Abstract

The present invention provides a current sensing resistor and a fabrication method thereof. The current sensing resistor includes a conductive body comprising a resistor portion and a pair of electrode portions connecting to two ends of the resistor portion, a receiving blind hole disposed on a top surface of each of the pair of electrode portions, and a detection terminal disposed on the receiving blind hole. The detection terminal includes a base fixed in the receiving blind hole and a terminal pin protruding from the top surface.

Description

technical field [0001] The present invention relates to a resistive device, and more particularly, to a current sensing resistor having improved mechanical strength and better electrical performance. Background technique [0002] Current sense resistors, such as shunt resistors, are known in the art. When a current sense resistor is connected in series to a load and a current is applied to it, a voltage drop is created which can be measured and referenced to estimate the magnitude of the current. [0003] Current sense resistors are commonly used in a variety of electrical equipment. Generally, a current sensing resistor includes a metal plate resistor having a resistor body made of a metal material having a small temperature coefficient of resistance, and a pair of electrodes made of a metal material having high conductivity connected to both ends of the resistor body. [0004] Typically, the fabrication of current sense resistors utilizes a surface soldering process. H...
