Description

Technical Field

[0001] The utility model relates to the technical field of fuses, in particular to a fuse box. Background Art

[0002] A fuse box is a box used to install and store fuses for the electrical systems of cars, motorcycles, other motor vehicles or equipment. The fuse box is usually located in the engine compartment or cab of the vehicle. Its function is to protect the vehicle's electrical system from damage caused by circuit problems such as overload or short circuit. When an abnormal current appears in the circuit, the fuse will melt and cut off the current, thereby protecting the electrical equipment. If the fuse is correctly placed in the circuit, then when the current abnormally rises to a certain height and temperature, the fuse will melt and cut off the current, thereby protecting the safe operation of the circuit. At present, most fuse boxes are sealed shell structures. When the fuse is operating normally, it will also generate high heat. In order to ensure the waterproofness of the fuse, the shell is generally designed to be a sealed cover. However, due to the poor internal thermal conductivity and heat dissipation, the stable use of the fuse will be affected to a certain extent; the top of the fuse box is mostly sealed with a transparent material, which has poor strength, waterproofness and protection, and is easily affected by external factors; the fuse can only be pulled out and observed by the naked eye to see whether it is blown. The electrical system of multiple fuses is cumbersome and inconvenient to detect, and it is urgently needed to be improved. Therefore, we propose a fuse box. Utility Model Content
