Problems solved by technology
However, because the USB3.0 and eSATA signal pins of the 2-in-1 connector share the same signal pin, when the computer motherboard computer sends out different interface polling signals at the same time, the host computer cannot correctly determine whether the signal interface of the electronic device currently plugged in is USB3. .0 or eSATA signal interface; in order to solve this problem, a solution is proposed

Embodiment Construction
[0022] See first figure 1 As shown, it is a preferred embodiment of the signal conversion device 10 of the present invention, and a schematic diagram of the connection between a USB3.0 and eSATA two-in-one connector 20 and an internal circuit board 30, wherein the internal circuit board follows the The computer device or electronic device used is different. For a desktop computer or a notebook computer, the internal circuit board is the main board. For a computer external box, it is the internal control circuit board of the external box. Wherein the signal conversion device 10 includes:
[0023] A plurality of external communication interfaces 11, 12, including at least Universal Serial Port 3.0 and eSATA, for corresponding connection with the signal pins of the two-in-one connector 20;
[0024] An internal communication interface 14 is connected to the communication bus 31 corresponding to the internal circuit board 30; in the present embodiment, the internal circuit board 3...

The invention relates to a signal conversion device of an all-in-one serial bus connector, comprising a plurality of external communication interfaces, an internal circuit communication interface and a processing unit, wherein the plurality of external communication interfaces are used for connecting corresponding connecting pins of the all-in-one serial bus connector; the processing unit is further electrically connected with the plurality of external communication interfaces and the internal communication interface and is used for periodically detecting all the external communication interfaces until a electronic device is plugged in any external communication interface correspondingly; and then the external communication interface with the plugged corresponding electronic device is subjected to signal two-way conversion with the internal communication interface for an internal circuit board to be communicated with electronic devices with different communication standards.
Description
technical field [0001] The invention relates to a signal converter for an electronic connector, especially a signal conversion device for an all-in-one serial bus (BUS) connector. Background technique [0002] At present, whether it is a desktop computer or a notebook computer, there are many connectors with different communication standards, as a bridge between various electronic devices and computers, such as Universal Serial Port 2.0 (USB2.0), Universal Serial Port 3.0 (USB3.0) or external serial advanced technology configuration (eSATA) connection ports, etc., although their appearance is oblong and rectangular, they still occupy the space of the computer case. Therefore, it has been proposed to connect three groups of similar appearance and size Connectors are integrated into two-in-one or three-in-one connectors to effectively reduce the space occupied by the computer case. [0003] The above-mentioned USB 2.0 connection port includes four signal pins (VBUS, D-, D+ an...
