Description

Technical Field

[0001] This utility model relates to the field of connector testing technology, and in particular to a connector testing system. Background Technology

[0002] Connectors, also called plugs, include male and female connectors. After being plugged in, male and female connectors can transmit current or signals and play an indispensable role in the normal operation of electronic equipment.

[0003] During product assembly, after the male and female connectors are plugged in and connected, it is necessary to check whether the connection status is normal to avoid quality problems after leaving the factory due to floating phenomenon, such as poor contact, signal interruption, etc., which seriously affect the performance and service life of electronic devices.

[0004] Currently, there are two main methods for this type of inspection. One method is manual visual inspection, which relies on the inspector's observation and experience. However, manual inspection is easily affected by factors such as fatigue, differences in vision, and subjective factors, making it difficult to guarantee the accuracy and stability of the results, and the efficiency is also relatively low. The other method uses infrared equipment to detect the height of the male and female connectors to identify the connection status. Although this method utilizes technology to some extent, it also has limitations, and its accuracy still needs to be improved.

[0005] Therefore, improvements to existing technologies are necessary.

[0010] The connector includes a male connector and a female connector. The male connector has a plurality of first functional pins and two first detection pins. The metal contact height of the first detection pins is smaller than that of the first functional pins, so that after the male connector is connected to the female connector, the contact distance between the first detection pins and the female connector is smaller than the contact distance between the first functional pins and the female connector.

[0026] When the motherboard is being tested, the recording module records the test data of the connection status between the male connector and the female connector, including the number of normal connections and the number of abnormal connections.

[0027] Furthermore, the connector detection system also includes a communication module;

[0028] The communication module is connected to the motherboard;

[0029] When the motherboard is being tested, the communication module transmits the detection data of the connection status between the male connector and the female connector to an external device.

[0030] Furthermore, the connector detection system also includes a display module;

[0031] The display module is connected to the motherboard;

[0032] When the motherboard is being tested, the display module displays the test data on the connection status of the male connector and the female connector.

[0034] This invention provides a connector testing system that, by setting a first detection pin and a second detection pin on the male and female connectors respectively, and using the motherboard's detection port to monitor the consistency of the voltage levels of these two detection pins, can quickly and accurately determine whether the connector connection is normal. This testing method overcomes the subjectivity and inefficiency of traditional manual visual inspection, while also avoiding the limitations of infrared detection equipment in terms of recognition accuracy.

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0057] Please refer to Figure 1-8 This utility model provides a connector testing system, including a motherboard 1 and a connector 2 to be tested;

[0058] The connector 2 to be tested further includes two components: a male connector 21 and a female connector 22. The male connector 21 is equipped with several first functional pins 23 (used for transmitting signals or current during normal operation) and two first detection pins 24. By design, the height of the metal contacts of the first detection pins 24 is intentionally set to be less than the height of the metal contacts of the first functional pins 23. This design aims to ensure that, after the male connector 21 and the female connector 22 are connected, the contact distance between the first detection pins 24 and the female connector 22 will be less than the contact distance between the first functional pins 23 and the female connector 22. This unique distance setting lays the foundation for accurate subsequent testing of the connector's connection status.

[0059] The female connector 22 also has several second functional pins 25 (for cooperating with several first functional pins 23). Among these second functional pins 25, two second functional pins 25 corresponding to the first detection pins 24 on the male connector 21 are specifically designated as second detection pins 26. Furthermore, these two second detection pins 26 are respectively connected to a low level or a high level, thereby providing a clear level reference for the detection process.

[0060] The motherboard 1 has two detection ports 3 (gpio1 and gpio2 ports as shown in the figure), which are connected to the two first detection pins 24 on the male connector 21 respectively. Specifically, when a test is required, one detection port 3 is connected to one of the first detection pins 24, and the other detection port 3 is connected to the other first detection pin 24, thus forming a complete detection circuit path.

