[0002] With the increasing prosperity of technologies such as cloud computing, big data, artificial intelligence, and the Internet, the normal operation of all power equipment depends on power supply. In the context of modern scientific and technological development, power supply and safety have become important concerns. As a device for managing power distribution, the intelligent power distribution unit (PDU) plays a vital role. However, due to long-term use or inactivity, the plug may become loose, and it is impossible to detect whether there is any looseness between the plug and the PDU socket; this may lead to serious consequences such as power outages and fires, resulting in greater losses. Summary of the invention

[0003] In order to solve the technical problem that the prior art cannot detect whether there is looseness between the plug and the PDU socket, which leads to serious consequences such as power outage and fire, resulting in great losses, the purpose of the present invention is to provide an intelligent PDU with loose plug alarm, and the technical solution adopted is as follows: An embodiment of the present invention provides an intelligent PDU with a loose plug alarm, the intelligent PDU with a loose plug alarm comprising: a socket module, a switch module, and an alarm buzzer; wherein: The first end of the switch module is connected to the positive pole of the socket module, and the second end of the switch module is in contact with the side wall of the positive pole of the socket module; the second end of the switch module is connected to the first end of the alarm buzzer, and the second end of the alarm buzzer is connected to the negative pole of the socket module; Wherein, the socket module remains powered on, and when the power plug in the socket module is in a loose state, the switch module and the alarm buzzer form a loop, and the alarm buzzer sounds an alarm.

[0004] In some possible implementations, the socket module includes: a socket spring and a socket grounding spring; wherein, The positive pole of the socket reed is connected to the first end of the switch module, the negative pole of the socket reed is connected to the second end of the alarm buzzer, and the socket grounding reed is connected to the grounding end.

[0005] In some possible implementations, the switch module includes: a first switch unit and a second switch unit; wherein: The first switch unit is connected to the positive pole of the socket reed in the socket module, and the second switch unit is in contact with the side wall of the positive pole of the socket reed in the socket module.

[0006] In some possible implementations, the smart PDU with loose plug alarm further includes: an insulating pad; The insulating pad is arranged on one side of the upper portion of the second switch unit, and the insulating pad is in contact with the side wall of the positive electrode of the socket spring.

[0007] In some possible implementations, the first switch unit includes: a first spring sheet or a first micro switch; the second switch unit includes: a second spring sheet and a second micro switch.

[0008] In some possible implementations, the smart PDU with loose plug alarm further includes: a connection plate; The lower portion of the connection plate is connected to or disconnected from the first switch unit, and the upper portion of the connection plate is connected to or disconnected from the second switch unit.

[0009] In some possible implementations, when the power plug is in the loose state, the first switch unit and the lower part of the connecting plate are overlapped and conductive; there is no contact and no conductivity between the upper part of the connecting plate and the upper part of the second switch unit, and the second switch unit is connected to the first end of the alarm buzzer, the second end of the alarm buzzer is connected to the negative pole of the socket module, there is no contact and no conductivity between the connecting plate and the second switch unit, and the alarm buzzer enters the disconnected state.

[0010] In some possible implementations, when the power plug is fully inserted into the socket, the power plug drives the insulating pad and causes the upper elastic arm of the second switch unit to move, so that the second switch unit is connected to the upper part of the connecting plate, and the pin of the power plug presses down the first switch unit to disconnect the first switch unit from the connecting plate, and the alarm buzzer enters the disconnected state.

[0011] In some possible implementations, when the power plug is not fully inserted into the socket and the electrical equipment corresponding to the power plug is turned on, the power plug drives the insulating pad and drives the upper elastic arm of the second switch unit to move, so that the second switch unit is connected to the upper part of the connecting plate, and the pin of the power plug does not press down the first switch unit, so that the first switch unit and the connecting plate remain overlapped and turned on, and the alarm buzzer enters the turned-on state.

[0012] In some possible implementations, when the power plug is loose and has detached from the socket reed in the socket module, the side wall of the power plug drives the insulating pad to move the elastic arm on the upper part of the second switch unit, so that the second switch unit contacts and conducts with the upper part of the connecting plate, and the pin of the power plug does not press down the first switch unit, so that the first switch unit remains overlapped and conducted with the connecting plate, and the alarm buzzer enters the conducting state.

