Description

이동전화 단말기용 밧데리 및 충전기의 체결 구조{JOINT STRUCTURE OF BATTERY AND CHARGER FOR MOBILE PHONE}Joint structure of battery and charger for mobile phone terminal {JOINT STRUCTURE OF BATTERY AND CHARGER FOR MOBILE PHONE}

본 발명은 이동전화 단말기용 밧데리 및 충전기의 체결 구조에 관한 것으로, 더 상세하게는 어떤 형상의 밧데리에 대하여도 충전시 밧데리측 충전단자와 충전기측 충전단자간의 전기적 접촉을 용이하게 확보할 수 있는 구조의 이동전화 단말기용 밧데리 및 충전기의 체결 구조에 관한 것이다.The present invention relates to a fastening structure of a battery for a mobile phone terminal and a charger, and more particularly, a structure that can easily ensure electrical contact between the battery side charging terminal and the charger side charging terminal for charging any shape battery. It relates to a fastening structure of a battery and a charger for a mobile phone terminal.

이동전화 단말기용 밧데리는 셀, 보호 회로 및 외부 단자로 구성되고, 이들중 셀 및 보호 회로는 밧데리의 커버의 내부에 실장되고, 외부단자는 그 일단이 외부에 돌출되고, 그 타단은 보호 회로에 연결된다. 외부 단자 중 밧데리 배면 커버에 돌출된 것이 밧데리측 충전단자이다.A battery for a mobile phone terminal is composed of a cell, a protection circuit and an external terminal, among which a cell and a protection circuit are mounted inside the battery cover, one end of which protrudes to the outside, and the other end of the battery to the protection circuit. Connected. One of the external terminals that protrudes from the battery rear cover is the battery charging terminal.

반면, 충전기의 충전 단자는 충전 회로 기판상의 단자 소켓에 실장되고, 그 콘택(contact)부만 충전기 하우징 외부로 노출 및 고정 설치된다. 또한, 각 충전 단자의 갯수, 접촉 면접 및 노출 위치는 밧데리와 충전기가 체결 수단에 의하여 체결될 때 밧데리측 충전 단자와 일치할 수 있도록 형성된다.On the other hand, the charging terminal of the charger is mounted in the terminal socket on the charging circuit board, and only its contact portion is exposed and fixed to the outside of the charger housing. In addition, the number, contact interview and exposure position of each charging terminal are formed so that they can coincide with the battery side charging terminals when the battery and the charger are fastened by the fastening means.

종래, 이동전화 단말기의 밧데리 형상은 제조 회사나 모델에 따라 다양한 디자인이 개발됨으로 인하여 서로 다르다. 또한, 그 밧데리를 충전하기 위한 충전기의 하우징 상면 형상 또는 하우징의 하부 형상도 밧데리의 배면 또는 하부 형상에 일치되도록 형성하므로, 서로 다르다. 서로 형상이 일치해야 밧데리측 충전단자와 충전기측 충전단자를 용이하게 접촉시킬 수 있기 때문이다. 더구나, 밧데리측 충전단자와 충전기측 충전단자간의 접촉상태를 양호하게 하기 위하여 밧데리와 충전기간의 기구적 체결 수단을 형성하는데, 종래에는 밧데리 커버와 충전기의 하우징에 서로 대응되는 요철부를 형성하여 이들 간에 체결이 이루어지도록 하였다. 그러나, 이러한 체결 수단도 밧데리의 디자인에 따라 그 형성 위치, 형상 및 구조가 달랐다. 이와 같은 밧데리 형상의 다양화와 거기에 따른 밧데리 및 충전기간의 체결 구조의 차이는 다른 제조사의 밧데리 및 충전기간에 호환성이 없는 문제를 야기할 뿐만아니라, 동일한 제조사간의 밧데리 및 충전기간에도 호환성이 없는 문제를 야기하여 왔다.Conventionally, the battery shape of a mobile phone terminal is different because various designs are developed according to a manufacturer or a model. In addition, since the upper shape of the housing of the charger or the lower shape of the housing for charging the battery is formed so as to match the rear or lower shape of the battery, they are different from each other. This is because the battery-side charging terminal and the charger-side charging terminal can be easily contacted with each other when the shapes coincide with each other. Furthermore, in order to improve contact between the battery side charging terminal and the charger side charging terminal, a mechanical fastening means is formed between the battery and the charger. Conventionally, uneven parts corresponding to each other are formed on the battery cover and the housing of the charger to be fastened therebetween. This was done. However, these fastening means also differed in their position, shape and structure depending on the design of the battery. Such diversification of battery shape and the difference in fastening structure between batteries and chargers not only cause incompatible problems between batteries and chargers of different manufacturers, but also incompatible problems between batteries and chargers between the same manufacturers. It has caused.

