Abstract (en)
[origin: WO2017140978A1] A method for producing an opto-pyrotechnic initiator (100) comprises the following steps: a) moulding of a body (110) comprising a cavity (111) in which a pyrotechnic load (105) is intended to be housed, the body further comprising an inner passage (112) extending between an inlet (113), opening on an outer face of said body, and the cavity (111) enclosing the pyrotechnic load (105), b) placing a first portion (121) of an optical fibre (120) in the inner passage (112) of the body (110), a second portion (122) of the optical fibre (120) extending beyond the inlet (113) of the body (110), a glass preform (140) being interposed between the optical fibre (120) and the inlet (113) of the body (110), c) thermally treating the glass preform (140) at a temperature greater than the melting point of said glass preform, in such a way as to mould a hermetic glass seal (150) between the optical fibre (120) and the inlet (113) of the body (110).
