In our daily life, I believe that a lot of people will come into contact with different kinds of plugs every day. There are phone plugs, earphone plugs, power plugs, audio and video plugs, DC plugs and so on. Do we know enough about DC plugs? What are the components of the DC plug structure? What is the connection between the DC plug and the DC socket? How does the DC socket make up?
Although we often use DC plugs and sockets in our lives, we do not know enough about them. DC plug is used in household appliances: TV, electromagnetic stove, electric cooker, electric fan, computer and so on. Then its corresponding DC socket is composed of directional keyway, fork type contact bullet, insulating base, longitudinal socket, transverse socket. The two fork type contact shrapnel is positioned at the center of the base, vertically and horizontally. It's not connected. One end of the fork type contact shrapnel is a junction, which is exposed to the top of the base cylinder for connecting to the soft wire or soft cable, and the other end of the DC socket is composed of two elastic arms interconnected by the matrix.
The components of the DC socket must be sufficiently flexible, and the plugs have sufficient contact pressure to ensure that the DC plug is firmly inserted. Socket plug should also be resistant to corrosion and wear resistance to ensure that the plug and socket part of the DC plug is in good contact; at the same time, the plug can not be rotated to the plug, otherwise the insecurity and influence of the insertion performance will be produced; the flexible wire fixer of the converter will withstand normal tension and torque to prevent electrical shock from occurring. Therefore, when DC plugs and sockets are inserted, the insertion surface must be basically tight.
