5.物理特性

PHYSICAL CHARACTERISTIC

5-1 拉力測試

Tensile test

沿端子的軸向施加10N的拉力,持續1分鐘,管体不断开、破裂。

Keep pulling the cap of the fuse with 10N at axial direction for 1 min,and the pipe body is continuously opened and broken.

5-2管体强度测试

Strength of fuse tube

保险丝管体固定好后,在管体中央部位施加15N压力,管体不断开、破裂。

After the fuse pipe body is fixed, the 15N pressure is applied to the center position of the pipe body, and the pipe body is continuously opened and broken.
