Abstract

The invention provides a transmission line test device which is used for testing a transmission line and comprises a probe assembly and a floating supporting assembly. Wherein the floating support assembly is used for supporting the transmission line, and the probe assembly is used for being electrically connected with the transmission line; the floating supporting assembly comprises a supportingpart, a plurality of positioning parts arranged in the circumferential direction of the supporting part in a spaced mode, and elastic parts arranged in the circumferential direction of the positioningparts in a hooping mode. The invention provides a transmission line test device. The floating support assembly can support the to-be-tested transmission line to translate in two degrees of freedom, so that even if the probe assembly deviates from the initial position of the to-be-tested transmission line, the test work can be continued, the probe assembly can accurately and stably abut against the to-be-tested transmission line, and the false test rate is greatly reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of testing devices, in particular to a transmission line testing device. 【Background technique】 [0002] With the development of 5G and consumer electronics technology, research on multi-antenna technology has a long history. The space available for the layout of traditional RF coaxial transmission lines is getting smaller and smaller, so new transmission line structures (including FPC and connectors) have emerged as the times require. [0003] For the design of multi-antenna RF transmission lines, flexible material circuits (including connectors) are mainly used for RF transmission, and the superiority of its RF transmission performance plays a vital role. [0004] Testing the RF performance of transmission lines has become an important item in the mass production test of transmission lines. A stable, reliable and accurate test fixture can well measure the RF performance of the transmission line, and th...
