Description

Reversibly-insertable USB plug

The invention name of the specification: USB plug technical field capable of being oppositely plugged in forward and reverse directions

[0001] The invention relates to the technical field of electric connectors, in particular to a USB plug capable of being oppositely plugged in the positive and negative directions.

Background

[0002] USB (Universal Serial BUS), which is an external BUS standard for standardizing the connection and communication between a computer and external devices, is an interface technology applied in the field of PCs. The USB interface supports plug and play and hot plug functions of the device. Among the peripheral interfaces for data transmission and data exchange, the Universal Serial Bus (USB) interface is undoubtedly one of the most widely used interfaces in the fields of computers and peripheral electronic consumer products. Peripheral peripherals of computers are mostly connected with computers through USB (universal serial bus) for data transmission and exchange, such as mice, keyboards, USB (universal serial bus) disks, printers, mobile phones, cameras and the like. It is necessary to install the US B socket on the computer and the plug on the peripheral external device of the computer, and the plug is inserted into the socket during connection to make the two electrically connected. At present, a MICRO universal serial bus (MICRO USB) interface connector is widely used in connector interfaces of portable mobile devices such as mobile phones and tablet computers for transmission communication and charging

[0003] Because the electrical connection points of the plug and the socket are designed to be in one-to-one correspondence, the wrong insertion can cause great dangers of invalidation, even equipment burnout and the like. In order to prevent people from inserting wrong plugs when the USB interfaces are used for butt joint, the USB interfaces are specially designed to be fool-proof, namely plugs and sockets can be inserted only in an alignment direction due to the characteristic of single-side plug-in, and therefore much time for examination and checking is wasted. Thus, when the plug is used, a user often needs to check which direction the socket is, adjust the plug to the same direction and insert the plug, or change the plug not to another direction, and sometimes the plug or the socket is damaged due to hard insertion and hard force.
