Description

차량용 배터리 터미널 조립체Vehicle Battery Terminal Assembly
본 발명은 차량용 배터리 터미널 조립체에 관한 것으로, 더욱 상세하게는 차량용 배터리의 폴 단자에 배터리 터미널을 조립 시 배터리 터미널의 회전을 방지하고 자동차 충돌사고시 배터리 터미널이 배터리 폴 단자에서 이탈되지 않도록 구성된 차량용 배터리 터미널 조립체에 관한 것이다.The present invention relates to a vehicle battery terminal assembly, and more particularly, a vehicle battery terminal configured to prevent rotation of the battery terminal when assembling the battery terminal to the pole terminal of the vehicle battery and prevent the battery terminal from being separated from the battery pole terminal in a car crash accident It is about assembly.
일반적으로 차량 등에 적용되는 배터리는 축전 및 방전을 위한 플러스(+) 및 마이너스(-) 단자가 돌출 형성되는데, 이것을 폴(pole) 단자(또는 포스트 단자)라고 한다. 이러한 폴 단자에는 축전 및 방전을 위한 접속 단자인 배터리 터미널이 결합된다.In general, batteries applied to vehicles, etc. have positive (+) and negative (-) terminals protruding for power storage and discharge, which are called pole terminals (or post terminals). A battery terminal, which is a connection terminal for power storage and discharge, is coupled to these pole terminals.
즉, 배터리 터미널은 배터리의 폴 단자에 체결되고 전선과 연결되어 정션박스 및 각종 전장품에 전류를 공급하는 역할을 한다. 이러한 배터리 터미널은 차량 전원 공급의 출발점이기 때문에 그 접촉이 좋지 못하면 시동조차 잘 걸리지 않을 수도 있다.That is, the battery terminal is fastened to the pole terminal of the battery and connected to the electric wire to supply current to the junction box and various electronic devices. Since these battery terminals are the starting point of the vehicle's power supply, if the contact is not good, the engine may not even start well.
현재 배터리의 폴 단자와 배터리 터미널을 연결할 때, 폴 단자를 배터리 터미널로 감싼 상태에서 체결 볼트와 너트를 조여 체결한다. When connecting the current battery pole terminal to the battery terminal, tighten the fastening bolt and nut while the pole terminal is wrapped with the battery terminal.
이때, 배터리 터미널의 체결 볼트와 너트를 일정 수준의 토크로 조임으로써 폴 단자에 강하게 체결할 수 있으나, 차량의 진동이나 충격에 의해 체결 볼트와 너트의 풀림 및 헐거움이 발생하면 폴 단자와 배터리 터미널의 체결력이 감소하게 된다.At this time, by tightening the fastening bolts and nuts of the battery terminal to a certain level of torque, it can be strongly fastened to the pole terminal. The clamping force is reduced.
이에 따라, 폴 단자와 배터리 터미널 사이의 접촉저항이 증가하는 문제가 발생되며, 이와 같은 형상이 더 진행되면 최종적으로 배터리 터미널이 폴 단자에 이탈하는 심각한 현상이 발생할 수 있다.Accordingly, there is a problem in that the contact resistance between the pole terminal and the battery terminal increases, and if such a shape further progresses, a serious phenomenon in which the battery terminal finally departs from the pole terminal may occur.
또한, 적정 조임 토크를 상회하는 힘으로 체결 볼트와 너트를 조일 경우, 배터리 터미널이 변형되거나 끊어질 수 있으며 반대로 체결 볼트와 너트를 적정 조임 토크 이하의 힘으로 조일 경우, 배터리 터미널과 폴 단자 간 접촉저항 증가 및 단자 이탈 등의 문제가 발생할 수 있었다.In addition, if the tightening bolt and nut are tightened with a force exceeding the appropriate tightening torque, the battery terminal may be deformed or broken. Problems such as resistance increase and terminal detachment may occur.
더욱이, 배터리 터미널은 회전을 방지하는 별도의 수단이 구비된 바 없으므로 차량의 진동으로 배터리 터미널이 미세 회전하며 원뿔대 형태인 폴 단자를 타고 오르며 최종적으로 이탈하게 된다. 또한, 자동차 충돌사고시 충격에 의한 이탈 또한 발생하게 된다.Moreover, since the battery terminal is not provided with a separate means for preventing rotation, the battery terminal rotates finely due to vibration of the vehicle, climbs on the truncated cone-shaped pole terminal, and finally departs. In addition, in the case of a car crash accident, the departure due to the impact also occurs.
따라서, 배터리의 폴 단자에서 배터리 터미널의 이탈과 회전을 억제하도록 개선된 형태의 차량용 배터리 터미널 조립체의 개발이 요구되고 있는 실정이다.Accordingly, there is a demand for the development of an improved type of vehicle battery terminal assembly to suppress the separation and rotation of the battery terminal from the pole terminal of the battery.
