Rigorous product testing is essential to ensure product quality during the production process. Currently, existing test stations on the market generally have limitations, particularly in current testing.
[0003] In the prior art, when testing current at a test station, the only way to identify whether the product is charging is through an LED light. Specifically, if current is flowing, a green light will turn on, and if no current is flowing, a red light will turn on.
[0004] This test method cannot accurately detect the current value. It can only determine whether current is flowing, but cannot determine whether the current flowing through the product is within the rated range.
[0005] Therefore, it is necessary to improve the existing test fixture to solve the problem that it cannot determine whether the current flowing through the product is within the rated range.
[0006] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0044] The utility model provides a screen-display test fixture suitable for use in testing headphones, which can effectively solve the problem that existing test fixtures cannot determine whether the current flowing through the product is within a rated range.
[0045] See also Figure 1 In this embodiment, the screen display test fixture includes a fixture body 1, a current detection device, and a display screen 2.
[0046] The fixture body 1 is provided with a test slot 1031 for mounting and fixing the product to be tested; the current detection device is located in the fixture body 1 and is used to detect the current value flowing through the product to be tested; the display screen 2 is installed on the fixture body 1 and is electrically connected to the current detection device to display the current value.
[0047] In the on-screen test fixture provided in this embodiment, when a product under test is placed in the test slot 1031 for testing, the current detection device can detect the current value flowing through the product under test, and then display the current value on the display screen 2. The tester can directly determine whether the current value flowing through the product under test is within the rated range based on the current value displayed on the display screen 2. For example, the current value may be too large, too small, or just within the rated range.
[0048] Therefore, the screen display test fixture provided by the present invention can effectively solve the problem that existing test fixtures cannot determine whether the current flowing through the product is within the rated range.
[0049] The screen display test fixture further includes an indicator light module 3 , a control circuit board, and a buzzer module 4 .
[0050] The control circuit board is electrically connected to the current detection device, display screen 2, indicator light module 3 and buzzer module 4 respectively, and is used to receive the current value detected by the current detection device, and control the lighting state of the indicator light module 3 and the buzzing state of the buzzer module 4.
[0051] Optionally, the indicator light module 3 includes an undercurrent indicator light for indicating that the current value is less than the rated range, a normal indicator light for indicating that the current value is within the rated range, and an overcurrent indicator light for indicating that the current value is greater than the rated range. Furthermore, the undercurrent indicator light, the normal indicator light, and the overcurrent indicator light have different lighting colors.
[0052] The buzzer module 4 includes an undercurrent buzzer for indicating that the current value is less than the rated range, a normal buzzer for indicating that the current value is within the rated range, and an overcurrent buzzer for indicating that the current value is greater than the rated range. Furthermore, the buzzer frequencies of the undercurrent buzzer, normal buzzer, and overcurrent buzzer are different.
[0053] For example:
[0054] When the current value is less than the rated range, the red undercurrent indicator light will light up and the other indicators will go out. At the same time, the undercurrent buzzer will emit a very rapid "beep, beep..." cycle of beeps, and the other buzzers will remain silent.
[0055] When the current value is within the rated range, the green normal indicator light is on and the other indicators are off. Synchronously, the normal buzzer emits a long beep and the other buzzers are silent.
[0056] When the current value is less than the rated range, the blue overcurrent indicator light turns on and the other indicators turn off. Synchronously, the overcurrent buzzer emits a long and short beeping sound of "di-di-di-di-..." and the other buzzers remain silent.
[0057] Testers can directly know the test status of the product under test based on the color of the indicator light and / or the beeping frequency of the buzzer, without having to stay by the screen-display test fixture.
[0058] In this embodiment, the fixture body 1 includes a fixture base and a replaceable carrier 103. Furthermore, the fixture base includes a bottom box 101 and a top cover 102, and the current detection device is located in a space surrounded by the bottom box 101 and the top cover 102.
[0059] The top surface of the top cover 102 is provided with a mounting groove 1021, and the mounting groove 1021 is provided with a conductive contact 104 electrically connected to the current detection device; the interchangeable carrier 103 can be detachably installed in the mounting groove 1021 (for example, the interchangeable carrier 103 is magnetically connected, interference fit connected or snap connected to the top cover 102, etc.), and the interchangeable carrier 103 is provided with a carrier probe 105 for electrically connecting the conductive contact 104 and the product to be tested; wherein, the test slot 1031 is located at the top of the interchangeable carrier 103.
[0060] The interchangeable carrier 103 is detachably connected to the fixture base. When different products to be tested need to be tested, it is only necessary to replace the interchangeable carrier 103 with a test slot 1031 of a different shape. The fixture base, current detection device, display screen 2, etc. can be reused, which is conducive to improving the versatility of the screen display test fixture and reducing the testing cost.
[0061] In summary, the screen display test fixture provided in this embodiment has the following beneficial effects:
[0062] ① Accurate detection: Able to detect and display current values in real time to ensure that the product current is within the rated range.
[0063] ② Intuitive feedback: Through the different states of the indicator light and buzzer, the tester can quickly and intuitively understand the test results.
[0064] ③ Improve efficiency: Automated current detection and result display reduce manual intervention and improve test efficiency.
[0065] ④ Strong versatility: Through the design of the interchangeable carrier 103, the fixture can be adapted to the testing of different models of products, thereby reducing production costs.
[0066] ⑤ Easy to operate: Testers do not need to monitor continuously and can operate according to the prompts of indicator lights and buzzers, which simplifies the testing process.
[0067] In summary, the screen display test fixture provided by the present invention has high practical value and broad application prospects in the production testing of electronic products.
