DC-026 is a very practical power socket, its characteristics are more obvious. First of all, the compact size and simple design of the DC-026 socket can be used in a wide range of electronic devices such as digital cameras, wireless routers, and power adapters. Secondly, the DC-026 socket has the characteristics of small contact resistance, can provide a stable power interface, can provide a stable driving power to the equipment, to ensure the normal operation of the equipment. Basic principles of DC power sockets Power sockets rely on electrical contact to transfer electric energy, and the transmission of electric energy will inevitably cause the temperature rise when the plug and socket cooperate. When the load increases or the ambient temperature decreases, the current in the DC power socket increases sharply. As a result, the temperature rises too high, causing dangerous accidents such as fire. Therefore, overload protection must be implemented on the DC power socket. Take corresponding measures according to different circumstances. If the temperature rise under full load reaches the maximum required by the technical parameters, the plug and socket cooperate in the transmission of electric energy in the process of smooth operation.Video and audio products, notebook, tablet, communication products, household appliances Security products, toys, computer products, fitness equipment, medical equipment Mobile phone stereo design, earphone,CD player, wireless phone, MP3 player, DVD, digital products The use of DC power socket: such as ordinary air conditioning indoor units are equipped with an emergency switch, that is, the quality of the air conditioning remote control test, if the emergency switch can be turned on, you should choose to change the remote control, power socket power failure or cut off the power line. In some special cases, such as emergency situations such as power failure, you need to pull out the power plug to work normally. In this case, you should try to use DC power. In addition, the DC power socket can also be AC power supply. Ac voltage is harmless to human body. Of course, not all electrical equipment uses DC power supply. Ac power is used in many devices and household appliances, especially in lamps, washing machines, refrigerators and other equipment. Ac power is transmitted directly from the power grid through the power outlet.
