Abstract

The invention discloses a chip controlled USB switcher. The chip controlled USB switcher comprises a USB male end, a USB female end and a switching circuit, wherein the USB male end is matched and connected with a USB interface in a computer table, and comprises four USB3.0 signal pins and two USB2.0 signal pins; the USB female end is matched and connected with a USB interface of USB3.0 equipment, and comprises four USB3.0 signal pins and two USB2.0 signal pins; the USB female end and the USB male end are connected with each other through a power supply positive pin and a grounding pin in a butt joint manner; the switching circuit comprises a selection chip; one end of the selecting chip comprises a selection end, a first selected end, a second selected end and a trigger end; and pins of the selection end correspond to pins of the first selected end and of the second selected end. According to the chip controlled USB switcher, the test equipment is decreased, part of the insertion and extraction damages and the troubles in the operation are avoided, and the labor hour is reduced.

Description

【Technical field】 [0001] The invention relates to a switcher, in particular to a chip-controlled USB switcher. 【Background technique】 [0002] For electronic products such as notebook computers, there are usually several USB (Universal Serial Bus, 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...
