본 발명은 휴대단말기용 내장 배터리팩 구조에 관한 것으로, 더욱 상세하게는 상기 축전지의 내부에 보호회로모듈을 설치함으로써, 내장 배터리팩의 안전성을 근본적으로 확보함은 물론, 상기 내장 배터리팩의 생산성을 향상 및 제품의 원가를 절감하여 제품의 가격경쟁력을 상승시키고, 소형단말기 등에 적용이 가능하며, 서로 다른 휴대용 단말기에 동일한 배터리팩을 사용할 수 있어, 서로 다른 배터리팩의 생산에 따른 자원의 낭비를 방지할 수 있는 것이다.The present invention relates to a structure of a built-in battery pack for a mobile terminal, and more particularly, by installing a protection circuit module inside the storage battery, thereby fundamentally securing the safety of the built-in battery pack and improving productivity of the built-in battery pack. It can improve the price competitiveness of the product by improving and reducing the cost of the product, can be applied to small terminals, etc., and the same battery pack can be used for different portable terminals, preventing waste of resources due to the production of different battery packs. You can do it.

일반적으로, 핸드폰, 노트북, 휴대용 개인정보 단말기(PDA : Personal Digital Assistants) 등의 휴대용 단말기는 충방전이 가능한 2차전지인 축전지가 포함된 배터리팩을 단말기 일측면에 탈부착 가능하도록 결합하여 사용하기 때문에, 이동성이 보장되고 휴대가 간편하여 널리 사용되고 있다.In general, portable terminals such as mobile phones, laptops, and personal digital assistants (PDAs) use a battery pack including a storage battery, which is a rechargeable battery that can be charged and discharged, to be detachably attached to one side of the terminal. It is widely used because of its mobility and easy portability.

이러한 휴대용 단말기의 경우, 일정시간동안 사용하게 되면 단말기에 결합된 축전지가 방전되며, 상기 축전지로부터 단말기로 충분한 전원공급이 이루어지지 않게 되어 단말기를 사용하지 못하게 된다.In the case of such a portable terminal, when the battery is used for a predetermined time, the battery coupled to the terminal is discharged, and sufficient power is not supplied from the battery to the terminal, thereby preventing the terminal from being used.

따라서 상기 휴대용 단말기를 재사용하기 위해서는 충전기를 이용하여 상기 방전된 축전지를 충전하여 사용하거나, 여분의 충전된 다른 축전지로 교체한 후 사용하게 된다.Therefore, in order to reuse the portable terminal, the discharged battery is charged by using a charger, or replaced with another charged battery.

상기와 같이 휴대용 단말기에 사용되는 배터리팩은 과전류 또는 과전압이 인 가되면 상기 배터리팩이 소손되는 등의 안전사고가 발생하는 문제점이 있는 바, 대부분의 배터리팩에는 상기와 같은 안전사고를 방지하기 위하여 보호회로(PCM : Protection Circuit Module)가 구성된 기판(PCB : Printed Circuit Board)이 설치되어 있다.As described above, the battery pack used in the portable terminal has a problem that a safety accident occurs such that the battery pack is burned out when an overcurrent or an overvoltage is applied. In order to prevent the safety accident as described above in most battery packs. A printed circuit board (PCB) with a protection circuit module (PCM) is installed.

그리고 상기 기판에 형성된 보호회로가 축전지의 연결단자와 전기적으로 연결되기 위해서는, 납땜용접이나 저항용접 또는 초음파용접 등의 접합방식에 의한 용접공정을 거치게 된다.In addition, in order to electrically connect the protection circuit formed on the substrate to the connection terminal of the battery, a welding process such as soldering, resistance welding, or ultrasonic welding may be performed.

한편, 최근에는 도 4에 나타난 바와 같이, 상기 휴대용 단말기(50)의 일측에 형성된 삽입부(51)로 삽입하여 설치하도록 구성된 내장 배터리팩(이너 팩, Inner Pack)(60)의 사용이 증가되는 추세이며, 상기 내장 배터리팩(60)은 외부충격에 대한 내구성이 높기 때문에 제품의 신뢰성을 향상시킬 수 있는 장점이 있다.On the other hand, as shown in Figure 4, the use of the built-in battery pack (Inner Pack, Inner Pack) 60 configured to insert and install into the insertion unit 51 formed on one side of the portable terminal 50 is increased Since the built-in battery pack 60 has a high durability against external shock, there is an advantage of improving the reliability of the product.

그러나 상기 내장 배터리팩(60) 전체를 인서트 사출하는 방법의 경우, 그 공법상 별도의 전용 사출기가 필요하고, 축전지가 고온 및 고압에 노출됨으로 인해, 상기 축전지의 수명단축 및 폭발의 위험성이 있었다.However, in the case of insert injection molding the entire internal battery pack 60, a separate injection machine is required for the construction method, and the battery is exposed to high temperature and high pressure, thereby reducing the lifespan and explosion of the battery.

또한, 상기 사출시 저온 저압용 수지를 사용하게 때문에, 상기 내장 배터리팩(60)의 강도가 저하되고, 사출품 내부에 비성형 부분이 발생하는 등의 단점이 있었다.In addition, since the low-temperature low-pressure resin is used at the time of injection, the strength of the built-in battery pack 60 is lowered, and there is a disadvantage that an unmolded part is generated inside the injection molded product.

이러한 문제점을 해결하기 위한 것으로, 도 5에 나타난 바와 같이, 보호회로모듈을 별도로 사출 또는 몰딩하여 2차전지인 축전지와 접합하는 방법이 있다.In order to solve this problem, as shown in FIG. 5, there is a method of separately injecting or molding a protective circuit module to bond with a storage battery as a secondary battery.

