Abstract

Disclosed is a fusible link unit which is capable of being directly connected to a battery, and which includes: a band plate portion integrally formed in a bus bar; two fuse circuit-forming members contiguously formed respectively to two sides of the band plate portion; and bodies each including an electrically insulating housing formed onto a corresponding one of the fuse circuit-forming members by insert molding. Flanges as long as the entire width of the band plate portion are formed respectively in No end edges of the band plate portion by bending the flanges from the two end edges in the plate thickness direction. The bodies are arranged side-by-side with a clearance equal to the width of the band plate portion by bending the bodies along the two side edges of the band plate portion in the same direction.

Claims

1. A fusible link unit capable of being directly connected to a battery;

comprising;

a bus bar including;

a band plate portion provided in a central portion of the bus bar;

flanges provided respectively to two end edges of the band plate portion, the flanges being as long as an entire width of the band plate portion, and the flanges being provided virtually perpendicularly to the band plate portion; and

two fuse circuit-forming members consecutively installed respectively to two side edges of the band plate portion, and

two bodies including electrically insulating housings which are formed by insert molding onto the fuse circuit-forming members, respectively,

wherein the band plate portion, the flanges and the two fuse circuit-forming members are integrally formed,

the two fuse circuit-forming members and the two bodies are bent along the two side edges of the band plate portion in the same direction so that a plan vision of the two fuse circuit-forming members and the two bodies with the band plate portion forms a right square bracket, and

the fuse circuit-forming members are accordingly arranged side-by-side with a clearance equal to the width of the band plate portion.

2. The fusible link unit according to claim 1, wherein

each of the two fuse circuit-forming members includes:

a interconnecting plate portion;

first fuse elements connected to the connecting plate; and

load connecting terminal portions connected to the interconnecting plate portion via the respective first fuse elements, and

one of the two fuse circuit-forming members further includes;

a second fuse element; and

a battery terminal connecting portion which is connected to the interconnecting plate portion via the second fuse element, which is directly connected to a battery.

3. The fusible link unit according to claim 1, further comprising covers with which exposed portions of the bus bar are covered.

4. The fusible link unit according to claim 1, wherein

free ends respectively of the two bodies are provided with first and second engagement portions which engage with each other, and

when the two bodies are bent, the free ends respectively of the two bodies are fixed to each other by the engagement of the first and second engagement portions with each other.
