通信电缆、连接器及组件屏蔽效率对比验证

Contrast Test Verification of Shielding Efficiency of Communication Cables, Connectors and Their Assemblies

通过用混响室、三同轴、吸收钳等不同的测试设备对三十三个电缆组件样品的屏蔽效率进行行业对比试验,分析得出各测试设备的有效范围、不同测试设备间的关系以及屏蔽效率与频率、长度、测试位置的关系,给出了不同测试设备的改进建议及我国应优先制定的屏蔽效率标准建议。

Based on the contrast test of shielding efficiency of communication cables, connectors and their assemblies in reverberation chamber, tri-axial, absorbing clamp test equipment by using 33 cable assembly samples, valid range of each test equipment and the relationship between the different kind of test equipment and also the relationship between shielding efficiency with the frequency, length of samlpe, test position are analyzed. It has given the suggestion that each test equipment needs to be improved and the priority to develop standards of shielding efficiency.
