New Description: [New Technology Field] The present invention relates to a battery module for a hand-held electronic device, and more particularly to a hand-held type between a battery protection circuit board and a battery core with a terminal set for guiding A battery module of an electronic device and a battery protection circuit board thereof. [Prior Art] As the demand for power storage of handheld electronic devices increases and environmental awareness rises, most of the batteries required for power supply for handheld electronic devices today use reusable secondary batteries, such as lithium secondary batteries and nickel. Hydrogen batteries and so on. As shown in FIG. 1 , a battery module of a current handheld electronic device has a battery core 11 and a battery protection circuit board for controlling battery charging and discharging (

In the past, the battery protection circuit board 12 was used to conduct the positive electrode (1) and the negative electrode 112 of the electromagnetic core u to the battery protection material 12 by means of two metal foils (e.g., (4)) or wires. As the volume of the hand-held electronic device develops toward a short, light and thin size, the size of the battery module 1 is also becoming smaller and smaller. The above welding method needs to be carried out at a high temperature to cause the battery core U and the battery board 12 to be destroyed. The field is welded very small on the electromagnetic core u and the battery (4) on the circuit board 12'. Not only is the construction complicated and the conduction is poor. Since the welding wire 14 and the battery protection electrode 2 are welded, the battery module 1 is difficult to repair. Therefore, at present, when the battery core 115 Ge 5 M304777 electric path is broken, most of the battery protection circuit board 12 is faulty or the lead between the two is discarded. The entire battery module 1 is wasteful. [New content] Connect the battery core and the battery protection point' to achieve the assembly capacity.
