Problems solved by technology

[0007] However, the conventional shunt resistor module becomes a factor that increases the unit price because injection molding must be added when manufacturing the shunt resistor
Also, if the lead pin 4 is soldered to the PCB in a state where the injection molded structure is not properly joined due to assembly tolerances or incorrect assembly of the shunt resistor and the injection molded product, the lead pin 4 will be damaged even with a slight impact. more likely to break, it may be a quality issue

Abstract

A shunt resistor module may be provided according to the present invention, the shunt resistor module comprising: a resistance part having a predetermined resistance value; plate-shaped terminal parts extending to both sides of the resistance part; shunt resistors which protrude vertically from the terminal parts and have voltage measurement lead pins bent at end portions thereof so as to be parallel to the terminal parts; and a PCB substrate having assembly guide parts formed by cutting the PCT substrate, by a predetermined depth, from the outermost portion to the inside, wherein the voltage measurement lead pins are inserted into the assembly guide parts such that the resistance part and the terminal parts are seated on the front surface of the PCB substrate, and the end portions of the voltage measurement lead pins are caught on the back surface of the PCB substrate.

Description

technical field [0001] The present disclosure relates to a shunt resistor module, and more particularly, to a shunt resistor module including a shunt resistor and a PCB so that the shunt resistor can be mounted without using any structure for supporting the shunt resistor. Insert and secure the shunt resistor directly to the PCB. [0002] This application claims priority from Korean Patent Application No. 10-2019-0098994 filed in Korea on Aug. 13, 2019, the disclosure of which is incorporated herein by reference. Background technique [0003] Currently commercialized secondary batteries include nickel-cadmium batteries, nickel-hydrogen batteries, nickel-zinc batteries, lithium secondary batteries, and the like. Among them, lithium secondary batteries are more prominent due to advantages such as free charge and discharge due to substantially no memory effect, very low self-discharge rate, and high energy density compared to nickel-based secondary batteries. [0004] A power...
