DC power socket has many uses, usually used for household appliances, such as audio, computer, television and other common electrical appliances we need to use, it looks like a small part, but our electrical use will also have an impact. The role of copper in DC socket is to ensure smooth current and reduce the heat of the key components. Good quality power sockets are basically made of high quality copper.
DC power socket is a kind of special power and computer monitor to match the socket, it is composed of transverse socket, longitudinal socket, insulation base, fork type contact shrapnel, directional keyway, two fork type contact shrapnel located in the center of the base, into the vertical and horizontal arrangement are not connected. One end of the fork contact shrapnel is a connection port, which is exposed on the top surface of the base cylinder body for connecting the input power supply cord or soft cable. The other end of the fork contact shrapnel is composed of two elastic arms connected by the matrix, which is arranged in the insulation base socket in the direction of the DC plug insertion. It is used for the computer monitor to make it work normally. Generally speaking, according to the packaging mode of DC power socket can be divided into: SMD, DIP; According to the size of the center needle: 2.5, 3.0, 3.5; According to the use and divided into: Bluetooth, car, notebook and so on.
The DC power socket mainly includes a socket terminal, a shell and a plastic body. It is an improved DC power socket. Its set by this body splice terminal side cut set as can prevent the plug terminal rotating planar body, the plane body with plastic body relative to the edge of the plane body is fixed, the splicing terminals around a groove, a fixed fork piece side of the groove embedded groove combination, the socket body is equipped with the outside shell, shell has a clip on each side, The clip is pushed inward to clamp the plastic body is stable and fixed, the plastic body is provided with a slot, a conductive terminal and a conductive shrapnel embedded into the slot, when the power supply is connected with the top of the head to deduce the electric shrapnel state, the conductive shrapnel contact the conductive terminal. It has the function of opening and closing switch, in order to achieve the purpose of stability and good conductive safety effect, and has practicability.
Generally speaking, when we choose DC power socket, we mainly judge the quality of socket copper parts according to the following four standards: oxidation resistance, strong toughness, thick copper, less riveting. Thickness of copper sheet, improve the ability of current passing and reduce the resistance of copper piece itself. Strong toughness, especially applied to the DC socket part, not easy to deform. If socket is used for a long time, also can maintain appropriate clamping force, ensure that plug cover and plug are closely connected, reduce arc. Antioxidation, no rust, reduce the resistance caused by corrosion and heat problems. Less riveting, it is recommended to choose a single piece of copper to further reduce the fracture of the riveting part and rivet heating.
Second, dc power outlet in the connection, the first to consider the circuit, the current most of the circuit and the main circuit of NPN polar components, the circuit is power negative extremely common ground, so the electric equipment of dc interface is based on the negative side, so the power plug of the coat should be meet the power of the cathode. The main wiring steps of DC power socket are: first find out the fire line with a test pen, and turn off the DC power socket. Then, connect the fire wire to one of the two holes of the switch, and then connect a 2.5mm insulation wire from the other hole to the L hole of the three holes of the socket below and secure it. Then, find out the zero line is directly connected to the socket 3 holes in the N hole and secure. Then, find out the ground wire directly connected to the socket 3 holes in the E hole can be fastened.
