본발명은 리튬폴리머전지 및 캐패시터용 충,방전기에 관한 것으로 특히, 극편의 표면을 찍으면서 접촉되도록 전극편에 다수개의 톱니형접촉부를 형성함으로서리튬폴리머전지 및 캐패시터에 연결된 극편의 표면으로 이물질이나 산화피막이 형성된 상태에서도 접촉저항을 최소화하여 충,방전이 가능토록 된 리튬폴리머전지 및 캐패시터용 충,방전기의 전극편 구조에 관한 것이다.The present invention relates to a charge and discharge device for lithium polymer batteries and capacitors. In particular, by forming a plurality of serrated contact portions on the electrode pieces so as to contact while taking the surface of the pole pieces, foreign matter or oxidation to the surface of the pole pieces connected to the lithium polymer battery and capacitor. The present invention relates to a structure of an electrode piece of a lithium polymer battery and a capacitor for charging and discharging, which can be charged and discharged by minimizing contact resistance even when a film is formed.

종래 리튬폴리머전지 및 캐패시터에 충,방전을 하는 충,방전 장치의 전극편은 도1및 도2에 나타내었다.1 and 2 show electrode pieces of a charging and discharging device for charging and discharging a lithium polymer battery and a capacitor.

상기의 전극편(2)은 2개가 한쌍으로 지지체(1)에 결합되어 있는바, 한개의 전극편(2)은 전압 측정을 위해 결합되고 나머지 한개의 전극편(2)은 전류를 통전시키기 위해 결합된다.The two electrode pieces 2 are coupled to the support 1 in a pair, and one electrode piece 2 is coupled for voltage measurement and the other electrode piece 2 is used to conduct current. Combined.

그리고, 상기 한쌍의 전극편(2) 상단부에는, 리튬폴리머전지 및 캐패시터 (21)의 극편(22)표면과 접촉하기 위한 반원형접촉부(3)가 각각 형성되어 있다.At the upper ends of the pair of electrode pieces 2, semicircular contact portions 3 for contacting the surface of the pole piece 22 of the lithium polymer battery and the capacitor 21 are formed, respectively.

즉, 상기 리튬폴리머전지 및 캐패시터(21)가 충,방전을 하기 위해 전극편(2)의 반원형접촉부(3)와 절연체(11)사이로 하강하여 위치되면 상기 절연체(11)와 지 지체(1)가 리튬폴리머전지 및 캐패시터(21)에 연결된 극편(22)을 사이에 두고 서로 오무려지면서 도2에 나타낸 바와같이 극편(22)을 압지하는 상태가 된다.That is, when the lithium polymer battery and the capacitor 21 are positioned lowered between the semicircular contact portion 3 and the insulator 11 of the electrode piece 2 to charge and discharge the insulator 11 and the support member 1. 2 is pressed against each other with the pole pieces 22 connected to the lithium polymer battery and the capacitor 21 interposed therebetween, thereby pressing the pole pieces 22 as shown in FIG.

따라서, 상기 극편(22)을 압지하고 있는 전극편(2)들에 의해 리튬폴리머전지 및 캐패시터(21)에 충,방전을 시킬 수 있게 된다.Therefore, the lithium polymer battery and the capacitor 21 can be charged and discharged by the electrode pieces 2 holding the pole pieces 22.

그러나, 상기와 같은 종래의 기술은, 전극편(2)에 형성된 반원형접촉부(3)가 반원형상으로 형성되어 있기 때문에 극편(22)의 표면과 선접촉을 하는 상태가 된다.However, in the conventional technique as described above, since the semicircular contact portion 3 formed on the electrode piece 2 is formed in a semicircular shape, it is in a state of making linear contact with the surface of the pole piece 22.

즉, 도3에 나타낸 바와같이 리튬폴리머전지 및 캐패시터(21)의 극편(22)표면으로 이물질이나 산화피막이 형성된 상태에서는 전극편(2)의 반원형접촉부(3)가 극편(22)과 직접 선접촉을 하지 못하고 이물질이나 산화피막을 사이에 둔 상태로 위치하게 된다.That is, as shown in FIG. 3, the semicircular contact portion 3 of the electrode piece 2 is in direct line contact with the pole piece 22 in a state where foreign matter or an oxide film is formed on the surface of the pole piece 22 of the lithium polymer battery and the capacitor 21. It can not be located with the foreign matter or oxide film sandwiched between them.

