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. These contacts shall not rely exclusively on the resilience of the contact material

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? |
