Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present utility model, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

The embodiment of the utility model provides a testing tool for master-slave equipment, as shown in fig. 1 and 2, comprising:

a PCB 101;

a power supply end 102 disposed on the PCB 101;

a main device motherboard 103 mounted on the PCB 101, and a power supply end 102 connected to the main device motherboard 103 via a connection line L disposed on the PCB 101;

a plurality of power boards 104, the power supply terminal 102 being connected to each power board 104 through a branch line Y drawn out by a connection line L;

the number of the slave device mainboards is equal to that of the power boards 104, the plurality of the slave device mainboards 105 are arranged on the PCB 101, and each power board 104 is correspondingly connected with one slave device mainboard 105.

By adopting the test fixture, 12V voltage is provided from the outside, the power is directly supplied to the main equipment main board 103 through the power supply end 102 on the PCB 101, and meanwhile, the power can be supplied to the auxiliary equipment main board 105 through the power board 104 corresponding to each auxiliary equipment main board 105. The power board 104 is used for converting a 12V power supply into a 3.3V voltage and providing the voltage to the slave device motherboard 105.

In an alternative embodiment, a switch is provided on the connection line L near the power supply terminal 102 for controlling the power supply switch to the master device motherboard 103 or any slave device motherboard 105. For example, the switch may be controlled to power the host motherboard 103 alone when a host device test is required. When testing the slave device No. 1, the switch may be controlled to supply power to the slave device motherboard No. 1 alone, and of course, the master device and the slave device may also be simultaneously supplied with power. The power supply is realized through arranging the connecting wire L and the branch line Y, so that the phenomena of short circuit and the like caused by line confusion in the prior art are avoided, and the testing efficiency is improved.

In an alternative embodiment, a power indicator 106 corresponding to each power board 104 is further provided on the PCB 101, and each power indicator 106 is connected to the corresponding power board 104, and indicates through the corresponding power indicator 106 when the power board 104 fails and cannot be effectively powered. Specifically, when the power panel 104 fails, the power indicator 106 is not lit; when the power panel 104 is normal, the power indicator lamp 106 is turned on.

In an alternative embodiment, the main device motherboard 103 is mounted on the PCB board 101 through a first set of copper pillars, specifically, the four corners of the main device motherboard 103 are mounted and fixed through the first set of copper pillars.

Correspondingly, as shown in fig. 3, a side view of the slave device motherboard 105 and the power board 104 is shown. Each slave device motherboard 105 is mounted on the PCB board 101 through the third set of copper pillars 109, wherein, since the slave device motherboard 105 is correspondingly connected with the power board 104, each power board 104 is located below each slave device motherboard 105, so that the height of the second set of copper pillars 108 is lower than the height of the third copper pillars 109, which is beneficial to saving the arrangement size, and more other devices can be arranged on the PCB board 101.

In an alternative embodiment, the test fixture further comprises: a connector 107, the connector 107 is disposed at a connection portion of each branch line Y and the power panel 104. Therefore, the number of connectors 107 is the same as the number of power boards 104. The branch line Y is connected with the power board 104 through a connector 107, so as to supply power to the corresponding slave device motherboard 105.
