[0002] The current and voltage data of the distribution cabinet are connected through lines. The display device for collecting data is connected to the circuit during data collection. The voltage and current of the circuit are transmitted to the sensor to complete the data collection. The sensor then transmits the data to the display screen for display, so as to understand the current and voltage of the distribution cabinet in real time.

[0003] However, the outside of the wire is insulating rubber and the inside is copper wire. The copper wire has the characteristic of easy deformation and bending.

After breaking, it is easy to produce metal sliding friction under metal extrusion and loosen, which can easily affect the metal contact when the wire is fixed. Utility Model Content
