8字尾正常操作在VDE测试失败，求改善

不合格说明如下，请各位吹吹如何改善,内架和端子都为GEM认证专用的：
20Normal operation
After the test (2000 strokes with rated current and 6000 strokes without current flowing) the electric
strength test as specified in clause 15.3, reduced to 1500 V has not been fulfilled.
Flashovers between the contact tubes and a metal foil at the engagement face of the connector have
been occurred at 800 V, 1200 V and 1500 V.
Flashover between the contact tubes occurred at 1450 V.
在1450V时连接铜管产生闪烁。

铜管材质有问题，弹性不好。

有没有高手还有不同看法？

这么多天了没有高手出来呀，自己发表，呵呵
我请教了高手，可能是两个原因，一是材料，二是模具（制作工艺）

成型压力和内架也有关系，关键要看内架是不是已经变形。

铜套弹性太小，摩擦掉太多铜削，电测闪络。
