Abstract: An electrical insulation system for a linear element forming part of a fluid system subjected to risks of possible external electrical discharges, such as an aircraft fuel system, using an insulating insert (12) between two parts (14, 16) of said linear element, consisting of providing said parts (14, 16) with grooved edges and in forming the insulating insert (12) between them preferably by an injection technique, such that the insulating insert (12) provides an inner duct for the passage of fluid between said parts (14, 16) and covers said grooved edges, assuring the leak-tight joint of the insulating insert (12) with said parts (14, 16).

Abstract: The system is intended for fixing metal rivet nuts (1) to plastic material components (2), achieving the fixing by means of ultrasound riveting or any other mechanical method. Each plastic component (1), made through the relevant manufacturing process, preferably by injection moulding, has a plurality of protuberances (4) that are placed in the rivet nut holes (1). Riveting is subsequently carried out by ultrasound or other mechanical method on these nipples (4), fusing them and their corresponding union with the rivet nut (1) and in short, fixing the nut onto and integrating it into the plastic material component (2). The riveting system referred to for integrating rivet nuts into plastic components creates a union between the rivet nuts and other components that are part of a structure. These other components can be metallic or non-metallic.
