摘要
针对动车用压接端子过载承受能力的研究,设计了13种不同线缆线径和8种压线钳的合理压接匹配分组,压接并对所得压接端子试样均进行短时耐受流试验,测量了各个试样在试验前后的压接电阻值,计算出电阻值变化率。采用了Origin7.5对短时耐受流试验进行数据处理,并对比分析,研究了线缆线径与压线钳的匹配关系和压接工艺这两个方面对压接端子性能的影响。研究结果表明:线缆线径与压线钳的合理匹配关系会导致压接端子过载承受能力的不同,为了保证高品质电气性能的压接端子,应针对不同线径的线缆采用不同型号的压线钳进行压接,并严格把控压接质量。
Aiming at researching EMU crimping terminals overload capacity, designed the reasonable crimp matching group with thirteen different cable diameters and eight crimping pliers, resulting samples were short-term tolerance flow tested, the crimp resistance value was measured during test, resistance change rate was calculated, it was analyzed by software Origin7.5, crimping process and matching relationship between cable diameter and crimping pliers were studied. The results show that matching relationship between cable diameter and crimping pliers leads to different overload capacity of crimp terminals, and crimping process also has influence on its performance. in order to obtain high quality thermal performance crimp terminals, different types of crimping pliers should be used for different diameter clamps, and crimping quality should be strictly controlled to improve crimping process.
