DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a cable detachable transparent protective cover, comprising a first transparent connector 1 and a second transparent connector 6 in a cylindrical shape, the first transparent connector 1 and the second transparent connector 6 are made of transparent plastic, a cylindrical cavity 4 is provided in the first transparent connector 1 and the second transparent connector 6, one end of the first transparent connector 1 and the second transparent connector 6 are connected by plugging and unplugging, Figure 2 The specific structure of the plug-in connection is that an annular groove 11 is provided on the surface of one end of the first transparent connector 1 close to the second transparent connector 6, and an annular inner cavity 10 is provided on the inner surface of the opening of the second transparent connector 6. The annular groove 11 is inserted into the annular inner cavity 10 and the inner surfaces of the two are flush; Figure 2 As shown, an annular limiting seat 9 is provided on the side of the annular groove 11 away from the annular inner cavity 10, and a connecting sleeve 3 is sleeved on the annular limiting seat 9. An annular limiting flange 8 in contact with the annular limiting seat 9 is provided in one end of the connecting sleeve 3 away from the second transparent connecting body 6, so that the annular limiting flange 8 and the annular limiting seat 9 form a limiting structure, so that the connecting sleeve 3 can only rotate;

[0023] An internal thread is provided in the connecting sleeve 3, and an external thread 5 matching the internal thread is provided on the end surface of the second transparent connecting body 6. The connecting sleeve 3 can be threadedly connected to the end of the second transparent connecting body 6 by rotating. At this time, the annular groove 11 is inserted into the annular inner cavity 10, which can achieve a better sealing effect and also increase the strength between the two transparent connecting bodies.

[0024] like Figure 1 and Figure 3 As shown, the two cylindrical cavities 4 are used to place glass tube fuses 7, and the size of the glass tube fuses 7 matches the size of the cylindrical cavities 4, so that the glass tube fuses will not shake in the cylindrical cavities 4;

[0025] like Figure 1As shown, a connecting wire 2 is provided in the ends of the first transparent connector 1 and the second transparent connector 6 away from each other, and an elastic electrode sheet 12 is connected to the end of the connecting wire 2 close to the cylindrical cavity 4. The elastic electrode sheet 12 is preferably a copper alloy sheet. Connecting parts 16 are provided on both sides of the end of the elastic electrode sheet 12 away from the cylindrical cavity 4. The core of the connecting wire 2 is wrapped and fixed by the two connecting parts 16. It can also be said that the core of the connecting wire is clamped and fixed by the two connecting parts, and then the connecting wire, the connecting part 16 and the elastic electrode sheet 12 are buried together in the ends of the first transparent connector 1 and the second transparent connector 6 to form an integrated structure.

[0026] like Figure 3 and Figure 4 As shown, the end of the elastic electrode sheet 12 away from the connecting wire extends into the cylindrical cavity 4, and the elastic electrode sheet 12 is in elastic contact with the end of the glass tube fuse 7. In order to make the elastic electrode sheet 12 better contact with the end of the glass tube fuse 7, as shown in FIG. Figure 3 As shown, the elastic electrode sheet 12 located in the cylindrical cavity 4 is provided with a first arc-shaped curved portion 13 and a second arc-shaped curved portion 14, the first arc-shaped curved portion 13 and the second arc-shaped curved portion 14 are arranged opposite to each other, and the first arc-shaped curved portion 13 and the second arc-shaped curved portion 14 are two identical U-shaped curved structures;

[0027] A contact surface 15 is formed between the first arc-shaped curved portion 13 and the second arc-shaped curved portion 14, and the contact surface 15 is parallel to the end of the glass tube fuse 7. At the end support portion 17 of the second arc-shaped curved portion 14, the support portion 17 is parallel to the contact surface 15. The first arc-shaped curved portion 13 and the second arc-shaped curved portion 14 make the elastic electrode sheet 12 more elastic. When the end of the glass tube fuse 7 contacts the contact surface 15, the two first arc-shaped curved portions 13 and the second arc-shaped curved portions 14 simultaneously generate a reaction force, making the contact between the contact surface and the end of the glass tube fuse more stable.

[0028] Further, such as Figure 1 and Figure 3 As shown, the length of the first transparent connector 1 is greater than that of the second transparent connector 6, so that the length of the glass tube fuse 7 located in the first transparent connector 1 is greater than the length of the tube fuse 7 located in the second transparent connector 6. It should be noted that when the fuse in the glass tube fuse 7 is burned out, it can be directly observed through the transparent connector. However, in order to more conveniently observe the condition of the fuse, the length of the first transparent connector 1 is designed to be longer, so that the condition of the fuse can be directly observed from the first transparent connector 1. If the fuse is burned out, the two transparent connectors can be opened and replaced with a new glass tube fuse.
