CA 2432444

In order to reduce acoustic noise, an electromagnetic relay (2) includes an insert or bump (20) located between the relay armature (4) and the relay core (8). The insert is flexible and can be mounted on the armature. The insert (20) reduces noise by decelerating the armature (4) at impact with the core (8). The armature (4) can be tilted relative to a surface of the core (8) so that the insert or bump (20) can be positioned away from the primary impact between the core and the armature.

Afin de diminuer le bruit acoustique, un relais électromagnétique (2) comprend une garniture ou un tampon (20) situés entre l'armature du relais (4) et le noyau du relais (8). La garniture est souple et peut être installée sur l'armature. Cette garniture (20) diminue le bruit en décélérant la course de l'armature (4) juste avant que celle-ci frappe le noyau (8). L'armature (4) peut être inclinée par rapport à une surface du noyau (8), de sorte que la garniture ou le tampon (20) puissent être éloignés du premier choc entre le noyau et l'armature.
