[0027] The above-mentioned test interface includes an interface with a maximum number of pin lines that needs to be tested twice. A test line selection switch is also provided on the first test block or the second test block to perform one or two tests on the test interface according to the number of test cables.

[0028] One side of the first test block 1 is provided with an RJ11 interface 15, a JACK6.35MM interface 16, an RCA interface 17, and a JACK3.5MM interface 18. Correspondingly, one side of the second test block 2 is provided with an RJ11 interface 25, a JACK6.35MM interface 26, an RCA interface 27, and a JACK3.5MM interface 28.

[0029] The other side of the first test block 1 is provided with a BNC interface 14, a DIN-5P interface 12, and a DIN-8P interface 11. Correspondingly, the other side of the second test block 2 is provided with another BNC interface 24, another DIN-5P interface 22, and another DIN-8P interface 21.

[0030] An HDMI interface 60 is also provided on the surface of the first test block 1 , and correspondingly, another HDMI interface 80 is also provided on the surface of the second test block 2 .

[0031] A test circuit selection switch 41 is provided on the surface of the first test block, which respectively selects the first test route, closes, and the second test route. The test circuit selection switch 41 is used to select the first test route, the second test route for testing, or close the test.

[0032] The surface of the first test block is also provided with a pulse frequency selection switch 42, which respectively selects low speed, normal and fast testing. Therefore, the pulse frequency selection switch can be used to select low speed, normal or fast testing.

[0033] The surface of the first test block is provided with a transparent material 5, and the transparent material 5 is provided with a display bar 51 for indicating the status of each test line of the first test circuit and the second test circuit. In this embodiment, the status indicator light is specifically a light emitting diode.

[0034] A heat dissipation bar 10 is provided on the side of the first test block 1 , and a heat dissipation bar 20 is provided on the side of the second test block 2 .

[0037] The second test block 2 is provided with a test line type selection switch 32 , which is respectively configured as sine wave test, test lead test, and off.

[0038] When you need to test an ordinary cable, first select the test lead test through the line type selection switch 32, and then insert the two test leads (banana plug red 5 and banana plug black) into the test lead test interfaces 45 and 46 to directly test the two ends of the cable. When the buzzer sounds, it means the cable is normal. Otherwise, if the buzzer does not sound, the cable is unqualified.

[0039] When it is necessary to test the audio cable, the two ends of the audio cable are respectively connected to the corresponding interfaces of the first test block and the second test block, and then the audio test is selected by the selection switch 42. Then, the next test method is determined according to the number of audio lines of the audio cable. If the number of audio lines is not greater than 10, the selection switch 42 selects the 1st to 10th test lines for testing. Then, according to the type of the audio line, the pulse time selection switch 41 selects the corresponding pulse time gear, such as fast gear, normal gear or slow gear, and then the clock trigger pulse generation and pulse time control circuit is started. Each audio line is automatically tested in turn by the first calculator and decoder circuit (1-10), and the light-emitting diodes of the left and right indicator circuits are lit in turn to indicate whether they are qualified. If the number of audio lines of the audio cable to be tested is greater than 10, after testing the 1st to 10th audio lines, the selection switch 42 selects the 11th to 19th test lines and the remaining audio lines are tested in the above method.

[0040] When it is necessary to test whether the audio device is qualified, the audio device cable is connected to the audio interface at the same end as the selection switch 32, such as the RCA interface, and then the audio device test is selected through the selection switch 32 to test the audio device.
