Abstract: An explosive attachment device for mechanical connection of components, internally provided with an explosive charge, the detonation shock effect of which is strong enough for rupturing a connection forming part of the attachment device for a rapid disconnection, whereby the attachment device incorporates an attachment screw (2) and an explosive attachment element (4-14) which comprises a cylinder (4), a cover (5), and a piston (6) mounted in the cylinder (4), a space between the piston (6) and the bottom of the cylinder (4) is provided with a circular row of small holes (14), the piston (6) is provided with a rod (7) that the attachment screw (2) is mounted to, in the space between the piston and the cover (5) is arranged the explosive charge (9) with a firing device (10,11,12,13) having a delay mechanism, whereby the blasting pressure is converted to a pulling stress, which acts upon the attachment screw (2) to be pulled off without the other parts splintering.

Abstract: Explosive attachment device for mechanical connection of components, internally provided with an explosive charge, the detonation shock effect of which is strong enough for rupturing a connection forming part of the attachment device, for a rapid disconnection, whereby the attachment device incorporates an attachment screw (2), which extends through the inteconnected components (1) and an explosive attachment element (4-14) in which the attachment screw (2) is fixedly mounted, thus that the interconnected components (1) are clamped between the head of the said attachment screw (2) and the explosive attachment element (4-14), which explosive element (4-14) comprises a cylinder (4), which is closed by means of a cover (5).