[0013] The embodiment of the present invention has the following beneficial effects: in the intelligent PDU, by connecting the first end of the switch module to the positive pole of the socket module, the second end of the switch module is kept in contact with the side wall of the positive pole of the socket module, so that the switch module can remain powered on. And the second end of the switch module is connected to the first end of the alarm buzzer, and the second end of the alarm buzzer is connected to the negative pole of the socket module; in this way, when the power plug in the socket module is in a loose state, the switch module and the alarm buzzer form a loop, and the alarm buzzer alarms. In this way, by setting the socket module, the switch module and the alarm buzzer in the intelligent PDU, the loose plug can be detected in time, and for the loose plug, the buzzer issues an alarm to reduce the occurrence of power interruption and the like, thereby improving the safety of the equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0019] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0020] The following is a detailed description of a specific solution of a smart PDU with a loose plug alarm provided by the present invention in conjunction with the accompanying drawings. Figure 1 , which shows a schematic diagram of the composition structure of an intelligent PDU with loose plug alarm provided by an embodiment of the present invention, the intelligent PDU 100 includes: a socket module 101, a switch module 102, and an alarm buzzer 103; wherein: The first end of the switch module 102 is connected to the positive electrode of the socket module 101, and the second end of the switch module 102 is in contact with the side wall of the positive electrode of the socket module 101; the second end of the switch module 102 is connected to the first end of the alarm buzzer 103, and the second end of the alarm buzzer 103 is connected to the negative electrode of the socket module; Wherein, the socket module remains powered on, and when the power plug in the socket module is in a loose state, the switch module and the alarm buzzer form a loop, and the alarm buzzer sounds an alarm.

[0021] Here, the switch module 102 includes: a first switch unit and a second switch unit, and the first switch unit and the second switch unit can be springs or micro switches. That is, the first switch unit includes: a first spring or a first micro switch; the second switch unit includes: a second spring and a second micro switch. Figure 2 As shown, the first switch unit is a first spring 21, and the second switch unit is a second spring 22; the switch module 102 may also include Figure 2 The connecting plate 32 is shown.

[0022] In some possible implementations, such as Figure 2 As shown, the socket module 102 includes: a socket reed 201, a socket grounding reed 202 and a socket lower shell 203; wherein the positive pole of the socket reed 201 is connected to the first end of the switch module 102, the negative pole of the socket reed 201 is connected to the second end of the alarm buzzer 103, and the socket grounding reed 202 is connected to the ground end.

[0023] Here, the first spring 21 serves as the first end of the switch module, and the second spring 22 serves as the second end of the switch module; the positive pole of the socket spring 201 serves as the positive pole of the socket module, and the negative pole of the socket spring 201 serves as the negative pole of the socket module; in this way, the first spring is connected to the positive pole of the socket spring 201, the second spring is in contact with the side wall of the positive pole of the socket spring 201, the second spring is connected to the first end of the alarm buzzer (for example, the tail end of the second spring is connected to the alarm buzzer through a wire), and the second end of the alarm buzzer is connected to the negative pole of the socket spring 201. In this way, the socket is always powered on, and when the power plug is not inserted into the socket, the first spring and the second spring do not contact, and the second spring is always connected to the alarm buzzer, so the alarm buzzer cannot form a loop, that is, the alarm buzzer does not alarm.

[0024] In some possible implementations, such as Figure 3 As shown, the smart PDU with loose head alarm also includes: an insulating pad 31 and a connecting plate 32; the insulating pad 31 is arranged on one side of the upper part of the second switch unit, and the insulating pad 31 keeps contact with the side wall of the positive pole of the socket spring. The lower part of the connecting plate 32 is connected or disconnected with the first switch unit, and the upper part of the connecting plate 32 is connected or disconnected with the second switch unit. For example, the lower part of the connecting plate overlaps or disconnects with the first spring sheet, and the upper part of the connecting plate contacts or does not contact with the second spring sheet.

[0025] In some possible implementations, the socket module always remains powered, and when the power plug is in the loose state, the first switch unit and the lower part of the connecting plate are overlapped and conductive; there is no contact and no conductivity between the upper part of the connecting plate and the upper part of the second switch unit, and the second switch unit is connected to the first end of the alarm buzzer, the second end of the alarm buzzer is connected to the negative pole of the socket module, there is no contact and no conductivity between the connecting plate and the second switch unit, and the alarm buzzer enters the disconnected state.

