fuse

Abstract

The invention relates to a fuse, which is provided with a first casing and a second casing, wherein the first casing and the second casing are mutually combined, an accommodating chamber is formed between the first casing and the second casing, a disconnecting device is arranged between the first casing and the second casing and is provided with two electrodes and a fusing part, each electrode is provided with a first sheet body, a side sheet body and a second sheet body which are mutually connected so that the occurrence of fracture or poor contact condition of the electrodes in the use process is avoided, the fusing part is positioned in the accommodating chamber and can be completely disconnected through the accommodating chamber, the occurrence of the electric arc phenomenon is avoided, and the use safety is ensured.

Description

technical field

[0001] The invention relates to a fuse, especially a structure which can avoid arc phenomenon and whose electrodes can conduct electricity reliably. Background technique

[0002] The existing fuse has an upper layer, two electrodes, a fuse, and a lower layer, and each electrode has a top sheet body, a side sheet body and a bottom sheet body connected by electric welding. The upper layer and the lower layer are superimposed on each other, two electrodes are respectively arranged at opposite ends of the lower layer, and the fuse is electrically connected to the two electrodes, and the fuse is interposed between the upper layer and the lower layer.

[0003] As mentioned above, the existing fuse structure has the following disadvantages:

[0004] 1. Since the upper layer and the lower layer are solid bodies, the fuse cannot be completely disconnected when it is blown, and an arc phenomenon will occur, causing danger in use.

[0005] Two, the top sheet body, the...
