이와 같이 상기 스프링블럭(60)의 압지부(70)와 전극핀(30) 사이에 전극 편(90)이 압지하는 과정에서 상기 압지부(70)는 몸체(61)의 안착홈(64)을 따라 지지판(71)이 후진됨과 동시에 상기 지지판(71)의 돌출편(72)이 상기 몸체(61)의 끼움공을 따라 후진되면서 상기 판스프링(74)에 의해 소정의 탄성력으로 지지판(71)을 밀착시킴에 따라 상기 압지부(70)가 전극편(90)을 압지하는 것이다.As described above, in the process of pressing the electrode piece 90 between the holding part 70 and the electrode pin 30 of the spring block 60, the holding part 70 opens the seating groove 64 of the body 61. Accordingly, the support plate 71 is reversed and at the same time the protruding piece 72 of the support plate 71 is retracted along the fitting hole of the body 61, thereby supporting the support plate 71 with a predetermined elastic force by the leaf spring 74. In close contact, the pressure-sensitive portion 70 presses the electrode pieces 90.

이와 동시에, 상기 압지부(70)가 밀착됨에 따라 이 압지부(70)에 의해 탄성지지되는 상기 몸체(61)가 후진되는데, 상기 몸체(61)는 고정수단(80)과 부시(65)를 축으로 하여 후진되면서 상기 스프링의 탄성력에 의해 지지되는 것이다.At the same time, the body 61, which is elastically supported by the pressure-sensitive portion 70, is reversed as the pressure-sensitive portion 70 is in close contact with the body 61, which fixes the fixing means 80 and the bush 65. It is supported by the elastic force of the spring while being retracted to the axis.

이와 같이, 상기 스프링블럭(60)은 전극편(90)을 압지함에 있어, 상기 압지부(70)의 판스프링(74)과 몸체(61)의 스프링에 의해 한층 더 안정적으로 전극편(90)을 압지할 수 있는 것이다.As described above, the spring block 60 holds the electrode piece 90 more stably by the spring of the leaf spring 74 and the body 61 of the holding part 70. It can be pressed.

한편, 상기 전극핀(30)의 압지돌기(31)가 길이방향으로 형성되어 상기 전극편(90)의 접촉저항을 줄여 접지력을 배가시킬 수 있는 것이다.On the other hand, the pressing protrusion 31 of the electrode pin 30 is formed in the longitudinal direction to reduce the contact resistance of the electrode piece 90 can double the grounding force.

이상과 같이 본 발명의 실시예에 대하여 상세히 설명하였으나, 본 발명의 권리범위는 이에 한정되지 않으며, 본 발명의 실시예와 실질적으로 균등의 범위에 있는 것까지 본 발명의 권리범위가 미친다.As described above, embodiments of the present invention have been described in detail, but the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to the embodiments of the present invention.

따라서, 본 발명은 전지의 전극편을 스프링블럭과 전극핀에 의해 한층 더 견고하게 압지하여 접촉시 발생되는 접촉저항을 줄이고 보다 적극적으로 접촉되도록 하여, 전지의 충방전시 전류 흐름을 안정적으로 유도하는 효과가 있다.Accordingly, the present invention further firmly presses the electrode piece of the battery by the spring block and the electrode pin to reduce the contact resistance generated during contact and to make the contact more actively, thereby stably inducing the current flow during charging and discharging of the battery. It works.
