The invention relates to a non-pyrotechnic high-shear-bearing low-impact connecting and separating mechanism. The non-pyrotechnic high-shear-bearing low-impact connecting and separating mechanism is characterized in that a breaking bolt threaded section is fixedly connected with a shear-resistant nut; the heater and the SMA pipe are sequentially arranged on a polished rod of the breaking bolt in a sleeving mode from outside to inside, and the gasket is used for fixing the axial position of the SMA pipe. The shell is arranged between the anti-shearing nut and the gasket, an annular groove serving as a weakening groove is machined between the threaded section of the breaking bolt and the polished rod, and the position of the weakening groove in the breaking bolt corresponds to the axial position of the shell; the shell is fixedly connected with the periphery of the external fixing seat; the shear nut is sleeved with a clamping piece, and the fixing nut is used for fixing the axial position of the clamping piece so that the end face of the clamping piece can be attached to the end face of the fixing base. The unlocking device is small in size, light in weight and high in bearing capacity, the main executing mechanism can be repeatedly used, and the application cost of the unlocking device is greatly reduced.

    本发明一种非火工型高承剪低冲击连接分离机构,包括:破断螺栓螺纹段和抗剪螺母固定连接;加热器和SMA管由外至内依次套装在破断螺栓的光杆上,垫片用于对SMA管的轴向位置进行固定;外壳设置在抗剪螺母与垫片之间,破断螺栓的螺纹段和光杆之间加工有环槽作为削弱槽,破断螺栓上削弱槽的位置与外壳的轴向位置对应;外壳与外部固定座周圈固定连接;抗剪螺母外部套装有夹持件,固定螺母用于固定夹持件的轴向位置,使夹持件的端面贴靠在固定座的端面上。本发明是一种体积小、重量轻、承载力强的解锁装置,并且主要执行机构能够重复使用,大大降低了解锁装置的应用成本。
