DC sockets need to be welded when they are used and installed. In terms of specific welding methods, we will give you a detailed introduction.
DC socket is a kind of DC socket which can be installed and plugged into circuit board to connect AC adapter. Because the pins do not match the pitch of IC, they can not be directly installed in the 2.54mm jack of universal board. A 1.1-1.6mm borer with diameter sound is needed to drill holes in the circuit board.
If there is a small drill with a sound of about 1.1mm, it is best to buy a manual drill in a shopping mall for about 800 yen. As shown, the circuit board jacks are opened, and the holes are further widened with pliers and tool knives.
After the opening work is completed, the pins of the socket are welded as shown. When there is no welding at the opening, bend and fix the pin of DC socket, and put copper wire (tin plating) around it for welding.
When connecting an AC (DC) adapter, the polarity of the DC connector socket used must match the polarity indicated by the AC adapter. It is necessary to carefully confirm whether the central pin is negative or positive.
Moreover, when AC adapter is not set to rectifier, the output is no longer DC (DC) but AC (AC), there is no AC function. The nameplate logo of the adapter is usually as shown. The content of the nameplate needs to be carefully examined to confirm the pin polarity. The AC adapter central pin used in this time is positive, the DC socket back pin is positive, and the pin below the center is grounding wire.
