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