[0027] like Figure 1 and Figure 2 As shown, the power board testing equipment includes a fixture body 10, a circuit component 20 and a test display component 30, wherein the test display component 30 includes a voltmeter 31 and an ammeter 32, and during testing, the voltmeter 31 and the ammeter 32 are electrically connected to the circuit component 20 and the power board 90, so that the test results of the power board 90 are displayed.
[0028] The fixture body 10 includes a base 11 and a pressure plate assembly 12, wherein the upper surface of the base 11 forms a fixed space 1101, and the fixed space 1101 is used to fix the power board body 91. The pressure plate assembly 12 is fixed to the upper surface of the base 11, and the pressure plate assembly 12 includes a pressure plate 121, and the pressure plate 121 can be pressed on the top of the power board body 91 and connect the power board body 91 to the circuit, so as to directly perform the power board LED test and the voltage board LED test by powering on.
[0029] It can be understood that the power board body 91 and the voltage board 92 are electrically connected. Therefore, when the power board body 91 is pressed by the pressure plate 121 and connected in the circuit, the user can directly perform the power board LED test and the voltage board LED test as long as the power is turned on, and the measured data can be displayed on the test display component 30.
[0030] The base 11 of the fixture body 10 has an installation space 1102, and the circuit component 20 can be installed in the installation space 1102, and when the power board body 91 is fixed in the fixed space 1101 and pressed by the pressure plate assembly 12, the power board body 91, the circuit component 20 and the test display component 30 are energized, so that the user can test the performance of the power board body 91 and display it on the test display component 30.
[0031] Preferably, if Figures 2 to 4As shown, the circuit component 20 includes a power supply 21, a power converter 22, a single-chip microcomputer development board 23 and a power adapter board 24, wherein the power adapter board 24 is installed below the pressure plate 121, and the power adapter board 24 has a plurality of test probes 241, and the test probes 241 are arranged below the power adapter board 24, so that when the pressure plate 121 presses the power board body 91, the test probes 241 connect to the test points on the power board body 91, and then the power board body 91 connects to the circuit.

The current passing through the power board body 91 flows back to the single-chip development board 23 after passing through the power adapter board 24 to form a complete circuit. At the same time, by specifically changing the voltage through the voltmeter 32, the performance of the power board body 91 can be measured and displayed on the test display component 30.
[0033] It is worth mentioning that the voltmeter 32 can change the voltage to ±30V, and the power adapter board 24 can form multiple gears through switches, so as to test the performance of the power board body 91 from multiple aspects.
[0034] It can be understood by those skilled in the art that after the power board body 91 is fixed in the fixed space 1101, the pressure plate assembly 12 presses the power board body 91, so that the power board body 91 is connected to the entire circuit, and the voltage of 5V or 12V can be used by the voltmeter 32 to test the performance of the power board body 91 at 5V or 12V, and displayed on the test display assembly 30.

In this way, the power board fixture can test the performance of the power board body 91 in multiple situations at one time.
[0035] Preferably, the power adapter board 24 has multiple gear interfaces, and the multiple gear interfaces of the power adapter board 24 are arranged to be connected in the circuit through a switch, and each of the gear interfaces can be controlled by the switch, so that the user can adjust the gear through the switch, thereby completing the monitoring of multiple gears of the power board main body 91.
[0036] It can be understood that, through the adjustment of voltage and multiple gears, the user can use the power board testing equipment to test the performance of the power board body 91 from multiple directions at one time, making the performance test of the power board body 91 more comprehensive.
[0037] Preferably, the power board body 91 has a plurality of fixing holes 901, and the base 11 forms a plurality of limiting columns 111, and the limiting columns 111 are arranged on the bottom wall forming the fixed space 1101 corresponding to the fixing holes 901, so that when the power board body 91 is placed in the fixed space 1101, the limiting columns 111 pass through the fixing holes 901 to fix the power board body 91.

[0041] Preferably, the pressure plate assembly 12 further includes a plurality of elastic members 124, which are distributed below the pressure plate 121 and are elastic. When the pressure plate 124 presses against the power board body 91, the elastic members 124 first contact the power board body 91, so that the pressure on the power board body 91 increases slowly, thereby preventing the pressure directly provided by the pressure plate 124 from crushing the power board body 91.
[0042] As an example, the elastic member 124 is implemented as an elastic column.
[0043] It is worth mentioning that, since the voltage plate 92 is electrically connected above the power plate body 91 , the elastic member 124 and the pressure plate 121 are arranged to avoid the voltage plate 92 to avoid damaging the voltage plate 92 .
[0044] Preferably, the circuit component 20 includes a transformer 25, which is electrically connected between the power supply 21 and the power converter 22, so that the voltage input to the power converter 22 becomes smaller, thereby preventing the voltage input to the power converter 22 from exceeding the adjustment range of the power converter 22.
[0045] As an example, the transformer 25 is implemented as a toroidal transformer.

[0047] Preferably, the base 11 is configured to be openable so that the installation space 1102 is connected to the outside, so that when a problem occurs with the circuit assembly 20 , a user can open the base 11 to repair the circuit assembly 20 .
