What is the weak box for?

Weak electrical boxes can be used to place communication, intelligent control and other equipment, and are generally used to sort out weak electrical lines such as network cables and telephone lines. The voltage of weak current is lower than that of strong current, generally below 36V safe voltage, so for 36V, it is a sign to distinguish strong current from weak current.

Second, the weak box installation matters needing attention

1, weak box installation position is generally in the indoor incoming and outgoing positions, such as hanging up position or closet.

2. After the installation location is selected, the box body can be buried in the wallboard to expose the wall 1cm, and the outlet holes on both sides should be buried. Only after all wiring has been tested can it be sealed with lime.

3, 65438 +0.5 meters from the ground, dry and ventilated parts, as far as possible away from the high voltage distribution area.

4. When installing the coaxial cable connector of CATV, pay attention to peel off the coaxial outer sheath, cut off the hidden net, and don't use the shielding net to contact the copper core for short circuit. For coaxial cable, insert it into the end and fasten it with the fastening ring.

5. Audio and video cables must be welded with electric soldering iron. At present, all kinds of audio-visual accessories supplied in the market must use welding installation technology. Although cumbersome, it is still reliable for the signal.
