AN ELECTRO-WELDING ELEMENT OF CONDUCTIVE PLASTIC AND AN ELECTRO-WELDING COUPLING INCLUDING SAID ELEMENT FOR INTERCONNECTING PIECES MADE OF PLASTIC

摘要

The invention relates to an electro-welding element for interconnecting two pieces made of plastic, the electro-welding element being made of conductive plastic, either an intrinsically conductive plastic or an extrinsically conductive plastic. In a preferred embodiment, the electro-welding element includes an electro-welding portion constituted by two cylindrical sleeves and a thermoregulation portion constituted by a central portion interconnecting the two sleeves. An electro-welding coupling for interconnecting two tubes made of plastic may be formed by overmolding a plastic sleeve onto the electro-welding element, the sleeve being provided with power supply terminals.