[0061] During the testing process, the motherboard 1 monitors and compares the voltage levels of the first detection pin 24 and the second detection pin 26 in real time. When the motherboard 1 detects that the voltage levels of the first detection pin 24 and the second detection pin 26 are completely consistent, it can be determined that the connection between the male connector 21 and the female connector 22 is normal. Conversely, when the motherboard 1 detects that the voltage levels of the first detection pin 24 and the second detection pin 26 are inconsistent, it indicates that the connection between the male connector 21 and the female connector 22 is abnormal, i.e., a floating voltage phenomenon has occurred.

[0062] The connector testing system provided in this embodiment of the invention achieves rapid and accurate judgment of the connector connection status by carefully setting a first detection pin 24 and a second detection pin 26 on the male connector 21 and the female connector 22 respectively, and cleverly utilizing the detection port 3 on the motherboard 1 to monitor the consistency of the voltage levels of these two detection pins. Compared with traditional manual visual inspection, this testing method effectively overcomes the drawbacks of strong subjectivity and low efficiency in manual inspection. Manual visual inspection often relies on the experience and subjective judgment of the inspector, and is easily affected by factors such as fatigue and ambient light, resulting in inaccurate and unstable test results. The testing system of this invention completely avoids these problems and can complete the testing task in an objective and automated manner.

[0063] Meanwhile, compared with infrared detection equipment, the detection system of this invention also has significant advantages. Infrared detection equipment has certain limitations in terms of recognition accuracy and may be affected by environmental factors, thus affecting the accuracy of the detection results. This invention, however, by directly monitoring the voltage level of the detection pins, can more accurately determine the connection status of the connector, effectively improving the accuracy and stability of the detection results.

[0064] By accurately detecting the connection status of connectors, the detection system of this invention can promptly identify connector malfunctions and take corresponding measures to address them, thereby effectively reducing electronic device failures caused by poor connector connections. This is of great significance for improving the overall performance and lifespan of electronic devices. In the production, assembly, and quality control processes of electronic devices, the detection system of this invention provides an efficient and reliable detection method that ensures that every connector is in a good connection state, thus guaranteeing the quality and reliability of electronic devices and providing strong support for the healthy development of the electronic device industry.

[0065] Please refer to this again. Figure 3-4 In one embodiment of this invention, the two first detection pins 24 are arranged diagonally opposite each other; at the same time, the two second detection pins 26 are also arranged diagonally opposite each other.

[0066] It's important to note that the diagonal placement of the two detection pins is a deliberate design choice, primarily aimed at maximizing the reliability and accuracy of the detection. In real-world connector applications, connection status can become locally abnormal due to various factors. The diagonal pin layout offers a unique advantage, covering the entire diagonal of the connector. This layout effectively avoids misjudgments caused by poor contact at one end of the connector. Specifically, if poor contact only occurs at one end of the connector, a non-diagonal pin placement might lead the detection system to incorrect connection status judgments due to normal contact at the other end. A diagonal placement, however, provides a more comprehensive view of the overall connector connection, ensuring the detection system accurately determines the true connection status and provides a reliable basis for subsequent troubleshooting and resolution.

[0067] Understandably, in Figure 5 The diagram illustrates a diagonal setup with the bottom left and top right corners, where the two first detection pins 24 are b1 and c1, and the two second detection pins 26 are b and c. However, in practical applications, this diagonal setup is not the only option. In fact, a diagonal setup with the top left and bottom right corners can also be used, such as... Figure 6 As shown, the two first detection pins 24 are a1 and d1, and the two second detection pins 26 are a and d. Both of these diagonal settings can effectively detect the connector connection status to a certain extent.

[0068] Furthermore, from the perspective of rigorous testing, to further improve the accuracy and reliability of the test results, the bottom left and top right corners, and the top left and bottom right corners, can be tested simultaneously. Figure 7As shown. In this case, motherboard 1 only needs to add two corresponding detection ports 3. By simultaneously monitoring two sets of diagonal detection pins, the connection status of the connector can be comprehensively judged from multiple dimensions, further reducing the possibility of misjudgment and providing a more solid guarantee for the stable operation of electronic devices.

