Problems solved by technology

[0004] 1. Generate sharp discharge and high heat, which will cause damage to electrical appliances;

[0005] When the plug structure of the prior art is electrically connected, when the conductive terminal 13 penetrates into the body of the aforementioned power base 20 and gradually approaches the top of the conductive slot 21, the tip of the conductive terminal 13 is often caused by different voltage fluctuations, variable currents, or air. Moisture and other factors lead to instantaneous tip discharge, that is, a powerful arc is generated instantaneously, thereby generating high heat and even locally generating instantaneous high temperature, resulting in melting of the plastic shell of the aforementioned power base 20 body, and causing corrosion of conductive metal The situation will make the surface of the conductive contact rough, increase the resistance, and even damage the structure causing more serious disasters; and the instantaneous current will damage the electronic structure such as the control board of the electrical appliance itself, or cause secondary damage to the charger and other structures. The role of discharge, greatly reducing the life of charging components

[0006] 2. Severe wear, increased resistance and energy consumption;

[0007] see figure 2 As shown in the schematic diagram of the action, when the plug structure of the prior art is electrically connected, it is impossible for the user to always insert the aforementioned power socket 20 at an angle close to the vertical center without bias, and it is possible to complete the power supply at various angles. Insertion action, however, the material of the insertion end of the conductive terminal 13 in the prior art is close to the surface hardness of the aforementioned conductive groove 21, coupled with the deviation of the insertion angle mentioned above for the aforementioned conductive terminal 13, the conductive contact of the inner ring of the conductive groove 21 occurs. The wear of the surface will lead to the accelerated oxidation of the conductive contact surface or the reduction of the conductive contact area and the continuous increase of the resistance due to wear, resulting in an increase in power consumption
