[0002] The mounting structure of a high-precision current sensor typically refers to a set of mechanical devices used to ensure the stability of the sensor and protect it from external damage. Such a mounting structure is crucial for ensuring the accurate measurement of current sensors in industries, scientific research, and other fields.

[0003] Existing sensor mounting structures typically employ direct external fixing, which often overlooks the physical damage that sensors may suffer during operation and lacks necessary protective measures. Furthermore, due to the rigidity of the fixing method, maintenance or replacement of the sensor is cumbersome and prone to damage to the sensor or mounting structure, which is detrimental to the long-term stable operation and convenient maintenance of the equipment. Therefore, a high-precision current sensor mounting structure is proposed. Utility Model Content

[0025] Example

[0026] Reference Figure 1-6 This is an embodiment of the present invention, which provides a fixing structure for a high-precision current sensor, including:

[0027] The components include a lower cover 101, a placement groove 102 in the center of the lower cover 101, a limiting component 103 in the inner cavity of the lower cover 101, a buffer component 104 used in conjunction with the limiting component 103, a protective component 105 in the center of the placement groove 102, a sensor body 106 placed in the inner cavity of the placement groove 102, and a top cover 107 snapped onto the surface of the lower cover 101.

[0028] The limiting assembly 103 includes a limiting plate 103a, a gear 103b meshing with the limiting plate 103a, a rack 103c meshing with the side surface of the gear 103b, a movable sleeve 103d sleeved on the side surface of the rack 103c, and a base plate 103e fixedly connected to the side surface of the rack 103c.

[0029] The buffer assembly 104 includes a contact plate 104a fixedly connected to the base plate 103e, a contact block 104b inserted into the surface of the contact plate 104a, a rotating rod 104c fixedly connected to the bottom of the contact block 104b, and a support column 104d fixedly installed on the surface of the base plate 103e.

[0030] The buffer assembly 104 also includes a connecting rod 104e fixedly connected to the end of the rotating rod 104c, a contact rod 104f sleeved on the side surface of the connecting rod 104e, and a spring 104g sleeved on the side wall of the contact rod 104f.

[0031] Specifically, the sensor body 106 is placed in the placement slot 102 of the lower cover 101, and the sensor's stable position is ensured by the limiting component 103; the buffer component 104 provides elastic support and cushioning to protect the sensor from external impacts. During installation, the top cover 107 snaps onto the surface of the lower cover 101, completing the overall fixation. When maintenance or sensor replacement is required, the top cover 107 can be easily adjusted and removed by operating the connecting rod 104e and spring 104g in the buffer component 104, enabling convenient disassembly of the sensor.

[0032] The protective component 105 includes a connecting plate 105a, an extrusion groove 105b formed on the surface of the connecting plate 105a, and a slider 105c that contacts the inner surface of the extrusion groove 105b.

[0033] The protective component 105 also includes a telescopic rod 105d fixedly connected to the surface of the slider 105c, and a damping plate 105e in contact with the side surface of the slider 105c. The slider 105c and the telescopic rod 105d are provided on both sides of the damping plate 105e.

[0034] The top cover 107 includes a cover body 107a, a stop block 107b fixedly connected to the bottom of the cover body 107a, and a slot 107c formed on the side surface of the cover body 107a. The stop block 107b is in contact with the contact rod 104f, and the sensor body 106 is in contact with the contact plate 104a and the contact block 104b.

[0035] It should be noted that the sensor body 106 is located in the placement slot 102 of the lower cover 101 and is protected by the protective component 105. The slider 105c slides in the compression groove 105b. The telescopic rod 105d and the damping plate 105e provide additional protection. The top cover 107 is snapped onto the lower cover 101. The abutment 107b contacts the contact rod 104f of the buffer component 104. The sensor body 106 contacts the contact plate 104a and contact block 104b of the buffer component 104. During operation, these components work together to ensure that the sensor is stable and protected. During maintenance, the sensor body 106 can be easily accessed for necessary inspection or replacement by operating the top cover 107 and the buffer component 104.

[0036] In use, the sensor body 106 is placed in the placement slot 102 of the lower cover 101 and precisely positioned by the limiting component 103. Simultaneously, the buffer component 104 provides elastic support to absorb external impacts and protect the sensor from damage. The slider 105c in the protection component 105 slides within the compression groove 105b. The telescopic rod 105d and damping plate 105e further enhance the sensor's protective capabilities. The top cover 107 is connected to the lower cover 101 via the slot 107c, and its abutment 107b contacts the contact rod 104f of the buffer component 104, forming an adjustable fixing system. During maintenance, the top cover 107 can be easily removed by operating the connecting rod 104e and spring 104g of the buffer component 104, enabling convenient maintenance and replacement of the sensor body 106, ensuring long-term stable operation and easy maintenance of the sensor.

[0037] In summary, the stability and safety of the sensor body 106 are ensured through the cooperation between the components. The precise cooperation between the limiting component 103 and the buffer component 104 reduces the impact of vibration and shock on the sensor. The design of the protection component 105 improves the sensor's ability to protect against accidental damage. The snap-fit ​​design of the top cover 107 makes the installation and removal of the sensor more convenient, reduces the complexity and time cost of maintenance, and improves the sensor's environmental adaptability and long-term operational reliability.
