Through these experiments, students can develop their ability to identify, solve, and analyze problems, cultivate their hands-on and innovative abilities, and enhance their interest in learning. Therefore, the comprehensive electrical and electronic experimental workbench is an indispensable part of learning electrical engineering. Non-contact current monitoring devices are important components of the electrical operation experimental workbench.

[0003] Existing non-contact current monitoring devices are not convenient to clamp the wires during use, which makes it easy for the wires to fall out when the device is hit, resulting in incorrect or inaccurate monitoring results and reducing their practicality.

[0004] Based on this, a non-contact current monitoring device for electrical operation test benches is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a non-contact current monitoring device for an electrical operation test bench, so as to solve the problem of inconvenience in clamping and fixing wires.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] like Figures 1-4 As shown, the non-contact current monitoring device for electrical operation test bench includes: a current monitoring device body 1, a current sensor 2 installed on one side inside the current monitoring device body 1, a power cord 3 electrically connected to the outside of the current monitoring device body 1, a clamping mechanism 4 inside the current monitoring device body 1, a sliding component at one end of the power cord 3, an electrical connection plate 6 installed outside the sliding component, and an operating table 5 fixedly installed at the bottom of the electrical connection plate 6.

[0025] In this embodiment, both the main body 1 of the current monitoring device and the current sensor 2 are manufactured using existing mature technologies. The principle is mainly based on the Hall effect, so it will not be described in detail here. The wire to be monitored is placed inside the current sensor 2 through the clamping mechanism 4, which effectively monitors the current of the wire. In the event of a collision, the wire will not leave the inside of the current sensor 2, which improves the stability and accuracy of current monitoring. The sliding component allows the main body 1 of the current monitoring device to be easily moved to a designated position to monitor the wire as needed, which improves its practicality.

[0026] The clamping mechanism 4 includes a gear 41, which is rotatably mounted inside the current monitoring device body 1. A rack 42 is meshed with the outside of the gear 41, and a sliding member 43 is fixedly connected to the outside of the rack 42. Both the rack 42 and the sliding member 43 are slidably mounted to the current monitoring device body 1. Four connecting rods 44 are rotatably mounted on the top and bottom of the sliding member 43. A clamping plate 45 is rotatably mounted between every two connecting rods 44. A reset assembly is provided at one end of the gear 41, including a connecting shaft 46. One end of the connecting shaft 46 is connected to one end of the gear 41, and the other end of the connecting shaft 46 is fixedly connected to a first handle 47. One side of the current monitoring device body 1 is connected to the first handle 47. A positioning groove 48 is provided on one side of the 7. A torsion spring 49 is installed on the outside of the connecting shaft 46 and between the two positioning grooves 48. When the wire needs to be monitored, the first handle 47 is rotated. The first handle 47 drives the gear 41 to rotate through the connecting shaft 46. During this process, the elastic potential energy of the torsion spring 49 increases. The gear 41 drives the sliding member 43 to slide through the rack 42. Due to the cooperation of the connecting rod 44, the two clamps 45 are opened. The wire is placed between the two clamps 45. The first handle 47 is slowly loosened. The torsion spring 49 releases its elastic potential energy, causing the first handle 47 to return to its original position. The two clamps 45 move closer to each other to clamp and fix the wire. Since the clamps 45 are located directly below the current sensor 2, the wire is located inside the current sensor 2.

[0027] The sliding assembly includes a portable power supply base 8, one side of which is electrically connected to one end of the power cord 3. A groove 7 is provided on one side of the electrical connection plate 6, allowing the portable power supply base 8 to slide along the groove 7. A knob 9 is threaded onto one side of the portable power supply base 8. Loosening the knob 9 allows the portable power supply base 8 to slide within the groove 7, facilitating adjustment of the position of the power cord to be monitored and improving practicality.

[0028] A locking mechanism 10 is symmetrically provided on one side of the electrical connection plate 6. When the current monitoring device body 1 is no longer in use, the locking mechanism 10 can be used to fix the current monitoring device body 1 to the electrical connection plate 6. When the current monitoring device body 1 needs to be used, the locking mechanism 10 can be used to separate the current monitoring device body 1 from the electrical connection plate 6, making it easy to store and retrieve.

[0029] The locking mechanism 10 includes a protective shell 101, which is fixedly installed on one side of the electrical connection plate 6. An installation groove 102 is provided inside the protective shell 101, and a first locking block 103 is slidably installed inside the installation groove 102. A limit rod 104 is fixedly connected to one side of the first locking block 103. One end of the limit rod 104 passes through the protective shell 101 and is connected to a second handle 105. A spring 106 is sleeved on the outside of the limit rod 104 and on one side of the first locking block 103. A second locking block 107 is fixedly connected to the other side of the current monitoring device body 1, and the second locking block 107 is compatible with the first locking block 103. When the current monitoring device body 1 needs to be used, the second handle 105 is held by hand. The limiting rod 104 pulls the first locking block 103 out to one end. During this process, the spring 106 is compressed, and the engagement between the first locking block 103 and the second locking block 107 is released. At this time, the main body 1 of the current monitoring device is easy to take out. When the main body 1 of the current monitoring device needs to be stored after use, the second locking block 107 is aligned with the first locking block 103, and the second locking block 107 moves into the mounting groove 102. Since both the first locking block 103 and the second locking block 107 are chamfered, the first locking block 103 moves upward and the spring 106 is compressed. When the second locking block 107 moves to the innermost position, the first locking block 103 and the second locking block 107 are engaged due to the reset action of the spring 106, thus completing the storage of the main body 1 of the current monitoring device.

[0030] Working principle: When the main body 1 of the current monitoring device is needed, the second handle 105 is held and the first locking block 103 is pulled to one end through the limiting rod 104. During this process, the spring 106 is compressed, and the engagement between the first locking block 103 and the second locking block 107 is released. At this time, the main body 1 of the current monitoring device is easy to pick up. The first handle 47 is rotated, and the first handle 47 drives the gear 41 to rotate through the connecting shaft 46. During this process, the elastic potential energy of the torsion spring 49 increases, and the gear 41 drives the sliding part 43 to slide through the rack 42. Due to the cooperation of the connecting rod 44, the two clamps 45 open, allowing the wire to be placed... Placed between the two clamping plates 45, the first handle 47 is slowly loosened. The torsion spring 49 releases its elastic potential energy, causing the first handle 47 to reset. The two clamping plates 45 move closer together to clamp and fix the wire. Since the clamping plates 45 are located directly below the current sensor 2, the wire is located inside the current sensor 2, effectively monitoring the wire current. In the event of a collision, the wire will not leave the inside of the current sensor 2, improving the stability and accuracy of current monitoring. The sliding component allows the main body 1 of the current monitoring device to be easily moved to a designated position to monitor the wire as needed, improving its practicality.
