Take a look at DC power connectors

General power connectors are specifically designed to transfer power from one device to another or from one point to another point of the same device. These connectors typically have higher voltage, current, and temperature ratings. Suzhou connector manufacturers Huichengyuan to explain the next DC power connector knowledge! The DC power connector is a type of DC connector that is used specifically to transmit DC power to the connector of the device. They have a smaller current and voltage rating than other power connectors. They are primarily used for 12 VDC. They are electronic devices with low power consumption. These connectors are available in male and female types. Their male pins typically have a cylindrical structure with internal and external contacts separated by an insulating material. The male DC connector is commonly referred to as a DC Jack, while the female DC connector is referred to as a DC receptacle. The DC Jack is connected to a wire that flows down from a DC adapter or battery eliminator. The DC socket is soldered into the circuit board to which the DC socket is to be connected. The DC socket is usually mounted on the edge of the PCB, so there is no other component to prevent the handcuffs from entering the connector. You can always find the ON/OFF switch and the power indicator LED next to the DC outlet. The DC socket is a simple cylindrical structure with two contacts separated by an insulating structure, but the DC socket is not so simple. Even though the DC Jack has only two contacts, most DC outlets have three pins. The outer cylindrical contact is GROUND and the inner pin is positive. While most boards have batteries attached, we can still plug in an external DC adapter to operate the circuit. The three-prong structure of the DC socket 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 the 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 battery GROUND is connected.
