Description

Technical Field

[0001] The present application relates to energy box testing technology, and in particular to a grounding connection device and an energy box testing system. Background Art

[0002] Before the energy box is installed to form the energy collection device, the parameters of the energy box need to be tested. During some parameter tests, such as the output power parameter test, the energy box needs to be grounded. In the related art, a wire clamp is used to connect the energy box to the ground pin, but the wire clamp has the problem of unstable clamping during the clamping process, resulting in poor contact. Poor contact may cause the electrical equipment to be unable to be reliably grounded, increasing the risk of electric shock and electrical fire. It may also cause the equipment to malfunction during operation due to unstable potential, affecting the normal operation of the equipment and the accuracy of the test data.

[0003] To improve grounding reliability, the common solution is to modify the wire clamp, such as by modifying its material and clamping strength to enhance its stability and prevent poor contact. However, even after modification, the clamp may still become unstable when subjected to external forces, leading to poor contact, and the improvement is therefore not significant.

[0039] In order to make the purpose, technical solutions and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0041] Unless otherwise defined, all technical and scientific terms used in the embodiments of the present application have the same meanings as those commonly understood by those skilled in the art. The terms used in the embodiments of the present application are only for the purpose of describing the embodiments of the present application and are not intended to limit the present application.

[0042] Before further describing the embodiments of the present application in detail, the nouns and terms involved in the embodiments of the present application are explained. The nouns and terms involved in the embodiments of the present application are subject to the following interpretations.

[0043] 1) Energy harvesting box: A device that collects energy from the environment and converts it into electricity for use by electronic devices. It is commonly used in wireless sensor networks, remote monitoring systems, and IoT devices, particularly in locations where battery replacement or power supply maintenance is difficult. Its core function is to achieve autonomous energy harvesting, reducing or eliminating reliance on external power sources.

[0044] 2) Grounding connection device: A type of device used in electrical systems to connect the metal parts of equipment or facilities to the grounding body (such as grounding rods, grounding grids, etc.).

[0045] 3) Wire clamp: A commonly used electrical connection device used to fix and connect wires to ensure reliable connection of the circuit.

[0046] 4) Grounding: An important step in electrical engineering that involves connecting a part of an electrical system or the entire system to the ground potential to ensure safe operation and prevent electrical faults.

[0047] 5) Ground Pin: A specific pin on an electronic device or circuit board that is used to connect the device or circuit to the ground or earth to provide a reference level and ensure safety.

[0048] Before the energy collection box is installed to form the energy collection device, the parameters of the energy collection box need to be tested. For example, when performing the output power parameter test, the energy collection box needs to be grounded. In the related art, a wire clamp is used to connect the energy collection box to the ground pin for grounding. However, the wire clamp is prone to unstable clamping during the clamping process, resulting in poor contact. In addition, from the perspective of the wire, each time the wire clamp is clamped, the wire will be pulled, causing a certain amount of loss to the wire. After multiple operations, it is easy to cause poor contact due to wire loss. In addition, during the actual grounding process, the operator can easily neglect and forget the clamping operation, resulting in a failure of the grounding process and a safety hazard.

[0049] Since the cause of the above-mentioned problem is the poor contact caused by the unstable clamping of the wire clamp, on this basis, in order to improve the reliability of the grounding process, the solution that technicians in this field can usually think of is to modify the wire clamp and avoid the problem of poor contact by reinforcing and stabilizing the wire clamp. Or, from the perspective of the wire, the loss of the wire can be reduced by strengthening the quality of the wire, thereby avoiding poor contact. However, there are limitations to solving this technical problem from the perspective of the wire clamp or the wire. It can only modify the clamping method of the wire clamp or the wire itself on the basis of retaining the wire clamp. It has low scalability and cannot solve the problem that the operator is prone to neglect and forget to clamp the wire clamp.

[0050] Therefore, to simultaneously address multiple issues, including unstable clamping, poor conductive contact, and operator negligence and forgetfulness, the present invention breaks with conventional thinking, abandoning the existing approach of using a clamp to connect the energy harvesting box to the grounding pin and fundamentally transforming the implementation of grounding. The present invention provides a grounding connection device and energy harvesting box testing system. During actual grounding, the energy harvesting box can be grounded by simply placing the metal energy harvesting box on the grounding connection device. This eliminates the need for a clamp, eliminating the risk of unstable clamping. During the entire grounding process, the wires are not moved or repeatedly disconnected and connected, preventing additional wire wear even with repeated use, thus avoiding the problem of poor wire contact. Furthermore, the grounding connection device can serve as a workbench for grounding the energy harvesting box. The operator simply places the energy harvesting box on the grounding connection device to achieve grounding. Compared to the prior art method of clamping the energy harvesting box with a clamp, placing the energy harvesting box on the grounding connection device is more invasive and easily noticeable, making it less likely for the operator to miss this step. Therefore, through the grounding connection device and energy box testing system provided in the embodiments of the present application, a new grounding processing method is proposed, which can improve the convenience and reliability of grounding processing of the energy box to be tested.

