Abstract

The invention discloses a fuse, which comprises an insulating shell and a fuse main body, wherein a plurality of separated containing cavities are arranged in the insulating shell, the fuse main body comprises a fusing part and conductive electrodes located at the two ends of the fusing part, the fusing part comprises a plurality of fuse bodies connected end to end, each fuse body is correspondingly arranged in the corresponding containing cavity, and the conductive electrode extends out of the insulating shell. The safety performance of the fuse provided by the invention is higher.

Description

technical field [0001] The invention relates to the field of electrical protection components, in particular to a fuse. Background technique [0002] Fuses are usually used as circuit protection devices and are electrically connected to the components to be protected in the circuit. A commonly used fuse includes an insulating case and a melt disposed in the cavity of the insulating case. When an overcurrent occurs, the melt melts and cuts off the circuit, so as to avoid damage to the components or circuits to be protected. The melt may form an arc during melting. If the arc is not extinguished, the arc may further damage the circuit to be protected by allowing unwanted current to flow to the circuit components, so it is desirable to extinguish the arc as soon as possible. However, the cavities of the above-mentioned insulating shells are single-connected, and the arcs generated when the melt melts are easy to fuse with each other, thereby causing greater combustion and rele...
