Description

Technical Field

[0001] This invention belongs to the field of power supply terminal technology, specifically relating to a power supply terminal, a power supply terminal abnormality detection device and method. Background Technology

[0002] With the rapid development of IT information technology, the deployment and application of server systems are also increasing. As the number of servers gradually increases, the power supply stability of the server power supply, as the core power supply unit for normal server operation, is receiving more and more attention from the market and users. Whether the power cord is properly inserted into the power input terminal is the most basic guarantee for ensuring stable power supply.

[0003] However, the relevant technologies only detect whether the power cord is properly inserted into the power input terminal by adding an input voltage detection circuit. This can only detect cases where the power cord is loose or not inserted. It cannot detect cases where the power cord is not reliably inserted but power is still supplied. As a result, when the server is running in the actual data center, poor contact can easily occur due to server vibration or slight collision with the power cord, which in turn affects the operation of the equipment behind the power cord and causes losses. Summary of the Invention

[0004] In view of the above problems, embodiments of this application provide a power supply terminal, a power supply terminal abnormality detection device and method, so as to overcome the above problems or at least partially solve the above problems.

[0005] In a first aspect, this application provides a power supply terminal, including: a first contact, a second contact, and a female terminal;

[0006] Wherein, the first end of the first contact is partially or entirely located inside the plastic shell of the female terminal, and the second end of the first contact is connected to the target part of the female terminal;

[0007] The first end of the second contact is disposed opposite to the first end of the first contact, and the second end of the second contact is connected to the test module; wherein, when the first end of the first contact is not compressed, there is a gap between the first contact and the second contact;

[0008] When the male terminal is inserted into the female terminal, the male terminal presses the first end of the first contact member into contact with the first end of the second contact member, so that a detection circuit is formed between the test module and the target component.

[0009] Specifically, when the detection loop is formed between the test module and the target component, the test pin of the test module outputs a first-level signal; when the detection loop is not formed between the test module and the target component, the test pin of the test module outputs a second-level signal; the first-level signal is different from the second-level signal.

[0010] Optionally, the first contact includes: a first sub-contact and a second sub-contact; wherein the second sub-contact is located in the inner wall of the plastic shell of the female terminal;

[0011] The end of the first sub-contact is located outside the inner wall of the plastic shell, the tail of the first sub-contact penetrates the inner wall of the plastic shell and connects with the end of the second sub-contact, and the tail of the second sub-contact is connected to the target part.

[0012] Optionally, the inner wall of the plastic shell is provided with a groove; the end of the first sub-contact is provided with a first protruding contact; wherein, the protruding length of the first protruding contact is greater than or equal to the depth of the groove, and the protruding cross-sectional size is less than or equal to the cross-sectional size of the groove.

[0013] Optionally, the inner wall of the plastic shell is provided with a groove, and the first end of the second contact member is provided with a second protruding contact, and the second protruding contact is fixed in the groove;

[0014] The first sub-contact has a third protruding contact at its end; wherein the superimposed length of the protrusion of the second protruding contact and the third protruding contact is greater than or equal to the groove depth.

[0015] Optionally, the first end of the second contact member is provided with a fourth protruding contact, wherein the fourth protruding contact protrudes from the inner wall of the plastic shell, and the protrusion height is less than a preset height.

[0016] Optionally, the target component is a grounding plate.

[0017] Optionally, the grounding piece is a grounding wire insert or a conductive shielding piece; wherein the conductive shielding piece is attached to the inner wall of the plastic shell of the female terminal.

[0018] Optionally, the first level signal is a low level signal, and the second level signal is a high level signal.

[0019] In a second aspect of this application, a power supply terminal abnormality detection device is provided, which is applied to the power supply terminal described in the first embodiment of this application, and a test module connected to the second contact in the power supply terminal;

[0020] A signal generator is connected in parallel on the signal transmission line between the second contact and the test module; wherein...

[0021] The signal generator is used to output a second-level signal to the test module;

[0022] The test module is used to receive the second level signal. When the male terminal is inserted into the female terminal to form a detection loop, the test pin of the test module outputs the first level signal; when the detection loop is not formed, the test pin of the test module outputs the second level signal.

