Description

Portable data transmission device

Technical field

The present invention relates to an electronic mobile data transmission device, and more particularly to a portable data transmission device having a double-sided USB plug.

Background technique

Currently, mobile storage devices such as USB flash drives and card readers on the market are independent products, because a USB plug can only pass one USB information, so that when

When we need both USB flash drives and card readers, we need to equip two USB products, which causes inconvenience to people and wastes social resources.

At present, mobile electronic devices such as mobile phones, PDAs, and digital cameras on the market are equipped with chargers at random, which are bulky and are not suitable for carrying.

In addition, existing mobile devices usually need to be connected to a computer for data transmission or charging, but these randomly configured USB data lines are generally 60-150.

Centimeters are even longer, and these randomly configured data cables connect the plugs of computers and mobile devices to the outside, lack protection, and are not portable

Belts, in today's society where people appreciate the increasing level, the appearance is also lack of beauty.

With the popularization and application of computers in today's society, people can use computers on business trips or in office, as well as in general public places such as Internet cafes and banks.

On the USB ports of these computers, charging power and data transmission can be provided. These public places do not provide data lines and the interfaces of mobile devices are

It will not be unified, and it is not convenient for users to transmit and charge data to their mobile devices. In this case, a portable product suitable for mobile device users is needed.

Products to solve the current deficiencies, practical and convenient, short and portable, beautiful and pleasing to the eye is the current demand for such products.

Chinese patent document CN1767271, which discloses a USB connector plug, which cooperates with a standard USB interface socket, and is inserted on the socket tongue

a metal terminal contacting the electrical contact and a connector body carrying the metal terminal, the metal terminal being two sets of gold capable of independently performing standard USB signal transmission

The terminals are located on opposite sides of the connector body. The connector body is further provided with an isolating machine for preventing electrical contact between the metal terminal and the outer metal shell of the socket.

Structure. The invention is provided on the opposite side of the plug body with a metal terminal matched with an electrical terminal on a standard USB socket, whichever is on the top
