一种射频同轴电缆连接器用新型界面测试仪A new interface tester for radio frequency coaxial cable connector

技术领域technical field

The accuracy of dimension L directly affects the connection state of connectors and other devices, and the transmission of electrical performance, so it is very important. In the prior art, the above-mentioned interface size is usually measured by first measuring the dimension L1 and the dimension L2 with a common vernier caliper, and then subtracting the dimension L2 from the dimension L1 to obtain the dimension L. This test method requires two measurements, not only one more measurement work, but the work efficiency is halved, and the accumulation of the two measurement errors is easy to get a larger data error. Therefore, the RF coaxial cable connector interface for mobile communication Dimensional test methods and connector interface test instruments need to be optimized.