[0051] The following will be combined Figures 1 to 4 , illustrating the exemplary application and implementation of the ground connection device provided in the embodiments of the present application.

[0052] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a grounding connection device provided in an embodiment of the present application. The grounding connection device provided in an embodiment of the present application is used to cooperate with a metal box to be tested to ground the energy acquisition box. The grounding connection device includes: an insulating support structure 101, a conductive plate 102, and a wire 103. The insulating support structure 101 is used to support the conductive plate 102, so that the conductive plate 102 is suspended; the conductive plate 102 is used to place the energy acquisition box to be tested and is in contact with the metal box of the energy acquisition box to be tested; and a wire 103 is provided at one end of the conductive plate 102 for connecting to a ground lead.

[0053] In some embodiments, the insulating support structure includes at least two support rods, and the at least two support rods form a hollow area; a conductive plate covers the hollow area and is fixedly connected to the support rods, and the conductive plate is used to place the energy box to be tested and can be at least partially fitted with the metal box body; the wire is electrically connected to the conductive plate, and the wire is used to connect the ground lead.

[0054] Here, the support rod is made of an electrically insulating material that can prevent the passage of electric current, such as wood, rubber, or plastic. In the embodiment of the present application, the support rod is set to wood as an example. The hollow area is a three-dimensional space, and the wire is electrically connected to either end of the conductive plate. The conductive plate and the support rod can be connected by bundling with a wire harness, or they can be fixed by sticking with an adhesive material. The wire can be directly welded to the conductive plate, or the wire can be fixed to the conductive plate by a spring clip or a clamp.

[0055] In some embodiments, the conductive plate is rectangular or square, and two opposite ends of the conductive plate are respectively fixed to two support rods.

[0056] In some embodiments, at least four holes are provided on the conductive plate, and a wiring harness is passed through the holes provided on the conductive plate and bundled onto the support rod, so that the conductive plate and the support rod are fixedly connected.

[0057] In some embodiments, a hole is provided on the conductive plate, and a nut is provided on one side of the hole. The end of the wire is passed through the hole and the nut, and a screw is used to pass through the hole from the opposite side of the nut and tightened with the nut, so that the wire is fixed to the conductive plate through the screw and the nut. In this way, the connection between the wire and the conductive plate is made stronger, and poor contact between the wire and the conductive plate is avoided. In addition, during each grounding operation, there is no need to move the wire or repeatedly disconnect and connect the wire, which avoids additional loss of the wire due to repeated disconnection and connection, and solves the problem of poor contact due to loss of the wire. In addition, since the wire and the conductive plate are fixedly connected, the operator does not need to manually connect the wire during the grounding operation, so there will be no problem of missed connection due to negligence, thereby improving the convenience and reliability of the grounding process.

[0058] In some embodiments, the conductive plate connects at least two sides of the support rod. Figure 2 The conductive plate 201 is fixedly connected to the top surface 2021 and right side surface 2022 of the support rod 202. This makes the connection between the conductive plate and the support rod more stable, preventing the conductive plate from separating from the support rod when subjected to external forces, thereby improving the convenience and reliability of the grounding process. Furthermore, because the conductive plate and the support rod are fixed in advance, the fixed connection operation is not required each time the grounding process is performed, thereby improving the efficiency of the grounding process.

[0059] In some embodiments, the insulating support structure further includes a support plate, and the at least two support rods include a fifth support rod and a sixth support rod; the fifth support rod and the sixth support rod are disposed opposite and spaced apart from each other, and are respectively fixedly connected to the support plate; and the fifth support rod and the sixth support rod enclose a hollow region. In this manner, even with only two support rods and the support plate, an insulating support structure can still be constructed, saving the cost of a grounding connection device.

[0060] For example, see Figure 3 , Figure 3 It is a structural schematic diagram of the insulating support structure provided in an embodiment of the present application, including a support rod 301, a support rod 302 and a support plate 303. The support rod 301 and the support rod 302 are two rectangular structures, and the support rod 301, the support rod 302 and the support plate 303 enclose a rectangular hollow area 304.

[0061] In some embodiments, the fifth support rod and the sixth support rod are arranged in parallel.