[0023] Optionally, the device further includes: an alarm indicator light, which is connected to a test pin of the test module;

[0024] The alarm indicator light is used to issue an alarm message in response to the second level signal output by the test pin.

[0025] A third aspect of the present invention provides a method for detecting power supply terminal anomalies, applied to the power supply terminal anomaly detection device described in Embodiment 2 of this application, the method comprising:

[0026] When the male connector is inserted into the female connector and the power supply to the female connector is energized, the level state of the test pin of the test module is obtained.

[0027] When the level state is characterized as a first level signal, it is determined that the male terminal is reliably inserted into the female terminal;

[0028] When the level state is characterized as a second level signal, it is determined that the male terminal is not reliably inserted into the female terminal.

[0029] The power supply terminal provided in this application includes: a first contact, a second contact, and a female terminal; wherein, a portion or all of the first end of the first contact is located within the plastic shell of the female terminal, and the second end of the first contact is connected to the target component of the female terminal; the first end of the second contact is disposed opposite to the first end of the first contact, and the second end of the second contact is connected to a test module; wherein, when the first end of the first contact is not compressed, there is a gap between the first contact and the second contact; when the male terminal is inserted into the female terminal, the male terminal compresses the first end of the first contact and the first end of the second contact to form a detection circuit between the test module and the target component; wherein, when a detection circuit is formed between the test module and the target component, the test pin of the test module outputs a first level signal, and when a detection circuit is not formed between the test module and the target component, the test pin of the test module outputs a second level signal; the first level signal is different from the second level signal.

[0030] The power supply terminal provided in this application embodiment is used to determine whether the power supply cable (male terminal) of a power source is reliably inserted. The power supply terminal includes a first contact, a second contact, and a female terminal. When the first end of the first contact is not compressed, there is a gap between the first contact and the second contact. The first end of the first contact is partially or entirely located within the plastic shell of the female terminal. The second end of the first contact is connected to the target component of the female terminal. The first end of the second contact is opposite to the first end of the first contact, and the second end of the second contact is connected to the test module.

[0031] Therefore, when the male terminal is inserted into the female terminal, the male terminal will only press the first end of the first contact and the second contact to form a detection circuit when the male terminal is reliably inserted into the female terminal. Only when the detection circuit is formed will the test pin of the test module output a first level signal. When the male terminal is not reliably inserted into the female terminal, the test pin of the test module will output a second level signal. Since the first level signal and the second level signal are different, the level state of the test pin of the test module can be used to determine whether the male terminal is reliably inserted into the female terminal. This facilitates accurate identification of situations where the power cord, which is integrated with the male terminal, is not properly inserted, improves the reliability of the power supply, and prevents poor contact or power loss due to server vibration or slight collision with the power cord, thereby affecting the reliable power supply to the equipment behind the power cord and ensuring a stable power supply to the power source where the female terminal is located.

Detailed Implementation

[0050] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0051] Reference Figure 1 , Figure 1 This is a structural diagram of a power supply terminal provided by related technologies. The power supply terminal in the diagram is a standard AC power supply terminal (model C14 or C20, etc.) currently used in the industry or market. Although the standard terminal is designed with insertion and extraction force requirements and corresponding friction anti-slip design, if it is not reliably connected to the power cord, there is still a probability of it falling off, or the failure to identify the faulty connection will lead to a decrease in the reliability of the power supply in the later stage.

[0052] The relevant technology for checking whether the power cord is connected to the power supply terminal generally involves adding an input voltage detection circuit at the power supply point. When the power cord is disconnected or not inserted into the power supply terminal, the system detects the loss of input voltage and reports an input alarm. When the power cord is not fully inserted but there is still power, the input voltage detection is still normal, so there is no input loss alarm.