따라서, 상기 중간부에 위치되는 극편(22)의 이물질이나 산화피막에 의해 전류의 흐름이 차단되면서 접촉저항이 발생하게 되므로 리튬폴리머전지 및 캐패시터 (21)에 정상적인 충,방전을 하지 못하게 되는 문제점을 가지고 있었다.Therefore, since the flow of current is blocked by foreign matter or oxide film of the pole piece 22 located in the middle portion, the contact resistance is generated, thereby preventing normal charging and discharging of the lithium polymer battery and the capacitor 21. I had.

상기와 같이 리튬폴리머전지 및 캐패시터(21)에 충,방전이 되지 않을 경우에는 작업자가 해당 리튬폴리머전지 및 캐패시터(21)를 기체로 부터 분리하여 극편 (22)에 적층되어 있는 이물질이나 산화피막등을 제거하는 작업을 별도로 행해야 했기 때문에 매우 번거롭고 불편한 문제점과 한번에 마무리될 작업을 2-3회에 걸쳐 반복적으로 수행해야 했기 때문에 작업능률도 저하되는 문제점을 가지고 있었다.When charging and discharging are not performed on the lithium polymer battery and the capacitor 21 as described above, a worker separates the lithium polymer battery and the capacitor 21 from the gas and deposits a foreign material or an oxide film stacked on the pole piece 22. Because it was necessary to perform a separate operation to remove a very cumbersome and inconvenient problem and had to perform the work to be completed at the same time 2-3 times repeatedly had a problem that the work efficiency is also reduced.

이러한 종래의 문제점등을 햐결 보완하기 위한 본발명의 목적은, The purpose of the present invention to solve these conventional problems, etc.,

리튬폴리머전지 및 캐패시터에 연결된 극편의 표면으로 이물질이나 산화피막이 형성된 상태에서도 충,방전이 가능토록 하는 목적을 제공한다.It provides the purpose of charging and discharging even in the state where foreign matter or oxide film is formed on the surface of the pole piece connected to the lithium polymer battery and the capacitor.

상기의 목적을 달성하기 위하여 본발명은,In order to achieve the above object, the present invention,

극편의 표면을 찍으면서 접촉되도록 전극편에 다수개의 톱니형접촉부를 형성시키면 본발명의 목적을 달성할 수 있게 된다.By forming a plurality of serrated contact portions on the electrode pieces so as to contact while photographing the surface of the pole piece, the object of the present invention can be achieved.

본발명의 구성을 첨부된 도면에 의해 상세히 설명하기로 한다.The configuration of the present invention will be described in detail with reference to the accompanying drawings.

리튬폴리머전지 및 캐패시터(121)에 연결된 극편(122)의 표면으로 이물질이나 산화피막이 형성된 상태에서도 충,방전이 가능토록 하기 위해 극편(122)의 표면을 찍으면서 접촉되도록 전극편(102)에 형성되는 다수개의 톱니형접촉부(103)를 구비한 구성이다.Formed on the electrode piece 102 so as to contact while taking the surface of the pole piece 122 in order to enable charging and discharging even in the state of foreign matter or oxide film formed on the surface of the pole piece 122 connected to the lithium polymer battery and the capacitor 121. It is a structure provided with the several toothed contact part 103 which becomes.

그리고, 상기 톱니형접촉부(103)가 리튬폴리머전지 및 캐패시터(121)에 연결된 극편(122)의 표면에 직각으로 찍히면서 접촉되도록 전극편(102)에 형성되는 절곡부(104)를 더 구비하였다.Further, the toothed contact portion 103 was further provided with a bent portion 104 formed on the electrode piece 102 such that the tooth contact portion 103 was in contact with the surface of the pole piece 122 connected to the lithium polymer battery and the capacitor 121 at right angles. .

이와같이된 본발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention as described above is as follows.

