The invention provides a connecting and separating device based on memory alloy wire driving, which comprises a driving end and a driven end, wherein the driving end comprises a shell, an outer sleeve, a fixed sheet, a compression spring, a rotary sleeve, a base, a memory alloy wire, a guide wheel, a lock pin, a limiting sleeve I and a limiting sleeve II, and the driven end comprises a screw rod,a loading nut, a separating piece and an adapter piece; the upper end of the screw rod is a threaded section matched with the loading nut, and the lower end of the screw rod is provided with multiplelayers of inclined bulges; the multiple layers of inclined bulges extend into the upper part of an accommodating space formed by the limiting sleeve I and the limiting sleeve II; when the memory alloywire is powered on, the memory alloy wire is shortened, the base and the lock pin move upwards, the lock pin relieves limiting of the lower ends of the limiting sleeve I and the limiting sleeve II, the two limiting sleeves rotate simultaneously, the lower portions of the limiting sleeve I and the limiting sleeve II are folded, the upper portions of the limiting sleeve I and the limiting sleeve IIare opened and separated from the screw rod, and the driving end and the driven end are separated. The device realizes rapid separation, and has the advantages of no impact, energy conservation, environmental protection, small size, high reliability and reusability.

    本发明提供了一种基于记忆合金丝驱动的连接分离装置,包括主动端和被动端,主动端包括壳体、外套、固定片、压缩弹簧、旋套、底座、记忆合金丝、导轮、锁销、限位套Ⅰ和限位套Ⅱ,被动端包括螺杆、加载螺母、分离件和转接件;螺杆上端为与加载螺母配合的螺纹段,下端设有多层倾斜凸起;多层倾斜凸起伸入限位套Ⅰ和限位套Ⅱ形成的容纳空间的上部;记忆合金丝通电时缩短,底座和锁销上移,锁销解除对限位套Ⅰ和限位套Ⅱ下端的限位,两个限位套同时回转,限位套Ⅰ和限位套Ⅱ的下部收拢,限位套Ⅰ和限位套Ⅱ的上部张开与螺杆分离,实现主动端和被动端分离。本发明实现快速分离,具有无冲击、节能环保、体积小、可靠性高、可重复多次使用的优点。
