[0042] As can be seen from the above, the testing device for detecting current provided by this utility model embodiment includes: a display mounted sequentially on the upper liner of the cabinet along a first direction and a main control module mounted on the middle liner of the cabinet; the main control module includes a main control module housing structure, a first FPGA board, three first Hall sensors, and a first outgoing connector; the first FPGA board is mounted in a relatively closed first cavity enclosed by the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure along a second direction, through which the first outgoing connector passes; the first FPGA board extends along the second direction, one end of the first FPGA board along the second direction is electrically connected to one end of the first outgoing connector located in the first cavity, the other end of the first outgoing connector located outside the first cavity is electrically connected to the display, and the other end of the first FPGA board along the second direction is electrically connected to the three Hall sensors respectively, the three Hall sensors are mounted on the other side surface of the main control module housing structure along the second direction, and the three first Hall sensors are located outside the first cavity, and all three first Hall sensors are electrically connected to a first current-to-be-detected device inside the cabinet; wherein, the first direction and the second direction are perpendicular to each other.

The first FPGA board transmits the first current signal to the display through the first outgoing connector, thereby realizing the current detection of the first current-detecting device.

[0043] The innovative aspects of this utility model embodiment include:
[0044] 1. The current signal of the first current device to be tested in the cabinet is collected by three first Hall sensors and transmitted to the first FPGA board. The first FPGA board transmits the first current signal to the display through the first outgoing connector, thereby realizing the current detection of the first current device to be tested. The present invention only includes components related to current detection, so that the test device for detecting current provided by the present invention is small in size and can be installed in the dispersed limited space in the cabinet, so as to realize the function of current detection of devices inside large integrated cabinets.
[0045] 2. Since the testing device for detecting current provided in this embodiment of the utility model is small in size, it can be installed in the dispersed limited space inside the cabinet. Therefore, it also provides a solution for the temporary functional requirements added to the cabinet later.
[0046] 3. The testing device for detecting current provided in this embodiment of the utility model has a simple structure, is easy to assemble and operate, and has low processing cost.
[0047] 4. By setting a first screw mounting hole at the other end of the main housing of the main control module along the first direction, screw installation with the middle liner plate can be achieved, which is convenient for cabinets with high integration.
[0048] 5. Electrical connection between the first FPGA board and the relay board is achieved by connecting the first connector socket to the first connector plug. Electrical connection between the relay and the three first external connectors is achieved by connecting the three second connector sockets to the corresponding first external connector plugs, allowing the relay board to output signals from the first FPGA board through the three first external connectors. Electrical connection between the first FPGA board and the vertical PCB board is achieved by connecting the two third connector sockets to the corresponding two second connector plugs. Electrical connection between the vertical PCB board and the two second external connectors is achieved by connecting the two fourth connector sockets to the corresponding two second external connector plugs, allowing the vertical PCB board to output signals from the first FPGA board through the two second external connectors.
[0049] 6. Since the relay board, the first FPGA board, and the first power board are arranged in layers, the volume occupied by the three boards is greatly reduced, which further reduces the volume of the main control module. This allows the main control module to be installed in the limited space of the cabinet, enabling it to perform current detection on the devices inside the large integrated cabinet.
[0050] 7. By connecting the third pair of connector plugs to the socket of the first outgoing connector located in the first cavity, the electrical connection between the first FPGA board and the first outgoing connector is realized, so that the first FPGA board can send current signals to the display for display through the first outgoing connector.
[0051] 8. By setting a first groove on the inner wall near the first power board and installing a first thermally conductive silicone pad in the first groove, with the first thermally conductive silicone pad in contact with the first power board, the first power board is cooled down to prevent overheating and failure.
[0052] 9. The second current signal of the second current device to be detected in the cabinet is collected by three second Hall sensors and transmitted to the second FPGA board through the third outgoing connector. The second FPGA board transmits the second current signal to the first FPGA board through the second outgoing connector and the fourth outgoing connector in sequence. The first FPGA board transmits the second current signal to the display through the first outgoing connector for display, thereby realizing the current detection of the second current device to be detected. The remote module only contains the second FPGA board, which makes the remote module small in size and can be installed in the dispersed limited space in the cabinet to realize the function of current detection of devices inside large integrated cabinets.
