穿刺线夹接触不良痕迹特征研究

Research on the poor contact trace characteristic of insulation piercing connectors

在不同条件下,模拟制备JJC 1-35型穿刺线夹接触不良故障痕迹,对所得痕迹试样的宏观形貌、微观形貌、金相组织进行观察比较,并将其与穿刺线夹火烧痕迹特征进行对比,得出穿刺线夹接触不良痕迹特征规律,为调查此类火灾及物证鉴定工作提供依据。

In this paper,the type of JJC 1-35 insulation piercing connectors with poor contact traces has been simulated and fabricated under different conditions.The macro-morphology,micromorphology and metallographic structure of the samples have also been observed and compared.By comparing with the burning trace characteristics of the insulation piercing connectors,the poor contact trace characteristics of the insulation piercing connectors have been obtained.It has provided a basis for fire investigation and physical evidence identification.