[0053] However, during the testing process, there are two main issues. First, input voltage loss doesn't necessarily mean the power cord is plugged in incorrectly; it could also be due to a genuine power supply malfunction at the front end. Therefore, there isn't a one-to-one correlation between input voltage loss and power cord plugging problems. Second, when the power cord isn't fully plugged in, there might be contact, but vibration or slight impact can easily cause poor contact, which the current solution cannot identify. In actual server operation in a data center, input voltage anomalies caused by improperly plugged-in power cords pose difficulties for maintenance and problem analysis personnel. They cannot effectively determine the root cause of the problem, and they cannot detect and nip problems in the bud during early use, thus increasing the overall probability of server malfunctions or alarms.

[0054] Therefore, regarding the above-mentioned problem, it is still impossible to effectively identify whether the power cord and the power supply terminal are properly connected. Therefore, this application provides a power supply terminal to solve the above-mentioned problem. Please refer to the embodiment for details.

[0055] Reference Figure 2 , Figure 2This is a front view of the external structure of a power supply terminal provided in an embodiment of this application. As can be seen from the figure, the power supply terminal includes: a first contact 1, a second contact 2, and a female terminal 3. The first end 111 of the first contact 1 is partially or entirely located within the plastic shell of the female terminal 3, and the second end 122 of the first contact 1 is connected to the target component 5 of the female terminal 3. The first end 21 of the second contact 2 is disposed opposite to the first end 111 of the first contact 1, and the second end 122 of the second contact 2 is connected to the test module 6. The first end 111 of the first contact 1 is not subjected to compression. When pressed, there is a gap between the first contact 1 and the second contact 2; when the male terminal 4 is inserted into the female terminal 3, the male terminal 4 presses the first end 111 of the first contact 1 into contact with the first end 21 of the second contact 2, so that a detection circuit is formed between the test module 6 and the target component 5; wherein, when a detection circuit is formed between the test module 6 and the target component 5, the test pin of the test module 6 outputs a first level signal, and when a detection circuit is not formed between the test module 6 and the target component 5, the test pin of the test module 6 outputs a second level signal; the first level signal is different from the second level signal.

[0056] The target component is a part of the female terminal structure. Generally, a female terminal consists of an insulator and a non-insulator. The insulator is usually a plastic shell, and the non-insulator is a connector used for power transmission, a screw fixing the connector to the plastic shell, or some other non-insulator in the female terminal that performs other functions. The target component in this application is a non-insulator in the female terminal structure, which is a structure that can be used to transmit signals. The connectors in the female terminal structure include grounding connectors, live wire connectors, and neutral wire connectors; the target component can be any one of the grounding connector, live wire connector, and neutral wire connectors, or a screw or a non-insulator.

[0057] In this embodiment, the female terminal 3 can correspond to the power supply terminal provided by related technologies. The first contact 1 is a conductive metal component or cable, and the second contact 2 is made of the same material as the first contact 1. The metal component is generally made of beryllium copper or stainless steel. (Refer to...) Figure 3 and Figure 4 , Figure 3 This is a front view of the internal structure of a power supply terminal provided in an embodiment of this application; Figure 4 This is a side view of the internal structure of a power supply terminal provided in an embodiment of this application. Figure 4 As can be seen from this, the first end 111 of the first contact 1 is partially located inside the plastic shell of the female terminal 3. Figure 3 As can be seen from this, the second end 122 of the first contact 1 is connected to the target part 5 of the female terminal 3. Figure 3Target component 5 in the text can refer to the grounding wire insert inside the female terminal, but this is just an example and does not mean that target component 5 uniquely corresponds to the grounding wire insert. It can also be the live wire insert or the neutral wire insert, or other suitable non-insulating parts in the female terminal. See further... Figure 4 The first end 21 of the second contact 2 is disposed opposite to the first end 111 of the first contact 1, and there is a gap between the first contact 1 and the second contact 2 when the first end 111 of the first contact 1 is not squeezed. This also indicates that when the female terminal 3 is not in contact with the male terminal 4 and the first end 111 of the first contact 1 is not squeezed by the male terminal 4, the first contact 1 and the second contact 2 are not in contact.

