Abstract

L'invention décrit un boîtier obturateur (111) à collerette, partie intermédiaire et extrémité arrière à monter dans l'ouverture (28) d'une paroi mince telle qu'une porte d'armoire métallique (26) ou un couvercle de boîtier métallique, où le boîtier obturateur (111) est maintenu par un ou des ressorts (46, 146) s'appuyant contre les bords de l'ouverture ou la surface arrière (42) de la paroi mince (26) après introduction dans l'ouverture (28) de l'extrémité arrière (68) et de la partie intermédiaire jusqu'à la collerette (30) et où le ou les ressort(s) s'appuyant contre les bords de l'ouverture ou la surface arrière de la paroi mince sort(ent) de la surface extérieure de la partie intermédiaire du boîtier obturateur près de son extrémité ou bien de l'extrémité du boîtier obturateur et est (sont) relié(s) rigidement au boîtier (111). Selon l'invention, l'ouverture (28) dans la paroi mince (26) est ronde ou uniquement pourvue de parties rétrécies découpées en forme de corde décalées les unes par rapport aux autres et le profil extérieur du boîtier (111) est rond ou présente des méplats (38) correspondant aux parties rétrécies découpées en forme de corde. La surface supérieure du boîtier (10) vient en retrait (le cas échéant, dans les zones situées entre les méplats, si ceux-ci existent) et forme ainsi, au niveau de ses faces extérieures, des rainures orientées axialement, desquelles sort(ent) le (ou les) ressort(s). Si les méplats (38) existent, ces ressorts sont disposés dans leur zone et le boîtier (111) forme un espace d'emboîtement (72), dans la zone de deux méplats (38) situés l'un en face de l'autre, pour chaque ressort (46) sortant de l'extrémité du boîtier (78).
