A protrusion extends from the current-carrying end 51 towards the signal end 61. The signal end 61 is provided with an avoidance groove adapted to the protrusion. The cross-sectional area of the current-carrying end 51 is larger than that of the signal end 61. The end of the current-carrying end 51 and the second contact end 62 are respectively used to be correspondingly connected to the male terminal pins 21. One side of the housing assembly is recessed inward to form a stop portion 2, and a vertical stop surface 7 is formed at the end of the stop portion 2.

[0032] In the large-current Type-C connector of the present utility model, through the cooperation of the provided protrusion and the avoidance groove, the cross-sectional area of the current passing through the power terminal 5 is increased, enabling it to better meet the transmission requirements of high power, improving the current-carrying capacity of each power terminal 5. The cross-sectional area of the end of the current-carrying end 51 of the power terminal 5 is relatively large, which can better meet the temperature rise test, increase the contact conduction area between the power terminal 5 and the pins of the male connector 20, reduce the heat generation phenomenon. At the same time, the cross-sectional area of the current-carrying end 51 itself is also relatively large, reducing the heat generated by the power supply within the limiting component 3 and the insulating body 12, thus better meeting the temperature rise test.
