[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention. Example 1

[0021] Please see Figures 1 to 8 A portable intelligent fiber optic cable finder, comprising: The signal finder 1 has a macro-bend groove 3 on its upper part. A detection sensor is installed inside the macro-bend groove 3. This sensor is used to accurately detect the optical fiber signal and ensure that the target optical fiber can be accurately found even in complex environments. The detection sensor inside the macro-bend groove 3 can be an NF8508 optical fiber sensor or a SICK WLL180T-P432 optical fiber sensor.

[0022] Signal generator 2, with an optical fiber connector 4 installed on top of it, is used for connecting and fixing optical fibers to ensure reliable connection and stability of signal transmission. The storage plate 5 plays an important role in storage and protection in the whole device. Its two sides are used to store the signal finder 1 and the signal generator 2 respectively. The outer side of the storage plate 5 is equipped with straps 6 for binding and fixing the signal finder 1 to the storage plate 5 and the signal generator 2 to the storage plate 5, so as to ensure that the device will not fall apart during the carrying process. When the signal finder 1 and the signal generator 2 are stored in the storage plate 5, the side of the signal finder 1 and the signal generator 2 with the screen and buttons faces the storage plate 5. This can effectively protect the screen and buttons and prevent them from being scratched or bumped during storage.

[0023] Furthermore, a storage slot 9 is provided on one side of the storage plate 5, and the signal finder 1 is placed inside the storage slot 9. A first protective pad 10 is fixedly connected to the inner edge of the storage slot 9. The first protective pad 10 is made of a soft and elastic material, and the thickness of the first protective pad 10 is greater than the thickness of the button protrusion on the surface of the signal finder 1. It can provide good protection for the button when storing it and prevent the button from being damaged by squeezing.

[0024] Furthermore, the signal finder 1 is provided with anti-slip strips 27 on the outside to increase the friction between the hand and the device, making it easier for the user to hold and operate. Anti-slip pads 11 are fixedly connected to both sides of the inner wall of the storage slot 9. The anti-slip pads 11 are made of a material with a high coefficient of friction, which further enhances the stability of the signal finder 1 in the storage slot 9. Limiting springs 12 are also embedded on both sides inside the storage slot 9. The signal finder 1 has an arc-shaped groove 28 on the outside that cooperates with the limiting springs 12. When the signal finder 1 is placed inside the storage slot 9 for storage, the limiting springs 12 and the arc-shaped groove 28 engage to ensure that the signal finder 1 will not easily slip out.

[0025] Specifically, movable cavities are provided in the middle of both sides of the inner wall of the storage slot 9. The limiting spring 12 is located inside the movable cavity. A pick-and-place slot 31 is provided on the outer side of the storage plate 5 at a position corresponding to the limiting spring 12. The pick-and-place slot 31 is connected to the movable cavity. One end of the limiting spring 12 can extend to the outer side of the storage plate 5 through the pick-and-place slot 31. This design facilitates the maintenance and replacement of the limiting spring 12 when needed.

[0026] Specifically, on the other side of the storage plate 5, at the two corners of the same end, there are fixed plugs 13. The signal generator 2 has a socket at the position corresponding to the plug 13. The signal generator 2 is connected to the plug 13 through the socket to achieve quick and accurate positioning and fixation. A second protective pad 14 is fixedly connected to the edge of the other side of the storage plate 5. The second protective pad 14 is also made of soft material. The thickness of the second protective pad 14 is greater than the thickness of the button protrusion on the surface of the signal generator 2, so as to protect the button of the signal generator 2.

[0027] Furthermore, the bottom of the storage board 5 is also equipped with a spiral rope 7 and a wrist strap 8. The wrist strap 8 is fixedly connected to one end of the spiral rope 7, and the other end of the spiral rope 7 is connected to the storage board 5. The wrist strap 8 is made of a comfortable and breathable material. Users can put their wrist through the wrist strap 8 and carry the device conveniently through the elasticity of the spiral rope 7, while preventing the device from falling accidentally.

[0028] In use, the signal generator 2 is connected and secured to the optical fiber to be detected via its fiber optic connector 4, ensuring a stable connection for subsequent signal transmission and locating operations. The signal generator 2 is then activated to emit a specific signal to the connected optical fiber. The signal locator 1 is held in hand, and the detection sensor inside its upper macro-bend groove 3 is used to detect the area where the optical fiber line needs to be located. The location of the optical fiber line is determined by receiving the signal emitted by the signal generator 2 through the detection sensor.