[0026] Here, the loose state of the power plug may be that the power plug is not inserted into the socket, such as Figure 3 As shown, the first spring sheet and the lower part of the connecting plate 32 are overlapped and conductive, the upper part of the connecting plate 32 and the elastic arm of the upper part of the second spring sheet have no contact and are not conductive, and the second spring sheet is always connected to the alarm buzzer, and the other terminal of the alarm buzzer is always connected to the negative pole socket reed. Because the connecting plate and the second spring sheet have no contact and are not conductive, the alarm buzzer does not alarm.

[0027] In some possible implementations, when the power plug is fully inserted into the socket, the power plug drives the insulating pad and causes the upper elastic arm of the second switch unit to move, so that the second switch unit is connected to the upper part of the connecting plate, and the pin of the power plug presses down the first switch unit to disconnect the first switch unit from the connecting plate, and the alarm buzzer enters the disconnected state.

[0028] Here, the socket always remains powered. When the power plug is fully inserted into the socket, the side wall of the plug blade drives the insulating pad and drives the upper elastic arm of the second spring sheet to move so that it is connected to the upper part of the connecting plate. The plug pin presses down the first spring sheet to disconnect the first spring sheet from the connecting plate. In this way, the alarm buzzer cannot form a circuit, so the buzzer does not alarm.

[0029] In some possible implementations, when the power plug is not fully inserted into the socket and the electrical equipment corresponding to the power plug is turned on, the power plug drives the insulating pad and drives the upper elastic arm of the second switch unit to move, so that the second switch unit is connected to the upper part of the connecting plate, and the pin of the power plug does not press down the first switch unit, so that the first switch unit and the connecting plate remain overlapped and turned on, and the alarm buzzer enters the turned-on state.

[0030] Here, when the plug of the power-taking device is not inserted into place (but the power-consuming device is powered on at this time), the side wall of the plug drives the insulating pad, and the insulating pad drives the upper elastic arm of the second spring sheet to move so that the second spring sheet contacts and conducts with the upper part of the connecting plate; when the plug is not pressed down or the first spring sheet is not in place when pressed down, the first spring sheet remains overlapped and conducted with the connecting plate, and the alarm buzzer forms a loop, and the alarm buzzer starts to alarm.

[0031] In some possible implementations, when the power plug is loose and has detached from the socket reed in the socket module, the side wall of the power plug drives the insulating pad to move the elastic arm on the upper part of the second switch unit, so that the second switch unit contacts and conducts with the upper part of the connecting plate, and the pin of the power plug does not press down the first switch unit, so that the first switch unit remains overlapped and conducted with the connecting plate, and the alarm buzzer enters the conducting state.

[0032] Here, when the plug of the power-taking device is loose and the power-consuming device is still powered on (wherein, when the plug of the power-taking device continues to loosen upward and causes the power of the power device to be cut off, the plug has been separated from the socket spring), the side wall of the plug insert drives the insulating pad, and the insulating pad drives the upper elastic arm of the second spring sheet to move so that the second spring sheet contacts and conducts with the upper part of the connecting plate. When the plug insert is not pressed down or the first spring sheet is not in place when pressed down, the spring sheet and the connecting plate remain overlapped and conducted, and the alarm buzzer forms a loop, at which time the alarm buzzer starts to alarm.

[0033] When a person inserts a plug into a socket, and the electrical equipment is powered on and within a certain height range before the plug is fully seated, the buzzer is in the on state and alarms. At this time, because someone is operating, the alarm buzzer of this socket can eliminate the abnormality. Among them, the height distance of the plug not in place or the plug is loose can be adjusted within a certain range.

[0034] In the embodiment of the present invention, the alarm of each group of power supply sockets of the socket is set independently, and the power supply end of the buzzer is respectively connected to the positive and negative poles of the reed in a group of sockets. The positive and negative poles can complete the detection and alarm functions, and the grounding end does not need to be detected. In this way, the alarm is triggered by whether the plug is inserted into the bottom of the socket, so as to check whether the plug and the PDU are loose, and an alarm is triggered for the loose plug; thus, for large Internet Data Center (IDC) computer rooms, it can effectively help engineers discover the hidden dangers of PUD in advance, prevent equipment power outages, short circuits or fires, effectively reduce risks, and reduce economic losses.
