Abstract

Anordningen er tenkt for å sette sammen midlertidig to mekaniske deler (1, 2). Den omfatter en stang (3) som har en slik størrelse at den går gjennom delene (1, 2) langs aksen, anordninger (4, 5) som samvirker med stangen (3) for å spenne aksielt delene (1, 2) mellom endene av stangen (3), en skjør ringformet halsdel (8) dannet på stangen (3) og pyrotekniske anordninger (12, 13, 14, 15) for selektivt å brekke stangen (3) på nivå med halsdelen (8) og å frigjøre på denne måten delene (1, 2) fra deres sammensetning. Ifølge oppfinnelsen vil de pyrotekniske anordningene (12, 13, 14, 15) omfatte en tett kapsel (1 2) som er innført i et aksielt hulrom (7) i stangen (3) og som omfatter en eksplosiv ladning (13) anordnet i nærheten av halsdelen (8). Kapselen (12) er laget av et materiale som er egnet for å følge deformasjoner i det plastiske domenet uten effekt for tettheten under ladningens eksplosjon og for å overføre isoleres til stangen (3) spenninger som er egnet til å sikre bruddet av de nne på nivå med halsdelen (8). Dette bruddet vil ikke føre til utsendelse av forurensende rester. Anvendelse ved romteknologi.The device is intended to temporarily assemble two mechanical parts (1, 2). It comprises a rod (3) having a size such that it passes through the portions (1, 2) along the axis, means (4, 5) cooperating with the rod (3) to axially tension the portions (1, 2) between the ends. of the bar (3), a fragile annular neck portion (8) formed on the bar (3) and pyrotechnic devices (12, 13, 14, 15) for selectively breaking the bar (3) at the level of the neck portion (8) and releasing on this way the parts (1, 2) from their composition. According to the invention, the pyrotechnic devices (12, 13, 14, 15) comprise a sealed capsule (1 2) inserted in an axial cavity (7) in the rod (3) and comprising an explosive charge (13) disposed in the vicinity. of the neck portion (8). The capsule (12) is made of a material suitable for following deformations in the plastic domain with no effect on the density during the explosion of the charge and for transferring insulated to the rod (3) voltages suitable to ensure the breakage of the nne at level with the neck portion (8). This breach will not result in the release of pollutant residues. Use in space technology.
