[0027] The following is further described in detail through specific implementation methods:

[0028] 1. Definition

[0029] Fuse: Also known as a current fuse, the IEC127 standard defines it as a fusible link. Its primary function is overload protection. When properly placed in a circuit, the fuse will melt when the current rises abnormally high enough to reach a certain temperature, shutting off the current and ensuring safe circuit operation.

[0030] Fuse box: refers to the box where the fuse is installed.

[0031] 2. The reference numerals in the drawings of the specification include: housing 1, door panel 2, opening 3, fuse box 4, wiring harness 5, connector 6, mounting seat 7, circular limiting portion 8, and connecting portion 9.

[0032] Example 1

[0033] Basically as attached Figure 1 and Figure 3 As shown: A generator includes a housing 1, a fuse box 4 is installed in the housing 1, a fuse is provided in the fuse box 4, the fuse box 4 is connected to the controller through a wiring harness 5, and can also be connected with other electrical components

[0034] An opening 3 is provided on one side of the housing 1. Figure 2As shown, the door panel 2 is provided at the opening 3, and the fuse box 4 is mounted on the side of the housing 1 where the opening 3 is provided. For user convenience, the opening 3 can be provided on a side that is convenient for user operation. To facilitate removal of the door panel 2, the door panel 2 and the opening 3 are detachably connected. In this embodiment, the door panel 2 and the opening 3 are connected by a snap-fit ​​connection.

[0035] The fuse box 4 is mounted on the housing 1 through the mounting seat 7. Specifically, the mounting seat 7 is provided with a slide groove, such as Figure 4 As shown. The fuse box 4 slides into the slide slot and is fixed on the mounting base 7. The fuse box 4 is detachably mounted on the bottom side of the housing 1. The fuse box 4 can be fixed to the housing 1 by bolts, adhesives, or snaps.

[0036] The wiring harness 5 is fixed to the inner wall of the housing 1 through a connector 6. The connector 6 is detachably connected to the inner wall of the housing 1. The connector 6 includes a circular limiting portion 8 in the middle that matches the wiring harness 5 and connecting portions 9 at both ends. Figure 5 As shown, the connecting portion 9 is detachably connected to the inner wall of the housing 1 .

[0037] The specific implementation process is as follows: During use, when the generator is in normal use, the fuse works normally. When the fuse needs to be repaired or the current inside the generator is too high, the fuse is blown and needs to be replaced. After removing the door panel 2 at the opening 3, the fuse box 4 is taken out from the mounting seat 7, and the fuse in the fuse box 4 is repaired or replaced.

[0038] When fixing the wiring harness 5, the positions of other components in the shell 1 can be adjusted. Before installing the wiring harness 5, it is necessary to first pass the wiring harness 5 through the circular limiting portion 8 of the connector 6, and then adjust the position of the wiring harness 5. After the position is adjusted, the connecting portion 9 of the connector 6 is fixed to the inner wall of the shell 1. In this embodiment, the connecting portion 9 of the connector 6 is provided with a threaded hole, and the connector 6 is fixed to the bottom inner part of the shell 1 by bolts.

[0039] Example 2

[0040] The difference from Example 1 is that Figure 6 and Figure 7 In this embodiment, a clamping groove is provided on the mounting seat, and a clamping portion is provided on the side of the clamping groove. After the fuse box is clamped into the clamping groove, the clamping portion can firmly restrict the fuse box on the mounting seat.

[0041] The above is only an embodiment of the present utility model. Common knowledge such as the known specific structures and characteristics in the scheme is not described in detail here. Ordinary technicians in the relevant field are aware of all common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all existing technologies in the field, and have the ability to apply conventional experimental means before that date. Ordinary technicians in the relevant field can improve and implement this scheme in combination with their own abilities under the inspiration given by this application. Some typical known structures or known methods should not become obstacles for ordinary technicians in the relevant field to implement this application. It should be pointed out that for technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the scope of protection of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
