Abstract

A fuse box has a base seat, a plug fuse inserted in the base seat, a breakdown display electric circuit board disposed in the base seat, an upper cover engaging with the base seat, and a connection band connected to the base seat and the upper cover. A light emitting device is disposed on the base seat. The breakdown display electric circuit board has a positive end, a negative end, the plug fuse connected to the breakdown display electric circuit board, a first resistance connected to the plug fuse in parallel, a second resistance connected to the plug fuse in parallel, the second resistance connected to the first resistance in series, the light emitting device connected to the first resistance in parallel and connected to the second resistance in series, a load connected to the plug fuse and the second resistance, and the negative end connected to the load.

Claims

1. A fuse box comprises:

a base seat, a plug fuse inserted in the base seat, a breakdown display electric circuit board disposed in the base seat, an upper cover engaging with the base seat, and a connection band connected to the base seat and the upper cover,

a light emitting device disposed on the base seat,

the breakdown display electric circuit board having a positive end, a negative end, the plug fuse connected to the breakdown display electric circuit board, a first resistance connected to the plug fuse in parallel, a second resistance connected to the plug fuse in parallel, the second resistance connected to the first resistance in series, the light emitting device connected to the first resistance in parallel and connected to the second resistance in series, a load connected to the plug fuse and the second resistance, and the negative end connected to the load,

a first wire connected to the positive end of the breakdown display electric circuit board, and

a second wire connected to the negative end of the breakdown display electric circuit board.

2. The fuse box as claimed in claim 1, wherein the light emitting device is disposed on a bottom of the base seat.