[0062] In some embodiments, the support rod and the support plate can be connected by bundling with a wire harness, or can be fixed by gluing with an adhesive material, or the support rod or the support plate can be hot-melted to connect the two.

[0063] In some embodiments, the support plate includes a hole structure, and a wire harness made of insulating material is passed through the hole structure of the support plate and bundled with the fifth support rod and the sixth support rod, so that the fifth support rod and the sixth support rod are fixedly connected to the support plate respectively.

[0064] In some embodiments, the distance between the fifth support rod and the sixth support rod is less than the length of the conductive plate; the first end of the conductive plate is fixedly connected to the fifth support rod, and the second end of the conductive plate is fixedly connected to the sixth support rod.

[0065] In some embodiments, the at least two support rods include a first support rod, a second support rod, a third support rod, and a fourth support rod. Figure 4 , the first support rod 401 and the second support rod 402 are arranged opposite to each other and at intervals, the third support rod 403 and the fourth support rod 404 are arranged opposite to each other and at intervals, and the first support rod 401 and the second support rod 402 are located above the third support rod 403 and the fourth support rod 404. The third support rod 403 is fixedly connected to the first support rod 401 and the second support rod 402 near both ends, and the fourth support rod 404 is fixedly connected to the first support rod 401 and the second support rod 402 near both ends. Among them, the first support rod 401, the second support rod 402, the third support rod 403 and the fourth support rod 404 enclose a hollow area. In this way, the four support rods make the insulating support structure have a higher height, so that the conductive plate can be better suspended, and more space is reserved for the conductive plate to undergo flexible deformation.

[0066] In some embodiments, the first support rod and the second support rod are arranged in parallel, and the third support rod and the fourth support rod are arranged in parallel. Thus, the hollow area formed by the multiple support rods arranged in parallel is more regular, and the conductive plate covering the hollow area deforms more evenly when the energy acquisition box to be tested is placed. The energy acquisition box to be tested on the conductive plate is less likely to slide off, thereby improving the safety and reliability of grounding the energy acquisition box to be tested.

[0067] In some embodiments, a folded edge can be provided at the end of the conductive plate not connected to the support rod, so that the end of the conductive plate naturally forms a baffle. In this way, when the energy acquisition box to be tested is placed on the conductive plate, the folded edge can prevent the energy acquisition box from sliding off, thereby improving the contact stability between the conductive plate and the energy acquisition box to be tested.

[0068] In some embodiments, the support rods can be fixedly connected by a wire harness, glue, or nails. In this way, there is no need to repeatedly connect the support rods each time the grounding process is performed, thereby improving the convenience and reliability of the grounding process.

[0069] In some embodiments, the distance between the third support rod and the fourth support rod is smaller than the length of the conductive plate, the first end of the conductive plate is fixedly connected to the third support rod, and the second end of the conductive plate is fixedly connected to the fourth support rod.

[0070] In some embodiments, the conductive plate is a metal plate having a thickness less than a preset thickness, and the metal plate can be flexibly deformed under the gravity of the energy collection box to be measured. For example, the conductive plate is a thin copper sheet, a thin aluminum sheet, a thin silver sheet, or a thin nickel sheet. In the embodiment of the present application, the conductive plate is set to be a thin copper sheet as an example. Among them, the preset thickness can be set according to the material of the conductive plate. The preset thickness is usually between 0.2 millimeters (mm) and 1 mm. In the case where the density of the material is relatively high and deformation is not easy to occur, the preset thickness is relatively small (such as 0.3 mm). In the case where the density of the material is relatively low and deformation is easy to occur, the preset thickness is relatively large (such as 0.9 mm). In this way, when the energy collection box to be measured is placed on the conductive plate, the conductive plate will undergo flexible deformation, thereby increasing the contact area with the energy collection box to be measured, so that the energy collection box to be measured and the conductive plate are in better contact, and the contact stability is improved.

[0071] In this way, the operation of placing the energy acquisition box to be tested of the metal box body on the conductive plate in the embodiment of the present application is larger in scope and easier to detect than the operation of clamping the energy acquisition box by a wire clamp in the prior art, so the operator is not likely to miss this step. Moreover, compared with achieving contact by clamping with a wire clamp, the method of making the energy acquisition box to be tested contact with the conductive plate by the gravity of the energy acquisition box to be tested can not only increase the contact area, but also make the contact tighter and less likely to fall off. Therefore, the embodiment of the present application fundamentally improves the implementation method of the grounding process, abandons the use of a wire clamp, and thereby solves the problem of unstable clamping of the wire clamp and easy omission by the operator, thereby improving the convenience and reliability of the grounding process.

[0072] In some embodiments, the ground connection device further includes a first cooling device, which is disposed below the conductive plate and is used to cool the conductive plate.

