Because 1 18 switch has no reasonable spacing between strong and weak current, and the distribution of strong and weak current is generally unreasonable, it is easy to have the problem that strong electromagnetic field affects weak current reception, so the 86 switch does not exist, and there are many brands to choose from. Now all the multi-function socket switches are 86 types.
Type 86 socket means that its specification is 86MM*86MM. Type 86 socket is square. The size specification is 86mm*86mm. There can be one unit, two units or three units of functional parts on it.
1 18 wall switch socket is a simple structure and widely used electrical switch. It is a wall switch that can be combined at will, which is very decorative.
1 18 switch socket has a long appearance and is divided into large, medium and small models. Its functional parts (switch, socket, telephone, TV and computer) and panel can be combined at will. 1 18 The biggest feature of the wall switch socket is that it can combine functional components at will, which greatly facilitates the use of users. In the process of installation and use, we should also pay attention to the mutual interference between high and low voltage functional components, and consult manufacturers and professional engineers and technicians.
Compared with Type 86, Type 1 18 has the following ten defects that cannot be ignored:
The sockets of 1 and 1 18 panels are mostly multifunctional plugs, and the internal current-carrying copper sheets are complicated in structure. In order to adapt to the insertion of different plugs, the contact surface between the internal copper sheet and the plug can not be maximized, even if the contact surface is small, the clamping force of the copper sheet on the pin is not enough. It is ok for low-power appliances such as chargers and desk lamps, but today, with many kinds of appliances and high power, this kind of socket will bring hidden dangers of electricity consumption, which will easily lead to contact heating and even burn out the socket plug.
2. Due to the complicated processing and structure of internal copper sheet, its mechanical strength and service life are generally short. Some middle and low-grade factories, especially small factories with miscellaneous brands, have rough processing, and the copper sheets are not punched in place or bent excessively, which makes some copper sheets in the jack irregular. The consequence is that the contact between the plug and the socket is not in place, or the plug is too loose and too tight to be inserted, which will affect the life of the socket and the plug for a long time.
3. This kind of multifunctional socket seems to be easy to use, and can adapt to plugs with different pin shapes, but on the other hand, it is not. After a socket module is plugged into a three-hole plug, it can't be plugged into two holes, so it can only be plugged into another module on the panel. The 86-type five-hole panel is equivalent to one of its modules, but the 86-type panel can be plugged with three-hole plugs and two-hole plugs at the same time (at least the Zhengtai switch socket is like this).
This kind of panel is better and more expensive, but a large part of the cost does not come from workmanship, materials and design. 1 18 models are generally lower in cost performance than 86 models of the same grade.
5. Due to the limitation of the panel size, the switch buttons can't be made longer and larger in the vertical direction, so the touch of the buttons is generally different from that of the 86-level switch.
6. Because of the module structure and the size of internal copper parts, the safety protection doors of most sockets are useless, and you can easily insert things by poking a hole. Families with children should attach great importance to electric shock; Moreover, regular sockets with protective doors need to be poked on both sides to insert things. Of course, a few big-name 1 18 panels can also do this.
In terms of stress, Type 7 and Type 86 are more stable (square is better than rectangle) and less prone to deformation when plugged and unplugged. 1 18 socket, combined with its own structural weaknesses, is prone to poor plugging and unplugging. Sometimes when the panel is deformed slightly, the socket module is pushed into the cassette, and even when the plug is pulled out, the module is often taken out (poor quality). Because of the size of the cassette, the heat dissipation in the cassette is not smooth, which is easy to accelerate the aging of the panel and reduce the safety factor.
8. As we all know, generally speaking, the position of the switch is about 1 m 4 from the ground, and the position of the socket is about 30 cm from the ground. So how much should "one switch and one plug" (a small panel of one switch and one socket) be off the ground? From the ground 1.4m, the socket is inconvenient to use (the wires of electrical appliances should be lengthened). 30 centimeters from the ground? Then you have to squat down and press the switch, not to mention "one open and one plug", "two open and one plug" and "two open and two plugs" are all on the list made by the electrician, which is a dime a dozen.
9. Three plugs and a look (installing three sockets and a TV film on a panel) are widely used and are generally installed on the TV wall (behind the TV). Let's look at the security issue. 1 18 strong and weak electricity are in the same cassette, and they are very close, very close, or because the cable is not tight, or because of a fault, the network cable or TV cable is ignited. Type 86, on the other hand, has a strong current in one cassette and a weak current in the other cassette, so it won't be "intimate contact" even if double cassettes are used, which is safe and worry-free.
10 and 1 18 have high requirements on technology and installation attitude, and high maintenance costs. For example, there are usually one or two four-plug sockets on the kitchen stove, and a jumper is needed behind this four-plug socket. When it breaks down or changes itself in the future, it is difficult for people without any electrician knowledge to start. Moreover, after all, the switches are installed manually, so it is difficult to ensure that each switch will not go wrong, and it is also difficult to ensure that the screws at the terminals will not go wrong, especially for cheap and miscellaneous products, which are easy to slip, loosen or even break the screws, so troubles and troubles will come unexpectedly. Type 86 high-voltage socket does not need jumper wires, and a socket is a "molding module". Generally, there are three eyes, namely live wire, zero wire, ground wire and three ports. As long as they are not idiots, they will be wired and installed in metropolis.
