[0042] As described in the background section, leakage detection devices in related technologies have a problem with detection blind spots. The inventors have discovered that this problem occurs because the leakage detection device includes multiple leakage detection strips, which are connected to each other via connectors. While the leakage detection strips can be used for leakage detection, the area where the connectors are located cannot detect leakage in a timely and effective manner. This results in a detection blind spot in the leakage detection device, increasing the risk of damage to electrical equipment or important data.

[0043] To address the aforementioned technical problems, this application provides a connector and a leakage detection device. By providing a first leakage detection strip in the inner cavity of the housing and a connecting hole on the housing, the first leakage detection strip is used to detect whether liquid enters the housing through the connecting hole. The leakage detection device can detect whether leakage has occurred at the location of the connector in a timely and accurate manner, thereby avoiding blind spots in the leakage detection device and reducing the risk of damage to electrical equipment or important data.

[0044] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0045] Please refer to the attached document. Figure 1 This application provides a leak detection device 1000, which is typically installed on the ground in public places, such as data centers, server rooms, museums, or archives. If a liquid leak occurs in the aforementioned important locations, the leak detection device 1000 provided in this embodiment can detect the leak in a timely and effective manner and can alert staff to handle the situation promptly.

[0046] The leakage detection device 1000 includes multiple second leakage detection strips 200 and connectors 100. The connectors 100 are disposed between any two adjacent second leakage detection strips 200 and are connected to the adjacent second leakage detection strips 200 respectively. That is, a connector 100 is provided between each adjacent second leakage detection strip 200 to extend the length of the leakage detection device 1000 and extend the detection range of the leakage detection device 1000 as much as possible.

[0047] Please refer to the attached document. Figure 2The connector 100 includes a housing 110, a first leakage detection strip 120, and a connecting hole 130. The housing 110 serves as the supporting body for the first leakage detection strip 120, providing a carrier for its installation. Exemplarily, the first leakage detection strip 120 is disposed within the inner cavity of the housing 110, for example, by adhesive bonding or insertion.

[0048] The housing 110 also serves as a connecting component for connection to the second leak detection strip 200. For example, both ends of the housing 110 are respectively connected to the second leak detection strip 200 to achieve connection between adjacent second leak detection strips 200. In some examples, the first leak detection strip 120 and the second leak detection strip 200 are also interconnected.

[0049] A connecting hole 130 is provided on the housing 110, connecting the outer side of the housing 110 with the inner cavity of the housing 110. In this way, leaked liquid can enter the inner cavity of the housing 110 through the connecting hole 130 and be detected by the first leak detection band 120.

[0050] Both the second leak detection strip 200 and the first leak detection strip 120 typically include a substrate, a conductive layer, and an insulating layer. The conductive layer can be disposed on top of the substrate or embedded within the substrate, and the insulating layer can cover the conductive layer to protect it. The substrate serves as the supporting structure for the leak detection strip and is typically made of a flexible, wear-resistant, and corrosion-resistant material (e.g., polyester, polyvinyl chloride, etc.).

[0051] When the area where the leak detection device 1000 is located has a leak (e.g., condensate, liquid coolant, or water), the leak seeps into the second leak detection strip 200. These liquids may act as a conductive medium and come into direct contact with the conductive material in the second leak detection strip 200, thereby forming one or more conductive paths and changing the resistance value of the second leak detection strip 200.

[0052] It is important to understand that reference Figure 5 As shown, in this embodiment, the leak detection device 1000 also includes a sensor 300. The sensor 300 can be directly integrated inside the second leak detection strip 200, or it can be a separate component connected to the second leak detection strip 200 via a connecting wire. Thus, when liquid leaks and comes into contact with the second leak detection strip, the sensor detects the change in resistance and converts this signal into a recognizable electrical or digital signal, enabling workers to detect leaks promptly.

[0053] Please refer to the attached document. Figure 5The leakage detection device 1000 may further include an alarm 400 and a controller 500. The controller 500 may be connected to both the alarm 400 and the sensor 300. The controller 500 may control the alarm 400 to issue an alarm notification based on the detection signal from the sensor 300. The alarm 400 may be an audible alarm, a visual alarm, or an audible and visual alarm.

