Abstract:
1. A connecting device comprising: a first plate shaped element comprising a first edge and a first thickness; a second plate shaped element comprising a second edge and a second thickness, which is less than the first thickness; a shaped groove having a cavity formed at least in part by the first edge, the second edge, a first flange, and a second flange; said first flange comprising an interior surface, an exterior surface, and a thickness therebetween; a pyrotechnic fuse placed in the cavity at a bottom of the shaped groove; a bore formed through the first flange, the second flange, and through the first plate shaped element; said bores being aligned and defining a first common bore having a mechanical connector disposed therethrough and secured in place; and wherein the first flange comprises a first rupture area defined by a single notch on the exterior surface and through at least part of the thickness so that a remaining thickness remains on the first flange, and the second flange comprises a second rupture area defined by a shoulder at a juncture of a first planar surface and a second planar surface, the distance from the second edge to the first planar surface defining a width, which is greater than the remaining thickness; and wherein the second rupture area is located near an end of the pyrotechnic fuse in the shaped groove and the first rupture area is located further away from the end of the pyrotechnic fuse in the shaped groove than the second rupture area.
