Description

Technical Field

[0001] The utility model relates to a fuse fixing device, comprising a fuse module of the fuse fixing device and an electrical appliance box comprising the fuse module. Background Art

[0002] In the prior art, the fuse in the automobile electrical box is inserted into the housing of the fuse fixing device. The sheet-like insulator of the fuse is inserted into the slot of the housing, and a through hole is formed on the pin of the fuse perpendicular to the sheet-like insulator, and the stud on the housing is inserted into the through hole on the pin to position the pin. In order to prevent the fuse from detaching from the housing, an elastic buckle is usually formed on the housing, and the elastic buckle rests on the top surface of the sheet-like insulator of the fuse. This buckle method can reliably prevent the fuse from detaching from the housing, but there is a problem of excessive interference and difficulty in inserting and removing the fuse. When inserted, the fuse will tilt at a large angle, which will cause the stud on the housing to be misaligned with the through hole on the pin, making it difficult to insert the through hole of the pin. In addition, when pulling out, the elastic buckle needs to be moved to an unlocked position separated from the top surface of the sheet-like insulator. Utility Model Content
