Description
[technical field]
The present invention relates to switch, particularly relate to a kind of USB2.0, USB3.0 switch。
[background technology]
For electronic products such as notebook computers, it would generally have several USB (UniversalSerialBus, USB (universal serial bus)) interface。The current USB interface being located on electronic product is generally all USB3.0 interface, and before electronic product dispatches from the factory, the function that can carry out testing to guarantee each interface is qualified。For the interface of USB3.0, in order to backward compatible, not only need to test its connect USB3.0 equipment whether can normal operation, in addition it is also necessary to can test connects the equipment of USB2.0 normal operation。USB2.0 equipment can use one group of transmission (transport), receive (receive) pin, and USB3.0 equipment can use two groups of transmissions, receive pin。
Current test mode be adopt the equipment (such as USB flash disk) of USB2.0, the USB interface of described electronic product is carried out USB2.0, USB3.0 functional test by the equipment (such as USB flash disk) of USB3.0 respectively, therefore need to use different USB devices when test, and need to perform twice at plug。
Visible, adopt above-mentioned test mode, often, test process bothers, expends man-hour and easily cause plug damage in plug；Simultaneously, it is necessary to use two class USB flash disks, cause unnecessary waste。
In view of this, it is necessary in fact to develop a kind of USB2.0, USB3.0 switch, to solve the problems referred to above。
[summary of the invention]
Therefore, it is an object of the invention to provide a kind of USB2.0, USB3.0 switch, solve backward compatible USB3.0 equipment is switched over, to reach its function being operated under USB2.0 and USB3.0 state respectively。
In order to achieve the above object, USB2.0, USB3.0 switch provided by the invention, including:
USB male joint, is connected with the USB interface on computer board, and described USB male joint has power pins group and the first signal pins group of optional use, secondary signal pin set；
USB female, it is connected with the USB interface of USB3.0 equipment, described USB female has power pins group and the first signal pins group of optional use, secondary signal pin set, and the power pins group of described USB female is docked with the power pins group of described USB male joint；
Switching circuit, it has slide block, described skid, select each pin by the first signal pins group of described USB male joint with the first signal pins group of described USB female to connect one to one, or each pin of the secondary signal pin set of described USB male joint Yu the secondary signal pin set of described USB female is connected one to one。
Optionally, described first signal pins group includes two pins of USB2.0, respectively receives, sends pin。
Optionally, described secondary signal pin set includes two pairs of pins of USB3.0, and every pair of pin includes two pins, respectively receives, sends pin。
Compared to prior art, utilize USB2.0, USB3.0 switch of the present invention, by the slip of slide block is selected, can switch and reach computer board and described USB3.0 equipment and carry out connecting or the connection of USB3.0 signal pins of USB2.0 signal pins, thus reaching described USB3.0 equipment to be respectively operated in the function under USB2.0 or USB3.0 state。Visible, use a USB3.0 equipment can reach the test to two kinds of functions of computer board, decrease test equipment；Simultaneously, it is to avoid what adopt two kinds of USB devices repeatedly plugs the plug damage caused and operational trouble, saves man-hour。
