插针插孔

如果插孔内导体孔径小于规定尺寸The inner conductor Jack size or pin dimensions is not correct

那么当插针内导体的插针进入插孔时就会使得插孔过度扩张，形变量超出其弹性形变范围，产生塑性变形，导致插孔内导体损坏；相反，如果插针直径过小，当插针和插孔配合时，插针与插孔壁之间的间隙过大，两内导体不能紧密接触，接触电阻变大，连接器的电气性能指标会很差。

If the jack conductor aperture is less than the required size, then when the pins of the inner conductor into the jack will make Jack over expansion, deformation beyond the elastic deformation, plastic deformation, resulting in damage to conductor holes; on the contrary, if the pin diameter is too small, when the pin and the jack with the gap between the pin and the jack. The wall is too large, the two inner conductor cannot close contact, contact resistance becomes large, the electrical connector performance will be very poor.
