DC socket looks like a very remote word, but it's just because we don't usually call it that way. As a special socket for matching the special power supply of computer monitors, this kind of socket is very common in our life.
The components of the DC socket are more complex than the ordinary sockets. It is made up of oil transverse jacks, longitudinal slots, insulated base seats, fork type contact shrapnel and directional keyway. The center part of the pedestal is provided with two forked contact shrapnel, and two shrapnel are arranged vertically and horizontally even though they are not connected.
The function of the two ends of the fork type contact projectile is different. The terminal is connected to the top of the base cylinder. The main worker is connected to the input power cord or the soft cable; and it is set in the insulated base socket of the DC plug and the other is composed of two elastic arms interconnected by the matrix. The function is to allow the computer display to be able. Normal operation.
In addition, there are two main types of DC sockets, one is the SMT patch package, the other is the DIP plug-in package. When choosing, you should first distinguish the difference between the two and make specific decisions.
What is the function of the DC socket
Whether it is from the characteristics of the socket itself, or from the scope of the socket, DC socket has a greater influence in our life. But do you know the specific functions of this socket?
A lot of friends have heard that this is a plug in a computer display power line, which may be thought to be suitable for use on a computer, but in fact, it has a very large role in addition to the computer. For example, the following products can use the DC socket:
First, digital products such as digital cameras and digital cameras.
Second, all products that can provide communication for us, such as mobile phones, iPad, telephone, building equipment, etc.
Third, infrared remote sensing products, such as vehicles, security doors, and rolling doors, can be used.
Fourth, electrical appliances at home, such as microwave ovens, electronic scales, rice cookers, televisions, etc.
Fifth, public places need to use monitors, video walkie talkies and other security products.
Sixth, common electronic toys and other toy products;
Seventh, the medical equipment used in hospitals, gym and family running treadmill, massage chair, and computer products such as cameras and recording pens.
How to choose the DC socket
Usually, the DC socket used on the computer is matched with the power cord, and generally does not need to be purchased separately. But the computer has been used for a long time. DC sockets will also need to be replaced because of various reasons. So, how do you pick it up?
First, according to the computer power line selection
The sizes and sizes of power lines of different types of computers will be different. For example, the power lines of notebook and desktop computers are different. When choosing DC socket, the power cord of the computer should be compared to the store. Only the model is selected correctly, can the two match.
Second, don't ignore the brand
Try to choose the same DC socket with the same computer brand, so that socket and power cord can be matched. If you do not want to buy the same brand, you should also choose regular brand products, and you can not choose products without license because of the low price.
Third, pay attention to the color of the socket
The color of the DC socket is black and white and gray. In order to ensure that the visual effect of the socket and the power line is uniform, the socket with the same color of the power line should be selected.
Fourth, check the quality of the socket
The quality of the DC socket is good, mainly depends on the circular copper parts and insulation layer inside the socket. High quality socket copper parts are made of copper tin phosphor cyanide with good elasticity. The insulating materials of high quality are mostly good flame retardant materials.
Precautions for installation of DC socket
Ordinary outlets, in addition to the purchase must pay attention to some of the necessary skills, installation is more important. The use of DC sockets also requires attention to installation problems, such as the following:
The DC socket also has three phase lines, including zero line, fire line and grounding wire. Installation is also installed in accordance with the principle of "left zero line, right fire line, middle grounding wire". This point needs to be clearly understood before installation, otherwise it will be easily mistaken.
Although the DC socket is also a three hole socket, it has a special protective zero connection jack. If it is installed, connect the wiring terminal of the zero insertion socket to the zero line in the socket of the socket of the elder sister, so it is easy to have an electric shock accident. Therefore, when installing DC socket, we should ensure that the ground socket is connected with the special protective earth wire.
To sum up, when installing a DC socket, if you have no experience in installing a similar socket, we should try to install and maintain a professional computer to avoid some safety problems. If you really want to do it yourself, it is recommended for experienced people to watch and make adjustments and guidance around them.
How to use three pins in the DC socket
The DC socket has 3 pins on the panel, and the pin has an inneglecting function to the socket. So, how do these 3 pins use it?
Most DC sockets have three pins, but in the actual installation and connection, it does not need to be all connected. It is only enough to connect two pins.
When connecting the socket, the positive and negative poles should be determined first. Usually, the center of the pin socket is the positive pole, and the edge of the pin is negative. even
