Plug connection is separated in the process of exploitation PARTS PRODUCTS AND FIXING ASSEMBLY releasable connection

摘要

FIELD: machine building.;SUBSTANCE: detachable connection of product parts separated during the operation is characterised by the fact that sealed working cavity of pyrotechnic opening drive of fastening assembly is formed with cylindrical surfaces of stock and channel of case, as well as with flange of cylindrical stock and annular end surface formed with stages of stepped cylindrical channel of case. Threaded socket for pyrotechnic pressure source is made in cylindrical stock on the side of device housing and coaxially to it. Power receptacle linked with plug of pyrotechnic pressure source is rigidly fixed on the device housing. In fastening assembly of detachable connections separated during operation of product parts, the shutoff elements are made in the form of parts of flat ring, the planes of which are adjacent as to outer and inner diameters with surfaces of circular toroid, the circle diameter of which does not exceed the ring thickness; at that, the above parts of flat ring are restricted on sides with planes that are parallel and symmetrically located relative to longitudinal axis of ring, and radial holes of case are made in the form of rectangular openings.;EFFECT: improving operating characteristics of the device; enlarging its operating capabilities.;7 cl, 6 dwg
