Abstract

The fuse assembly contains a first casing member with a first chamber, and a second casing member with a second chamber. An enclosed space is thereby formed by joining the first and second casing members together. A disconnection member is sandwiched between the first and second casing members. The disconnection member contains two electrodes and a fuse element between the two electrodes. Each electrode contains a first lateral section, a vertical section, and a second lateral section, jointly and integrally forming a C-like shape. The electrodes are positioned at two opposing ends of the second casing member and the fuse element is housed in the enclosed space. The enclosed space allows the fuse element to break off completely, thereby avoiding electrical arc and achieving enhanced usage safety.

Claims (7)

1. A fuse assembly, comprising:

a first casing member having a bottom-open first chamber;

a second casing member having a top-open second chamber; and

a disconnection member having two electrodes and a fuse element whose two ends are connected to said electrodes, respectively;

wherein said electrodes are positioned at two opposing ends of said second casing member, respectively; said first casing member is stacked on said second casing member, thereby forming an enclosed space; said disconnection member is sandwiched between said first and second casing members; and said fuse element is housed in said enclosed space; each electrode contains a first lateral section, a vertical section, and a second lateral section, sequentially connected in this sequence; said fuse element is connected to said first lateral sections; at the junction between each end of said fuse element and said first lateral section of an electrode, two opposing slits are provided, thereby forming a neck section between said fuse element and said first lateral section; inside said first chamber, there are two parallel, opposing, and downward extending pressing pieces; inside said second chamber, there are two parallel, opposing, and upward extending receiving pieces, each having a gap along a top edge; said disconnection member is joined to said second casing member with said neck section at each end of said fuse element received by said gap of a receiving piece; and said pressing pieces fill said gaps and tightly press said neck sections of said fuse element, respectively.

2. The fuse assembly according to claim 1 , wherein a notch is provided along a right-angled junction between said first lateral section and said vertical section.

3. The fuse assembly according to claim 1 , wherein, on a bottom side of said second casing member, there are two indentations along two opposing shorter edges of said bottom side, respectively; and said second lateral sections are received by said indentation, respectively.
