[0001] The utility model relates to the technical field of current sensors, in particular to a current sensor which is easy to install and fix. Background Art

[0002] A current sensor is a detection device that can sense the information of the measured current and convert the sensed information into an electrical signal or other required form of information output that meets certain standards according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control.

[0003] During installation, current sensors in the prior art are typically fixed with screws through reserved holes. To prevent the current sensors from loosening, multiple sets of screws are required to secure the current sensors, which increases installation time and reduces efficiency. Furthermore, the current sensors require calibration and replacement after extended use. Repeated disassembly and assembly can easily damage the PCB, shortening their service life. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a current sensor that is easy to install and fix.

[0005] The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions: a current sensor that is easy to install and fix, including a current sensor body, a mounting plate is provided at the bottom of the current sensor body, a plug-in slot is provided on the upper surface of the mounting plate, a mounting slot is provided on the inner wall of the plug-in slot, a movable slot connected to the mounting slot is provided on the upper surface of the mounting plate, a plug-in block that is plugged into and matched with the plug-in slot is fixed to the bottom of the current sensor body, a fixing slot that is plugged into and matched with the mounting slot is provided on the side wall of the plug-in block, a fixing component for fixing the plug-in block is installed on the mounting plate, and the fixing component includes a fixing block that is slidably connected to the inner wall of the mounting slot and plug-fitted with the fixing slot, and a movable rod that is fixed to the upper surface of the fixed block and slidably connected to the inner wall of the movable slot.

[0006] By adopting the above technical solution, when the current sensor body needs to be installed, the plug-in block is aligned with the plug-in slot and inserted so that the plug-in block is plugged into the plug-in slot, and then the fixed block is moved to a state of plugging into the fixed slot by moving the rod, thereby fixing the current sensor on the mounting plate, eliminating the tedious operation of fixing with multiple sets of screws, and facilitating the installation and disassembly of the current sensor.

[0007] Furthermore, the fixing assembly also includes a clamping spring arranged in the installation groove, one end of the clamping spring is fixed to the inner wall of the installation groove, and the other end of the clamping spring is fixed to the side wall of the fixing block.

[0008] By adopting the above technical solution, the fixing block remains plugged into the fixing slot under the elastic force of the pressing spring, which reduces the probability of the fixing block detaching from the fixing slot and enhances the stability of the fixing assembly.

[0009] Furthermore, the upper surface of the fixing block is provided with a paving portion that cooperates with the bottom of the plug-in block.

[0010] By adopting the above technical solution, when the plug-in block is inserted into the plug-in slot, the fixed block is squeezed into the installation slot through the yielding portion. After the plug-in block is plugged into the plug-in slot, the fixed slot is aligned with the installation slot. At this time, the fixed block automatically enters the fixed slot and plugs in under the elastic force of the tightening spring, eliminating the tedious operation of the staff to pull the fixed block by moving the rod, and facilitating the rapid fixation of the current sensor body.

[0011] Furthermore, a first magnetic block is embedded in the inner wall of the movable groove, and a second magnetic block that is magnetically attracted to the first magnetic block is embedded in the side wall of the movable rod.

[0012] By adopting the above technical solution, when disassembling the current sensor body, the staff pulls the movable rod to the side of the movable slot away from the plug-in block, and makes the first magnetic block and the second magnetic block magnetically attracted to each other, and adsorbs and fixes the movable rod on the inner wall of the movable slot, so that the fixed block remains in the installation slot, eliminating the tedious operation of the staff pulling the movable rod with one hand and disassembling the current sensor with the other hand, and facilitating the rapid disassembly of the current sensor body.

[0013] Furthermore, a shielding plate is fixedly sleeved on the movable rod, and the orthographic projection area of the shielding plate is larger than the slot area of the movable slot.

[0014] By adopting the above technical solution, the shielding plate shields the opening of the movable slot, thereby reducing the probability of external dust and debris entering the installation slot through the movable slot.

[0015] Furthermore, a chamfer is provided at the intersection between the inner wall of the plug slot and the upper surface of the mounting plate.

[0016] By adopting the above technical solution and setting the chamfer, the difficulty of aligning the plug-in block with the plug-in slot is reduced, making it easier to align and insert the plug-in block with the plug-in slot.

[0017] Furthermore, a rubber pad is fixed to the bottom wall of the plug-in slot.

[0018] By adopting the above technical solution, the rubber pad is made of rubber material, which is elastic. The plug-in block cooperates with the plug-in slot and presses against the rubber pad, reducing the wear between the bottom of the plug-in block and the bottom wall of the plug-in slot.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. In this application, when the current sensor body needs to be installed, the plug-in block is aligned with the plug-in slot and inserted so that the plug-in block and the plug-in slot are plugged in and matched. Then, the fixed block is moved by the moving rod to a state of plugging and matching with the fixed slot, thereby fixing the current sensor on the mounting plate, eliminating the tedious operation of fixing with multiple sets of screws, and facilitating the installation and removal of the current sensor.

[0021] 2. In this application, the fixing block is kept plugged into the fixing slot under the elastic force of the pressing spring, which reduces the probability of the fixing block being detached from the fixing slot and enhances the stability of the fixing assembly;

[0022] 3. In the present application, when the plug-in block is inserted into the plug-in slot, the fixed block is squeezed into the installation slot by the yielding portion. After the plug-in block is plugged into the plug-in slot, the fixed slot is aligned with the installation slot. At this time, the fixed block automatically enters the fixed slot and plugs in under the elastic force of the tightening spring, eliminating the tedious operation of the staff to pull the fixed block by moving the rod, and facilitating the rapid fixation of the current sensor body.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] like Figure 1-3 As shown, an embodiment of the present application discloses a current sensor that is easy to install and fix, including a current sensor body 1, a mounting plate 2, a plug-in block 3 and a fixing component 4.

