Description

technical field [0001] The invention belongs to the technical field of thermal batteries, and relates to a leak-proof insulating snap ring with a mechanical buffer function. Background technique [0002] The thermal battery is a kind of thermally activated reserve battery that uses the heating system of the battery itself to heat and melt the non-conductive solid-state salt electrolyte into an ionic conductor and enter the working state. Thermal batteries have the characteristics of long storage time, short activation time, high specific energy, wide operating temperature range, maintenance-free, etc., and are widely used in missiles, torpedoes, bombs and other weapon systems. [0003] During the working process of the thermal battery, the internal temperature is as high as 400 ℃ ~ 500 ℃, and the trace electrode material will sublime into gas at high temperature, so that the insulation performance between the internal stack and the external metal shell will be greatly reduce...

AI Technical Summary

Problems solved by technology

The existence of induced voltage disturbs the collection and judgment of electrical data by the weapon system, and the electric leakage brings the risk of electric shock to the operator, and measures must be taken to eliminate

Since the metal shells of the thermal battery are all cylindrical, they are generally installed and fixed in the groove of the metal structure bracket. According to the current machining level, it is difficult to make the upper and lower sides of the metal shell of the thermal battery closely adhere to the groove of the metal structure bracket. In the mechanical environment, the cylindrical metal shell of the thermal battery is very easy to rotate and loosen in the groove of the structural support, which affects the stable output of thermal battery power.