[0058] Reference Figure 5 and Figure 6 , Figure 5 This is a schematic diagram illustrating the reliable insertion and removal of a male connector into a power supply terminal, as provided in an embodiment of this application. Figure 6 This is a schematic diagram illustrating a scenario where the male connector 4 is not reliably inserted into the power supply terminal, as provided in an embodiment of this application. When the male connector 4 is inserted into the female connector 3, two situations exist: one is that the male connector 4 is reliably inserted into the female connector 3, and the other is that the male connector 4 is not reliably inserted into the female connector 3. (Refer to...) Figure 5 When the male terminal 4 is reliably inserted into the female terminal 3, the male terminal 4 will press the first end 111 of the first contact 1 into contact with the first end 21 of the second contact 2. Since the second end 122 of the second contact 2 is connected to the test module 6, the first contact 1 and the second contact 2 can be regarded as a wire, which conducts the circuit between the test module 6 and the target 5, thereby forming a detection circuit between the test module 6 and the target 5.

[0059] Test module 6 can be a test circuit that detects if the male connector 4 is not reliably inserted into the female connector 3. In this case, test module 6 will detect that a detection loop has been formed between it and the target component 5. At this point, test module 6 will output a first-level signal, which is the level state corresponding to the detection loop formed between test module 6 and the target component 5. (Refer to...) Figure 6 When the male terminal 4 is not reliably inserted into the female terminal 3, specifically, the first end 111 of the first contact 1 may not be pressed, or the first end 111 of the first contact 1 may be pressed but not deep enough to press the first end 111 of the first contact 1 into contact with the first end 21 of the second contact 2, thus failing to form a detection loop between the test module 6 and the target component 5. In this case, to inform the staff of this information and to proceed with the next step as needed, the test module 6 will also output a second-level signal to indicate the current insertion status of the male terminal 4.

[0060] To accurately distinguish between reliable insertion of the male connector into the female connector and unreliable insertion, a first-level signal corresponds to reliable insertion, and a second-level signal corresponds to unreliable insertion. Therefore, the first and second-level signals are two different signals used to inform relevant personnel whether the male connector is reliably inserted. Specifically, the difference may lie in the level state or the numerical value of the level; this embodiment does not limit this to specific cases.

[0061] The following example illustrates this: when the target component is a grounding plug, if the test module 6 and the grounding plug form a detection circuit, the first level signal output by the test pin of the test module will only be zero, i.e., a low level state. In order to distinguish the low level signal, the second level signal cannot be zero. It can be a level signal with an output of 5V, which is a high level signal state compared to zero.

[0062] Furthermore, when the target component is neither a grounding plug nor any other grounded non-insulated component, assuming that the first level signal output when the target component forms a detection circuit with the test module 6 is a 3V signal, then in order to distinguish the first level signal, the second level signal will not be 3V, but can be 5V, 12V, 0V, etc. This application does not make any specific limitations.

[0063] With the power supply terminal provided in this application embodiment, when the male terminal 4 is inserted into the female terminal 3, the male terminal 4 will only press the first end 111 of the first contact 1 and the first end 21 of the second contact 2 to form a detection circuit when the male terminal 4 is reliably inserted into the female terminal 3. Only when the detection circuit is formed will the test pin of the test module 6 output a first level signal. When the male terminal 4 is not reliably inserted into the female terminal 3, the test pin of the test module 6 will output a second level signal. Since the first level signal and the second level signal are different, the level state of the test pin of the test module 6 can be used to determine whether the male terminal 4 is reliably inserted into the power supply terminal. This facilitates effective identification of whether the power cord integrated with the male terminal 4 is not properly inserted, improves the reliability of the power supply, and prevents poor contact or power loss due to server vibration or slight collision with the power cord, thereby affecting the reliable power supply to the equipment behind the power cord and ensuring the stable power supply of the power supply where the female terminal 3 is located.

[0064] In one embodiment, the first contact 1 includes a first sub-contact 11 and a second sub-contact 12; wherein the second sub-contact 12 is located in the inner wall of the plastic shell of the female terminal 3; the end 111 of the first sub-contact 11 is located outside the inner wall of the plastic shell, the end 122 of the first sub-contact 11 penetrates the inner wall of the plastic shell and is connected to the end 121 of the second sub-contact 12, and the end 122 of the second sub-contact 12 is connected to the target component 5.

