Title:
シャント抵抗式電流検出装置
Document Type and Number:
Japanese Patent JP7116026
Kind Code:
B2
Abstract:
A shunt-resistance type current detector (1) includes a flat-plate shaped shunt resistor (4) joined between a flat-plate shaped first bus bar (2) and a flat-plate shaped second bus bar (3). Each of the bus bars (2, 3) includes respective detection conductors (24, 34) connected to a current detector (6). The shunt resistor (4) and each of the bus bars (2, 3) are joined via weld parts (71, 72). A gap (S1) for mounting the shunt resistor (4) is formed between the first bus bar (2) and the second bus bar (3), and projected parts (23, 33) are formed each being projected toward the gap (S1) from opposing faces (22, 32) opposing to each other in the gap (S1). The shunt resistor (4) comes in contact with each of the projected parts (23, 33) in a top-and-bottom direction.
