protection of a elektropyrotechnischen device against electrostatic discharges.

摘要

The protection is ensured by a discharger (30) providing at least one breakdown zone between the frame and each of the junction pins (16, 18) allowing electrical current to be supplied to a resistance element (10) placed in contact with a pyrotechnic composition and intended to make it possible to ignite the latter by the Joule effect. The discharger consists of an insulating layer (44, 46) formed by the thin-layer deposition of an insulating material on a conductive substrate (32) connected to the frame and of conductive layers (48, 50) connected respectively to the junction pins and formed in different zones on the insulating layer in order to provide breakdown zones (40, 42) between the substrate and each conductive layer.
