DC socket is how to connect to the power supply, the specific operation methods we will be detailed in the following section.
The DC socket is a DC socket that can be installed and plugged on the circuit board to connect AC adapters. Because the pins do not match the IC pitch, they can not be directly installed on the universal board 2.54mm.
In the jack, a hole drilling device with a diameter of 1.1 to 1.6mm is needed to open holes in the circuit board.
If a small drill with a sound of about 1.1mm is preferable, you can buy a manual drill for about 800 yen at a typical shopping mall. As shown in the following figure, the circuit board jack is used.
Open the hole and use the pliers and tool knives to further Kong Kuokuan.
After the opening work is completed, the pin of the socket is welded. When the hole is not welded, bend and fix the DC socket extension pin, surrounded by copper wire (tinned) for welding.
Method for connecting DC socket to power supply
When connecting to an AC (DC) adapter, the polarity of the DC connector socket used must match the polarity indicated by the AC adapter.
Moreover, when the AC adapter is not set for rectification, the output is no longer DC (direct current) but AC (alternating current), where no AC function is used. The nameplate signs of the adapter need to be examined carefully.
Nameplate contents confirm pin polarity. The AC adapter center pin used this time is positive, DC socket back-end pin is positive, the center below the lead for the ground wire.