상기와 같은 방법에 의한 내장 배터리팩(60)은, 축전지(61)의 내부에 정전용 량을 갖는 축전소자가 설치되고, 상기 축전소자의 외측으로 절연지가 감싸도록 설치된 축전지(61)의 일측으로 연결단자(61a)가 설치되어 있다.The built-in battery pack 60 according to the above method is provided with a storage element having a capacitance in the interior of the storage battery 61, and to one side of the storage battery 61 installed so that insulating paper is wrapped outside the storage device. The connecting terminal 61a is provided.

그리고 상기 축전지(61)의 일측으로는, 내부에 보호회로가 설치된 몰딩부재(62)가 설치되며, 상기 축전지(61)의 연결단자(61a)와 보호회로가 전기적으로 연결되도록 구성된다.In addition, a molding member 62 having a protection circuit installed therein is installed at one side of the storage battery 61, and the connection terminal 61a of the storage battery 61 and the protection circuit are electrically connected to each other.

따라서 상기 축전지(61) 및 보호회로모듈이 내설된 별도의 몰딩부재(62)로 구성된 내장 배터리팩(60)을 상기 삽입부(51)에 삽입설치함으로써, 상기 휴대용 단말기(50)에 전원을 공급할 수 있게 되는 것이다.Therefore, by inserting the built-in battery pack 60 consisting of a separate molding member 62 in which the storage battery 61 and the protection circuit module is installed in the inserting portion 51, power can be supplied to the portable terminal 50. It will be possible.

그러나 상기와 같은 일반적인 내장 배터리팩의 경우, 보호회로모듈이 내장된 몰딩부재(62)에 구성된 단자 및 축전지(61)의 연결단자(61a)의 조립강도가 충분히 유지되어야 하나, 외부에서 노출되어 접합되기 때문에 쉽게 떨어지게 되는 문제점이 있었다.However, in the case of the general built-in battery pack as described above, the assembly strength of the terminal and the connection terminal 61a of the storage battery 61, which is formed in the molding member 62 in which the protection circuit module is embedded, should be sufficiently maintained, but exposed from the outside and joined. There was a problem that fall easily.

또한, 상기 보호회로모듈이 내장된 몰딩부재(62)와 상기 축전지(61)가 외부에서 접합되기 때문에 전체적인 내장 배터리팩(60)의 부피가 커지게 되어, 소형 휴대용 단말기에는 적용하기가 어려웠다.In addition, since the molding member 62 in which the protection circuit module is embedded and the storage battery 61 are bonded to the outside, the volume of the entire internal battery pack 60 becomes large, and thus it is difficult to apply to a small portable terminal.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점들을 해결하기 위한 것으로, 상기 축전지의 내부에 보호회로모듈을 설치함으로써, 내장 배터리팩의 안전성을 근본적으로 확보함은 물론, 상기 내장 배터리팩의 생산성을 향상 및 제품의 원가를 절감시킬 수 있는 휴대단말기용 내장 배터리팩 구조를 제공함에 있다.Accordingly, an object of the present invention is to solve the above-mentioned problems, and by installing a protection circuit module inside the storage battery, the safety of the built-in battery pack is fundamentally secured, as well as the productivity of the built-in battery pack. It is to provide a built-in battery pack structure for a mobile terminal that can improve and reduce the cost of the product.

본 발명의 다른 목적은 사용상의 편리성이 개선되어 보다 상품성이 향상되도록 한 휴대단말기용 내장 배터리팩 구조를 제공함에 있다.Another object of the present invention is to provide a built-in battery pack structure for a portable terminal to improve the convenience of use to improve the marketability.

상기 목적을 달성하기 위한 본 발명에 따른 휴대단말기용 내장 배터리팩 구조는, 일측과 다른 일측으로 외부출력단자와 축전지연결단자가 노출된 기판조립체와; 축전지연결단자와 전기적으로 연결되는 보호회로연결단자가 일측에 설치된 축전소자와; 내부에 상기 기판조립체 및 축전소자가 삽입 설치되는 케이스본체와; 케이스본체의 일측을 밀폐하는 커버;를 구비하는 것에 있어서,
배터리팩용 보호회로가 구성된 기판의 일측으로 외부출력단자가 설치되고 다른 일측으로 축전지연결단자가 설치된 보호회로모듈에 몰딩부재를 일체로 몰딩하여 상기 기판조립체를 구성한 것을 특징으로 한다.A built-in battery pack structure for a portable terminal according to the present invention for achieving the above object comprises: a substrate assembly in which an external output terminal and a battery connection terminal are exposed to one side and the other side; A power storage device having a protection circuit connection terminal electrically connected to the battery connection terminal; A case body into which the substrate assembly and the power storage element are inserted; In the case comprising a cover for sealing one side of the case body,
The substrate assembly may be formed by integrally molding a molding member in a protection circuit module in which an external output terminal is installed at one side of a substrate including a battery pack protection circuit and a battery connection terminal is installed at the other side.

따라서 상기 축전지의 내부에 보호회로모듈을 설치하여, 내장 배터리팩의 안전성 확보 및 배터리팩의 생산성을 향상시키고 제품의 원가를 절감할 수 있는 것이다.Therefore, by installing a protection circuit module inside the storage battery, it is possible to secure the safety of the built-in battery pack, improve the productivity of the battery pack and reduce the cost of the product.

또, 사용상의 편리성이 개선되어 보다 상품성이 향상되는 것이다.In addition, the ease of use is improved, and the merchandise is more improved.
