多谢各位的回复, 那基本上输入线是要满足18AWG, 我现在LED 驱动的部分PWB上是没有变压器的,所以我可能描述的非隔离是错误, 所以应该输出线也要按照高压来评估,满足18AWG, 另外目前我们的灯具针对lamp base 的触点是直接焊上两条电线,标准要求:6.2.2 A soldered joint shall be mechanically secure before soldering 需要机械固定,
" I8 |8 | G/ b% k9 m/ o6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:
$ k7 d2 D. }$ w* h: m3 D1 Ea) At least one full wrap around a terminal,
5 h" v3 r6 W$ e5 x+ y2 h/ m( Gb) At least one right angle bend when passed through an eyelet or opening, except on printedwiring
8 T* w, O$ t3 b/ e1 fboards where components are properly inserted and soldered or mechanically secured
0 p4 J1 W! W# s. J7 fby design, or- u ?9 _1 A+ [3 L4 G
c) It is twisted with other conductors.所以我要确定是不是机械固定必须按照6.2.3的a,b,c, |
