[0002] With the continuous advancement of electronic technology, our dependence on electronic devices is increasing. Among them, the power plug, as a key connection part of electronic devices, is of self-evident importance. However, the traditional DC plug has gradually revealed its limitations in design and function, especially in terms of power stability, safety and intelligence, which can no longer meet the high standards of modern electronic devices for power connection.
[0003] Although traditional European standard DC plugs can provide stable power connections for electronic devices, in some cases, the docking of European standard DC plugs may not be stable enough. Since there may be slight differences in the fit between the plug and the socket, this may cause the plug to loosen or fall off easily after docking, thus affecting the stability of the electrical connection; frequent plugging and unplugging operations may cause wear on the contact parts of the plug and the socket, which in turn affects the tightness of the docking and the reliability of the electrical connection; after long-term use, wear may cause poor contact, increased resistance, and even sparks and other safety hazards; some European standard DC plug designs may require a specific insertion direction. If the user inserts the plug in the wrong direction, it may cause docking failure or damage the plug and socket. Utility Model Content
