Description
[technical field]
The utility model relates to switch, particularly relates to a kind of USB2.0, USB3.0 switch.
[background technology]
For electronic products such as notebook computers, it can have usually several USB (Universal SerialBus, USB) interface.The current USB interface be located on electronic product is all USB3.0 interface usually, before electronic product dispatches from the factory, can carry out testing to guarantee that the function of each interface is qualified.Whether for the interface of USB3.0, in order to backward compatible, not only need to test it and connect USB3.0 equipment and can normally work, can also need to test the equipment connecting USB2.0 normally work.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 adopts the equipment (being such as USB flash disk) of the equipment of USB2.0 (being such as USB flash disk), USB3.0 to carry out USB2.0, USB3.0 functional test to the USB interface of described electronic product respectively, therefore need to use different USB device when testing, and need to carry out twice plug.
Visible, adopt above-mentioned test mode, plug often, test process bothers, expend man-hour and easily cause plug to damage; Meanwhile, need use two class USB flash disk, cause unnecessary waste.
In view of this, be necessary to develop a kind of USB2.0, USB3.0 switch, to solve the problem in fact.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of USB2.0, USB3.0 switch, solves and switches backward compatible USB3.0 equipment, is operated in function under USB2.0 and USB3.0 state respectively to reach it.
In order to achieve the above object, USB2.0, USB3.0 switch that the utility model provides, comprising:
USB male joint, is connected with the USB interface on computer board, and described USB male joint has power pins group and can the first signal pins group, the secondary signal pin set of choice for use;
USB female, be connected with the USB interface of USB3.0 equipment, described USB female has power pins group and can the first signal pins group, the secondary signal pin set of choice for use, and the power pins group of described USB female is docked with the power pins group of described USB male joint;
Commutation circuit, it has slide block, described skid, select each pin of the first signal pins group of described USB male joint and the first signal pins group of described USB female to connect one to one, or each pin of the secondary signal pin set of the secondary signal pin set of described USB male joint and described USB female is connected one to one.
Optionally, described first signal pins group comprises two pins of USB2.0, is respectively reception, sends pin.
Optionally, described secondary signal pin set comprises two pairs of pins of USB3.0, and often pair of pin comprises two pins, is respectively reception, sends pin.
Compared to prior art, utilize USB2.0, USB3.0 switch of the present utility model, by selecting the slip of slide block, can switch and reach computer board and described USB3.0 equipment carries out the connection of USB2.0 signal pins or the connection of USB3.0 signal pins, thus reach respectively described USB3.0 equipment be operated in USB2.0 or USB3.0 state under function.Visible, use a USB3.0 equipment can reach test to computer board two kinds of functions, decrease test equipment; Meanwhile, what avoid employing two kinds of USB device repeatedly plugs the plug damage caused, and operational trouble, saves man-hour.
