Description

Technical Field

[0001] The utility model relates to the technical field of current sensors, in particular to a current sensor testing device. Background Art

[0002] A current sensor is a detection device that can sense the information of the measured current and transform the sensed information into an electrical signal or other required form of information output that meets certain standards according to certain rules, so as to meet the requirements of information transmission, processing, storage, display, recording and control. After the production of the current sensor is completed, it needs to be tested for current to determine whether it is qualified. The test of the current sensor generally needs to be carried out on a specific test tool. However, the existing current test tool can only test one product at a time during the test, and the sensor needs to be fixed to the copper busbar with screws. Each time the test product is changed, the wiring at both ends of the copper busbar needs to be removed and reconnected. The operation process is cumbersome, time-consuming, and the test efficiency is low.

[0003] A Chinese utility model patent, publication number CN219201894U, discloses a current sensor testing tool. The tool comprises at least a current sensor mounting base, a clamping device, a wiring copper block, and a copper busbar. The wiring copper block is detachably mounted at both ends of the current sensor mounting base. The clamping device is disposed at both ends of the current sensor mounting base and is capable of clamping the ends of the copper busbar against the wiring copper block. During testing, the copper busbar passes through the current sensor and is secured to the current sensor mounting base. The clamping device clamps the ends of the copper busbar against the wiring copper block. After the test is complete, the clamping device is opened to remove the copper busbar and current sensor. The tool can be easily removed by simply lifting and pressing the clamping device, making it easy to operate and capable of testing multiple current sensors at once.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned device drives the copper busbar to move up and down by manually moving the pressing rod. When the staff tests the current sensor, the staff needs to continuously lift the two pressing rods upward to make the copper busbar press against the current sensor fixing seat and remain stable. At this time, it is inconvenient for the staff to deal with emergencies. In actual use, it is easy for the staff to develop the habit of operating the two pressing rods with one hand, which poses certain safety hazards. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a current sensor testing device.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a current sensor testing device, comprising a base plate, a current sensor fixing base installed on the base plate, a wiring copper block arranged on the current sensor fixing base, and a copper busbar arranged on the wiring copper block, a plurality of mounting blocks are fixed on the upper surface of the base plate, a rotating groove is opened on the upper surface of the mounting block, a pressing rod is rotatably arranged in the rotating groove, a pressing head is fixed on the bottom surface of the pressing rod, a telescopic rod is connected to the bottom surface of the pressing rod, and a limiting component for limiting the telescopic rod is provided on the base plate.

[0007] By adopting the above technical solution, when a worker needs to test the current sensors, they only need to place multiple current sensors on the current sensor holder and pass the copper busbar through the multiple current sensors. Furthermore, the worker only needs to lift the pressing rod upward, which will move the pressing head downward and press against the copper busbar. The limit assembly is then activated, which will keep the pressing rod stable under the action of the limit assembly. The worker does not need to continuously apply upward force to the pressing rod, thus facilitating the worker's testing of the current sensors.

[0008] Furthermore, the telescopic rod includes a sliding rod rotatably arranged on the bottom surface of the pressing rod and a sleeve rod slidably connected to the sliding rod, and the bottom surface of the sleeve rod is fixed to the upper surface of the bottom plate.

[0009] Furthermore, a first limiting groove is provided on the side wall of the sliding rod, a second limiting groove is provided through the side wall of the sleeve rod, and the limiting assembly includes a limiting rod slidably arranged in the second limiting groove and a sliding block fixed to the end of the limiting rod.

[0010] By adopting the above technical solution, when the staff member lifts the pressing rod upward, the sliding rod moves upward under the action of the pressing rod, causing the first limiting groove to gradually approach and eventually align with the second limiting groove. The staff member then slides the sliding block, which connects the limiting rod with the first limiting groove under the action of the sliding block, thereby causing the limiting rod to limit the sliding rod, thereby keeping the pressing rod stable, without the staff member having to continuously apply upward force to the pressing rod.

[0011] Furthermore, a sliding groove is provided on the side wall of the limiting rod, a moving block is fixed on the inner wall of the second limiting groove, and the moving block is slidably connected to the sliding groove.

[0012] By adopting the above technical solution, the probability of the limiting rod and the second limiting groove being separated from each other is reduced, thereby improving the stability of the device and enhancing the user experience of the staff.

[0013] Furthermore, an annular block is rotatably provided on the side wall of the limiting rod, an annular threaded piece is connected to the annular block, and a threaded groove matching the annular threaded piece is provided on the side wall of the sleeve rod.