먼저, 리튬폴리머전지 및 캐패시터(121)가 충,방전을 하기 위해 전극편(102)의 톱니형접촉부(103)와 절연체(111)사이로 하강하여 위치되면 상기 절연체(11)와 지지체(101)가 리튬폴리머전지 및 캐패시터(121)에 연결된 극편(122)을 사이에 두고 서로 오무려지면서 도5에 나타낸 바와같이 극편(122)을 압지하는 상태가 된다.First, when the lithium polymer battery and the capacitor 121 are lowered and positioned between the toothed contact portion 103 and the insulator 111 of the electrode piece 102 to charge and discharge the insulator 11 and the support 101. The pole pieces 122 are connected to each other with the pole pieces 122 connected to the lithium polymer battery and the capacitor 121 interposed therebetween, and the pole pieces 122 are pressed as shown in FIG. 5.

이때, 상기 전극편(102)에 형성된 다수개의 톱니형접촉부(103)는 리튬폴리머전지 및 캐패시터(121)의 극편(122)표면을 찍으면서 도6에 나타낸 바와같이 접촉을 하게 된다.At this time, the plurality of toothed contact portions 103 formed on the electrode pieces 102 are in contact with each other as shown in FIG. 6 while photographing the surface of the pole piece 122 of the lithium polymer battery and the capacitor 121.

즉, 상기 다수개의 톱니형접촉부(103)의 뾰족한 선단부들이 극편(122)의 내부로 파고든 상태로 극편(112)과 접촉을 하게 되므로 극편(112)의 표면에 이물질이나 산화피막이 형성된 상태라도 이에 아랑곳하지 않고 확실한 접촉이 가능해진다.That is, since the pointed tip portions of the plurality of toothed contact portions 103 are in contact with the pole piece 112 in a state of digging into the inside of the pole piece 122, even if a foreign material or an oxide film is formed on the surface of the pole piece 112 It is possible to make sure contact without.

따라서, 상기 톱니형접촉부(103)와 극편(122)사이에 접촉저항이 발생하지 않게 되고 아울러 전류의 흐름이 막히는 일이 없게 되므로 표면에 이물질이나 산화피막이 형성된 상태의 리튬폴리머전지 및 캐패시터(121)에도 용이하게 충,방전을 시킬 수 있게 된다.Therefore, the contact resistance between the toothed contact portion 103 and the pole piece 122 is not generated and the current flow is not blocked, so the lithium polymer battery and the capacitor 121 having the foreign matter or the oxide film formed on the surface thereof. It is also possible to easily charge and discharge.

특히, 종래와 같이 극편(122)에 적층되는 이물질이나 산화피막등을 제거하는 별도의 작업이 없이도 접촉저항을 최소화하여 충,방전이 가능하게 되어 충,방전효율을 향상시킬 수 있고 작업능률도 향상시킬 수 있게 된다. In particular, charging and discharging is possible by minimizing contact resistance without separate work of removing foreign matter or oxide film laminated on the pole piece 122 as in the related art, thereby improving charging and discharging efficiency and improving work efficiency. You can do it.

그리고, 본발명에서는 도8에 나타낸 바와같이 전극편(102)에 절곡부(104)를 형성시킴으로서 상기의 톱니형접촉부(103)가 리튬폴리머전지 및 캐패시터(121)에 연결된 극편(122)의 표면에 직각으로 찍히면서 안정된 접촉을 하도록 배려하였다.In the present invention, as shown in FIG. 8, the bent portion 104 is formed on the electrode piece 102 so that the tooth contact portion 103 is connected to the lithium polymer battery and the capacitor 121. It was taken to make stable contact while being stamped at right angles.

이와같이된 본발명은 리튬폴리머전지 및 캐패시터에 연결된 극편의 표면으로 이물질이나 산화피막이 형성된 상태에서도 접촉저항을 최소화하여 충,방전이 가능토록 함으로서 극편에 적층되는 이물질이나 산화피막등을 제거하는 별도의 작업이 없이도 충,방전이 가능하게 되어 충,방전효율을 향상시킬 수 있고 작업능률도 향상시킬 수 있는 유용한 효과를 가진다.Thus, the present invention minimizes contact resistance even when foreign matter or oxide film is formed on the surface of the pole piece connected to the lithium polymer battery and the capacitor so that charging and discharging is possible, thereby eliminating the foreign matter or oxide film deposited on the pole piece. Without this, charging and discharging are possible, thereby improving charging and discharging efficiency and having a useful effect of improving work efficiency.
