The installation and connection methods of DC sockets are not as difficult as you think.
DC socket installation and connection method is not as difficult as you imagined, only a systematic look, can easily deal with the details of the details in the following.
The DC socket is a DC socket that can be installed and plugged on the circuit board to connect AC adapters. Because the pin is not matched with the IC tooth distance, it can not be directly installed into the jack of the universal plate 2.54mm. The hole of the diameter 1.1 to 1.6mm should be used in the circuit board.
If a small drill with a sound 1.1mm is best, of course, a manual drill can be bought at about 800 yen in the general shopping center, open holes for the circuit board jack, and further Kong Kuokuan with pliers and tool knives.
After the opening work is done, the pin of the socket is welded. When there is no welding at the opening, bend and fix the pin extended by the DC socket and weld the copper wire (tin plating) around.
The method of connecting the power supply to the DC socket
When connecting the AC (DC) adapter, the polarity of the DC connector socket must be consistent with the polarity indicated by the AC adapter. It is necessary to carefully confirm whether the center pin is negative or positive.
Moreover, when the AC adapter is not set to rectify, the output is no longer DC (DC) but AC (alternating current), where no AC function is used. The nameplate mark of the adapter is usually shown. You need to take a closer look at the nameplate content and confirm the polarity of the pin. The AC adapter center pin used is positive polarity, the DC socket rear end pin is positive, and the pin below the center is the grounding wire.
