Destruction-free press connection on pyromechanical securing elements

Abstract

The invention relates to a pyromechanical securing element for the mechanical connection of two components. The securing element comprises a covering (1) and a pyrotechnical propellant charge (6) is arranged in the head part thereof (5), said propellant charge being adjacent to an adapter (2), and securing means or a stop for the first component are arranged on the rear part of the covering (1) and a second component can be pushed onto the covering between the first component and the head part (5). The covering (1) on the head part (5) comprises expected fracture indents extending in the longitudinal direction which tear open the covering (1) in the head area when the propellant charge (6) is ignited and the first component is rigidly connected to the second component in order to allow the adapter (2) to bend. The aim of the invention is to securely anchor the covering (1) to the adapter (2) without using extreme force. Said invention is characterised in that the groove (3) is arranged in the adapter (2) in such a manner that it at least sectionally surrounds the outer periphery thereof, and that a radially protruding collar (4) is arranged on the outer surface of the cover (1) before the cover (1) is anchored to the adapter, and the groove (3) disposed in the adapter (2) is flush with the collar (4) of the cover (1) and at least one part of the collar (4) is pressed into the groove in order to anchor the cover (1) with the adapter (2).
