Abstract

The invention relates to a universal serial bus interface conversion device. The universal serial bus interface conversion device comprises a first interface connector, a second interface connector, athird interface connecting port and a detection module. According to the invention, the first interface connector and the second interface connector can be plugged at the same time to obtain relatively large power supply, so that the problem of insufficient power supply is solved. Moreover, the connection states of the first interface connector and the second interface connector can be detected by the detection module, and a single default function or a plurality of default functions are determined to be started according to a detection result.

Description

technical field [0001] The invention relates to a conversion device, in particular to a conversion device for converting a universal serial bus C-type plug into a universal serial bus A-type plug. Background technique [0002] As the functions of various electronic products are becoming more and more powerful, and handheld devices are becoming more and more popular, the demand for signal transmission between various products or devices is also increasing; In the outline of the housing, it is a common goal of the industry to set more terminal interfaces (for example, connectors or complementary connectors) that can perform signal transmission with different devices. Wherein, the connector is an electrical plug (Electrical plug), and the complementary connector is an electrical receptacle (Electrical receptacle), also called a port. [0003] Currently, connectors with Universal Serial Bus (USB) interfaces are the mainstream in the market. The connector specifications of the ...
