Abstract

The present invention discloses a USB2.0 and USB3.0 switcher, including: a USB male head, which is connected with a USB interface on a computer machine, and the USB male head has a first signal pin group and a second signal pin Group and power pin group; USB female head, is connected with the USB interface of USB3.0 equipment, and described USB female head has first signal pin group and second signal pin group and power supply pin group, described USB The power supply pin group of the female head is docked with the power supply pin group of the USB male head; the switching circuit has a slider on it, and the slider slides to select the first signal pin group of the USB male head. The first signal pin group of the USB female connector is connected, or the second signal pin group of the USB male connector is connected with the second signal pin group of the USB female connector. The test equipment is reduced; partial plugging damage and operational troubles are avoided, and man-hours are saved.

Description

【Technical field】 [0001] The invention relates to a switcher, in particular to a USB2.0, USB3.0 switcher. 【Background technique】 [0002] For electronic products such as notebook computers, there are usually several USB (UniversalSerialBus, universal serial bus) interfaces on it. The current USB interfaces on electronic products are usually USB3.0 interfaces. Before the electronic products leave the factory, tests will be carried out to ensure that the functions of each interface are qualified. For the USB3.0 interface, in order to be backward compatible, it is necessary not only to test whether it can work normally when connected to USB3.0 devices, but also to test whether the devices connected to USB2.0 can work normally. USB2.0 devices will use a set of send (transport) and receive (receive) pins, while USB3.0 devices will use two sets of send and receive pins. [0003] The current test method is to use USB2.0 equipment (such as U disk), USB3.0 equipment (such as U disk...
