Description

Technical Field

[0001] The utility model relates to the technical field of cable test auxiliary devices, in particular to an auxiliary tool for shielded cable testing. Background Art

[0002] The network analyzer generates a set of swept-frequency signals and couples them to a straight conductor that is parallel to and close to the shielded cable under test. The swept-frequency signals are emitted from the straight conductor. The shielding layer of the cable under test "tries" to completely absorb the swept-frequency signals and conduct them completely into the earth. The "residual" part of the swept-frequency signals that is not shielded passes through the shielding layer and reaches the conductive layer of the cable under test. The conductive layer then "feeds back" the signal to the network analyzer. The network analyzer performs spectrum analysis on the signal, and the spectrum value reflects the shielding effectiveness of the shielding layer.

The mounting bracket is equipped with a connecting device, and the two ends of the cable under test are connected to the network analyzer through the connecting device." When installing the mounting bracket, the patent uses bolts and screw holes to match the position of the mounting bracket, which is inconvenient to position and troublesome to operate. In addition, the device does not consider whether there will be looseness after connection if only the mounting bracket is used to connect to the cable. Utility Model Content
