BS 1363-1条款12.2的理解
BS 1363-1条款12.2：从插合面算起不小于6.35mm的距离内，插头的外形不可超过图4所示尺寸。在此类尺寸中，插头的插合面上不可有轴向凸出。但当从插合面算起超过6.35mm的距离时，插头的外形可在接地插销的平面及软线入口的平面中（此两平面可便于插头从插座中拔出）超过图4a）中所示尺寸。请高人赐教，最好附图，谢谢！ Sorry that I don't really understand your question in Chinese.
Maybe this is your answer.... 谢谢！但有些地方还是解释不通，12.2是否原为如此：从插合面算起小于6.35 mm的距离内，插头的外形不可超过图4所示尺寸。在此类尺寸中，插头的插合面上不可有轴向凸出。但当从插合面算起超过6.35mm的距离时，插头的外形可在接地插销的平面及软线入口的平面中（此两平面可便于插头从插座中拔出）超过图4a）中所示尺寸
如何理解轴向？ Maybe you are misunderstanding this clause's meaning.
The outline must remain unchanged within 6.35mm. This outline must also be good fit to the Fig.5 guage. Otherwise your product failed to comply with the clause 12.2.
if the outline is greater than 6.35mm, then the shape of the plug is not specified.
I hope it is useful to you. 引用第3楼bs1363于2008-12-29 20:40发表的:

1. There is no any doubt on the Point that The outline must remain unchanged within 6.35mm,
2.if the outline is greater than 6.35mm, then the shape of the plug is not specified.
But How to comprehend the " in the plan of the earth pin and the plan of the cord entry"? what does it mean? Tks! 非常感谢！烦请各位以中文交流，本人的英文水平有限。 確實很好的討論，雖然英文看的比較霧！ To: leoluo
Maybe my explanation is not so clear.
The outline must remain unchanged within 6.35mm or the outline can be reduced within 6.35mm that it don't exceed the dimension shown the fig.4a.
The attachment I hope can make you understand easily.
This is my understanding. I am not sure whether or not it is 100% true. 引用第7楼bs1363于2008-12-30 22:07发表的:

Hi BSI1363:
I appreciate your help, I think your explanation is clear enough. Many Thanks. 标准里的意思是这样的：
在插头的接合面起6.35mm以内的尺寸内的外形尺寸不得超出FIGURE 4中规定的尺寸，至于大于6.35mm处的外形尺寸是没有要求的，可以大可以小。
在插头的接合面处（即插头与插座接触的平面），不得有凸出部分，如果有的话其凸出部分的高度不得大于0.5mm。
关于此问题，我问过相关人员，人家给我的答复是英式插座有的也像德法式一样，有插孔下沉的，但答复我的人说他也没有见过这种插座，我们所见的插座都是平面的接合面。