[0053] 10. By connecting the remote module to the main control module, and the main control module to the display, the second current signal detected by the remote module can also be transmitted to the display for display via the main control module, eliminating the need to add a new display, reducing the number of displays and lowering costs.
[0054] 11. By setting a second screw mounting hole at the other end of the main housing of the remote module along the first direction, screw installation with the lower liner is achieved, which is convenient for cabinets with high integration.
[0055] 12. The electrical connection between the second power board and the second FPGA board is achieved by connecting the fifth pair of connector sockets and the fourth pair of connector plugs, so that the second power board supplies power to the second FPGA board.
[0056] 13. By setting a second groove on the inner wall near the second power board and installing a second thermally conductive silicone pad in the second groove, with the second thermally conductive silicone pad in contact with the second power board, the second power board is cooled down to prevent overheating and failure.

[0071] This utility model discloses a testing device for detecting current, which can realize the function of current detection of devices inside large integrated cabinets. The following is a detailed description of this utility model embodiment.
[0072] Figure 1 This is a schematic diagram of a testing device for detecting current provided in an embodiment of the present invention. Figure 2 This is a front view of the main control module provided in an embodiment of the present utility model. Figure 3 A side view of the main control module provided in an embodiment of this utility model. Figure 4 This is a top view of the main control module provided in an embodiment of the present utility model.
[0073] See Figures 1-4 The current detection device provided in this embodiment includes a display 1 and a main control module 2, which are sequentially mounted on the upper liner 20 of the cabinet along a first direction. The mounting method can be screw mounting. The display 1 can be an LCD display, and its size can be selected according to actual usage requirements. Inside the cabinet, the upper liner 20, the middle liner 30, and the lower liner 30 are sequentially arranged along the first direction, with the lower liner 30 close to the ground.
[0074] The main control module 2 includes a main control module housing structure, a first FPGA (Field Programmable Gate Array) board 21, three first Hall sensors 22, and a first outgoing connector 23. For example, the first FPGA board 21 is a PCB (Printed Circuit Board).
[0075] The first FPGA board 21 is installed in a relatively closed first cavity enclosed by the main control module housing structure. The main control module housing structure has a first outgoing connector mounting hole on one side surface along the second direction. The first outgoing connector 23 passes through the first outgoing connector mounting hole. In this embodiment of the utility model, the first cavity is relatively closed, that is, the housing structure is not completely closed.
[0076] The first FPGA board 21 extends along the second direction. One end of the first FPGA board 21 along the second direction is electrically connected to one end of the first outgoing connector 23 located inside the first cavity. The other end of the first outgoing connector 23 located outside the first cavity is electrically connected to the display 1. The other end of the first FPGA board 21 along the second direction is electrically connected to three Hall sensors 22. The three Hall sensors 22 are installed on the other side surface of the main control module housing structure along the second direction, and the three Hall sensors 22 are located outside the first cavity. All three Hall sensors 22 are electrically connected to the first current-to-be-detected device inside the cabinet.
[0077] The first direction and the second direction are perpendicular to each other.
[0078] In this application, the first direction is perpendicular to the ground, and the third direction is the length direction of each of the rack's panels, and the first, second, and third directions are mutually perpendicular. However, it should be noted that "perpendicular" in this application is not absolutely perpendicular, but can be 90°±10°. Similarly, "parallel" in this application is not absolutely parallel, but can be 180°±10°.
[0079] The working principle of the testing device for detecting current provided in this embodiment of the utility model is as follows:
[0080] Three first Hall sensors 22 collect the first current signal of the first current device to be tested in the cabinet and transmit it to the first FPGA board 21. The first FPGA board 21 transmits the first current signal to the display 1 through the first outgoing connector 23 for display, thereby realizing the current detection of the first current device to be tested.
