[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a smart terminal for a distribution area, including a terminal housing 1, which serves as the basic supporting structure of the terminal. The terminal housing 1 is the mounting carrier for all functional modules and electronic components, providing physical protection for core components such as internal circuits, chips, and sensors, and isolating them from direct contact with external dust and impurities. A protective mechanism 2 is fixedly connected to the wiring terminal of the terminal housing 1, achieving all-round protection of the wiring terminal through the collaboration of multiple components. A connecting mechanism 3 is provided on the outside of the protective mechanism 2. The protective mechanism 2 includes a base 21, which is fixedly installed on the lower part of the wiring terminal of the terminal housing 1 by bolts. The base 21 is rigidly connected to the lower part of the wiring terminal of the terminal housing 1 by bolts, ensuring that the protective mechanism 2 is installed stably and preventing displacement due to vibration or external force in outdoor environments. A rotating part 22 is rotatably connected to the right side of the base 21, forming an openable and closable structure of the protective mechanism 2. The opening and closing states can be switched to meet various needs. To meet the needs of wiring, maintenance, and other operations, a sealed cavity is formed when closed. The inner walls of the opposite ends of the base 21 and the rotating part 22 are provided with mounting grooves 23, providing dedicated installation space for the sealing plates a24 and b25. The groove structure restricts the installation position of the sealing plates a24 and b25, ensuring precise alignment. The inner wall of the mounting groove 23 of the base 21 is fitted with the sealing plate a24, and the inner wall of the mounting groove 23 of the rotating part 22 is fitted with the sealing plate b25. The sealing plates a24 and b25 are the main carriers for moisture-proof sealing. The opposite side of the sealing plates a24 and b25 is provided with a wire positioning groove 26, which adapts to the shape of the cable and can fit tightly against the surface of the cable, reducing the gap between the cable and the sealing plates a24 and b25, and providing an installation base for the sealing element 27. The inner wall of the wire positioning groove 26 is fixedly connected to the sealing element 27.

[0026] Reference Figure 2 , Figure 4 and Figure 5A connecting protrusion 5 is fixedly connected to the lower part of the sealing plate b25. A connecting slot 6 is provided in the middle part of the upper part of the sealing plate a24. The connecting protrusion 5 and the connecting slot 6 are inserted and matched. The lower part of the connecting protrusion 5 is designed as an isosceles trapezoid, which forms a longitudinal sealing seam when closed, preventing humid air from seeping in from the joint between the sealing plate a24 and the sealing plate b25. The isosceles trapezoidal design of the connecting protrusion 5 can guide the insertion and positioning, improving the accuracy of the joint between the sealing plate a24 and the sealing plate b25 and the tightness of the seal. The inner wall of the mounting groove 23 is horizontally provided with an arc-shaped protrusion to form a mechanical limit seal, preventing the sealing plates a24 and b25 from loosening or shifting when the equipment is vibrating or touched by external force, ensuring the stability of the sealing structure. The outer sides of the sealing plates a24 and b25 are opened A slot 4 is provided, which engages with the arc-shaped protrusion on the inner wall of the mounting groove 23. A rubber pad is provided on the rear side of the base 21 and the rotating part 22 to fill the gap between the base 21 and the terminal housing 1, forming a secondary seal and preventing humid air from seeping in from the connection gap between the base 21 and the terminal housing 1. The cable position groove 26 is semi-circular, and the sealing element 27 is made of rubber. The width of the left and right sides of the sealing element 27 is wider than that of the middle part of the sealing element 27. When the cable passes through the cable position groove 26, the sealing element 27 can conform to the surface of the cable through its own elastic deformation, filling the tiny gap between the cable and the cable position groove 26. The structure design of being narrow in the middle and wide on both sides can enhance the contact area between the sealing element 27 and the cable and the inner wall of the cable position groove 26, increase the sealing pressure, and effectively prevent humid air and rainwater from seeping into the terminal from the cable gap.

[0027] Reference Figure 1 - Figure 3 The connecting mechanism 3 includes an operating lever 31. A baffle 32 is fixedly connected to the outer side of the operating lever 31. The baffle 32 serves as the mounting carrier for the permanent magnet 33. The permanent magnet 33, which is fixedly connected to the rear side of the baffle 32, achieves magnetic attraction with the iron plate 34 on the rotating part 22. The operating lever 31 is inserted into the inner left side of the base 21 and the rotating part 22. An iron plate 34 is fixedly connected to the outer front part of the rotating part 22 near the operating lever 31. A permanent magnet 33 is fixedly connected to the rear side of the baffle 32. The permanent magnet 33 generates a magnetic attraction force with the iron plate 34 of the rotating part 22 through its own magnetism, tightly attracting and fixing the rotating part 22 and the base 21. The iron plate 34 and the permanent magnet 33 are magnetically attracted. The operating lever 31 is T-shaped, which is convenient for maintenance personnel to hold and operate. As the operating actuator of the connecting mechanism 3, the fixed state of the rotating part 22 and the base 21 can be switched by the insertion and removal action.

[0028] Working principle: When connecting cables, the maintenance personnel first hold the T-shaped operating lever 31 and pull it outward, which drives the baffle 32 and the permanent magnet 33 on the back of the baffle 32 to move synchronously, so that the permanent magnet 33 and the iron plate 34 on the outside of the rotating part 22 are disengaged from the magnetic attraction, and the fixed restriction of the rotating part 22 is released. Then, with the rotating connection point on the right side of the base 21 as the axis, the rotating part 22 is flipped up to expose the wiring port of the terminal housing 1. After connecting the external cable to the wiring terminal of the terminal housing 1, the cable is combed to fit the semi-circular wire position groove 26 of the sealing rubber plate a24 on the base 21.

[0029] The rotating part 22 is flipped downwards to close with the base 21. During this process, the isosceles trapezoidal connecting protrusion 5 at the lower part of the sealing plate b25 on the rotating part 22 is precisely inserted into the connecting slot 6 of the sealing plate a24 on the base 21 under the guiding action, forming a longitudinal sealing seam. At the same time, the rubber sealing element 27 on the inner wall of the wire position groove 26 on the sealing plate a24 and the sealing plate b25 undergoes elastic deformation due to the compression of the cable, fully adhering to the surface of the cable and the inner wall of the wire position groove 26, filling the tiny gaps.

[0030] Finally, push the operating lever 31 inward so that it inserts through the left inner wall of the base 21 and the rotating part 22. The permanent magnet 33 on the back of the baffle 32 is attracted and fixed to the iron piece 34 of the rotating part 22, tightly locking the rotating part 22 and the base 21. At this time, the rubber pad on the back of the rotating part 22 and the rubber pad on the back of the base 21 work together to seal, and with the sealing of the sealing plate a24 and the sealing plate b25 and the sealing of the cable by the sealing element 27, it prevents humid air and rainwater from seeping into the interior of the terminal housing 1 from the gaps in the wiring terminal.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
