Smart home wiring commonly used materials

To understand the smart home, to start with the most basic smart home wiring commonly used wire, the following my home smart will learn together with everyone about smart home wiring materials knowledge!

The so-called smart home started from the wiring, this really comes up to the idea. In addition to smart home wiring needs to be designed in accordance with integrated wiring standards, as an end user, it is also necessary to understand the materials and materials used in home wiring. Now we come to understand the basic products of home wiring.

1. Home wiring box. The home wiring box is the center of the home wiring management equipment, and usually connects and manages the module configuration box, communication module, video module, network module, sound module, system socket, cable, home intelligent management system, etc. If the home AV center equipment More and equipped with special cabinets, these devices can be placed in a standard cabinet together with home wiring equipment.

2. RJ45 module. There are four basic module sockets. The 8-pin modular socket is usually called "RJ45" and the 6-pin modular socket is usually called "RJ11". "RJ" refers to registered outlets, each of which can connect differently configured RJs. For example, a 6-pin socket can connect RJ11 (1 pair), RJ14 (2 pairs) or RJ25C (3 pairs); an 8-pin socket can connect RJ61C (4 pairs) and RJ48C. The 8 cores (Keyed) can connect RJ45S, RJ46S and RJ47S. The fourth modular jack is a variation of the 6-pin, which is a voice device designed by DEC to connect DEC. The integrated wiring module is used to terminate the cable and the effective connection with the jumper. Modules are used in distribution frames or home wiring boxes at the exit of the information panel.

3. Twisted pair. The twisted pair consists of two insulated copper wires, typically 1 mm in diameter. The two wires are twisted together in order to prevent their electromagnetic induction from interfering signals in adjacent pairs. The current twisted pair cable generally includes four twisted pairs, specifically white orange/orange, white blue/blue, white green/green, white brown/brown. The common twisted pair has box and shaft packaging and is 305 meters (1000 feet) long. At present, the domestic market is the most sold 305 meters cable length, carton packaging of the ultra-five twisted pair.

4. Jumper. Also known as network cable. The copper jumper in the wiring is actually a short twisted pair, and the two ends are crimped together to complete the connection between the module, the distribution frame and the active equipment. The common length of the jumper is 1 meter and 2 meters. , 3 meters, 5 meters, 10 meters. Home wiring is recommended to use the original jumper, the original jumper process is rigorous, can withstand repeated insertions and withdrawals.

5. Crystal head. It is only a part of the finished jumper. When the home wiring, the original jumper may not meet the length and other requirements. The user may purchase the crystal head and the cable by using a dedicated crimping tool.

6. Optical fiber. An optical fiber is a small, flexible medium that transmits a light beam, centered on a light-transmitting glass core. Fiber optic cable consists of a bundle of optical fibers, simply referred to as fiber optic cables. Optical fiber cable is the most effective transmission medium in data transmission. Its advantages are: wide frequency band, good electromagnetic insulation performance, and low attenuation. Commonly used optical cables include: 8.3μm core, 125μm outer single-mode optical cable, 62.5μm core, 125μm outer multimode optical fiber cable, 50μm core, 125μm outer multimode optical fiber cable, 100μm core, 140μm outer multimode optical fiber cable.

Fibre-to-the-home is a term used more recently to refer to the access network that connects fiber-optic networks to the average home. From the perspective of technology development, fiber to the home (FTTH) is the ultimate solution for access networks.

7. Audio and video cables. There are many audio and video cables involved in home entertainment systems: audio cables include FM-amplified antennas, analog signal cables, and fiber-optic coaxial digital cables. Video cables include composite video and S-Video cables. Coaxial cables used in cable TV are common RF cables. , There are professional speakers and so on. Pay attention to the proper handling of the wiring, such as the power cable and speaker cable can not be tied together when the wiring, because the AC will affect the signal; wiring can not tie, otherwise it will affect the tone; too long to change the wiring; many wiring is directional, do not Wrong answer.

8. Coaxial cable. The coaxial cable is made of hard copper wire and covered with a layer of insulating material. This layer of insulating material is surrounded by a densely woven mesh conductor, which is covered with a protective material. There are two widely used coaxial cables, baseband coaxial cable and broadband coaxial cable. The broadband cable is used in the urban or residential cable television network when accessing the home and in home television systems.

9. Patch panels and panels. The patch panel is versatile, economical and practical and can be used for horizontal and vertical cabling or for direct connection to hubs and horizontal cabling systems. With 12, 24 and 48 ports to choose from. The connection terminal is 110IDC, both front and rear labels, easy to identify. The standard 19-inch rack type distribution frame is usually used for commercial wiring. The home wiring can use six small units, saving space, easy installation, low cost, and can be installed in a small home wiring box. The panel is a widely used accessory. When the cable is routed, the panel is used to install the fixed module at the information exit location. Domestically, the 86 standard back box is usually used, and there are two kinds of single-port and dual-port. The common wiring panel is mainly installed with computer and telephone information outlets, and the multimedia information panel even has computers, telephones, CATV, and audio interfaces.

The smart home wiring standards, in addition to the TIA/EIA570A standard, there is no other domestic standards and corresponding technical specifications. Due to the access to the network information of most homes, it is provided by different operators, both twisted-language wire access, CATV coax, and different broadband access (LAN) and indoor automation control. . Therefore, the home integrated wiring needs to support the above information functions, and all network information of different standards and interfaces is centrally managed to implement unified wiring.

Mini Flap Disc

flap discs are widely used in automobiles, stainless steel products, metal products, glass manufacturing and other industries, and have special effects on welds, solder joints, flash, rust removal and surface polishing. The reason why the Flap Disc is so widely used is because it has five advantages that cannot be ignored:

1. The flap disc blades have high hardness, high strength and strong grinding ability during use.

2. The flap disc has low noise, low vibration and long service life during use.

3. The flap disc has strong wear resistance and long service life.

4. It is not easy to generate heat and burn parts during use.

5. The use of flap disc can improve work efficiency.