[0014] By adopting the above technical solution, when the staff slides the sliding block, the annular thread piece follows the limit rod and finally presses against the thread groove. At this time, the limit rod and the first limit groove are connected to each other. The staff only needs to rotate the annular thread piece to connect the annular thread piece and the thread groove to each other, so that the limit rod remains stable, thereby reducing the probability of the limit rod and the first limit groove being separated from each other at this time.

[0015] Furthermore, a connecting spring is fixed on the inner wall of the first limiting groove away from the second limiting groove, and a stabilizing rod is fixed to the other end of the connecting spring. The side wall of the stabilizing rod away from the connecting spring is flush with the side wall of the sliding rod.

[0016] By adopting the above technical solution, when the staff separates the annular thread sheet and the thread groove from each other, the limit rod is separated from the first limit groove under the action of the stabilizing rod and the connecting spring, thereby reducing the probability of the limit rod interfering with the movement of the sliding rod at this time, thereby improving the staff's user experience.

[0017] Furthermore, an iron rod is fixed to the bottom surface of the pressing rod, and a magnet block is fixed to the upper surface of the bottom plate.

[0018] By adopting the above technical solution, when the current sensor detection is completed, the staff needs to press the pressing rod downward. At this time, the iron rod and the magnet block are attracted to each other, thereby keeping the pressing rod stable. The staff does not need to continue pressing the pressing rod downward, thereby reducing the difficulty of operation for the staff.

[0019] Furthermore, a rubber sheet is installed on the side wall of the limiting rod close to the stabilizing rod.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. In this application, when the staff needs to test the current sensor, they need to place multiple current sensors on the current sensor fixing seat and pass the copper busbar through the multiple current sensors. Furthermore, the staff needs to lift the pressing rod upward to move the pressing head downward and press against the copper busbar, and activate the limit assembly to keep the pressing rod stable under the action of the limit assembly, eliminating the need for the staff to continuously apply upward force to the pressing rod, thereby facilitating the staff to test the current sensor.

[0022] 2. In this application, when the staff member lifts the pressing rod upward, the slide bar moves upward under the action of the pressing rod, causing the first limit slot to gradually approach and eventually face the second limit slot. The staff member then slides the sliding block, which connects the limit bar with the first limit slot under the action of the sliding block, thereby causing the limit bar to limit the slide bar, thereby keeping the pressing rod stable, without the staff member having to continuously apply upward force to the pressing rod;

[0023] 3. In the present application, when the staff slides the sliding block, the annular thread piece moves with the limiting rod and finally presses against the thread groove. At this time, the limiting rod and the first limiting groove are connected to each other. The staff only needs to rotate the annular thread piece to connect the annular thread piece and the thread groove to each other, so that the limiting rod remains stable, thereby reducing the probability of the limiting rod and the first limiting groove being separated from each other at this time.

[0030] 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.

[0031] like Figure 1-5 As shown, an embodiment of the present application discloses a current sensor testing device, comprising a base plate 1, a current sensor fixing seat 11, a wiring copper block 2, a copper busbar 21, a mounting block 3, a pressing rod 4, a pressing head 41, a telescopic rod 5, a limiting assembly 6, a moving block 71, a connecting spring 8, an annular block 82, an annular threaded piece 83, an iron rod 85 and a magnet block 86. The current sensor fixing seat 11 is mounted on the base plate 1, the wiring copper block 2 is arranged on the current sensor fixing seat 11, and the copper busbar 21 is arranged on the wiring copper block 2. The mounting block 3 is a block-shaped structure, and a plurality of mounting blocks 3 are provided and distributed in sequence on the upper surface of the base plate 1. A rotating groove 31 is provided on the upper surface of the mounting block 3, and the pressing rod 4 is a rod-shaped structure, and the pressing rod 4 is rotatably arranged in the rotating groove 31. The pressing head 41 is a block-shaped structure, and the pressing head 41 is fixed to the bottom surface of the pressing rod 4.

[0032] The telescopic rod 5 is connected to the bottom surface of the pressing rod 4 and includes a sliding rod 51 and a sleeve rod 52. The sliding rod 51 is a rectangular rod-shaped structure that is rotatably mounted on the bottom surface of the pressing rod 4. The sleeve rod 52 is a rectangular rod-shaped structure with an open top. The sleeve rod 52 is slidably connected to the sliding rod 51, and the bottom surface of the sleeve rod 52 is fixed to the upper surface of the base plate 1.