[0065] In this embodiment, refer to Figure 7 , Figure 7 This is a schematic diagram of a three-dimensional structure of a power supply terminal provided in an embodiment of this application. The first contact 1 includes a first sub-contact 11 and a second sub-contact 12. The second sub-contact 12 is located within the inner wall of the plastic shell of the female terminal 3. The end 111 of the first sub-contact 11 is located outside the inner wall of the plastic shell, and the tail 122 of the first sub-contact 11 penetrates the inner wall of the plastic shell and connects with the end 121 of the second sub-contact 12. The tail 122 of the second sub-contact 12 is connected to the target component 5. For ease of connection... Figure 7 The connection method is to sleeve it around the target part 5. The end 122 of the second sub-contact 12 is a rectangular metal piece with a central opening. In order to ensure the reliability of the connection between the second contact 2 and the target part 5, the second sub-contact 12 in the figure is located inside the plastic shell of the female terminal 3. This embodiment does not limit the shape of the second sub-contact 12 or the connection method between the second sub-contact 12 and the target part 5, as long as the second sub-contact 12 and the target part 5 are reliably connected.

[0066] In one embodiment, the inner wall of the plastic shell is provided with a groove 31; the end 111 of the first sub-contact 11 is provided with a first protruding contact 1111; wherein, the protruding length of the first protruding contact 1111 is greater than or equal to the depth of the groove 31, and the protruding cross-sectional size is less than or equal to the cross-sectional size of the groove 31.

[0067] In this embodiment, refer to Figure 8 , Figure 8This is a schematic diagram of the positions of the first contact and the second contact provided in the first embodiment of this application. In order to ensure smooth insertion and removal of the male terminal 4 and reduce the obstruction of insertion and removal of the male terminal 4, a groove 31 can be provided on the inner side wall of the plastic shell. The end 111 of the first sub-contact 11 is provided with a first protruding contact 1111. The first end 21 of the second contact 2 is in the groove 31. In order to ensure that when the male terminal 4 is inserted into the female terminal 3, the first end 111 of the first contact 1 and the first end 21 of the second contact 2 are reliably contacted, the protruding length of the first protruding contact 1111 is greater than or equal to the depth of the groove 31, and the protruding cross-sectional size of the first protruding contact 1111 is less than or equal to the cross-sectional size of the groove 31. In this way, when the male terminal 4 can be reliably inserted into the female terminal 3, the test module 6 and the target part 5 form a detection circuit.

[0068] In one embodiment, the inner wall of the plastic shell is provided with a groove 31, the first end 21 of the second contact member 2 is provided with a second protruding contact 211, and the second protruding contact 211 is fixed in the groove 31; the end 111 of the first sub-contact member 11 is provided with a third protruding contact 1112; wherein, the protruding superposition length of the second protruding contact 211 and the third protruding contact 1112 is greater than or equal to the depth of the groove 31.

[0069] In this embodiment, refer to Figure 9 , Figure 9 This is a schematic diagram of the positions of the second type of first contact and second contact provided in the embodiments of this application; a groove 31 is provided on the inner sidewall of the plastic shell, a second protruding contact 211 is provided on the first end 21 of the second contact 2, and the second protruding contact 211 is located in the groove 31, and a third protruding contact 112 is provided on the end 111 of the first sub-contact 11. Then the protruding superimposed length of the second protruding contact 211 and the third protruding contact 1112 is greater than or equal to the depth of the groove 31.

[0070] if Figure 7 and Figure 8 If the groove 31 in the first contact is the same, then the protruding length of the third protruding contact 1112 will be less than the protruding length of the first protruding contact 1111.

[0071] In one embodiment, the first end 21 of the second contact member 2 is provided with a fourth protruding contact 212, wherein the fourth protruding contact 212 protrudes from the inner sidewall of the plastic shell and the protrusion height is less than a preset height.