[0054] This alarm mechanism significantly shortens the time interval between the occurrence and detection of a leak, helping to reduce damage and loss caused by liquid leaks. In particular, in important locations such as data centers, server rooms, museums, and archives, liquid leaks can lead to serious consequences such as equipment damage, data loss, and damage to artwork or documents. The instant alarm function of the Leak Detection Device 1000 helps staff take timely measures to prevent the situation from escalating and improve the overall safety of these locations.

[0055] Please refer to the attached document. Figure 3 and attached Figure 4 In this embodiment, the connector 100 is provided with a communication hole 130 that communicates with the inner cavity of the housing 110, and a first leakage detection band 120 is provided in the inner cavity of the housing 110. The first leakage detection band 120 is used to detect whether liquid enters the inner cavity of the housing 110 through the communication hole, so as to detect whether leakage occurs at the location of the connector 100 in a timely and accurate manner, thereby avoiding the existence of detection blind spots in the leakage detection device and reducing the risk of damage to electrical equipment or important data.

[0056] At the same time, the first leakage detection band 120 works in conjunction with the second leakage detection band 200, so that the leakage detection device 1000 has dual detection. In this way, whether there is leakage in the area where the housing 110 is located or in other areas, the leakage detection device 1000 can be detected in a timely and accurate manner, thereby avoiding the existence of blind spots in the leakage detection device 1000 and further reducing the risk of damage to electrical equipment or important data.

[0057] In one possible implementation, the housing 110 includes a side plate 111 and a top plate 112, which are interconnected, for example, the top plate 112 is connected to the top of the side plate 111. It should be understood that the top plate 112 and the side plate 111 can be fixedly connected, or they can be connected in other ways. Exemplarily, the top plate 112 and the side plate 111 can be detachably connected, for example, by snap-fit ​​connection; or by plug-in connection; or by screws securing the top plate 112 and the side plate 111. This configuration allows users or maintenance personnel to easily disassemble and reassemble the housing 110, making it more convenient and efficient for replacing damaged parts, cleaning the internal space, or performing upgrades, thereby reducing maintenance costs and difficulty.

[0058] Furthermore, the detachable top panel 112 design makes the housing 110 more flexible and convenient during assembly, and also facilitates transportation and storage. During transportation, the top panel 112 can be separated from the side panels 111 to reduce packaging volume and weight, thereby lowering transportation costs. It also saves more space during storage.

[0059] In this embodiment, the top plate 112 and the side plate 111 can be made of the same material or different materials. For example, the side plate 111 is made of metal or stainless steel, such as SUS304 stainless steel; the top plate 112 is made of transparent and detachable acrylic material. This ensures the structural strength of the connector 100 and also facilitates the inspection of the connector 100 and the subsequent replacement of the first leakage detection strip 120 and internal handling after leakage.

[0060] The connecting hole 130 is provided at least on the side plate 111. In other words, in one example, the connecting hole 130 is provided on the side plate 111 and extends through the side plate 111 along its thickness direction. In another example, the connecting hole 130 is provided on both the side plate 111 and the top plate 112.

[0061] It should be recognized that the connecting hole 130 can be flexibly set according to actual needs to adapt to different installation environments. For example, in situations where leakage detection from multiple directions is required, connecting holes 130 can be set on both the side plate 111 and the top plate 112 to improve the comprehensiveness and accuracy of the leakage detection device 1000.

[0062] The shape of the connecting hole 130 can be a regular shape. For example, in some examples, the connecting hole 130 is provided on both the side plate 111 and the top plate 112. In this case, the shape of the connecting hole 130 on the side plate 111 can be the same as or different from the shape of the connecting hole 130 on the top plate 112. For example, the shape of the connecting hole 130 on the side plate 111 is rectangular, and the shape of the connecting hole 130 on the top plate 112 can be circular or elliptical.

[0063] Furthermore, the number of connecting holes 130 can be one or more. For example, the connector 100 has a plurality of connecting holes 130, which are at least spaced apart on the side plate 111.

[0064] It should be understood that when multiple through holes 130 are simultaneously provided on the top plate 112 and the side plate 111, some through holes 130 are provided on the top plate 112 and some through holes 130 are provided on the side plate 111.

