Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a signal testing device for rapid fixation of multiple terminals. Background Technology

[0002] In the field of audio / video conversion technology, the accuracy and efficiency of signal testing have a crucial impact on product quality and market competitiveness. With the diversification and increasing complexity of terminal devices, achieving rapid, stable signal testing across multiple devices has become a significant technical challenge in the industry.

[0003] According to publication number CN210927638U, a wireless terminal signal testing device is disclosed. This device is mainly for signal testing of wireless terminals. The device includes a control and measurement host electrically connected to at least two analysis and testing devices, a signal line control module, and a test signal transceiver module. The signal line control module is electrically connected between the signal test ports of the at least two analysis and testing devices and the test signal transceiver module. The control and measurement host controls the corresponding analysis and testing device to perform the signal test, and controls the signal line connections in the signal line control module and the test signal transceiver module, thereby establishing a test signal connection between the analysis and testing device performing the signal test and the wireless terminal under test placed in a microwave anechoic chamber. However, this device lacks a rapid fixation mechanism for multiple terminal devices, making it unable to achieve stable and efficient signal testing of multiple terminal devices simultaneously, and thus failing to meet the needs of large-scale production and testing. Utility Model Content

[0004] The purpose of this invention is to provide a signal testing device for rapid fixation of multiple terminals, in order to solve the problem mentioned in the background art that existing signal testing devices cannot achieve stable and efficient signal testing of multiple terminal devices at the same time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A signal testing device for rapid fixation of multiple terminals includes a multi-terminal test cabinet for testing audio and video conversion signal playback. Several sets of measurement and control hosts are installed on the outer wall of the multi-terminal test cabinet, and a negative pressure fan is installed on the top of the multi-terminal test cabinet. The multi-terminal test cabinet has several sets of terminal fixing slots on one side for fixing the terminal under test. The inner wall of the terminal fixing slot is equipped with a test interface that is plugged into the test port of the terminal under test. The test interface is connected to the test and control host. The air inlet of the negative pressure fan is connected to a negative pressure pipe, and the negative pressure pipe is connected to branch pipes that are the same number, corresponding in position, and connected to the terminal fixing slots.

[0006] Preferably, each branch pipe is equipped with a control gate valve, allowing independent control of the negative pressure environment of each terminal fixing slot. This design enables users to adjust or shut off the negative pressure of specific slots as needed, thereby achieving more flexible and precise control of the terminal fixing and testing environment.

[0007] Preferably, the measurement and control host includes an analysis and testing module, a signal line control module, and a test signal transceiver module. The host integrates these three modules, achieving integration and automation of the signal testing process. This design not only improves testing efficiency but also ensures the stability and reliability of the testing process.

[0008] Preferably, the analysis and testing modules consist of at least two sets, each used to execute different signal test items. Setting up at least two sets of analysis and testing modules allows for the simultaneous execution of multiple different signal test items. This multi-task parallel processing capability significantly improves testing efficiency and meets the needs of complex testing scenarios.

[0009] Preferably, the measurement and control host is electrically connected to the analysis and testing module, the signal line control module, and the test signal transceiver module. The signal line control module is electrically connected between the signal test port of the analysis and testing module and the test signal transceiver module. This electrical connection design between the measurement and control host and each module, as well as the connection of the signal line control module between the signal test port and the test signal transceiver module, ensures the accuracy and efficiency of signal transmission. This design allows test signals to be transmitted smoothly between the modules, improving the accuracy and response speed of the test.

[0010] Preferably, the signal line control module includes a first signal line control circuit, a second signal line control circuit, and a signal amplification circuit, enabling the module to more flexibly control the signal transmission path and amplify weak signals. This not only improves the stability of signal transmission but also enhances the test system's ability to detect weak signals.

[0011] Preferably, the test signal transceiver module is connected to the test interface. This direct connection ensures that the test signal can be transmitted directly and accurately to the terminal under test. This design simplifies the signal transmission path, reduces signal interference and loss, and improves the accuracy and reliability of the test.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: In this multi-terminal rapid fixation signal testing device, a negative pressure environment is formed by the multi-terminal test cabinet and several sets of measurement and control hosts installed on its outer wall, along with the negative pressure fan installed on the top and the connected negative pressure pipes and branch pipes. This allows the terminal under test to be attracted and firmly fixed by the negative pressure. At the same time, this negative pressure environment helps the test interface to be tightly plugged into and fixed with the test port on the terminal under test, ensuring the stability of the signal connection. Several sets of terminal fixing slots opened on one side of the multi-terminal test cabinet provide convenient installation positions for the terminal under test. Through the dual guarantee of negative pressure fixation and plug-in fixation, the rapid and stable installation of multiple sets of terminals under test and the stable testing of signals are realized, significantly improving the testing efficiency and accuracy.

Branch pipes 32, the same number and corresponding in position as the terminal fixing slots 11, are connected to the negative pressure pipe 31.

Several sets of terminal fixing slots 11 opened on one side of the multi-terminal test cabinet 10 provide convenient installation positions for the terminal under test 40. Through the dual guarantee of negative pressure fixing and plug-in fixing, the rapid and stable installation of multiple sets of terminals under test 40 and the stable testing of signals are realized, significantly improving the testing efficiency and accuracy.

Next, turn on the negative pressure fan 30 on the top of the multi-terminal test cabinet 10, and adjust the control valve 33 on each branch pipe 32 as needed to create a suitable negative pressure environment in the terminal fixing slot 11, so that the terminal under test 40 is firmly adsorbed and the test interface 12 is plugged into the test port 41 and fixed. Then, the measurement and control host 20 is started, and its internal analysis and test module, signal line control module and test signal transceiver module begin to work together; the signal line control module is responsible for managing the signal transmission path, and the test signal transceiver module receives the signal from the terminal under test 40 through the test interface 12 and transmits it to the analysis and test module for various tests and analyses; During the testing process, different analysis and testing modules can be selected to execute specific test items as needed.
