摘　　要：通过对硬同轴线接插头断裂样品分析,分别检验了样品的化学成分、硬度和金相组织,采用扫描电子显微镜观察了断口的微观形貌。结果表明,使用过程中断裂的样品是由于工作环境温度高导致第二相和晶体长大,材料强度下降而产生的断裂;产品装机试验时断裂的样品是由于固溶处理过热而产生的脆性断裂。通过分析,提出了接插头质量控制和使用环境控制的措施。The unique structure and process characteristics of pin and socket connectors in rigid coaxial line were introduced. Under large power transmission condition, crack of pin and socket connectors in rigid coaxial line were summarized and analyzed. Innovative approaches were taken to improve the heat treatment of rigid coaxial line. And several suggestions on improvements of reliability of pin and socket connectors were also proposed.
