USB bidirectional-conduction male-head connector

The utility model relates to a USB bidirectional-conduction male-head connector and belongs to the technical filed of electronics. The USB bidirectional-conduction male-head connector comprises a shielding housing which accommodates at least a first insulating colloid and a second insulating colloid. The first insulating colloid is combined with a grounding transmission conductor, a first signal transmission conductor, a second signal transmission conductor, a power source transmission conductor, a first differential signal transmission conductor, a second differential signal transmission conductor, a third differential signal transmission conductor, a fourth differential signal transmission conductor, and a fourth grounding transmission conductor. The second insulating colloid is combined with a first grounding transmission conductor, the third signal transmission conductor, the fourth signal transmission conductor, a first power source transmission conductor, and a fifth differential signal transmission conductor, a sixth differential signal transmission conductor, a seventh differential signal transmission conductor, an eighth differential signal transmission conductor, and a fifth grounding transmission conductor. One end of the grounding transmission conductor and one end of the first grounding transmission conductor are provided with a grounding contact portion and a first grounding contact portion respectively. The grounding contact portion and the first grounding contact portion are split towards the other end of the grounding transmission conductor and the other end of the first grounding transmission conductor respectively, and extend to form a first grounding extending portion and a second grounding extending portion as well as a fourth grounding extending portion and a fifth grounding extending portion respectively. Through the setting of extending portions of the grounding transmission conductor and the mutual connection of the extending portions, the problem of crosstalk interference generated by a high-frequency signal connector can be effectively solved.
