Abstract

The invention provides a cable, which comprises a first plug, a second plug and an automatic switch module, wherein the first plug comprises a first voltage bus (VBUS) pin, a first D+ pin, a first D- pin, a first ground (GND) pin and a first ID pin; the second plug comprises a second VBUS pin, a second D+ pin, a second D- pin, a second GND pin and a second ID pin; the second VBUS pin, the second D+ pin, the second D- pin and the second GND pin are connected with the first VBUS pin, the first D+ pin, the first D- pin and the first GND pin respectively; and the automatic switch module is connected with the first ID pin and the second ID pin and automatically controls the first ID pin or the second ID pin to be grounded. Due to the automatic switch module arranged between the first plug and the second plug, the first ID pin or the second ID pin is automatically controlled to be grounded, and is prevented from being repeatedly inserted / extracted by a user during connection.

Description

【Technical field】 [0001] The invention relates to a cable, in particular to a cable that prevents users from repeatedly plugging and pulling out when connecting. 【Background technique】 [0002] USB OTG is the abbreviation of USB On-The-Go. It is a technology developed in recent years. It was announced by USB Implementers Forum on December 18, 2001. It is mainly used in the connection between various devices or mobile devices for data exchange. Especially PDAs, mobile phones, consumer devices. Change the inconvenience of data exchange between multiple connectors of different standards among devices such as digital cameras, video cameras, printers, and memory cards of up to 7 standards. The development of USB technology enables PCs and peripheral devices to connect various devices together in a simple way and with moderate manufacturing costs. The above-mentioned applications can be used as the peripherals of the PC through the USB bus and under the control of the PC. data e...
