The utility model relates to a structure capable of pre-fixing NTC (Negative Temperature Coefficient) and saving PCB (Printed Circuit Board) space in a battery pack, which is characterized by comprising an outer shell, a module support arranged in the outer shell and provided with a battery cell, and a PCB arranged on the module support, a pre-embedded pipe is arranged between a first side surface of the PCB and the battery cell, an NTC temperature sensor with a head exposed outside is arranged in the pre-embedded pipe in a penetrating manner, and the NTC temperature sensor is connected with the battery cell. A pin of the NTC temperature sensor is wound from the side edge of the PCB to the second side face of the PCB to be welded so as to be electrically connected with the PCB. According to the utility model, the installation of the NTC temperature sensor on the PCB is realized, a through groove does not need to be formed in the PCB, and the enough layout area of the PCB is ensured. 本实用新型涉及一种电池包中可预固定NTC及节省PCB