[0065] With this configuration, the distribution of multiple connecting holes 130 can cover a wider area, thereby increasing the likelihood of detecting leaks. This makes leak detection more comprehensive and accurate, enabling timely detection and handling of potential leaks and preventing further damage or safety accidents.

[0066] In addition, the through hole 130 can also serve as a ventilation hole. Multiple ventilation holes can more effectively promote the circulation of air or liquid, thereby enhancing the heat exchange between the inside and outside of the housing, helping to reduce the internal temperature of the housing, and improving the overall operating efficiency and stability of the equipment.

[0067] In one possible implementation, it can be specifically combined with Figure 3 As shown, the side panel 111 includes a first side panel 1111 and a second side panel 1112 disposed opposite to each other, with the top ends of both the first side panel 1111 and the second side panel 1112 connected to the top panel 112. A connecting hole 130 is provided on the first side panel 1111 and / or the second side panel 1112. In one example, the connecting hole 130 is provided on one of the first side panel 1111 and the second side panel 1112. In another example, the connecting hole 130 is provided on both the first side panel 1111 and the second side panel 1112. This arrangement increases the flexibility of the layout of the connecting hole 130 on the side panel 111.

[0068] In one possible implementation, the connector 100 has a plurality of first leakage detection bands 120, each of which extends from one end of the housing 110 to the other end of the housing 110, and the plurality of first leakage detection bands 120 are spaced apart in a direction perpendicular to the extension of the first leakage detection bands 120.

[0069] It should be understood that one end and the other end of the housing 110 can refer to the two ends of the housing 110 in its extending direction. For example, the extending direction of each first leakage detection strip 120 is perpendicular to the first side plate 1111 and points towards the second side plate 1112. In other words, a plurality of first leakage detection strips 120 are spaced apart along the width direction of the housing 110; each first leakage detection strip 120 extends along the length direction of the housing 110.

[0070] In this way, the number of first leakage detection bands 120 can be increased, which can achieve a wider coverage of the interior area of ​​the housing 110. Even if leakage occurs at different locations of the housing 110, it can be detected in time by at least one first leakage detection band 120, thereby improving the comprehensiveness and accuracy of the detection by the first leakage detection band 120.

[0071] Furthermore, multiple first leak detection strips 120 can improve the reliability and stability of the leak detection device 1000 to a certain extent. Even if one first leak detection strip 120 fails or malfunctions, the other first leak detection strips 120 can still work normally, ensuring that the entire leak detection device 1000 can operate continuously and stably, thereby improving the safety of the location where the leak detection device 1000 is located.

[0072] In one possible implementation, continue to refer to Figure 2 As shown, the housing 110 also includes a base plate 113, wherein the base plate 113 includes a main body segment and inclined segments connected to both ends of the main body segment, and the angle between the surface of the inclined segments and the surface of the main body segment is an obtuse angle. In some examples, the main body segment is parallel to the ground, and the distance between the upper surface of the inclined segment away from the ground and the ground gradually decreases along the direction away from the main body segment, or in other words, the upper surface of the inclined segment gradually approaches the ground along the direction away from the main body segment.

[0073] The first leak detection strip 120 is laid on the main body section of the base plate 113, and the end of the second leak detection strip 200 is laid on the inclined section of the base plate 113 and extends onto the main body section. Thus, the inclined section acts as a transition section, allowing the second leak detection strip 200 to transition naturally when laid to the edge of the base plate, avoiding direct impact or scratches that might occur at right-angle edges. This significantly reduces the risk of wear and damage to the leak detection strip during long-term use, extending its service life.

[0074] Furthermore, during use, the connector 100 is easily crushed or damaged by personnel, trolleys, or heavy objects. If the side of the base plate 113 is perpendicular to the ground, it is very likely that the second leakage detection strip 200 will separate from the connector 100, or even break. Therefore, in this embodiment, the second leakage detection strip 200 can transition naturally when laid to the edge of the base plate, so that the second leakage detection strip 200 is completely attached to the ground. This can avoid the formation of a height difference between the connection point of the second leakage detection strip 200 and the connector 100 and the rest of the second leakage detection strip 200, reducing or even avoiding the risk of the second leakage detection strip 200 breaking.

