打结 欧规是不接受的，国标一样一样的

建议用线扣

打結注意：1是不能太鬆，不然很容易散開失效；
- e, ?2 Z: v! L& G$ N2 }% q2是打結位置，預留的線長要足夠，不然結還未到位，接線已被拉掉了。

IEC/EN/GB 60598-1 clause 5.2.10 提到电源线需要使用cord anchorage ，摘录如下：
  C4 k& |) S2 k) n- G5.2.10 Luminaires provided with or designed for use with non-detachable flexible cables or cords shall have a cord anchorage such that the conductors are relieved from strain, including twisting, where they are connected to the terminals, and such that their covering is protected from abrasion. It shall be clear how the relief from strain and the prevention of twisting is intended to be effected. For luminaires supplied without a cable or cord, suitable test cables or cords of the largest and smallest sizes recommended by the luminaire manufacturer shall be used for the tests.
2 Z& G* o% O0 }+ b* I$ SIt shall not be possible to push the flexible cable or cord into the luminaire to such an extent that the cable or cord is subjected to undue mechanical or thermal stress. Methods such as tying the cable or cord into a knot or tying the ends with string shall not be used.
" W% S8 L# h) L% z9 h" y. eCord anchorage shall be of insulating material or be provided with a fixed insulating lining if an insulation fault on the cable or cord could make accessible metal parts live.

打结肯定是美洲灯具，应当不存在通不过的问题，关键是判定标准不对，不要看线皮的位移，把电源线内部接点断开，如果铜丝没有位移是算通过的．这种线皮的移动是可以接受的，不过结打好点是应该的．

版主的解说是很正确的。打结是需要有些技巧的，打好先用手拉拉，再测试。

最好采用软线固定架！·

除UL允许打结外，其它地区是不接受打结的。

不能采取别的措施吗？打结基本是通不过的！
