Home improvement weak electricity installation method skills

The installation of the circuit during the decoration is divided into strong points and weak electricity. The functions of weak current and strong power are different, so the installation of weak current and strong power are still somewhat different. For example, household telephone lines, network cables, and television lines are all weak.

First, the introduction of weak electricity

The difference between weak current and strong electricity is mainly the difference in use. Strong electricity is used to transmit power energy, that is, electricity. Weak current is used for information transmission and control. The characteristics of strong electricity are high voltage, large current, high power and low frequency, which are harmful to people. The weak current is characterized by low voltage, small current, low power and low frequency, which is not enough to cause fatal damage to people. The air conditioning line, lighting line, and socket line in the home belong to the strong electric line, and the telephone line, the television line, the network line, etc. belong to the weak electric line.

Second, weak electricity installation planning

1. Follow the principle of practicality and moderate advancement

The weak electricity planning of the home should follow the principle of “practical, appropriate and advanced”, and consider the potential demand according to actual needs and consumption capacity, and choose a suitable renovation plan. Try to consider as much as possible, because if you want to increase later, you can only take the bright line, affecting the beauty of the home, so it is better to try to get it in one step.

2, design weak electricity layout

Generally, the formal decoration company will provide the layout diagram of the weak electricity transformation. The layout of the layout is made in accordance with the needs of the owners, and the owners should pay attention to the preservation. This not only helps to prevent the hidden troubles of the circuit system within certain limits. At the same time, it is also beneficial to update or upgrade the line in the future.

Third, weak electricity construction process

In fact, the focus of home improvement weak electricity is in the design layout, and the installation is generally carried out together with the strong electricity, and the installation process is basically the same, that is, according to the steps of positioning, slotting, wiring and the like.

1. It is recommended to configure centralized management of weak boxes.

At present, strong electricity in home improvement generally solves centralized control and management problems through distribution boxes, while most people's weak electricity lacks unified management. As the demand for weak electricity increases, weak current lines will become increasingly complex, so it is necessary to centrally manage weak currents. The owner can install a weak electrical box similar to a strong electrical box to centrally manage and maintain the telephone, fax, computer, television, security monitoring equipment and other network information appliances in the home.

(1) Installation of weak electrical box

The general size of the home weak box is 320 x 260mm, but with the increase and decrease of weak electricity products and uses, it is recommended that the owner choose a suitable weak box according to their own needs. Weak electrical boxes generally have two methods: wall mounted and concealed. The wall mounted is mounted on the wall or placed in the corner. The concealed box is embedded in the wall. It is usually installed around 30cm from the ground. Whether the thickness is sufficient to carry the case.

2, weak wiring method: parallel

Most of the weak current wiring of the family adopts the "star topology wiring" method, that is, the parallel connection is adopted, and the centralized aggregation is concentrated into the weak electric box to implement centralized management. This is a substitute for the “bus topology” in the past. Parallel emphasis is that each line is independent, which can avoid the flaw of the whole system caused by a single point of failure, and facilitate the expansion of a single line.

3. Determine the line termination point

As with the construction of strong electricity, before the weak electricity construction, firstly, according to the design drawing of the weak electric wiring, combined with the point diagram of the wall, the position of the cassette at each point is marked with a pencil, a ruler or an ink fountain. Except for special requirements, the height of the cassette is the same as that of the original strong electric socket, and the height of the background music tuning switch should be the same as the height of the original high-power switch. If there are multiple cassettes together, the distance between the cassettes is at least 10mm.

4, determine the routing and slotting

According to the terminal point, determine the slotting route. When determining the route, the principle of the shortest route should be followed, the principle of strong electric power should not be destroyed, and the principle of waterproofing should not be destroyed.

The number of conduits is determined according to the number of weak wires, and then the width of the conduit is determined; the depth of the conduit is generally about 5 mm larger than the diameter of the conduit. Use a cutting machine to cut the wire trough on the wall surface along the well-printed ink line. The trough needs to be horizontal and vertical and uniform in size.

5, thread sealing groove

All weak wires must be laid through the pipe, so first it is necessary to lay the pipe and then thread the wire. Then install the wire box, install the panel, and so on. Finally seal the groove, pay attention to the wall surface after the sealing, the ground should not be higher than the plane. After the installation is complete, remember to clean the construction site and remove the garbage.