[0081] In summary, the testing device for detecting current provided in this embodiment of the present invention includes: a display 1 and a main control module 2 installed sequentially on the upper liner 20 of the cabinet along a first direction; the main control module 2 includes a main control module housing structure, a first FPGA board 21, three first Hall sensors 22, and a first outgoing connector 23; the first FPGA board 21 is installed in a relatively closed first cavity enclosed by the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure along a second direction, and the first outgoing connector 23 passes through the first outgoing connector mounting hole ... a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing structure, and a first outgoing connector mounting hole is provided on one side surface of the main control module housing Board A 21 extends along the second direction. One end of the first FPGA board 21 along the second direction is electrically connected to one end of the first outgoing connector 23 located inside the first cavity. The other end of the first outgoing connector 23 located outside the first cavity is electrically connected to the display 1. The other end of the first FPGA board 21 along the second direction is electrically connected to three Hall sensors 22. The three Hall sensors 22 are installed on the other side surface of the main control module housing structure along the second direction, and the three Hall sensors 22 are located outside the first cavity. All three Hall sensors 22 are electrically connected to the first current-to-be-detected device inside the cabinet. The first direction and the second direction are perpendicular to each other. Therefore, the current signal of the first current device to be tested in the cabinet is collected by three first Hall sensors 22 and transmitted to the first FPGA board 21. The first FPGA board 21 transmits the first current signal to the display 1 through the first outgoing connector 23 for display, thereby realizing the current detection of the first current device to be tested. The present invention only includes components related to current detection, so that the test device for detecting current provided by the present invention is small in size and can be installed in the dispersed limited space in the cabinet to realize the function of current detection of devices inside large integrated cabinets.
[0082] Furthermore, since the testing device for detecting current provided in this embodiment of the utility model is small in size, it can be installed in the dispersed limited space inside the cabinet, thus providing a solution for the temporary functional requirements added to the cabinet later.
[0083] Meanwhile, the testing device for detecting current provided in this embodiment of the utility model has a simple structure, is easy to assemble and operate, and has low processing cost.
[0084] See also Figures 2-4 The main control module housing structure includes a main control module housing 24, a main control module front baffle 25, a main control module top cover 26, and a main control module side baffle 27. The main control module housing 24 is provided with multiple wire mounting holes; for example, the size of the wire mounting holes is 10.5mm × 25mm. The main control module housing 24 has dimensions of 150mm × 100mm × 60mm and a thickness of 2mm.
[0085] The main control module housing 24 is a housing structure with an opening at one end along a first direction, an opening and a mounting platform 28 at one end along a second direction (the mounting platform 28 extending along the first direction), and an opening at one end along a third direction. In other words, the main control module housing 24 is a housing structure without seals at three ends. An opening at one end is considered a full opening, while an opening at one end is considered a partial opening. The end along the second direction has both an opening and a mounting platform 28, meaning that the opening at the end along the second direction is not fully open.
[0086] See also Figures 2-4 The main control module top cover 26 is installed at the opening end of the main control module main housing 24 along the first direction. The main control module front baffle 25 is installed at the opening end of the main control module main housing 24 along the second direction, and the main control module front baffle 25 is close to the main control module top cover 26. The main control module side baffle 27 is installed at the opening end of the main control module main housing 24 along the third direction. The installation method can be screw installation. Since the main control module front baffle 25 is installed at the opening end of the main control module main housing 24 along the second direction, and the main control module front baffle 25 is close to the main control module top cover 26, it indicates that the opening end of the main control module main housing 24 along the second direction is close to the main control module top cover 26.
[0087] The main control module housing 24, the main control module front baffle 25, the main control module top cover 26, and the main control module side baffle 27 are assembled to form the first cavity.
[0088] The other end of the main control module housing 24 along the first direction is mounted on the intermediate liner plate 30. The main control module housing 24 along the first direction can be mounted on the intermediate liner plate by providing four first screw mounting holes at the other end of the main control module housing 24 along the first direction, and mounting it on the intermediate liner plate 30 by four screws. For example, the size of the first screw mounting holes can be M5.
[0089] Therefore, by setting four first screw mounting holes at the other end of the main control module housing 24 along the first direction, screw installation with the middle liner plate 30 can be achieved, which is convenient for cabinets with high integration.
