[0002] The car fuse box is used to protect the various electrical circuits of the car. It can effectively limit the rated current carried by each electrical circuit of the car to a safe range, ensuring that the various circuits on the car will not cause damage to electrical components or fire due to heavy loads.

[0003] Existing fuse boxes generally include a box body, and a fuse, a conductive plate, and a terminal block that are sequentially connected inside the box body. The box body is formed with openings corresponding to the terminal blocks. During assembly, the positive electrode of the vehicle battery passes through the opening and is fixedly connected to the terminal block. Since the fuse, conductive plate, and terminal block are all installed in the same cavity of the box body, the opening of the box body results in poor sealing. The fuse is easily affected by moisture or corrosion, which can cause a short circuit and affect the normal operation of the vehicle circuit. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that fuses are easily affected by moisture and affect the normal operation of automobile circuits, thereby providing an automobile fuse box with good sealing and high reliability.
