Embodiment

[0014] Through the device of the present invention, the connector is connected in series between the main board power input socket and the power cable plug, and the voltage of each power supply is measured by using the measuring socket connected in parallel with the connector, without inserting the probe of a measuring device such as a multimeter Insert it into the wire hole on the top of the power plug to measure the output voltage of the power supply in real time without causing unnecessary damage to the power interface. At the same time, there is no need to find the power output circuit on the main board for measurement, which greatly simplifies the complexity of measurement.

[0015] Using a device that is convenient for measuring the output voltage of the power supply, it can cooperate with a single measuring tool such as a multimeter to measure the voltage from the computer power-on, to the bios post self-test, to the computer entering the system and running the load. Th...

Abstract

The invention provides a device convenient for testing the output voltage of a power supply. A connecting piece is arranged between the plug of an output cable of the power supply and a power supply socket of a main board and is connected in series with the plug and the socket correspondingly, and moreover, the connecting piece is also connected with a test socket with the same plug number and arrangement with the plug and the socket. By the test socket, a common voltage test instrument can be used for testing all output voltages of the power supply electrically and can perform overall real-time voltage test from computer power up, to bios post self detection and to computer load running on a system. A switch is integrated on the connecting piece or a test socket to control the connection and disconnection of a 16th PIN green wire and a 17th PIN black earth wire; and the green wire and the black wire are controlled to be connected or disconnected by the switch so as to test the no-load voltage output condition of the power supply.

Description

technical field [0001] The invention relates to a computer power supply test technology, or a measurement of the output voltage of a power supply applicable to all personal computers, X86 architecture servers and storage. Specifically, it is a device that facilitates the measurement of the output voltage of a power supply. Background technique [0002] It is especially important to test various performances of the power supply. Whether it is parameter measurement in the computer product development stage or fault location in the maintenance process, the output voltage of the power supply is an important indicator that needs to be measured. However, when the power supply is working, the power supply plug is closely connected with the motherboard interface, which is very inconvenient to measure. Several traditional measurement methods have their inevitable shortcomings or limitations. Contents of the invention [0003] The object of the present invention is to provide a de...
