Description

M250390 IV. Creation Instructions (l) ---- [Technical Field to which the New Type belongs] This creation is about a thin US Β plug connection with a common ground = 'specially refers to the US after the thinned design Β ( The A-Type) plug connection has a system common ground and conforms to the original USB specifications. [Previous technology] Universal Serial Bus (USB) is a very common connection interface for computers. USB is an external bus that supports plug and play installation. With U S B, users do not need to shut down or restart the computer to connect and disconnect the computer and the device. A single USB port can be used to connect up to 127 peripheral devices, including speakers, phones, CD-ROM drives, joysticks, tape drives, keyboards, scanners, cameras, and more. The USB port is usually located near the serial or parallel port on the back of the computer. Please refer to the first figure, which is a perspective view of the commonly-used U S B (A-Type) socket (female) and plug (male) in the current market. The current universal USB (A-Type) sockets 70 and plugs 90 comply with the physical size and location of the USB (A-Type) sockets and plugs to achieve the purpose of electrical connection.

Circuit board 80. The USB socket 70 has an outer frame 7 2 which is stamped and formed from a metal plate and is grounded to the computer system chassis, and a tongue 7 6 is provided inside the outer frame 7 2. The four side walls of the outer frame 72 are all integrally recessed inwardly with the elastic pieces 7 4. The tongue piece 76 is an electrical connection board, and the bottom surface of the tongue piece 76 is provided with four conductive spring pieces 78. M250390 4. Creation instructions (2) The USB plug 90 is usually installed on the user side. The USB plug 90 has an outer frame 92, which is stamped and formed from a metal plate, and a tongue 96 is disposed inside the outer frame 92. The outer frame 9 2 meets the electrical specifications of the USB-IF common ground through the USB socket 70 being grounded to the computer system chassis. Two square holes 9 4 are formed on the upper and lower sides of the outer frame to facilitate connection with the outer frame of the USB socket 70. The elastic piece 74 of 72 contacts and has a fastening function. The middle tongue piece 96 is an electrical characteristic conduction fitting board. Four conductive spring pieces 9 8 are arranged above the tongue piece 96, which are mated with the tongue piece 7 2 of the USB socket 7 to conduct to the user. end. The prior art U S B socket 70 and plug 90 are fitted with a certain directivity, but they cannot be fitted in the opposite direction. However, the peripheral sizes of the u S B socket 70 and the plug 90 in the prior art are limited by the outer frame, and they are often pushed against the plugs on the parallel U S B socket when using the plug, which has inconvenience in use. The key is that the frame becomes a major obstacle to thin design. Therefore, it can be seen from the above that the above-mentioned conventional USB plug connector has obvious inconveniences and defects in practical use, and needs to be improved. The reason is that the author feels that the above-mentioned shortcomings can be improved. He has devoted himself to research and cooperated with the application of theories to finally propose a rational design and effectively improve the above-mentioned original creations. [New content]