[0072] In this embodiment, refer to Figure 10 , Figure 10This is a schematic diagram of the positions of the first contact and the second contact provided in the third embodiment of this application; the first end 21 of the second contact 2 is provided with a fourth protruding contact 212, and the fourth protruding contact 212 protrudes from the inner wall of the plastic shell. Then, the end 111 of the first sub-contact 11 does not need to be provided with a protruding contact. As long as it can be ensured that when the male terminal 4 is reliably inserted into the female terminal 3, the end 111 of the first sub-contact 11 contacts the first end 21 of the second contact 2. In order to ensure the smooth insertion and removal of the male terminal 4, the protrusion height of the fourth protruding contact 212 needs to be less than the preset height. Assuming that when the male terminal 4 is inserted into the female terminal 3, the distance between it and the inner wall of the plastic shell is 1mm, and the end 111 of the first sub-contact 11 is 0.5mm, then it is necessary to reasonably set the preset height of the fourth protruding contact 212 by combining the material of the inner wall of the plastic shell, the material of the first sub-contact 11, the material of the fourth protruding contact 212, and their own characteristics.

[0073] In one embodiment, the target element 5 is a grounding plate.

[0074] In this embodiment, the target component 5 can be a grounding plate. This is to use the original structure of the female terminal 3 itself as the target component 5 while making as few modifications as possible to the power supply terminal provided by the relevant technology, i.e., the female terminal 3. When the target component 5 is a grounding plate, a simple test circuit can be designed to detect whether the male terminal 4 can be reliably inserted into the female terminal 3.

[0075] In one embodiment, the grounding piece is a grounding wire insert or a conductive shielding piece; wherein the conductive shielding piece is attached to the inner wall of the plastic shell of the female terminal 3.

[0076] In this embodiment, the female terminal 3 generally has a grounding wire plug. This grounding wire plug is to ensure that the electrical equipment can be properly grounded. When the equipment malfunctions and causes leakage, the grounding wire can conduct the current to the ground, protecting the user from electric shock. Therefore, the grounding plug can be a grounding wire plug. Alternatively, it can be a conductive shielding plate. During the power supply process, there will be electromagnetic interference. In order to minimize the impact of electromagnetic interference on the equipment, a conductive shielding plate is generally attached to the inner wall of the plastic shell of the female terminal 3. Since the conductive shielding plate is also a grounded conductive shielding plate, the grounding plate can also be a conductive shielding plate.

[0077] In one embodiment, the first level signal is a low level signal, and the second level signal is a high level signal.

[0078] In this embodiment, when the male terminal 4 is reliably inserted into the female terminal 3, and the first end 111 of the first contact 1 contacts the first end 21 of the second contact 2, the test module 6 will form a detection circuit with the target component 5. At this time, since the target component 5 is a grounding piece, the test module 6 is equivalent to being connected to ground, and the test pin of the test module 6 is in a low-level state. Therefore, the first level signal can be a low-level signal. Since the first level signal and the second level signal are different, the second level signal can be a high-level signal at this time.

[0079] For example, the following will combine Figure 5 and Figure 6 This application provides a detailed explanation of the process for ensuring reliable insertion of a male terminal into a female terminal, specifically regarding the power supply terminal provided in this application.

[0080] Firstly, from Figure 5 As can be seen, the male terminal 4 is reliably inserted into the female terminal 3, and the male terminal 44 does not squeeze the first end 111 of the first contact 1 and the first end 21 of the second contact 2 into contact. At this time, the first contact 1 and the second contact 2 will act as a wire to conduct the connection between the test module 6 and the target component 5. Then the information on the target component 5 can be known. If the target component 5 is a grounding plug, then a detection loop will be formed between the test module 6 and the target component 5.

[0081] Then from Figure 6 As can be seen, the male terminal 4 is not reliably inserted into the female terminal 3. A portion of the male terminal 4 has entered the female terminal 3, but because the male terminal 4 has not pressed the first end 111 of the first contact 1 into contact with the first end 21 of the second contact 2, although the male terminal 4 has been inserted into the female terminal 3, the insertion depth is insufficient, and the first end 111 of the first contact 1 cannot make contact with the first end 21 of the second contact 2, thus the insertion is not reliable. This could lead to vibration on the female terminal 3 side, or some external cause, causing the power cord on the male terminal 4 side to be touched. In this case, the male terminal 4 may detach from the female terminal 3, and the electrical energy from the female terminal 3 side cannot be stably transmitted to the electrical equipment connected to the power cord of the male terminal 4.

