The invention relates to a vibration damper (5) that can be provided between an electronic housing (1) and the fixed structure of an aircraft nacelle (3). It comprises a block of an elastic material (10), a screw (7) for securing the block (10) to said fixed structure (3), and means (11, 29a, 29b) for securing said housing (1) onto said block (10). It is characterised in that it comprises means (13, 15) for limiting the travel of said attachment means (11, 29a, 29b) relative to said securing screw (7) in at least two directions of the space, wherein the limitation means (13, 15) are sized so as to prevent any strain on the screw (7) that could lead to the fatigue and/or breakage thereof.
Cet amortisseur de vibrations (5) est apte à être interposé entre un boîtier électronique (1 ) et une structure fixe de nacelle d'aéronef (3). Il comprend un bloc en matériau élastique (10), une vis (7) de fixation de ce bloc (10) sur ladite structure fixe (3), et des moyens (11, 29a, 29b) de fixation dudit boîtier (1) sur ledit bloc (10). Il est remarquable en ce qu'il comprend des moyens (13, 15) pour limiter la course desdits moyens de fixation (11, 29a, 29b) par rapport à ladite vis de fixation (7) dans au moins deux directions de l'espace, ces moyens de limitation (13, 15) étant dimensionnés pour éviter une sollicitation de ladite vis (7) pouvant conduire à sa fatigue et/ou à sa rupture.