[0069] It should be further explained that, in Figure 3 , Figure 5 , Figure 6 as well as Figure 7 In the diagram, the first detection foot 24 is drawn and illustrated as a foot with a relatively short length. The sole purpose of this approach is to make it easier and clearer to distinguish it from other normal first functional feet 23 in the diagram from the perspective of visual presentation, thereby facilitating a more intuitive understanding of the relevant structures and component relationships.

[0070] However, it is important to emphasize that in practice, the length of the first detection pin 24 is exactly the same as the length of the normal first functional pin 23; they are completely identical in terms of this physical property. The only difference between the two lies solely in the height of the metal contact.

[0071] In one embodiment of this invention, there are specific design requirements for the contact distance between the first detection pin 24 and the female connector 22. Specifically, the contact distance between the first detection pin 24 and the female connector 22 is set to be less than or equal to 0.12 mm. Figure 2 As shown.

[0072] During the actual assembly and use of the connector, the connection status between the first detection pin 24 and the female connector 22 is crucial. When the distance between the first detection pin 24 and the female connector 22 (specifically, the second detection pin 26) is less than or equal to 0.12mm, a stable and reliable electrical connection can be confirmed between them. This allows the detection system to accurately obtain the voltage level information of the first detection pin 24, thereby providing an accurate basis for judging the overall connection status of the connector.

[0073] However, if an abnormality occurs during connector assembly, causing the distance between the first detection pin 24 and the female connector 22 to exceed the aforementioned acceptable contact distance range (i.e., greater than 0.12 mm), it indicates a floating phenomenon. Once floating occurs, a good electrical connection cannot be formed between the first detection pin 24 and the female connector 22, potentially leading to increased contact resistance, unstable signal transmission, or even interruption. This not only affects the accuracy of the detection system's judgment of the connector connection status but may also have a serious negative impact on the performance and stability of the entire electronic device, causing malfunctions such as data transmission errors and abnormal device operation.

[0074] Understandably, this precise contact distance design helps improve the sensitivity and accuracy of detection. When there is a slight, inconspicuous rise in the connection between the male connector 21 and the female connector 22, the distance between the first detection pin 24 and the female connector 22 may exceed 0.12mm, thus causing differences in the voltage level. The detection port 3 on the main board 1 can accurately determine whether the connector connection is normal, effectively avoiding misjudgments caused by poor but not obvious contact.

[0075] Therefore, strictly controlling the contact distance between the first detection pin 24 and the female connector 22 to be less than or equal to 0.12mm is an important measure to ensure the normal operation of the connector testing system and improve the reliability of electronic equipment. Of course, considering the diverse needs of different customers, this contact distance can also be adjusted according to specific circumstances to better meet the personalized requirements of customers.

[0076] In one embodiment of this example, the low level is set to GND (i.e., ground level), while the high level is set to 1.8V.

[0077] From a technical principle perspective, setting the low level as GND has multiple rationales and necessities. In electronic circuit systems, GND serves as a common reference point, providing a stable zero-potential reference for the entire circuit. In connector testing scenarios, using GND as the low level ensures that the testing circuit has a unified and reliable reference standard. When the first detection pin 24 and the second detection pin 26 are in good contact, the detection port 3 on the motherboard 1 can accurately detect the low-level signal, thus providing a clear and definite basis for judging the connector's connection status. Moreover, GND as a low level has wide versatility and stability, existing in almost all electronic device circuits. This allows the testing system to be easily integrated and adapted with various electronic devices without requiring additional complex circuit design to construct a low-level reference.

[0078] Setting the high-level voltage to 1.8V was also a carefully considered decision. 1.8V is a commonly used voltage value in electronic devices, and many integrated circuits and electronic components can operate stably at this voltage level. Choosing 1.8V as the high-level voltage ensures a sufficient level difference during detection, allowing detection port 3 to clearly distinguish between high and low level signals, effectively improving detection accuracy and reliability. When the first detection pin 24 contacts the second detection pin 26 connected to the 1.8V high-level voltage, detection port 3 can sensitively detect changes in the high-level signal, thus accurately determining the connector's connection status. Furthermore, the relatively low voltage of 1.8V, while ensuring detection functionality, reduces power consumption and heat generation in the circuit, contributing to improved energy efficiency and stability of the entire detection system and extending the lifespan of the electronic equipment.