[0073] In some embodiments, the first cooling device includes a cooling container and a coolant. The cooling container is arranged in the hollow area, and the cooling container contains the coolant. When the energy collection box to be measured is placed on the conductive plate, the conductive plate undergoes flexible deformation so as to approach the first cooling device, and the first cooling device dissipates heat from the conductive plate. Here, the cooling container can prevent liquid leakage, and there is an opening on the top for injecting or replacing the coolant. The cooling container can be made of plastic, glass, etc. The coolant is used to absorb and transfer the heat of the conductive plate. The coolant can be a water-based coolant, an ethylene glycol coolant, an oil-based coolant, etc.

[0074] In some embodiments, the first cooling device is a fan or blower. The first cooling device forces air to flow, thereby increasing air flow speed and improving heat dissipation efficiency.

[0075] In some embodiments, the ground connection device further includes a heat sink fixedly connected to both ends of the conductive plate for dissipating heat from the conductive plate. The heat sink may be a heat sink. Installing the heat sink at both ends of the conductive plate increases the heat dissipation area, thereby improving heat dissipation efficiency. The heat sink may be made of a material with good thermal conductivity, such as aluminum or copper.

[0076] In this way, by cooling and dissipating the heat of the conductive plate, it is possible to prevent the conductive plate from being severely deformed in the event of overheating, or heat accumulation from causing charge disorder, which in turn causes the device to malfunction or affects the accuracy of the test.

[0077] In this way, the grounding connection device provided in the embodiment of the present application breaks the conventional thinking. Instead of modifying the wire clamp on the basis of the existing grounding connection device, it directly and fundamentally improves the structure of the grounding connection device. The grounding connection device provided in the embodiment of the present application does not need to be connected to the wire through the wire clamp, so there will be no problem of poor contact caused by the wire clamp or the wire. The various parts of the grounding connection device provided in the embodiment of the present application are fixedly connected and only need to be connected once during production. The connection between the various parts is firm and not easy to fall off. There is no need to repeat the connection each time the grounding operation is performed, so the problem of poor contact between the various parts caused by negligence can be avoided. In addition, the grounding connection device provided in the embodiment of the present application is made of common materials, has low material cost, is easy to manufacture, and is easy to mass produce. When grounding the energy box to be tested, the operator only needs to place the energy box to be tested on the conductive plate, which is easy to operate, avoids the phenomenon of ungrounded due to poor contact, and avoids the problem of the operator forgetting to clamp the wire clamp, thereby improving the convenience and reliability of grounding the energy box to be tested.

[0078] Below, the exemplary application and implementation of the energy box testing system provided in the embodiments of the present application will be described.

[0079] In some embodiments, the energy box testing system includes: an energy box to be tested, a grounding connection device, and a grounding lead; the body of the energy box to be tested is made of metal; the energy box to be tested is placed on a conductive plate of the grounding connection device, the body of the energy box to be tested contacts the conductive plate, and the conductive plate flexibly deforms under the gravity of the energy box to be tested; and the wire is connected to the grounding lead. In this way, no matter what shape the body of the energy box to be tested is, when the energy box to be tested is placed on the conductive plate of the grounding connection device, the conductive plate will flexibly deform due to the gravity of the energy box to be tested, and can form line contact and surface contact with the energy box to be tested, thereby increasing the contact area, avoiding the phenomenon of ungrounded due to poor contact, and improving the convenience and reliability of grounding the energy box to be tested.

[0080] See also Figure 6 , Figure 6 This is a schematic diagram of the structure of the energy collection box testing system provided in an embodiment of the present application. The energy collection box 604 is placed on the conductive plate 603 of the ground connection device. The box body of the energy collection box 604 contacts the conductive plate 603, which flexibly deforms, and the wire 601 is connected to the ground lead 602.

[0081] In some embodiments, the energy harvesting box includes multiple components and a box body that accommodates these components. Figure 7 The energy harvesting box includes a box body 701, which contains a transformer 702, an inductor 703, and a low-voltage capacitor 704. Transformer 702 is used to reduce high voltage to a suitable voltage to meet the voltage requirements of the circuits or devices within the energy harvesting box; inductor 703 is used to suppress high-frequency noise and transient interference in the current, making the output energy more stable; and low-voltage capacitor 704 is used to store electrical energy. When the energy harvesting box is harvesting energy, the capacitor can temporarily store some energy and release it when needed, which can smooth the output and reduce voltage instability caused by fluctuations during the energy harvesting process.

[0082] In some embodiments, the energy box testing system further includes an insulating operating table, which is used to place a grounding connection device. The insulating operating table is provided with a hole structure, and the grounding lead is movably inserted into the hole structure.

