The high-frequency terminal 81 and the insulating member 82 are molded to form the high-frequency terminal module 80, and the high-frequency terminal module 80 is inserted into the corresponding terminal slot from back to front. In this way, through the setting of the high-frequency terminal group, the high-frequency and high-speed passing performance can be better, and the high-frequency terminal 81 is molded to form the insulating member 82 to form the high-frequency terminal module 80, and the high-frequency terminal module 80 is inserted into the corresponding terminal slot from back to front, so that the modular design and plug-in design of the high-frequency terminal 81 are realized, so that the high-frequency terminal 81 integrates molding and plug-in, thereby simplifying the assembly process of the high-frequency terminal 81, making the high-frequency terminal assembly simple, more conducive to molding and manufacturing, and improving the production and processing efficiency, and the insulating member 82 alone covers the high-frequency terminal 81 to reduce the influence of impedance, and the insulating member 82 can separate the high-frequency terminal 81 from other terminals, thereby reducing the interference of other terminals on the high-frequency terminal 81.

[0058] The high-frequency terminal 81 has a bent first contact portion 811 at one end and a bent first welding portion 812 at the other end; the insulating member 82 is molded and covered on the middle part of the high-frequency terminal 81, the first contact portion 811 is exposed in the insertion cavity 11, and the first welding portion 812 is exposed outside the rear end of the insulating body 10.

[0059] The insulating member 82 has a through slot 821 on one side facing the insulating body 10 , and the middle portion of the high-frequency terminal 81 is exposed in the through slot 821 , so that the high-frequency terminal 81 can be cooled through the through slot 821 to avoid the problem of overheating.

[0060] The grounding terminal 30 is provided with two, and the insulating body 10 is provided with two first terminal grooves 12 arranged with symmetrical spacing, and the grounding terminal 30 is inserted into the first terminal groove 12 from back to front; the power terminal 40 is provided with two, and the insulating body 10 is provided with two second terminal grooves 13 arranged with symmetrical spacing, and the two second terminal grooves 13 are located between the two first terminal grooves 12, and the power terminal 40 is inserted into the second terminal groove 13 from back to front; the insulating body 10 is provided with a plurality of third terminal grooves 14, and the plurality of third terminal grooves 14 are located between the two second terminal grooves 13, and the signal terminal 50 is inserted into the second terminal groove 13 from back to front.

The insulating part alone covers the high-frequency terminal to reduce the influence of impedance, and the insulating part can separate the high-frequency terminal from other terminals, thereby reducing the interference of other terminals on the high-frequency terminal; and, by making the width of the signal terminal the same at all places, the overall width of the signal terminal is uniform, which can adapt to high-frequency signal transmission, and a current increasing part is set on the signal terminal, which is equivalent to increasing the resistance value of the signal terminal, thereby improving the ability of the connector to transmit large currents, effectively solving the problem of excessive temperature when the connector transmits large currents, and a card point is set on the signal terminal, which can make the connection between the signal terminal and the insulating body more stable.
