Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Embodiment: As shown in Figures 1 to 4, a USB bidirectional interface includes an interface body 1, and one end of the interface body 1 is connected with a metal connection shell 2, and a signal connection piece 4 is arranged inside the metal connection shell 2, and the signal The connection piece 4 is located in the middle of the metal connection shell 2, one end of the signal connection piece 4 is connected to the interface body 1, the two sides of the signal connection piece 4 are signal connection surfaces 41, and the signal connection surface 41 is provided with conductive terminal groups.

When the utility model is connected with the female base 6, as shown in Figure 3, the USB bidirectional interface is inserted into the interface of the female base 6, and a signal connection surface 41 of the signal connection piece 4 is opposite to the anti-fooling board 61, and the signal connection piece 4 When continuously inserted into the interface of the female base 6, the conductive terminal 3 of the conductive terminal group on the signal connection surface 41 abuts against the signal connection terminal 62 on the anti-dumb board 61, and conducts; thereby realizing the connection between the USB bidirectional interface and the female base 6 connect. During the plugging process, there is no need to consider the direction of the USB bidirectional interface, which is convenient to use.

In order to facilitate the design and installation of the conductive terminal 3, the conductive terminal 3 of the conductive terminal group is a conductive metal sheet, and the conductive metal sheet is fixed on the signal connection surface 41. During specific operations, the embedded method is adopted, and one end of the conductive metal sheet passes through the signal.
