Problems solved by technology

However, if a hardware switch is added to the electronic device, it will inevitably increase the size of the electronic device
If it is solved by adding software input / output pins, users will need to learn how to operate the software, which will cause inconvenience
In addition, the above two solutions must rely on human operations, and cannot achieve automatic identification
It is worth mentioning that in recent years, U.S. Patent Publication No. US20040248472 and Taiwan Patent Publication No. M359067 have proposed some improved technologies for Universal Serial Bus connectors. Automatic Identity Recognition Technology Based on Bus Connector

[0045] Please refer to image 3 , which shows a USB connector according to an embodiment of the present invention, the body of which is a female type. Such as image 3 As shown, the USB connector 300 has a female-type body 302 . The body 302 has the dimensions of a conventional Type A USB connector. The main body 302 is provided with five pins, which are power pins 304, D - Data transmission pin 306, D + The data transmission pin 308 , the newly added pin 310 and the grounding pin 312 . Wherein, the power supply pin 304 is used to electrically connect the power supply voltage, D - Data transmission pin 306 and D + The data transmission pin 308 is used for transmitting differential data signals, and the ground pin 312 is used for electrically connecting the reference potential. This reference potential is usually ground potential. In addition, the ground pin 312 is separated from the newly added pin 310 by a predetermined distance, so that when a conventional A-type USB...

[0050] Based on the teaching of the first embodiment, those skilled in the art should know that even if the positions of the newly added pin 310 and the ground pin 312 of the USB connector 300 are reversed, as long as the circuits of these two pins are The connection mode is also reversed, and the present invention can also be implemented.

[0051] Next, it will be described how the above-mentioned USB connector 300 is connected to a traditional A-type USB connector whose main body is a female seat type. It will also be explained that in this case, the two USB connectors How will the two electronic devices belong to identify each other.

[0053] In this embodiment, the USB connector 300 is connected to a conventional A-type USB connector with a female body through a converter. This converter has two USB connectors, one of which is a conventional Type-A USB connector with a male body, as in figure 2 A conventional Type A Universal Serial Bus connector 200 is shown. And the other USB connector of this converter is to adopt a kind of USB connector, as Figure 5 Universal Serial Bus connector 500 is shown.

[0054] Such as Figure 5 As shown, the USB connector 500 has a body 502 in the form of a male socket. This body 502 has the dimensions of a conventional Type A Universal Serial Bus connector. The main body 502 is provided with five pins, which are power pins 504, D - Data transmission pin 506, D + The data transmission pin 508 , the newly added pin 510 and the grounding pin 512 . Wherein, the configuration positions of the five pins in the body 502 are corresponding to the configuration positions of the...

Abstract

The invention relates to a universal serial bus connector and a converter for the universal serial bus connector. The universal serial bus connector comprises a body, a first pin, a second pin, a third pin, a fourth pin and a fifth pin, wherein the body has the size of an A-type universal serial bus connector; the five pins are all arranged in the body; the first pin is used for electrically connecting power voltage; the second and third pins are used for transmitting differential data signals; the fifth pin is used for electrically connecting reference potential; the fifth pin is at a preset distance away from the fourth pin; and when the universal serial bus connector is connected with another A-type universal serial bus connector, the fourth pin is electrically connected with the fifth pin by a grounding pin of the four pins of the A-type universal serial bus connector. In addition, the invention also provides the converter applied to the universal serial bus connector.

Description

technical field [0001] The present invention relates to a connector and its converter, and in particular to a Universal Serial Bus (Universal Serial Bus, USB) connector and its converter. Background technique [0002] Among various existing USB connectors, the mini USB connector has been widely used in high-end portable electronic devices. Among the five pins of the mini USB connector, one pin is an Identity (ID) identification pin. When a Mini Universal Serial Bus connector is connected to an electronic device, the electronic device to which the Mini Universal Serial Bus connector belongs can use the voltage level of the identification pin to automatically identify that it is compatible with the Mini Universal Serial Bus connector. The identity of the electronic device connected to the bus connector. [0003] When the voltage level of the identification pin shows a high potential (High), the electronic device to which the mini USB connector belongs will recognize that the...
