla figura 1 degli stessi, con 1 à ̈ indicato l'elemento di base del connettore secondo l'invenzione. L'elemento 1 reca da un lato un elemento di raccordo alla linea di alimentazione elettrica proveniente dalla saldatrice (non illustrata) e dall'altro lato presenta un mozzo filettato 3 dal quale SI estende un elemento troncoconico in lamierino metallico buon conduttore dell'elettricità formato da quattro spicchi 4 articolati per la loro base maggiore al mozzo di base 3, atti ad apnrsl a tulipano. Detti spicchi sono svasati In corrispondenza della loro estremità libera 104 in modo da consentire l'inserimento di spinotti di diametro differente, come ad esempio di diametro 4,Omm e 4,7mm. Detto elemento troncoconico à ̈ rivestito da un cappuccio 5 di un materiale elastomerico di elasticità analoga a quella della gomma, avente una resistenza alle alte temperature analoga a quella del teflon, dell'ordine da -20 a 200°C ed avente memona di forma per CUI à ̈ atto a mantenere, e raffreddandosi a riportare detti spicchi in aderenza fra loro, e che costituisce ulteriormente un elemento di isolamento elettrico e termico. Un materiale del tipo sopra esemplificato à ̈ per esempio quello prodotto dalla ditta Dow Corning Corporation USA con il nome proprietario di "Silastic"®. With reference to the drawings, and with particular reference to Figure 1 of the same, 1 indicates the base element of the connector according to the invention. The element 1 has on one side an element for connecting to the electrical power supply line coming from the welding machine (not shown) and on the other side it has a threaded hub 3 from which extends a frusto-conical element in metal sheet, a good conductor of electricity formed by four segments 4 articulated by their greater base to the base hub 3, suitable for tulip-shaped apnrsl. Said segments are flared at their free end 104 so as to allow the insertion of pins of different diameters, such as for example diameters 4, Omm and 4.7mm. Said frusto-conical element is covered by a cap 5 of an elastomeric material of elasticity similar to that of rubber, having a resistance to high temperatures similar to that of Teflon, of the order of -20 to 200 ° C and having a shape for CUI is designed to maintain and by cooling to bring said segments into adherence to each other, and which further constitutes an element of electrical and thermal insulation. A material of the type exemplified above is for example that produced by the company Dow Corning Corporation USA with the proprietary name of "Silastic" ®.

Con 6 à ̈ indicato lo spillo centrale di contatto, e con 7 à ̈ indicato un involucro esterno di protezione, di forma leggermente troncoconica In modo da imboccare più facilmente le boccole esterne di protezione degli spinotti di contatto elettrico (non illustrati), che viene assicurato al mozzo filettato 3 mediante avvitamento. 6 indicates the central contact pin, and 7 indicates an external protective casing, with a slightly truncated cone shape. secured to the threaded hub 3 by screwing.

Il funzionamento del dispositivo illustrato apparirà evidente. Nel corso della saldatura, a causa della forte intensità della corrente elettrica che passa fra le parti a contatto, si ha un riscaldamento notevole delle lamine di contatto 4, e quindi anche del cappuccio 5 di elastomero, che pertanto potrebbe tendere a esercitare una tensione minore sulle lamine 4. Questa tendenza viene tuttavia contrastata grazIe al fatto che detto elastomero à ̈ dotato di memoria di forma per cui raffreddandosi ritorna alla sua forma primitiva. The operation of the illustrated device will appear evident. During welding, due to the strong intensity of the electric current that passes between the parts in contact, there is a considerable heating of the contact plates 4, and therefore also of the elastomer cap 5, which therefore could tend to exert a lower voltage. on the laminae 4. This tendency is, however, counteracted thanks to the fact that said elastomer is endowed with a shape memory so that when it cools it returns to its original form.

Naturalmente la presente invenzione non à ̈ limitata alla forma esecutiva illustrata e descritta, ma comprende tutte quelle varianti e modifiche rientranti nell'ambito del concetto inventivo, sostanzialmente come a seguito rivendicato. Naturally, the present invention is not limited to the illustrated and described embodiment, but includes all those variations and modifications falling within the scope of the inventive concept, substantially as claimed hereinafter.

Così, per esempio, per quanto lo spillo 6 SIa stato illustrato come solidale con la base 3, esso può essere collegato a detta base tramite un sistema di molle che ne consentono la ritrazione elastica. Thus, for example, although the pin 6 has been illustrated as being integral with the base 3, it can be connected to said base by means of a system of springs which allow it to be retracted in an elastic manner.
