question: I didn't sign up for the tonghuashun account. I used "tonghuashun Tiantong default user" to log in. Does this have anything to do with it? I downloaded it from the website of the securities company. Should it be ok
you can download it from the website I gave you! That's the official one.
The 120 type switch panel has four sizes:
120 mm x 74 mm, which can hold one or two function parts, also known as small box; 156 mm x 74 mm, which can hold three functional parts, also known as the middle box; 200 mm x 74 mm, can hold four function parts, also known as big box
120 mm x 120 mm, it can hold four functional parts, also known as square box. This is special, especially large, which is a square. The square switch panel is about the size of a palm. It is the most commonly used panel in China with the most styles. Its length and width are 86mm and x86 mm, which is also our national standard

attention to purchase
1. Choose the channel
when consumers buy power sockets, they should not be greedy for cheap, it is better to buy them in regular large chain stores, hypermarkets or electric appliance cities, and keep the shopping voucher
The style and color of the switch should be consistent with the overall style of the interior. For example, the overall tone of the interior decoration is light color, you should not choose black, brown and other dark switch. Moreover, the manufacturer and proct information of qualified sockets are complete, while some unqualified sockets are poorly packaged Third, the hand feeling can be distinguished from weighing, repeatedly pressing the switch, testing the plugging force and pulling the power cordthe two pole plug, that is, the live wire (phase wire) and the zero wire in the corresponding two hole socket, forms a complete current circuit. The bottom two pins of the three pole plug correspond to the live wire and the zero wire as the two pole plug, and the top one is the grounding pin, which corresponds to the ground wire on the three hole socket
according to the electrical standard, for electrical appliances whose shell is metal conctor, a three pole plug must be used to provide grounding protection when the metal shell is accidentally charged (the current is grounded, and the resistance of this circuit is almost 0. According to the principle of electricity, the current passing through the human body tends to be infinitely small, thus forming a protective effect). In household appliances, three pole plugs are mainly used in refrigerators, washing machines, rice cookers, microwave ovens, range hoods, electric water heaters, vacuum cleaners, computers and monitors, air conditioners, etc. Others, such as hair dryer, TV, DVD, desk lamp, are generally bipolar plugs< In the past ten years, there have been many new types of household appliances in our daily life, such as electric water heaters, indoor humidifiers and so on, but no one can estimate how many appliances will appear in the next ten years. Therefore, in the home decoration switch socket installation, when there is a certain reserved space
in the basic household stage, the consumption of switch and socket can be calculated by one panel per 2 square meters of indoor area. For example, if the indoor area is 100 square meters, 50 switch and socket panels can meet the basic demand of power control (including all kinds of conventional switch and socket, weak current information socket, etc.)
considering the reserved space, in recent two years, more and more decoration owners calculate the total consumption with a panel switch for every 1.5 square meters of indoor area. As the same kind of residence with an indoor area of 100 square meters, the total consumption of switches and sockets is about 66. Compared with the basic home, more than ten additional switch sockets are mainly used for:
1. Double control switches in living room, bedroom and aisle
2
3. One spare five hole socket is installed every 2.5m
4. Internal socket of kitchen operating table or cabinet (for disinfection cabinet, oven, microwave oven, etc.)
5. Add computer information socket in the living room, and a TV socket in the dining room if possible
6. Other locations that the owners need to control or take power according to their indivial needs
Introction to telephone plug, computer plug and TV plug. It is composed of panel and docking mole. The mole port can be connected with the corresponding plug, and the rear part is connected with the signal transmission line in the cassette to realize the signal transmission
telephone signals are divided into analog signals and digital signals. Ordinary telephone is analog signal, transmission only need two core lines and moles, so the early telephone plug many only two core. The digital signal transmission equipment such as program-controlled telephone or ISDN telephone needs four core lines and moles. Because the four core mole can be compatible with two-core signals, the four core mole is generally used in the market at present, and the price is slightly higher than that of the two core telephone socket
the computer network signal generally adopts 8-core data cable and mole (4-core is actually used). In terms of transmission performance standards, the current home mainstream is super-5, and the average transmission speed can reach 100M / S (the maximum transmission distance is 105m, and the maximum peak value is 155m / s). Due to the super class 5 transmission technology has been very mature, the current household computer sockets generally use super class 5 mole. With the continuous emergence of category 6, super category 6 and even category 7 data transmission technologies and procts, higher standard computer sockets will be used in some important or large data transmission application environments (such as government agencies, network companies, etc.), and such procts are far better than super category 5 procts in data transmission, anti-interference and other performance
TV signals are also divided into analog signals and digital signals. Analog signal is still widely used TV signal, digital signal can transmit a wider range of frequency, so it is the direction of future development. At present, many cities are carrying out two-way transformation of cable TV lines, that is, replacing the previous analog signal line (75 Ohm) with digital signal line (50 ohm). After transformation, the line network can provide cable internet broadband service on the one hand, and on the other hand, it is also the necessary hardware condition of interactive digital cable TV on demand system in the future. Correspondingly, there are two kinds of TV socket: ordinary TV plug and broadband TV plug. Ordinary TV plug-in can only transmit analog signals. Broadband TV plug-in can transmit both analog and digital signals.
