[0029] An embodiment of the present invention provides a test board 100, referring to Figure 1 , the test board 100 includes a first test interface 1, a second test interface 2, two groups of loads, a PD chip and a display module, the first test interface 1 and the second test interface 2 are used to connect a POE power supply device, the PD chip is used to identify the power of the load, and the display module is used to display the power of the load;

[0030] The first test interface 1 is connected to a group of the load, the PD chip, and the display module to form a first test unit, and the second test interface 2 is connected to two groups of the load, the PD chip, and the display module to form a second test unit.

[0031] The second test unit of the utility model has a different load from the first test unit. The first test unit and the second test unit can be used to test POE power supply devices with different output powers respectively, which is more flexible to use and has better versatility.

[0032] In this embodiment, the first test unit is used to test a POE power supply device that complies with the IEEE 802.3af power supply standard, and the second test unit is used to test a POE power supply device that complies with the IEEE 802.3at power supply standard.

[0033] Each group of the loads includes four cement resistors 31. The cement resistor 31 is a resistor device, which is often used for the purpose of limiting or distributing current in a circuit. Its appearance is similar to a rectangular block and is usually made of cement or ceramic materials. The cement resistor 31 has a high power dissipation capability and a low resistance value, and is suitable for high-power circuits or applications that need to resist large currents. The test board 100 shares the voltage output by the POE power supply device through the cement resistor 31, and then identifies the power of the cement resistor 31 through the PD chip, thereby obtaining the output power of the POE power supply device.

[0034] The display module includes a plurality of LED lights 51 for displaying the power of the load, and the plurality of LED lights 51 are electrically connected to the PD chip respectively. Specifically, the output power of the POE power supply device of the IEEE802.3af power supply standard is less than or equal to 15.4W, and the output power of the POE power supply device of the IEEE802.3at power supply standard is less than or equal to 30W. The principle of the LED lights 51 displaying the load power is as follows: after the PD chip identifies the power of the load, the corresponding number of LED lights 51 are controlled to light up according to the power value. For example, one LED light 51 lights up to represent 5W, and three LED lights 51 light up to indicate that the power of the load is 15W. Optionally, the number of the LED lights 51 is set to 5.

[0035] The first test interface 1 and the second test interface 2 are RJ45 interfaces. The RJ45 interface is a common network connection interface used to connect computer network devices, such as computers, routers, switches, etc. This interface is commonly used in Ethernet networks and can transmit data and power. The RJ45 interface usually uses an 8P8C socket with 8 metal contacts for inserting network cables. This interface is usually connected using twisted pair cables or network cables (such as Cat5e, Cat6, etc.), and the device and the network are connected together through a plug. The RJ45 interface is usually used to transmit Ethernet signals, including local area network connections, wide area network connections, and telephone line connections. It has become one of the most commonly used interface standards in today's network equipment. It is easy to use and has strong stability and reliability.

[0036] Another embodiment of the present invention further provides a tester 200, see Figure 2 and Figure 3 , the tester 200 includes the test board 100 described above.

At least two of the test boards 100 are connected in sequence and connected to the circuit board 6, so that at least two of the test boards 100 can share the output voltage of the POE power supply device, so the tester 200 can be used to test a POE power supply device with a larger power, and the sum of the power values ​​measured by at least two of the test boards 100 is the output power of the POE power supply device.

[0037] Specifically, the third test interface 61 is an RJ45 interface.

[0038] In this embodiment, the number of the test boards 100 is set to four, wherein a third test unit consisting of three test boards 100 and a circuit board 6 is used to test POE power supply equipment of the IEEE802.3bt power supply standard, and the other one works alone to test POE power supply equipment of the IEEE802.3af power supply standard or POE power supply equipment of the IEEE802.3at power supply standard.

[0039] It should be noted that the number of test boards 100 included in the tester 200 is not limited here, and the number of test boards 100 can be selected according to the power of the POE power supply device to be tested. Since the more test boards 100 included in the tester 200, the greater the power that can be tested by the tester 200, the measurable power of the tester 200 can be increased by increasing the number of test boards 100.

[0040] One end of the test board 100 is provided with a Phoenix terminal 11, and the Phoenix terminals 11 of the three test boards 100 are connected in sequence by wires. The Phoenix terminal 11 is an electronic component connector, which is commonly used for connection on the circuit board 6 and is also widely used for connection of various electronic devices. The housing is usually fixed on the circuit board 6, and the plug is inserted into the housing to complete the circuit connection. The Phoenix terminal 11 is generally used for low voltage and low current applications.

[0041] The tester 200 further includes a single-pass copper column 21. The four corners of the test board 100 are provided with first mounting holes 12 for the single-pass copper column 21 to extend into. The three test boards 100 are connected through the single-pass copper column 21. The three test boards 100 can be assembled together through the single-pass copper column 21, so that the Phoenix terminals 11 of the three test boards 100 are located at the same end and close to each other, making the connection between the Phoenix terminals 11 of the three test boards 100 more convenient, requiring a shorter wire length, and facilitating the connection of the subsequent expanded test boards 100.

[0042] The tester 200 further includes a screw 22, and the circuit board 6 is provided with two second mounting holes 62 corresponding to the positions of the two first mounting holes 12, and the single-pass copper column 21 passes through the second mounting holes 62 and is connected to the screw 22. The circuit board 6 is assembled with at least two test boards 100 by the screw 22, and installation and disassembly are convenient. Specifically, the circuit board 6 is installed on the upper side of the test board 100, and the circuit board 6 is electrically connected to the uppermost test board 100.

[0043] The tester 200 further includes a base 23, and the base 23 is provided with a stud 24 corresponding to the first mounting hole 12, and the stud 24 is used to connect with the single-pass copper column 21. By providing the base 23, the overall structure of the tester 200 is more stable, and the placement is stable, and it is not easy to collapse after the test board 100 is expanded.
