Abstract

L'invention concerne un détonateur électrique de sécurité. Il comporte, en plus des dispositifs courants de protection, à savoir une résistance et une douille de ferrite, un manchon isolant qui sépare le conducteur tubulaire extérieur du carter et qui permet que des charges électrostatiques accumulées sur le conducteur tubulaire s'écoulent par le carter en amorçant un arc à travers ce manchon isolant. L'invention s'applique notamment à des détonateurs de gonfleur de sac pneumatique de protection dans des véhicules automobiles.