[0090] The main control module housing 24 has a first outgoing connector mounting hole on the side surface without an opening along the second direction. Three Hall sensors 22 are mounted on the outer surface of the mounting platform 28, which can be installed with screws, meaning the three Hall sensors 22 are located outside the first cavity. The first, second, and third directions are mutually perpendicular.
[0091] Figure 5 A partial cross-sectional view of the main control module provided in this embodiment of the present invention, see below. Figures 2-5 The main control module 2 also includes a relay board, a first power supply board 291, a vertical circuit board (PCB), three first external connectors 3, and two second external connectors 4. The first power supply board 291 is used to supply power to the main control module 2.
[0092] The first cavity contains three layers of boards arranged in sequence: a relay board, a first FPGA board 21, and a first power supply board 291, as well as a vertical PCB board on the side. For example, the relay board and the first power supply board 291 are PCB boards.
[0093] Specifically, the relay board, the first FPGA board 21, and the first power board 291 are sequentially disposed in the first cavity along the first direction, and the first power board 291 is mounted on the mounting table 28 on one side surface along the first direction. The mounting method can be screw mounting.
[0094] The first FPGA board 21 is mounted on one side of the first power board 291 along the first direction, and the relay board is mounted on one side of the first FPGA board 21 along the first direction, and the relay board is mounted on the other side of the first FPGA board 21 along the first direction. The mounting method can be copper stud mounting; for example, four copper studs are used to mount each pair of boards. Since the relay board, the first FPGA board 21, and the first power board 291 all have a certain number of electronic components, there are gaps between the three boards.
[0095] The first FPGA board 21 has a first mating connector socket on the other side of the first direction, and the relay board has a first mating connector plug on one side of the first direction that corresponds to the first mating connector socket. The first mating connector socket and the first mating connector plug are connected.
[0096] The relay has three second plug connector sockets 5 on the other side of the first direction, which correspond one-to-one with the three first external plug connectors. The main control module cover plate 26 has three first through holes on one side of the first direction, which correspond one-to-one with the three second plug connector sockets 5. Each second plug connector socket 5 passes through the corresponding first through hole and is plugged into the corresponding first external plug connector 3.
[0097] The first FPGA board 21 has two third-pair connector sockets at one end along the third direction. The upright PCB board extends along the first direction and is mounted on one side surface of the upright PCB board along the third direction to the main control module side baffle 27. The mounting method can be screw mounting. For example, the main control module side baffle 27 is provided with 4 PCB board mounting holes and is fixedly mounted to the upright PCB board by 4 screws. The size of the PCB board mounting holes can be 89.5mm × 51mm.
[0098] The PCB board has two second-pair connector plugs on the other side of the third direction, which correspond one-to-one with the two third-pair connector sockets. Each third-pair connector socket is plugged into the corresponding second-pair connector plug.
[0099] The PCB board has two fourth connector sockets 6 that correspond one-to-one with the two second external connectors 4 on one side surface along the third direction. The main control module side baffle 27 has two second through holes that correspond one-to-one with the two fourth connector sockets 6 on one side surface along the third direction. Each fourth connector socket 6 passes through the corresponding second through hole and is plugged into the corresponding second external connector 4.
[0100] Therefore, the electrical connection between the first FPGA board 21 and the relay board is achieved by connecting the first plug-in connector socket to the first plug-in connector plug. The electrical connection between the relay and the three first external plug-in connectors is achieved by connecting the three second plug-in connector sockets 5 to the plugs of the three corresponding first external plug-in connectors 3, so that the relay board can output the signal of the first FPGA board 21 to the outside through the three first external plug-in connectors 3. The electrical connection between the first FPGA board 21 and the vertical PCB board is achieved by connecting the two third plug-in connector sockets to the plugs of the two corresponding second plug-in connectors 3. The electrical connection between the vertical PCB board and the two second external plug-in connectors 4 is achieved by connecting the two fourth plug-in connector sockets 6 to the plugs of the two corresponding second external plug-in connectors 4, so that the vertical PCB board can output the signal of the first FPGA board 21 to the outside through the two second external plug-in connectors 4.
