求翻译：We also tried to plug in a metal pin with 1.3mm outer diameter (nominal size) in plugs of the leads and it was nearly impossible in a lot of plugs . It seems that the fork plugs in a lot of leads maybe have not enough space in the overmoulding to open for 1.3mm diameter of the metal pin ?.是什么意思？
