General DC connectors are specifically designed to transmit power from one device to another or from one point to another point on the same device. These connectors usually have relatively high voltage, current, and temperature ratings. The following is an explanation of a common type of power connector called a DC power line connector.

DC power line connectors are a type of DC connector that is specifically designed to transfer DC power to a device. They have a lower current and voltage rating compared to other power connectors They are mainly used for 12 V DC. they are common for low-power electronic devices. These connectors have two types: male and female. Their male pins usually have a cylindrical structure with internal contacts separated from the external contacts by insulating material. The male DC connector is usually called a DC jack, while the female DC connector is called a DC socket. the DC jack connects to the wires that flow down from the DC adapter or battery eliminator. The DC jack is soldered into the circuit board to which the DC jack is to be connected.
The socket is an important part of the DC connector. The DC jack is usually mounted on the edge of the PCB so there are no other components to prevent the pins from entering the connector. You will always find the ON / OFF switch and power indicator LED next to the DC jack. DC jacks are a simple cylindrical structure with two contacts separated by an insulating structure, but DC jacks are not that simple. Even though the DC jack has only two contacts, most DC sockets have three pins. The contact points outside the cylinder are grounded. The inner pin is positive.
The circuit is the most important part of the DC battery connector. The quality of this part determines the quality of a whole power connector. Although most boards have a battery attached, we can still plug in an external DC adapter to operate the circuit. the three-pin construction of the DC jack is used to separate the GROUND terminal of the battery from the GROND terminal of the DC adapter. The positive terminal of the battery and DC adapter can be connected to PIN 1 of the DC socket. pin 1 and pin 2 supply power to the PCB. pin 3 is where the GROUND of the battery is connected.
