Computer power outlet size? How to wire a computer power outlet

In our life, computer is very important electronic equipment. Only after the installation of the computer, can let us better use. So in the installation of the computer, the computer power outlet and so on, what are the specific provisions? We next take a look at the more popular computer power outlet size on the market. And I came to see it.

A, computer power outlet size?

What are the standards for computer power outlet size? As the dc socket use according to the different computer models vary, making the dc socket specifications are numerous, dc socket center pin: 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm. more common dc socket specifications are: 2.35*0.7TVdc plug, 3.0*0.1TVdc plug, 3.0*0.1TVdc plug, 3.0*0.1TVdc plug, 3.0*0.1TVdc plug, 3.0*0.1TVdc plug, 3.0*0.1TVdc plug. 0.1TVdc plug, 2.5*0.75TVdc plug, 3.5*1.1TVDC plug, 3.2*0.9TVdc plug, 4.0*0.7TVdc plug, 4.75*1.7TVdc plug, 3.5*1.35TV, 2.0*0.6TVdc plug 5.5*2.1TVdc plug, 6.5*3.0 TVdc plug, 5.5*2.5TVdc plug.

We can observe the computer power supply in this way. Power socket is widely used in our days, everywhere, such as MP4, MP3, DVD, stereo, rice cooker, microwave oven, TV, electric fan, electronic fat scale, electronic body scale, electronic kitchen scale, cell phone, car phone, telephone and other audio-visual products, digital products and household appliances in many ways. In addition, some will be used in medical equipment, fitness equipment, security products, computer products and so on.

Additionally, this is the current universal computer power outlet size. Power socket specification norms are many, different products require different power socket specification norms. Power socket specification specification is not the same as the primary type is not the same, the following is the introduction of a few Best Electronics typical, commonly used types of power supplies and the relevant specification drawings, specification drawings on the clear table clearly its relevant specifications.

Two, computer power socket wiring

Computer power socket wiring first step: DC low-voltage power plug is typically connected to the jacket ground, the inner core of the power input. As for that end of the positive pole negative pole! Is determined by the device circuit, the vast majority of current circuits are based on NPN polarity components of the main circuit! The circuit is to the power supply negative for the public **** grounded, so these electrical equipment DC interface is to the negative for the ground, so the power plug jacket should be connected to the power supply negative! The inner core is connected to the positive terminal.

Computer power socket wiring step 2: two-pole plug only zero fire, do not share the direction. Only three-pole has a direction, usually facing the jack, on the ground, left zero right fire. If there are only two wires, only zero fire, not ground. There are 2 two-hole, 1 three-hole five-hole socket, the back of the two-hole wiring hole with a wire and three-hole L, N pole connected.

Computer power socket wiring the third step: the general building under the cable buried depth of not less than 0.3 meters, softer or more complex surrounding environment, such as arable land, building construction sites or roads, etc., there should be a certain depth of burial (0.71 meters) to prevent accidental damage to the direct buried cable, if necessary, should be erected a distinctive sign.

In summary, I believe that now we have a more comprehensive understanding of the computer power outlet size. Then in our computer power socket installation, we can start from the above installation steps, the computer power supply installation, I believe that this will help the majority of consumers.
