When the tongue plate 60 is inserted into the USB slot, the metal contacts (VDD, D-, D+, GND) set on the tongue plate 60 of the USB device must be aligned with the metal contacts (VDD, D+, GND) provided on the tongue plate 71 in the insertion slot. -, D+, GND), but because the orientation of the USB slots in various electronic devices is not the same, the diagram is an example where the metal contacts (VDD, D-, D+, GND) face up, and it may also face Therefore, when inserting a USB device, the user must first check whether the metal contact of the tongue of the USB slot is facing upwards or downwards, and turn over so that the metal contact of the tongue 60 of the USB device is aligned with the metal contact of the tongue 71 of the socket. It can only be inserted, which is inconvenient to use and needs to be improved.

Utility model content

In view of the technical defect that the above-mentioned single-mating surface USB device requires the user to cooperate with the setting of the metal contact on the tongue plate of the insertion groove, which causes inconvenience in use, the main purpose of this utility model is to propose a USB device with double-mating surfaces. device.

The main technical means used to achieve the above-mentioned purpose is to make the USB device with two plugging surfaces include:

A device body, which is provided with a USB signal processing chip and a tongue plate, the USB signal processing chip at least includes a high potential terminal, a data negative terminal, a data positive terminal and a ground potential terminal, the tongue plate has a the upper surface and the lower surface;

Two sets of metal contacts, which are respectively arranged on the upper and lower surfaces of the tongue plate of the device body, each set of metal contacts includes a high potential pin, a data negative pin, a data positive pin and a ground potential pin , and are respectively electrically connected to the corresponding terminals of the signal processing chip, and the high potential pin on the upper surface is aligned with the ground potential pin on the lower surface; the data negative terminal pin on the upper surface is aligned with the data positive terminal pin on the lower surface ; The material positive end pin on the upper surface is aligned with the material negative end pin on the lower surface; the ground potential pin on the upper surface is aligned with the high potential pin on the lower surface.

Because the order of the USB contacts is fixed, the utility model makes the arrangement order of the metal contacts on the tongue plate and the lower surface opposite, so that turning over the USB device will not cause the arrangement order of the metal contacts to change, and the tongue plate is on the upper and lower surfaces. A group of metal contacts of the same specification for the electrical connection of the USB signal processing chip are formed. The metal contacts on the upper surface of the tongue plate can be used to align with the slots where the metal contacts face downward, while the metal contacts on the lower surface of the tongue plate can be used to align with the metal contacts. The slot faces downward, so the user does not need to deliberately match the direction of the USB slot insertion surface, which is convenient to use.