[0075] It should be noted that the second leakage detection strip 200 located on the main body section can be connected to the main body section by adhesive bonding or other methods.

[0076] For example, refer to Figure 2 As shown, a sharp portion 140 is provided in the area of ​​the main body section near the inclined section, and the sharp portion 140 extends in the direction toward the top plate 112; the sharp portion 140 is used to fix the second leakage detection strip 200 and the first leakage detection strip 120. For example, the second leakage detection strip 200 and the first leakage detection strip 120 are stacked sequentially on the main body section and pass through the sharp portion 140.

[0077] With this configuration, the pointed part 140 extends in the direction toward the top plate 112, providing a more stable fixing point for the second leakage detection strip 200 and the first leakage detection strip 120. This ensures that the second leakage detection strip 200 and the first leakage detection strip 120 are not easily loosened or detached when subjected to external force or vibration, thereby improving the stability and reliability of the entire leakage detection device 1000.

[0078] In this embodiment, the housing 110 further includes a side plate 111 and a top plate 112, with the side plate 111 connecting the bottom plate 113 and the top plate 112. Alternatively, the bottom plate 113 is connected to the side of the side plate 111 opposite to the top plate 112. The bottom plate 113 and the side plate 111 can be made of the same material, and the bottom plate 113 and the side plate 111 can be a single piece or separate pieces.

[0079] In one possible implementation, the housing 110 further includes a cover 150 that covers the end of the bottom plate 113. Exemplarily, in the length direction, the lengths of the side plates 111 and the top plate 112 are both less than the length of the bottom plate 113; for example, the lengths of the side plates 111 and the top plate 112 are less than the length of the main body segment. In this case, the cover 150 covers the area of ​​the bottom plate 113 extending relative to the side plates 111 and the top plate 112. Alternatively, the cover 150 may be rotatably connected to the top plate 112 and cover the end of the bottom plate 113.

[0080] In an optional configuration, a first engaging portion 114 is provided on the inclined section of the base plate 113, and a second engaging portion adapted to the first engaging portion 114 is provided on the cover 150; when the cover 150 is closed on the base plate 113, the first engaging portion 114 and the second engaging portion are engaged and connected. One of the first engaging portion 114 and the second engaging portion is an engaging groove, and the other is an engaging protrusion.

[0081] In this embodiment, the portion of the second leakage detection band 200 located at the engagement position engages between the first engagement portion 114 and the second engagement portion. This arrangement, through the engagement connection between the first engagement portion 114 on the inclined section and the second engagement portion on the cap 150, complements the sharp portion 140, achieving double fixation of the second leakage detection band 200 and improving the connection stability of the second leakage detection band 200.

[0082] It should be understood that the shape of the housing 110 can be chosen in several ways. In one example, the shape of the housing 110 can be linear. In another example, please refer to the appendix. Figure 4 The housing 110 includes a first housing 115 and a second housing 116. The first housing 115 is connected to the second housing 116, and the inner cavities of the first housing 115 and the second housing 116 are interconnected. A preset angle exists between the first housing 115 and the second housing 116. This preset angle can be an acute angle, a right angle, or an obtuse angle, etc. This design allows for flexible adaptation to the needs of various applications, especially in spaces with corners or irregular shapes. This design greatly increases the application range and applicability of the leakage detection device 1000, eliminating the need for complex modifications or customizations to adapt to different site shapes.

[0083] Furthermore, by precisely matching the shape and layout of the application site, the leak detection device 1000 can more accurately cover potential leak areas, reducing the possibility of missed detections or false alarms.

[0084] In summary, the connector and leakage detection device provided in this application embodiment, by providing a first leakage detection strip in the connector housing and providing a connecting hole on the housing, the connecting hole can connect the outside of the housing and the inner cavity of the housing; the first leakage detection strip is used to detect whether liquid enters the housing through the connecting hole, thereby timely and accurately detecting whether leakage has occurred at the location of the connector, thus avoiding the existence of detection blind spots in the leakage detection device and reducing the risk of damage to electrical equipment or important data.
