[0030] 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.

[0031] The core of this utility model is to provide a hovering protective cover structure. When the mating part of the protective cover is engaged in the hovering groove, the protective cover opens and hovers stably and reliably in the first hovering position.

[0032] In addition, this utility model also provides a through-wall terminal including the above-mentioned suspended protective cover structure.

[0033] The suspended protective cover structure provided by this utility model includes a protective cover 10 and a housing 20. The protective cover 10 and the housing 20 are rotatably connected by a rotating shaft 11. The protective cover 10 is provided with a mating part 12 below the rotating shaft 11. The side of the housing 20 is provided with a rotating shaft mounting hole 21 for mounting the rotating shaft 11 and a suspension groove 22 for engaging with the mating part 12. When the mating part 12 of the protective cover 10 is engaged in the suspension groove 22, the protective cover 10 is opened and suspended in the first suspension position.

[0034] The protective cover 10 and the housing 20 together form the outer shell structure of the through-wall terminal. Both the protective cover 10 and the housing 20 are made of insulating materials. For example, the protective cover 10 is usually set as a plastic protective cover. The specific materials and dimensions of the two are determined according to the actual production needs and with reference to the through-wall terminals in the prior art, and will not be elaborated here.

[0035] The protective cover 10 and the housing 20 are rotatably connected by a pivot 11. During their mutual rotation, the mating part 12 of the protective cover 10 can rotate around the pivot 11. After the protective cover 10 rotates to a specific position, it is engaged in the suspension groove 22 of the housing 20. The engagement between the mating part 12 and the suspension groove 22 allows the protective cover 10 to be suspended at a specific position. It should be noted that the specific position here refers to the pitch angle of the vertical plane on which the protective cover 10 is located relative to the side of the housing 20, or the approximately parallel vertical plane.

[0036] Therefore, the length of the line connecting the center of the mating part 12 corresponding to the hovering groove 22 of the housing 20 to the center of the rotating shaft mounting hole 21 is equal to the length of the line connecting the center of the mating part 12 on the protective cover 10 to the center of the rotating shaft 11.

[0037] The specific value of the pitch angle of the protective cover 10 corresponding to the first hover position is determined according to the user's opening and closing requirements for the protective cover 10 in actual production, and will not be elaborated here.

[0038] In this embodiment, the side of the housing 20 is provided with a hovering groove 22 for engaging with the mating part 12 of the protective cover 10. When the mating part 12 of the protective cover 10 is engaged in the hovering groove 22, the protective cover 10 opens and hovers in the first hovering position. The engagement between the two is stable and reliable, preventing the protective cover 10 from accidentally closing and causing accidental injury to maintenance personnel. Moreover, the above-mentioned engagement structure is not sensitive to wear and can still maintain a large hovering ability after multiple openings and closings, significantly reducing the possibility of misoperation.

[0039] Based on the above embodiments, in order to meet different hovering needs of users, the hovering groove 22 includes a first mating position and a second mating position. When the mating part 12 is engaged in the first mating position, the protective cover 10 opens and hovers in the first hovering position. When the mating part 12 is engaged in the second mating position, the protective cover 10 opens and hovers in the second hovering position.

[0040] The hovering groove 22 is provided with at least two mating positions 221, which correspond to different hovering positions of the protective cover 10. The structure and size of the mating position 221 need to correspond to the structure and size of the mating part 12.

[0041] In order to ensure that the mating part 12 can be stably engaged with each mating position 221 of the hovering groove 22, and to prevent the mating part 12 from sliding between two adjacent mating positions 221 of the hovering groove 22 when it is not under force or only under slight external force, preferably, a separating position 222 is provided between the first mating position and the second mating position. The separating position 222 is used to limit the sliding of the mating part 12 in the hovering groove 22.

[0042] The separator 222 can specifically be an arc-shaped groove between two adjacent mating positions 221, with both ends of the arc-shaped groove higher than the endpoints of the adjacent mating positions 221; or it can be a convex groove, with both ends of the convex groove higher than the endpoints of the adjacent mating positions 221, such as... Figure 5 As shown, this is to enhance the limiting effect of the separator 222 on the mating position 221.

