STRUCTURAL ELEMENT CONNECTOR/DISCONNECTOR Russian patent published in 2011 - IPC B64G1/64 F42B15/36 

FIELD: transport.

SUBSTANCE: invention relates to machine building and may be used mainly in space engineering for spaceship stages coupling. Proposed connector/disconnector consists of two parts with elements for fastening to structure elements, explosive bolt fitted in body first section bore with its heat and tail jointed with first and second sections of the body. It features hollow head. Device comprises also piston with rod fitted in explosive bolt cavity, damping element and working charge with its actuators arranged inside body second section, on piston side. Device is provided with damping insert made up of hollow truncated cone arranged in tape groove made in body first section bore to embrace taper transition between bolt rod and head. Explosive bolt cavity bore is taper groove. Angular groove is made on piston lateral surface on rod side, while piston is provided with taper transition from annular groove to rod. Damping element is made up of hollow cylinder embracing piston annular groove and, partially, piston taper transition. Damping insert and damping element are made from plastic irreversibly deformable material.

EFFECT: reduced shock pulses acting on separated elements, higher tightness.