[0033] A first limiting groove 53 is defined on the side wall of the slide rod 51, and a second limiting groove 54 is defined through the side wall of the sleeve rod 52. A limiting assembly 6 is provided on the base plate 1 to limit the position of the telescopic rod 5. The limiting assembly 6 comprises a limiting rod 61 and a sliding block 62. The limiting rod 61 is a round rod slidably disposed within the second limiting groove 54. The sliding block 62 is a block shaped structure fixed to the end of the limiting rod 61.

[0034] When the staff member lifts the pressing rod 4 upward, the slide bar 51 moves upward under the action of the pressing rod 4, so that the first limiting groove 53 gradually approaches and eventually faces the second limiting groove 54. The staff member then slides the sliding block 62, which connects the limiting rod 61 with the first limiting groove 53 under the action of the sliding block 62, thereby causing the limiting rod 61 to limit the slide bar 51, thereby keeping the pressing rod 4 stable, without the staff member having to continuously apply upward force to the pressing rod 4.

[0035] A sliding groove 7 is defined on the side wall of the limiting rod 61 . The moving block 71 is a block-shaped structure. The moving block 71 is fixed on the inner wall of the second limiting groove 54 , and the moving block 71 is slidably connected to the sliding groove 7 .

[0036] The moving block 71 reduces the probability of the limiting rod 61 and the second limiting groove 54 being separated from each other, thereby improving the stability of the device and enhancing the user experience of the staff.

[0037] The annular block 82 is a block structure, and the annular block 82 is rotatably arranged on the side wall of the limiting rod 61. The inner wall of the annular thread piece 83 is connected to the annular block 82, and the side wall of the sleeve rod 52 is provided with a thread groove 84 that matches the annular thread piece 83.

[0038] When the staff slides the sliding block 62, the annular thread piece 83 moves with the limiting rod 61 and finally presses against the thread groove 84. At this time, the limiting rod 61 and the first limiting groove 53 are connected to each other. The staff only needs to rotate the annular thread piece 83 to connect the annular thread piece 83 and the thread groove 84 to each other, so that the limiting rod 61 remains stable, thereby reducing the probability of the limiting rod 61 and the first limiting groove 53 separating from each other at this time.

[0039] One end of the connecting spring 8 is fixed on the inner wall of the first limiting groove 53 away from the second limiting groove 54. The stabilizing rod 81 is a rod-shaped structure. The stabilizing rod 81 and the other end of the connecting spring 8 are fixed to each other. The sliding groove 7 of the stabilizing rod 81 is set in the first limiting groove 53, and the side wall of the stabilizing rod 81 away from the connecting spring 8 is flush with the side wall of the sliding rod 51.

[0040] When the staff separates the annular thread piece 83 and the thread groove 84 from each other, the limit rod 61 is separated from the first limit groove 53 under the action of the stabilizing rod 81 and the connecting spring 8, thereby reducing the probability of the limit rod 61 interfering with the movement of the sliding rod 51 at this time, thereby improving the staff's user experience.

[0041] The iron rod 85 is a round rod-shaped structure, and the iron rod 85 is fixed to the bottom surface of the pressing rod 4. The magnet block 86 is a block-shaped structure, and the magnet block 86 is fixed to the upper surface of the bottom plate 1.

[0042] When the current sensor detection is completed, the staff needs to press the pressing rod 4 downward. At this time, the iron rod 85 and the magnet block 86 are attracted to each other, thereby keeping the pressing rod 4 stable. The staff does not need to continue to press the pressing rod 4 downward, thereby reducing the difficulty of operation for the staff.

[0043] In order to improve the user experience of the staff, a rubber sheet 9 is installed on the side wall of the limiting rod 61 close to the stabilizing rod 81.

[0044] The operating principle of a current sensor testing device in this embodiment is as follows: when a worker needs to test a current sensor, the worker needs to place multiple current sensors on the current sensor fixing seat 11 and pass the copper busbar 21 through the multiple current sensors. Furthermore, the worker needs to lift the pressing rod 4 upward, so that the pressing head 41 moves downward and presses against the copper busbar 21, and activate the limit assembly 6, so that the pressing rod 4 remains stable under the action of the limit assembly 6, eliminating the need for the worker to continuously apply upward force to the pressing rod 4, thereby facilitating the worker's testing of the current sensor.

[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