종래, 핸즈프리와 핸드폰을 체결하는 수단으로 자석이 사용되어 왔다. 그러나 핸즈프리와 핸드폰을 체결하는 자석은 핸즈프리 또는 핸드폰의 어느 하나에 1극의 자석을 부착하고, 다른 하나에는 철판등 자성체를 부착하여, 이들이 접근하면 서로 다른 극간에 서로 인력이 작용하도록 하는 구조를 가졌다. 그러나 이러한 구조에 의하여서는, 핸즈프리의 상면상의 1지점과 접촉되는 밧데리의 배면 상의 접촉 지점이 항상 일정하지는 않아 핸즈프리와 핸드폰등에 형성된 단자간을 자동으로 접촉시키는 수단으로 사용하기에는 불가능 하였다. 그러나, 자력을 이용하되, 두 면을 항상 일정한 지점에서 접촉하게 할 수 있는 구조의 자석 배치를 할 수 있다면, 자력을 단순한 부착이 아닌, 단자간의 자동 접촉 수단으로도 사용할 수 있는 것이다.Conventionally, magnets have been used as a means for engaging hands-free and mobile phones. However, the magnet that connects the hands-free and the mobile phone has a structure in which one pole magnet is attached to either the hands-free or the mobile phone, and a magnetic material such as an iron plate is attached to the other, so that when they approach each other, the attraction force is applied to each other. . However, with this structure, the contact point on the back of the battery which is in contact with one point on the top of the hands free is not always constant, so it is impossible to use it as a means of automatically contacting the terminals formed on the hands free and the mobile phone. However, if the magnetic force can be used, but the magnet arrangement of the structure that the two surfaces can always be contacted at a certain point can be used, the magnetic force can be used as an automatic contact means between the terminals, not just attachment.

출원인은 서로 다른 표면 자극을 갖는 2개의 자석을 이용하여, 도 1의 M1 또는 M2와 같이 동일한 평면상에 그 표면이 위치하도록 한 자석쌍을 만들고, 이들 자석쌍 2개를 도 1a에 도시된 바와 같이 접극 시키면, 도 1b에 도시된 바와 같이 각 자석쌍의 반대 자극끼리 자력이 작용하여 2개 자석쌍의 표면이 평면적으로 완전히 일치되는 접촉 및 체결이 이루어질 뿐만 아니라, 2개의 자석쌍간에 접촉 지점도 매번 동일한 지점끼리 다시 접촉함을 확인하였다. 상기 자석쌍은 표면 자극이 반대인 영구자석편 2개를 절연하여 접합하는 방법으로 만들거나, 1개의 자성체편을 반대되는 자극을 절반씩 갖도록 자화시킴으로써 만들어질 수 있다. 자석을 전자석으로 할 경우 2개의 절연된 자성체에 코일을 감아 반대 방향의 전류를 흘려 줌으로서도 상기 자석쌍을 만들 수 있다.Applicants use two magnets with different surface magnetic poles to create a pair of magnets whose surfaces are located on the same plane, such as M1 or M2 in FIG. 1, and the two pairs of magnets as shown in FIG. 1A. When contacted together, as shown in FIG. 1B, magnetic forces act on opposite magnetic poles of each pair of magnets to make contact and fastening of the surfaces of the two pairs of magnets perfectly matched in a planar manner, as well as contact points between the two pairs of magnets. It was confirmed that the same points were contacted again each time. The magnet pair may be made by insulating and joining two permanent magnet pieces having opposite surface magnetic poles, or by magnetizing one magnetic piece to have opposite magnetic poles. In the case of using a magnet as an electromagnet, the magnet pair can be formed by winding a coil around two insulated magnetic bodies and flowing a current in opposite directions.

