3.3.2 *******For socket-outlets intended to accommodate plugs with flat pins, contact shall be made with both sides of each pin, except that it shall be permissible to use spring-assisted single-sided contacts.

我的理解,打算插合扁插销插头的插座,应与插销双边接触,但允许弹簧辅助的单边插套。后面These contacts shall not rely exclusively on the resilience of the contact material9 f( S+ e9 T' f) S

另外,象3.1.1和3.3.1对端子和插套材料只给出了一句笼统的概括,实际检测和生产中,一般使用哪些材料算合格?是参考插头部分对端子和插销材料的规定吗? |
