전해액 누출방지구조를 구성한 자동차용 배터리 단자 제조 방법 및 이에 의해 제조된 배터리 단자{Manufacturing method of automotive battery terminal with electrolyte leakage prevention structure}Manufacturing method of automotive battery terminal with electrolyte leakage prevention structure

본 발명은 전해액 누출방지구조를 구성한 자동차용 배터리 단자 제조 방법 및 이에 의해 제조된 배터리 단자에 관한 것으로서, 더욱 상세하게는 주조 공정을 이용하여 배터리 단자의 외형을 완성하는 배터리단자외형완성단계(S100)와 전해액 누액방지구조를 배터리단자의 하부링형상부에 형성하기 위하여 전조가공돌기부(110)를 일정 간격 다수 측면에 구성하고 있는 전조가공장치(100)를 이용하여 상기 배터리단자외형완성단계에서 완성된 배터리 단자의 하부링형상부(210)를 가공하는 전해액누출방지구조형성단계(S200)를 거치게 되면 완성된 배터리 단자의 하부링형상부에 형성된 전해액 누액방지구조에 의한 누액 이동 경로는 배터리단자외형완성단계(S100)에서 완성된 배터리 단자의 하부링형상부(210)에 의한 누액 이동 경로보다 길게 되며, 이동 방향을 다수 바꾸게 됨으로써, 누액을 방지할 수 있는 효과를 제공할 수 있는 전해액 누출방지구조를 구성한 자동차용 배터리 단자 제조 방법 및 이에 의해 제조된 배터리 단자에 관한 것이다.The present invention relates to a method of manufacturing a battery terminal for a vehicle having an electrolyte leakage prevention structure and a battery terminal manufactured thereby, and more particularly, a battery terminal appearance completion step of completing the appearance of the battery terminal using a casting process (S100) The battery completed in the battery terminal appearance completion step by using the rolling processing device 100 comprising a rolling processing protrusion 110 on a plurality of sides at a predetermined interval in order to form an electrolyte leakage prevention structure on the lower ring shape of the battery terminal. When the electrolyte leakage prevention structure forming step (S200) of processing the lower ring-shaped part 210 of the terminal is passed, the leakage movement path by the electrolyte leakage prevention structure formed on the lower ring-shaped part of the completed battery terminal is the battery terminal appearance completion step (S100). ) Is longer than the flow path of leakage by the lower ring-shaped part 210 of the battery terminal completed in ), and by changing a number of movement directions, a battery for automobiles with an electrolyte leakage prevention structure that can provide an effect to prevent leakage It relates to a terminal manufacturing method and a battery terminal manufactured thereby.

일반적으로 자동차용 배터리 단자를 보호하는 커버는 배터리의 단자에 연결되는 케이블에 구비되는 외부 단자와 배터리 단자를 보호하도록 덮는 역할을 한다.In general, a cover for protecting a battery terminal for a vehicle serves to cover an external terminal and a battery terminal provided in a cable connected to the terminal of the battery.

이는 배터리 단자와 이에 결합되는 외부 단자가 외부의 요인으로 인하여 오염되는 것을 방지함과 동시에, 신체에 접촉하게 되어 감전이 될 가능성을 차단하기 위함이다. This is to prevent contamination of the battery terminal and the external terminal coupled thereto due to external factors, and to block the possibility of electric shock due to contact with the body.

또한, 자동차용 배터리 단자의 커버는 배터리의 플러스 단자와 마이너스 단자를 각각 덮어 상호 쇼트되는 것도 방지한다.In addition, the cover of the battery terminal for a vehicle covers the positive terminal and the negative terminal of the battery, respectively, to prevent a mutual short circuit.

그러나, 배터리 단자에 외부 단자가 연결되고 고정너트로 고정하여 기계적 결합되는 과정 중에 고정너트가 누락되거나 불완전하게 체결되는 경우에 배터리 단자커버로 배터리 단자를 차폐하면 외부에서는 이를 확인할 수 없는 문제점이 있었다.However, when the external terminal is connected to the battery terminal and the fixing nut is missing or incompletely fastened in the process of being mechanically coupled by being connected to the battery terminal, there is a problem that it cannot be confirmed from the outside when the battery terminal is shielded with a battery terminal cover.

한편, 상기와 같이 배터리 단자를 포함하고 있는 납축전지는 일반적으로 자동차 시동용으로 사용하고 있었다.Meanwhile, as described above, a lead acid battery including a battery terminal has been generally used for starting a vehicle.

일반적으로 자동차용 배터리(납축전지) 단자의 재질은 납으로 구성되고 단자 하부의 외부는 플라스틱 수지로 덥히고 하부의 내부는 공기와 전해액에 접촉된다.In general, the material of the terminal of a battery for a vehicle (lead storage battery) is made of lead, the outer part of the lower part of the terminal is warmed with plastic resin, and the inner part of the lower part is in contact with air and electrolyte.

배터리 충전 중 가스가 발생되며 가스 및 전해액은 단자와 플라스틱 수지사이의 계면으로 누출될 수 있기 때문에 배터리 제조회사에서는 누출을 방지할 수 있게 단자하부의 구조를 복잡하게 하고 단자하부에 특수 코팅액을 도포하여 계면으로 누액 차단을 하고 있으나, 이를 위하여 별도의 누액 방지구조를 제공하기 위한 공정이 추가적으로 소요되기 때문에 이에 따른 제조 원가 및 제조 시간이 상승하는 문제점이 발생하게 되었다.Gas is generated during battery charging, and gas and electrolyte may leak through the interface between the terminal and the plastic resin, so battery manufacturers complicate the structure of the lower part of the terminal to prevent leakage and apply a special coating solution to the lower part of the terminal. Although the leakage is blocked at the interface, since a process for providing a separate leakage prevention structure is additionally required for this purpose, there is a problem in that the manufacturing cost and manufacturing time are increased accordingly.

따라서, 본 발명에서는 배터리 단자에 전해액 누출방지 구조가 채택된 새로운 기술이 채택된 자동차용 배터리 단자의 개발을 제안하게 된 것이다. Accordingly, in the present invention, it is proposed to develop a battery terminal for a vehicle employing a new technology in which an electrolyte leakage prevention structure is adopted in the battery terminal.
