ABSTRACT:
The invention relates to an integrated device (1) for the protection against electrical discharges of conductive fixing elements (2) between one another or of a fixing element and another conductive element of aircraft, comprising a cap (3) and an o-ring gasket (4) made of non-conductive insulating material, the mentioned integrated device (1) comprising a modified fixing element (2) working together with the cap (3) and the o-ring gasket (4), the fixing element (2) surrounding the cap (3) and the o-ring gasket (4) in a non-conductive manner, thus preventing the possibility of electrical discharges such that in the device (1) the number of necessary components is minimized, the impact in weight for the aircraft being minimum, the modified fixing element (2) further comprising a thread (5) on the outer face of the area that has to be protected.
