For the laboratory measurement of the transfer impedance and shielding attenuation effect of the coaxial cable, a network analyzer is used to connect the two ends of the cable to be tested for measurement, and in order to reduce the interference of the external environment on the coaxial cable, the test The result is accurate and shows the data of the coaxial cable itself purely. The coaxial cable to be tested is placed in the coupling tube 1 to measure the isolated external environment (such as figure 1 As shown), the two ends of the coupling tube 1 have terminals connected to the two ends of the coaxial cable, and the rear terminal 11 is the data input terminal. It is necessary to connect the load at the rear terminal 11 first, and then connect the Cable joints, the structure of the exis

The invention discloses a load-carrying connector for coaxial line shielding efficiency testing. The load-carrying connector includes a cylindrical outer conductor, a center pin is arranged at the position of the central axis inside the outer conductor, the upper part of the outer conductor is a cable plugging part and the lower part of the outer conductor is a metal tail pipe, the bottom end of the center pin is connected with a load and is arranged in the metal tail pipe, the inside of the metal tail pipe is sealed by metal, a shielding casing with threads on the outer surface sleeves the metal tail pipe, and one end of the load is connected with the center pin and the other end of the load is connected with the outer conductor. The load-carrying connector for coaxial line shielding efficiency testing has one end capable of being plugged with a cable plug and the other end capable of being plugged or threadedly connected a rear port, the testing is convenient, no extra load needs to be connected, and the shielding efficiency effect is good.
Description
technical field [0001] The invention relates to the field of cable testing equipment, in particular to a special tape-loaded connector used in a coupling tube for testing the shielding efficiency of a coaxial line. Background technique [0002] The coaxial line is a common signal transmission line. The copper core in the center transmits high level and is covered by insulating material; Shielding effect. For the laboratory measurement of the transfer impedance and shielding attenuation effect of the coaxial cable, a network analyzer is used to connect the two ends of the cable to be tested for measurement, and in order to reduce the interference of the external environment on the coaxial cable, the test The result is accurate and shows the data of the coaxial cable itself purely. The coaxial cable to be tested is placed in the coupling tube 1 to measure the isolated external environment (such as figure 1 As shown), the two ends of the coupling tube 1 have terminals connect...
