Power socket and power socket of electronic device

The utility model relates to a power socket and a power socket of an electronic device. The power socket comprises a body with a defined jack and a central terminal arranged through the jack, at least a first conductor and at least a second conductor. The first conductor is arranged in the jack. The second conductor and the central terminal are electrically connected. The first conductor and the second conductor respectively have a first springing part and a second springing part which are protruding and allows compression deformation. The jack is used for insertion of a plug. The central terminal is arranged through an inner hole of the plug. The connection state with the plug is kept by utilization of the springing effects and the compression characteristic of the first springing part and the second springing part. The power socket is suitable for plugs with different dimensions, and therefore convenience and practicality in use are raised.