상술한 종래 기술의 문제점을 해결하고자 안출된 본 발명은 밧데리의 형상에 상관없이 충전단자 갯수 및 충전단자간의 간격만 일치한다면, 용이하게 밧데리측 충전단자와 충전기측 충전단자를 접촉시킬 수 있는 이동전화 단말기용 밧데리 및 충전기의 체결 구조를 제공하는데 그 목적이 있다.The present invention devised to solve the problems of the prior art described above is a mobile phone which can easily contact the battery side charging terminal and the charger side charging terminal, provided that the number of charging terminals and the distance between the charging terminals match, regardless of the shape of the battery. It is an object of the present invention to provide a fastening structure of a battery for a terminal and a charger.

상기 2개의 자석쌍의 접촉면의 면적은 서로 동일하게 한다.The areas of the contact surfaces of the two magnet pairs are equal to each other.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도면에 도시된 실시예는 자석으로 영구자석편을 사용하는 경우를 예시한 것이나, 자석으로 전자석을 이용하는 실시예 대하여도 당업자라면 용이하게 구현할 수 있는 것이다.The embodiment illustrated in the drawings illustrates a case of using a permanent magnet piece as a magnet, but an embodiment using an electromagnet as a magnet can be easily implemented by those skilled in the art.

도 1은 본 발명에 따른 이동전화 단말기용 밧데리 및 충전기의 체결 구조에 체결 수단으로 사용되는 자석쌍 2개를 도시한 사시도를, 도 2는 도 1에 도시된 2개의 자석쌍을 밧데리의 배면과 충전기의 상면에 각1개씩 서로 반대 극성이 마주 보도록 부착한 상태를 도시한 사시도를, 도 3은 도 2에서 밧데리와 충전기가 체결된 상태의 측단면도를 각각 나타낸다.1 is a perspective view showing two magnet pairs used as a fastening means in a fastening structure of a battery for a mobile phone terminal and a charger according to the present invention, and FIG. 2 shows the two magnet pairs shown in FIG. 1 is a perspective view illustrating a state in which the opposite polarities face each other on the upper surface of the charger, and FIG. 3 is a side cross-sectional view of the battery and the charger in FIG. 2, respectively.

도 1을 참조하면, 본 발명은 서로 다른 표면자극을 갖는 2개의 자석을 동일한 평면에 배치시켜 자석쌍(M1 또는 M2)을 만들고, 이들 자석쌍 2개(M1 및 M2)를 서로 접근시킬 경우 항상 평면적으로 일정하게 부착되는 성질, 즉 자석쌍 1의 접촉면의 각 지점이 항상 자석쌍 2의 접촉면의 일정한 지점과 부착되는 성질을 이용한 것이다. 이때, 자석쌍 M1과 자석쌍 M2의 접촉 면적이 동일한 것이 가장 바람직하다.Referring to FIG. 1, the present invention always arranges two magnets having different surface magnetic poles on the same plane to form a pair of magnets M1 or M2, and the two pairs of magnets M1 and M2 always approach each other. The property of attaching uniformly in the plane, that is, each point of the contact surface of the magnet pair 1 always attaches to a certain point of the contact surface of the magnet pair 2 is used. At this time, it is most preferable that the contact area of the magnet pair M1 and the magnet pair M2 is the same.