[0029] When the device is not in use and needs to be stored, the signal finder 1 is stored as follows: Place the signal finder 1 with the side containing the screen and buttons facing the storage plate 5 into the storage slot 9 on one side of the storage plate 5. During placement, the anti-slip strip 27 on the outside of the signal finder 1 engages with the anti-slip pads 11 on both sides of the inner wall of the storage slot 9 to increase friction and prevent slippage. As the signal finder 1 is placed into the storage slot 9, the limiting springs 12 embedded on both sides inside the storage slot 9 will engage with the arc-shaped grooves 28 on the outside of the signal finder 1, securing the signal finder 1 within the storage slot 9.

[0030] Store the signal generator 2: With the side of the signal generator 2 with the screen and buttons facing the storage plate 5, align the two end posts 13 on the other side of the storage plate 5 with the corresponding holes on the signal generator 2 and plug them in to fix the signal generator 2 on the storage plate 5.

[0031] Using the straps 6 on the outside of the storage plate 5, the stored signal finder 1 and signal generator 2 are tied and fixed to the storage plate 5 to complete the storage of the entire device. The spiral rope 7 and wrist strap 8 make it easy to carry and store. Example 2

[0032] The portable intelligent fiber optic cable finder provided in Embodiment 1 has been further optimized, specifically, as follows: Figures 6-7 As shown, a protective soft sleeve 15 is also provided on the upper end of the storage plate 5. The protective soft sleeve 15 is fitted over the top outer side of the signal finder 1 and the signal generator 2, providing additional protection for the top of the equipment. Anti-collision soft pads 16 are fixedly connected to the four corners of the top of the protective soft sleeve 15. The anti-collision soft pads 16 are made of soft and elastic material, which can effectively buffer the impact force when the equipment is hit, protecting the precision components inside the equipment. Extension pieces 17 are fixedly connected to both sides of the protective soft sleeve 15. When the straps 6 are used to bind and fix the storage plate 5, the signal finder 1, and the signal generator 2, the extension pieces 17 are located inside the straps 6, enhancing the stability of the binding. Both ends of the protective soft sleeve 15 are provided with limiting grooves 19, and the upper outer side of the storage plate 5 is fixedly connected with a limiting protrusion 18. The protective soft sleeve 15 achieves connection and limitation with the storage plate 5 through the cooperation of the limiting protrusion 18 and the limiting groove 19, ensuring that the protective soft sleeve 15 will not move arbitrarily on the storage plate 5.

[0033] The above structural design further enhances the safety and stability of the equipment during transport, effectively preventing damage caused by collisions or shaking. Example 3

[0034] The portable intelligent fiber optic cable finder provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 8 As shown, a connecting groove 20 is provided at the bottom of the storage plate 5. A limiting buckle 21 is fixedly connected inside the connecting groove 20. A limiting buckle frame 22 is fixedly connected to one end of the spiral rope 7 that is connected to the storage plate 5. The limiting buckle frame 22 is fastened to the limiting buckle 21 to achieve a reliable connection between the spiral rope 7 and the storage plate 5. The connection method is simple and easy to operate, making it convenient for users to disassemble and install the spiral rope 7 as needed.

[0035] Furthermore, an anti-detachment baffle 23 is provided at the lower end of the connecting groove 20 to block the connecting groove 20 and prevent dust, debris, etc. from entering the interior of the connecting groove 20 and affecting the normal use of the limiting buckle 21 and the limiting buckle frame 22. One end of the anti-detachment baffle 23 is fixedly connected to a pin 24, and the anti-detachment baffle 23 is connected to the storage plate 5 by the pin 24. The other end of the pin 24 is fixedly connected to the storage plate 5 by a fixing screw 26 to ensure that the anti-detachment baffle 23 is firmly installed. A threading groove 25 is also provided on the anti-detachment baffle 23, and the spiral rope 7 is located inside the threading groove 25. The design of the threading groove 25 can better fix the spiral rope 7 and prevent it from shaking during carrying.

[0036] The above structural design optimizes the connection between the spiral rope 7 and the storage plate 5, improving the reliability and stability of the connection. It also makes it easier for users to maintain and replace the spiral rope 7, further enhancing the ease of use and durability of the equipment.
