[0029] The implementation details of the technical solution of this utility model embodiment are described in detail below:

[0030] First, it should be noted that the insulating protective device of the fuse 4 provided by this utility model is used to cover the lower end of the fuse 4 (i.e., Figure 3 The circular conductive terminal is shown in the diagram. However, simply covering the circular conductive terminal is insufficient, as the conductive element 43 within the fuse 4 is susceptible to leakage or accidental electric shock from conductive objects such as animals. Therefore, this invention provides comprehensive and effective insulation protection for the fuse 4 by insulating both the circular conductive terminal and the conductive element 43. Furthermore, the insulation protection device provided by this invention is easy to manufacture and has a low production cost.

[0031] According to one aspect of the present invention, an insulation protection device for a fuse is provided. The device includes a semi-circular cover 1, a connecting part 2, and a semi-elliptical cover 3. The semi-circular cover 1 is connected to the connecting part 2, and the connecting part 2 is connected to the semi-elliptical cover 3. The semi-circular cover 1 includes a semi-circular opening 11 that runs from top to bottom, and the semi-circular opening 11 is used to place the lower end of the fuse 4 to provide insulation protection for the lower end of the fuse 4. The semi-elliptical cover 3 includes a semi-elliptical opening 31 that runs from top to bottom, and the lower end of the vertical connecting frame 41 of the fuse 4 is disposed in the semi-elliptical opening 31.

[0032] Specifically, such as Figures 1-4 As shown, where Figure 1 and Figure 4 This is an overall structural diagram of the insulation protection device for fuse 4. Figure 2 and Figure 3 This is a schematic diagram of the insulation protection device used to provide insulation protection for fuse 4.

[0033] The semi-circular opening 11 and the semi-elliptical opening 31 are interconnected with the lower part of the connecting part 2 to form an insulating protective cover 5. The conductive component 43, which is connected to the lower end of the vertical connecting frame 41, is disposed inside the insulating protective cover 5.

[0034] The conductive element 43 is a component of the fuse 4.

[0035] This utility model protects the lower end of the fuse 4 with a semi-circular cover 1 and the lower end of the vertical connecting frame 41 of the fuse 4 with a semi-elliptical cover 3. Since the lower end of the vertical connecting frame 41 is connected to the conductive part 43 of the fuse 4, the semi-elliptical cover 3 can provide insulation protection for the conductive part 43 of the fuse 4, thereby achieving comprehensive and effective insulation protection for the fuse 4.

[0036] Furthermore, the lower end of the fuse 4 is a circular conductive terminal, which is connected to the conductive component 43 and is located inside the insulating protective cover 5.

[0037] Specifically, such as Figure 2 and Figure 3 As shown, the semi-circular cover 1 is mainly used to insulate and protect the circular conductive terminal. Since some animals, such as mice and birds, are likely to appear near the fuse 4, and these animals are conductors, there is a risk of electric shock to the circular conductive terminal. Therefore, the circular conductive terminal is covered by the semi-circular cover 1 to prevent the risk of electric shock.

[0038] Furthermore, the semi-circular cover 1 includes a semi-circular shell 12 and two silicone sheets 13 disposed on the semi-circular shell 12, and the semi-circular shell 12 and the two silicone sheets 13 are both connected to the connecting part 2; the silicone sheets 13 are arc-shaped.

[0039] Specifically, it can be like Figure 1 As shown, the semi-circular cover 1 consists of a semi-circular shell 12 and two silicone sheets 13 disposed on the semi-circular shell 12. The two silicone sheets 13 are used for color differentiation, which can facilitate the staff to mark the number of the fuse 4, thereby improving the maintenance efficiency of the staff.

[0040] Furthermore, the connecting part 2 includes a first protective shell 21 and a second protective shell 22. The first protective shell 21 is connected to the semi-circular shell 12, the silicone sheet 13 and the second protective shell 22; the second protective shell 22 is connected to the semi-elliptical cover 3.

[0041] Specifically, the connecting part 2 is composed of a first protective shell 21 and a second protective shell 22. In this invention, there are two first protective shells 21 and two second protective shells 22. These two first protective shells 21 and two second protective shells 22 form the connecting part below the connecting part 2. The semi-circular opening 11, the semi-elliptical opening 31, and the connecting part below the connecting part 2 together form an insulating protective cover 5 capable of accommodating the circular insulating terminal 42, the conductive component 43, and the lower end of the vertical connecting frame 41. A schematic diagram of the insulating protective cover 5 is shown below. Figure 4 As shown.

[0042] Furthermore, the semi-elliptical cover 3 includes two symmetrical top covers 32 and two symmetrical side panels 33; both the top covers 32 and the side panels 33 are connected to the second protective shell 22.

[0043] Specifically, the semi-elliptical cover 3 is composed of two symmetrical top covers 32 and two symmetrical side guards 33. The semi-elliptical opening 31 formed by the connection of the two top covers 32 allows the vertical connecting frame 41 to pass through. The conductive component 43 connected to the vertical connecting frame 41 can naturally be placed below the connecting part 2, that is, inside the insulating protective cover 5, so as to achieve comprehensive and effective protection for the fuse 4.

[0044] Furthermore, the above figures are merely illustrative of the processes included in the method according to exemplary embodiments of the present invention, and are not intended to be limiting. It is readily understood that the processes shown in the above figures do not indicate or limit the temporal order of these processes. Additionally, it is readily understood that these processes may be executed synchronously or asynchronously, for example, in multiple modules.

[0045] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0047] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
