Description

Technical Field

[0001] This utility model relates to the field of waterproof and dustproof current sensor technology, and in particular to an integrated waterproof and dustproof current sensor. Background Technology

[0002] Current sensors are devices that detect and measure the magnitude of current in a circuit. By monitoring the current, they provide data support for the safe operation of the system and have functions such as circuit protection, current performance monitoring, and high and low voltage isolation. They are widely used in the automotive, industrial automation, and renewable energy fields.

[0003] In many practical applications, such as outdoor and industrial sites, current sensors are susceptible to water and dust. Water can cause short circuits, directly leading to circuit failures, causing the sensor to stop working or output abnormal signals. Dust accumulation can affect heat dissipation and performance, increasing the probability of failure and thus reducing reliability and stability.

[0004] Therefore, it is necessary to provide a new integrated waterproof and dustproof current sensor to solve the above-mentioned technical problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0020] Please see Figures 1 to 3 An integrated waterproof and dustproof current sensor is disclosed, comprising a main protective cover 1 and a secondary protective cover 2. The main protective cover 1 and the secondary protective cover 2 cooperate with each other in the overall structure to form a protective shell for the internal components. Movable slots 3 are provided inside the four corners on the opposite side of the main protective cover 1 and the secondary protective cover 2. These movable slots 3 provide precise installation and positioning space for subsequent connecting components, making the connection between components more regular and orderly. The main protective cover 1 and the secondary protective cover 2 are connected by a tightening assembly, which includes four bolts 4. The outer surfaces of the four bolts 4 are slidably connected to the four corners of the main protective cover 1 and the secondary protective cover 2. This sliding connection ensures that the bolts 4 can be smoothly positioned during installation and provides flexibility for subsequent tightening operations. A nut 5 is threaded onto the outer side of the bolt 4 closest to the main protective cover 1. The threaded engagement between the nut 5 and the bolt 4 ensures a tight connection between the main protective cover 1 and the secondary protective cover 2. The outer surface of the bolt 4 furthest from the main protective cover 1 contacts the inner wall of a movable groove 3 on the side of the secondary protective cover 2. This contact ensures the stability of the bolt 4's position on the secondary protective cover 2, preventing displacement during installation and use. The outer surface of the nut 5 contacts the inner wall of the movable groove 3 on one side of the main protective cover 1, allowing the nut 5 to be evenly stressed during tightening, ensuring a secure connection. Sealing grooves 6 are provided on the adjacent sides of both the main protective cover 1 and the secondary protective cover 2. These sealing grooves 6 are key structures for achieving waterproof and dustproof functions. They provide a precise installation position for the sealing gasket 11 to ensure a sealing effect. Fitting grooves 7 are also provided on the adjacent sides of both the main protective cover 1 and the secondary protective cover 2. Hall current sensors 8 are fitted into the inner walls of the two fitting grooves 7. The size and shape of the fitting grooves 7 are precisely designed to perfectly fit the shape of the Hall current sensor 8, securely fixing the Hall current sensor 8 and laying the foundation for subsequent sealing operations. A terminal 9 is located at the bottom of the Hall current sensor 8 near the secondary protective cover 2. The terminal 9 is used for electrical connection between the sensor and external circuitry and is a key interface for signal transmission. Both the main protective cover 1 and the secondary protective cover 2 have a central hole 10 in their center. The central hole 10 provides a passage for the conductor carrying the measured current, and its design ensures smooth and stable passage. A sealing gasket 11 is fitted over the Hall current sensor 8. The sealing gasket 11 is made of a special sealing material and has good flexibility and sealing performance. Multiple bolts 4 are connected to the sealing gasket 11. The four corners are internally connected by a sliding connection. This connection method allows the sealing gasket 11 to work in conjunction with the bolt 4 during installation, ensuring the overall structure's sealing performance. The sealing gasket 11 and the two sealing grooves 6 are connected by a fitting, further enhancing the sealing effect and effectively preventing the intrusion of water and dust. The inner diameter of the sealing gasket 11 is slightly larger than the outer diameter of the Hall current sensor 8, and the outer diameter of the Hall current sensor 8 is slightly smaller than the inner diameter of the fitting groove 7. This slight difference in size design ensures that the Hall current sensor 8 can be smoothly installed in the fitting groove 7, and also ensures that the sealing gasket 11 can fit tightly between the sensor and the protective cover. The shielding assembly is installed on the side of the secondary protective cover 2 away from the main protective cover 1. The shielding assembly includes an extension tube 12, one side of which is fixedly connected to the bottom end of the side of the secondary protective cover 2 away from the main protective cover 1. The length and diameter of the extension tube 12 are carefully designed to effectively block water and dust from the side from approaching the terminal 9. A shielding frame 14 is fixedly connected to the side of the extension tube 12 away from the secondary protective cover 2. The shielding frame 14 provides a wider range of protection against external water and dust, expanding the protection area. An inclined shielding plate 13 is fixedly connected to the top of the extension tube 12. The inclined angle of the inclined shielding plate 13 is optimized to effectively prevent water and dust from directly falling onto the terminal 9. The bottom end of the inclined shielding plate 13 is fixedly connected to the top end of the shielding frame 14, so that the shielding assembly forms a stable and continuous protective structure, enhancing the overall waterproof and dustproof performance.

[0021] The working principle of the integrated waterproof and dustproof current sensor provided by this utility model is as follows: When installing the Hall current sensor 8 between the main protective cover 1 and the secondary protective cover 2, first, one side of the Hall current sensor 8 is fitted into the fitting groove 7 that contacts the main protective cover 1. Then, the sealing gasket 11 is fitted onto the outside of the Hall current sensor 8 and fits into the sealing groove 6 on the main protective cover 1. Before fitting the sealing gasket 11 into the sealing groove 6 of the main protective cover 1, a thin layer of waterproof sealant is applied to the edge of the sealing groove 6 to enhance the sealing performance between the sealing gasket 11 and the sealing groove 6, further preventing water and dust from entering. Then, the wiring is passed through the extension tube 12, the inclined shield 13, the shield frame 14, and connected to the terminal 9. The extension tube 12 prevents water and dust from approaching the terminal 9 from the side, the inclined shield 13 prevents water and dust from falling directly onto the terminal 9, and the shield frame... 14. It acts as a shield against external water and dust. After the connection is completed, the secondary protective cover 2 is moved to fit the matching groove 7 on the other side of the Hall current sensor 8. At this time, the sealing groove 6 on the secondary protective cover 2 also fits with the other side of the sealing gasket 11. At this time, the main protective cover 1 and the secondary protective cover 2 cover the Hall current sensor 8, forming a sealed protection for the sensor. The sealing gasket 11 is installed between the two. Then, the bolt 4 passes through the movable groove 3 at the four corners of the main protective cover 1 and the secondary protective cover 2 and is connected to the nut 5. In this process, it also passes through the four corners of the sealing gasket 11. Then, the nut 5 is tightened to complete the installation of the main protective cover 1 and the secondary protective cover 2, and further tighten it to ensure that the sealing structure is tight and prevent water and dust from entering from the connection part of the protective cover.
