The connector of USB TYPE C is an elliptical jack, which is installed in the mobile electronic device and can be charged without distinguishing the front and back sides, which has excellent convenience. Furthermore, the maximum output voltage of the USB TYPE C interface is 20 volts (V); The maximum output current is 5 amps (A), and its output power is higher and smaller than the traditional USB TYPE A interface. However, due to its small size, the conductive terminals (especially power terminals and ground terminals) in the connector can be laid out in a very narrow space, resulting in the output current far from reaching the rated specifications.

Furthermore, because the wiring design of the conventional USB TYPE C connector is limited by its small space, and the plurality of conductive terminals provided in the insulating body inside the connector are also miniaturized, plus these conductive terminals are used to The terminal fixing portion fixed to the terminal groove of the insulating body mostly forms a fixing structure with a bent shape. The bent fixing portion causes high impedance during the transmission of electronic signals and is not conducive to the passage of current. The output current cannot reach the predetermined specifications, so those engaged in this industry must use all their means to overcome this problem, and this creation is a kind of electrical connector structure to solve this problem.

Therefore, in view of the above problems and deficiencies, the creators collected relevant materials, evaluated and considered through multiple parties, and based on the years of experience accumulated in this industry, through continuous trial and modification, began to have such electrical connectors with reduced impedance New patent for terminal structure was born.

The main purpose of this creation is to provide an electrical connector terminal structure with reduced impedance, which is used in a connector of USB TYPE C interface. The connector has an insulating body and a plug-in space in the insulating body. A plurality of terminal grooves are provided in the terminal grooves, and a plurality of conductive terminals are provided in the terminal grooves. The conductive terminals are located at one end of the insertion space of the insulating body and have a mating portion. The mating portion extends toward the other end of the conductive terminal. To be fixed to a fixing portion of the terminal slot, and the fixing portion continues to extend a welding portion for welding and fixing a cable or a circuit board, and the conductive terminal fixing portion is chiseled with at least one resistance reduction hole, In order to form the terminal structure of the electrical connector with reduced impedance, at the same time, the noise interference between the multiple terminals can be reduced.

The secondary purpose of this creation is that the width of the fixing portion of the conductive terminals is larger than the butting portion and the soldering portion.

Another purpose of this creation is that the shape of the drag reduction hole is an oblong shape.
