DC socket is so connected to the power supply, the key issues should be focused on solving, to solve the problems of electrical components, and can give you instructions on installation and selection, so the following is the main content.

The socket is a DC socket that can be installed and plugged into the circuit board for connecting AC adapters. 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 general shopping mall for about 800 yen. It opens the circuit board jacks and further widens the holes with pliers and tool knives.

After the opening work is completed, the pins of the socket are welded. 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.

Method of Connecting DC Socket to Power Supply

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 of the adapter is usually shown in the following figure. The contents of the nameplate need 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.

This is the problem of DC socket connecting power supply. I hope you can understand these problems.