[0083] In some embodiments, the insulating operating table is an insulating base provided with a plurality of hole structures. Figure 5 The insulating base 501 includes multiple rectangular hole structures 502. This allows the grounding connection device to be placed on the insulating base, and the grounding connection device's wires can be passed through the hole structures to connect to the ground lead, saving wire length and making the grounding connection device look neater. The hole structures also allow heat dissipation during grounding of the energy box to be tested, preventing temperature from affecting test results.

[0084] In some embodiments, the insulating support structure is fixedly connected to the insulating base, wherein the first support rod and the second support rod are respectively fixedly connected to the insulating base. The support rods and the insulating base can be fixedly connected using a wire harness, glue, or nails. Alternatively, a wire harness made of insulating material is passed through a hole structure in the insulating base and bundled to the first and second support rods, thereby fixing the first and second support rods to the insulating base. In this way, using the hole structure of the insulating base to fix the first and second support rods is not only convenient and fast, but also improves the stability of the connection.

[0085] In some embodiments, the insulating operating table is provided with a receiving cavity, and the grounding connection device is embedded in the receiving cavity; the receiving cavity is provided with an opening structure on the top surface of the operating table, and the opening structure and the conductive plate are located in the same plane; the hole structure is provided on the bottom wall of the receiving cavity. For example, a receiving groove is provided in the middle position of the insulating operating table, the size of the receiving groove matches the size of the grounding connection device, the grounding connection device is embedded in the receiving groove, and the conductive plate of the grounding connection device is flush with the upper surface of the operating table. In this way, if there are multiple energy collection boxes to be tested that need to be tested, or the energy collection box to be tested is large in size and weight and it is inconvenient to place it directly on the conductive plate, the energy collection box to be tested can be placed on the operating table in advance. When performing the grounding process, it is only necessary to push the energy collection box to be tested directly to the opening structure to place the energy collection box to be tested on the conductive plate. When the test is completed, it is also only necessary to push the energy collection box to be tested away. In this way, the operating steps of the grounding process are further simplified, and the convenience and efficiency of the grounding process are improved.

[0086] In some embodiments, the energy harvesting box testing system further includes a second cooling device for cooling the energy harvesting box under test and the grounding connection device. The second cooling device can be mounted on the surface of an insulating workbench or within a receiving cavity of the workbench. The second cooling device is a fan or blower that forces air to flow, increasing the air flow rate and thereby dissipating heat from the energy harvesting box under test and the grounding connection device as a whole, further improving heat dissipation efficiency.

[0087] The energy box test system provided in the embodiment of the present application does not modify the wire clamp, but abandons the use of the wire clamp and adopts the above-mentioned grounding connection device to realize a new grounding processing method. Among them, the energy box test system includes the energy box to be tested, the above-mentioned grounding connection device and the grounding lead. The box body of the energy box to be tested is made of metal. The energy box to be tested is placed on the conductive plate of the grounding connection device. The box body of the energy box to be tested is in contact with the conductive plate. The conductive plate is flexibly deformed under the gravity of the energy box to be tested, and the wire is connected to the grounding lead. Different from the related art that uses a wire clamp to connect the energy box to the grounding pin for grounding processing, the energy box test system provided in the embodiment of the present application only needs to place the energy box to be tested on the grounding connection device. Since there is no need to clamp the wire clamp, there will be no problem of unstable clamping of the wire clamp. During the entire grounding process, the wire will not be moved or repeatedly disconnected and connected, so even if it is used multiple times, it will not cause additional loss to the wire, thereby avoiding the problem of poor contact of the wire.

[0088] In summary, the grounding connection device provided in the embodiment of the present application includes: an insulating support structure, a conductive plate and a wire. The connection between the various parts is stable and not easy to separate. The production cost is low, the difficulty is small, and it is easy to mass produce. When the energy box to be tested is grounded, the operator only needs to place the energy box to be tested on the conductive plate. The operation is convenient, and the phenomenon of ungrounded caused by poor contact is avoided, and the problem of the operator forgetting to clamp the wire clamp is also avoided. The embodiment of the present application solves multiple problems such as unstable clamping of the wire clamp, poor conductive contact, and negligence of the operator to forget to clamp, breaking the barriers of conventional thinking, abandoning the idea of ​​using a wire clamp to connect the energy box to the grounding pin in the prior art, and fundamentally transforming the implementation method of the grounding process, thereby improving the convenience and reliability of the grounding process of the energy box to be tested.

[0089] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent replacements, and improvements made within the spirit and scope of the present application are included in the scope of protection of the present application.
