With the increase of weak current demand, weak current lines will become more and more complicated, so it is necessary to manage weak current centrally.
The owner can install a weak box similar to a strong box to centrally manage and maintain the lines of network information home appliances such as telephone, fax, computer, TV and security monitoring equipment in the room.
Installation of weak electrical box The general size of weak electrical box in home decoration is 320X260mm, but with the increase or decrease of weak electrical products and uses, it is suggested that the owner choose a weak electrical box with appropriate size according to his own needs.
There are generally two methods for weak electrical boxes: surface mounting means hanging on the wall or putting it in the corner, and concealed mounting means embedding the box into the wall, usually about 30cm from the ground. When installing, consider whether the wall thickness is enough to bear the box.
2. Weak current wiring mode: Most of the weak current wiring in parallel houses adopts the "star topology wiring" mode, that is, the parallel mode is adopted, and centralized management is carried out in the weak box.
This is an alternative to the past "bus topology". Parallel connection emphasizes that each line is independent, which can avoid the paralysis of the whole system caused by single point failure and facilitate the expansion of single line.
3. Determining the endpoint of the line is the same as determining the endpoint of the high-voltage structure. Before low-voltage construction, first of all, according to the low-voltage wiring design and the schematic diagram of this point on the wall, mark the position of the cassette at each point with a pencil, ruler or Mo Dou.
Except for special requirements, the height of the cassette is the same as that of the original high-voltage socket, and the height of the background music tuning switch should be the same as that of the original high-voltage switch.
If there are multiple cassettes, the distance between cassettes should be at least10 mm.
4. Determine the route and slot. According to the end point, determine the slotting route.
When determining the route, we should follow the principles of shortest route, no damage to the original high voltage and no damage to waterproof.
Determine the number of ducts according to the number of weak lines, and then determine the width of ducts; In general, the depth of the trunking is about 5 mm larger than the diameter of the conduit.
Use a cutting machine to cut a groove on the wall along the played ink line. Grooves need to be horizontal, flat and vertical, with uniform size.
5. Threading and sealing All weak lines must be laid through pipes, so it is necessary to lay conduits before threading.
Then install the wire box, install the panel, etc.
Finally, sealing the groove, pay attention to the wall and ground after sealing the groove shall not be higher than the plane.
Remember to clean the construction site and remove garbage after installation.
