Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to Figures 1 to 5, the utility model relates to a USB electrical connector, especially a USB3.0 electrical connector, which includes an insulating body 1 and a shell 2, and the shell 2 wraps the insulating body 1 and is plugged in The end is formed with a socket 21, and the insulating body 1 is provided with a tongue 11 protruding into the socket 21 of the shell 2. The insulating body 1 is combined with a first terminal 3 and a second terminal 4, and the contact part of the first terminal 3 Tear apart into left and right sub-contact parts 31, 32, the two sub-contact parts 31, 32 are located on the upper and lower sides of the tongue 11 and are relatively misaligned; the contact part 41 of the second terminal 4 extends and is located on the upper and lower sides of the tongue 11 The contact portion 41 of the second terminal 4 coordinates with the two sub-contact portions 31, 32 of the first terminal 3 for external electrical plugging to obtain bidirectional plugging performance, and the width of the socket 21 of the housing 2 satisfies the requirements of the first terminal 3 and the first terminal 3. The second terminal 4 coordinates with the working requirements of the two-way insertion, that is, the width of the socket 21 meets the two-way insertion connection of the mating connector. In this embodiment, shrapnels are provided on the left and right sides of the socket 21 of the shell 2 to assist in improving the insertion force. 22. The shrapnel 22 is obtained by punching part of the shell 2, and has an inward pressing force. When the mating connector is inserted, the shrapnel 22 properly presses the mating connector, thereby obtaining sufficient insertion force to achieve the insertion work.

The contact parts of the first terminal 3 and the second terminal 4 of the utility model are distributed on the upper and lower sides of the tongue 11, so whether the external mating connector is inserted from the front or the reverse side, electrical conduction can be realized to achieve signal transmission function, that is to say, the utility model has two-way plug-in performance, which satisfies the two-way plug-in of the plug-in connector, which not only brings convenience to the use, but also makes full use of different points on the terminal contact part to be used alternately, so that the service life of the connector is greatly improved.
