Description

A voice and telecontrol signal multifunctional test line

technical field

The embodiment of the utility model relates to the technical field of voice and telecontrol signal testing, in particular to a multifunctional test line for voice and telecontrol signals.

Background technique

With the continuous increase of communication sites, the business volume of voice and telecontrol signals has doubled, and the work of debugging and troubleshooting VDF distribution frames and audio cables has also increased. In order to meet the ever-improving communication management requirements, Especially for the control of the time node, in order to better provide efficient protection for the operation of the power grid, we are required to spend as little time as possible on audio cable work.

At present, there are many types of test lines used for VDF distribution frames and audio cables, and each test line can only perform a single function. Leaking a test line with a certain function will delay the work. During the operation process, the audio cable test for different tasks needs to be selected and replaced with test lines with different functions, which is time-consuming and inefficient, and seriously affects the quality of work. In addition, the traditional test line has a fixed length and is inconvenient to store. It is often entangled with other tools when placed in a tool bag, which is not easy to separate, and it will also cause poor contact of the test line end due to brute force pulling.
