[0003] However, since it takes a certain amount of time to restart the terminal product after it is powered off, when the terminal product needs to go through multiple tests, it needs to go through the steps of power-off and restart in the process of performing each test, resulting in the failure of the terminal product. The test time is too long, which seriously reduces the test efficiency

The invention provides a dual-AC test pre-power on device comprising a cabinet, a power adapter, a first power plug and a second power plug. The power adapter comprises a first power interface, a second power interface and a socket, and is arranged in the cabinet. The first power interface is electrically connected with the first power plug through a first cable. The second power interface is electrically connected with the second power plug through a second cable. The first power interface and the second power interface are electrically connected with the socket. The socket is used for being connected with a product to be tested. The first power plug is used to be plugged into a backup power supply. The second power plug is used to be plugged into a test station power supply. The dual-AC test pre-power on device can power on the product to be tested before the product to be tested enters the test station to be tested and does not interrupt the power supplied to the product to be tested before the product to be tested moves to a next test station to prevent the product to be tested from being frequently powered down and restarted, and can effectively improve the test efficiency.
Description
technical field [0001] The embodiments of the present invention belong to the technical field of testing, and in particular relate to a dual-AC testing pre-power-on device. Background technique [0002] With the continuous development of science and technology, various terminal products emerge in an endless stream, bringing great convenience to people's life and entertainment. The terminal product needs to go through a number of tests in the production process, and only after its various performances are tested and passed, can it finally become a qualified finished product. When the terminal product moves from one test station to the next test station for testing, it needs to disconnect the power connection with the current test station, and then power on the test again when it arrives at the next test station. [0003] However, since it takes a certain amount of time to restart the terminal product after it is powered off, when the terminal product needs to go through mult...
