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,# f k0 @5 d* S& D; {- x
6.2.3 A wire is considered to be mechanically secure when one or more of the following is provided:
6 N; q s; _& [1 a8 Wa) At least one full wrap around a terminal,) W6 b; Q8 u/ n4 y, ]( ^
b) At least one right angle bend when passed through an eyelet or opening, except on printedwiring/ g6 Q' Z- d7 g. r0 l8 z
boards where components are properly inserted and soldered or mechanically secured
8 g9 V8 q# w. X/ k& q! Sby design, or) _+ U0 @8 q) s' @! B1 T
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, |