[0101] Furthermore, since the relay board, the first FPGA board 21, and the first power supply board 291 are arranged in layers, the volume occupied by the three boards is greatly reduced, further reducing the volume of the main control module 2. This allows the main control module 2 to be installed in a dispersed and limited space within the cabinet, enabling it to perform current detection on the devices inside a large integrated cabinet.
[0102] In one implementation, a third pair of connector plugs is provided at one end of the first FPGA board 21 along the second direction, and the third pair of connector plugs is inserted into the socket of the first outgoing connector 23 located in the first cavity.
[0103] Thus, by plugging the third pair of connectors into the socket of the first outgoing connector 23 located in the first cavity, the electrical connection between the first FPGA board 21 and the first outgoing connector 23 is realized, so that the first FPGA board 21 can send current signals to the display 1 for display through the first outgoing connector 23.
[0104] In one implementation, the main control module 2 also includes a first thermally conductive silicone pad.
[0105] The main control module housing 24 has a first groove on its inner wall near the first power board 291 along a first direction. A first thermally conductive silicone pad is installed in the first groove and abuts against the first power board 291. The installation method can be screw mounting. For example, the dimensions of the first groove are 48.2mm × 71.25mm × 0.7mm.
[0106] Therefore, by providing a first groove on the inner wall near the first power board 291 and installing a first thermally conductive silicone pad in the first groove, with the first thermally conductive silicone pad in contact with the first power board 291, the first power board 291 is cooled down, thus preventing the first power board 291 from overheating and malfunctioning.

[0108] See Figure 1 , Figures 6-9 The testing device for detecting current also includes:
[0109] The remote module 7 and three second Hall sensors are mounted on the lower liner 40 of the cabinet. The upper liner 20, middle liner 30 and lower liner 40 are arranged sequentially along the first direction. The three second Hall sensors are mounted on any one of the liners. The specific liner on which the sensors are mounted depends on the space available on that liner to accommodate all three sensors. The mounting method can be screw mounting.
[0110] The remote module 7 includes a remote module housing structure, a second FPGA board 71, a second outgoing connector 72, and a third outgoing connector 73. The second FPGA board 71 is installed in the second cavity enclosed by the remote module housing structure. The second FPGA board 71 extends along the second direction. The remote module housing structure has a second outgoing connector mounting hole on one side surface along the second direction and a third outgoing connector mounting hole on the other side surface along the second direction. The second outgoing connector 72 passes through the second outgoing connector mounting hole, and the third outgoing connector 73 passes through the third outgoing connector mounting hole.
[0111] The main control module 2 also includes a fourth outgoing connector 292, which passes through the first outgoing connector mounting hole. One end of the first FPGA board 21 along the second direction is electrically connected to the end of the fourth outgoing connector 292 located inside the first cavity. The end of the fourth outgoing connector 292 outside the first cavity is electrically connected to the end of the second outgoing connector 72 outside the second cavity. The end of the second outgoing connector 72 inside the second cavity is electrically connected to the end of the second FPGA board 71 along the second direction. The other end of the second FPGA board 71 along the second direction is electrically connected to the end of the third outgoing connector 73 inside the second cavity. The end of the third outgoing connector 73 outside the second cavity is electrically connected to three second Hall sensors. All three second Hall sensors are electrically connected to the second current-detecting device inside the cabinet.
[0112] The electrical connections between the first FPGA board 21 and the fourth outgoing connector 292, the second outgoing connector 72 and the second FPGA board 71, the second FPGA board 71 and the third outgoing connector 73, and the third outgoing connector 73 and the three second Hall sensors are all plug-and-socket connections. For details, please refer to the description of the plug-and-socket connections between the components in the main control module 2 above, which will not be repeated here.
[0113] The working principle of current detection via remote module 7 is as follows:
[0114] Three second Hall sensors collect the second current signal of the second current device to be detected in the cabinet and transmit it to the second FPGA board 71 through the third outgoing connector 73. The second FPGA board 71 transmits the second current signal to the first FPGA board 21 through the second outgoing connector 72 and the fourth outgoing connector 292 in sequence. The first FPGA board 21 transmits the second current signal to the display 1 through the first outgoing connector 23 for display, thereby realizing the current detection of the second current device to be detected.