[0043] The more mating positions 221 there are within the hovering groove 22, the larger the overall size of the hovering groove 22 will be, and the greater the impact on the strength of the side wall of the housing 20, assuming the structure and size of the mating part 12 remain unchanged. Therefore, the total number of mating positions 221 within the hovering groove 22 should not be excessive. For example... Figure 5 The central suspension groove 22 has three mating positions 221.

[0044] Based on the above embodiments, the structure of the mating part 12 of the protective cover 10 is defined. The mating part 12 includes a cylindrical mating part that protrudes from the side wall of the protective cover 10. The length of the protective cover 10 is less than the length of the housing 20. The hovering groove 22 includes at least one arc-shaped groove.

[0045] Compared to setting the mating part 12 as a prism structure, setting the mating part 12 as a cylindrical structure not only helps to reduce the thrust required to move the mating part 12 between different mating positions 221 of the hovering groove 22, but also facilitates the processing and manufacturing of the hovering groove 22.

[0046] Preferably, in order to ensure that the cylindrical mating part can be stably and reliably engaged at a certain mating position 221, an elastic layer can be provided on the outer peripheral surface of the cylindrical mating part. The elastic layer is used to increase the friction between the cylindrical mating part and the suspension groove 22.

[0047] The elastic layer can be specifically set as an elastic rubber layer, etc. Of course, the elastic layer can also be replaced with a structure with similar functions, such as anti-slip texture.

[0048] Based on the above embodiments, the structure of the rotating shaft 11 of the protective cover 10 is defined. The rotating shaft 11 includes a rotating shaft portion that protrudes from the side wall of the protective cover 10 and is rotatably fitted into the rotating shaft mounting hole 21 of the housing 20.

[0049] Compared to the rotating shaft mounting holes 21 that pass through both ends of the housing 20 via the same rotating shaft 11, using rotating shafts on both sides to rotatably connect to both ends of the housing 20 not only facilitates the installation of the rotating shaft 11 and simplifies the assembly process of the protective cover 10 and the housing 20, but also improves the stability and reliability of the rotatable connection between the protective cover 10 and the housing 20.

[0050] For preferred options, please refer to [the provided text]. Figure 5 The side wall of the housing 20 includes a mounting area protruding from the back of the housing 20. The pivot mounting hole 21 and the hovering groove 22 are both located in the mounting area of ​​the side wall, and the pivot mounting hole 21 is connected to the end of the mounting area that is relatively far away from the back of the housing 20.

[0051] The shaft mounting hole 21 adopts an open design, which is more conducive to the assembly process of the protective cover 10 and the housing 20 compared to the closed structure of the shaft mounting hole 21, and also helps to reduce the weight of the housing 20.

[0052] Based on the above embodiments, in order to prevent the rotating shaft 11 from coming out of the open rotating shaft mounting hole 21, at least one protrusion can be provided on the outer periphery of the rotating shaft 11. The protrusion is used to increase the difficulty for the protective cover 10 to detach from the housing 20.

[0053] In this embodiment, by increasing the difficulty of assembling and disassembling the protective cover 10 and improving the stability and reliability of the rotational connection between the protective cover 10 and the housing 20, the protective cover 10 is prevented from being accidentally pulled away from the housing 20. At the same time, the protrusion helps to increase the strength of the rotating shaft 11, preventing excessive force from rotating the protective cover 10, which could damage the rotating shaft 11 or cause the entire protective cover 10 to be pulled away from the housing 20.

[0054] In addition to the above-mentioned through-wall terminal, this utility model also provides a through-wall terminal including the suspended protective cover structure disclosed in the above embodiments. For the structure of other parts of the through-wall terminal, please refer to the prior art.

[0055] Please refer to Figure 8 The housing 20 of the through-wall terminal is provided with several baffles 30 evenly arranged along the length direction. Copper busbars 40 are provided between two adjacent baffles 30 or between the baffles 30 and the inner wall of the housing 20. The specific number, specifications, distribution and installation method of the copper busbars 40 are determined according to the design function of the through-wall terminal in actual production, and will not be elaborated here.

[0056] It should be noted that the first hover position and the second hover position, as well as the first mating position and the second mating position in this application, are only used to distinguish the different positions and do not contain any limitation on the order.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The wall-penetrating terminal and suspended protective cover structure provided by this utility model have been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