[0082] Finally, by detecting whether a detection loop is formed between the test module 6 and the target component 5, it can be determined whether the male terminal 4 can be reliably inserted into the female terminal 3. In combination with some external circuit settings, corresponding information can be sent to notify relevant personnel to take the next step.

[0083] Based on the same inventive concept, and referring to Figure 11 , Figure 11This is a schematic diagram of a power supply terminal abnormality detection device provided in an embodiment of this application; applied to a power supply terminal in Embodiment 1, and a test module 6 connected to the second contact 2 in the power supply terminal; wherein, a signal generator 7 is connected in parallel on the signal transmission line between the second contact 2 and the test module 6; wherein, the signal generator 7 is used to output a second level signal to the test module 6; the test module 6 is used to receive the second level signal, and when the male terminal 4 is inserted into the female terminal 3 to form a detection loop, the test pin of the test module 6 outputs a first level signal; when the detection loop is not formed, the test pin of the test module 6 outputs the second level signal.

[0084] In this embodiment, refer to Figure 12 , Figure 12 This is a topology diagram of a power supply terminal abnormality detection device provided in an embodiment of this application. Figure 12 As can be seen, a signal generator 7 is connected in parallel on the signal transmission line between the second contact 2 and the test module 6. This signal generator 7 can be an external signal generating device, or it can be a second-level signal output from a certain output port of the chip in the test module 6. This second-level signal is different from the first-level signal, and it always acts on the test pin of the test module 6. Figure 12 The signal generator 7 in the test module is P3V3. P3V3 refers to a high-level voltage of 3.3V applied to the test pin. The PSU (Power Supply Unit) is the power supply, which contains a DSP (Digital Signal Processing) chip. A server is connected to the PSU and can communicate with the power supply chip to understand the power supply status and whether the male power connector is reliably inserted into the female connector terminal. When the male connector 4 is not reliably inserted into the female connector 3, that is, the first end 111 of the first contact 1 and the first end 21 of the second contact 2 are not in contact, the signal transmission line between the second contact 2 and the test module 6 is in a floating state. Therefore, the test module 6 and the target 5 do not form a detection loop, and the test pin of the test module 6 outputs the second level signal.

[0085] When the male terminal 4 is reliably inserted into the female terminal 3, that is, when the first end 111 of the first contact 1 is in contact with the first end 21 of the second contact 2, a detection circuit will be formed between the test module 6 and the target component 5. Assuming that the target component 5 is a grounding piece and the second level signal is a high level signal, then the first level signal output by the test pin of the test module 6 will be a low level signal, which proves that the male terminal 4 is reliably inserted into the female terminal 3.

[0086] In one embodiment, the device further includes an alarm indicator light 8, which is connected to a test pin of the test module 6; wherein the alarm indicator light 8 is used to issue an alarm message in response to the second level signal output by the test pin.

[0087] In this embodiment, the power supply terminal abnormality detection device can be installed on the server's power supply unit, or it can be connected to the server's power supply unit via other communication lines. (Refer to...) Figure 11 The power supply terminal abnormality detection device also includes an alarm indicator light 8. This alarm indicator light 8 is connected to the test pin of the test module 6 and is used to respond to the second-level signal output by the test pin. The alarm indicator light 8 can be an LED, and can be defined to emit a specific LED color or flashing frequency as an alarm message when the second-level signal is received. Relevant personnel can then directly determine if the power cord insertion is abnormal by observing the LED color or flashing frequency, i.e., if the male terminal 4 is not reliably inserted into the female terminal 3. Based on the alarm information, they can then take the next step according to actual needs.

[0088] In addition to the alarm indicator, an oscilloscope can be connected to the test pins of test module 6. The oscilloscope display can show the corresponding values ​​of the output level signals of the test pins. By defining the voltage values ​​corresponding to the first level signal and the second level signal respectively, the value displayed on the oscilloscope can be used to determine whether the male terminal is reliably inserted into the female terminal. Then, the relevant personnel can take the next step based on the voltage value displayed on the oscilloscope.

