The present invention relates to a battery pack for a non-welding assembly type mobile phone terminal, which prevents and uses a built-in PCM in a pair of elastically coupled moldings to be electrically connected to a battery cell.

더욱 상세하게는, 배터리 셀에 도통가능하게 접속되는 양극/음극단자가 인서 트몰딩성형된 몰딩물을 본딩에 의해 배터리 셀에 고정하고, 몰딩성형된 PCM이 내장된 몰딩물을 인서트몰딩물에 탄성결합시킴에 따라, 양극/음극단자 및 PCM의 스폿용접공정 및 용접 불량유무를 확인하는 검사공정이 생략되고, PCM을 일반 PC재를 이용하여 고온,고압에서 사출성형하여 내부 회로의 전기적 특성 저하되는 것을 방지할수 있도록 한 무용접 조립식 휴대폰 단말기용 배터리 팩에 관한 것이다.More specifically, the anode / cathode terminal, which is electrically connected to the battery cell, fixes the molded molding insert to the battery cell by bonding, and the molding containing the molded PCM is elastic to the insert molding. By combining, the spot welding process of the anode / cathode terminal and PCM and the inspection process to check for welding defects are omitted, and the PCM is injection molded at high temperature and high pressure using general PC materials, thereby deteriorating the electrical characteristics of the internal circuit. The present invention relates to a battery pack for a non-welded cell phone terminal which can be prevented.

일반적으로, 휴대폰 배터리 팩은 배터리 셀(cell)과, 과충전/과전류 방지 회로부와, 가요성 인쇄회로기판(flexible printed circuit board)과, 외부 단자와 연결을 위한 터미널 단자 등이 패키지형태로 몰딩성형되어 있다.In general, a mobile phone battery pack is molded into a battery cell, an overcharge / overcurrent protection circuit portion, a flexible printed circuit board, and a terminal terminal for connecting to an external terminal. have.

전술한 과충전/과전류 방지 회로는 인쇄회로기판상에 부착되는 회로를 보호하기 위해 몰드 패키지화 되어 있는 COB(chip on board)타입과, 몰드 패키지화되어 있지않은 PCM타입으로 분류된다.The above-mentioned overcharge / overcurrent protection circuits are classified into a chip on board (COB) type which is packaged in a mold and a PCM type which is not packaged in a mold to protect a circuit attached to a printed circuit board.

도 1에 도시된 바와 같이, 종래 기술에 의한 휴대폰 단말기용 배터리 팩은, 음극탭(1)이 상면에 형성되는 배터리 셀(2)과, 배터리 셀(2) 상면에 도통가능하게 스폿용접 고정되는 양극단자(3)(Ni plate)와, 음극탭(1)에 스폿용접 고정되는 음극단자(4)와, 배터리 셀(2)에 스폿용접 고정되는 양극단자(3)와 음극단자(4)에 스폿용접 고정되며 배터리 셀(2)에 과전류, 과충전되는 것을 방지하는 패턴화된 PCM(5)과, PCM(5)과 음극단자(4)의 상호 접촉으로 인해 쇼트되는 것을 방지하는 절연지(6)(insulation plate)를 구비한다.As shown in FIG. 1, the battery pack for a mobile phone terminal according to the related art is a battery cell 2 having a negative electrode tab 1 formed on an upper surface thereof, and a spot weld fixed to the upper surface of the battery cell 2. On the positive electrode terminal 3 (Ni plate), the negative electrode terminal 4 fixed to the spot welding to the negative electrode tab 1, the positive electrode terminal 3 and the negative electrode terminal 4 fixed to the spot welding to the battery cell (2) Patterned PCM 5 for spot welding and preventing overcurrent and overcharging in the battery cell 2, and insulating paper 6 for preventing shorting due to mutual contact between the PCM 5 and the negative electrode terminal 4 (insulation plate).

이때, 전술한 PCM(5)을 외부로 부터 보호하기 위하여 PCM(5)을 저온저압 작업조건에서 몰딩성형하는 전용 사출기의 금형에 소정온도와 압력을 유지하여 공급되는 핫멜트(hot melt)에 의해 몰딩성형하게 된다. 즉 PCM(5)을 저온 작업조건(80∼100℃)에서 핫멜트 공급에 의해 사출성형하는 경우, 소정온도와 압력을 유지하여 핫멜트를 일정량으로 공급하는 핫멜트 공급부와, 핫멜트에 의해 PCM(5)을 몰딩성형하는 금형부와, 핫멜트 공급부와 금형부 등의 구동부를 제어하는 제어부 등의 부대설비가 필요하여 사출기 가격이 고가이고, 핫멜트 원료를 수입하게되어 원가비용이 상승되는 문제점을 갖는다.At this time, in order to protect the above-mentioned PCM (5) from the outside molding by hot melt supplied to maintain the predetermined temperature and pressure to the mold of the injection molding machine for molding the PCM (5) in the low-temperature low-pressure working conditions Molding.

또한, 배터리 셀(2)에 스폿용접되는 양극/음극단자(3,4)에 패턴화된 PCM(5)을 스폿용접한 후, 전용 사출기에 의해 PCM(5)을 몰딩성형하는 작업공수 증가로 인해 작업능률 및 생산성이 떨어져 동업종 분야에서 경쟁력이 떨어지고, 양극/음극단자(3,4), PCM(5)의 스폿용접 및 몰딩성형시 발생되는 인체에 유해한 냄새로 인해 작업자 건강을 해치는 문제점을 갖는다.Further, after spot welding the PCM 5 patterned on the anode / cathode terminals 3 and 4, which are spot welded to the battery cell 2, the number of working hours for molding the PCM 5 by a dedicated injection molding machine is increased. Due to its low work efficiency and productivity, it is not competitive in the industry, and it is harmful to human health due to harmful odors generated during spot welding and molding of anode / cathode terminals (3,4) and PCM (5).
