Pressure test switching device, system and method

Abstract

The invention provides a pressure test switching device, system and method. The device comprises a first fixing plate, a second fixing plate, a first USB male connector, a second USB male connector, a USB female connector, a change-over switch, a controller and an outer cover, wherein the outer cover is hollow, the first USB male connector is used for data transmission and charging, and the second USB male connector is used for charging; and the change-over switch is arranged in the shell, the fixed connecting end of the change-over switch is electrically connected with the USB female connector, the controller is arranged in the shell, and the controller controls the movable connecting end to be electrically connected with the first USB male connector or the second USB male connector. According to the invention, the change-over switch is arranged in the shell, so that the first USB male connector, the second USB male connector and the neutral gear can be selectively connected. When data transmission is needed, the first USB male connector can be controlled to be electrically connected; when charging is needed, the movable connecting end can be controlled to be electrically connected with the second USB male connector; when data transmission and charging are not needed, the movable connecting end can be controlled to be idle at the neutral gear, the power failure condition in the pressure testing process is avoided, and the testing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of terminal testing, and in particular to a pressure testing adapter device, system and method. Background technique [0002] Embedded devices with batteries need to do a lot of stress tests in software testing. In order to avoid affecting the test efficiency due to the lack of power of the device during the test, it is necessary to continuously charge the embedded device during data transmission. However, the power consumption of embedded devices is often high, and the charging current requirement exceeds 0.5 amperes. Currently, the charging current in normal use cannot meet this requirement, and there is often a phenomenon of power failure, which affects the test efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a pressure test adapter device, system and method, which can meet the requirements of continuous testing of automated cluster testing, avoi...
