Detailed Implementation
[0022] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.
[0023] Example: An auxiliary testing device for optical modules, such as... Figures 1-8As shown, the system includes a base plate 1, support blocks 101, a PCBA board 2, a test cage 3, fixing blocks 4, connectors 41, wire harness clamps 5, a constant temperature chamber 14, a chamber cover 15, an integrated thermoelectric cooler 16, and a limiting assembly. Multiple support blocks 101 are connected to the bottom of the base plate 1, and these support blocks 101 are inverted U-shapes. The PCBA board 2 is located on the upper side of the base plate 1. The PCBA board 2 is responsible for processing the data received from the optical module and performing necessary performance tests. A test cage 3 is installed on the rear side of the base plate 1. The test cage 3 is used for performance testing of the optical module. Multiple fixing blocks 4 are connected to the PCBA board 2, and multiple connectors 41 are installed on the PCBA board 2. Each connector 41 has a wire harness clamp inserted into its outer side. The head 5 and wire harness clamp 5 are used to fix the connector 41. A constant temperature chamber 14 is provided on the outside of the base plate 1. The constant temperature chamber 14 is used to simulate different working environment conditions (such as temperature changes) to ensure that the optical module can be tested for reliability in various environments. A cover 15 is placed on the upper side of the constant temperature chamber 14 to close the constant temperature chamber 14, prevent external interference, and maintain the stability of the internal environment of the constant temperature chamber 14. The cover 15 is equipped with a handle. An integrated thermoelectric cooler 16 is installed on the right side of the constant temperature chamber 14. The integrated thermoelectric cooler 16 is used to precisely regulate the temperature inside the constant temperature chamber 14 to simulate the temperature conditions under actual operating environment. Limiting components are provided inside the fixing block 4 and outside the wire harness clamp 5. The limiting components include... The system comprises connecting block 6, card holder 7, anti-slip pad 71, elastic element 8, guide frame 9, magnetic block 91, first magnetic plate 10, second magnetic plate 11, third magnetic plate 12, and fourth magnetic plate 13. Each fixing block 4 contains two magnetic blocks 91, which magnetically attract to securely connect the fixing block 4 to the guide frame 9. A guide frame 9 is connected between the outer sides of every four magnetic blocks 91. Each guide frame 9 has two connecting blocks 6 connected to it, ensuring the card holder 7 remains stable during sliding. A card holder 7 is slidably connected between every two connecting blocks 6. Each card holder 7 is inserted into and engages with a corresponding fixing block 4 and magnetic block 91, securing the guide frame 9. Positioning ensures that the guide frame 9 will not shift during testing. Each card holder 7 is connected to an anti-slip pad 71. Each connecting block 6 is connected to the corresponding card holder 7 with an elastic element 8. Each guide frame 9 has two first magnetic plates 10 on its upper side and two third magnetic plates 12 on its lower side. Each wire harness clamp 5 has two second magnetic plates 11 on its upper side, and each second magnetic plate 11 is magnetically connected to the corresponding first magnetic plate 10. Each wire harness clamp 5 has two fourth magnetic plates 13 on its lower side, and each fourth magnetic plate 13 is magnetically connected to the corresponding third magnetic plate 12. Through magnetic adsorption, the stability of the wire harness clamp 5 is further enhanced, preventing the wire harness clamp 5 from loosening or falling off.
[0024] When this device is needed to perform auxiliary testing on an optical module, the operator first removes the cover plate and carefully places the optical module to be tested on the PCBA board 2, ensuring that the optical module is correctly positioned. Then, the operator inserts the optical module into one side of the test cage 3 and connects the wiring harness on the other side of the optical module to multiple connectors 41, ensuring that all connections are secure and reliable. Subsequently, the operator pulls the card holder 7 upward, stretching the two elastic elements 8. After the card holder 7 moves to the appropriate height, the operator pushes the multiple magnetic blocks 91 on the guide frame 9 into the corresponding fixing blocks 4, ensuring that the multiple magnetic blocks 91 are fully embedded in the corresponding fixing blocks 4. To provide stable support, the operator then releases the card holder 7. Under the reset action of the two elastic elements 8, the card holder 7 moves downward back to its initial position. At the same time, multiple magnetic blocks 91 are firmly fixed in the corresponding fixing blocks 4, achieving stable installation of the guide frame 9. Next, the operator aligns the wire harness clamp 5 with the connector 41 and pushes the wire harness clamp 5 towards the connector 41. When the wire harness clamp 5 moves to contact the multiple magnetic blocks 91 and successfully mates with the connector 41, the two first magnetic plates 10 contact the two second magnetic plates 11 and attract each other through magnetic force. At the same time, the two third magnetic plates 12 and the two fourth magnetic plates 13 also contact each other. The wire harness clamp 5 is securely fixed by magnetic attraction. Repeating this process allows for the installation of other guide frames 9 and wire harness clamps 5, ensuring all connections are reliable and secure. After the optical module and its related components are installed and secured, the operator activates the test cage 3 and replaces the cover 15 to prevent external interference and maintain the stability of the internal environment of the constant temperature chamber 14. At this point, the test cage 3 begins performance testing of the optical module. Throughout the testing process, the PCBA board 2 processes the data received from the optical module and performs necessary performance evaluations, such as transmit power, receive sensitivity, and wavelength accuracy. To measure key parameters and simulate different working environment conditions, and to ensure the accuracy and reliability of test results, the staff then activated the integrated thermoelectric cooler 16. The integrated thermoelectric cooler 16 can precisely adjust the temperature inside the constant temperature chamber 14, thereby simulating temperature conditions under various actual operating environments and ensuring that the optical module can operate normally under different temperature conditions. As the test process progresses, the PCBA board 2 will monitor the various performance indicators of the optical module in real time and record the data for subsequent analysis. When all the scheduled test items of the optical module are completed, the staff will turn off the test cage 3 and the integrated thermoelectric cooler 16 in sequence, ending the entire test process.
