Problems solved by technology

This method of testing is costly and inefficient
Because two matching connectors must be installed for each cable to be tested, otherwise the test cannot be performed
Since the connectors cannot be disassembled and reused after mating with the cables, a large number of connectors are lost, resulting in very high testing costs; in addition, professional operations are required to install the connectors, which leads to very low test efficiency

Embodiment Construction

[0016] Specific embodiments of the present invention will be further described in detail below.

[0017] Such as figure 1 with figure 2 As shown, the test fixture of the present invention includes an instrument connection end 10 and a cable connection end 12 connected to the tested cable (not shown), and the cable connection end 12 is a standard SMA male head for testing with a vector network analyzer, etc. connected to an instrument (not shown). The cable connection end 12 and the instrument connection end 10 are connected by threads, and a coaxial and communicating inner hole 14 is arranged between the cable connection end 12 and the instrument connection end 10 . The cable connection end 12 is provided with a cup-shaped cable socket 16 . A cylindrical sleeve 18 with both ends open can be alternatively arranged in the cable socket 16 . Sleeve 18 is externally connected with a cylindrical pressure cylinder 20 with both ends open. The outer wall of pressure cylinder 20 is...

Abstract

The invention discloses a test fixture. The test fixture disclosed by the invention is characterized in that one end of the test fixture is an instrument connecting end connected with a detecting instrument and the other end of the test fixture is a cable connecting end connected with a detected cable; the cable connecting end is connected with the instrument connecting end through screw threads;and coaxial and interlinked inner holes are formed between the cable connecting end and the instrument connecting end. The test fixture is characterized in that a cupped cable socket is arranged at the cable connecting end; and cylindrical sleeves with two open ends can be exchangeably arranged in the cable socket. The test fixture disclosed by the invention is provided with exchangeable sleeves;and the sleeves with different inner diameters are exchanged along with test cables with different diameters and can be suitable for various test cables, thereby reducing the loss of a connector. Furthermore, the test fixture disclosed by the invention has the advantages of convenience in connection, high efficiency and the like.

Description

technical field [0001] The invention relates to a cable clamp, in particular to a test clamp for cable testing. Background technique [0002] In the field of radio frequency microwave communication, high-end radio frequency cables are required for signal transmission in various occasions. All cables used must be tested for radio frequency electrical properties after production to ensure that the electrical properties of the cables meet the specification requirements. At present, the testing of cables in the industry is to connect matching coaxial connectors at both ends of the cable, and then connect it to a vector network analyzer for electrical performance testing. This method of testing is costly and inefficient. Because two matching connectors must be installed for each cable to be tested, otherwise the test cannot be carried out. Since connectors cannot be disassembled and reused after mating with cables, a large number of connectors are lost, resulting in very high ...