[0089] Based on the same inventive concept, and referring to Figure 13 , Figure 13 This is a flowchart illustrating the steps of a power supply terminal anomaly detection method provided in this application embodiment, applied to the power supply terminal anomaly detection device in Embodiment 2. The method steps include:

[0090] Step S131: When the male terminal is inserted into the female terminal and the power supply of the female terminal is energized, obtain the level state of the test pin of the test module.

[0091] In this embodiment, when the male terminal is inserted into the female terminal and the power supply to the female terminal is energized, the level state of the test pin of the test module is obtained. The level state of the test pin of the test module can be obtained by whether the alarm indicator light issues an alarm message, or by connecting the level signal output by the test pin of the test module to an oscilloscope.

[0092] Step S132: When the level state is characterized as a first level signal, determine that the male terminal is reliably inserted into the female terminal.

[0093] In this embodiment, if the alarm indicator light is used to obtain the signal, then after the male connector is inserted into the female connector, observe whether the alarm indicator light emits an alarm message. If not, this indicates that the level is the first level signal, confirming that the male connector is reliably inserted into the female connector. If the alarm indicator light is used to obtain the signal, then the value corresponding to the first level signal displayed on the oscilloscope can be used to confirm that the male connector is reliably inserted into the female connector.

[0094] Step S133: When the level state is characterized as a second level signal, it is determined that the male terminal is not reliably inserted into the female terminal.

[0095] In this embodiment, if the alarm indicator light is used to obtain the signal, then after the male connector is inserted into the female connector, observe whether the alarm indicator light emits an alarm message. If an alarm message is emitted, it indicates that the voltage level is the second voltage level signal, confirming that the male connector is not reliably inserted into the female connector. If the alarm indicator light is used to obtain the signal, then the value corresponding to the second voltage level signal displayed on the oscilloscope can be used to determine that the male connector is not reliably inserted into the female connector. At this time, the data center maintenance personnel can re-insert and re-insert the male connector until the voltage level represents the first voltage level signal.

[0096] For example, the following will be based on Figure 12 Taking the topology diagram of the provided power supply terminal anomaly detection device as an example, the provided power supply terminal is... Figure 7 The power supply terminal shown has a grounding connector as the target component. The test module connected to the second contact in the power supply terminal is a power supply chip. One pin of this power supply chip is connected to the power supply terminal as a test pin. A signal generator (P3V3) that releases a high-level signal is also connected in parallel on the connection line between the test pin and the power supply terminal. The other pin of the power supply chip is connected to the server, facilitating the transmission of the level signal output from the test pin to the system. This allows the system to determine the power supply status of the power chip and, in conjunction with... Figure 13 This section will explain the alarm process for abnormal power cord insertion or detachment, referring to... Figure 14 , Figure 14 This is a flowchart illustrating a power cord insertion or detachment abnormality alarm provided in an embodiment of this application. The male terminal is part of the power cord; specifically, inserting the power cord into the female terminal involves inserting the male terminal of the power cord into the female terminal.

[0097] Step S141: Insert the power cord into the power supply terminal. This step simply involves inserting the male connector into the female connector. After confirming insertion, proceed to step S142.

[0098] Step S142: Determine the power cord insertion status and whether it is inserted correctly; that is, check whether the test module and the grounding pin form a detection loop. If yes, proceed to step S143. If no, it indicates that the power cord is not inserted correctly, and proceed to step S144.

[0099] Step S143: No abnormal alarm, no need to re-plug, end. At this time, other actions can also be performed depending on whether the system has power.

[0100] Step S144: An abnormal alarm occurs, requiring re-plugging and unplugging. Proceed to step S141. At this point, it can be determined whether the power cord is not fully inserted or not inserted at all, based on whether the system has power. In addition, the abnormal alarm can also be transmitted to the system through the communication interface. After seeing the alarm, the user or maintenance personnel should promptly resolve the power cord insertion problem (re-plugging and unplugging, or continuing to insert until the contacts are made and the alarm disappears).