[0079] In summary, in this embodiment, setting the low level to GND and the high level to 1.8V is the result of comprehensive consideration of various factors such as technical principles and practical application requirements, and is of vital importance to ensuring the performance and stability of the connector testing system.

[0080] In one specific embodiment presented in this example, the connector testing system further expands its functional architecture, encompassing at least one of the following functional modules. These modules work collaboratively, greatly enhancing the overall performance and practicality of the testing system:

[0081] (1) Alarm module:

[0082] The alarm module is connected to the motherboard 1, forming a tight signal interaction link. During the detection process, the motherboard 1 continuously monitors and compares the voltage levels of the first detection pin 24 and the second detection pin 26 of different connectors. Once the motherboard 1 detects an inconsistency between the voltage levels of the first detection pin 24 and the second detection pin 26, indicating an abnormality in the connection between the corresponding male connector 21 and female connector 22, the alarm module will immediately respond and issue an alarm signal. For example, the alarm signal can take various forms, including but not limited to audible alarms and / or visual alarms. Audible alarms can attract the operator's attention through sounds of different frequencies, tones, or rhythms; visual alarms can intuitively convey abnormal information through flashing, color changes, etc. This dual alarm mechanism ensures that operators can promptly detect connector connection abnormalities in various working environments and scenarios, thereby quickly taking corresponding measures to prevent further escalation of equipment failures caused by connection problems.

[0083] (2) Recording module:

[0084] The recording module is also connected to the motherboard 1, and its recording function is activated synchronously when the motherboard 1 performs testing. As the motherboard 1 sequentially tests the connection status of the male connector 21 and female connector 22 of several connectors, the recording module accurately records the relevant test data. This data covers key information such as the number of normal connections and the number of abnormal connections. Through long-term accumulation and analysis of this data, a deeper understanding of the overall connection quality of the same batch of connectors can be obtained, providing strong data support for subsequent process improvements, quality control, and equipment maintenance. For example, statistical analysis of the number of abnormal connections can identify problems that connectors are prone to encounter in specific production batches or under specific usage conditions, allowing for targeted adjustments to production processes or strengthened equipment maintenance.

[0085] (3) Communication module:

[0086] The communication module connects to motherboard 1, establishing a data transmission bridge between the testing system and external devices. During testing on motherboard 1, the communication module transmits the connection status testing data of male connector 21 and female connector 22 to external devices in real time. These external devices can be servers in a remote monitoring center, data analysis terminals, etc. Through this remote data transmission function, remote monitoring and data analysis of the connector testing status are achieved. Personnel do not need to be physically present at the testing site to obtain testing data in real time through external devices and promptly grasp the connector's operating status. Simultaneously, by using data analysis tools to deeply mine and analyze large amounts of testing data, potential quality problems and performance trends can be discovered, providing a scientific basis for enterprise production decisions, quality control, and product optimization.

[0087] (4) Display module:

[0088] The display module connects to the motherboard 1 and displays the connection status test data of the male connector 21 and female connector 22 in real time and intuitively when the motherboard 1 performs a test task. Test personnel can quickly understand the connection status of the connectors simply by observing the display module, without the need for complex data interpretation and analysis. The display module can use common display technologies such as LCD or OLED displays to present test data in a clear and easy-to-read manner, such as connection status indicator lights, specific data values, and charts. This intuitive display method greatly improves the efficiency and convenience of the test work, reduces the workload and error probability of test personnel, and ensures the accuracy and timeliness of the test results.

[0089] In summary, the connector testing system in this embodiment integrates functional modules such as an alarm module, a recording module, a communication module, and a display module, forming a complete and high-performance testing system that can meet the diverse needs of connector testing in different scenarios.

[0090] Although this application frequently uses terms such as motherboard, male connector, and female connector, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0091] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
