[0023] To make the above and other features and advantages of this utility model clearer, the utility model will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art, and are exemplary only, not restrictive.

[0024] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, a multi-interface testing device for a data storage protection module is provided, comprising a cover plate 1, a test circuit board 2, and a housing 3.

[0025] Multiple test interfaces 201 are installed on at least one side of the test circuit board 2, and each test interface 201 is configured with a status indicator light 202. The status indicator light 202 is mounted on the test circuit board 2.

[0026] To increase the number of test data storage protection modules, in this embodiment, multiple test interfaces 201 are installed on both sides of the test circuit board 2. Each test interface 201 is configured with a status indicator light 202. Eight test interfaces 201 and eight status indicator lights 202 are installed on each side of the test circuit board 2. Figure 2 As shown.

[0027] Furthermore, a power supply interface 203 and a data transmission interface 204 are also installed on the test circuit board 2. The power supply interface 203 is used to connect a power supply to power the test circuit board 2. The data transmission interface 204 is used to connect to a PC, enabling the test circuit board 2 to exchange data with the PC.

[0028] It should be understood that the test circuit board 2 integrates a test circuit (not shown in the figure), which is electrically connected to multiple test interfaces 201, multiple status indicator lights 202, and a power supply interface 203. In some embodiments, the test circuit board 2 integrates a communication module (not shown in the figure), which is electrically connected to the test circuit board and to the data transmission interface 204, so that the test circuit board 2 can exchange data with the PC.

[0029] In some embodiments, the test circuit board 2 also integrates a voltage management unit for monitoring and protecting the voltage and current of the test circuit of the test circuit board 2. For example, the voltage management unit monitors the voltage and current input to the test circuit board 2 in real time, and protects against and isolates abnormal conditions such as overvoltage and overcurrent.

[0030] like Figure 2 As shown, according to an embodiment of the present invention, a plurality of first openings 301 corresponding one-to-one with the test interface 201 and a plurality of second openings 302 corresponding one-to-one with the status indicator lights 202 are provided on one side of the housing 3. A third opening 303 corresponding to the power supply interface 203 and a fourth opening 304 corresponding to the data transmission interface 204 are also provided on the housing 3.

[0031] The test circuit board 2 is placed inside the housing 3. Each test interface 201 is embedded in a corresponding first opening 301, and each status indicator 202 is embedded in a corresponding second opening 302. The power supply interface 203 is embedded in a third opening 303, and the data transmission interface 204 is embedded in a fourth opening 304.

[0032] Furthermore, studs are provided inside the housing 3, and the test circuit board 2 is placed inside the housing 3 and fixed to the housing 3 by bolts.

[0033] According to an embodiment of the present invention, a high-performance graphite thermal conductive material is filled between the bottom of the test circuit board 2 and the bottom of the housing 3 to improve the heat dissipation effect of the test circuit board 2.

[0034] Furthermore, the housing 3 is made of aluminum alloy. The heat generated by the test circuit board 2 is quickly conducted to the housing 3 made of aluminum alloy through the high-performance graphite thermal conductive material filled between the bottom of the test circuit board 2 and the bottom of the housing 3. The housing 3 made of aluminum alloy then quickly conducts the heat away, further improving the heat dissipation effect of the test circuit board 2.

[0035] like Figure 2 As shown, cover plate 1 covers and connects to housing 3. A sealing ring is provided around the connection between cover plate 1 and housing 3 to waterproof and dustproof the inside of housing 3, preventing damage to the test circuit board 2.

[0036] Furthermore, the cover plate 1 is a transparent cover plate to facilitate observation of the status of the test circuit board 2 inside the housing 3.

[0037] The following describes the usage process of the multi-interface testing device for data storage protection module provided by this utility model.

[0038] When multiple data storage protection modules need to be tested, connect the multiple data storage protection modules to multiple test interfaces 201, connect the power supply interface 203 to the power supply, and connect the data transmission interface 204 to the PC.

[0039] The test circuit board 2 is controlled to start the test via the PC-side control program. During the test, the test status of the data storage protection module under test is displayed by the status indicator 203 corresponding to the test interface 201.

[0040] For example, if the status indicator 203 corresponding to a certain test interface 201 is not lit, it indicates that the data storage protection module connected to the test interface 201 has not been successfully connected to the test interface 201.

[0041] When the status indicator 203 corresponding to a certain test interface 201 turns red, it indicates that the data storage protection module connected to that test interface 201 may be malfunctioning.

[0042] When the status indicator 203 corresponding to a certain test interface 201 turns green, it indicates that the data storage protection module connected to that test interface 201 is functioning well.

[0043] During the test, the test circuit board 2 transmits the test data to the PC through the data transmission interface 204, so that the testers can analyze the test results of the data storage protection module.

[0044] This invention enables simultaneous testing of multiple data storage protection modules, effectively improving testing efficiency, reducing testing costs, increasing production efficiency, and lowering production costs. The invention features a simple structure, small size, and ease of use.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