[0029] The current sensor body 1 is a commonly used current sensor body 1 in the prior art and is suitable for use in this embodiment. The mounting plate 2 is a rectangular plate-like structure, located at the bottom of the current sensor body 1. A plug-in slot 21 is defined on its top surface, and a mounting slot 22 is defined within the inner wall of the plug-in slot 21. A movable slot 23 is defined on its top surface, communicating with the mounting slot 22. The plug-in block 3 is a rectangular parallelepiped structure, fixed to the bottom of the current sensor body 1. The plug-in block 3 engages with the plug-in slot 21, and a fixed slot 31 is defined on its side wall, which mates with the mounting slot 22.

[0030] The fixing assembly 4 is mounted on the mounting plate 2 and is used to secure the plug-in block 3. The fixing assembly 4 includes a fixing block 41, a movable rod 42, and a retaining spring 43. The fixing block 41 is a rectangular parallelepiped structure that is slidably connected to the inner wall of the mounting slot 22 and plugs into the fixing slot 31. The movable rod 42 is a vertically mounted rectangular rod-shaped structure that is fixed to the upper surface of the fixing block 41 and slidably connected to the inner wall of the movable slot 23. The retaining spring 43 is disposed within the mounting slot 22. One end of the retaining spring 43 is secured to the inner wall of the mounting slot 22, and the other end is secured to the side wall of the fixing block 41.

[0031] When the current sensor body 1 needs to be installed, the plug-in block 3 is aligned with the plug-in slot 21 and inserted so that the plug-in block 3 is plugged into the plug-in slot 21, and then the fixing block 41 is moved to a state of plugging into the fixing slot 31 by the moving rod 42, thereby fixing the current sensor on the mounting plate 2, eliminating the tedious operation of fixing with multiple sets of screws, and facilitating the installation and disassembly of the current sensor. The fixing block 41 remains plugged into the fixing slot 31 under the elastic force of the pressing spring 43, reducing the probability of the fixing block 41 detaching from the fixing slot 31 and enhancing the stability of the fixing component 4.

[0032] In order to facilitate the rapid fixation of the current sensor body 1, a relief portion 411 is provided on the upper surface of the fixing block 41 for cooperating with the bottom of the plug-in block 3. When the plug-in block 3 is inserted into the plug-in slot 21, the relief portion 411 squeezes the fixing block 41 into the installation slot 22. After the plug-in block 3 is plugged into the plug-in slot 21, the fixing slot 31 is aligned with the installation slot 22. At this time, the fixing block 41 automatically enters the fixing slot 31 and is plugged in under the elastic force of the tightening spring 43, eliminating the tedious operation of the staff to pull the fixing block 41 by moving the rod 42, thereby facilitating the rapid fixation of the current sensor body 1.

[0033] In order to facilitate the rapid disassembly of the current sensor body 1, a first magnetic block 5 is embedded in the inner wall of the movable groove 23, and a second magnetic block 6 that is magnetically attracted to the first magnetic block 5 is embedded in the side wall of the movable rod 42. When disassembling the current sensor body 1, the staff pulls the movable rod 42 to the side of the movable groove 23 away from the plug-in block 3, and makes the first magnetic block 5 and the second magnetic block 6 magnetically attracted, and adsorbs and fixes the movable rod 42 on the inner wall of the movable groove 23, so that the fixed block 41 remains in the installation groove 22, eliminating the tedious operation of the staff pulling the movable rod 42 with one hand and disassembling the current sensor with the other hand, thereby facilitating the rapid disassembly of the current sensor body 1.

[0034] In order to reduce the probability of external dust and debris entering the installation groove 22 through the movable groove 23, a baffle plate 7 is fixedly provided on the movable rod 42. The positive projection area of the baffle plate 7 is larger than the slot area of the movable groove 23. The baffle plate 7 blocks the slot of the movable groove 23, thereby reducing the probability of external dust and debris entering the installation groove 22 through the movable groove 23.

[0035] In order to facilitate the alignment and insertion of the plug-in block 3 with the plug-in slot 21, a chamfer 24 is provided at the intersection between the inner wall of the plug-in slot 21 and the upper surface of the mounting plate 2. The setting of the chamfer 24 reduces the difficulty of aligning the plug-in block 3 with the plug-in slot 21, thereby facilitating the alignment and insertion of the plug-in block 3 with the plug-in slot 21.

[0036] In order to reduce the wear between the bottom of the plug-in block 3 and the inner bottom wall of the plug-in slot 21, a rubber pad 8 is fixed to the inner bottom wall of the plug-in slot 21. The rubber pad 8 is made of rubber material, which is elastic. The plug-in block 3 cooperates with the plug-in slot 21 and presses against the rubber pad 8, thereby reducing the wear between the bottom of the plug-in block 3 and the inner bottom wall of the plug-in slot 21.

[0037] The use principle of a current sensor that is easy to install and fix in this embodiment is as follows: when the current sensor body 1 needs to be installed, the plug-in block 3 is aligned with the plug-in slot 21 and inserted so that the plug-in block 3 is plugged into the plug-in slot 21, and then the fixing block 41 is moved to a state of plugging and matching with the fixing slot 31 by the moving rod 42, thereby fixing the current sensor on the mounting plate 2, eliminating the tedious operation of fixing with multiple sets of screws, and facilitating the installation and disassembly of the current sensor. The fixing block 41 maintains the plug-in state with the fixing slot 31 under the elastic force of the pressing spring 43, reducing the probability of the fixing block 41 detaching from the fixing slot 31 and enhancing the stability of the fixing component 4.
