Charging communication interface with anti-static and fool-proof structure

Abstract

The invention discloses a charging communication interface with an anti-static and fool-proof structure. The charging communication interface comprises an interface socket and an interface plug, wherein the interface socket comprises a socket insulator and an annular socket magnet surrounding the socket insulator; the interface plug comprises a plug insulator and an annular plug magnet surrounding the plug insulator; according to the magnetism characteristic of same poles repelling to each other and opposite poles attracting to each other, S pole and N pole positions of the annular socket magnet on the horizontal end face are corresponding to the N pole and S pole attracting positions of the annular plug magnet, as the necessary condition for correct connection. The interface plug and the interface socket according to the invention both adopt magnets; when the directions are correct, the magnets are easily attracted; when the directions are opposite, the magnets repel to each other; the condition of reverse plugging or staggered plugging can be effectively prevented; the invention provides a double-suction type fool-proof anti-touch interface with simple technique and lower cost.

Description

technical field [0001] The invention relates to a communication interface, in particular to a charging communication interface with an anti-static and fool-proof structure. Through the design of the magnetic fool-proof structure, the plug and socket are easy to plug in and have reliable contact, and are not easy to be reversed, and will not be exposed. Prevent static electricity and electric ground short circuit. Background technique [0002] Nowadays, more and more portable devices have charging design, usually the interface design of USB connector. In general, (1) the interface without magnet needs to be manually aligned with the interface and identify the front and back, with a strong sense of direction, such as in Plugging and unplugging at the wrong position or angle can easily damage the interface; insert the plug into the socket with force, and the life of the USB socket will be limited after repeated plugging and unplugging. (2) As for the interface with magnets, un...
