Abstract

The invention relates to a universal serial bus interface conversion device, which includes a first interface connector, a second interface connector, a third interface connection port and a detection module. The present invention can obtain larger power supply by simultaneously inserting the first interface connector and the second interface connector, so as to solve the problem of insufficient power supply. Furthermore, the detection module can be used to detect the connection status of the first interface connector and the second interface connector, and a single default function or multiple default functions can be activated according to the detection result.

Description

Universal Serial Bus Interface Conversion Device technical field The present invention relates to a kind of conversion device, relate in particular to the conversion of universal serial bus C form plug into universal serial bus Conversion device for line A form plugs. Background technique [0002] Since the functions of various electronic products are becoming more and more powerful, and hand-held devices are also becoming more and more popular, various products The demand for signal transmission between products or devices is also increasing; based on this, how to use the casing of products or devices with ever-shrinking volumes In the surrounding contour, there are more terminal interfaces (for example, connectors or docking interfaces) that can transmit signals with different devices. Complementary connectors), which has become the goal of the industry's joint efforts. Among them, the connector is an electrical connection plug (Electrical plug), and the complemen...
