连接器工作时,电流在接触点产生热量,导致温升,所以一般认为工作温度应该等于环境温度和接触点温升之和。在一些规范中,明确规定了额定工作电流下连接器的允许温升。

②防潮性的侵入会影响连接H和生锈金属部件的绝缘性能。恒定湿热试验条件为相对湿度90%~95%,温度+40±20℃,试验时间按产品规定至少96小时。湿热交替试验更厉害。

③耐盐雾连接器在含有湿气和盐的环境中工作时,金属结构件和接触件的表面处理层可能发生电化学腐蚀,pin针标准可能影响连接器的物理和电气性能。为了评估电连接器承受这种环境的能力,规定了盐雾试验。连接器悬挂在温控试验箱中,形成盐雾环境,pin针其暴露时间至少为产品规范规定的48小时。

(4)振动和冲击抗振动和冲击是电连接器的重要性能,是检验电连接器机械结构牢固性和电接触可靠性的重要指标。相关测试方法有明确规定。冲击试验中应规定峰值加速度和电气连续性的中断时间。

⑤其他环境性能根据使用要求,电连接器的其他环境性能包括密封性能和低气压。
