Description

접촉단자 교체가 가능한 2차 전지 충반전장치의 커넥터{Replaceable Probe-pin of secondary battery polarity charge and discharge Connector}Replaceable probe-pin of secondary battery polarity charge and discharge connector

본 발명은 다품종 대응형 2차전지 극성변환 충방전장치에 관한 것으로, 더욱 상세하게는 접촉단자를 교체할 수 있도록 구성한 2차 전지 충반전장치의 커넥터에 관한 것이다.The present invention relates to a multi-type secondary battery polarity conversion charging and discharging device, and more particularly, to a connector of a secondary battery charging and discharging device configured to replace a contact terminal.

일반적으로 2차전지는 1차전지와는 달리 사용 후 전원을 연결하여 충전하면 가역반응을 거쳐 재사용할 수 있는 충전 가능한 배터리로 스마트 폰과 넷북, 노트북 등의 휴대형 기기와 전기자동차 및 에너지 저장장치 등에 사용된다.In general, the secondary battery is a rechargeable battery that can be reused through reversible reaction when the power is connected and charged after use, unlike the primary battery. It is used in portable devices such as smart phones, netbooks, laptops, electric vehicles, and energy storage devices. do.

또한, 스마트 휴대형 기기의 발달로 인한 2차전지의 수요는 점차 확대되고 있으며, 다양한 디자인의 기기들이 출시되면서 전지의 형태 및 크기 종류도 다양하게 출시되고 있다.In addition, the demand for secondary batteries is gradually increasing due to the development of smart portable devices, and various types and sizes of batteries are being released as devices of various designs are released.

이러한 2차전지는 충방전 공정을 거쳐 제품으로 출시되는데 충방전 공정은 2차전지에 일정한 전력을 공급하여 충전하고 방전시키는 작업을 반복하며 2차전지의 충전용량 및 제품특성을 확인하는 공정이다.The secondary battery is released as a product through a charging / discharging process. The charging / discharging process is a process of checking charging capacity and product characteristics of a secondary battery by repeating the operation of charging and discharging by supplying constant power to the secondary battery.

이때, 2차전지의 충방전 공정에서 정해진 전류치를 얼마나 정밀하게 지속적으로 충전하고 방전해 줄 수 있는지가 가장 중요하다.At this time, it is most important to accurately and continuously charge and discharge the current value determined in the charging and discharging process of the secondary battery.

그러나 종래의 2차 전지 충방전장치는 다량의 2차전지를 충방전 시키기 위해서 트레이에 다량의 2차 전지를 삽입한 상태로 다량의 2차전지가 제공된다.However, the conventional secondary battery charging and discharging device is provided with a large amount of secondary batteries with a large amount of secondary batteries inserted in a tray to charge and discharge a large amount of secondary batteries.

이때, 트레이 안에 개재된 2차 전지는 고정되지 않아 유격이 발생한다.At this time, the secondary battery interposed in the tray is not fixed and a play occurs.

이와 같은 상태로 제공되는 트레이를 2차 전지 충방전장치에 세팅하고 충방전하게 되면 미세한 바람과 기계의 무브먼트에 의해 진동이 발생하게 되는데, 종래의 커넥터의 구조로는 2차 전지의 탭을 충분히 가압하지 못해 탭과 커넥터의 접촉단자가 서로 접촉된 상태에서 진동에 의해 비벼지거나 미끄러지는 현상이 발생된다.When the tray provided in such a state is set in the secondary battery charging and discharging device and charged and discharged, vibration is generated by fine wind and movement of the machine. In the conventional connector structure, the tab of the secondary battery is sufficiently pressed. When the contact terminal of the tab and the connector are not in contact with each other, the phenomenon of rubbing or sliding due to vibration occurs.

이러한 현상은 2차 전지의 탭과 커넥터의 접촉단자 사이에 접촉 저항을 변화시키는 요소로 작용되어 결과적으로 충방전 시 안정성이 감소하게 되는 원인이 된다.This phenomenon acts as an element that changes the contact resistance between the tab of the secondary battery and the contact terminal of the connector, resulting in a decrease in stability during charging and discharging.

또한, 기존의 배터리 측정용 클립 타입 2차 전지 충방전장치의 커넥터는 일체형으로 커넥터 접촉단자의 마모 시 전체를 교체하여야 했으며, 이로 인해 가격 상승 및 환경오염을 발생 시켰다.In addition, the connector of the existing battery type clip-type secondary battery charging and discharging device was integral, and the entire connector contact terminal had to be replaced when it was worn, resulting in an increase in price and environmental pollution.

따라서, 접촉단자만을 교체함으로써 재사용을 통한 원가 절감 및 환경오염을 방지할 수 있는 커넥터의 개발이 요구된다.Therefore, it is required to develop a connector capable of preventing cost reduction and environmental pollution through reuse by replacing only the contact terminal.
