Description

Technical Field

[0001] The utility model belongs to the technical field of radio frequency cable testing, and in particular relates to radio frequency cable intermodulation testing equipment. Background Art

[0002] RF cable is a cable that transmits electromagnetic energy in the radio frequency range. RF cable is an indispensable component in various radio communication systems and electronic equipment. It is widely used in wireless communication and broadcasting, television, radar, navigation, computers and instruments. RF cable needs to undergo a series of tests before actual use. During the RF coaxial cable testing process, RF coaxial cable testing equipment is required. In actual use, the existing RF coaxial cable testing equipment is manually screwed together by two people using a wrench to manually connect the two ends of the intermodulation RF coaxial cable assembly to be tested and the two RF coaxial adapters. The connection efficiency is low, and the wrench surface of the product may be scratched, affecting the service life of the RF coaxial cable.

[0003] The patent with application number 202321102179.2 discloses a radio frequency cable intermodulation test device, including a box body, which is provided with two detection areas. The detection areas include a first clamping member and a second clamping member, both of which are movably installed inside the box body through a connecting component, a driving device, which is fixedly installed inside the box body and fixedly connected to the first clamping member, for driving the first clamping member and the second clamping member to move, and a test line, which is fixedly installed on the first clamping member, and a second clamping groove is provided on the second clamping member, and the second clamping groove is used to clamp the cable to be tested. The second clamping groove is adapted to the position of the test line, and the driving device is started, and the first clamping member starts to move toward the second clamping member until the second clamping member fits the inner wall of the box body.

[0004] The above technical solution clamps and fixes the RF cable to be tested through a driving device, and avoids scratches on the RF cable body during the detection process by destroying the test line installed on the test equipment. Since the test line and the test equipment maintain a fixed connection, the test line needs to be stripped and connected to the test equipment during each test, which causes the test line to become shorter and need to be replaced after multiple uses. The fixedly connected test line is not convenient to replace. Utility Model Content
