[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-direct current pre-powering device for tests. The device comprises a box, a power adapter, a first power plug, a second power plug, a first AC-DC converter and a second AC-DC converter, wherein the power adapter comprises a first power interface, a second power interface and a socket, and is arranged in the box; the first AC-DC converter is connected between the first power interface and the first power plug via a first cable, the second AC-DC converter is connected between the second power interface and the second power plug via a second cable, both the first power interface and the second power interface are electrically connected with the socket user for being connected with a product to be tested, the first power plug is used for being connected with a power supply at a standby site, and the second power plug is used for being connected with a test station power supply. According to the device provided by the invention, the product to be tested can be powered on before entering a test station, and is uninterruptedly powered during a process of moving to the next test station, so that the product to be tested is prevented from being frequently powered off and restarted, and test efficiency can be effectively improved.
Description
technical field [0001] The embodiments of the present invention belong to the technical field of testing, and in particular relate to a dual-DC test 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 multipl...
