飞机用锌银蓄电池组副插孔的改进

Improvement of Sub-Socket of 15XYG45-(3) Alkaline Silver-Zinc Battery

15XYG45－（3）型锌银蓄电池组副插孔对接过程中，经常出现接触不良现象，影响用户的使用。经试验确定了铝合金防护套结构，从而增加了对接时的接触面积、减少了内阻，保障了飞行安全。

Bad contaet are usually found between sub-socket of silver-zine battery and plaug of the plane. We adopted aluminium alloy protector structure which increase contact surface area, leduce inner resistance and ensure the safety of flight.
