Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electronic appliances, concretely relates to a switching PCB board of hard disk maintenance test equipment, aims at solving the problem of poor compatibility, easy failure and inconvenient maintenance and replacement of the switching PCB board in the existing hard disk test maintenance equipment. BACKGROUND

[0002] The existing hard disk test maintenance equipment usually uses a switching PCB board to connect the hard disk and the test equipment. However, the existing switching PCB board has the following problems:

[0003] Poor compatibility: the existing switching PCB board can usually only be compatible with one type of hard disk interface, and cannot adapt to the test requirements of multiple hard disk models.

[0004] Easy failure: since the hard disk test equipment needs to frequently plug and unplug the hard disk, the sockets on the switching PCB board are prone to wear and tear, which may cause failure.

[0005] Inconvenient maintenance: the sockets on the existing switching PCB board are directly soldered on the PCB board, and once the sockets are damaged, the entire PCB board must be replaced, increasing the maintenance cost and time.

[0006] In the existing technical solution, the design of the switching PCB board is relatively simple, lacking flexibility and maintainability. For example, the existing switching PCB board usually uses fixedly soldered sockets, which cannot be quickly replaced if damaged, resulting in high maintenance cost and low efficiency. SUMMARY

[0007] In view of the deficiencies of the prior art, the utility model provides a switching PCB board of a hard disk maintenance test equipment.

[0012] In one preferred embodiment of the present disclosure, the small plate is provided with a switch for selecting the conduction of the hard disk.

[0013] In one preferred embodiment of the present disclosure, the main board is provided with a power jack for supplying power to the main board, and is also provided with a USB jack for connecting the main board with a computer.
