How should the pins of the DC socket be connected? Specific connection methods we give you a detailed introduction.
DC socket refers to a special socket matched with the power supply of computer display. It consists of longitudinal socket, transverse socket, fork contact shrapnel, insulating base, directional keyway and other components. The two fork contact shrapnel on the pin of DC socket are positioned at the center of the base, arranged vertically and horizontally but not connected with each other. DC socket pin fork contact shrapnel one end is the junction port, exposed on the top of the base, for connecting input power supply soft wire or soft cable, then how to connect the DC socket pin? What is the knowledge of DC socket pins? Next, let's follow the duplex electrons.
DC socket pin-application
With the continuous development of society and the continuous updating of science and technology, the DC socket pins are widely used in our daily life. Before we know how to connect the DC socket pins, we first know what the scope of use of the DC socket pins is. DC socket pins are used in many fields such as MP3, MP4, DVD, audio, digital camera, digital video camera, vehicle remote controller, point-and-roll door remote controller, mobile phone, telephone, on-board telephone, building equipment, PDA, TV, microwave oven, rice cooker, electric wind, electronic fat scale, electronic body scale, electronic kitchen scale, visual walkie-talkie, monitor, electronic toy, etc.
DC socket pins - Specifications
With the social progress, the market demand for DC sockets is increasing, so how to connect the pins of DC sockets? Different specifications of DC sockets have different pin wiring modes. Common specifications of DC sockets are: 0.5mm, 0.7mm, 1.0mm, 1.1mm, 1.3mm, 1.65mm, 2.0mm, 2.5mm, 3.0mm, etc. In the process of using the DC socket, we must pay attention to the protection of the pins of the DC socket. In the packaging of the pins of the DC socket, we must be scientific and reasonable, so as to avoid the distortion, loosening, tilting, scratching, bad electroplating and oxidation rusting of the pins of the DC socket, which will affect the normal use of the DC socket.
DC socket pins - technical specifications
With the continuous progress of science and technology, the technological level has been developed from point to point. In our daily life, DC sockets are widely used, so how to connect the pins of DC sockets? First, let's get to know the technical specifications of DC socket pins. Contact Resistance is less than 0.03mm_, rated load is Rated Load 30V DC 0.5A, insulation resistance is more than 100M, insertion force is: Insertion and Extraction Force 3N~30N, withstand voltage is: Voltage 500V, WithAC/min life is 5000 times. Temperature range: Temperature - 40 ~+70 ~C.
DC socket pin-link
DC socket pin connection is particularly important in the use of DC socket. I believe that most people do not know how to connect the DC socket pin. There are no dual electronics. This will give you a detailed introduction of the steps of pin connection of DC socket. The center of pin socket of DC socket is positive, and the edge of the socket is negative. Connecting MCU and socket core is connected with VCC. VCC is fixing the pin of the DC socket of the pipe to GND. The side is usually fixed and can be disconnected. It can be soldered independently when the pin of the DC socket is soldered, and it is not connected with other pins. The DC socket pin has two left and right feet, one zero connection and the other fire connection.
DC socket pin-fire rating
With the rapid development of economy, more and more people pay attention to the safety of power consumption in daily life. Because of the different pin styles, types and functions of DC sockets, there are also some differences in the fire protection level of the pins of DC sockets. When choosing the pin of DC socket, the insulator is burned with alcohol lamp or lighter. The result must meet the required fire protection grade. The definition of grade safety regulation is: UL94V-0 insulator stops burning in 10S and can't drip with solute; UL94V-1 insulator stops burning in 30S and can't drip with solute; UL94V-2 insulator stops burning in 30S and allows a small amount of solute to drip.
