[0020] 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.

[0021] This utility model embodiment provides a three-axis fluxgate sensor, such as... Figure 1-5As shown, the device includes a fluxgate sensor body 1 and a protection component 2. The fluxgate sensor body 1 includes a housing 11 and a connector 12 located on one side of the housing 11. The protection component 2 includes a mounting block 21 mounted on one side of the housing 11. The mounting block 21 has a socket 211, and the connector 12 is located inside the socket 211. The triaxial fluxgate sensor also includes a protection plate 22. The protection plate 22 can block the socket 211 or be moved away from the socket 211. When the protection plate 22 blocks the socket 211, it can protect the connector 12 and prevent dust and other debris from entering the connector 12 and causing poor contact. At the same time, the front of the protection plate 22 has a driving slope 221. When the plug is inserted into the socket 211, the plug presses against the driving slope 221, driving the protection plate 22 to slide linearly, so that the protection plate 22 is moved away from the socket 211, and the plug can be inserted into the connector 12.

[0022] In this embodiment, the mounting block 21 has a groove 212 on its back that communicates with the insertion hole 211. The protective plate 22 is slidably disposed inside the groove 212. The protective plate 22 can slide linearly inside the groove 212, allowing it to block the insertion hole 211 or move away from the insertion hole 211. Both sides of the groove 212 have L-shaped structures, which can restrict the protective plate 22 within the groove 212, ensuring that the protective plate 22 slides linearly. Additionally, one end of the groove 212 is open, and the other end is... The enclosed structure allows the protective plate 22 to be easily inserted into the slide groove 212. To prevent the protective plate 22 from sliding out of the slide groove 212, a baffle 23 is detachably installed at the open end of the slide groove 212. In this embodiment, the detachable connection structure includes a locking block 231 located on one side of the baffle 23. The locking block 231 has a hemispherical structure, and the slide groove 212 has a locking groove 213 that cooperates with the locking block 231. When installing the baffle 23, both ends of the baffle 23 are opened from the slide groove 212. The baffle 23 is inserted into the two sides of the slide groove 212 respectively, and the baffle 23 is pushed to slide inside the slide groove 212 until the locking block 231 is inserted into the locking groove 213, thus completing the installation of the baffle 23. When removing the baffle 23, push the baffle 23 to make the locking block 231 disengage from the locking groove 213, thus completing the removal of the baffle 23. The installation and removal are convenient. For the detachable connection structure, it only needs to meet the requirement of being able to detachably install the baffle 23 at the opening end of the slide groove 212. Therefore, it is not limited to a specific structure. For example, in some embodiments, the detachable connection structure uses bolts threaded onto the baffle 23. The baffle 23 can be tightened and fixed inside the slide groove 212 by the bolts, which is convenient for installation and removal. In other embodiments, the detachable connection structure uses other structures to install the baffle 23 at the opening end of the slide groove 213. All detachable connection structures that can install the baffle 23 at the opening end of the slide groove 213 are within the protection scope of this utility model.

[0023] In this embodiment, one end of the protection plate 22 is connected to the closed end of the slide groove 212 by an elastic member 24. When the protection plate 22 is removed from the socket 211, the elastic member 24 undergoes elastic deformation. At the same time, the elastic member 23 provides a reset force for the protection plate 22, pressing the protection plate 22 against the plug to prevent the plug from loosening. When the socket is pulled out from the socket 211, the elastic member 24 restores its elastic deformation and provides a reset force for the protection plate 22, causing the protection plate 22 to block the socket 211.

[0024] In this embodiment, the elastic element 23 is a spring. When the elastic element 23 is a spring, a guide rod 222 is provided on one side of the protective plate 22, and a guide hole 214 that cooperates with the guide rod 222 is provided on one side of the slide groove 212. The guide rod 222 is slidably disposed inside the guide hole 214. Through the cooperation between the guide rod 222 and the guide hole 214, the protective plate 22 can slide stably inside the slide groove 212. At the same time, the spring is sleeved on the guide rod 222. One end of the spring contacts one end of the protective plate 22 but is not fixedly connected, and the other end of the spring contacts the closed end of the slide groove 212 but is not fixedly connected, which facilitates disassembly and assembly. For the elastic element 23, it only needs to meet the requirement of providing a reset force for the protective plate 22. Therefore, it is not limited to a specific structure. For example, in some embodiments, the elastic element 23 is a metal spring sheet. In other embodiments, the elastic element 23 is other objects that can provide a reset force for the protective plate 22. All elastic elements 23 that can provide a reset force for the protective plate 22 are within the protection scope of this utility model.

[0025] It should be noted that mounting holes 215 are provided at all four corners of the mounting block 21, which can be conveniently installed on the outer casing 11.

[0026] Specific principle: When the plug is inserted into the socket 211, the plug presses against the driving inclined surface 221, driving the protective plate 22 to slide linearly, so that the protective plate 22 moves away from the socket 211, allowing the plug to be inserted into the connector 12. At the same time, the elastic element 24 undergoes elastic deformation, providing a reset force for the protective plate 22, pressing the protective plate 22 against the plug to prevent the plug from loosening. When the socket is pulled out from the socket 211, the elastic element 24 returns to its elastic deformation and provides a reset force for the protective plate 22, causing the protective plate 22 to block the socket 211. When the protective plate 22 blocks the socket 211, it can protect the connector 12, preventing external dust and other debris from entering the connector 12 and causing poor contact.

[0027] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
