Abstract
The present invention relates to a current sensing device comprising: a bus bar including a plurality of low-resistance metal portions separated from each other with a resistance portion therebetween; a printed circuit board arranged below the bus bar; a plurality of fixing pins which are joined to the metal portions of the bus bar to fix the bus bar on the printed circuit board and provide a current path between the metal portions and the printed circuit board; and at least one Hall sensor module. At least a portion of the Hall sensor module is inserted into a sensor hole formed in at least one of the low-resistance metal portions of the bus bar.

A current sensing device comprising:
- a bus bar including two low-resistance metal portions separated from each other with a resistance portion therebetween;
- a printed circuit board arranged below the bus bar;
- a plurality of fixing pins which are joined to the metal portions of the bus bar to fix the bus bar on the printed circuit board and provide a current path between the metal portions and the printed circuit board;
- and
- two Hall sensor modules, wherein each of the two low-resistance metal portions comprises a sensor hole, wherein each of the two Hall sensor modules is at least partially inserted into the corresponding sensor hole, and wherein the two sensor holes are disposed symmetrically with respect to the resistance portion interposed therebetween.
