Melt structure

A melt structure is characterized in that a plurality of narrow diameters are arranged on a conductive body and can reduce the conductive sectional area of the melt, the distance between the narrow diameters in the middle of the melt is larger than that between the narrow diameters on the two sides of the melt, the middle of the melt is further provided with at least one U-shaped bending part, and the two sides of the melt are coated with arc extinguishing glue respectively. According to the utility model, the performance of the fuse can be improved, and the product performance is ensured to meet various high-voltage grades in the modern society. 一种熔体结构，熔体包括在一导电本体上设有多条可使熔体导电截面积减小的窄径，熔体中部处的窄径间的间距大于熔体两侧处的窄径间的间距，熔体中部还设有至少一U形的弯折部，熔体的两侧处分别涂覆有灭弧胶。本实用新型可提高熔断器的性能，保证产品性能以满足现代社会各种高电压等级。