[0115] Therefore, the second current signal of the second current device to be detected in the cabinet is collected by three second Hall sensors and transmitted to the second FPGA board 71 through the third outgoing connector 73. The second FPGA board 71 transmits the second current signal to the first FPGA board 21 through the second outgoing connector 72 and the fourth outgoing connector 292 in sequence. The first FPGA board 21 transmits the second current signal to the display 1 through the first outgoing connector 23 for display, thereby realizing the current detection of the second current device to be detected. The remote module 7 only contains the second FPGA board 71, which makes the remote module 7 small in size and can be installed in the dispersed limited space in the cabinet to realize the function of current detection of devices inside large integrated cabinets.
[0116] Furthermore, by connecting the remote module 7 to the main control module 2, and the main control module 2 to the display 1, the second current signal detected by the remote module 7 can also be transmitted to the display 1 for display via the main control module 2, eliminating the need to add a new display, thus reducing the number of displays and lowering costs.
[0117] See also Figures 6-9 The remote module 7 includes a remote module main housing 74, a remote module front baffle 75, and a remote module upper cover 76.
[0118] The remote module main housing 74 is a housing structure with an opening at one end along the first direction and an opening on one side surface along the second direction. Since the remote module main housing 74 has an opening on one side surface along the second direction instead of an opening at one end, the opening on one side surface along the second direction of the remote module main housing 74 is not a full opening.
[0119] The remote module top cover 76 is installed on the opening end of the remote module main housing 74 along the first direction, and the remote module front baffle 75 is installed on the opening end of the remote module main housing 74 along the second direction. The installation method can be screw installation.
[0120] The remote module main housing 74, the remote module front baffle 75, and the remote module upper cover 76 are assembled to form a second cavity.
[0121] The other end of the remote module main housing 74 along the first direction is mounted on the lower liner 40. The remote module main housing 74 is mounted on the lower liner 40 by providing four second screw mounting holes at the other end of the remote module main housing 74 along the first direction, and is mounted on the lower liner 40 by four screws. For example, the size of the second screw mounting holes can be M5.
[0122] Therefore, by setting four second screw mounting holes at the other end of the remote module main housing 74 along the first direction, screw installation with the lower liner 40 can be achieved, which is convenient for cabinets with high integration.
[0123] The remote module main housing 74 has a second outgoing connector mounting hole on one side surface with an opening along the second direction, and a third outgoing connector mounting hole on the other side surface of the remote module main housing 74 opposite to the remote module front baffle 75.
[0124] See also Figure 9 The remote module 7 also includes a second power board 77, which and the second FPGA board 71 are sequentially disposed in the second cavity along the second direction. The second power board 77 is used to supply power to the remote module 7.
[0125] The remote module main housing 74 has four mounting posts 741 on one side surface along the first direction. The second power board 77 is mounted on one side surface along the first direction of the second FPGA board 71, and the second FPGA board 71 is mounted on the four mounting posts 741 on one side surface along the first direction. The mounting method can be screw mounting. For example, the size of the screw used can be M2.
[0126] The second FPGA board 71 has a fifth pair of connector sockets on one side surface along the first direction, and the second power board 77 has a fourth pair of connector plugs on the other side surface along the first direction. The fifth pair of connector sockets and the fourth pair of connector plugs are connected.
[0127] Thus, by connecting the fifth pair of connector sockets to the fourth pair of connector plugs, an electrical connection is achieved between the second power board 77 and the second FPGA board 71, enabling the second power board 77 to supply power to the second FPGA board 71.
[0128] See also Figure 9 The remote module 7 also includes a second thermally conductive silicone pad 78.
[0129] The remote module main housing 74 has a second groove on its inner wall along the first direction near the second power board 77. A second thermally conductive silicone pad 78 is installed in the second groove and abuts against the second power board 77. The installation method can be screw mounting. For example, the dimensions of the first groove are 59mm × 59mm × 0.7mm.
[0130] Therefore, by providing a second groove on the inner wall near the second power board 77, and installing a second thermally conductive silicone pad 78 in the second groove, with the second thermally conductive silicone pad 78 in contact with the second power board 77, the second power board 77 is cooled down, thus preventing the second power board 77 from overheating and malfunctioning.
