Patent ID: 8531264

Claim:
A current sensing resistor made by a highly electrically conductive metal plate, the metal plate comprising: a middle portion; a first portion, located at one side of the middle portion and having a first slot; and a second portion, located at the other side of the middle portion opposite to the first portion and having a second slot, wherein each of the first portion and the second portion is divided into a current terminal and a sensing terminal by the first slot and the second slot respectively, and the current terminals of the first portion and the second portion have a length that is respectively greater than that of the sensing terminals of the first portion and the second portion, characterized in that the middle portion has a middle slot, and the length of the middle slot is used for controlling the stability of resistance for the current sensing resistor, and in that the length of the middle slot is greater than or equal to the length of the first or second slot plus the length of the sensing terminal of the first or second portion.
