otg multi-purpose fast charging cable

Abstract

An OTG multipurpose fast charging wire disclosed by the present invention comprises a first plug fixed on a first socket, a second plug fixed on a second socket, a fast charging and data controller and a changeover plug. The first plug is formed by combining a USB A-type plug and an OTG plug which are connected mutually, and the second plug is set as a Micro USB plug. The first and second plugs are connected with a control circuit of the fast charging and data controller separately and electrically via connection lines, at least one side surface part of the first socket and / or the second socket is equipped with a plugging groove, and the changeover plug is connected with the first socket or the second socket detachably via a plugging block plugged in the plugging groove. The OTG multipurpose fast charging wire possesses the fast charging, data protection and OTG functions, can realize the switching of a fast charging mode and a data transmission mode, can realize the situation that the changeover plug is disassembled to be in butt joint with the first plug or the second plug to thereby be compatible with various plug interfaces, and is convenient to use and carry.

Description

technical field [0001] The invention relates to the technical field of electronic data transmission, and more specifically, relates to an OTG multi-purpose fast charging line. Background technique [0002] With the popularity of electronic digital devices such as smartphones, USB data cables are widely used in various industries and products. Now the most common common interface for Android electronic devices is the Micro USB interface. Since Apple’s mobile phone came out and promoted its own unique Since the data transmission structure standard, along with the popularization of Apple electronic devices, the Lightning interface has also become one of the standard interfaces. With the development of various application software, consumers have higher and higher demands on the capacity of mobile devices, so OTG technology, which can expand in real time, has become another favorite of mobile devices after SD cards. Accompanied by the increase in various applications, consumers...

AI Technical Summary

Problems solved by technology

Accompanied by the increase in various applications, consumers use mobile devices more frequently and for longer periods of time, resulting in limited power that cannot meet demand, and the speed of ordinary charging methods is too slow, which affects the experience of using mobile devices. Fast charging technology also emerges at the historic moment

[0003] Existing USB data cables are often only equipped with a single data interface, but now many people have electronic digital devices such as Android and Apple mobile phones or tablet computers, so they have to be equipped with multiple data cables of different specifications, such as MicroUSB data cable, Lightning data cable, OTG data cable, fast charging cable, etc., which can be replaced at any time. The quantity is so large that it is very inconvenient to use and carry