도 2에 도시된 바와 같이 밧데리측 충전단자(12a~12d) 및 충전기측 충전단자(32a~32d)와 상기 2개의 자석쌍(M1,M2)의 상대 위치를 충전단자간에 접촉이 일어날 수 있게 배치하면, 밧데리를 충전기 근처에 접근시킬 때마다 밧데리측 충전단자(12a~12d)가 충전기측 충전단자(32a~32d)에 자동으로 접촉되게 된다.As shown in FIG. 2, the relative positions of the battery side charging terminals 12a to 12d and the charger side charging terminals 32a to 32d and the two magnet pairs M1 and M2 are arranged to allow contact between the charging terminals. In this case, whenever the battery is approached near the charger, the battery side charging terminals 12a to 12d automatically come into contact with the charger side charging terminals 32a to 32d.

이때, 상기 충전기 하우징의 상면(31)을 평면 또는 평면 형상에 가깝게 형성할 경우, 밧데리의 배면 형상에 상관없이 어떤 형상의 밧데리의 충전단자도 충전기측 충전단자에 용이하게 접촉할 수 있는 것이다.In this case, when the upper surface 31 of the charger housing is formed to be flat or close to the flat shape, the charging terminal of the battery of any shape can easily contact the charger side charging terminal irrespective of the rear shape of the battery.

도 3을 참조하면, 자석쌍 1(M1) 및 자석쌍 2(M2)가 접촉면에서 항상 일정한 지점끼리 체결될 경우, 자석쌍 1(M1)의 표면상의 각 지점에 대하여 일정한 위치를 점하고 있는 밧데리측 단자(12b)는 자석쌍 2(M2)의 표면상의 각 지점에 대하여 일정한 위치를 점하고 있는 충전기측 단자(32b)에 정확히 접촉하게 되는 것이다.Referring to FIG. 3, when the magnet pair 1 (M1) and the magnet pair 2 (M2) are always fastened at a predetermined point on the contact surface, the battery occupies a fixed position with respect to each point on the surface of the magnet pair 1 (M1). The side terminal 12b is in exact contact with the charger side terminal 32b which has a fixed position with respect to each point on the surface of the magnet pair 2 M2.

이렇게 함으로써, 충전단자의 갯수 및 충전단자간 거리만 일치하는 경우라면 1개의 충전기에 의하여 밧데리의 형상에 상관없이 어떤 형상의 밧데리라도 충전이 가능하게 된다.By doing so, if only the number of charging terminals and the distance between the charging terminals are matched, one battery can be charged with any shape regardless of the shape of the battery.

이상, 첨부한 도면을 참조하여 본원 발명의 일 실시예를 설명하였으나, 본원 발명의 기술적 사상 및 그 보호 범위능 여기에 한정되는 것은 아니며, 청구범위에 기재된 사항과 실질적으로 동일한 모든 실시예에 미친다 할 것이다.As mentioned above, although one Example of this invention was described with reference to an accompanying drawing, The technical idea of this invention and its protection scope are not limited to this, and it extends to all the Example which is substantially the same as the matter of a claim. will be.

본 발명에 의하면, 밧데리의 형상에 상관없이 충전단자 갯수 및 충전단자간의 간격만 일치한다면, 용이하게 밧데리측 충전단자와 충전기측 충전단자를 접촉시킬 수 있을 뿐만 아니라, 특히 충전단자 갯수 및 충전단자간의 간격을 모두 통일시킨다면, 제조사나 모델에 상관없이 모든 형상의 밧데리에 대하여 동일한 충전기를 사용할 수 있는 효과가 있다.According to the present invention, irrespective of the shape of the battery, if only the number of charging terminals and the distance between the charging terminals match, not only the battery side charging terminal and the charger side charging terminal can be easily contacted, but also the number of charging terminals and the charging terminal If the spacing is unified, the same charger can be used for all shapes of batteries, regardless of make or model.
